BRIEF SUMMARY [0013] Disclosed herein are apparatus and methods to operate a communication device (UE) to indicate a TCI state ID or TCI state IDs in a beam. According to an aspect, the gNB can use a 8211594.1 DCI format such as DCI format 1_1 or DCI format 1_2 to dedicatedly indicate one or more TCI states to a UE. Such a DCI format is not configured to schedule downlink PDSCH assignment but is dedicated to indicate TCI state(s). In some embodiments, the UE determines whether a received DCI format is a dedicated DCI-based TCI state indication, and transmits a HARQ- ACK information in response to successful reception of a dedicated DCI-based TCI state indication. If a UE receives a dedicated DCI-based TCI state indication correctly, the UE may apply the indicated TCI state(s) on PDCCH/PDSCH reception and/or PUSCH/PUCCH transmission. [0014] Some aspects are directed to a method of operating a wireless communication device to indicate one or more TCI states of a beam. The method may comprise receiving a Downlink Control Information (DCI) format; determining whether the received DCI format is a TCI state indication configured to indicate the one or more TCI states; and upon a determination that the received DCI format is a TCI state indication, decoding the one or more TCI states from the received DCI format. [0015] In some embodiments, the DCI format is a DCI format 1_1 or DCI format 1_2. In some embodiments, the TCI state indication is a dedicated TCI state indication that is not associated with a DL assignment. In some embodiments, the TCI state indication is not configured to schedule a Physical Downlink Shared Channel (PDSCH) transmission. [0016] In some embodiments, the act of determining whether the received DCI format is a TCI state indication comprises: (A) determining whether a cyclic redundancy check (CRC) of the DCI format is scrambled with a Radio Network Temporary Identifier (RNTI); (B) determining whether one or more DCI fields in the DCI format have one or more values that meet a preset criteria; and (C) providing a determination the received DCI format is a TCI state indication when a result of act (A) and a result of act (B) are both positive. [0017] In some embodiments, act (A) comprises determining whether a cyclic redundancy check (CRC) of the DCI format is scrambled with a Configured Scheduling RNTI (CS-RNTI), and preferably determining whether a CRC of the DCI format is scrambled with a TCI-RNTI.

[0019] In some embodiments, the method further comprises in response to a determination that the received DCI format is a TCI state indication, transmitting an acknowledgement indicating that the TCI state indication is received correctly. Transmitting the acknowledgement may comprise transmitting an HARQ-ACK, and may comprise determining a time location for transmission of the HARQ-ACK based on a time location when the DCI format is received. [0020] Some aspects are directed to a communication device comprising a receiving unit adapted to receive a wireless signal comprising a DCI format; and a processor adapted to determine whether the received DCI format is a dedicated DCI-based TCI state indication that is configured to indicate one or more TCI states of a beam in the wireless signal.

Beam indication designs may be used for common-beam mode operations to indicate beam characteristics for a single common beam that is reused by multiple channels without the need for repeated control signal signaling to tell UE which beam to assume in subsequent transmission. Beam indication may be used to indicate one or more characteristics such as TCI-states of a common beam for the UE. The common beam may be a beam for multiple uplink channels, downlink channels and reference signals. [0035] For PDCCH and PDSCH, the UE may be configured with M TCI-states in higher layer signaling as the candidate QCL configuration. For each CORESET for PDCCH transmission, the UE can be configured with one or more TCI-states semi-statically and if more than one TCI-states are configured, one MAC CE command is used to activate one of those TCI- states as the active Tx beam for PDCCH transmission. For PDSCH, one MAC CE activation command can activate up to 8 TCI-state and each TCI-state is mapped to one codepoint in the DCI scheduling PDSCH transmission. Then for each individual PDSCH transmission, the NW can dynamically indicate one of those up to 8 TCI-states through the scheduling DCI. [0036] The Tx beam information for CSI-RS transmission may be indicated through a TCI- state configured or indicated to a CSI-RS resource. For a periodic CSI-RS resource, the TCI- state is configured in RRC semi-statically. For a semi-persistent CSI-RS resource, the TCI-state