CROSS-REFERENCE TO RELATED APPLICATION

[0001] This Patent Application claims priority to U.S. Nonprovisional Patent Application No. 17/648,860, filed on January 25, 2022, entitled “APPLYING A UNIFIED TRANSMISSION CONFIGURATION INDICATOR STATE INDICATION TO CHANNELS OR SIGNALS ASSOCIATED WITH A CONTROL RESOURCE SET POOL INDEX VALUE,” which is hereby expressly incorporated by reference herein.

FIELD OF THE DISCLOSURE

[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for applying a unified transmission configuration indicator (TCI) state indication to channels or signals associated with a control resource set (CORESET) pool index value.

BACKGROUND

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC- FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3 GPP).

[0004] A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station. [0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple -output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

DETAILED DESCRIPTION

[0027] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. [0028] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. [0029] While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

[0030] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more base stations 110 (shown as a BS 110a, a BS 110b, a BS 110c, and a BS 1 lOd), a user equipment (UE) 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and/or other network entities. A base station 110 is an entity that communicates with UEs 120. A base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station 110 and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

[0031] A base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in Fig. 1, the BS 110a may be a macro base station for a macro cell 102a, the BS 110b may be a pico base station for a pico cell 102b, and the BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

[0032] In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station 110 that is mobile (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected to one another and/or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

[0033] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station 110 or a UE 120) and send a transmission of the data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in Fig. 1, the BS 1 lOd (e.g., a relay base station) may communicate with the BS 110a (e.g., a macro base station) and the UE 120d in order to facilitate communication between the BS 110a and the UE 120d. A base station 110 that relays communications may be referred to as a relay station, a relay base station, a relay, or the like.

[0034] The wireless network 100 may be a heterogeneous network that includes base stations 110 of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network 100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0. 1 to 2 watts).

[0035] A network controller 130 may couple to or communicate with a set of base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via a backhaul communication link. The base stations 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

[0036] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium.

[0037] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Intemet-of-Things (loT) devices, and/or may be implemented as NB-IoT (narrowband loT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

[0038] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0039] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to- vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

[0040] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

[0041] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz).

Each of these higher frequency bands falls within the EHF band.

[0042] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

[0043] In some aspects, a UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive, from a base station, downlink control information (DCI) that includes a unified transmission configuration indicator (TCI) state indication to be applied for a channel or a signal associated with a control resource set (CORESET) pool index value in a component carrier (CC), wherein the CC is configured as part of a list for simultaneous unified TCI state indication across multiple CCs; and apply the unified TCI state indication to the channel or the signal associated with the CORESET pool index value in one or more CCs indicated in the list. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0044] In some aspects, a base station (e.g., base station 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit, to a UE, DCI that includes a unified TCI state indication to be applied for a channel or a signal associated with a CORESET pool index value in a CC, wherein the CC is configured as part of a list for simultaneous unified TCI state indication across multiple CCs; and communicate the channel or the signal associated with the CORESET pool index value based at least in part on the unified TCI state indication applied to the channel or the signal associated with the CORESET pool index value in one or more CCs indicated in the list. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0045] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

[0046] Fig. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The base station 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T> 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1).

[0047] At the base station 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple -output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, fdter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), shown as antennas 234a through 234t.

[0048] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the base station 110 and/or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., fdter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0049] The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0050] One or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2.

[0051] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RS SI, RSRQ, and/or CQI) from the controller/processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and/or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller/processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 7-12). [0052] At the base station 110, the uplink signals from UE 120 and/or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 232), detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller/processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of the antenna(s) 234, the modem(s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and/or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller/processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 7-12).

[0053] The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of Fig. 2 may perform one or more techniques associated with applying a unified TCI state indication to channels or signals associated with a CORESET pool index value, as described in more detail elsewhere herein. For example, the controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of Fig. 2 may perform or direct operations of, for example, process 900 of Fig. 9, process 1000 of Fig. 10, and/or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some examples, the memory 242 and/or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 900 of Fig. 9, process 1000 of Fig. 10, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

[0054] In some aspects, a UE (e.g., UE 120) includes means for receiving, from a base station, DCI that includes a unified TCI state indication to be applied for a channel or a signal associated with a CORESET pool index value in a CC, wherein the CC is configured as part of a list for simultaneous unified TCI state indication across multiple CCs; and/or means for applying the unified TCI state indication to the channel or the signal associated with the CORESET pool index value in one or more CCs indicated in the list. The means for the UE to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

