Description

[Technical Field]

[0001] The following relates to wireless communications, including channel state information (CSI) reporting using single and joint transmission reception point (TRP) measurements. [Background technology]

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasts, and so on. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE), LTE-Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communication system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, sometimes known as user equipment (UE). Summary of the Invention

[0003] The described techniques relate to improved methods, systems, devices, and apparatuses that support channel state information (CSI) reporting using single and joint transmit / receive point (TRP) measurements. Generally, the described techniques provide for a user equipment (UE) to transmit CSI reports related to both single and joint TRP measurements. For example, the UE may receive control signaling indicating one or more CMR pairs, including a first subset of CMRs from a set of channel measurement resources (CMRs) for single TRP measurements associated with a first TRP and a second subset of CMRs from a second set of CMRs for single TRP measurements associated with a second TRP. Here, each CMR pair may include one CMR from the first subset (e.g., associated with the first TRP) and one CMR from the second subset (e.g., associated with the second TRP). The UE may then monitor the indicated CMRs (e.g., the first subset, the second subset, and one or more CMR pairs) to generate a set of measurements for the CSI. The UE may transmit a CSI report indicating one or more channel resource indicators associated with at least one of the sets of measurements. In some cases, the UE may indicate one or more channel resource indicators within a number of bits based on the number of CMR pairs indicated by the control signaling. That is, a code space associated with a number of bits (e.g., the number of possible CMRs indicated by each channel resource indicator) may be based on the number of CMR pairs, and therefore the number of bits indicating the channel resource indicator may also be based on the number of CMR pairs.

[0004] In another example, the described technique provides for a UE to transmit CSI reports associated with both single-TRP measurements and joint-TRP measurements, where the UE shares a precoding matrix indicator (PMI) and a rank indicator (RI) between CSI measurements associated with both the single-TRP measurements and the joint-TRP measurements. For example, the UE may receive control signaling indicating a pair of CMRs and that first and second PMIs and first and second RIs calculated for channel measurements associated with the CMR pair can be shared to individually generate channel measurements (e.g., channel quality indicators (CQIs)) for each CMR in the CMR pair. The UE may monitor the pair of CMRs to generate joint-TRP CSI (e.g., including the first and second PMIs and the first and second RIs). The UE may further generate a first single TRP CSI associated with the first TRP including the first PMI and the first RI and a second single TRP CSI associated with the second TRP including the second PMI and the second RI. The UE may then transmit a CSI report including CQI associated with both the joint TRP and the single TRP generated using the shared PMI, the shared RI, or both.

[0005] A method for wireless communication in a UE is described. The method may include receiving control signaling indicating a first subset of CMRs in a first CMR group for single-TRP channel measurement associated with a first TRP for joint TRP channel measurement, a second subset of CMRs in a second CMR group for single-TRP channel measurement associated with a second TRP, and one or more CMR pairs including CMRs from each of the first CMR group and the second CMR group, monitoring the first subset of CMRs, the second subset of CMRs, and the one or more CMR pairs to generate a set of multiple measurements, and transmitting a CSI report including a number of bits indicating one or more CRIs associated with at least one of the sets of multiple measurements, where the number of bits is based on a number of CMR pairs.

DETAILED DESCRIPTION OF THE INVENTION

[0046]

[0061] In some wireless communication systems, a base station may transmit one or more channel state information reference signals (CSI-RS) to a user equipment (UE). The UE may measure one or more channel measurement resources (CMRs) (e.g., associated with the CSI-RSs) to generate a CSI report for transmission to the base station. For example, the UE may indicate to the base station within the CSI report one or more resources associated with better measurement quality (e.g., compared to other resources associated with the CMRs) for future communication between the base station and the UE. In some cases, a base station may be associated with two or more transmission / reception points (TRPs). That is, the base station may transmit signals using one or more of the associated TRPs. In one example, a base station may transmit one or more CSI-RSs using two or more TRPs (e.g., two TRPs) and one or more CSI-RSs using a single TRP. Here, the UE may transmit CSI reports associated with both single-TRP measurements and joint-TRP measurements.

[0047]

[0062] For example, a UE may receive (e.g., from a base station) control signaling indicating a first subset of CMRs from a set of CMRs for single-TRP measurements associated with a first TRP, a second subset of CMRs from a second set of CMRs for single-TRP measurements associated with a second TRP, and one or more CMR pairs for joint TRP measurements. Here, each CMR pair may include one CMR from the first subset (e.g., associated with the first TRP) and one CMR from the second subset (e.g., associated with the second TRP). The UE may then monitor the indicated CMRs (e.g., the first subset, the second subset, and one or more CMR pairs) to generate a set of measurements for CSI. The UE may transmit a CSI report indicating one or more channel resource indicators associated with at least one of the sets of measurements. In some cases, the UE may indicate one or more channel resource indicators within a number of bits based on the number of CMR pairs indicated by the control signaling. That is, the code space associated with the number of bits (e.g., the number of possible CMRs indicated by each channel resource indicator) may be based on the number of CMR pairs, and therefore the number of bits indicating the channel resource indicator may also be based on the number of CMR pairs.