can be configured in RRC semi-statically or indicated in the MAC CE message that activates the transmission of semi-persistent CSI-RS. For an aperiodic CSI-RS resource, the TCI-state is configured to the CSI-RS resource in the configuration of aperiodic CSI-RS trigger state in RRC. Then the gNB can use physical layer signaling to dynamically trigger the transmission of aperiodic CSI-RS transmission and also dynamically indicate the Tx beam information. [0037] For SRS transmission, the UE Tx beam may be configured or indicated through spatial relation info. For periodic SRS transmission, the spatial relation info is configured per SRS resource in RRC semi-statically. For aperiodic SRS transmission, the spatial relation info can be configured in RRC semi-statically in one method. As another method, the NW can use one MAC CE to update/indicate spatial relation info for a SRS resource, which thus provide more dynamic spatial relation info updating. For semi-persistent SRS transmission, the spatial relation info can be included in the MAC CE activation command that activates the transmission of semi-persistent SRS resource. [0038] For PUCCH transmission, the UE Tx beam may be configured through PUCCH spatial relation info. The UE is provided with one or more than one PUCCH spatial relation info configurations in RRCH semi-statically. Then for each PUCCH resource, the UE can be indicated with one PUCCH spatial relation info through a MAC CE activation command. [0039] In release 16, to reduce the number of MAC CE messages for indicating TCI-states for PDCCH and PDSCH, a method of using a single MAC CE message to indicate the same TCI state ID or same set of TCI state IDs for PDCCH or PDSCH in multiple CCs. [0040] The inventor has recognized that there are shortcomings associated with the current approaches of indicating beam used for PDCCH/PDSCH/CSI-RS/PUSCH/SRS/PUCCH through the framework of TCI-state for downlink transmission or spatial relation for uplink transmission. [0041] In NR release 15 and release 16, for PDCCH and PDSCH, the UE may be configured with M TCI-states in higher layer signaling as the candidate QCL configuration. For each CORESET for PDCCH transmission, the UE can be configured with one or more TCI-states semi-statically and if more than one TCI-states are configured, one MAC CE command is used to activate one of those TCI-states as the active Tx beam for PDCCH transmission. For PDSCH, one MAC CE activation command can activate up to 8 TCI-state and each TCI-state is mapped to one codepoint in the DCI scheduling PDSCH transmission. Then for each individual PDSCH transmission, the NW can dynamically indicate one of those up to 8 TCI-states through the scheduling DCI. [0042] The Tx beam information for CSI-RS transmission is indicated through a TCI-state configured or indicated to a CSI-RS resource. For a periodic CSI-RS resource, the TCI-state is configured in RRC semi-statically. For a semi-persistent CSI-RS resource, the TCI-state can be configured in RRC semi-statically or indicated in the MAC CE message that activates the transmission of semi-persistent CSI-RS. For an aperiodic CSI-RS resource, the TCI-state is configured to the CSI-RS resource in the configuration of aperiodic CSI-RS trigger state in RRC. Then the gNB can use physical layer signaling to dynamically trigger the transmission of aperiodic CSI-RS transmission and also dynamically indicate the Tx beam information. [0043] For SRS transmission, the UE Tx beam is configured or indicated through spatial relation info. For periodic SRS transmission, the spatial relation info is configured per SRS resource in RRC semi-statically. For aperiodic SRS transmission, the spatial relation info can be configured in RRC semi-statically, which is one method and another method is the NW can use one MAC CE to update/indicate spatial relation info for a SRS resource, which thus provide more dynamic spatial relation info updating. For semi-persistent SRS transmission, the spatial relation info can be included in the MAC CE activation command that activates the transmission of semi-persistent SRS resource. [0044] For PUCCH transmission, the UE Tx beam is configured through PUCCH spatial relation info. The UE is provided with one or more than one PUCCH spatial relation info configurations in RRCH semi-statically. Then for each PUCCH resource, the UE can be indicated with one PUCCH spatial relation info through a MAC CE activation command. [0045] In the specification for 5G NR Release 16, to reduce the number of MAC CE messages for indicating TCI-states for PDCCH and PDSCH, a method of using a single MAC CE message is used to indicate the same TCI state ID (identification) or