[0055] In some aspects, a base station (e.g., base station 110) includes means for transmitting, to a UE, DCI that includes a unified TCI state indication to be applied for a channel or a signal associated with a CORESET pool index value in a CC, wherein the CC is configured as part of a list for simultaneous unified TCI state indication across multiple CCs; and/or means for communicating the channel or the signal associated with the CORESET pool index value based at least in part on the unified TCI state indication applied to the channel or the signal associated with the CORESET pool index value in one or more CCs indicated in the list. The means for the base station to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller/processor 240, memory 242, or scheduler 246.

[0056] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of the controller/processor 280. [0057] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2. [0058] Fig. 3 is a diagram illustrating an example 300 of multi -downlink control information (multi -DCI) based multi -TRP (mTRP) transmissions, in accordance with the present disclosure. [0059] As shown by reference number 302, for multi -DCI-based mTRP transmissions, a first TRP may transmit a first DCI via a first physical downlink control channel (PDCCH). The first DCI may schedule a first physical downlink shared channel (PDSCH), a first physical uplink control channel (PUCCH), and/or a first physical uplink shared channel (PUSCH), which may be transmitted from or to the first TRP. A second TRP may transmit a second DCI via a second PDCCH. The second DCI may schedule a second PDSCH, a second PUCCH, and/or a second PUSCH, which may be transmitted from or to the second TRP.

[0060] A TRP differentiation at a UE may be based at least in part on a CORESET pool index (CORESETPoolIndex). Each CORESET (e.g., with a maximum of 5 CORESETs) may be configured with a CORESETPoolIndex value. The CORESETPoolIndex value may be 0 or 1, which may group CORESETs into two groups. Other than the CORESETPoolIndex value, different TRPs may be transparent to the UE. The UE may be configured with multi-DCI -based mTRP when the UE is configured by a higher layer parameter PDCCH-Config that contains two different values of CORESETPoolIndex in CORESETs for an active bandwidth part (BWP) of a serving cell. Further, an mTRP operation may be defined in a given component carrier (CC) by configuring two CORESETPoolIndex values in different CORESETs in the active BWP of that CC. When a CORESET is not configured with a CORESETPoolIndex value, a CORESETPoolIndex value of zero may be assumed.

[0061] As shown by reference number 304, a first CORESETPoolIndex (e.g., CORESETPoolIndex = 0) may be associated with a first CORESET identifier (ID) (e.g., CORESET ID=1) and a second CORESET ID (e.g., CORESET ID=2). A second CORESETPoolIndex (e.g., CORESETPoolIndex = 1) may be associated with a third CORESET ID (e.g., CORESET ID=3) and a fourth CORESET ID (e.g., CORESET ID=4).

[0062] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.

[0063] A scheduling DCI may dynamically schedule channels and/or signals, which may be associated with a CORESETPoolIndex value based at least in part on a CORESET configuration of the scheduling DCI. The channels and/or signals may include a PDSCH scheduled by a DCI (e.g., DCI formats 1 0, 1 1, 1 2), a hybrid automatic repeat request acknowledgement (HARQ- ACK) transmitted on a PUCCH for a PDSCH that is scheduled by a DCI (e.g., DCI formats 1 0, 1 1, 1 2), and/or a PUSCH scheduled by a DCI (e.g., DCI formats 0 0, 0 1, 0 2). Other channels and/or signals which may not be associated with a CORESETPoolIndex value may include a semi-persistent scheduling (SPS) PDSCH, a HARQ-ACK transmitted on a PUCCH for an SPS PDSCH, a channel state information (CSI) report transmitted on a PUCCH for an SPS PDSCH, a scheduling request (SR) transmission on a PUCCH, and/or a configured grant PUSCH (CG-PUSCH) associated with a Type 1 or a Type 2.

