[Technical Field]

[0001] The present invention relates to a user equipment and a method.

[Background Art]

[0002] In the 3rd Generation Partnership Project (3GPP), a radio access method and a radio network for cellular mobile communications (hereinafter, referred to as Long Term Evolution, or Evolved Universal Terrestrial Radio Access) have been studied. In LTE (Long Term Evolution), a base station device is also referred to as an evolved NodeB (eNodeB), and a terminal device is also referred to as a User Equipment (UE). LTE is a cellular communication system in which multiple areas are deployed in a cellular structure, with each of the multiple areas being covered by a base station device. A single base station device may manage multiple cells. Evolved Universal Terrestrial Radio Access is also referred as E-UTRA.

[0003] In the 3GPP, the next generation standard (New Radio: NR) has been studied in order to make a proposal to the Intemational-Mobile-Telecommunication-2020 (IMT- 2020) which is a standard for the next generation mobile communication system defined by the International Telecommunications Union (ITU). NR has been expected to satisfy a requirement considering three scenarios of enhanced Mobile BroadBand (eMBB), massive Machine Type Communication (mMTC), and Ultra Reliable and Low Latency Communication (URLLC), in a single technology framework.

[0004] For example, wireless communication devices may communicate with one or more devices using a communication structure. However, the communication structure used may only offer limited flexibility and/or efficiency. As illustrated by this discussion, systems and methods that improve communication flexibility and/or efficiency may be beneficial.

[Description of Embodiments]

[0025] A user equipment (UE) is described. The UE may comprise high-layer processing circuitry configured to acquire a first RRC parameter, a second RRC parameter, a third RRC parameter, and a fourth RRC parameter, and transmission circuitry configured to transmit a PUSCH in multiple slots. If the first RRC parameter is set to pusch-RepTypeB, the transmission circuitry is configured to perform frequency hopping for the PUSCH transmission based on the second RRC parameter set to interRepetition or interSlot. If the first RRC parameter is set to pusch-RepTypeA, the transmission circuitry is configured to perform frequency hopping for the PUSCH transmission based on the third RRC parameter set to interRepetition, interSlot, or intraSlot. If the first RRC parameter is set to pusch-RepTypeB and the second RRC parameter is not configured, the transmission circuitry is configured not to perform frequency hopping for the PUSCH transmission. If the first RRC parameter is set to pusch-RepTypeA and the third RRC parameter is not configured, the transmission circuitry is configured to perform frequency hopping for the PUSCH transmission based on the fourth RRC parameter set to interSlot or intraSlot.

[0026] A method for a user equipment (UE) is described. The method may comprise acquiring a first RRC parameter, a second RRC parameter, a third RRC parameter, and a fourth RRC parameter, and transmitting a PUSCH in multiple slots, performing frequency hopping for the PUSCH transmission based on the second RRC parameter set to interRepetition or interSlot in a case that the first RRC parameter is set to pusch- RepTypeB, performing frequency hopping for the PUSCH transmission based on the third RRC parameter set to interRepetition, interSlot, or intraSlot in a case that the first RRC parameter is set to pusch-RepTypeA, not performing frequency hopping for the PUSCH transmission in a case that the first RRC parameter is set to pusch-RepTypeB and the second RRC parameter is not configured, and performing frequency hopping for the PUSCH transmission based on the fourth RRC parameter set to interSlot or intraSlot in a case that the first RRC parameter is set to pusch-RepTypeA and the third RRC parameter is not configured.

For example, floor (CX) may be a function that provides the largest integer within a range that does not exceed the real number CX. ceil (DX) may be a ceiling function to a real number DX. For example, ceil (DX) may be a function that provides the smallest integer within the range not less than the real number DX. mod (EX, FX) may be a function that provides the remainder obtained by dividing EX by FX. mod (EX, FX) may be a function that provides a value which corresponds to the remainder of dividing EX by FX. It is exp (GX) = e ^A GX. Here, e is Napier number. (HX) ^A (IX) indicates IX to the power of HX.

[0028] In a wireless communication system according to one aspect of the present embodiment, at least OFDM (Orthogonal Frequency Division Multiplex) is used. An OFDM symbol is a unit of time domain of the OFDM. The OFDM symbol includes at least one or more subcarriers. An OFDM symbol is converted to a time-continuous signal in baseband signal generation. In downlink, at least CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Multiplex) is used. In uplink, either CP-OFDM or DFT-s-OFDM (Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplex) is used. DFT-s-OFDM may be given by applying transform precoding to CP-OFDM. CP-OFDM is OFDM using CP (Cyclic Prefix).

[0029] The OFDM symbol may be a designation including a CP added to the OFDM symbol. That is, an OFDM symbol may be configured to include the OFDM symbol and a CP added to the OFDM symbol.

[0030] Figure 1 is a conceptual diagram of a wireless communication system according to an aspect of the present embodiment. In Figure 1, the wireless communication system includes at least terminal device 1A to 1C and a base station device 3 (BS # 3: Base station # 3). Hereinafter, the terminal devices lA to 1C are also referred to as a terminal device 1 (UE # 1 : User Equipment # 1).

[0031] The base station device 3 may be configured to include one or more transmission devices (or transmission points, transmission devices, reception devices, transmission points, reception points). When the base station device 3 is configured by a plurality of transmission devices, each of the plurality of transmission devices may be arranged at a different position.

[0032] The base station device 3 may provide one or more serving cells. A serving cell may be defined as a set of resources used for wireless communication. A serving cell is also referred to as a cell.

[0033] A serving cell may be configured to include at least one downlink component carrier (downlink carrier) and/or one uplink component carrier (uplink carrier). A serving cell may be configured to include at least two or more downlink component carriers and/or two or more uplink component carriers. A downlink component carrier and an uplink component carrier are also referred to as component carriers (carriers).

[0034] For example, one resource grid may be provided for one component carrier. For example, one resource grid may be provided for one component carrier and a subcarrier-spacing configuration u. A subcarrier-spacing configuration u is also referred to as numerology. A resource grid includes N ^slze ’ ^u _{grid, x} N _RBsc subcarriers. The resource grid starts from a common resource block with index N ^{start, u} _grid . The common resource block with the index N ^{start, u} _grid is also referred to as a reference point of the resource grid. The resource grid includes N ^subframe ’ ^u _symb OFDM symbols. The subscript x indicates the transmission direction, and indicates either downlink or uplink. One resource grid is provided for an antenna port p, a subcarrier-spacing configuration u, and a transmission direction x.

[0035] Resource grid is also referred to as carrier.

[0036] N ^slze ’ ^u _grid,x and N ^start ’ ^u _grid are given based at least on an RRC parameter (e.g. referred to as RRC parameter CarrierBandwidth). The RRC parameter is used to define one or more SCS (SubCarrier- Spacing) specific carriers. One resource grid corresponds to one SCS specific carrier. One component carrier may comprise one or more SCS specific carriers. The SCS specific carrier may be included in a system information block (SIB). For each SCS specific carrier, a subcarrier-spacing configuration u may be provided.

[0037] Figure 2 is an example showing the relationship between subcarrier-spacing configuration u, the number of OFDM symbols per slot N ^slot symb, and the CP configuration according to an aspect of the present embodiment. In Figure 2A, for example, when the subcarrier-spacing configuration u is set to 2 and the CP configuration is set to normal CP (normal cyclic prefix), N ^slot _symb = 14, N ^frame ’ ^u _slot = 40, N ^subframe ’ ^u _slot = 4. Further, in Figure 2B, for example, when the subcarrier-spacing configuration u is set to 2 and the CP configuration is set to an extended CP (extended cyclic prefix), N ^slot _Symb = 12, N ^{frame, u} _slot = 40, N ^subframe ’ ^u _slot = 4.

[0038] In the wireless communication system according to an aspect of the present embodiment, a time unit T _c may be used to represent the length of the time domain. The time unit T _c is T _c = 1 / (df _max * Nf). It is df _max = 480 kHz. It is Nf = 4096. The constant k is k = df _max * Nf / (df _ref N _{f, ref} ) = 64. dfref is 15 kHz. Nf, ref is 2048.

[0039] Transmission of signals in the downlink and/or transmission of signals in the uplink may be organized into radio frames (system frames, frames) of length Tf. It is Tf = ( df _max N _f / 100) * T _s = 10 ms. One radio frame is configured to include ten subframes. The subframe length is T _sf = (df _max Nf / 1000) T _s = 1 ms. The number of OFDM symbols per subframe is N ^subframe , ^u _symb = N ^slot _symb N ^subframe , ^u _slot .

[0040] For a subcarrier-spacing configuration u, the number of slots included in a subframe and indexes may be given. For example, slot index n ^u _s may be given in ascending order with an integer value ranging from 0 to N ^subframe ’ ^u _slot -1 in a subframe. For subcarrier-spacing configuration u, the number of slots included in a radio frame and indexes of slots included in the radio frame may be given. Also, the slot index n ^u _s , f may be given in ascending order with an integer value ranging from 0 to N ^{frame, u} _slot -1 in the radio frame. Consecutive N ^slot _symb OFDM symbols may be included in one slot. It is N ^slot _symb = 14.

The horizontal axis in Figure 3 indicates frequency domain. Figure 3 shows a configuration example of a resource grid of subcarrier-spacing configuration u = u ₁ in the component carrier 300 and a configuration example of a resource grid of subcarrier-spacing configuration u = u ₂ in a component carrier. One or more subcarrier-spacing configuration may be set for a component carrier. Although it is assumed in Figure 3 that ui = u ₂ -1, various aspects of this embodiment are not limited to the condition of ui = u ₂ -1.

[0042] The component carrier 300 is a band having a predetermined width in the frequency domain.

[0043] Point (Point) 3000 is an identifier for identifying a subcarrier. Point 3000 is also referred to as point A. The common resource block (CRB: Common resource block) set 3100 is a set of common resource blocks for the subcarrier-spacing configuration ui. [0044] Among the common resource block-set 3100, the common resource block including the point 3000 (the block indicated by the upper right diagonal line in Figure 3) is also referred to as a reference point of the common resource block-set 3100. The reference point of the common resource block-set 3100 may be a common resource block with index 0 in the common resource block-set 3100.

[0045] The offset 3011 is an offset from the reference point of the common resource block-set 3100 to the reference point of the resource grid 3001. The offset 3011 is indicated by the number of common resource blocks which is relative to the subcarrierspacing configuration ui. The resource grid 3001 includes N ^{slze u} _grid1,x common resource blocks starting from the reference point of the resource grid 3001.

[0046] The offset 3013 is an offset from the reference point of the resource grid 3001 to the reference point (N ^{start ,u} _BWP,i1 ) of the BWP (Bandwidth Part) 3003 of the index il .

[0048] A common resource block including the point 3000 (a block indicated by a upper left diagonal line in Figure 3) in the common resource block-set 3200 is also referred to as a reference point of the common resource block-set 3200. The reference point of the common resource block-set 3200 may be a common resource block with index 0 in the common resource block-set 3200.

[0049] The offset 3012 is an offset from the reference point of the common resource block-set 3200 to the reference point of the resource grid 3002. The offset 3012 is indicated by the number of common resource blocks for subcarrier-spacing configuration u = u ₂ . The resource grid 3002 includes N ^slze ’ ^u _grid2,x common resource blocks starting from the reference point of the resource grid 3002. [0050] The offset 3014 is an offset from the reference point of the resource grid 3002 to the reference point (N ^{start ,u} _BWP,i2 ) of the BWP 3004 with index 12.

[0051] Figure 4 is a diagram showing a configuration example of a resource grid 3001 according to an aspect of the present embodiment. In the resource grid of Figure 4, the horizontal axis indicates OFDM symbol index 1 _sym , and the vertical axis indicates the subcarrier index k _sc . The resource grid 3001 includes N ^size ’ ^u _grid1 ,xN ^RB _S c subcarriers, and includes N ^subframes,u _symb OFDM symbols. A resource specified by the subcarrier index k _sc and the OFDM symbol index lsym in a resource grid is also referred to as a resource element (RE: Resource Element).

[0052] A resource block (RB: Resource Block) includes N^sc consecutive subcarriers. A resource block is a generic name of a common resource block, a physical resource block (PRB: Physical Resource Block), and a virtual resource block (VRB: Virtual Resource Block). It is N ^RB _sc = 12.

[0053] A resource block unit is a set of resources that corresponds to one OFDM symbol in one resource block. That is, one resource block unit includes 12 resource elements which corresponds to one OFDM symbol in one resource block.

[0054] Common resource blocks for a subcarrier-spacing configuration u are indexed in ascending order from 0 in the frequency domain in a common resource block-set. The common resource block with index 0 for the subcarrier-spacing configuration u includes (or collides with, matches) the point 3000. The index n ^u CRB of the common resource block with respect to the subcarrier-spacing configuration u satisfies the relationship of n ^u CRB = ceil (k _sc / N ^RB _SC ). The subcarrier with k _sc = 0 is a subcarrier with the same center frequency as the center frequency of the subcarrier which corresponds to the point 3000. [0055] Physical resource blocks for a subcarrier-spacing configuration u are indexed in ascending order from 0 in the frequency domain in a BWP. The index n ^u pRB of the physical resource block with respect to the subcarrier-spacing configuration u satisfies the relationship of n ^u CRB = n ^u PRB + N ^{start u} _BWP,i . The N ^{start u} _BWP, indicates the reference point of BWP with index i.

[0056] A BWP is defined as a subset of common resource blocks included in the resource grid. The BWP includes N ^slze ’ ^u Bwp,i common resource blocks starting from the reference points N ^{start u} _BWPi - A BWP for the downlink component carrier is also referred to as a downlink BWP. A BWP for the uplink component carrier is also referred to as an uplink BWP.

[0057] An antenna port is defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed. For example, the channel may correspond to a physical channel. For example, the symbols may correspond to OFDM symbols. For example, the symbols may correspond to resource block units. For example, the symbols may correspond to resource elements.

[0058] Two antenna ports are said to be QCL (Quasi Co-Located) if the large-scale properties of the channel over which a symbol on one antenna port is conveyed can be inferred from the channel over which a symbol on the other antenna port is conveyed. The large-scale properties include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters.

The configuration of the RF unit 32 included in the wireless transmission unit 30a and the configuration of the RF unit 32 included in the wireless reception unit 30b may be the same or different. The configuration of the antenna unit 31 included in the wireless transmission unit 30a and the configuration of the antenna unit 31 included in the wireless reception unit 30b may be the same or different.

[0062] The higher-layer processing unit 34 provides downlink data (a transport block) to the wireless transmission I reception unit 30 (or the wireless transmission unit 30a). The higher-layer processing unit 34 performs processing of a medium access control (MAC) layer, a packet data convergence protocol layer (PDCP layer), a radio link control layer (RLC layer) and/or an RRC layer.

[0063] The medium access control layer processing unit 35 included in the higher- layer processing unit 34 performs processing of the MAC layer.

[0064] The radio resource control layer processing unit 36 included in the higher- layer processing unit 34 performs the process of the RRC layer. The radio resource control layer processing unit 36 manages various configuration information / parameters (RRC parameters) of the terminal device 1. The radio resource control layer processing unit 36 configures an RRC parameter based on the RRC message received from the terminal device 1.

[0065] The wireless transmission / reception unit 30 (or the wireless transmission unit

30a) performs processing such as encoding and modulation. The wireless transmission / reception unit 30 (or the wireless transmission unit 30a) generates a physical signal by encoding and modulating the downlink data. The wireless transmission / reception unit 30 (or the wireless transmission unit 30a) converts OFDM symbols in the physical signal to a baseband signal by conversion to a time-continuous signal. The wireless transmission / reception unit 30 (or the wireless transmission unit 30a) transmits the baseband signal (or the physical signal) to the terminal device 1 via radio frequency. The wireless transmission / reception unit 30 (or the wireless transmission unit 30a) may arrange the baseband signal (or the physical signal) on a component carrier and transmit the baseband signal (or the physical signal) to the terminal device 1.

[0066] The wireless transmission I reception unit 30 (or the wireless reception unit 30b) performs processing such as demodulation and decoding. The wireless transmission / reception unit 30 (or the wireless reception unit 30b) separates, demodulates and decodes the received physical signal, and provides the decoded information to the higher-layer processing unit 34. The wireless transmission / reception unit 30 (or the wireless reception unit 30b) may perform the channel access procedure prior to the transmission of the physical signal.

[0067] The RF unit 32 demodulates the physical signal received via the antenna unit 31 into a baseband signal (down convert), and/or removes extra frequency components. The RF unit 32 provides the processed analog signal to the baseband unit 33.

[0068] The baseband unit 33 converts an analog signal (signals on radio frequency) input from the RF unit 32 into a digital signal (a baseband signal). The baseband unit 33 separates a portion which corresponds to CP (Cyclic Prefix) from the digital signal. The baseband unit 33 performs Fast Fourier Transformation (FFT) on the digital signal from which the CP has been removed. The baseband unit 33 provides the physical signal in the frequency domain.

[0069] The baseband unit 33 performs Inverse Fast Fourier Transformation (IFFT) on downlink data to generate an OFDM symbol, adds a CP to the generated OFDM symbol, generates a digital signal (baseband signal), and convert the digital signal into an analog signal. The baseband unit 33 provides the analog signal to the RF unit 32.

[0070] The RF unit 32 removes extra frequency components from the analog signal (signals on radio frequency) input from the baseband unit 33, up-converts the analog signal to a radio frequency, and transmits it via the antenna unit 31. The RF unit 32 may have a function of controlling transmission power. The RF unit 32 is also referred to as a transmission power control unit. [0071] At least one or more serving cells (or one or more component carriers, one or more downlink component carriers, one or more uplink component carriers) may be configured for the terminal device 1.

[0075] A SCell may be included in either a MCG or a SCG.

[0076] The serving cell group (cell group) is a designation including at least MCG and SCG. The serving cell group may include one or more serving cells (or one or more component carriers). One or more serving cells (or one or more component carriers) included in the serving cell group may be operated by carrier aggregation.

[0077] One or more downlink BWPs may be configured for each serving cell (or each downlink component carrier). One or more uplink BWPs may be configured for each serving cell (or each uplink component carrier).