a same set of TCI state IDs for PDCCH or PDSCH in multiple CCs. Overview of Dedicated DCI-Based TCI State Indication [0046] The inventor has recognized there are drawbacks to the beam indication designs using higher layer signals such as RRC or MAC CE to indicate beams for each channel or reference signals. For example, the latency and overhead of beam indication operation may be large. In a system with large number of users or high mobility users, very frequent beam switching could consume all the radio resource and thus impair the system performance. [0047] The inventor has recognized and appreciated that a physical-layer signaling based beam indication method can resolve such drawbacks due to the advantage of low signaling overhead and latency of physical layer control signaling. Aspects of the present disclosure are directed to using a dedicated DCI-based TCI state indication to indicate one or more TCI states to a UE that may provide such an advantage. [0048] According to an aspect, the gNB can use a first DCI format to dedicatedly indicate one or more TCI states of a beam to a UE. The first DCI format may be referred to as a TCI state indication. In some embodiments, the first DCI format is not associated with a DL assignment. For example, the first DCI format does not schedule any PDSCH transmission. As such, the use of a DCI format without DL assignment to indicate TCI state(s) can be referred to as using a dedicated DCI-based TCI state indication. Such a dedicated DCI-based TCI state indication may also be referred to as a dedicated TCI state indication, TCI state indication, TCI indication, unified TCI indication, indicating TCI state, etc. [0049] In some embodiments, the first DCI format used as dedicated TCI state indication may be DCI format 1_1 or DCI format 1_2. The gNB can use a first DCI format 1_1 or DCI format 1_2 to dedicatedly indicate one or more TCI states to a UE. The first DCI format 1_1 or DCI format 1_2 does not schedule any PDSCH transmission. [0050] In some embodiments, the dedicated DCI-based TCI state indication may be used to indicate a joint TCI state for both UL and DL, or multiple TCI states such as one for UL, one for DL, while other variations can also be used. [0051] One aspect relates to how the UE identifies a received DCI format as a dedicated TCI state indication. In the 5G NR specification, DCI formats such as 1_1 and 1_2 have otherwise been used for other purposes such as dynamic PDSCH scheduling, SPS scheduling activation, SPS scheduling release. Special designs in the DCI format may be provided to let UE know and verify if a DCI format is dedicated for the purpose of TCI state indication. [0052] FIG.1 is a schematic flow diagram illustrating an exemplary method 100 of operating a UE to communicate with a beam, in accordance with some embodiments. As shown at block 102 of FIG.1, the UE receives a DCI format and at block 104 makes a determination whether the received DCI format is a dedicated TCI state information. Upon a positive determination, the UE at block 106 then decodes one or more TCI states from the DCI format. Method 100 may be part of a common-beam mode operation with a common beam, and the common beam may be a beam for multiple uplink channels, downlink channels and reference signals. [0053] The UE may determine if a received DCI format is a dedicated TCI state indication in any number of ways. In some embodiments, the determination is made based on whether a pattern of criteria is met by the DCI format. In some embodiments, the criteria comprise scrambling of a cyclic redundancy check (CRC) of the DCI format with an RNTI, such as a CS- RNTI or a TCI-RNTI. In some embodiments, CS-RNTI is reused for purpose of scrambling CRC of the dedicated TCI state indication, such that TCI-RNTI remain available for other purposes. [0054] The criteria for determining if a DCI format is a dedicated TCI state indication may further comprise the existence of one or more specified bits at one or more predetermined DCI fields of the DCI format. [0055] In some embodiments, merely relying on a scrambled CRC may not be sufficient to narrow down the determination that the received DCI format is a dedicated TCI state indication, and the criteria comprises a combination of a CRC scrambled with a RNTI value, and specified bit(s) in one or more DCI fields. Because DCI fields have many existing values for various purposes, in some embodiments, a pattern of specified bit(s) from multiple DCI fields must be matched for the UE to determine the DCI format is a dedicated TCI state indication. [0056] FIG.2 is a schematic flow diagram illustrating an exemplary process 204 of determining whether a received DCI format is