[0064] For a beam indication, a transmission configuration indicator (TCI) state may be defined for downlink signals/channels. A radio resource control (RRC) configuration may configure up to 128 TCI states. For a PDCCH, one TCI state may be activated by a medium access control control element (MAC-CE) per CORESET. For a channel state information reference signal (CSI-RS), a TCI state may be configured via RRC signaling (e.g., for a periodic CSI-RS or an aperiodic CSI-RS) or may be indicated by a MAC-CE (e.g., for a semi-persistent CSI-RS (SP-CSI-RS))

[0065] For a PDSCH, up to 8 TCI states may be activated by a MAC-CE and mapped to 8 TCI codepoints in DCI (DCI formats 1_1/1_2). DCI may indicate one of the activated TCI states via a TCI field, where an indication by the DCI may be for a scheduled PDSCH and may not be applicable to other PDSCHs. When two CORESETPoolIndex values are configured for a CC, separate MAC-CEs may activate up to 8 TCI states per CORESETPoolIndex. A TCI field of a DCI format 1_1/1_2 may be interpreted differently (based at least in part on a corresponding MAC-CE) depending on whether the TCI field is received on a CORESET with a CORESETPoolIndex value of 0 or 1.

[0066] For an uplink, spatial relation information may be used for a definition of an uplink beam, where the spatial relation information may be used instead of a TCI state. For a PUCCH, one spatial relation information may be activated by a MAC-CE per PUCCH resource. For a PUSCH, a sounding reference signal (SRS) resource indicator (SRI) field in a scheduling DCI may point to one or more SRS resources (e.g., within a configured SRS resource set for a codebook- or non-codebook-based uplink), and spatial relation information associated with the indicated SRS resource(s) may be used for the scheduled PUSCH. For an SRS, spatial relation information may be configured via RRC signaling (e.g., for a periodic SRS) or may be indicated by a MAC-CE (e.g., for a semi-persistent SRS or an aperiodic SRS) per SRS resource.

[0067] Fig. 4 is a diagram illustrating an example 400 of TCI states activation or deactivation, in accordance with the present disclosure.

[0068] As shown in Fig. 4, TCI states activation/deactivation may be defined for a UE- specific PDSCH MAC-CE. The UE-specific PDSCH MAC-CE may activate up to 8 TCI states, which may be mapped to 8 TCI codepoints. The UE-specific PDSCH MAC-CE may be associated with a CORESETPoolIndex, a serving cell ID, and a BWP ID.

[0069] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.

[0070] With a unified DCI, downlink TCI states, uplink TCI states, or joint downlink/uplink TCI states may be RRC-configured. A MAC-CE may activate a quantity of RRC-configured TCI states, and may map to TCI field codepoints with various possibilities. One TCI field codepoint may represent a joint downlink/uplink TCI state mapped to one TCI codepoint, which may be used for a joint downlink/uplink beam indication. One TCI field codepoint may represent a paired downlink TCI state and uplink TCI state, which may be used for separate downlink/uplink beam indication. One TCI field codepoint may represent only a downlink TCI state, which may be used for only downlink beam indication. One TCI field codepoint may represent only an uplink TCI state, which may be used for only uplink beam indication.

[0071] When a MAC-CE indicates a mapping to only a single TCI field codepoint, the single TCI field codepoint may serve as a beam indication. The beam indication may be applied, for example, 3 ms after a HARQ-ACK to a PDSCH carrying the MAC-CE. When a MAC-CE indicates a mapping to more than one TCI field codepoint, downlink DCI (e.g., DCI format 1 1/1 2) with or without a downlink assignment may indicate a beam through a TCI field codepoint. In this case, a beam indication may be applied in a first slot that is at least Y symbols (e.g., which may be RRC -configured based at least in part on a UE capability) after a last symbol of a PUCCH carrying a HARQ-ACK in response to the downlink DCI.

[0072] With the unified TCI, a beam indication may be “sticky”, such that the beam indication is not related to a scheduled PDSCH and may not be a one-time indication. When the beam indication is applied, the beam indication may remain the same for applicable channels/signals until another DCI format 1_1/1_2 changes the beam. The beam indication may be for uplink or for both downlink and uplink, even though the beam indication may be transmitted in DCI formats 1_1/1_2. The beam indication may be common for multiple downlink channels/signals (e.g., PDSCH, PDCCH, and/or CSI-RS) and/or multiple uplink channels/signals (e.g., PUSCH, PUCCH, and/or SRS). Further, the beam indication may be defined for a single TRP (sTRP).

[0073] Fig. 5 is a diagram illustrating an example 500 of a unified TCI, in accordance with the present disclosure.