[0048]

[0063] In another example, the described techniques provide for a UE to transmit a CSI report associated with both single-TRP measurements and joint-TRP measurements, where the UE shares a precoding matrix indicator (PMI) and a rank indicator (RI) between the CSI measurements associated with both the single-TRP measurements and the joint-TRP measurements. For example, the UE may receive control signaling indicating a pair of CMRs and that first and second PMIs and first and second RIs calculated for channel measurements associated with the CMR pair can be shared to individually generate a channel measurement (e.g., a channel quality indicator (CQI)) for each CMR in the pair of CMRs. The UE may monitor the pair of CMRs to generate joint-TRP CSI (e.g., including the first and second PMIs and the first and second RIs). The UE may further generate a first single TRP CSI associated with the first TRP including the first PMI and the first RI and a second single TRP CSI associated with the second TRP including the second PMI and the second RI. The UE may then transmit a CSI report including CQI associated with both the joint TRP and the single TRP generated using the shared PMI, the shared RI, or both.

[0049]

[0064] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are then described in the context of CMR configurations, CSI reporting, process flows, and CSI schemes. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to CSI reporting using single and joint TRP measurements.

[0050]

[0065] 1 illustrates an example of a wireless communication system 100 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications using low-cost and low-complexity devices, or any combination thereof.

[0051]

[0066] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different types or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base station 105 and the UEs 115 may support communication of signals via one or more radio access technologies.

[0052]

[0067] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be fixed, mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in FIG. 1.

[0053]

[0068] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface). The base stations 105 may communicate with each other over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0054]

[0069] One or more of the base stations 105 described herein may include or be referred to by those skilled in the art as a base transceiver station, radio base station, access point, radio transceiver, Node B, eNode B (eNB), Next Generation Node B or GigaNode B (any of which may be referred to as gNB), Home Node B, Home eNode B, or other suitable terminology.

[0055]

[0070] The UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable terminology, where a “device” may also be referred to as a unit, station, terminal, or client, among other examples. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine-type communication (MTC) device, among other examples, which may be implemented in various objects, such as an appliance, a vehicle, a meter, or the like.

[0056]

[0071] The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as shown in FIG. 1, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples.

[0057]

[0072] The UE 115 and the base station 105 may wirelessly communicate with each other via one or more communication links 125 via one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates the operation of the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0058]

[0073] A signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system utilizing MCM techniques, a resource element may be composed of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing have an inverse relationship. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements and the higher the order of the modulation scheme that the UE 115 receives, the higher the data rate of the UE 115 may be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.

[0059]

[0074] The time interval for the base station 105 or the UE 115 may be, for example, T s =1 / (Δf max N f ) seconds, where Δf max may represent the maximum supported subcarrier spacing, and N f may represent the maximum supported discrete Fourier transform (DFT) size. The communication resource time intervals may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0060]

[0075] Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into several slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include several symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). In some wireless communications systems 100, a slot may be further divided into multiple minislots, each containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the frequency operating band.

[0061]

[0076] A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of wireless communication system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0062]

[0077] Physical channels may be multiplexed on carriers according to various techniques. Physical control channels and physical data channels may be multiplexed on downlink carriers using, for example, one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by several symbol periods and may span the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESET) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, where each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level for the control channel candidates may refer to several control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a particular UE 115.

[0063]

[0078] In some examples, the base stations 105 are mobile and may therefore provide communication coverage to moving geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include a heterogeneous network in which different types of base stations 105 provide coverage to various geographic coverage areas 110, for example, using the same or different radio access technologies.

[0064]

[0079] The wireless communication system 100 may be configured to support ultra-reliable or low-latency communications, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communications (URLLC) or mission-critical communications. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communications may include private or group communications and may be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include service prioritization, and the mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0065]

[0080] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication occurs between UEs 115 without the involvement of the base station 105.

[0066]

[0081] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) that may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management, for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be forwarded through the user plane entity, which may provide IP address allocation and other functions. The user plane entities may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, intranet(s), IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0067]

[0082] Some of the network devices, such as the base station 105, may include sub-components such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio head, a smart radio head, or a TRP. Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or integrated into a single network device (e.g., the base station 105).

[0068]

[0083] The wireless communication system 100 may operate using one or more frequency bands typically ranging from 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the 300 MHz to 3 GHz region is known as the ultra-high frequency (UHF) region or decimeter band because wavelengths range from approximately 1 decimeter to 1 meter in length. Although UHF waves may be blocked or redirected by buildings and environmental features, the waves may penetrate structures sufficiently for a macrocell to provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0069]

[0084] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U), or NR technology in an unlicensed band, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. Devices such as the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance when operating in the unlicensed radio frequency spectrum band. In some examples, operation in the unlicensed band may be based on a carrier aggregation configuration with component carriers operating in a licensed band (e.g., LAA). Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0070]

[0085] The base station 105 or the UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or the UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 can use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted through the antenna ports.

[0071]

[0086] The base station 105 or UE 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques are sometimes referred to as spatial multiplexing. Multiple signals may be transmitted by a transmitting device, for example, via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0072]

[0087] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference and others experience destructive interference. Adjusting signals communicated via antenna elements may include the transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. The adjustment associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device or to some other orientation).

[0073]

[0088] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform a beamforming operation for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used to identify beam directions (e.g., by a transmitting device such as the base station 105 or by a receiving device such as the UE 115) for subsequent transmission or reception by the base station 105.