a TCI state indication, in accordance with some embodiments. As shown at block 212 of FIG.2, the UE determines whether the CRC of the received DCI format is scrambled with a RNTI value. At block 214, the UE determines if a pattern of specified bit(s) from multiple DCI fields have values that meet a preset criteria. Only when results of both blocks 212 and 214 are positive, will the process proceed to block 216 to provide a determination the received DCI format is a TCI state indication. It should be appreciated that while FIG.2 illustrates block 212 as being performed prior to block 214, it is not a requirement and the two blocks 212, 214 may be processed in any order or in parallel and that FIG.2 is merely one example of process 204 for illustrative only. [0057] The UE may make a determination that a dedicated TCI state indication is correctly received if, for example, the pattern of criteria is met in the received DCI format. Subsequent to a positive determination that such a dedicated TCI state indication is received correctly, the UE may decode the TCI state(s) from the received DCI format, and apply the indicated TCI state(s) in the DCI format on PDCCH/PDSCH reception and/or PUSCH/PUCCH transmission. [0058] Another aspect relates to how the UE reports an acknowledgement of correct receipt of a dedicated TCI state indication to the gNB. Upon a positive determination by the UE that a dedicated TCI state indication is received correctly, the UE may report a HARQ-ACK information in response to the reception of such a DCI format. FIG.3 is a schematic flow diagram illustrating an exemplary process 300 of reporting an acknowledgement by the UE, in accordance with some embodiments. As shown in FIG.3, upon a positive determination of receipt of a TCI state indication at block 216, the UE at block 302 transmits an acknowledgement indicating that the TCI state indication is received correctly. [0059] In some embodiments, when the UE receives a DCI format 1_1 or 1_2 that is dedicated for TCI state indication and the UE decode it correctly, the UE can be requested to report HARQ-ACK to the gNB, which is used to notify the gNB that the UE receives the TCI state indication correctly. If a UE receives such a DCI format at slot n, the UE can determine the time location of the PUCCH resource for sending HARQ-ACK in response to this DCI by following one or more of the following methods: [0060] In one example, the UE can be requested to provide the HARQ-ACK in response to this DCI for TCI indication after N symbols from the last symbol of the PDCCH carrying the DCI format. The value of N can be pre-specified. The value of N can be configured by higher layer parameter. In another example, the DCI field “PDSCH-to-HARQ_feedback timing indicator” can be used to indicate an offset between the PDCCH carrying the DCI and the PUCCH for the UE to report HARQ-ACK. Identification of Dedicated DCI-Based TCI State Indication From DCI Format [0061] Some details examples are given below to illustrate how the UE determines if a received DCI format is a dedicated DCI-Based TCI State indication. [0062] In a first method, the UE can determine a DCI format 1_1 or 1_2 is a TCI state indication DCI format without DL PDSCH assignment if the following conditions are met: the CRC of a corresponding DCI format is scrambled with a CS-RNTI; and some of the DCI fields in the DCI format are set to some special values. [0063] The special values for the first method can be pre-specified. Some DCI fields in the DCI format 1_1 and 1_2 can be set according to one of more of the following examples.

This TCI-RNTI can be one RNTI that is dedicated for TCI indication functions; and Some of the DCI fields in the DCI format are set to some special values. [0066] Those special values for the second method can be pre-specified. Some DCI fields in the DCI format 1_1 and 1_2 can be set according one of more of the following examples.

This TCI-RNTI can be one RNTI that is dedicated for TCI indication functions; and some of the DCI fields in the DCI format are set to some special values. [0068] Those special values for the third method can be pre-specified. Some DCI fields in the DCI format 1_1 and 1_2 can be set according one of more of the following examples.