[0074] As shown in Fig. 5, a base station may transmit a DCI (e.g., a DCI format 1_1/1_2) with a beam indication to a UE. The base station may transmit the DCI with or without a PDSCH scheduling. The base station may provide the beam indication using a TCI field codepoint. The base station may receive, from the UE and based at least in part on the DCI transmission, a PUCCH with a HARQ-ACK. At Y symbols after the HARQ-ACK transmission, the beam indication may be applied to downlink channels/signals, uplink channels/signals, or to both downlink/uplink channels/signals, depending on a type associated with the TCI field codepoint.

[0075] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5. [0076] A simultaneous TCI state activation/indication may be used for multiple CCs. Two lists may be configured using RRC signaling via a simultaneousTCI-UpdateListl parameter and a simultaneousTCI-UpdateList2 parameter. When an indicated serving cell in a MAC-CE (e.g., a “Serving Cell ID” field in a MAC-CE) is configured as part of the first list or the second list, the MAC CE may apply to a plurality of serving cells (e.g., all serving cells) in the first list or in the second list. The two lists may be configured for a PDSCH TCI state activation MAC-CE, a PDCCH TCI state activation MAC-CE, or an SRS spatial relation indication MAC-CE.

[0077] With a unified TCI, when a DCI (e.g., DCI format 1_1/1_2 with or without a scheduled PDSCH) indicates a TCI state to be applied to multiple downlink/uplink signals/channels for a CC, and when the CC is configured as part of a first list or a second list, the indicated TCI codepoint may be applied to a plurality of CCs (e.g., all CCs) in the first list or in the second list. When multiple CCs in the first list or in the second list have different subcarrier spacings (SCSs), a time for applying an indicated beam may be a first slot after Y symbols after a PUCCH carrying a HARQ-ACK, where the first slot and the Y symbols may be based at least in part on a CC with a smallest SCS among CC(s) applying the indicated beam. [0078] Fig. 6 is a diagram illustrating an example 600 of a TCI state indication, in accordance with the present disclosure.

[0079] As shown in Fig. 6, a TCI state indication may be defined for a UE-specific PDCCH MAC-CE. The UE-specific PDCCH MAC-CE may be associated with a serving cell ID, a CORESET ID, and a TCI state ID. When the serving cell ID indicated in the UE-specific PDCCH MAC-CE is configured as part of a first list or a second list, the UE-specific PDCCH MAC-CE may apply to a plurality of serving cells (e.g., all serving cells) in the first list or in the second list.

[0080] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with regard to Fig. 6.

[0081] A UE may support a unified TCI in a multi -DCI-based mTRP. However, the UE may not be configured to handle a unified TCI with simultaneous TCI state indication for multiple CCs for the multi-DCI-based mTRP when two different values of CORESET pool index values in CORESETs are configured for a CC.

[0082] In various aspects of techniques and apparatuses described herein, a UE may receive, from a base station, DCI that includes a unified TCI state indication to be applied for a channel or a signal associated with a CORESET pool index value in a CC. The CC may be configured as part of a list for simultaneous unified TCI state indication across multiple CCs. The UE may apply the unified TCI state indication to the channel or the signal associated with the CORESET pool index value in one or more CCs indicated in the list. [0083] In some aspects, the unified TCI may be extended to the multi-DCI-based mTRP. The unified TCI may provide the simultaneous TCI state indication for multiple CCs. The unified TCI, which may include a DCI-based beam indication for multiple downlink/uplink signals/channels, may be extended to the case of multi-DCI-based mTRP when two different values of a CORESETPoolIndex in CORESETs are configured for a CC or for an active BWP of the CC. Some CCs on a list (e.g., a first list or a second list) may not be configured with a CORESETPoolIndex value, or may be configured with one value of CORESETPoolIndex. In this case, certain CCs on the list may be considered when a TCI state is indicated and applied for downlink/uplink channels/signals associated with a given CORESETPoolIndex value.

[0084] Fig. 7 is a diagram illustrating an example 700 associated with applying a unified TCI state indication to channels or signals associated with a CORESET pool index value, in accordance with the present disclosure. As shown in Fig. 7, example 700 includes communication between a UE (e.g., UE 120) and a base station (e.g., base station 110). In some aspects, the UE and the base station may be included in a wireless network, such as wireless network 100.