[0074]

[0089] Some signals, such as data signals associated with a particular receiving device, may be transmitted by the base station 105 in a single beam direction (e.g., a direction associated with the receiving device, such as the UE 115). In some examples, the beam direction associated with transmission along the single beam direction may be determined based on signals transmitted in one or more beam directions. For example, the UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and may report to the base station 105 an indication of the signal that the UE 115 received with the best or otherwise acceptable signal quality.

[0075]

[0090] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a composite beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands.

[0076]

[0091] The base station 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), CSI-RS), which may be precoded or precoded. The UE 115 may provide feedback (e.g., via a CSI report) for beam selection, which may be PMI or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques have been described with respect to signals transmitted by the base station 105 in one or more directions, the UE 115 may employ similar techniques to transmit a signal multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by the UE 115) or to transmit a signal in a single direction (e.g., to transmit data to a receiving device).

[0077]

[0092] In an example of the wireless communication system 100, the base station 105 may transmit one or more reference signals (e.g., CRS, CSI-RS) to the UE 115. The UE 115 may measure one or more CMRs (e.g., associated with the CSI-RS) to generate a CSI report for transmission to the base station 105. For example, the UE 115 may indicate to the base station 105 within the CSI report one or more resources associated with better measurement quality (e.g., compared to other resources associated with the CMRs) for future communications between the base station 105 and the UE 115. In some cases, the base station 105 may be associated with two or more TRPs 145. That is, the base station 105 may transmit signals using one or more of the associated TRPs 145. In one example, the base station 105 may transmit one or more CSI-RSs using two or more TRPs 145 (e.g., two TRPs) and transmit one or more CSI-RSs using a single TRP 145. Here, the UE 115 may transmit CSI reports related to both single and joint TRP measurements.

[0078]

[0093] In some cases, a fading emulator MIMO (FeMIMO) device may utilize multiple TRP (mTRP) CSI. For example, an mTRP CSI report (e.g., a non-coherent joint transmission (NCJT) CSI report) may correspond to a CSI report associated with two CMRs. That is, the mTRP CSI report may be configured with two corresponding transmission configuration indicator (TCI) states, each associated with two TRPs. Furthermore, within a CSI-RS resource set in a given CSI reporting configuration, one or more pairs of CSI-RS resources may be configured for one or more NCJT CSI hypotheses. That is, the CMRs may be divided into two groups, and each CMR pair (e.g., corresponding to an NCJT CSI hypothesis) may include one CMR from the first group (e.g., associated with the first TRP) and one CMR from the second group (e.g., associated with the second TRP). Furthermore, a number (e.g., “N”) (e.g., for the UE 115 to measure) may be configured from all possible pairs of CMRs. In some cases, the base station 105 may configure each CMR for both the NCJT hypothesis and the single-TRP hypothesis (e.g., associated with mTRP CSI).

[0079]

[0094] In some cases, for CSI measurements associated with a reporting configuration (e.g., CSI-ReportConfig) for an NCJT CSI assumption, the UE 115 may select a first number of CSI-RS resources in a CSI-RS resource set for the CMR (e.g., for a single TRP CSI report) or a CMR (e.g., “K s 'NZP CSI-RS resources, where K s ≧2) and a second number of CSI-RS resource pairs or CMR pairs (e.g., “N” NZP CSI-RS resource pairs, where N≧1) used for NCJT measurement hypotheses. Here, the UE 115 may be configured with two CMR groups, where the first number of CMRs (e.g., K s ) is the sum of the amount of CMR in each of the two CMR groups (e.g., K s=K1+K2), where K1≧2 and corresponds to the number of CMRs in a first CMR group associated with a first TRP, and K2≧2 and corresponds to the number of CMRs in a second CMR group associated with a second TRP. In some cases, the UE 115 may be configured to measure CMRs for both single TRP CSIs and multiple TRP CSIs.

[0080]

[0095] Based on configuring the UE 115 with two CMR groups, the UE 115 may be configured with CMR pairs (e.g., the UE 115 may determine a CMR pair). In one example, the UE 115 may be configured with several CMR pairs (e.g., N CMR pairs) based on a higher layer configuration that selects several CMR pairs from all possible pairs. For example, the UE 115 may receive a bitmap indicating several CMR pairs from all possible CMR pairs. Additionally or alternatively, the UE 115 may receive control signaling (e.g., radio resource control (RRC) signaling, medium access control-control element (MAC-CE)) indicating several CMR pairs from all possible CMR pairs. In some cases, the UE 115 may determine CSI processing unit (CPU), resource, and port occupancy associated with CSI reporting separately for the NCJT assumption and the single-TRP assumption.

[0081]

[0096] Based on being configured for both the single-TRP assumption and the NCJT assumption, the UE 115 may report CSI associated with the single and joint TRPs (e.g., by transmitting a CSI report). In one example, the UE 115 may report CSI for the NCJT assumption separately from the single-TRP assumption. Here, the UE 115 may report one CSI for all configured NCJT assumptions (e.g., corresponding to all “N” CMR pairs) and a number (e.g., “X”) of CSIs for all configured single-TRP assumptions (e.g., corresponding to all single CMRs). The number of CSIs reported for the configured single-TRP assumptions may be indicated to the UE 115 (e.g., by control signaling) and may be equal to 0, 1, or 2. That is, “X” may be equal to 0, 1, or 2. In another example, the UE 115 may report CSI associated with the best assumption (e.g., corresponding to the CMR associated with the best measured signal quality and lowest measurement noise) of all assumptions (e.g., from the single-TRP assumption and the NCJT assumption).