Acknowledgement of TCI Indication [0071] Some details examples are given below to illustrate how the UE reports an acknowledgement of correct receipt of a dedicated DCI-Based TCI State indication. [0072] When the UE receives a DCI format 1_1 or 1_2 that is dedicated for TCI state indication and the UE decode it correctly, the UE can be requested to report HARQ-ACK to the gNB, which is used to notify the gNB that the UE receives the TCI state indication correctly. If a UE receives such a DCI format at slot n, the UE can determine the time location of the PUCCH resource for sending HARQ-ACK in response to this DCI by following one or more of the following methods: [0073] In a first example, a UE reports HARQ-ACK information for a corresponding PDSCH reception or SPS PDSCH release or dedicated DCI-based TCI state indication only in a HARQ- ACK codebook that the UE transmits in a slot indicated by a value of a PDSCH-to- HARQ_feedback timing indicator field in a corresponding DCI format. The UE reports NACK value(s) for HARQ-ACK information bit(s) in a HARQ-ACK codebook that the UE transmits in a slot not indicated by a value of a PDSCH-to-HARQ_feedback timing indicator field in a corresponding DCI format. [0074] In a second example, a UE is expected to provide HARQ-ACK information in response to a dedicated DCI-based TCI state indication after N symbols from the last symbol of a PDCCH providing the dedicated DCI-based TCI state indication. If processingType2Enabled of PDSCH- ServingCellConfig is set to enable for the serving cell with the PDCCH a dedicated DCI-based TCI state indication, N=5 for μ=0, N=5.5 for μ=1, and N=11 for μ=2, otherwise, N=10 for μ=0, N=12 for μ=1, N=22 for μ=2, and N=25 for μ=3, wherein μ corresponds to the smallest SCS configuration between the SCS configuration of the PDCCH providing a dedicated DCI-based TCI state indication and the SCS configuration of a PUCCH carrying the HARQ-ACK information in response to a dedicated DCI-based TCI state indication. [0075] For DCI format 1_0, the PDSCH-to-HARQ_feedback timing indicator field values map to {1, 2, 3, 4, 5, 6, 7, 8}. For a DCI format, other than DCI format 1_0, scheduling a PDSCH reception or a SPS PDSCH release or dedicated TCI state indication, the PDSCH-to- HARQ_feedback timing indicator field values, if present, map to values for a set of number of slots provided by dl-DataToUL-ACK, dl-DataToUL-ACK-r16, or dl-DataToUL- ACKForDCIFormat1_2, as defined in Table 9.2.3-1. [0076] For a SPS PDSCH reception ending in slot , the UE transmits the PUCCH in slot n+k where k is provided by the PDSCH-to-HARQ_feedback timing indicator field, if present, in a DCI format activating the SPS PDSCH reception. [0077] If the UE detects a DCI format that does not include a PDSCH-to-HARQ_feedback timing indicator field and schedules a PDSCH reception or activates a SPS PDSCH reception ending in slot n, the UE provides corresponding HARQ-ACK information in a PUCCH transmission within slot n+k where k is provided by dl-DataToUL-ACK, or dl-DataToUL-ACK- r16, or dl-DataToUL-ACKForDCIFormat1_2. [0078] With reference to slots for PUCCH transmissions, if the UE detects a DCI format scheduling a PDSCH reception ending in slot n or if the UE detects a DCI format indicating a SPS PDSCH release or indicating a TCI state or indicating SCell dormancy through a PDCCH reception ending in slot n, or if the UE detects a DCI format that requests Type-3 HARQ-ACK codebook report and does not schedule a PDSCH reception through a PDCCH reception ending in slot n, as described in Clause 9.1.4, the UE provides corresponding HARQ-ACK information in a PUCCH transmission within slot n+k, where k is a number of slots and is indicated by the PDSCH-to-HARQ_feedback timing indicator field in the DCI format, if present, or provided by dl-DataToUL-ACK, dl-DataToUL-ACK-r16, or dl-DataToUL-ACKForDCIFormat1_2. k=0 corresponds to the last slot of the PUCCH transmission that overlaps with the PDSCH reception or with the PDCCH reception in case of SPS PDSCH release or in case of dedicated DCI-based TCI state indication or in case of SCell dormancy indication or in case of the DCI format that requests Type-3 HARQ-ACK codebook report and does not schedule a PDSCH reception. [0079] In one method, when the UE receives DCI format 1_1 or 1_2 without DL PDSCH assignment but with beam indication (which can be called dedicated DCI-based TCI state indication) according to the methods described above, the UE can be requested to report HARQ NACK or ACK corresponding to the reception of the DCI format. Upon a successful reception of the beam indication DCI format 1_1 or 1_2 without DL assignment, the UE can be requested to report a HARQ ACK corresponding to the reception of the DCI. The UE can be requested to determine the location of ACK bit in the HARQ-ACK codebook of Type-1 HARQ-ACK codebook according to one or more of the followings: [0080] For the Type-1 HARQ-ACK codebook, the UE can be requested to determine the location of the ACK bit in the HARQ-ACK codebook based on a first virtual PDSCH, where the time domain location of the first virtual PDSCH is indicated by