[0078] Among the one or more downlink BWPs set for the serving cell (or the downlink component carrier), one downlink BWP may be set as an active downlink BWP (or one downlink BWP may be activated). Among the one or more uplink BWPs set for the serving cell (or the uplink component carrier), one uplink BWP may be set as an active uplink BWP (or one uplink BWP may be activated). [0079] A PDSCH, a PDCCH, and a CSI-RS may be received in the active downlink BWP. The terminal device 1 may receive the PDSCH, the PDCCH, and the CSI-RS in the active downlink BWP. A PUCCH and a PUSCH may be sent on the active uplink BWP. The terminal device 1 may transmit the PUCCH and the PUSCH in the active uplink BWP. The active downlink BWP and the active uplink BWP are also referred to as active BWP. [0080] The PDSCH, the PDCCH, and the CSI-RS may not be received in downlink BWPs (inactive downlink BWPs) other than the active downlink BWP. The terminal device 1 may not receive the PDSCH, the PDCCH, and the CSI-RS in the downlink BWPs which are other than the active downlink BWP. The PUCCH and the PUSCH do not need to be transmitted in uplink BWPs (inactive uplink BWPs) other than the active uplink BWP. The terminal device 1 may not transmit the PUCCH and the PUSCH in the uplink BWPs which is other than the active uplink BWP. The inactive downlink BWP and the inactive uplink BWP are also referred to as inactive BWP.

[0081] Downlink BWP switching deactivates an active downlink BWP and activates one of inactive downlink BWPs which are other than the active downlink BWP. The downlink BWP switching may be controlled by a BWP field included in a downlink control information. The downlink BWP switching may be controlled based on higher- layer parameters.

[0082] Uplink BWP switching is used to deactivate an active uplink BWP and activate any inactive uplink BWP which is other than the active uplink BWP. Uplink BWP switching may be controlled by a BWP field included in a downlink control information. The uplink BWP switching may be controlled based on higher-layer parameters. [0083] Among the one or more downlink BWPs set for the serving cell, two or more downlink BWPs may not be set as active downlink BWPs. For the serving cell, one downlink BWP may be active at a certain time.

[0084] Among the one or more uplink BWPs set for the serving cell, two or more uplink BWPs may not be set as active uplink BWPs. For the serving cell, one uplink BWP may be active at a certain time.

The wireless transmission I reception unit 10 (or the wireless transmission unit 10a) converts OFDM symbols in the physical signal to a baseband signal by conversion to a time-continuous signal. The wireless transmission / reception unit 10 (or the wireless transmission unit 10a) transmits the baseband signal (or the physical signal) to the base station device 3 via radio frequency. The wireless transmission / reception unit 10 (or the wireless transmission unit 10a) may arrange the baseband signal (or the physical signal) on a BWP (active uplink BWP) and transmit the baseband signal (or the physical signal) to the base station device 3.

The wireless transmission / reception unit 10 (or the wireless reception unit 10b) may receive a physical signal in a BWP (active downlink BWP) of a serving cell. The wireless transmission / reception unit

10 (or the wireless reception unit 10b) separates, demodulates and decodes the received physical signal, and provides the decoded information to the higher-layer processing unit 14. The wireless transmission I reception unit 10 (or the wireless reception unit 10b) may perform the channel access procedure prior to the transmission of the physical signal.

[0092] The RF unit 12 demodulates the physical signal received via the antenna unit

11 into a baseband signal (down convert), and/or removes extra frequency components. The RF unit 12 provides the processed analog signal to the baseband unit 13.

[0093] The baseband unit 13 converts an analog signal (signals on radio frequency) input from the RF unit 12 into a digital signal (a baseband signal). The baseband unit 13 separates a portion which corresponds to CP from the digital signal, performs fast Fourier transformation on the digital signal from which the CP has been removed, and provides the physical signal in the frequency domain.

[0094] The baseband unit 13 performs inverse fast Fourier transformation on uplink data to generate an OFDM symbol, adds a CP to the generated OFDM symbol, generates a digital signal (baseband signal), and convert the digital signal into an analog signal. The baseband unit 13 provides the analog signal to the RF unit 12.

[0095] The RF unit 12 removes extra frequency components from the analog signal (signals on radio frequency) input from the baseband unit 13, up-converts the analog signal to a radio frequency, and transmits it via the antenna unit 11 The RF unit 12 may have a function of controlling transmission power. The RF unit 12 is also referred to as a transmission power control unit.

[0096] Hereinafter, physical signals (signals) will be described.

[0097] Physical signal is a generic term for downlink physical channels, downlink physical signals, uplink physical channels, and uplink physical channels. The physical channel is a generic term for downlink physical channels and uplink physical channels.

[0098] An uplink physical channel may correspond to a set of resource elements that carry information originating from the higher-layer and/or uplink control information. The uplink physical channel may be a physical channel used in an uplink component carrier. The uplink physical channel may be transmitted by the terminal device 1.

[0165] A PDSCH may be used to transmit one or more transport blocks. A PDSCH may be used to transmit one or more transport blocks which corresponds to a DL-SCH. A PDSCH may be used to convey one or more transport blocks. A PDSCH may be used to convey one or more transport blocks which corresponds to a DL-SCH. One or more transport blocks may be arranged in a PDSCH. One or more transport blocks which corresponds to a DL-SCH may be arranged in a PDSCH. The base station device 3 may transmit a PDSCH. The terminal device 1 may receive the PDSCH.

[0166] Downlink physical signals may correspond to a set of resource elements. The downlink physical signals may not carry the information generated in the higher-layer. The downlink physical signals may be physical signals used in the downlink component carrier. A downlink physical signal may be transmitted by the base station device 3. The downlink physical signal may be transmitted by the terminal device 1. In the wireless communication system according to one aspect of the present embodiment, at least a part or all of an SS (Synchronization signal), DL DMRS (DownLink DeModulation Reference Signal), CSI-RS (Channel State Information-Reference Signal), and DL PTRS (DownLink Phase Tracking Reference Signal) may be used.

[0167] The synchronization signal may be used at least for the terminal device 1 to synchronize in the frequency domain and/or time domain for downlink. The synchronization signal is a generic name of PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal).

[0168] Figure 7 is a diagram showing a configuration example of an SS/PBCH block according to an aspect of the present embodiment. In Figure 7, the horizontal axis indicates time domain (OFDM symbol index 1 _sym ), and the vertical axis indicates frequency domain. The shaded blocks indicate a set of resource elements for a PSS. The blocks of grid lines indicate a set of resource elements for an SSS. Also, the blocks in the horizontal line indicate a set of resource elements for a PBCH and a set of resource elements for a DMRS for the PBCH (DMRS related to the PBCH, DMRS included in the PBCH, DMRS which corresponds to the PBCH).

[0169] As shown in Figure 7, the SS/PBCH block includes a PSS, an SSS, and a PBCH. The SS/PBCH block includes 4 consecutive OFDM symbols. The SS/PBCH block includes 240 subcarriers. The PSS is allocated to the 57th to 183rd subcarriers in the first OFDM symbol. The SSS is allocated to the 57th to 183rd subcarriers in the third OFDM symbol. The first to 56th subcarriers of the first OFDM symbol may be set to zero. The 184th to 240th subcarriers of the first OFDM symbol may be set to zero. The 49th to 56th subcarriers of the third OFDM symbol may be set to zero. The 184th to 192nd subcarriers of the third OFDM symbol may be set to zero. In the first to 240th subcarriers of the second OFDM symbol, the PBCH is allocated to subcarriers in which the DMRS for the PBCH is not allocated. In the first to 48th subcarriers of the third OFDM symbol, the PBCH is allocated to subcarriers in which the DMRS for the PBCH is not allocated. In the 193rd to 240th subcarriers of the third OFDM symbol, the PBCH is allocated to subcarriers in which the DMRS for the PBCH is not allocated. In the first to 240th subcarriers of the 4th OFDM symbol, the PBCH is allocated to subcarriers in which the DMRS for the PBCH is not allocated.

[0170] The antenna ports of a PSS, an SSS, a PBCH, and a DMRS for the PBCH in an SS/PBCH block may be identical.

[0171] A PBCH may be estimated from a DMRS for the PBCH .For the DM-RS for the PBCH, the channel over which a symbol for the PBCH on an antenna port is conveyed can be inferred from the channel over which another symbol for the DM-RS on the antenna port is conveyed only if the two symbols are within a SS/PBCH block transmitted within the same slot, and with the same SS/PBCH block index.

[0172] DL DMRS is a generic name of DMRS for a PBCH, DMRS for a PDSCH, and DMRS for a PDCCH.

[0173] A set of antenna ports for a DMRS for a PDSCH (a DMRS associated with a

PDSCH, a DMRS included in a PDSCH, a DMRS which corresponds to a PDSCH) may be given based on the set of antenna ports for the PDSCH. The set of antenna ports for the DMRS for the PDSCH may be the same as the set of antenna ports for the PDSCH. [0174] Transmission of a PDSCH and transmission of a DMRS for the PDSCH may be indicated (or scheduled) by one DCI format. The PDSCH and the DMRS for the PDSCH may be collectively referred to as PDSCH. Transmitting a PDSCH may be transmitting a PDSCH and a DMRS for the PDSCH.

[0175] A PDSCH may be estimated from a DMRS for the PDSCH. For a DM-RS associated with a PDSCH, the channel over which a symbol for the PDSCH on one antenna port is conveyed can be inferred from the channel over which another symbol for the DM-RS on the antenna port is conveyed only if the two symbols are within the same resource as the scheduled PDSCH, in the same slot, and in the same PRG (Precoding Resource Group).

[0176] Antenna ports for a DMRS for a PDCCH (a DMRS associated with a PDCCH, a DMRS included in a PDCCH, a DMRS which corresponds to a PDCCH) may be the same as an antenna port for the PDCCH.

[0177] A PDCCH may be estimated from a DMRS for the PDCCH. For a DM-RS associated with a PDCCH, the channel over which a symbol for the PDCCH on one antenna port is conveyed can be inferred from the channel over which another symbol for the DM-RS on the same antenna port is conveyed only if the two symbols are within resources for which the UE may assume the same precoding being used (i.e. within resources in a REG bundle).

[0178] A BCH (Broadcast CHannel), a UL-SCH (Uplink-Shared CHannel) and a DL- SCH (Downlink-Shared CHannel) are transport channels. A channel used in the MAC layer is called a transport channel. A unit of transport channel used in the MAC layer is also called transport block (TB) or MAC PDU (Protocol Data Unit). In the MAC layer, control of HARQ (Hybrid Automatic Repeat request) is performed for each transport block. The transport block is a unit of data delivered by the MAC layer to the physical layer. In the physical layer, transport blocks are mapped to codewords and modulation processing is performed for each codeword.

[0179] One UL-SCH and one DL-SCH may be provided for each serving cell. BCH may be given to PCell. BCH may not be given to PSCell and SCell.

[0180] ABCCH (Broadcast Control CHannel), a CCCH (Common Control CHannel), and a DCCH (Dedicated Control CHannel) are logical channels. The BCCH is a channel of the RRC layer used to deliver MIB or system information. The CCCH may be used to transmit a common RRC message in a plurality of terminal devices 1. The CCCH may be used for the terminal device 1 which is not connected by RRC. The DCCH may be used at least to transmit a dedicated RRC message to the terminal device 1. The DCCH may be used for the terminal device 1 that is in RRC-connected mode.

[0181] The RRC message includes one or more RRC parameters (information elements, higher layer parameters). For example, the RRC message may include a MIB. For example, the RRC message may include system information (SIB: System Information Block, MIB). SIB is a generic name for various type of SIBs (e.g., SIB1, SIB2). For example, the RRC message may include a message which corresponds to a CCCH. For example, the RRC message may include a message which corresponds to a DCCH. RRC message is a general term for common RRC message and dedicated RRC message.

[0182] The BCCH in the logical channel may be mapped to the BCH or the DL-SCH in the transport channel. The CCCH in the logical channel may be mapped to the DL- SCH or the UL-SCH in the transport channel. The DCCH in the logical channel may be mapped to the DL-SCH or the UL-SCH in the transport channel. [0183] The UL-SCH in the transport channel may be mapped to a PUSCH in the physical channel. The DL-SCH in the transport channel may be mapped to a PDSCH in the physical channel. The BCH in the transport channel may be mapped to a PBCH in the physical channel.

[0184] A higher-layer parameter is a parameter included in an RRC message or a MAC CE (Medium Access Control Control Element). The higher-layer parameter is a generic name of information included in a MIB, system information, a message which corresponds to CCCH, a message which corresponds to DCCH, and a MAC CE. A higher- layer parameter may be referred to as an RRC parameter or an RRC configuration if the higher-layer parameter is the parameter included in the RRC message.

[0185] A higher-layer parameter may be a cell-specific parameter or a UE-specific parameter. A cell-specific parameter is a parameter including a common configuration in a cell. A UE-specific parameter is a parameter including a configuration that may be configured differently for each UE.

[0186] The base station device may indicate change of cell-specific parameters by reconfiguration with random-access. The UE may change cell-specific parameters before triggering random-access. The base station device may indicate change of UE-specific parameters by reconfiguration with or without random-access. The UE may change UE- specific parameters before or after random-access.

[0187] The procedure performed by the terminal device 1 includes at least a part or all of the following 5Ato 5C. The 5A is cell search. The 5B is random-access. The 5C is data communication.

[0188] The cell search is a procedure used by the terminal device 1 to synchronize with a cell in the time domain and/or the frequency domain and to detect a physical cell identity. The terminal device 1 may detect the physical cell ID by performing synchronization of time domain and/or frequency domain with a cell by the cell search.

[0189] A sequence of a PSS is given based at least on a physical cell ID. A sequence of an SSS is given based at least on the physical cell ID.

[0190] An SS/PBCH block candidate indicates a resource for which transmission of the SS/PBCH block may exist. An SS/PBCH block may be transmitted at a resource indicated as the SS/PBCH block candidate. The base station device 3 may transmit an SS/PBCH block at an SS/PBCH block candidate. The terminal device 1 may receive (detect) the SS/PBCH block at the SS/PBCH block candidate.

[0191] A set of SS/PBCH block candidates in a half radio frame is also referred to as an SS-burst-set. The SS-burst-set is also referred to as a transmission window, a SS transmission window, or a DRS transmission window (Discovery Reference Signal transmission window). The SS-burst-set is a generic name that includes at least a first SS- burst-set and a second SS-burst-set.

[0192] The base station device 3 transmits SS/PBCH blocks of one or more indexes at a predetermined cycle. The terminal device 1 may detect an SS/PBCH block of at least one of the SS/PBCH blocks of the one or more indexes. The terminal device 1 may attempt to decode the PBCH included in the SS/PBCH block.

[0193] The random-access is a procedure including at least a part or all of message 1 , message 2, message 3, and message 4.

[0194] The message 1 is a procedure in which the terminal device 1 transmits a PRACH. The terminal device 1 transmits the PRACH in one PRACH occasion selected from among one or more PRACH occasions based on at least the index of the SS/PBCH block candidate detected based on the cell search. [0195] The message 2 is a procedure in which the terminal device 1 attempts to detect a DCI format 1_0 with CRC (Cyclic Redundancy Check) scrambled by an RA-RNTI (Random Access-Radio Network Temporary Identifier). The terminal device 1 may attempt to detect the DCI format 1_0 in a search-space-set.

[0196] The message 3 is a procedure for transmitting a PUSCH scheduled by a random-access response grant included in the DCI format 1_0 detected in the message 2 procedure. The random-access response grant is indicated by the MAC CE included in the PDSCH scheduled by the DCI format 1_0 .

[0197] The PUSCH scheduled based on the random-access response grant is either a message 3 PUSCH or a PUSCH. The message 3 PUSCH contains a contention resolution identifier MAC CE. The contention resolution ID MAC CE includes a contention resolution ID.

[0198] Retransmission of the message 3 PUSCH is scheduled by DCI format 0_0 with CRC scrambled by a TC-RNTI (Temporary Cell-Radio Network Temporary Identifier).

[0199] The message 4 is a procedure that attempts to detect a DCI format 1_0 with CRC scrambled by either a C-RNTI (Cell-Radio Network Temporary Identifier) or a TC- RNTI. The terminal device 1 receives a PDSCH scheduled based on the DCI format 1_0 . The PDSCH may include a collision resolution ID.

[0200] Data communication is a generic term for downlink communication and uplink communication.

[0201] In data communication, the terminal device 1 attempts to detect a PDCCH (attempts to monitor a PDCCH, monitors a PDCCH). in a resource identified at least based on one or all of a control resource set and a search-space-set. It’s also called as “the terminal device 1 attempts to detect a PDCCH in a control resource set”, “the terminal device 1 attempts to detect a PDCCH in a search-space-set”, “the terminal device 1 attempts to detect a PDCCH candidate in a control resource set”, “the terminal device 1 attempts to detect a PDCCH candidate in a search-space-set”, “the terminal device 1 attempts to detect a DCI format in a control resource set”, or “the terminal device 1 attempts to detect a DCI format in a search-space-set”. Monitoring a PDCCH may be equivalent as monitoring a DCI format in the PDCCH.

[0202] The control resource set is a set of resources configured by the number of resource blocks and a predetermined number of OFDM symbols in a slot.

[0203] The set of resources for the control resource set may be indicated by higher- layer parameters. The number of OFDM symbols included in the control resource set may be indicated by higher-layer parameters.

[0204] A PDCCH may be also called as a PDCCH candidate.

[0205] A search-space-set is defined as a set of PDCCH candidates. A search-space- set may be a Common Search Space (CSS) set or a UE-specific Search Space (USS) set. [0206] The CSS set is a generic name of a type-0 PDCCH common search-space-set, a type-Oa PDCCH common search-space-set, a type-1 PDCCH common search-space-set, a type-2 PDCCH common search-space-set, and a type-3 PDCCH common search-space- set. The USS set may be also called as UE-specific PDCCH search-space-set.

[0207] The type-0 PDCCH common search-space-set may be used as a common search-space-set with index 0. The type-0 PDCCH common search-space-set may be an common search-space-set with index 0. [0208] A search-space-set is associated with (included in, corresponding to) a control resource set. The index of the control resource set associated with the search-space-set may be indicated by higher-layer parameters.

[0209] For a search-space-set, a part or all of 6 A to 6C may be indicated at least by higher-layer parameters. The 6A is PDCCH monitoring period. The 6B is PDCCH monitoring pattern within a slot. The 6C is PDCCH monitoring offset.

[0210] A monitoring occasion of a search-space-set may correspond to one or more OFDM symbols in which the first OFDM symbol of the control resource set associated with the search-space-set is allocated. A monitoring occasion of a search-space-set may correspond to resources identified by the first OFDM symbol of the control resource set associated with the search-space-set. A monitoring occasion of a search-space-set is given based at least on a part or all of PDCCH monitoring periodicity, PDCCH monitoring pattern within a slot, and PDCCH monitoring offset.

[0211] Figure 8 is a diagram showing an example of the monitoring occasion of the search-space-set according to an aspect of the present embodiment. In Figure 8, the search-space-set 91 and the search-space-set 92 are sets in the primary cell 301, the search-space-set 93 is a set in the secondary cell 302, and the search-space-set 94 is a set in the secondary cell 303.