[0082]

[0097] In either option, the UE 115 may be configured to report one or more parameters in a CSI report associated with the single-TRP hypothesis, the NCJT hypothesis, or both. In the case of NCJT CSI, the UE 115 may include in the first part of the CSI report (e.g., in CSI Part 1) a single CSI-RS resource indicator (CRI) that identifies the CMR pair corresponding to the CSI report, two rank indicators for each of the two CMRs in the CMR pair, and one CQI. Additionally, the UE 115 may include two PMIs and two layer indicators (LIs) in the second part of the CSI report (e.g., in CSI Part 2). For each of the number (e.g., “X”) of single-TRP CSIs that the UE 115 is configured to report, the UE 115 may include the CRI, RI, and CQI in the first part of the CSI report (e.g., in CSI Part 1) and the PMI and LI in the second part of the CSI report (e.g., in CSI Part 2).

[0083]

[0098] The CSI reporting may occupy a certain number of CPUs at the UE 115, where the number of CPUs is based on the amount of reporting in the CSI reporting (e.g., based on the number of single TRP CSIs “X”, based on the number of NCJT hypotheses “N”). For example, with a CSI-RS-ResourceSet with upper layer parameter trs-Info configured, the number of CPUs occupied by the UE 115 when the number of CSI reporting is 0 may be 0. When the number of configured CSI reporting corresponds to cri-RSRP, ssb-Index-RSRP such as L1-RSRP reporting, or none such as receive beam sweeping, the number of CPUs occupied by the UE 115 may be 1. In another example, for wideband CSI with up to four ports in the CSI reporting, the UE 115 may occupy a number of CPUs equal to a defined number of occupied CPUs supported by the UE 115 (e.g., based on the capabilities of the UE 115). In another example, the number of CPUs occupied by the UE 115 may correspond to the number of CSI-RS resources (e.g., the number of CMRs) in the CSI-RS resource set for channel measurement (e.g., a CMR group).

[0084]

[0099] The UE 115 may be configured to refrain from updating the remaining CSI if the total number of CPUs occupied by the UE 115 exceeds a defined number of occupied CPUs supported by the UE 115 (e.g., based on the capabilities of the UE 115). Furthermore, a CSI report may be associated with active CSI-RS resources and active CSI-RS port occupancies. Here, the UE 115 may be configured to refrain from updating the remaining CSI if the total number of active CSI-RS resources exceeds a defined number of active CSI-RS resources supported by the UE 115 or the total number of active CSI-RS port occupancies associated with a CSI report exceeds a defined number of active CSI-RS port occupancies supported by the UE 115. In some cases, if a CSI-RS resource (e.g., a CMR) is referenced “N” times by one or more CSI reporting configurations, the CSI-RS resource and the CSI-RS ports within the CSI-RS resource may be counted “N” times.

[0085]

[0100] In an example of the wireless communication system 100, the UE 115 may be configured for both the single-TRP assumption and the NCJT assumption. For example, the UE 115 may receive control signaling indicating a first subset of CMRs from a set of CMRs (e.g., for the single-TRP assumption) for single-TRP measurements associated with a first TRP 145 (e.g., for the NCJT assumption), a second subset of CMRs from a second set of CMRs for single-TRP measurements associated with a second TRP 145, and one or more CMR pairs for joint-TRP measurements (e.g., for the NCJT assumption). Here, each CMR pair may include one CMR from the first subset (e.g., associated with the first TRP) and one CMR from the second subset (e.g., associated with the second TRP). The UE 115 may then monitor the indicated CMRs (e.g., the first subset, the second subset, and one or more CMR pairs) to generate a set of measurements for the CSI. The UE 115 may transmit a CSI report indicating one or more channel resource indicators associated with at least one of the sets of measurements. In some cases, the UE 115 may indicate the one or more channel resource indicators within a number of bits based on the number of CMR pairs indicated by the control signaling. That is, a code space associated with the number of bits (e.g., the number of possible CMRs indicated by each channel resource indicator) may be based on the number of CMR pairs, and therefore the number of bits indicating the channel resource indicator may also be based on the number of CMR pairs.

[0086]

[0101] In another example, the described techniques provide for the UE 115 to transmit CSI reports associated with both single-TRP measurements and joint-TRP measurements, where the UE 115 shares a PMI, an RI, or both between CSI measurements associated with both the single-TRP measurements and the joint-TRP measurements. For example, the UE 115 may receive control signaling (e.g., from the base station 105, from the TRP 145) indicating a pair of CMRs and that first and second PMIs and first and second RIs calculated for channel measurements associated with the CMR pair can be shared to individually generate channel measurements (e.g., CQIs) for each CMR in the pair of CMRs. The UE 115 may monitor the pair of CMRs to generate joint-TRP CSI (e.g., including the first and second PMIs and the first and second RIs). The UE 115 may further generate a first single TRP CSI associated with the first TRP 145 including the first PMI and the first RI, and a second single TRP CSI associated with the second TRP 145 including the second PMI and the second RI. The UE 115 may then transmit a CSI report including CQI associated with both the joint TRP and the single TRP generated using the shared PMI, the shared RI, or both.