[0085] As shown by reference number 702, the UE may receive (e.g., using antenna 252, modem 254, MIMO detector 256, receive processor 258, controller/processor 280, and/or memory 282), from the base station, DCI that includes a unified TCI state indication to be applied for a channel or a signal associated with a CORESET pool index value in a CC. The CC may be configured as part of a list for simultaneous unified TCI state indication across multiple CCs. The DCI may be a DCI format with or without a scheduling PDSCH. The unified TCI state indication may be associated with a downlink state, an uplink state, or a joint TCI state. The channel may correspond to a downlink channel or an uplink channel. The signal may correspond to a downlink signal or an uplink signal.

[0086] As shown by reference number 704, the UE may apply (e.g., using communication manager 140 and/or controller/processor 280) the unified TCI state indication to the channel or the signal associated with the CORESET pool index value in one or more CCs indicated in the list. The one or more CCs indicated in the list may correspond to a plurality of CCs (e.g., all CCs) indicated in the list. The UE may apply the unified TCI state indication to the uplink channel, the downlink channel, the uplink signal, and/or the downlink signal associated with the CORESET pool index value in the one or more CCs indicated in the list.

[0087] In some aspects, when a DCI (e.g., DCI format 1_1/1_2) with or without scheduling a PDSCH indicates a unified TCI state (e.g., a downlink/uplink/joint TCI state) to be applied for downlink/uplink channels/signals associated with a given CORESETPoolIndex value in a CC, and when the CC is configured as part of a list (e.g., a first list or a second list) for a simultaneous TCI state indication across multiple CCs, a TCI state indication (or unified TCI state indication) may also be applied to downlink/uplink channels/signals associated with that CORESETPoolIndex value in a plurality of CCs (e.g., all CCs) in that list.

[0088] In some aspects, a quantity of CCs indicated in the list may not be associated with a CORESET pool index value. The UE may apply the unified TCI state indication to the quantity of CCs indicated in the list based at least in part on a CORESET pool index value associated with the DCI being zero. Alternatively, the UE may not apply (or may refrain from applying) the unified TCI state indication to the quantity of CCs indicated in the list.

[0089] In some aspects, one or more CCs in the list may not be configured with a CORESETPoolIndex value (e.g., either CORESETPoolIndex value 0 or CORESETPoolIndex value 1), such that the one or more CCs may not be configured with multi -DCI-based mTRP. In some aspects, when the one or more CCs in the list are not configured with the CORESETPoolIndex value, the TCI state indication may be applied to the one or more CCs only when a CORESETPoolIndex value associated with the DCI is value 0. Downlink/uplink signals/channels without a CORESETPoolIndex value in a CC not configured with a CORESETPoolIndex value may be assumed to be associated with CORESETPoolIndex value 0. In some aspects, when the one or more CCs in the list are not configured with the CORESETPoolIndex value, the TCI state indication may not be applied to the one or more CCs. [0090] In some aspects, a quantity of CCs indicated in the list may be associated with a single CORESET pool index value. The UE may apply the unified TCI state indication to the quantity of CCs indicated in the list based at least in part on the CORESET pool index value associated with the DCI corresponding to the single CORESET pool index value. Alternatively, the UE may not apply (or may refrain from applying) the unified TCI state indication to the quantity of CCs indicated in the list based at least in part on the CORESET pool index value associated with the DCI being different than the single CORESET pool index value.

[0091] In some aspects, when one or more CCs in the list are associated with only one CORESETPoolIndex value (e.g., either CORESETPoolIndex value 0 or CORESETPoolIndex value 1), the TCI state indication may be applied to the one or more CCs only when a CORESETPoolIndex value associated with the DCI is the same as the only one CORESETPoolIndex value. In this case, a beam indication for the one or more CCs may not be applied when the only one CORESETPoolIndex value is different than the CORESETPoolIndex value associated with the DCI.

[0092] In some aspects, the UE may apply the unified TCI state indication at a first slot that occurs a quantity of symbols after a PUCCH carrying feedback associated with the DCI. The first slot and the quantity of symbols may be based at least in part on a CC with a smallest SCS among CCs of the multiple CCs for which the unified TCI state indication is applied. Alternatively, the first slot and the quantity of symbols may be based at least in part on a CC with a smallest SCS among the multiple CCs indicated in the list.