[0212] In Figure 8, the block indicated by the grid line indicates the search-space-set 91, the block indicated by the upper right diagonal line indicates the search-space-set 92, the block indicated by the upper left diagonal line indicates the search-space-set 93, and the block indicated by the horizontal line indicates the search-space-set 94.

[0213] In Figure 8, the PDCCH monitoring periodicity for the search-space-set 91 is set to 1 slot, the PDCCH monitoring offset for the search-space-set 91 is set to 0 slot, and the PDCCH monitoring pattern for the search-space-set 91 is [1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0]. That is, the monitoring occasion of the search-space-set 91 corresponds to the first OFDM symbol (OFDM symbol # 0) and the eighth OFDM symbol (OFDM symbol # 7) in each of the slots.

[0214] In Figure 8, the PDCCH monitoring periodicity for the search-space-set 92 is set to 2 slots, the PDCCH monitoring offset for the search-space-set 92 is set to 0 slots, and the PDCCH monitoring pattern for the search-space-set 92 is [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]. That is, the monitoring occasion of the search-space-set 92 corresponds to the leading OFDM symbol (OFDM symbol # 0) in each of the even slots.

[0215] In Figure 8, the PDCCH monitoring periodicity for the search-space-set 93 is set to 2 slots, the PDCCH monitoring offset for the search-space-set 93 is set to 0 slots, and the PDCCH monitoring pattern for the search-space-set 93 is [0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0]. That is, the monitoring occasion of the search-space-set 93 corresponds to the eighth OFDM symbol (OFDM symbol # 8) in each of the even slots.

[0216] In Figure 8, the PDCCH monitoring periodicity for the search-space-set 94 is set to 2 slots, the PDCCH monitoring offset for the search-space-set 94 is set to 1 slot, and the PDCCH monitoring pattern for the search-space-set 94 is [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]. That is, the monitoring occasion of the search-space-set 94 corresponds to the leading OFDM symbol (OFDM symbol # 0) in each of the odd slots.

[0217] The type-0 PDCCH common search-space-set may be at least used for a DCI format with a cyclic redundancy check (CRC) sequence scrambled by an SI-RNTI (System Information-Radio Network Temporary Identifier).

[0218] The type-Oa PDCCH common search-space-set may be used at least for a DCI format with a cyclic redundancy check sequence scrambled by an SI-RNTI. [0219] The type-1 PDCCH common search-space-set may be used at least for a DCI format with a CRC sequence scrambled by an RA-RNTI (Random Access-Radio Network Temporary Identifier) or a CRC sequence scrambled by a TC-RNTI (Temporary Cell-Radio Network Temporary Identifier).

[0220] The type-2 PDCCH common search-space-set may be used for a DCI format with a CRC sequence scrambled by P-RNTI (Paging-Radio Network Temporary Identifier).

[0221] The type-3 PDCCH common search-space-set may be used for a DCI format with a CRC sequence scrambled by a C-RNTI (Cell-Radio Network Temporary Identifier).

[0222] The UE-specific search-space-set may be used at least for a DCI format with a CRC sequence scrambled by a C-RNTI.

[0223] In downlink communication, the terminal device 1 may detect a downlink DCI format. The detected downlink DCI format is at least used for resource assignment for a PDSCH. The detected downlink DCI format is also referred to as downlink assignment. The terminal device 1 attempts to receive the PDSCH. Based on a PUCCH resource indicated based on the detected downlink DCI format, an HARQ-ACK corresponding to the PDSCH (HARQ-ACK corresponding to a transport block included in the PDSCH) may be reported to the base station device 3.

[0224] In uplink communication, the terminal device 1 may detect an uplink DCI format. The detected uplink DCI format is at least used for resource assignment for a PUSCH. The detected uplink DCI format is also referred to as uplink grant. The terminal device 1 transmits the PUSCH. [0225] PUSCH transmission(s) can be dynamically scheduled by an UL grant in a DCI, or the transmission can correspond to a configured grant Type 1 or Type 2. The configured grant Type 1 PUSCH transmission is semi-statically configured to operate upon the reception of higher layer parameter of configuredGrantConfig including rrc- ConfiguredUplinkGrant without the detection of an UL grant in a DCI. The configured grant Type 2 PUSCH transmission is semi-persistently scheduled by an UL grant in a valid activation DCI according to those procedure(s) after the reception of higher layer parameter configuredGrantConfig not including rrc-ConfiguredUplinkGrant. If configuredGrantConfigToAddModList is configured, more than one configured grant configuration of configured grant Type 1 and/or configured grant Type 2 may be active at the same time on an active BWP of a serving cell.

[0226] More details of resource allocation in time domain for PUSCH scheduled by a DCI format is described. When the UE (terminal device 1) is scheduled to transmit a transport block and no CSI report, or the UE is scheduled to transmit a transport block and a CSI report(s) on PUSCH by a DCI, the 'Time domain resource assignment' field value m of the DCI may provide a row index m + 1 to an allocated table. The determination of the used resource allocation table may be pre-defined and/or defined in RRC configuration. The indexed row of the resource allocation table may define the slot offset K2, the start and length indicator SLIV, or directly the start symbol S and the allocation length L, the PUSCH mapping type, and the number of repetitions (if RRC parameter numberOfRepetitions is present in the resource allocation table) to be applied in the PUSCH transmission. It is noted that RRC parameter is a kind of high-layer parameter. [0227] For PUSCH scheduled by DCI format 0_1, if RRC parameter pusch- RepTypeIndicatorDCI-0-1 is set to 'pusch-RepTypeB', the UE may apply PUSCH repetition Type B procedure when determining the time domain resource allocation. For PUSCH scheduled by DCI format 0 2, if RRC parameter pusch-RepTypelndicatorDCI- 0-2 is set to 'pusch-RepTypeB', the UE may apply PUSCH repetition Type B procedure when determining the time domain resource allocation. Otherwise, the UE may apply PUSCH repetition Type A procedure when determining the time domain resource allocation for PUSCH scheduled by PDCCH.

[0228] For PUSCH repetition Type A, the starting symbol S relative to the start of the slot, and the number of consecutive symbols L counting from the symbol S allocated for the PUSCH may be determined from the start and length indicator SLIV of the indexed row: if (L-1) < 7 then SLIV = 14(L-1)+S, otherwise SLIV=14(14-L+1+(14-1-S), where 0<L<14-S.

[0229] For PUSCH repetition Type A, when transmitting PUSCH scheduled by DCI format 0_1 or 0 2 in PDCCH with CRC scrambled with C-RNTI, MCS-C-RNTI, or CS- RNTI with NDI=1, the number of repetitions K may be determined as: if RRC parameter numberOfRepetitions is present in the resource allocation table, the number of repetitions K may be equal to numberOfRepetitions; elseif the UE is configured with RRC parameter pusch-AggregationF actor, the number of repetitions K may be equal to pusch- AggregationFactor; otherwise K=1.

[0230] If the UE is not capable of a certain coverage enhancement feature(s) (e.g. available slot based PUSCH repetition counting) or if the UE is not provided with a certain coverage enhancement configuration(s) (e.g. available slot based PUSCH repetition counting), the following may be applied. For PUSCH repetition Type A, in case K>1, the same symbol allocation may be applied across the K consecutive slots and the PUSCH may be limited to a single transmission layer. The UE may repeat the TB across the K consecutive slots applying the same symbol allocation in each slot. The redundancy version to be applied on the nth transmission occasion of the TB, where n = 0, 1 , ... K-l , may be determined as describe below. For PUSCH repetition Type A, a PUSCH transmission in a slot of a multi-slot PUSCH transmission may be omitted according to the conditions at least and/or at most in, PUSCH-priority based procedure, slot configuration based procedure, slot format based procedure and cancellation indication based procedure. For example, a slot may be determined as available if the slot is available according to all the conditions defined in those procedures, and/or the slot may be determined as not available if the slot is not available according to at least one of the conditions defined in those procedures. K may be an integer.

[0231] If the UE is capable of a certain coverage enhancement feature(s) and/or if the UE is provided with a certain coverage enhancement configuration(s), the following may be applied. For PUSCH repetition Type A, in case K>1, the same symbol allocation may be applied across the K available slots (i.e. the first K slots which are available for the PUSCH transmission) and the PUSCH may be limited to a single transmission layer. The UE may repeat the TB across the K consecutive slots applying the same symbol allocation in each slot. The K available slots may be determined according to the conditions at least and/or at most in, PUSCH-priority based procedure, slot configuration based procedure, slot format based procedure and cancellation indication based procedure. For example, a slot may be determined as available if the slot is available according to all the conditions defined in those procedures, and/or the slot may be determined as not available if the slot is not available according to at least one of the conditions defined in those procedures. [0232] If the UE is capable of a certain coverage enhancement feature(s) and/or if the UE is provided with a certain coverage enhancement configuration(s), the following may be applied. For PUSCH repetition Type A, in case K>1, the same symbol allocation may be applied across the K available slots (i.e. the first K slots which are available for the PUSCH transmission) and the PUSCH may be limited to a single transmission layer. The UE may repeat the TB across the K available slots applying the same symbol allocation in each slot. The K available slots may be determined according to the conditions at least and/or at most in first RRC parameters. The first RRC parameters may be one or more of tdd-UL-DL-ConfigurationCommon, tdd-UL-DL-ConfigurationDedicated, ssb- PositionsInBurst, numberOfRepetitions, BandCombination-UplinkTxSwitch, repK, repK-RV, pusch-AggregationFactor, nrofSlots, configuredGrantConfig, cg-nrofSlots, cg- nrofPUSCH-InSlot, timeDomainAllocation, numberOflnvalidSymbolsForDL-UL- Switching, invalidSymbolPattem, and periodicityAndPattem. For PUSCH repetition Type A, a PUSCH transmission in a slot of a multi-slot PUSCH transmission is omitted according to the conditions at least and/or at most in second RRC parameters. The second RRC parameters may be one or more of tdd-UL-DL-ConfigurationCommon, tdd-UL-DL- ConfigurationDedicated, ssb-PositionsInBurst, numberOfRepetitions,

BandCombination-UplinkTxSwitch, repK, repK-RV, pusch-AggregationFactor, nrofSlots, configuredGrantConfig, cg-nrofSlots, cg-nrofPUSCH-InSlot, timeDomainAllocation, numberOflnvalidSymbolsForDL-UL-Switching, invalidSymbolPattem, and periodicityAndPattem.

[0233] The configuredGrantConfig may be referred to the ConfiguredGrantConfig. [0234] The configuredGrantConfig may be referred to as the ConfiguredGrantConfig. [0235] When PUSCH resource allocation is semi-statically configured by higher layer parameter configuredGrantConfig in BWP-UplinkDedicated information element, and the PUSCH transmission corresponding to a configured grant, the following higher layer parameters are applied in the transmission.

[0236] For Type 1 PUSCH transmissions with a configured grant, the following parameters are given in configuredGrantConfig unless mentioned otherwise, and For the determination of the PUSCH repetition type, if the higher layer parameter pusch- RepTypelndicator in rrc-ConfiguredUplinkGrant is configured and set to 'pusch- RepTypeB', PUSCH repetition type B is applied. Otherwise, PUSCH repetition type A is applied.

[0237] The higher layer parameter pusch-RepTypelndicator indicates whether UE follows the behavior for PUSCH repetition type A or the behavior for PUSCH repetition type B for each Type 1 configured grant configuration. The value pusch-RepTypeA enables the 'PUSCH repetition type A' and the value pusch-RepTypeB enables the 'PUSCH repetition type B'. The value pusch-RepTypeB is not configured simultaneously with cg-nrofPUSCH-InSlot-rl6 and cg-nrofSlots-rl6.

[0238] For PUSCH repetition type A, the selection of the time domain resource allocation table follows the rules for DCI format 0_0 on UE specific search space.

[0239] For PUSCH repetition type A, the selection of the time domain resource allocation table is as follows. If pusch-RepTypelndicatorDCI-O-l in pusch-Config is configured and set to 'pusch-RepTypeA', pusch- TimeDomainResourceAllocationListDCI-0-1 in pusch-Config is used. Otherwise, pusch- TimeDomainResourceAllocationListDCI-0-2 in pusch-Config is used. It is not expected that pusch-RepTypelndicator in rrc-ConfiguredUplinkGrant is configured with 'pusch- RepTypeA' when none of pusch-RepTypelndicatorDCI-O-l and pusch- RepTypeIndicatorDCI-0-2 in pusch-Config is set to 'pusch-RepTypeA'.

[0240] For PUSCH repetition type B, the selection of the time domain resource allocation table is as follows. If pusch-RepTypelndicatorDCI-O-l in pusch-Config is configured and set to 'pusch-RepTypeB', pusch- TimeDomainResourceAllocationListDCI-0-1 in pusch-Config is used. Otherwise, pusch- TimeDomainResourceAllocationListDCI-0-2 in pusch-Config is used. It is not expected that pusch-RepTypelndicator in rrc-ConfiguredUplinkGrant is configured with 'pusch- RepTypeB' when none of pusch-RepTypelndicatorDCI-O-l and pusch- RepTypeIndicatorDCI-0-2 in pusch-Config is set to 'pusch-RepTypeB'.

[0241] More details of resource allocation in time domain for PUSCH with configured grant is described. For PUSCH transmissions with a Type 1 or Type 2 configured grant, the number of (nominal) repetitions K to be applied to the transmitted transport block may be provided by the indexed row in the time domain resource allocation table if numberOfRepetitions is present in the table; otherwise K may be provided by the higher layer configured parameters repK. The UE may not be allowed to transmit anything on the resources configured by RRC parameter configuredGrantConfig if the higher layers did not deliver a transport block to transmit on the resources allocated for uplink transmission without grant.

[0242] A set of allowed periodicities P are defined in RRC configuration. The RRC parameter cg-nrofSlots, may provide the number of consecutive slots allocated within a configured grant period. The RRC parameter cg-nrofPUSCH-InSlot may provide the number of consecutive PUSCH allocations within a slot, where the first PUSCH allocation may follow the RRC parameter timeDomainAllocation for Type 1 PUSCH transmission or the higher layer configuration according to MAC procedure, and UL grant received on the DCI for Type 2 PUSCH transmissions, and the remaining PUSCH allocations may have the same length and PUSCH mapping type, and may be appended following the previous allocations without any gaps. The same combination of start symbol and length and PUSCH mapping type may repeat over the consecutively allocated slots.

[0243] The UE may not be expected to be configured with the time duration for the transmission of K repetitions larger than the time duration derived by the periodicity P. If the UE determines that, for a transmission occasion, the number of symbols available for the PUSCH transmission in a slot is smaller than transmission duration L, the UE may not transmit the PUSCH in the transmission occasion.

[0244] The procedures apply to PUSCH transmissions of PUSCH repetition Type A with a Type 1 or Type 2 configured grant. The RRC parameter repK-RV defines the redundancy version pattern to be applied to the repetitions. If cg-RetransmissionTimer is provided, the redundancy version for uplink transmission with a configured grant is determined by the UE. If the parameter repK-RV is not provided in the configuredGrantConfig and cg-RetransmissionTimer is not provided, the redundancy version for uplink transmissions with a configured grant shall be set to 0. If the parameter repK-RV is provided in the configuredGrantConfig and cg-RetransmissionTimer is not provided, for the nth transmission occasion among K repetitions, n=l, 2, ..., K, it is associated with (mod(n-l,4)+l) ^th value in the configured RV sequence. If a configured grant configuration is configured with startingFromRVO set to 'off, the initial transmission of a transport block may only start at the first transmission occasion of the K repetitions. Otherwise, the initial transmission of a transport block may start the first transmission occasion of the K repetitions if the configured RV sequence is {0,2,3, 1 } , any of the transmission occasions of the K repetitions that are associated with RV=0 if the configured RV sequence is {0,3,0,3}, and/or any of the transmission occasions of the K repetitions if the configured RV sequence is {0,0, 0,0}, except the last transmission occasion when K>8.

[0245] For any RV sequence, the repetitions shall be terminated after transmitting K repetitions, or at the last transmission occasion among the K repetitions within the period P, or from the starting symbol of the repetition that overlaps with a PUSCH with the same HARQ process scheduled by DCI format 0_0, 0_1 or 0 2, whichever is reached first. In addition, the UE shall terminate the repetition of a transport block in a PUSCH transmission if the UE receives a DCI format 0_1 with DFI flag provided and set to '1', and if in this DCI the UE detects ACK for the HARQ process corresponding to that transport block.

[0246] The UE is not expected to be configured with the time duration for the transmission of K repetitions larger than the time duration derived by the periodicity P. If the UE determines that, for a transmission occasion, the number of symbols available for the PUSCH transmission in a slot is smaller than transmission duration L, the UE does not transmit the PUSCH in the transmission occasion.

[0247] For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when K > 1, the UE shall repeat the TB across the K consecutive slots applying the same symbol allocation in each slot, except if the UE is provided with RRC parameters cg- nrofSlots and cg-nrofPUSCH-InSlot, in which case the UE repeats the TB in the repK earliest consecutive transmission occasion candidates within the same configuration. A Type 1 or Type 2 PUSCH transmission with a configured grant in a slot is omitted according to the conditions in one or more RRC configurations.

[0248] The procedures apply to PUSCH transmissions of PUSCH repetition type B with a Type 1 or Type 2 configured grant. For PUSCH transmissions with a Type 1 or Type 2 configured grant, the nominal repetitions and the actual repetitions are determined according to the procedures for PUSCH repetition Type B according to at least one of defined in those procedures. The higher layer configured parameters repK-RV defines the redundancy version pattern to be applied to the repetitions. If the parameter repK-RV is not provided in the configuredGrantConfig, the redundancy version for each actual repetition with a configured grant shall be set to 0. Otherwise, for the nth transmission occasion among all the actual repetitions (including the actual repetitions that are omitted) of the K nominal repetitions, it is associated with (mod(n- 1 ,4)+ 1 ) ^th value in the configured RV sequence. If a configured grant configuration is configured with startingFromRVO set to 'off, the initial transmission of a transport block may only start at the first transmission occasion of the actual repetitions. Otherwise, the initial transmission of a transport block may start at the first transmission occasion of the actual repetitions if the configured RV sequence is {0,2,3, 1 } , any of the transmission occasions of the actual repetitions that are associated with RV=0 if the configured RV sequence is {0,3, 0,3}, and/or any of the transmission occasions of the actual repetitions if the configured RV sequence is {0,0, 0,0}, except the actual repetitions within the last nominal repetition when K>8.