the Time domain resource assignment DCI field in that DCI format 1_1 or 1_2 and the higher layer parameter pdsch- TimeDomainAllocationList or pdsch-TimeDomainAllocationListDCI-1-2. In other word, the parameters for the first virtual PDSCH: the value of k0, mapping type and startsymbolAndlength are indicated by the Time domain resource assignment DCI field in that DCI format 1_1 or 1_2 and the higher layer parameter pdsch-TimeDomainAllocationList or pdsch- TimeDomainAllocationListDCI-1-2. [0081] In a third example, for the Type-1 HARQ-ACK codebook, the UE can be requested to determine the location of the ACK bit in the HARQ-ACK codebook based on a second virtual PDSCH. The second virtual PDSCH time domain allocation is determined as follows: the slot location of the second virtual PDSCH is assumed to be in the same slot as the DCI format 1_1 or 1_2, in other word, the value of k0 is assumed to be 0. The parameters of mapping type and startsymbolAndlength of the second virtual PDSCH are according to the time resource allocation indicated by the Time domain resource assignment DCI field in that DCI format 1_1 or 1_2 and the higher layer parameter pdsch-TimeDomainAllocationList or pdsch- TimeDomainAllocationListDCI-1-2. [0082] In a fourth example, for the Type-1 HARQ-ACK codebook, the UE can be requested to determine the location of the ACK bit in the HARQ-ACK codebook based on a third virtual PDSCH. The third PDSCH time domain allocation is determined as follows: the value of k0 is indicated by the Time domain resource assignment DCI field in that DCI format 1_1 or 1_2 and the higher layer parameter pdsch-TimeDomainAllocationList or pdsch- TimeDomainAllocationListDCI-1-2. And The parameters of mapping type and startsymbolAndlength of the third virtual PDSCH are fixed and pre-specified to be one row of the higher layer parameter pdsch-TimeDomainAllocationList or pdsch- TimeDomainAllocationListDCI-1-2. The parameters of mapping type and startsymbolAndlength of the third virtual PDSCH are pre-specified to be the first row of the higher layer parameter pdsch-TimeDomainAllocationList or pdsch-TimeDomainAllocationListDCI-1-2. [0083] In a fifth example, for the Type-1 HARQ-ACK codebook, the UE can be requested to determine the location of the ACK bit in the HARQ-ACK codebook based on a fourth virtual PDSCH. The fourth PDSCH time domain allocation is determined as follows: the value of k0 the mapping type and startsymbolAndlength of the fourth virtual PDSCH are fixed and pre-specified to be one row of the higher layer parameter pdsch-TimeDomainAllocationList or pdsch- TimeDomainAllocationListDCI-1-2. The parameters of k0, mapping type and startsymbolAndlength of the fourth virtual PDSCH are pre-specified to be the first row of the higher layer parameter pdsch-TimeDomainAllocationList or pdsch- TimeDomainAllocationListDCI-1-2. [0084] In a sixth example, for the Type-1 HARQ-ACK codebook, the UE can be requested to determine the location of the ACK bit in the HARQ-ACK codebook based on a fifth virtual PDSCH. The fifth PDSCH time domain allocation is determined as follows: the value of k0 is fixed to a value and the parameters of the mapping type and startsymbolAndlength of the fourth virtual PDSCH are fixed and pre-specified to be one row of the higher layer parameter pdsch- TimeDomainAllocationList or pdsch-TimeDomainAllocationListDCI-1-2. The parameters of k0 is fixed to be 0 and the parameters of mapping type and startsymbolAndlength of the fifth virtual PDSCH are pre-specified to be the first row of the higher layer parameter pdsch- TimeDomainAllocationList or pdsch-TimeDomainAllocationListDCI-1-2. [0085] In a seventh example, the HARQ-ACK bit in Type1 HARQ codebook -ACK for dedicated DCI-based TCI state indication can be determined based on the following exemplary algorithm: For the set of slot timing values K ₁ , the UE determines a set of M _{A , c} occasions for candidate PDSCH receptions or SPS PDSCH releases or dedicated DCI-based TCI state indication according to the following pseudo-code. A location in the Type-1 HARQ-ACK codebook for HARQ-ACK information corresponding to a single SPS PDSCH release is same as for a corresponding SPS PDSCH reception. A location in the Type-1 HARQ-ACK codebook for HARQ-ACK information corresponding to multiple SPS PDSCH releases by a single DCI format is same as for a corresponding SPS PDSCH reception with the lowest SPS configuration index among the multiple SPS PDSCH releases. A location in the Type-1 HARQ-ACK codebook for a corresponding dedicated DCI-based TCI state indication is same as for the virtual PDSCH reception corresponding to the DCI format 1_1/1_2 of the dedicated DCI-based TCI state indication.