[0087]

[0102] A receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals, such as synchronization signals, reference signals, beam selection signals, or other control signals, from the base station 105. For example, the receiving device may attempt multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of the antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receiving configuration may be aligned in a beam direction determined based on listening along different receiving configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening along multiple beam directions).

[0088]

[0103] 2 illustrates an example of a wireless communication system 200 that supports CSI reporting using single and joint TRP measurements in accordance with aspects of the present disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a base station 205 and a UE 215, which may be examples of the base station 105 and the UE 115, respectively, described with reference to FIG. 1.

[0089]

[0104] The UE 215 may be in communication with the base station 205. For example, the UE 215 and the base station 205 may exchange messages (e.g., CSI reports 225, CSI-RS 220) and signaling (e.g., control signaling 210). In some cases, the base station 205 may include or be associated with two or more TRPs 235. For example, the base station 205 may rely on multiple TRPs 235 (e.g., two) for communication with the UE 215. The base station 205 may send control signaling 210 to the UE 215, which may configure the UE 215 for subsequent communication with the base station 205. For example, the control signaling 210 may indicate to the UE 215 a first CMR group (e.g., associated with a first TRP 235-a of the base station 205) and a second CMR group (e.g., associated with a second TRP 235-b of the base station 205).

[0090]

[0105] The control signaling 210 may further indicate a first subset of CMRs in a first CMR group (e.g., associated with a first TRP 235-a associated with the base station 205). The first subset of CMRs may be associated with CMRs that the UE 215 should monitor to generate a subsequent CSI report 225 (e.g., based on a single TRP CSI associated with the first TRP 235-a). The control signaling 210 may further indicate a second subset of CMRs in a second CMR group (e.g., associated with a second TRP 235-b associated with the base station 205). The second subset of CMRs may be associated with CMRs that the UE 215 should monitor to generate a subsequent CSI report 225 (e.g., based on a single TRP CSI associated with the second TRP 235-b). The control signaling 210 may further indicate one or more CMR pairs including a CMR from a first CMR group (e.g., corresponding to a first TRP 235-a associated with the base station 205) and a CMR from a second CMR group (e.g., corresponding to a second TRP 235-b associated with the base station 205). The one or more pairs of CMRs may be associated with pairs of CMRs that the UE 215 should monitor to generate a subsequent CSI report 225 (e.g., based on the NCJT CSI associated with the first and second TRPs 235).

[0091]

[0106] The control signaling 210 may further indicate a configuration for the CSI report 225. That is, the control signaling 210 may indicate the amount of CRI 230 to be included in the CSI report 225. In one option, the control signaling 210 may configure the UE 215 to indicate a single CRI 230 in the CSI report 225. Here, the single CRI 230 included in the CSI report 225 may indicate one of the CMRs from the first subset, the second subset, and one or more CMR pairs. That is, the single CRI 230 may indicate a CMR associated with the highest measured signal quality (e.g., from the first subset, the second subset, and one or more CMR pairs). In another option, the control signaling 210 may configure the UE 215 to indicate two CRIs 230 in the CSI report 225. Here, the first CRI 230-a may indicate a CMR pair (e.g., from one or more CMR pairs) associated with the highest measured signal quality, and the second CRI 230-b may indicate a CMR (e.g., from a first subset and a second subset) associated with the highest measured signal quality. In another option, the control signaling 210 may configure the UE 215 to indicate three CRIs 230 in the CSI report. Here, the first CRI 230-a may indicate a CMR pair (e.g., from one or more CMR pairs) associated with the highest measured signal quality, the second CRI 230-b may indicate a CMR associated with a first TRP 235-a (e.g., from the first subset) associated with the highest measured signal quality, and the third CRI 230-b may indicate a CMR associated with a second TRP 235-b (e.g., from the second subset) associated with the highest measured signal quality.

[0092]

[0107] Based on transmitting the control signaling 210, the base station 205 may transmit one or more CSI-RS 220 to the UE 215. For example, the base station 205 may transmit the CSI-RS 220 via each of the CMRs indicated in the first subset, the second subset, and one or more CMR pairs. That is, the base station 205 may use a first TRP 235-a associated with the base station 205 to transmit the CSI-RS 220 via each of the first subset of CMRs. Furthermore, the base station 205 may use a second TRP 235-b associated with the base station 205 to transmit additional CSI-RS 220 via each of the second subset of CMRs. Furthermore, the base station 205 may use both the first and second TRPs 235 associated with the base station 205 to transmit the CSI-RS 220 via each of the one or more pairs of CMRs.

[0093]

[0108] In accordance with the control signaling 210, the UE 215 may monitor a first subset of CMRs, a second subset of CMRs, and one or more CMR pairs. The UE 215 may then generate a set of measurements (e.g., a CQI) based on monitoring the first subset, the second subset, and one or more CMR pairs. For example, the UE 215 may identify one or more CMRs associated with the best signal quality (e.g., highest SNR, lowest interference) (e.g., from the first subset, the second subset, and one or more CMR pairs).

[0094]

[0109] Based on performing the set of measurements (e.g., on the CSI-RS 220), the UE 215 may transmit a CSI report 225 to the base station 205. The CSI report 225 may include one or more CRIs 230. That is, the UE 215 may transmit to the base station 205 one or more CRIs 230 each indicating a respective CMR (e.g., from the first subset, the second subset, or one or more CMR pairs) that has the highest measured signal quality (e.g., compared to the measured signal qualities of the remaining CMRs in the first subset, the second subset, and the one or more CMR pairs).