[0249] For any RV sequence, the repetitions shall be terminated after transmitting K nominal repetitions, or at the last transmission occasion among the K nominal repetitions within the period P, or from the starting symbol of a repetition that overlaps with a PUSCH with the same HARQ process scheduled by DCI format 0_0, 0_1 or 0 2, whichever is reached first. The UE is not expected to be configured with the time duration for the transmission of K nominal repetitions larger than the time duration derived by the periodicity P.

[0250] For PUSCH repetition Type A (as determined according to procedures defined in those procedures for scheduled PUSCH, or those procedures for configured PUSCH), a UE is configured for frequency hopping by the RRC parameter frequencyHoppingDCI- 0-1 (e.g. frequencyHoppingDCI-0-l-rl6 and/or frequencyHoppingDCI-0-l-rl7) in pusch-Config for PUSCH transmission scheduled by DCI format 0_1, and frequencyHoppingDCI-0-2 in pusch-Config for PUSCH transmission scheduled by DCI format 0 2, and by frequencyHopping provided in pusch-Config for PUSCH transmission scheduled by a DCI format other than 0 2, and by frequencyHopping provided in configuredGrantConfig for configured PUSCH transmission, and by frequencyHoppingPUSCH-RepTypeA provided in rrc-ConfiguredUplinkGrant for Type 1 configured PUSCH transmission. One of two frequency hopping modes (intra-slot frequency hopping, applicable to single slot and multi-slot PUSCH transmission and inter-slot frequency hopping, applicable to multi-slot PUSCH transmission) can be configured. One frequency hopping mode can be further configured (inter-repetition frequency hopping, applicable to multi-slot PUSCH transmission).

[0251] The pusch-Config may be referred to the PUSCH-Config.

[0252] The pusch-Config may be referred to as the PUSCH-Config.

[0253] The RRC parameter frequencyHopping indicates that the value intraSlot enables 'Intra-slot frequency hopping' and the value interSlot enables 'Inter-slot frequency hopping'. If the field is absent, frequency hopping is not configured for 'pusch-RepTypeA'. The field frequencyHopping applies to DCI format 0_0 and 0_1 for 'pusch-RepTypeA'. [0254] The RRC parameter frequencyHoppingDCI-0-l-rl6 indicates the frequency hopping scheme for DCI format 0_1 when pusch-RepTypelndicatorDCI-O-l is set to 'pusch-RepTypeB', The value interRepetition enables 'Inter-repetition frequency hopping', and the value interSlot enables 'Inter-slot frequency hopping'. If the field is absent, frequency hopping is not configured for DCI format 0_1.

[0255] The RRC parameter frequencyHoppingDCI-0-l-rl7 indicates the frequency hopping scheme for DCI format 0_1 when pusch-RepTypelndicatorDCI-O-l is set to 'pusch-RepTypeA' or 'pusch-RepTypeB' with 'Inter-repetition frequency hopping'. The value interRepetition enables 'Inter-repetition frequency hopping', and the value interSlot enables 'Inter-slot frequency hopping', and the value intraSlot enables 'intra-slot frequency hopping'. If the field is absent, inter-repetition frequency hopping is not configured for DCI format 0_1 for 'pusch-RepTypeA' and frequency hopping is not configured for DCI format 0_1 for 'pusch-RepTypeB'. Or the RRC parameter frequencyHoppingDCI-0-l-rl7 may indicate the frequency hopping scheme for DCI format 0_1 when pusch-RepTypelndicatorDCI-O-l is set to 'pusch-RepTypeA' enabling 'Inter-repetition frequency hopping'.

[0256] In case of resource allocation type 2, the UE transmits PUSCH without frequency hopping.

[0257] In case of resource allocation type 1 , whether or not transform precoding is enabled for PUSCH transmission, the UE may perform PUSCH frequency hopping, if the frequency hopping field in a corresponding detected DCI format or in a random access response UL grant is set to 1, or if for a Type 1 PUSCH transmission with a configured grant the RRC parameter frequencyHoppingOffset is provided, otherwise no PUSCH frequency hopping is performed. When frequency hopping is enabled for PUSCH, the RE mapping is defined in those procedures.

[0258] For a PUSCH scheduled by RAR UL grant, fallbackRAR UL grant, or by DCI format 0_0 with CRC scrambled by TC-RNTI, frequency offsets are obtained as described in those procedures. For a PUSCH scheduled by DCI format 0_0/0_1 or a PUSCH based on a Type2 configured UL grant activated by DCI format 0_0/0_1 and for resource allocation type 1, frequency offsets are configured by RRC parameter frequencyHoppingOffsetLists in pusch-Config. For a PUSCH scheduled by DCI format 0 2 or a PUSCH based on a Type2 configured UL grant activated by DCI format 0 2 and for resource allocation type 1, frequency offsets are configured by RRC parameter frequencyHoppingOffsetListsDCI-O-2 in pusch-Config. When the size of the active B WP is less than 50 PRBs, one of two higher layer configured offsets is indicated in the UL grant. When the size of the active BWP is equal to or greater than 50 PRBs, one of four higher layer configured offsets is indicated in the UL grant.

[0259] For PUSCH based on a Typel configured UL grant the frequency offset is provided by the RRC parameter frequencyHoppingOffset in rrc-ConfiguredUplinkGrant. [0260] For PUSCH repetition Type B (as determined according to procedures defined in those procedures for scheduled PUSCH, or those procedures for configured PUSCH), a UE is configured for frequency hopping by the RRC parameter frequencyHoppingDCI- 0-2 in pusch-Config for PUSCH transmission scheduled by DCI format 0 2, by frequencyHoppingDCI-0-1 provided in pusch-Config for PUSCH transmission scheduled by DCI format 0_1, and by frequencyHoppingPUSCH-RepTypeB provided in rrc- ConfiguredUplinkGrant for Type 1 configured PUSCH transmission. The frequency hopping mode for Type 2 configured PUSCH transmission follows the configuration of the activating DCI format. One of two frequency hopping modes (Inter-repetition frequency hopping and Inter-slot frequency hopping) can be configured.

[0261] In case of resource allocation type 1, whether or not transform precoding is enabled for PUSCH transmission, the UE may perform PUSCH frequency hopping, if the frequency hopping field in a corresponding detected DCI format is set to 1 , or if for a Type 1 PUSCH transmission with a configured grant the RRC parameter frequencyHoppingPUSCH-RepTypeB is provided, otherwise no PUSCH frequency hopping is performed. When frequency hopping is enabled for PUSCH, the RE mapping is defined in those procedures.

[0262] For a PUSCH scheduled by DCI format 0_1 or a PUSCH based on a Type 2 configured UL grant activated by DCI format 0_1 and for resource allocation type 1, frequency offsets are configured by RRC parameter frequencyHoppingOffsetLists in pusch-Config. For a PUSCH scheduled by DCI format 0 2 or a PUSCH based on a Type 2 configured UL grant activated by DCI format 0 2 and for resource allocation type 1 , frequency offsets are configured by RRC parameter frequencyHoppingOffsetListsDCI- 0-2 in pusch-Config. When the size of the active BWP is less than 50 PRBs, one of two higher layer configured offsets is indicated in the UL grant. When the size of the active BWP is equal to or greater than 50 PRBs, one of four higher layer configured offsets is indicated in the UL grant.

[0263] For PUSCH based on a Typel configured UL grant the frequency offset is provided by the RRC parameter frequencyHoppingOffset in rrc-ConfiguredUplinkGrant. [0264] In case of inter-slot frequency hopping, the starting RB during slot n ^A u_s follows that of inter-slot frequency hopping for PUSCH Repetition Type A according to at least one of the conditions defined in those procedures. [0265] If the UE is not capable of a certain coverage enhancement feature(s) (e.g. available slot based PUSCH repetition counting) or if the UE is not provided with a certain coverage enhancement configuration(s) (e.g. available slot based PUSCH repetition counting), the following (i.e. the number of repetitions counted based on contiguous (or continuous, or consecutive) slots) may be applied. Alternatively or additionally, if the UE is capable of a certain coverage enhancement feature(s) and if the UE is provided with a slot-counting type configuration (the RRC configuration or RRC parameter for indicating whether the number of repetitions are counted based on contiguous (or continuous) slots or based on available slots) which indicates the PUSCH repetition to be counted based on contiguous slots, the following may be applied. For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when K > 1, the UE may repeat the TB across the K consecutive slots applying the same symbol allocation in each slot, except if the UE is provided with RRC parameters cg-nrofSlots and cg- nrofPUSCH-InSlot, in which case the UE may repeat the TB in the repK earliest consecutive transmission occasion candidates within the same configuration. A Type 1 or Type 2 PUSCH transmission with a configured grant in a slot may be omitted according to the conditions at least and/or at most in, PUSCH-priority based procedure, slot configuration based procedure, slot format based procedure and cancellation indication based procedure. For example, a slot may be determined as available if the slot is available according to all the conditions defined in those procedures, and/or the slot may be determined as not available if the slot is not available according to at least one of the conditions defined in those procedures.

[0266] It is noted that the aforementioned slot-counting type configuration may be referred to as a different name. The existence of the slot-counting type configuration in RRC configuration message may mean that the number of repetitions is counted based on available slots while the absence of the slot-counting type configuration in RRC configuration message may mean that the number of repetitions is counted based on contiguous slots. Additionally and/or alternatively, the slot-counting type configuration set to the first value (e.g. ‘contiguous’) may mean that the number of repetitions is counted based on contiguous slots while the slot-counting type configuration set to the second value (e.g. ‘available’) may mean that the number of repetitions is counted based on available slots.

[0267] If the UE is capable of a certain coverage enhancement feature(s) and/or if the UE is provided with a certain coverage enhancement configuration(s), the following (i.e. the number of repetitions counted based on available slots) may be applied. Alternatively or additionally, if the UE is capable of a certain coverage enhancement feature(s) and if the UE is provided with a slot-counting type configuration which indicates the PUSCH repetition to be counted based on available slots, the following may be applied. For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when K > 1, the UE may repeat the TB across the K available slots (i.e. the first K slots which are available for the PUSCH transmission) applying the same symbol allocation in each slot. The K available slots may be determined according to the conditions at least and/or at most in, PUSCH-priority based procedure, slot configuration based procedure, slot format based procedure and cancellation indication based procedure. For example, a slot may be determined as available if the slot is available according to all the conditions defined in those procedures, and/or the slot may be determined as not available if the slot is not available according to at least one of the conditions defined in those procedures. [0268] The patern of inter-slot frequency hopping according to the available slots may be determined based on the omission of PUSCH transmissions.

[0269] The patern of RV according to the available slots may be determined based on the omission of PUSCH transmissions.

[0270] The patern of slot-counting according to the available slots may be determined based on the omission of PUSCH transmissions.

[0271] The PUSCH-priority based procedure is described. If a PUSCH is scheduled by a DCI or a PUSCH with configured grant is configured, the PUSCH is transmited unless otherwise stated.

[0272] A PUSCH or a PUCCH transmission, including repetitions if any, can be of priority index 0 or of priority index 1. For a configured grant PUSCH transmission, a UE may determine a priority index from RRC parameter phy-Prioritylndex, if provided. For a PUCCH transmission with HARQ-ACK information corresponding to a SPS PDSCH reception or a SPS PDSCH release, a UE may determine a priority index from RRC parameter harq-CodebookID, if provided. For a PUCCH transmission with SR, a UE may determine the corresponding priority by RRC parameter phy-Prioritylndex in RRC parameter SchedulingRequestResourceConfig, if any. For a PUSCH transmission with semi-persistent CSI report, a UE may determine a priority index from a priority indicator field, if provided, in a DCI format that activates the semi-persistent CSI report. If a priority index is not provided to a UE for a PUSCH or a PUCCH transmission, the priority index may be 0.

[0273] If in an active DL B WP a UE may monitor PDCCH either for detection of DCI format 0_1 and DCI format 1_1 or for detection of DCI format 0 2 and DCI format 1 2, a priority index can be provided by a priority indicator field. If a UE indicates a capability to monitor, in an active DL BWP, PDCCH for detection of DCI format 0_1 and DCI format 1_1 and for detection of DCI format 0 2 and DCI format 1 2, a DCI format 0_1 or a DCI format 0 2 can schedule a PUSCH transmission of any priority and a DCI format 1_1 or a DCI format 1 2 can schedule a PDSCH reception and trigger a PUCCH transmission with corresponding HARQ-ACK information of any priority.

[0274] When a UE determines overlapping for PUCCH and/or PUSCH transmissions of different priority indexes, including repetitions if any, the UE may first resolve the overlapping for PUCCH and/or PUSCH transmissions of smaller priority index. Then: if a transmission of a first PUCCH of larger priority index scheduled by a DCI format in a PDCCH reception would overlap in time with a repetition of a transmission of a second PUSCH or a second PUCCH of smaller priority index, the UE may cancel the repetition of a transmission of the second PUSCH or the second PUCCH before the first symbol that would overlap with the first PUCCH transmission; if a transmission of a first PUSCH of larger priority index scheduled by a DCI format in a PDCCH reception would overlap in time with a repetition of the transmission of a second PUCCH of smaller priority index, the UE may cancel the repetition of the transmission of the second PUCCH before the first symbol that would overlap with the first PUSCH transmission. The overlapping may be applicable before or after resolving overlapping among channels of larger priority index, if any. The UE may expect that the transmission of the first PUCCH or the first PUSCH, respectively, would not start before T_(proc,2)+d_l after a last symbol of the corresponding PDCCH reception. T_(proc,2) is the PUSCH preparation time for a corresponding UE processing capability assuming d_2,l=0, based on p and N_2, and d_l is determined by a reported UE capability. [0275] If the slot-counting type configuration indicates that the number of repetitions to be counted based on contiguous slots, the above-described processing time requirement that the first PUSCH would not start before T_(proc,2)+d_l after a last symbol of the corresponding PDCCH reception may be applied. If the slot-counting type configuration indicates that the number of repetitions to be counted based on available slots, the processing time requirement may be relaxed. For example, the processing time requirement that the first PUSCH would not start before T_(proc,2)+d_l+d_x after a last symbol of the corresponding PDCCH reception may be applied, where d_x is a positive value. The d_x may be expressed in unit of symbols. In other words, If the number of repetitions for PUSCH repetition type A is counted based on contiguous slots, the processing time requirement that the first PUSCH would not start before T_(proc,2)+d_l after a last symbol of the corresponding PDCCH reception may be applied. If the number of repetitions for PUSCH repetition type A is counted based on available slots, the processing time requirement may be relaxed. The relaxation of the processing time requirement may mean allowing longer gap duration between PUSCH start and the end of the corresponding PDCCH, where the processing time requirement may be the maximum processing time which is required for cancellation of a scheduled/configured/granted PUSCH transmission.

[0276] If a UE is scheduled by a DCI format in a first PDCCH reception to transmit a first PUCCH or a first PUSCH of larger priority index that overlaps with a second PUCCH or a second PUSCH transmission of smaller priority index that, if any, is scheduled by a DCI format in a second PDCCH, T_(proc,2) may be based on a value of p corresponding to the smallest SCS configuration of the first PDCCH, the second PDCCHs, the first PUCCH or the first PUSCH, and the second PUCCHs or the second PUSCHs. If the overlapping group includes the first PUCCH, N_2 is 5 for μ=0, 5.5 for μ=1 and 11 for μ=2 if RRC parameter processingType2Enabled of RRC parameter PDSCH-ServingCellConfig is set to enable for the serving cell where the UE receives the first PDCCH and for all serving cells where the UE receives the PDSCHs corresponding to the second PUCCHs, and if processingType2Enabled of RRC parameter PUSCH- ServingCellConfig is set to enable for the serving cells with the second PUSCHs, N_2 is 10 for μ=0, 12 for μ=l, 23 for μ=2, and 36 for μ=3 otherwise. If the overlapping group includes the first PUSCH, N_2 is 5 for μ=0, 5.5 for μ=1 and 11 for μ=2 if processingType2Enabled of PUSCH-ServingCellConfig is set to enable for the serving cells with the first PUSCH and the second PUSCHs and if processingType2Enabled of PDSCH-ServingCellConfig is set to enable for all serving cells where the UE receives the PDSCHs corresponding to the second PUCCHs, N_2 is 10 for μ=0, 12 for μ=l, 23 for μ=2, and 36 for μ=3 otherwise.

[0277] If a UE would transmit the following channels, including repetitions if any, that would overlap in time: a first PUCCH of larger priority index with SR and a second PUCCH or PUSCH of smaller priority index; or a configured grant PUSCH of larger priority index and a PUCCH of smaller priority index; or a first PUCCH of larger priority index with HARQ-ACK information only in response to a PDSCH reception without a corresponding PDCCH and a second PUCCH of smaller priority index with SR and/or CSI, or a configured grant PUSCH with smaller priority index, or a PUSCH of smaller priority index with SP-CSI report(s) without a corresponding PDCCH; or a PUSCH of larger priority index with SP-CSI reports(s) without a corresponding PDCCH and a PUCCH of smaller priority index with SR, or CSI, or HARQ-ACK information only in response to a PDSCH reception without a corresponding PDCCH; or a configured grant PUSCH of larger priority index and a configured PUSCH of lower priority index on a same serving cell, the UE may be expected to cancel a repetition of the PUCCH/PUSCH transmissions of smaller priority index before the first symbol overlapping with the PUCCH/PUSCH transmission of larger priority index if the repetition of the PUCCH/PUSCH transmissions of smaller priority index overlaps in time with the PUCCH/PUSCH transmissions of larger priority index.

[0278] A UE may not expect to be scheduled to transmit a PUCCH or a PUSCH with smaller priority index that would overlap in time with a PUCCH of larger priority index with HARQ-ACK information only in response to a PDSCH reception without a corresponding PDCCH. A UE may not expect to be scheduled to transmit a PUCCH of smaller priority index that would overlap in time with a PUSCH of larger priority index with SP-CSI report(s) without a corresponding PDCCH.

[0279] If a UE multiplexes aperiodic CSI in a PUSCH and the UE would multiplex UCI that includes HARQ-ACK information in a PUCCH that overlaps with the PUSCH and the timing conditions for overlapping PUCCHs and PUSCHs are fulfilled, the UE may multiplex only the HARQ-ACK information in the PUSCH and does not transmit the PUCCH.

[0280] If a UE transmits multiple PUSCHs in a slot on respective serving cells that include first PUSCHs that are scheduled by DCI formats and second PUSCHs configured by respective RRC parameter ConfiguredGrantConfig or semiPersistentOnPUSCH, and the UE would multiplex UCI in one of the multiple PUSCHs, and the multiple PUSCHs fulfil the conditions for UCI multiplexing, the UE may multiplex the UCI in a PUSCH from the first PUSCHs. [0281] If a UE transmits multiple PUSCHs in a slot on respective serving cells and the UE would multiplex UCI in one of the multiple PUSCHs and the UE does not multiplex aperiodic CSI in any of the multiple PUSCHs, the UE may multiplex the UCI in a PUSCH of the serving cell with the smallest RRC parameter ServCelllndex subject to the conditions for UCI multiplexing being fulfilled. If the UE transmits more than one PUSCHs in the slot on the serving cell with the smallest ServCelllndex that fulfil the conditions for UCI multiplexing, the UE may multiplex the UCI in the earliest PUSCH that the UE transmits in the slot.