If a UE receives a SPS PDSCH, or a SPS PDSCH release, or dedicated DCI- based TCI state indication, or a PDSCH that is scheduled by a DCI format that does not support CBG-based PDSCH receptions and if - the UE is configured with one serving cell, and - C (M _A , _c ) = ¹ , and - PDSCH-CodeBlockGroupTransmission is provided to the UE the UE generates HARQ-ACK information only for the transport block in the PDSCH or only for the SPS PDSCH release or only for the dedicated DCI-based TCI state indication. If a UE receives a SPS PDSCH, or a SPS PDSCH release, or dedicated DCI- based TCI state indication or a PDSCH that is scheduled by a DCI format 1_0 and if - the UE is configured with more than one serving cells, or - C (M _A , _c ) > 1 , and - PDSCH-CodeBlockGroupTransmission is provided to the UE the UE repeats NCBG/TB, max H _{ARQ −ACK} times the HARQ-ACK information for the transport block in the PDSCH or for the SPS PDSCH release. A UE does not expect to detect a DCI format switching a DL BWP within N ₃ symbols prior to a first symbol of a PUCCH transmission where the UE multiplexes HARQ-ACK information, where N ₃ is defined in Clause 9.2.3. If a UE is provided dl-DataToUL-ACK or dl-DataToUL-ACK- ForDCIFormat1_2, the UE does not expect to be indicated by DCI format 1_0 a slot timing value for transmission of HARQ-ACK information that does not belong to the intersection of the set of slot timing values {1, 2, 3, 4, 5, 6, 7, 8} and the set of slot timing values provided by ^ _^ for the active DL BWP of a corresponding serving cell. If maxNrofCodeWordsScheduledByDCI indicates reception of two transport blocks, when the UE receives a PDSCH with one transport block or a SPS PDSCH release or dedicated DCI-based TCI state indication, the HARQ-ACK information is associated with the first transport block and the UE generates a NACK for the second transport block if harq-ACK-SpatialBundlingPUCCH is not provided and generates HARQ-ACK information with value of ACK for the second transport block if harq- ACK-SpatialBundlingPUCCH is provided. A UE determines HARQ-ACK information bits, for a total number of O _ACK HARQ-ACK information bits, of a HARQ-ACK codebook for transmission in a PUCCH according to the following pseudo-code. In the following pseudo-code, if the UE does not receive a transport block or a CBG, due to the UE not detecting a corresponding DCI format, the UE generates a NACK value for the transport block or the CBG. The cardinality of the set ^M _{A , c} defines a total number _{M c} of occasions for PDSCH reception or SPS PDSCH release or dedicated DCI-based TCI state indication for serving cell c corresponding to the HARQ-ACK information bits.

[0086] In one method, for the Type-2 HARQ-ACK codebook, the UE can be requested to determine the location of the ACK bit in the HARQ-ACK codebook for the dedicated DCI-based TCI state indication according the DAI value indicated in the DCI format 1_1 or 1_2. In one example, the HARQ-ACK bit for dedicated DCI-based TCI state indication in Type2 HARQ codebook -ACK can be determined based on the exemplary algorithm below: A UE determines monitoring occasions for PDCCH with DCI format scheduling PDSCH receptions or SPS PDSCH release or indicating SCell dormancy or dedicated DCI-based TCI state indication on an active DL BWP of a serving cell J, as described in Clause 10.1, and for which the UE transmits HARQ-ACK information in a same PUCCH in slot ^ based on - PDSCH-to-HARQ_feedback timing indicator field values for PUCCH transmission with HARQ-ACK information in slot ^ in response to PDSCH receptions, SPS PDSCH release or SCell dormancy indication or dedicated DCI-based TCI state indication. - slot offsets ^ _K [6, TS 38.214] provided by time domain resource assignment field in a DCI format scheduling PDSCH receptions and by pdsch- AggregationFactor, or pdsch-AggregationFactor-r16, or repetitionNumber, when provided. The set of PDCCH monitoring occasions for a DCI format scheduling PDSCH receptions or SPS PDSCH release or indicating SCell dormancy or a dedicated DCI- based TCI state indication is defined as the union of PDCCH monitoring occasions across active DL BWPs of configured serving cells. PDCCH monitoring occasions are indexed in an ascending order of start time of the search space sets associated with a PDCCH monitoring occasion. The cardinality of the set of PDCCH monitoring occasions defines a total number L of PDCCH monitoring occasions. A value of the counter downlink assignment indicator (DAI) field in DCI formats denotes the accumulative number of {serving cell, PDCCH monitoring occasion}-pair(s) in which PDSCH reception(s), SPS PDSCH release or SCell dormancy indication or dedicated DCI-based TCI state indication associated with the DCI formats is present up to the current serving cell and current PDCCH monitoring occasion, - first, if the UE indicates by type2-HARQ-ACK-Codebook support for more than one PDSCH reception on a serving cell that are scheduled from a same PDCCH monitoring occasion, in increasing order of the PDSCH reception starting time for the same {serving cell, PDCCH monitoring occasion} pair, - second in ascending order of serving cell index, and - third in ascending order of PDCCH monitoring occasion index M, where 0 ≤ M < L. If, for an active DL BWP of a serving cell, the UE is not provided coresetPoolIndex or is provided coresetPoolIndex with value 0 for one or more first CORESETs and is provided coresetPoolIndex with value 1 for one or more second CORESETs, and is provided ackNackFeedbackMode = joint, the value of the counter DAI is in the order of the first CORESETs and then the second CORESETs for a same serving cell index and a same PDCCH monitoring occasion index. The value of the total DAI, when present [5, TS 38.212], in a DCI format denotes the total number of {serving cell, PDCCH monitoring occasion}-pair(s) in which PDSCH reception(s), SPS PDSCH release or SCell dormancy indication or dedicated DCI-based TCI state indication associated with DCI formats is present, up to the current PDCCH monitoring occasion M and is updated from PDCCH monitoring occasion to PDCCH monitoring occasion.