[0093] In some aspects, a time of applying an indicated TCI state may be a first slot after Y symbols after a PUCCH carrying a HARQ-ACK. In some aspects, the first slot and Y symbols may be based at least in part on a CC with a smallest SCS among CC(s) for which the TCI state indication is applied. When a CC is configured as part of a list (e.g., a same list as a CC associated with a beam indication DCI), but the beam indication DCI is not applied to that CC (e.g., due to not having downlink/uplink channels/signals associated with a CORESETPoolIndex value of the beam indication DCI), that CC may not be considered when determining the smallest SCS. As a result, a timeline for applying the indicated TCI state may not be a function of the SCS of that CC.

[0094] In some aspects, the first slot and Y symbols may be based at least in part on a CC with a smallest SCS among CC(s) that belong to the same list as the CC associated with the beam indication DCI. When the CC is configured as part of the list, even when the beam indication DCI is not applied to that CC (e.g., due to not having downlink/uplink channels/signals associated with a CORESETPoolIndex value of the beam indication DCI), that CC may be considered when determining the smallest SCS. As a result, a timeline for applying the indicated TCI state may be a function of the SCS of that CC.

[0095] As an example, the base station may configure a first list and a second list, where the first list may indicate CCs of { 1, 2, 4, 6, 7} and the second list may indicate CCs of {3, 5, 8} . Further, CC4 and CC6 may be configured with two values of CORESETPoolIndex values, CC1 may not be configured with a CORESETPoolIndex value, CC2 may only be associated with CORESETPoolIndex value 1, and CC7 may only be associated with CORESETPoolIndex value 0. In a first scenario, CC2, CC4, and CC6 may be considered for determination of a smallest SCS, and thus a determination of a first slot and Y symbols, based at least in part on a beam indication DCI not being applied to certain CCs configured as part of a CC list. In a second scenario, CC1, CC2, CC4, CC6, and CC7 may be considered for determination of a smallest SCS, and thus a determination of a first slot and Y symbols, based at least in part on CCs that are configured as part of a CC list irrespective of whether a beam indication DCI is applied to certain CCs on the CC list.

[0096] As indicated above, Fig. 7 is provided as an example. Other examples may differ from what is described with regard to Fig. 7.

[0097] Fig. 8 is a diagram illustrating an example 800 associated with applying a unified TCI state indication to channels or signals associated with a CORESET pool index value, in accordance with the present disclosure. As shown in Fig. 8, example 800 includes communication between a UE (e.g., UE 120) and a base station (e.g., base station 110). In some aspects, the UE and the base station may be included in a wireless network, such as wireless network 100.

[0098] As shown in Fig. 8, a base station may transmit, to a UE, DCI (e.g., DCI format 1 1/1 2) with a beam indication, and with or without a PDSCH scheduling. The DCI may indicate, via a TCI field codepoint, a TCI state 1 for a CORESETPoolIndex value 1. The base station may transmit the DCI using a fourth CC (CC4). In this example, the beam indication may be for CC4 and CORESETPoolIndex value 1.

[0099] In some aspects, the base station may configure a first list and a second list, where the first list may indicate CCs of { 1, 2, 4, 6, 7} and the second list may indicate CCs of {3, 5, 8} . In other words, the first list may be associated with CC1, CC2, CC4, CC6, and CC7, and the second list may be associated with CC3, CC5, and CC8. In this example, CC4 and CC6 may be configured with two values of CORESETPoolIndex values, CC1 may not be configured with a CORESETPoolIndex value, CC2 may only be associated with CORESETPoolIndex value 1, and CC7 may only be associated with CORESETPoolIndex value 0.

[0100] In some aspects, since the DCI with the beam indication is transmitted on CC4, which is associated with the first list, the beam indication may initially be associated with all of the CCs associated with the first list. However, since CC1 is not configured with a CORESETPoolIndex value and CC7 is only associated with a CORESETPoolIndex value 0, the beam indication may not be associated with CC1 and CC7. Thus, the beam indication may be applied to CC4, CC6, and CC2. In other words, TCI state 1 may be applied to downlink/uplink signals/channels associated with CORESETPoolIndex value 1 in CC4, CC6, and CC2.

[0101] As indicated above, Fig. 8 is provided as an example. Other examples may differ from what is described with regard to Fig. 8.

[0102] Fig. 9 is a diagram illustrating an example process 900 performed, for example, by a UE, in accordance with the present disclosure.