[0282] If a UE transmits a PUSCH over multiple slots and the UE would transmit a PUCCH with HARQ-ACK and/or CSI information over a single slot that overlaps with the PUSCH transmission in one or more slots of the multiple slots, and the PUSCH transmission in the one or more slots fulfills the conditions for multiplexing the HARQ- ACK and/or CSI information, the UE may multiplex the HARQ-ACK and/or CSI information in the PUSCH transmission in the one or more slots. The UE may not multiplex HARQ-ACK and/or CSI information in the PUSCH transmission in a slot from the multiple slots if the UE would not transmit a single-slot PUCCH with HARQ-ACK and/or CSI information in the slot in case the PUSCH transmission was absent.

[0283] If the PUSCH transmission over the multiple slots is scheduled by a DCI format that includes a DAI field, the value of the DAI field may be applicable for multiplexing HARQ-ACK information in the PUSCH transmission in any slot from the multiple slots where the UE multiplexes HARQ-ACK information.

[0284] When a UE would multiplex HARQ-ACK information in a PUSCH transmission that is configured by an RRC parameter ConfiguredGrantConfig, and includes CG-UCI, the UE may multiplex the HARQ-ACK information in the PUSCH transmission if the UE is provided RRC parameter cg-UCI-Multiplexing; otherwise, the UE does not transmit the PUSCH and multiplexes the HARQ-ACK information in a PUCCH transmission or in another PUSCH transmission.

[0285] If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be transmitted or to multiplex UCI(s), the slot may be considered as available for the PUSCH transmission. If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be cancelled, the slot may be considered as not available for the PUSCH transmission.

[0286] The slot configuration based procedure is described. If a PUSCH is scheduled by a DCI or a PUSCH with configured grant is configured, the PUSCH is transmitted unless otherwise stated.

[0287] If a UE is provided RRC parameter tdd-UL-DL-ConfigurationCommon, the UE may set the slot format (the format which indicates which type of symbol between downlink, uplink and flexible symbols each symbol in a slot is) per slot over a number of slots as indicated by tdd-UL-DL-ConfigurationCommon. If the UE is additionally provided RRC parameter tdd-UL-DL-ConfigurationDedicated, the parameter tdd-UL- DL-ConfigurationDedicated may override only flexible symbols per slot over the number of slots as provided by tdd-UL-DL-ConfigurationCommon.

[0288] For operation on a single carrier in unpaired spectrum, if a UE is configured by higher layers to receive a PDCCH, or a PDSCH, or a CSI-RS, or a DL PRS in a set of symbols of a slot, the UE receives the PDCCH, the PDSCH, the CSI-RS, or the DL PRS if the UE does not detect a DCI format that indicates to the UE to transmit a PUSCH, a PUCCH, a PRACH, or a SRS in at least one symbol of the set of symbols of the slot; otherwise, the UE may not receive the PDCCH, or the PDSCH, or the CSI-RS, or the DL PRS in the set of symbols of the slot. [0289] For operation on a single carrier in unpaired spectrum, if a UE is configured by higher layers to transmit SRS, or PUCCH, or PUSCH, or PRACH in a set of symbols of a slot and the UE detects a DCI format indicating to the UE to receive CSI-RS or PDSCH in a subset of symbols from the set of symbols, then: the following A), B) and C) may be applied. A) If the UE does not indicate the capability of partialCancellation, the UE does not expect to cancel the transmission of the PUCCH or PUSCH or PRACH in the set of symbols if the first symbol in the set occurs within T_(proc, 2) relative to a last symbol of a CORESET where the UE detects the DCI format; otherwise, the UE cancels the PUCCH, or the PUSCH, or an actual repetition of the PUSCH, or the PRACH transmission in the set of symbols. B) If the UE indicates the capability of partialCancellation, the UE does not expect to cancel the transmission of the PUCCH or PUSCH or PRACH in symbols from the set of symbols that occur within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format. The UE cancels the PUCCH, or the PUSCH, or an actual repetition of the PUSCH, or the PRACH transmission in remaining symbols from the set of symbols. C) The UE does not expect to cancel the transmission of SRS in symbols from the subset of symbols that occur within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format. The UE cancels the SRS transmission in remaining symbols from the subset of symbols. T_(proc,2) is the PUSCH preparation time for the corresponding UE processing capability assuming d_2,l=l and p corresponds to the smallest SCS configuration between the SCS configuration of the PDCCH carrying the DCI format and the SCS configuration of the SRS, PUCCH, PUSCH or μ_r, where μ_r corresponds to the SCS configuration of the PRACH if it is 15kHz or higher; otherwise μ_r=0. [0290] If the slot-counting type configuration indicates that the number of repetitions to be counted based on contiguous slots, the above-described processing time requirement that “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format, otherwise UE cancels the PUSCH transmission” may be applied. If the slot-counting type configuration indicates that the number of repetitions to be counted based on available slots, the processing time requirement may be relaxed. For example, “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T_(proc,2)+d_x relative to a last symbol of a CORESET where the UE detects the DCI format, otherwise UE cancels the PUSCH transmission” may be applied, where d_x is a positive value. In other words, If the number of repetitions for PUSCH repetition type A is counted based on contiguous slots, the processing time requirement of T_(proc,2) may be applied. If the number of repetitions for PUSCH repetition type A is counted based on available slots, the longer processing time requirement may be applied.

[0291] For a set of symbols of a slot that are indicated to a UE as downlink by tdd- UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated, the UE may not transmit PUSCH, PUCCH, PRACH, or SRS when the PUSCH, PUCCH, PRACH, or SRS overlaps, even partially, with the set of symbols of the slot.

[0292] For a set of symbols of a slot that are indicated to a UE as flexible by tdd-UL- DL-ConfigurationCommon, and tdd-UL-DL-ConfigurationDedicated if provided, the UE may not expect to receive both dedicated RRC parameters configuring transmission from the UE in the set of symbols of the slot and dedicated RRC parameters configuring reception by the UE in the set of symbols of the slot. {0293] For operation on a single carrier in unpaired spectrum, for a set of symbols of a slot indicated to a UE by RRC parameter ssb-PositionsInBurst in SIB1 or ssb- PositionsInBurst in ServingCellConfigCommon, for reception of SS/PBCH blocks, the UE may not transmit PUSCH, PUCCH, PRACH in the slot if a transmission would overlap with any symbol from the set of symbols and the UE does not transmit SRS in the set of symbols of the slot. The UE may not expect the set of symbols of the slot to be indicated as uplink by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL- ConfigurationDedicated, when provided to the UE.

[0294] If a UE is scheduled by a DCI format to transmit PUSCH over multiple slots, and if tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated, indicates that, for a slot from the multiple slots, at least one symbol from a set of symbols where the UE is scheduled PUSCH transmission in the slot is a downlink symbol, the UE may not transmit the PUSCH in the slot.

[0295] If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be transmitted, the slot may be considered as available for the PUSCH transmission. If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be cancelled or not to be transmitted, the slot may be considered as not available for the PUSCH transmission.

[0296] An example of the definition of T_(proc,2) is described. If the first uplink symbol in the PUSCH allocation for a transport block, including the DM-RS, as defined by the slot offset K2 and the start S and length L of the PUSCH allocation indicated by 'Time domain resource assignment' of the scheduling DCI and including the effect of the timing advance, is no earlier than at symbol L2, where L2 is defined as the next uplink symbol with its CP starting T_(proc,2) after the end of the reception of the last symbol of the PDCCH carrying the DCI scheduling the PUSCH, then the UE may transmit the transport block. N2 is based on p for UE processing capability 1 and 2 respectively, where p corresponds to the one of (pDL, pUL) resulting with the largest T_(proc,2), where the pDL corresponds to the subcarrier spacing of the downlink with which the PDCCH carrying the DCI scheduling the PUSCH was transmitted and pUL corresponds to the subcarrier spacing of the uplink channel with which the PUSCH is to be transmitted, and the constant K is 64. For operation with shared spectrum channel access, T ext may be non-zero value, otherwise T ext =0. If the first symbol of the PUSCH allocation consists of DM-RS only, then d2,l = 0, otherwise d2,l = 1. The time units T_C = l/(Δf_"max" N_f) where Δf_"max" =480 10 ^A 3 Hz and N_f = 4096. If the UE is configured with multiple active component carriers, the first uplink symbol in the PUSCH allocation further includes the effect of timing difference between component carriers. If the scheduling DCI triggered a switch of BWP, d2,2 equals to the switching time, otherwise d2,2=0. If a PUSCH of a larger priority index would overlap with PUCCH of a smaller priority index, d2 for the PUSCH of a larger priority is set as reported by the UE; otherwise d2 = 0. For a UE that supports capability 2 on a given cell, the processing time according to UE processing capability 2 is applied if the high layer parameter processingType2Enabled in PUSCH-ServingCellConfig is configured for the cell and set to 'enable'. If the PUSCH indicated by the DCI is overlapping with one or more PUCCH channels, then the transport block is multiplexed, otherwise the transport block is transmitted on the PUSCH indicated by the DCI. If uplink switching gap is triggered, T switch equals to the switching gap duration and for the UE configured with RRC parameter uplinkTxSwitchingOption set to 'dualUL' for uplink carrier aggregation pUL=min(|iUL, carrier!, pUL,carrier2), otherwise T_switch = 0. For PUSCH preparation time for PUSCH timing capability 1, PUSCH preparation time N2 is 10, 12, 23 and 36 symbols for μ= 0, 1, 2 and 3, respectively. For PUSCH preparation time for PUSCH timing capability 2, PUSCH preparation time N2 is 5, 5.5 and 11 symbols (for frequency range (FR) 1) for μ= 0, 1 and 2, respectively.

[0297] The slot format based procedure is described. If a PUSCH is scheduled by a DCI or a PUSCH with configured grant is configured, the PUSCH is transmitted unless otherwise stated.

[0298] This procedure may apply for a serving cell that is included in a set of serving cells configured to a UE by RRC parameter slotFormatCombToAddModList and slotFormatCombToReleaseList, availableRB-SetsToAddModList and availableRB- SetsToRelease, switchTriggerToAddModList and switchTriggerToReleaseList, or co- DurationsPerCellToAddModList and co-DurationsPerCellToReleaseList.

[0299] A SFI-index field value in a DCI format 2_0 may indicate to a UE a slot format for each slot in a number of slots for each DL BWP or each UL BWP starting from a slot where the UE detects the DCI format 2_0. The number of slots may be equal to or larger than a PDCCH monitoring periodicity for DCI format 2_0. The SFI-index field may include maxSFIindex bits where maxSFIindex is the maximum value of the values provided by corresponding RRC parameter slotFormatCombinationld. A slot format may be identified by a corresponding format index as provided in the table in which each entry specifies a respective combination of ‘D’, ‘U’ and/or ‘F’, where 'D' denotes a downlink symbol, 'U' denotes an uplink symbol, and 'F' denotes a flexible symbol. The index 255 may indicate that UE determines the slot format for the slot based on tdd-UL-DL- ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated and, if any, on detected DCI formats. [0300] For a set of symbols of a slot, a UE may not expect to detect a DCI format 2_0 with an SFI-index field value indicating the set of symbols of the slot as uplink and to detect a DCI format indicating to the UE to receive PDSCH or CSI-RS in the set of symbols of the slot.

[0301] For a set of symbols of a slot, a UE may not expect to detect a DCI format 2_0 with an SFI-index field value indicating the set of symbols in the slot as downlink and to detect a DCI format, a RAR UL grant, fallbackRAR UL grant, or successRAR indicating to the UE to transmit PUSCH, PUCCH, PRACH, or SRS in the set of symbols of the slot. [0302] For a set of symbols of a slot that are indicated as downlink/uplink by tdd-UL- DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated, the UE may not expect to detect a DCI format 2_0 with an SFI-index field value indicating the set of symbols of the slot as uplink/downlink, respectively, or as flexible.

[0303] For a set of symbols of a slot indicated to a UE as flexible by tdd-UL-DL- ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated if provided, or when tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not provided to the UE, and if the UE detects a DCI format 2_0 providing a format for the slot using a slot format value other than 255, at least the following A) to E) may be applied. A) If an SFI-index field value in DCI format 2_0 indicates the set of symbols of the slot as flexible and the UE detects a DCI format, a RAR UL grant, fallbackRAR UL grant, or successRAR indicating to the UE to transmit PUSCH, PUCCH, PRACH, or SRS in the set of symbols of the slot the UE transmits the PUSCH, PUCCH, PRACH, or SRS in the set of symbols of the slot. B) If an SFI-index field value in DCI format 2_0 indicates the set of symbols of the slot as flexible, and the UE does not detect a DCI format indicating to the UE to receive PDSCH or CSI-RS, or the UE does not detect a DCI format, a RAR UL, fallbackRAR UL grant, or successRAR grant indicating to the UE to transmit PUSCH, PUCCH, PRACH, or SRS in the set of symbols of the slot, the UE does not transmit or receive in the set of symbols of the slot. C) If the UE is configured by higher layers to transmit PUCCH, or PUSCH, or PRACH in the set of symbols of the slot, the UE transmits the PUCCH, or the PUSCH, or the PRACH in the slot only if an SFI-index field value in DCI format 2_0 indicates the set of symbols of the slot as uplink. D) A UE does not expect to detect an SFI-index field value in DCI format 2_0 indicating the set of symbols of the slot as downlink and also detect a DCI format, a RAR UL grant, fallbackRAR UL grant, or successRAR indicating to the UE to transmit SRS, PUSCH, PUCCH, or PRACH, in one or more symbols from the set of symbols of the slot. E) A UE does not expect to detect an SFI-index field value in DCI format 2_0 indicating the set of symbols of the slot as downlink or flexible if the set of symbols of the slot includes symbols corresponding to any repetition of a PUSCH transmission activated (i.e. scheduled) by an UL Type 2 grant PDCCH.

[0304J If a UE is configured by higher layers to transmit SRS, or PUCCH, or PUSCH, or PRACH in a set of symbols of a slot and the UE detects a DCI format 2_0 with a slot format value other than 255 that indicates a slot format with a subset of symbols from the set of symbols as downlink or flexible, or the UE detects a DCI format indicating to the UE to receive CSI-RS or PDSCH in a subset of symbols from the set of symbols, then the following A), B) and C) may be applied. A) If the UE does not indicate the capability of partialCancellation, the UE does not expect to cancel the transmission of the PUCCH or PUSCH or PRACH in the set of symbols if the first symbol in the set occurs within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format; otherwise, the UE cancels the PUCCH, or the PUSCH, or an actual repetition of the PUSCH, or the PRACH transmission in the set of symbols. B) If the UE indicates the capability of partialCancellation, the UE does not expect to cancel the transmission of the PUCCH or PUSCH or PRACH in symbols from the set of symbols that occur within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format. The UE cancels the PUCCH, or the PUSCH, or an actual repetition of the PUSCH, or the PRACH transmission in remaining symbols from the set of symbols. C) The UE does not expect to cancel the transmission of SRS in symbols from the subset of symbols that occur within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format. The UE cancels the SRS transmission in remaining symbols from the subset of symbols. T_(proc,2) is the PUSCH preparation time for the corresponding UE processing capability assuming d_2,l=l and p corresponds to the smallest SCS configuration between the SCS configuration of the PDCCH carrying the DCI format and the SCS configuration of the SRS, PUCCH, PUSCH or μ_r, where μ_r corresponds to the SCS configuration of the PRACH if it is 15kHz or higher; otherwise μ_r=0.

[0305] If the slot-counting type configuration indicates that the number of repetitions to be counted based on contiguous slots, the above-described processing time requirement that “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T_(proc,2) relative to a last symbol of a CORESET where the UE detects the DCI format, otherwise UE cancels the PUSCH transmission” may be applied. If the slot-counting type configuration indicates that the number of repetitions to be counted based on available slots, the processing time requirement may be relaxed. For example, “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T_(proc,2)+d_x relative to a last symbol of a CORESET where the UE detects the DCI format, otherwise UE cancels the PUSCH transmission” may be applied, where d_x is a positive value. In other words, If the number of repetitions for PUSCH repetition type A is counted based on contiguous slots, the processing time requirement of T_(proc,2) may be applied. If the number of repetitions for PUSCH repetition type A is counted based on available slots, the longer processing time requirement may be applied.

[0306] AUE may assume that flexible symbols in a CORESET configured to the UE for PDCCH monitoring are downlink symbols if the UE does not detect an SFI-index field value in DCI format 2_0 indicating the set of symbols of the slot as flexible or uplink and the UE does not detect a DCI format indicating to the UE to transmit SRS, PUSCH, PUCCH, or PRACH in the set of symbols.

[0307] For a set of symbols of a slot that are indicated as flexible by tdd-UL-DL- ConfigurationCommon, and tdd-UL-DL-ConfigurationDedicated if provided, or when tdd-UL-DL-ConfigurationCommon, and tdd-UL-DL-ConfigurationDedicated are not provided to the UE, and if the UE does not detect a DCI format 2_0 providing a slot format for the slot, at least the following A) may be applied. A) The UE transmits PUSCH, PUCCH, PRACH, or SRS in the set of symbols of the slot if the UE receives a corresponding indication by a DCI format, a RAR UL grant, fallbackRAR UL grant, or successRAR.

[0308] If the UE is configured by higher layers to transmit SRS, or PUCCH, or PUSCH, or PRACH in the set of symbols of the slot and the UE is not provided RRC parameter enableConfiguredUL, the following A) and B) may be applied. A) The UE does not transmit the PUCCH, or the PUSCH, or the PRACH in the slot and does not transmit the SRS in symbols from the set of symbols in the slot, if any, starting from a symbol that is after PUSCH preparation time T_(proc,2) for the corresponding PUSCH timing capability assuming d_2,l=l after a last symbol of a CORESET where the UE is configured to monitor PDCCH for DCI format 2_0 and p corresponds to the smallest SCS configuration between the SCS configuration of the PDCCH carrying the DCI format 2_0 and the SCS configuration of the SRS, PUCCH, PUSCH or μ_r, where μ_r corresponds to the SCS configuration of the PRACH if it is 15kHz or higher; otherwise μ_r=0. B) The UE does not expect to cancel the transmission of the SRS, or the PUCCH, or the PUSCH, or the PRACH in symbols from the set of symbols in the slot, if any, starting before a symbol that is after the PUSCH preparation time T_(proc,2) for the corresponding PUSCH timing capability assuming d_2,l=l after a last symbol of a CORESET where the UE is configured to monitor PDCCH for DCI format 2_0 and p corresponds to the smallest SCS configuration between the SCS configuration of the PDCCH carrying the DCI format 2_0 and the SCS configuration of the SRS, PUCCH, PUSCH or μ_r, where μ_r corresponds to the SCS configuration of the PRACH if it is 15kHz or higher; otherwise μ_r=0.