Denote by the number of bits for the counter DAI and set Denote by the value of the counter DAI in a DCI format scheduling PDSCH reception, SPS PDSCH release or SCell dormancy indication or dedicated DCI-based TCI state indication on serving cell J in PDCCH monitoring occasion M according to Table 9.1.3-1 or Table 9.1.3-1A. Denote by the value of the total DAI in a DCI format in PDCCH monitoring occasion M according to Table 9.1.3-1. The UE assumes a same value of total DAI in all DCI formats that include a total DAI field in PDCCH monitoring occasion M. A UE does not expect to multiplex, in a same Type-2 HARQ- ACK codebook, HARQ-ACK information that is in response to detection of DCI formats with different number of bits for the counter DAI field. If the UE transmits HARQ-ACK information in a PUCCH in slot ^ and for any PUCCH format, the UE determines the , for a total number of information bits, according to the following pseudo-code: Set M = 0 – PDCCH with DCI format scheduling PDSCH reception, SPS PDSCH release or dedicated DCI-based TCI state indication or SCell dormancy indication monitoring occasion index: lower index corresponds to earlier PDCCH monitoring occasion Set a = 0 Set S _EBFC = 0 Set S _EBFC1 = 0 Set Set to the number of serving cells configured by higher layers for the UE - if, for an active DL BWP of a serving cell, the UE is not provided coresetPoolIndex or is provided coresetPoolIndex with value 0 for one or more first CORESETs and is provided coresetPoolIndex with value 1 for one or more second CORESETs, and is provided ACKNackFeedbackMode = JointFeedback, the serving cell is counted two times where the first time corresponds to the first CORESETs and the second time corresponds to the second CORESETs - if the UE indicates type2-HARQ-ACK-Codebook, a serving cell is counted times where is the number of PDSCH receptions that can be scheduled for the serving cell by DCI formats in PDCCH receptions at a same PDCCH monitoring occasion based on the reported value of type2-HARQ-ACK-Codebook Set L to the number of PDCCH monitoring occasion(s) while M < L Set J = 0 – serving cell index: lower indexes correspond to lower RRC indexes of corresponding cell while if PDCCH monitoring occasion M is before an active DL BWP change on serving cell J or an active UL BWP change on the PCell and an active DL BWP change is not triggered in PDCCH monitoring occasion M J = J + 1; else if there is a PDSCH on serving cell J associated with PDCCH in PDCCH monitoring occasion M, or there is a PDCCH indicating SPS PDSCH release or SCell dormancy or dedicated DCI-based TCI state indication on serving cell J if j = j + 1

If a UE is configured to receive SPS PDSCH and the UE multiplexes HARQ- ACK information for multiple activated SPS PDSCH receptions in the PUCCH in slot ^, the UE generates the HARQ-ACK information as described in Clause 9.1.2 and appends it to the HARQ-ACK information bits. For a PDCCH monitoring occasion with DCI format scheduling PDSCH reception or SPS PDSCH release or indicating SCell dormancy in the active DL BWP of a serving cell, when a UE receives a PDSCH with one transport block or a SPS PDSCH release or indicating SCell dormancy or dedicated DCI-based TCI state indication and the value of maxNrofCodeWordsScheduledByDCI is 2, the HARQ-ACK information is associated with the first transport block and the UE generates a NACK for the second transport block if harq-ACK-SpatialBundlingPUCCH is not provided and generates HARQ-ACK information with value of ACK for the second transport block if harq- ACK-SpatialBundlingPUCCH is provided.