[0095]

[0110] In some cases, the number of bits in each field of the CSI report 225 indicating the CRI 230 is based on the number of possible CMRs (e.g., the number of CRI codepoints) indicated by the CRI 230. For example, the number of bits B indicating the CRI 230 may be represented by Equation 1 shown below: In the example of Equation 1, C may correspond to the number of CRI codepoints (e.g., the number of possible CMRs indicated by the CRI 230).

[0096]

number

[0097]

[0111] For example, if the UE 215 is configured (e.g., by control signaling 210) to transmit a single CRI 230-a to the base station 205, the single CRI 230-a may indicate a first subset of CMRs, a second subset of CMRs, and one CMR from one or more CMR pairs. That is, the CRI 230-a may indicate a CMR among the NCJT measurement assumption and the single-TRP measurement assumption. Thus, the bit size of the CRI 230-a may depend on the total number of CMR pairs (e.g., the number of one or more CMR pairs) in the case of the NCJT measurement assumption, and on the total number of valid CMRs (e.g., the number of CMRs in the first subset of CMRs and the second subset of CMRs) in the case of the single-TRP measurement assumption.

[0098]

[0112] In another example, the UE 215 may be configured (e.g., by the control signaling 210) to transmit two CRIs 230 (e.g., CRI 230-a and CRI 230-b). Here, CRI 230-a may indicate one of one or more pairs of CMRs, and CRI 230-b may indicate one of the CMRs from a first subset of CMRs and a second subset of CMRs. That is, CRI 230-a may be for an NCJT measurement assumption, where the number of bits for indicating CRI 230-a may be based on the number of valid CMR pairs (e.g., the number of one or more CMR pairs) for the NCJT measurement assumption. Furthermore, CRI 230-b may be for a single-TRP measurement assumption, where the number of bits for indicating CRI 230-b may be based on the number of valid CMRs (e.g., the number of CMRs in the first subset and the second subset) for the single-TRP measurement assumption.

[0099]

[0113] In another example, the UE 215 may be configured (e.g., by the control signaling 210) to transmit three CRIs 230 (e.g., CRI 230-a, CRI 230-b, and CRI 230-c). Here, CRI 230-a may indicate one of one or more pairs of CMRs, CRI 230-b may indicate a CMR from a first subset of CMRs, and CRI 230-c may indicate a CMR from a second subset of CMRs. In this example, CRI 230-a may be for an NCJT measurement assumption, and the number of bits to indicate CRI 230-a may be based on the number of valid CMR pairs (e.g., the number of one or more CMR pairs) for the NCJT measurement assumption. Furthermore, CRI230-b may be for a single TRP hypothesis associated with a first TRP 235-a, and the number of bits for indicating CRI230-b may be based on the number of valid CMRs for the single TRP measurement hypothesis associated with the first TRP 235-a (e.g., the number of CMRs in the first subset). Furthermore, CRI230-c may be for a single TRP hypothesis associated with a second TRP 235-b, and the number of bits for indicating CRI230-c may be based on the number of valid CMRs for the single TRP measurement hypothesis associated with the second TRP 235-b (e.g., the number of CMRs in the second subset).

[0100]

[0114] FIG. 3A illustrates an example of a CMR configuration 300 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. Furthermore, FIG. 3B illustrates an example of a CSI report 301 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. In some cases, the CMR configuration 300 may be an example of a CMR configuration indicated to a UE by a base station (e.g., via control signaling) as described with reference to FIGS. 1 and 2. Furthermore, the CSI report 301 may be an example of a CSI report transmitted by a UE to a base station as described with reference to FIGS. 1 and 2. In some cases, the UE may be configured with the CMR configuration 300, may monitor resources for CSI-RS based on the CMR configuration 300, and may transmit the CSI report 301 (e.g., to a base station) based on monitoring resources associated with the CMR configuration 300.

[0101]

[0115] 3A shows a CMR configuration 300 including a CMR group 305-a and a CMR group 305-b. In some cases, the CMR group 305-a may be a set of CMRs 310 associated with a first TRP (e.g., associated with a base station). That is, the base station may transmit a reference signal (e.g., CSI-RS, CRS) via one of the CMRs 310 in the CMR group 305-a using the first TRP. Furthermore, the CMR group 305-b may be a set of CMRs 310 associated with a second TRP (e.g., associated with a base station). Here, the base station may transmit a reference signal via one of the CMRs 310 in the CMR group 305-b using the second TRP. In some cases, the base station may indicate the CMR group 305 to the UE via control signaling (e.g., RRC signaling).

[0102]

[0116] The base station may indicate (e.g., by control signaling) a subset of CMRs 310 in the CMR group 305-a for the UE to monitor a single TRP CSI report associated with a first TRP, a subset of CMRs 310 in the CMR group 305-b for the UE to monitor a single TRP CSI report associated with a second TRP, and one or more CMR pairs 315-a for the UE to monitor a joint TRP CSI report.