[0309] If the slot-counting type configuration indicates that the number of repetitions to be counted based on contiguous slots, the above-described processing time requirement that “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T_(proc,2) relative to a last symbol of a CORESET where the UE monitor the DCI format 2_0, otherwise UE cancels the PUSCH transmission” may be applied. If the slot-counting type configuration indicates that the number of repetitions to be counted based on available slots, the processing time requirement may be relaxed. For example, “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T_(proc,2)+d_x relative to a last symbol of a CORESET where the UE monitors the DCI format 2_0, otherwise UE cancels the PUSCH transmission” may be applied, where d_x is a positive value. In other words, If the number of repetitions for PUSCH repetition type A is counted based on contiguous slots, the processing time requirement of T_(proc,2) may be applied. If the number of repetitions for PUSCH repetition type A is counted based on available slots, the longer processing time requirement may be applied.

[0310] If the UE is configured by higher layers to transmit SRS, or PUCCH, or PUSCH, or PRACH in the set of symbols of the slot and the UE is provided enableConfiguredUL, the UE can transmit the SRS, or PUCCH, or PUSCH, or PRACH, respectively.

[0311] If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be transmitted, the slot may be considered as available for the PUSCH transmission. If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be cancelled or not to be transmitted, of if at least one symbol for the PUSCH in the slot is determined as a downlink symbol, the slot may be considered as not available for the PUSCH transmission.

[0312] The cancellation indication based procedure is described. If a PUSCH is scheduled by a DCI or a PUSCH with configured grant is configured, the PUSCH is transmitted unless otherwise stated.

[0313] If a UE is provided RRC parameter UplinkCancellation, the UE may be provided, in one or more serving cells, a search space set for monitoring the first PDCCH candidate with a CCE aggregation level of L_CI CCEs of the search space set for detection of a DCI format 2 4 with a CI-RNTI provided by ci-RNTI.

[0314] For a serving cell having an associated field in a DCI format 2 4, the field may be denoted by N_"CI" a number of bits provided by RRC parameter ci-PayloadSize, a number of PRBs provided by RRC parameter frequencyRegionforCI in RRC parameter timeFrequencyRegion, T_"CI" a number of symbols, excluding symbols for reception of SS/PBCH blocks and DL symbols indicated by tdd-UL-DL- ConfigurationCommon, from a number of symbols that is provided by RRC parameter timeDurationforCI in RRC parameter timeFrequencyRegion, if the PDCCH monitoring periodicity for the search space set with the DCI format 2 4 is one slot and there are more than one PDCCH monitoring occasions in a slot, or is equal to the PDCCH monitoring periodicity, otherwise, and G_"CI" a number of partitions for the T_"CI" symbols provided by RRC parameter timeGranularityforCI in RRC parameter timeFrequencyRegion.

[0315] An indication by a DCI format 2 4 for a serving cell may be applicable to a PUSCH transmission or an SRS transmission on the serving cell. If the PUSCH transmission or the SRS transmission is scheduled by a DCI format, the indication by the DCI format 2 4 may be applicable to the PUSCH transmission or SRS transmission only if the last symbol of the PDCCH reception providing the DCI format is earlier than the first symbol of the PDCCH reception providing the DCI format 2 4. For the serving cell, the UE may determine the first symbol of the T CI symbols to be the first symbol that is after T’_(proc,2) from the end of a PDCCH reception where the UE detects the DCI format 2 4, where T’_(proc,2) is obtained from T_(proc,2) for PUSCH processing capability 2assuming d_2,l=d_offset 2 ^A (-μ_UL y2 ^A (- ) where d offset is provided by RRC parameter delta Offset, p being the smallest SCS configuration between the SCS configuration of the PDCCH and the smallest SCS configuration μ_UL provided in RRC parameter scs-SpecificCarrierList of FrequencylnfoUL or FrequencylnfoUL-SIB. The UE may not expect to cancel the PUSCH transmission or the SRS transmission before a corresponding symbol that is T_(proc,2) assuming that d_2,1=0 after a last symbol of a CORESET where the UE detects the DCI format 2 4.

[0316] If the slot-counting type configuration indicates that the number of repetitions to be counted based on contiguous slots, the above-described processing time requirement that “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T’_(proc,2) relative to a last symbol of a PDCCH where the UE detects the DCI format 2 4, otherwise UE cancels the PUSCH transmission” may be applied. If the slot-counting type configuration indicates that the number of repetitions to be counted based on available slots, the processing time requirement may be relaxed. For example, “UE does not expect to cancel the transmission of the PUSCH in the set of symbols if the first symbol in the set occurs within T’_(proc,2)+d_x relative to a last symbol of a PDCCH where the UE detects the DCI format 2 4, otherwise UE cancels the PUSCH transmission” may be applied, where d_x is a positive value. In other words, If the number of repetitions for PUSCH repetition type A is counted based on contiguous slots, the processing time requirement of T’_(proc,2) may be applied. If the number of repetitions for PUSCH repetition type A is counted based on available slots, the longer processing time requirement may be applied.

[0317] A UE that detects a DCI format 2_4 for a serving cell may cancel a PUSCH transmission (including PUSCH transmission with repetition Type A), or an actual repetition of a PUSCH transmission if the PUSCH transmission is with repetition Type B, or an SRS transmission on the serving cell if, respectively, the transmission is PUSCH with priority 0 if the UE is provided RRC parameter uplinkCancellationPriority, a group of symbols, from the T_"CI" symbols, has at least one bit value of T in the corresponding set of N_BI bits in the DCI format 2 4 and includes a symbol of the (repetition of the) PUSCH transmission or of the SRS transmission, and a group of PRBs, from the B_"CI" PRBs, has a corresponding bit value of '1' in the set of bits corresponding to the group of symbols in the DCI format 2 4 and includes a PRB of the (repetition of the) PUSCH transmission or of the SRS transmission. The cancellation of the (repetition of the) PUSCH transmission may include all symbols from the earliest symbol of the (repetition of the) PUSCH transmission that is in a group of symbols having corresponding bit values of T' in the DCI format 2_4. The cancellation of the SRS transmission may include only symbols that are in one or more groups of symbols having corresponding bit values of T in the DCI format 2 4

[0318] If, based on an indication by a DCI format 2 4, a UE cancels a PUSCH transmission or an SRS transmission, the UE may not expect to be scheduled by a second DCI format to transmit a PUSCH or an SRS over symbols that include symbols of the cancelled PUSCH transmission or SRS transmission, where the last symbol of the PDCCH reception providing the second DCI format is later than the first symbol of the PDCCH reception providing the DCI format 2 4.

[0319] If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be transmitted, the slot may be considered as available for the PUSCH transmission. If a PUSCH (or a repetition of a PUSCH) in a slot is determined to be cancelled or not to be transmitted, the slot may be considered as not available for the PUSCH transmission.

[0320] When the number of repetitions is counted based on available slots, there may be several sub-options in terms of consideration of the conditions in PUSCH-priority based procedure, slot configuration based procedure, slot format based procedure and cancellation indication based procedure. The conditions according to the slot configuration procedure may be always applicable. Whether the conditions in the other procedures are applicable may be depending on a certain RRC configuration.

[0321] The first sub-option is to have a single slot-counting type configuration which is applicable to all the conditions. More specifically, if the slot-counting type configuration indicates that the number of repetitions to be counted based on available slots, and if an available-slot type configuration (the RRC configuration or RRC parameter which indicates whether the available slots are determined based on only semistatic configuration or based on both semi-static configuration and dynamic signaling, this configuration may or may not be the same as the slot-counting type configuration) indicates that dynamic signaling is used for the determination of the available slots, the available slots may be determined according to all the conditions of which corresponding RRC configurations are provided. For example, the conditions in PUSCH-priority based procedure may be applicable if phy-Prioritylndex or prioritylndicatorDCI is provided, while the conditions in PUSCH-priority based procedure may be not applicable if phy- Prioritylndex or prioritylndicatorDCI (the procedure which determines whether PUSCH is transmitted or not based on the priority index of the PUSCH)) is not provided. The conditions in slot format based procedure may be applicable if SlotFormatCombinationsPerCell (i.e. RRC parameter/configuration which causes the slot format based procedure (the procedure which determines whether PUSCH is transmitted or not based on the slot format)) is provided, while the conditions in slot format based procedure may be not applicable if SlotFormatCombinationsPerCell is not provided. The conditions in cancellation indication based procedure may be applicable if UplinkCancellation (i.e. RRC parameter/configuration which causes the cancellation indicator based procedure (the procedure which determines whether PUSCH is transmitted or not based on the cancellation indicator)) is provided, while the conditions in cancellation indication based procedure may be not applicable if UplinkCancellation is not provided.

[0322] With the first sub-option, if the UE is capable of a certain coverage enhancement feature(s) and/or if the UE is provided with a certain coverage enhancement configuration(s), alternatively or additionally if the UE is provided with a slot-counting type configuration which indicates the PUSCH repetition to be counted based on available slots and/or if the UE is provided with an available-slot type configuration which indicates dynamic signaling to be used for the determination of the available slots, the following may be applied. For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when K > 1, the UE may repeat the TB across the K available slots (i.e. the first K slots which are available for the PUSCH transmission) applying the same symbol allocation in each slot. The K available slots may be determined according to the conditions in the slot configuration based procedure and additionally in the PUSCH- priority based procedure, the slot format based procedure and the cancellation indication based procedure.

[0323] With the first sub-option, if the UE is capable of a certain coverage enhancement feature(s) and/or if the UE is provided with a certain coverage enhancement configuration(s), alternatively or additionally if the UE is provided with a slot-counting type configuration which indicates the PUSCH repetition to be counted based on available slots and/or if the UE is provided with an available-slot type configuration which indicates only semi-static configuration to be used for the determination of the available slots, the following may be applied. For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when K > 1, the UE may repeat the TB across the K available slots (i.e. the first K slots which are available for the PUSCH transmission) applying the same symbol allocation in each slot. The K available slots may be determined according to the conditions in the slot configuration based procedure but without referring to the conditions in the PUSCH-priority based procedure, the slot format based procedure and the cancellation indication based procedure.

[0324] The second sub-option is to have several slot-counting type configuration, each is applicable to the conditions in a respective procedure. More specifically, if the available-slot type configuration for PUSCH-priority based procedure indicates that PUSCH-priority based transmissions/cancellations are used for the determination of the available slots, the available slots may be determined according to the PUSCH-priority based procedure. Similarly, if the available-slot type configuration for slot format based procedure indicates that slot format based transmissions/cancellations are used for the determination of the available slots, the available slots may be determined according to the slot format based procedure. If the available-slot type configuration for cancellation indication based procedure indicates that cancellation indication based transmissions/cancellations are used for the determination of the available slots, the available slots may be determined according to the cancellation indication based procedure. For example, the conditions in PUSCH-priority based procedure may be applicable if phy-Prioritylndex or prioritylndicatorDCI is provided and also if the available-slot type configuration for PUSCH-priority based procedure indicating use of PUSCH-priority based procedure is provided, while the conditions in PUSCH-priority based procedure may be not applicable otherwise. The conditions in slot format based procedure may be applicable if SlotFormatCombinationsPerCell is provided and also if the available-slot type configuration for slot format based procedure indicating use of slot format based procedure is provided, while the conditions in slot format based procedure may be not applicable otherwise. The conditions in cancellation indication based procedure may be applicable if UplinkCancellation is provided and also if the available- slot type configuration for cancellation indication based procedure indicating use of cancellation indication based procedure is provided, while the conditions in cancellation indication based procedure may be not applicable otherwise. Any combination of the above may also apply. For example, if the available-slot type configuration for PUSCH- priority based procedure is provided, and if the available-slot type configuration for slot format based procedure is provided, but if the available-slot type configuration for cancellation indication based procedure is not provided, the available slot may be determined based on the conditions in slot configuration based procedures and also the conditions in PUSCH-priority based procedure and slot format based procedure, but the conditions according to cancellation indication based procedure are not referred to for the determination of available slots.

[0325] With the second sub-option, if the UE is capable of a certain coverage enhancement feature(s) and/or if the UE is provided with a certain coverage enhancement configuration(s), alternatively or additionally if the UE is provided with a slot-counting type configuration which indicates the PUSCH repetition to be counted based on available slots and if the UE is provided with at least one of available-slot type configurations for PUSCH-priority based procedure, slot format based procedure and cancellation indication based procedure, the following may be applied. For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when K > 1, the UE may repeat the TB across the K available slots (i.e. the first K slots which are available for the PUSCH transmission) applying the same symbol allocation in each slot. The K available slots may be determined according to the conditions in the slot configuration based procedure and additionally in the PUSCH-priority based procedure, the slot format based procedure and the cancellation indication based procedure if, respectively, the available-slot type configuration for PUSCH-priority based procedure, the available-slot type configuration for slot format based procedure, or the available-slot type configuration for cancellation indication based procedure is provided.

[0326] If only semi-static configuration is used for the determination of the available slots and/or any dynamic signaling is not used for the determination of the available slots, the UE determines the K slots for a PUSCH transmission starting from a slot indicated to the UE for the PUSCH transmission and having A) an UL symbol, as described in the slot configuration procedure, or flexible symbol that is not SS/PBCH block symbol, and B) consecutive UL symbols, as described in the slot configuration procedure, or flexible symbols that are not SS/PBCH block symbols, starting from the first symbol, equal to or larger than the number of symbols where the first symbol within a slot and the number of symbols within the slot may. be provided by time domain resource allocation information for the PUSCH.

[0327] It is noted that the aforementioned available-slot type configuration may be referred to as a different name. The existence of the available-slot type configuration in RRC configuration message may mean that the conditions in both the slot configuration procedure and the other procedure(s) are used for the determination of the available slots while the absence of the available-slot type configuration in RRC configuration message may mean that the conditions in the slot configuration procedure but not in the other procedure(s) are used for the determination of the available slots. Additionally and/or alternatively, the available-slot type configuration set to the first value (e.g. ‘semi-static’) may mean that the conditions in the slot configuration procedure but not in the other procedure(s) are used for the determination of the available slots while the available-slot type configuration set to the second value (e.g. ‘dynamic’) may mean that the conditions in both the slot configuration procedure and the other procedure(s) are used for the determination of the available slots.

[0328] Figure 9 is an example configuration of a frame structure according to an aspect of the present embodiment. In Figure 9, a horizontal axis indicates time domain. In the time domain, slots are numbered from slot#n (slot with index n) in ascending order. Each line in the time domain indicates a slot boundary. 9001 indicates a downlink region. 9002 indicates a flexible region. 9003 indicates an uplink region.

[0329] Region indicated by 9000 includes a set of region 9001, 9002 and 9003. Region 9000 may be configured based on a slot configuration. For example, a slot configuration may include at least a downlink region, a flexible region and an uplink region. For example, a slot configuration may be configured such that the slot configuration starts at one UL-to-DL switching point. Further, the slot configuration may be configured such that the slot configuration ends at another UL-to-DL switching point. For example, a UL-to-DL switching point may be a point where a uplink region ends and a downlink region starts.

[0330] For example, a slot configuration may be repeated in the time domain. In Figure 9, a slot configuration comprising 3 downlink slots, one special slot and 1 uplink slot is repeated. Region 9000 is an instance of the slot configuration starting at slot#n and an Region 9010 is an instance of the slot configuration starting at slot#n+5. In Figure 9, repetition cycle of the slot configuration is 5 slots. [0331] 9011 indicates a downlink region. Further, 9012 indicates a flexible region.

Further, 9013 indicates an uplink region.

[0332] For example, a slot configuration may be represented by a combination of ‘D’, ‘U’ and ‘S’. ‘D’ indicates that a slot is a downlink slot. A downlink slot is a slot with downlink region. In Figure 9, slot#n, slot#n+l, slot#n+2, slot#n+5, slot#n+6 and slot#n+7 are downlink slots.

[0333] ‘U’ indicates that a slot is an uplink slot. An uplink slot is a slot with uplink region. In Figure 9, slot#n+4 and slot#n+9 are uplink slots.

[0334] ‘S’ indicates that a slot is a special slot. A special slot is a slot with at least two or more of a downlink regions, a flexible region and an uplink region. In Figure 9, slot#n+3 and slot#n+8 are special slots.

[0335] In Figure 9, the slot configuration may be also referred to as “DDDSU”. “DDDSU” means that the slot configuration comprises 3 downlink slots, 1 special slot and 1 uplink slot.

[0336] A configuration of special slot may be represented by “XDYFZU”. Here, X is the number of downlink symbols, Y is the number of flexible symbols and Z is the number of uplink symbols. For example, “10D2F2U” indicates that a special slot comprises 10 downlink symbols, 2 flexible symbols and 2 uplink symbols.

[0337] A downlink symbol is an OFDM symbol in a downlink region. A flexible symbol is an OFDM symbol in a flexible region. An uplink symbol is an OFDM symbol in an uplink region.

[0338] A slot configuration may be provided by RRC parameters. For example, a slot configuration may be configured by a common parameter included in system information such as SIB1. The common parameter may be also referred to as tdd-UL-DL- ConfigurationCommon.

[0339] For example, terminal device 1 may determine a reference subcarrier-spacing configuration u _ref and a first TDD pattern from the common parameter. The first TDD pattern includes one or more of T1 to T5. T1 is a configuration period P in milliseconds provided by referenceSubcarrierSpacing. T2 is the number d _slots of slots indicating consecutive downlink slots provided by nrofDownlinkSlots. T3 is the number d _sym of consecutive downlink symbols provided by nrofDownlinkSymbols. T4 is the number U _slots of consecutive uplink slots provided by nrofUplinkSlots. T5 is the number u _sym of consecutive uplink symbols provided by nrofUplinkSymbols.

[0340] Figure 10 is an example configuration of a slot configuration according to an aspect of the present embodiment. In Figure 10, a horizontal axis indicates time domain. In the time domain, slots are numbered from slot#n (slot with index n) in ascending order. Each line in the time domain indicates a slot boundary. 10000 indicates a slot configuration. In the slot configuration, first d _slots =2 slots as indicated by Region 10001 are configured as downlink slots. In the slot configuration, last u _slots =l slot as indicated by Region 10002 is configured as an uplink slot. In the slot configuration, first d _sym OFDM symbols starting at first OFDM symbol in a slot with index n+d _slots as indicated by Region 10003 is configured as downlink symbols. In the slot configuration, last u _sym OFDM symbols before first OFDM symbol in a slot with index n+S -U _slots as indicated by Region 10004 is configured as uplink symbols. In the slot configuration, the remaining OFDM symbols not indicated as either downlink region or uplink region as indicated by Region 1005 are flexible symbols. [0341] A slot configuration may be modified by a UE-specific parameter. The UE- specific parameter may be also referred to as tdd-UL-DL-ConfigurationDedicated.

[0342] If the UE-specific parameter is provided to terminal device 1, the UE-specific parameter may modify (or reconfigure) the slot configuration provided by the common parameter. For example, the UE-specific parameter may modify (or reconfigure) flexible region in the slot configuration.

[0343] For example, terminal device 1 may determine a list including a set of slot reconfigurations by the UE-specific parameter. In each slot reconfiguration in the set, at least one or both of an index of a slot and an indication of TDD pattern of the slot may be provided. The indication may indicate one out of ‘all DL’, ‘all UL’ and ‘explicit’. In a case that ‘all DL’ is indicated for the slot, the slot configuration in the slot is reconfigured as downlink region. In a case that ‘all UL’ is indicated for the slot, the slot configuration in the slot is reconfigured as uplink region. In a case that ‘explicit’ is indicated for the slot, the slot configuration in the slot is reconfigured by explicit indication corresponding to ‘explicit’. Indication ‘explicit’ corresponds to information indicating a TDD pattern in a slot. The information includes information indicating the number of downlink symbols starting at the beginning of the slot and information indicating the number of uplink symbols ending at the end of the slot. The remaining OFDM symbols between downlink symbols and uplink symbols are flexible symbols.

[0344] Terminal device 1 may receive a physical signal if terminal device 1 is configured by a higher layer or indicated by a DCI format to receive the physical signal in the downlink region. [0345] Terminal device 1 may transmit a physical signal if terminal device 1 is configured by a higher layer or indicated by a DCI format to transmit the physical signal in the uplink region.

[0346] In a case that monitoring of DCI format 2_0 is not configured by a higher layer, terminal device 1 may receive a physical signal if terminal device 1 is indicated by a DCI format scheduling the physical channel to receive in the downlink region or the flexible region.

[0347] In a case that monitoring of DCI format 2_0 is not configured by a higher layer, terminal device 1 may transmit a physical signal if terminal device 1 is indicated by a DCI format scheduling the physical signal to transmit in the uplink region or the flexible region.

[0348] In a case that monitoring of DCI format 2_0 is configured by a higher layer, terminal device 1 may determine whether to receive a physical signal or not at least based on indication in the DCI format 2_0.

[0349] In a case that monitoring of DCI format 2_0 is configured by a higher layer, terminal device 1 may determine whether to transmit a physical signal or not at least based on indication in the DCI format 2_0.

[0350] Configuration regarding monitoring of DCI format 2_0 may include at least one or more of SI to S3. SI is an identifier of a serving cell. S2 is information indicating bit location of field for index of a slot format indicator. S3 is a set of slot format combinations. Here, each slot format combination may include one or more slot formats. Each of slot format combination may include an index of a slot format indicator. Each slot format may indicate a TDD pattern within a slot. For example, slot format#0 indicates that all OFDM symbols in a slot are downlink symbol. For example, slot format#! indicates that all OFDM symbols in a slot are uplink symbol. For example, one slot format indicates that first 9 OFDM symbols in a slot are downlink symbol, next 3 OFDM symbols in the slot are flexible symbol and remaining 2 OFDM symbols are uplink symbol. For example, one slot format indicates that terminal device 1 interpret as if monitoring of DCI format 2_0 is not configured. Other TDD patterns in a slot are not precluded.

[0351] In a case that terminal device 1 detects a DCI format 2_0 in a first slot, terminal device 1 applies a slot format combination indicated through an index of slot format indicator in the DCI format 2_0. For example, the slot format combination may be applied to slots starting at the first slot.

[0352] At least based on an indication in DCI format 2_0, behavior of PUSCH transmission may be controlled. For example, a PUSCH transmission may be repetition of a PUSCH instance where the PUSCH instance is defined within a slot.

[0353] A PUSCH instance may be a unit of baseband signal generation. Here, the baseband signal generation may be performed by the baseband unit 13.

[0354] Figure 11 is an example configuration of the baseband unit 13 in the wireless transmission unit 10a according to an aspect of the present embodiment. The baseband unit 13 may include at least a part or all of Encoder 12000, Scrambler 11001, Modulator 11002, Layer mapper 11003, Transform precoder 11004, Precoder 11005, Resource element mapper 11006 and Time-continuous signal generator 11007.

[0355] A transport block may be provided to Encoder 12000 from a higher layer. For example, a transport block may be provided to Encoder 12000 through UL-SCH from MAC layer processing unit 15. Encoder 12000 processes the transport block into a sequence b of coded bits. The sequence of the coded bits may be provided to Scrambler 11001. An element in position k of the sequence b may be referred to as b(k). The position k is in the range from 0 to Mbit-1. The position k is represented by an integer number. The M _bit represents the length of the sequence b.

[0356] For example, Scrambler 11001 may scramble the sequence b of the coded bits by using a pseudo-random code c. For example, the element b(k) may be scrambled by an element c(k) in position k ofthe pseudo-random code c. For example, Scrambler 11001 may output a sequence b ^a by calculating b ^a (k) = mod(b(k)+c(k), 2). The b ^a (k) is an element in position k of the sequence b ^a . In a case that the baseband unit 13 doesn’t include Scrambler 11001, the sequence b of the coded bits may be input to the b _a .

[0357] The pseudo-random code c may be a sequence of bits generated by Scrambler 11001. For example, the pseudo-random code c may be generated by an equation with initialization variable. The initialization variable may determine or control an output from the equation. The initialization variable may be determined at least based on RNTI used for scheduling an uplink transmission conveying the transport block.

[0358] For example, Modulator 11002 may perform a modulation to the sequence b _a and generate a sequence d of complex-valued symbols. An element in position j of the sequence d is referred to as d(j). The position ] is in the range from 0 to M _symb -1- The position j is represented by an integer number. The M _symb represents the length of the sequence d. In a case that the baseband unit 13 doesn’t include Modulator 12002, the sequence b ^a of the coded bits may be input to the d.

[0359] For example, the modulation may be 2/pi BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), 16QAM (Quadrature Amplitude Modulation), 64QAM or 256QAM. [0360] For example, Layer mapper 11003 may perform layer mapping to the sequence d. After layer mapping, N _v sequences each with length M ^layer _symb are generated. The N _v is the number of layers for the PUSCH. The V ^th sequence in the N _v sequences is referred to as x ^(v) . An element in position h of the sequence x ^(v) is referred to as x ^(v) (h). The position h is in the range from 0 to M ^layer _sym b-1. The position h is represented by an integer number. In a case that the number N _v is 1, Layer mapper 11003 may not perform layer mapping. In a case that the layer mapping is not performed to the sequence d, the sequence d may be input to x ⁽⁰⁾

[0361] For example, Transform precoder 11004 may perform a transform precoding to the sequence x ^(v) and generate a sequence y ^(v) In a case that the transform precoding is not performed to the sequence x ^(v) the sequence x ^(v) may be input to the sequence ^(v) .

[0362] For example, Precoder 11005 may perform a precoding to the sequence y ^(v) After the precoding, N _p sequences each with length M ^layer _sym b are generated. The N _p is the number of antenna ports for the PUSCH. The p ^th sequence in the N _p sequences is referred to as z ^(p) An element in position h of the sequence z ^(p) is referred to as z ^(p) (h). In a case that the number N _p is 1 , Precoder 11005 may not perform the precoding. In a case that the precoding is not performed to the sequence y ^(v) the sequence y ^(v) may be input to z ^(p) .

[0363] For example, Resource element mapper 11006 may perform a RE mapping. In a RE mapping, a group of elements z(h) = [z ⁽⁰⁾ (h),. . ., z ^{(Np -1)} (h)] is mapped to a resource element.

[0364] For example, Time-continuous signal generator 11007 may perform a time- continuous signal generation based on contents in the resource elements. The contents in the resource elements are determined based on the RE mapping. The time-continuous signal generated by Time-continuous signal generator 11007 is provided to RF unit 12. [0365] The baseband unit 33 may include corresponding components for reception of the PUSCH as the baseband unit 13.

[0366] Figure 12 is an example configuration of Encoder 12000 according to an aspect of the present embodiment. Encoder 12000 may include at least a part or all of CRC addition unit 12001, CB segmentation unit 12002, Encoding unit 12003, Rate matching unit 12004 and Multiplexing unit 12005.

[0367] For example, a transport block input to Encoder 12000 is an input to CRC addition unit 12001. In CRC addition unit 12001, a CRC sequence is added to the transport block. A bit sequence after CRC sequence addition is input to Code block segmentation unit 12002. In a case that a CRC sequence is not added to the transport block, the transport block is input to Code block segmentation unit 12002.

[0368] For example, a sequence input to Code block segmentation unit 12002 is segmented into multiple code blocks in a case that the length of the sequence is larger than a certain value. In a case that the sequence is segmented into multiple code blocks, a CRC sequence is added to each code block. Each code block after the CRC sequence addition is input to Encoding unit 12003. In a case that the sequence is not segmented into multiple code blocks, a single code block is input to Encoding unit 12003. In a case that the sequence is not segmented into multiple code blocks, a CRC sequence is not added to the single code block. In a case that the sequence is not segmented into multiple code blocks, the single code block without addition of a CRC sequence is input to Encoding unit 12003.

[0369] For example, a code block with index r (code block#r) input to Encoding unit 12003 is encoded by LDPC coding such as QC-LDPC (Quasi-Cyclic Low Density Parity Check) coding. The index r is in the range from 0 to C-l. The C is the number of code blocks determined in Code block segmentation unit 12002. Coded bits d ^r for the code block#r after LDPC coding is input to Rate matching unit 12004.

[0370] For example, Rate matching unit 12004 performs a bit-selection procedure. In the bit-selection procedure, the coded bits d ^r for the code block r is written into a circular buffer of length N _c b.

[0371] Figure 13 is an example of the bit-selection procedure according to an aspect of the present embodiment. In the bit-selection procedure, two values k and j are set to 0 as Step 0. Next, in Step 1, Rate matching unit 12004 checks if the value k is smaller than a rate matching output sequence length E _r . If the value k is smaller than the rate matching output sequence length E _r , Rate matching unit 12004 goes to Step 2. If the value k is not smaller than the rate matching output sequence length E _r , Rate matching unit 12004 terminates the bit-selection procedure.

[0372] Here, the rate matching output sequence length E _r represents the number of available bits for transmission of the code block#r. For example, the rate matching output sequence length E _r for code block#r may be calculated at least based on a part or all of modulation order Q _m , the number N _v of layers for the PUS CH, the number C’ and the number G. For example, the rate matching output sequence length E _r for code block r may be calculated by E _r = N _L Q _m floor(G/(NLQmC’)) or E _r = NLQ _m ceil(G/(NLQmC’)).

[0373] Here, the number C’ represents the number of code blocks. The number G represents the number of available bits for transmission of UL-SCH. For example, the number G may represent the number of available bits for transmission of UL-SCH in the PUSCH instance. [0374] In Step 2, Rate matching unit 12004 checks if d ^r (mod(ko+j, N _c b)) is not <NULL>. If d ^r (mod(ko+j, N _c b)) is not <NULL>, Rate matching unit 12004 goes to Step 3. If d ^r (mod(ko+j, N _cb )) is <NULL>, Rate matching unit 12004 goes to Step 5.

[0375] Here, “d ^r (mod(ko+j, N _c b)) is <NULL>” means <NULL> is set to d ^r (mod(k0+j, Ncb)). <NULL> may be set to some elements of d ^r when an element corresponds to a filler bit for LDPC coding.

[0376] Here, an element in position k of d ^r is referred to as d ^r (k).

[0377] In Step 3, Rate matching unit 12004 sets a value in d ^r (mod(ko+j, N _c b)) to e(k). The sequence e is a rate matching output sequence. An element in position k of the sequence e is referred to as e(k).

[0378] Here, ko represents a starting point for the circular buffer.

[0379] In Step 4, Rate matching unit 12004 increments a value k by one.

[0380] Step 5 is a sign of the end of Step 2.

[0381] In Step 6, Rate matching unit 12004 increments a value j by one.

[0382] Step 7 is a sign of the end of Step 1. Rate matching unit 12004 goes back to Step 1.

[0383] Figure 14 is an example of a circular buffer according to an aspect of the present embodiment. In the circular buffer, the coded bits d ^r are mapped clockwise starting at position indicated by RV0. Since the coded bits d _r includes systematic bits followed by parity bits, the systematic bits are mapped starting at the position indicated by RV0 and the parity bits are mapped starting at the end of the systematic bits. The region indicated by the upper right diagonal line is filled with the systematic bits. The region indicated by the lattice line is filled with the parity bits. [0384] In the bit-selection procedure, bits in the circular buffer are read out starting at the starting point ko with length E _r . The bits read out from the circular buffer are written into the rate matching output sequence e.

[0385] The starting point ko is determined based on the redundancy version indicated or determined by a redundancy version field in an uplink DCI format for dynamic scheduling.

[0386] For example, the starting point ko may be determined based on the redundancy version and an identification of an instance. For example, in a case that one DCI format schedules a repetition of a PUSCH, terminal device 1 may transmit multiple instances. For each instance, the starting point ko may be determined. For example, in a case that 8 instances (instance#0, instance#1, instance#2, instance#3, instance#4, instance#5, instance#6, instance#7) are scheduled by one DCI format, the starting point ko may be determined 8 times.

[0387] For example, a sequence of RV (redundancy version) may be provided to the terminal device 1. In a case that a sequence of RV is provided, a RV is allocated to each instance in the multiple instances based on the sequence. For example, in a case that the sequence [0, 2, 3 , 1 ] of length N _s is provided, (mod (n, N _s )+ 1 )* value in the sequence may be allocated to n ^th instance. The starting point k ₀ of n ^th instance may be determined based on the allocated RV for n ^th instance.

[0388] Figure 15 is an example configuration of first type repetition of a PUSCH scheduled by a DCI format in multiple slots according to an aspect of the present embodiment. In Figure 15, 15000 indicates a PDCCH with a DCI format which schedules a PUSCH with a first type repetition. It is assumed that the first type repetition is scheduled in slots starting at slot#n+3 in Figure 15. 15001 indicates an instance of the PUSCH in slot #n+3. Here, a value S indicates a starting OFDM symbol index within the slot for the instance 15001. Also, a value L indicates a length in terms of the number of OFDM symbols for the instance 15001. 6 instances indicated by 15002 to 15007 are followed by the instance 15001. Each instance is mapped within a slot. In Figure 15, it is assumed that the number K _rep of repetitions is 7.

[0389] A TDRA field in the DCI format may provide a value S and a value L.

[0390] In Figure 15, the S is applied to all the instances for the PUSCH. For example, all the instances apply the same starting OFDM symbol index within a slot. In Figure 15, the L is applied to all the instances for the PUSCH. For example, all the instances apply the same length in terms of the number of OFDM symbols.

[0391] In a first type repetition, multiple instances for a PUSCH may be allocated on K _rep continuous slots starting at a slot determined by a DCI format scheduling the PUSCH. For example, in a case that a DCI format scheduling the PUSCH includes a TDRA field, the TDRA field may provide a value K for determining the starting slot for the PUSCH. For example, the value K is in unit of slots. For example, the terminal device 1 may determine the starting slot as slot#(n+K) in a case that a PDCCH including the DCI format is detected in slot#n. In a case that the DCI format doesn’t include a TDRA field, the value K may be provided by a RRC layer through a RRC parameter.

[0392] A sequence of RV for the first type repetition may be provided to the terminal device 1. For example, the sequence may be provided by a RRC layer through a RRC parameter. In a case that a sequence of RV is provided for the first type repetition, (mod (n, N _s )+1) ^th value in the sequence may be allocated to n ^th instance. Here, an index may be provided to each instance for the PUSCH in ascending order in the time domain. [0393] For a first type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot configuration, transmission of the instance may be omitted (or dropped, cancelled, not transmitted).

[0394] For a first type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot format, transmission of the instance may be omitted.

[0395] For a first type repetition, in a case that an instance overlaps with another uplink signal with a higher priority than the priority for the PUSCH, transmission of the instance may be omitted. For example, the uplink signal may be a second PUSCH with higher priority than the priority of the PUSCH. For example, the priority for a PUSCH may be provided by a DCI format scheduling the PUSCH.

[0396] Figure 16 is an example configuration of second type repetition of a PUSCH scheduled by a DCI format in multiple slots according to an aspect of the present embodiment. In Figure 16, 16000 indicates a PDCCH with a DCI format which schedules a PUSCH with a second type repetition. It is assumed that the second type repetition is scheduled in slots starting at slot#n+3. 16001 indicates an instance of the PUSCH in slot #n+3. Here, a value S indicates a starting OFDM symbol index within the slot for the instance. Also, a value L indicates a length in terms of the number of OFDM symbols for the instance. 3 instances indicated by 16002 to 16004 are followed by the instance 16001. Each instance is mapped within a slot. In Figure 16, it is assumed that the number K _rep of repetitions is 4.

[0397] In Figure 16, S is applied to all instances for the PUSCH. For example, all instances apply the same starting OFDM symbol index within a slot. In Figure 16, L is applied to all instances for the PUSCH. For example, all instances apply the same length in terms of the number of OFDM symbols. [0398] In a second type repetition, the multiple instances for a PUSCH may be allocated on K _rep continuous available slots starting at a slot determined by a DCI format scheduling the PUSCH. For example, in a case that a DCI format scheduling the PUSCH includes a TDRA field, the TDRA field may provide a value K for determining the starting slot for the PUSCH. For example, the value K is in unit of slots. For example, in a case that the terminal device 1 may determine the starting slot as slot#(n+K). In a case that the DCI format doesn’t include a TDRA field, the value K may be provided by a RRC layer through a RRC parameter.