[0103]

[0117] To configure a first subset of CMRs 310 from CMR group 305-a and a second subset of CMRs 310 from CMR group 305-b, the base station first selects some of the CMRs 310 (e.g., K s In some cases, the CMR group 305-a includes a first number of CMRs 310 (e.g., K1 CMRs 310), and the CMR group 305-b includes a second number of CMRs 310 (e.g., K2 CMRs 310). The total number of CMRs 310 (e.g., K s CMRs 310) and the number of CMRs 310 in each CMR group (e.g., K s CMR310 and K s The CMRs 310) can be related as shown below in Equation 2:

[0104]

number

[0105]

[0118] Based on configuring the CMR group 305-a and the CMR group 305-b, the base station may indicate to the UE CMR pairs 315 for joint TRP CSI reporting. In one example, the base station may indicate the CMR pairs 315 by indicating (e.g., via control signaling) the number of CMR pairs 315 (e.g., N CMR pairs 315) that the UE will monitor for joint TRP CSI reporting. In the example CMR configuration 300, the base station may indicate that the number of CMR pairs 315 that the UE will monitor is two (e.g., N=2). The UE may identify the CMR pairs 315-a and 315-b by selecting a CMR 310 from each CMR group 305 according to the order of the CMRs 310 (e.g., corresponding to the index of the CMRs 310). For example, the UE may identify the CMR pairs 315 by selecting a first CMR 310 from each CMR group 305 for a first CMR pair 315-a (e.g., including CMR 310-a and CMR 310-d) and selecting a second CMR 310 from each CMR group 305 for a second CMR pair 315-b.

[0106]

[0119] Based on configuring the CMR groups 305-a and 305-b and configuring the CMR pair 315, the base station may configure a first subset of CMRs 310 from the CMR group 305-a (e.g., to determine a single TRP CSI measurement associated with a first TRP) and a second subset of CMRs 310 from the CMR group 305-b (e.g., to determine a single TRP CSI measurement associated with a second TRP). The first subset of CMRs 310 from the first CMR group 305-a may include M1 CMRs 310, and the second subset of CMRs 310 from the second CMR group 305-b may include M2 ​​CMRs 310. The subset of CMRs 310 and CMR pairs 315 that the UE is configured to monitor for a single TRP CSI report may be based on whether sharing the CMR 310 between a single TRP CSI report and a joint TRP CSI report (e.g., configured for the UE by the base station via control signaling) is enabled. In some cases, whether a CMR 310 can appear in a CMR pair 315 in addition to a subset of CMRs 310 (e.g., sharing the CMR 310 between a single TRP report and a joint TRP report) may be based on the capabilities of the UE (e.g., within a frequency distance, such as within a frequency distance that includes millimeter-wave frequencies between 24.25 GHz and 52.6 GHz).

[0107]

[0120] When sharing is enabled, the UE may be configured to monitor the same CMR 310 for both single-TRP CSI reporting and joint-TRP CSI reporting. For example, the UE may be configured to monitor the CMR 310-a for the single-TRP CSI reporting (e.g., the base station may indicate that the CMR 310-a is part of a first subset associated with a first TRP) and may be configured to monitor the CMR 310-a for the joint-TRP CSI reporting (e.g., as part of a CMR pair 315-a including a CMR 310-a from a CMR group 305-a and a CMR 310-d from a CMR group 305-b). When sharing is disabled, the UE may be configured to monitor a different CMR 310 for the single-TRP CSI reporting than for the joint-TRP CSI reporting. That is, if the CMR 310-b is configured as part of the CMR pair 315-b, the UE may be configured to refrain from monitoring the CMR 310-b for the single-TRP CSI reporting associated with the first TRP. That is, a first subset of CMRs 310 associated with a first TRP may not include CMR 310-b (because CMR 310-b is part of CMR pair 315-b, which includes CMR 310-b and CMR 310-e).

[0108]

[0121] In one example, to configure each of the subsets of CMRs 310 (e.g., a first subset of CMR group 305-a, a second subset of CMR group 305-b), the base station may send additional control signaling (e.g., RRC signaling) to the UE indicating the CMRs 310 in the first subset of CMR group 305-a and the CMRs 310 in the second subset of CMR group 305-b. That is, the base station may indicate K1 to M1 CMRs 310 in the first CMR group 305-a for the first subset of CMRs 310. Additionally, the base station may indicate K2 to M2 CMRs 310 in the second CMR group 305-b for the second subset of CMRs 310. For this example where sharing CMRs for joint TRP CSI reporting and single TRP CSI reporting is enabled, the base station may transmit control signaling indicating that a first subset of CMRs 310 includes CMR 310-a and a second subset of CMRs 310 includes CMR 310-f. For another example where sharing CMRs for joint TRP CSI reporting and single TRP CSI reporting is not enabled, the base station may transmit control signaling indicating that a first subset of CMRs 310 includes CMR 310-c and a second subset of CMRs 310 includes CMR 310-f.