[0399] In a second type repetition, K _rep continuous available slots may be determined by a slot configuration. For example, a slot may be available in a case that a set of OFDM symbols allocated for an instance in the slot doesn’t overlap with any downlink symbol which is determined by a slot configuration. For example, a slot may be available in a case that a set of OFDM symbols determined by a value S and a value L in the slot doesn’t overlap with any downlink symbol which is determined by a slot configuration. The value S and the value L may be provided by the TDRA field in the DCI format. In Figure 16, slot#n+3 is available for a second type repetition since the set of OFDM symbols allocated for the instance 16001 doesn’t overlap with 9001. In other words, slot#n+3 is available for a second type repetition since each OFDM symbol allocated for the instance 16001 overlaps with 9002 or 9003. In Figure 16, slot#n+4 is available for a second type repetition since the set of OFDM symbols allocated for the instance 16002 doesn’t overlap with 9001. In other words, slot#n+4 is available for a second type repetition since each OFDM symbols allocated for the instance 16002 overlaps with 9003. In Figure 16, slot#n+5 is not available for a second type repetition since the set of OFDM symbols determined by the value S and the value L overlaps with 9011. In other words, slot#n+5 is not available for a second type repetition since some OFDM symbols determined by the value S and the value L doesn’t overlap with 9002 or 9003.

[0400] A sequence of RV may be provided for the second type repetition to the terminal device 1. For example, the sequence may be provided by a RRC layer through a RRC parameter. In a case that a sequence of RV is provided for the second type repetition, (mod (n, N _s )+1) ^th value in the sequence may be allocated to n ^th instance. Here, an index may be provided to each instance for the PUSCH in ascending order in the time domain. [0401] For example, a first sequence of RV and a second sequence of RV may be provided to the terminal device 1. For example, the first sequence may be used for a first type repetition. For example, the second sequence may be used for a second type repetition.

[0402] For example, the first sequence may be provided by a RRC layer through a first RRC parameter. For example, the second sequence may be provided by a RRC layer through a second RRC parameter which is different from the first RRC parameter.

[0403] For a second type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot configuration, transmission of the instance may be omitted. On the other hand, For a second type repetition, there may be no case that an instance overlaps with a downlink symbol determined by a slot configuration since the collision handling with the downlink symbol by the slot configuration may have been done already in a procedure of determining the K _rep continuous available slots. Therefore, for a second type repetition, transmission of the instance may not be omitted based on the slot configuration. For example, for a second type repetition, the terminal device 1 may not determine, based on the slot configuration, whether an instance is omitted or not. For example, the terminal device 1 may not perform a process of determining, based on the slot configuration, whether an instance is omitted or not.

[0404] For a second type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot format, transmission of the instance may be omitted.

[0405] For a second type repetition, in a case that an instance overlaps with another uplink signal with a higher priority than the priority for the PUSCH, transmission of the instance may be omitted. For example, the uplink signal may be a second PUSCH with higher priority than the priority of the PUSCH. For example, the priority for a PUSCH may be provided by a DCI format scheduling the PUSCH.

[0406] A third type repetition is described with Figure 16 assuming K _rep = 3.

[0407] In a third type repetition, multiple instances for a PUSCH may be allocated on continuous available slots starting at a slot determined by a DCI format scheduling the PUSCH.

[0408] In a third type repetition, the continuous available slots may be determined by a slot configuration. For example, a slot may be available in a case that a set of OFDM symbols allocated for an instance in the slot doesn’t overlap with any downlink symbol which is determined by a slot configuration. For example, a slot may be available in a case that a set of OFDM symbols determined by a value S and a value L provided by the TDRA field in the DCI format in the slot doesn’t overlap with any downlink symbol which is determined by a slot configuration. In Figure 16, slot#n+3 is available for a third type repetition since the set of OFDM symbols allocated for the instance 16001 doesn’t overlap with 9001. In other words, slot#n+3 is available for a third type repetition since each OFDM symbol allocated for the instance 16001 overlaps with 9002 or 9003. In Figure 16, slot#n+4 is available for a third type repetition since the set of OFDM symbols allocated for the instance 16002 doesn’t overlap with 9001. In other words, slot#n+4 is available for a third type repetition since each OFDM symbol allocated for the instance 16002 overlaps with 9003. In Figure 16, slot#n+5 is not available for a third type repetition since the set of OFDM symbols determined by the value S and the value L overlaps with 9011. In other words, slot#n+5 is not available for a third type repetition since some OFDM symbols determined by the value S and the value L doesn’t overlap with 9002 or 9003.

[0409] A sequence of RV may be provided for the third type repetition to the terminal device 1. For example, the sequence may be provided by a RRC layer through a RRC parameter. In a case that a sequence of RV is provided for the third type repetition, (mod (n, N _s )+1) ^th value in the sequence may be allocated to n ^th instance. For example, a first sequence of RV and a third sequence of RV may be provided to the terminal device 1. For example, the first sequence may be used for a first type repetition. For example, the third sequence may be used for a third type repetition.

[0410] For example, the first sequence may be provided by a RRC layer through a first RRC parameter. For example, the third sequence may be provided by a RRC layer through a third RRC parameter which is different from the first RRC parameter.

[0411] For a third type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot configuration, transmission of the instance may be omitted. On the other hand, For a third type repetition, there may be no case that an instance overlaps with a downlink symbol determined by a slot configuration since the collision handling with the downlink symbol by the slot configuration may have been done already in a procedure of determining the continuous available slots. Therefore, for a third type repetition, transmission of the instance may not be omitted based on the slot configuration. For example, for a third type repetition, the terminal device 1 may not determine, based on the slot configuration, whether an instance is omitted or not. For example, the terminal device 1 may not perform a process of determining, based on the slot configuration, whether an instance is omitted or not.

[0412] For a third type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot format, transmission of the instance may be omitted.

[0413] For a third type repetition, in a case that an instance overlaps with another uplink signal with a higher priority than the priority for the PUSCH, transmission of the instance may be omitted. For example, the uplink signal may be a second PUSCH with higher priority than the priority of the PUSCH. For example, the priority for a PUSCH may be provided by a DCI format scheduling the PUSCH.

[0414] For a third type repetition, first K _rep instances are determined for the PUSCH transmission. For example, in a case that no instances are omitted, the terminal device may determine that the instance 16001, 16002, and 16003 as the first K _re p instances. For example, in a case that the instance 16002 is omitted due to the collision with the high priority signal, the terminal device determines that the instance 16001, 16003 and 16004 as the first K _rep instances. For example, in a case that the instance 16003 is omitted due to the collision with the high priority signal, the terminal device determines that the instance 16001, 16002 and 16004 as the first K _rep instances.

[0415] A fourth type repetition is described with Figure 16 assuming K _rep = 3.

[0416] In a fourth type repetition, multiple instances for a PUSCH may be allocated on continuous available slots starting at a slot determined by a DCI format scheduling the

PUSCH. [0417] In a fourth type repetition, the continuous available slots may be determined by a slot configuration. For example, a slot may be available in a case that a set of OFDM symbols allocated for an instance in the slot doesn’t overlap with any downlink symbol which is determined by a slot configuration. For example, a slot may be available in a case that a set of OFDM symbols determined by a value S and a value L provided by the TDRA field in the DCI format in the slot doesn’t overlap with any downlink symbol which is determined by a slot configuration. In Figure 16, slot#n+3 is available for a fourth type repetition since the set of OFDM symbols allocated for the instance 16001 doesn’t overlap with 9001. In other words, slot#n+3 is available for a fourth type repetition since each OFDM symbol allocated for the instance 16001 overlaps with 9002 or 9003. In Figure 16, slot#n+4 is available for a fourth type repetition since the set of OFDM symbols allocated for the instance 16002 doesn’t overlap with 9001. In other words, slot#n+4 is available for a fourth type repetition since each OFDM symbol allocated for the instance 16002 overlaps with 9003. In Figure 16, slot#n+5 is not available for a fourth type repetition since the set of OFDM symbols determined by the value S and the value L overlaps with 9011. In other words, slot#n+5 is not available for a fourth type repetition since some OFDM symbols determined by the value S and the value L doesn’t overlap with 9002 or 9003.

[0418] Before determining a RV for each instance, the terminal device 1 may determine whether one or more instances are omitted or not. For example, in a case that no instances are omitted, the terminal device may determine that the instance 16001, 16002, and 16003 as the first K _rep instances. For example, in a case that the instance 16002 is omitted due to the collision with the high priority signal, the terminal device determines that the instance 16001, 16003 and 16004 as the first K _rep instances. For example, in a case that the instance 16003 is omitted due to the collision with the high priority signal, the terminal device determines that the instance 16001, 16002 and 16004 as the first K _re p instances.

[0419] A sequence of RV may be provided for the fourth type repetition to the terminal device 1. For example, the sequence may be provided by a RRC layer through a RRC parameter. In a case that a sequence of RV is provided for the fourth type repetition, (mod (n, N _s )+1) ^th value in the sequence may be allocated to n ^th instance within the first K _rep instances. For example, a first sequence of RV and a fourth sequence of RV may be provided to the terminal device 1. For example, the first sequence may be used for a first type repetition. For example, the fourth sequence may be used for a fourth type repetition. [0420] For example, the first sequence may be provided by a RRC layer through a first RRC parameter. For example, the fourth sequence may be provided by a RRC layer through a fourth RRC parameter which is different from the first RRC parameter.

[0421] For a fourth type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot configuration, transmission of the instance may be omitted. On the other hand, for a fourth type repetition, there may be no case that an instance overlaps with a downlink symbol determined by a slot configuration since the collision handling with the downlink symbol by the slot configuration may have been done already in a procedure of determining the continuous available slots. Therefore, for a fourth type repetition, transmission of the instance may not be omitted based on the slot configuration. For example, for a fourth type repetition, the terminal device 1 may not determine, based on the slot configuration, whether an instance is omitted or not. For example, the terminal device 1 may not perform a process of determining, based on the slot configuration, whether an instance is omitted or not. [0422] For a fourth type repetition, in a case that an instance overlaps with a downlink symbol determined by a slot format, transmission of the instance may be omitted.

[0423] For a fourth type repetition, in a case that an instance overlaps with another uplink signal with a higher priority than the priority for the PUSCH, transmission of the instance may be omitted. For example, the uplink signal may be a second PUSCH with higher priority than the priority of the PUSCH. For example, the priority for a PUSCH may be provided by a DCI format scheduling the PUSCH.

[0424] For a fourth type repetition, the first K _rep instances are transmitted for the PUSCH transmission.

[0425] Figure 17 is an example configuration of first type repetition of a PUSCH with a configured grant in multiple slots according to an aspect of the present embodiment. In Figure 17, 17010 indicates a period for a configured grant. 17011 indicates a period for a configured grant. Periods 17010 and 17011 are configured periodically. A configured grant occurs in a starting OFDM symbol of the period 17010. In a case that a configured grant occurs in a starting OFDM symbol of the period 17010, it is assumed that the first type repetition is scheduled in slots starting at slot#n+3 where slot#n+3 includes the starting OFDM symbol. 17001 indicates an instance of the PUSCH in slot #n+3. Here, a value S indicates a starting OFDM symbol index within the slot for the instance 17001. Also, a value L indicates a length in terms of the number of OFDM symbols for the instance 17001. 5 instances indicated by 17002 to 17006 are followed by the instance 17001. Each instance is mapped within a slot. In F igure 17, it is assumed that the number K _rep of repetitions is 6.

[0426] Here, the PUSCH is associated with the period 17010. Also, the PUSCH is associated with the instances 17001 to 17006. [0427] For example, a value S and a value L may be provided by a RRC layer via a RRC parameter. For example, a value S and a value L may be provided by a TDRA field in a DCI format which activates a configured grant operation.

[0428] 17007 indicates an instance of another PUSCH. The instance 17007 is not a part of repetitions for the PUSCH within the period 17010. The instance 17007 is a first instance for another PUSCH within the period 17011. Here, a period may define a time occasion which includes a number of repetitions for a single PUSCH. For example, if two instances are included in different periods, the two instances are associated with different PUSCH.

[0429] Here, another PUSCH is associated with the period 17011. Also, another PUSCH is associated with the instances 17001 to 17006.

[0430] A PUSCH with instances which occur within a period is associated with the period. The PUSCH is associated with the instances.

[0431] In Figure 17, the S is applied to all the instances for the PUSCH. For example, all the instances apply the same starting OFDM symbol index within a slot. In Figure 17, the L is applied to all the instances for the PUSCH. For example, all the instances apply the same length in terms of the number of OFDM symbols.

[0432] In a first type repetition, multiple instances for a PUSCH may be allocated on K _rep continuous slots starting at a slot including a starting OFDM symbol of a period.

[0433] Figure 18 is an example configuration of second type repetition of a PUSCH with a configured grant in multiple slots according to an aspect of the present embodiment. In Figure 18, 18001 indicates an instance of the PUSCH in slot #n+3. Here, a value S indicates a starting OFDM symbol index within the slot for the instance. Also, a value L indicates a length in terms of the number of OFDM symbols for the instance. 2 instances indicated by 18002 and 18003 are followed by the instance 18001. Each instance is mapped within a slot.

[0434] In Figure 18, it is assumed that the number K _rep of repetitions is 4. On the other hand, the instance 18004 is not associated with the PUSCH. The instance 18004 is a first instance associated with another PUSCH within the period 17011.

[0435] For example, for a second type repetition, a set of instances for a PUSCH associated with a period may be determined based on the number K _rep and the period. For example, in a case that an instance for a PUSCH is out of the period associated with the PUSCH, the instance may be excluded from the set of instances for the PUSCH. For example, the K _rep indicates a maximum value for the number of instances for a PUSCH and instances are mapped within the period such that the number of the instances doesn’t exceed the number K _rep .

[0436] In Figure 18, a value S is applied to all instances for the PUSCH. For example, all instances apply the same starting OFDM symbol index within a slot. In Figure 18, a value L is applied to all instances for the PUSCH. For example, all instances apply the same length in terms of the number of OFDM symbols.

[0437] In a second type repetition, the multiple instances for a PUSCH may be allocated on continuous available slots starting at a slot including a starting OFDM symbol of a period associated with the PUSCH.

[0438] A third type repetition is described with Figure 18 assuming K _rep = 4.

[0439] In a third type repetition, multiple instances for a PUSCH may be allocated on continuous available slots starting at a slot including a starting OFDM symbol of the period associated with the PUSCH. [0440] For example, for a third type repetition, a set of instances for a PUSCH associated with a period may be determined based on the number K _rep and the period. For example, in a case that an instance for a PUSCH is out of the period associated with the PUSCH, the instance may be excluded from the set of instances for the PUSCH. For example, the K _rep indicates a maximum value for the number of instances for a PUSCH and instances are mapped within the period such that the number of the instances doesn’t exceed the number K _rep .

[0441] A fourth type repetition is described with Figure 16 assuming K _rep = 4.

[0442] In a fourth type repetition, multiple instances for a PUSCH may be allocated on continuous available slots starting at a slot including a starting OFDM symbol of the period associated with the PUSCH.

[0443] Figure 19 shows an example of a method for a UE. The method may comprise acquiring a first RRC parameter (Step 1901) and transmitting a PUSCH in multiple slots (Step 1902). If the first RRC parameter is set to a first value, conditions in a slot format procedure may not be used for determination of the multiple slots. If the first RRC parameter is set to a second value, the conditions in the slot format procedure may be used for the determination of the multiple slots.

[0444] Figure 20 shows an example of a method for a base station is described. The method may comprise sending a first RRC parameter (Step 2001) and receiving a PUSCH in multiple slots (Step 2002). If the first RRC parameter is set to a first value, conditions in a slot format procedure may not be used for determination of the multiple slots. If the first RRC parameter is set to a second value, the conditions in the slot format procedure may be used for the determination of the multiple slots. [0445] Each of a program running on the base station device 3 and the terminal device 1 according to an aspect of the present invention may be a program that controls a Central Processing Unit (CPU) and the like, such that the program causes a computer to operate in such a manner as to realize the functions of the above-described embodiment according to the present invention. The information handled in these devices is transitorily stored in a Random-Access-Memory (RAM) while being processed. Thereafter, the information is stored in various types of Read-Only- Memory (ROM) such as a Flash ROM and a Hard- Disk-Drive (HDD), and when necessary, is read by the CPU to be modified or rewritten. [0446] Note that the terminal device 1 and the base station device 3 according to the above-described embodiment may be partially achieved by a computer. In this case, this configuration may be realized by recording a program for realizing such control functions on a computer-readable recording medium and causing a computer system to read the program recorded on the recording medium for execution.

[0447] Note that it is assumed that the "computer system" mentioned here refers to a computer system built into the terminal device 1 or the base station device 3, and the computer system includes an OS and hardware components such as a peripheral device. Furthermore, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, and the like, and a storage device built into the computer system such as a hard disk.

[0448] Moreover, the "computer-readable recording medium" may include a medium that dynamically retains a program for a short period of time, such as a communication line that is used to transmit the program over a network such as the Internet or over a communication line such as a telephone line, and may also include a medium that retains a program for a fixed period of time, such as a volatile memory within the computer system for functioning as a server or a client in such a case. Furthermore, the program may be configured to realize some of the functions described above, and also may be configured to be capable of realizing the functions described above in combination with a program already recorded in the computer system.

[0449] Furthermore, the base station device 3 according to the above-described embodiment may be achieved as an aggregation (an device group) including multiple devices. Each of the devices configuring such an device group may include some or all of the functions or the functional blocks of the base station device 3 according to the above-described embodiment. The device group may include each general function or each functional block of the base station device 3. Furthermore, the terminal device 1 according to the above-described embodiment can also communicate with the base station device as the aggregation.

[0450] Furthermore, the base station device 3 according to the above-described embodiment may serve as an Evolved Universal Terrestrial Radio Access Network (E- UTRAN) and/or NG-RAN (Next Gen RAN, NR-RAN). Furthermore, the base station device 3 according to the above-described embodiment may have some or all of the functions of a node higher than an eNodeB or the gNB.

[0451] Furthermore, some or all portions of each of the terminal device 1 and the base station device 3 according to the above-described embodiment may be typically achieved as an LSI which is an integrated circuit or may be achieved as a chip set. The functional blocks of each of the terminal device 1 and the base station device 3 may be individually achieved as a chip, or some or all of the functional blocks may be integrated into a chip. Furthermore, a circuit integration technique is not limited to the LSI, and may be realized with a dedicated circuit or a general-purpose processor. Furthermore, in a case that with advances in semiconductor technology, a circuit integration technology with which an LSI is replaced appears, it is also possible to use an integrated circuit based on the technology.

[0452] Furthermore, according to the above-described embodiment, the terminal device has been described as an example of a communication device, but the present invention is not limited to such a terminal device, and is applicable to a terminal device or a communication device of a fixed-type or a stationary-type electronic device installed indoors or outdoors, for example, such as an Audio-Video (AV) device, a kitchen device, a cleaning or washing machine, an air-conditioning device, office equipment, a vending machine, and other household devices.