[0109]

[0122] In another example, to configure each of the subsets of CMRs 310 (e.g., a first subset of CMR group 305-a, a second subset of CMR group 305-b), the base station may indicate (e.g., via RRC signaling) whether sharing of CMRs 310 between joint TRP CSI reporting and single TRP CSI reporting is enabled. If the base station indicates that sharing of CMRs 310 between joint TRP CSI reporting and single TRP CSI reporting is enabled, the UE may determine that each subset includes all of the CMRs 310 associated with that TRP. That is, the base station may transmit RRC signaling that enables sharing of CMRs 310 (e.g., between the NCJT assumption and the single TRP assumption), and the UE may determine that all of the CMRs 310 in the first CMR group 305-a and the second CMR group 305-b are enabled. For example, the UE may transmit RRC signaling that enables sharing of CMRs 310 between joint TRP CSI reporting and single TRP CSI reporting. s The UE may determine that the number of CMRs 310 associated with the first TRP (e.g., the K+K CMRs described in Equation 2) are valid single-TRP hypotheses. That is, the UE may determine that the number of CMRs 310 in the first subset of the first CMR group 305-a is the same as the number of CMRs in the first CMR group 305-a (e.g., M=K), and that the number of CMRs 310 in the second subset of the second CMR group 305-b is the same as the number of CMRs in the second CMR group 305-b (e.g., M=K). Here, (e.g., for the CMR configuration 300), the UE may determine that the first subset of CMRs 310 associated with the first TRP may include CMRs 310-a, CMR 310-b, and CMR 310-c (e.g., all of the CMRs 310 in the CMR group 305-a associated with the first TRP).

[0110]

[0123] For this example, where the base station indicates that sharing of CMRs 310 between joint TRP CSI reporting and single-TRP CSI reporting is disabled, the UE may determine that the subset includes CMRs 310 in each CMR group 305 that are distinct from the CMRs 310 in the CMR pairs 315. That is, the base station may send RRC signaling to disable sharing of CMRs 310 (e.g., between the NCJT assumption and the single-TRP assumption). The UE may then determine the number of CMRs 310 in the first CMR group 305-a that appear in any of the CMR pairs 315 (e.g., N1 CMRs 310) and the number of CMRs 310 in the second CMR group 305-b that appear in any of the CMR pairs 315 (e.g., N2 CMRs 310). In cases where CMRs 310 are not shared between CMR pairs 315 (e.g., each CMR pair 315 includes a separate CMR as shown in the example CMR configuration 300), the number of CMRs 310 from each CMR group 305 that are in the CMR pair 315 (e.g., N1 and N2 for CMR groups 305-a and 305-b, respectively) may be the same as the number of CMR pairs 315 (e.g., N CMR pairs 315). In some other cases where CMRs 310 are shared between CMR pairs 315, the number of CMRs 310 from each CMR group 305 that are in the CMR pair 315 may be less than or equal to the number of CMR pairs 315. Based on determining the number of CMRs 310 that are in the CMR pair (e.g., N1 and N2 for CMR groups 305-a and 305-b, respectively), the UE may determine the number of CMRs 310 in each of the subsets. That is, the UE may determine that the number of CMRs 310 in the first subset of the first CMR group 305-a is the difference between the number of CMRs in the first CMR group 305-a (e.g., M1 = K1 - N1), and that the number of CMRs 310 in the second subset of the second CMR group 305-b is the difference between the number of CMRs 310 in the second CMR group 305-b and the number of CMRs 310 from the first CMR group 305-b in the CMR pair 315 (e.g., M2 = K2 - N2).

[0111]

[0124] Here, (e.g., in the case of the CMR configuration 300), the UE may determine that a first subset of CMRs 310 (e.g., associated with a first TRP and including CMRs 310 from a first CMR group 305-a) includes CMR 310-c based on CMR 310-c being distinct from CMRs 310 in the CMR group 305-a associated with a CMR pair 315 (e.g., CMRs 310-a and 310-b). Further, the UE may determine that a second subset of CMRs 310 (e.g., associated with a second TRP and including CMRs 310 from a second CMR group 305-b) includes CMR 310-f based on CMR 310-f being distinct from CMRs 310 in the CMR group 305-f associated with a CMR pair 315 (e.g., CMRs 310-d and 310-e).

[0112]

[0125] In another example, to configure each of the subsets of CMRs 310 (e.g., a first subset of CMR group 305-a, a second subset of CMR group 305-b), the base station may send additional control signaling (e.g., RRC signaling) to the UE indicating the same value for the identifier of the CMRs 310 configured for joint CSI reporting (e.g., a CMR pair 315) and a single CMR 310 (e.g., a single CMR 310 in a CMR group 305). For example, if the CMR configuration 300 supports sharing a CMR 310 between joint CSI reporting and single CSI reporting, the first subset may include the CMR 310-a based on the base station assigning the same identifier to the CMR 310-a as the CMR pair 315-a. Here, the base station may update the subsets of CMRs 310 by reconfiguring the CMR configuration 300 (e.g., by reconfiguring the identifiers of the CMRs 310 in the CMR groups 305, by reconfiguring the identifiers of the CMR pairs 315). Here, the UE may determine the number of CMRs 310 in each of the subsets based on the number of CMR pairs 315 (e.g., N CMR pairs 315). That is, the UE may determine that the number of CMRs 310 in a first subset of a first CMR group 305-a is the difference between the number of CMRs 310 and the number of CMR pairs 315 in the first CMR group 305-a (e.g., M=K−N), and that the number of CMRs 310 in a second subset of a second CMR group 305-b is the difference between the number of CMRs 310 and the number of CMR pairs 315 in the second CMR group 305-b (e.g., M=K−N). That is, the first N CMRs 310 in each CMR group 305 may be used for a CMR pair 315, and therefore the CMRs 310 in each CMR group 305 may be used for a single TRP CSI report (e.g., may be in a first subset or a second subset).

[0113]

[0126] 3B shows an example CSI report 301. The UE may generate the CSI report 301 in response to monitoring a CMR 310 according to a CMR configuration 300 configured by a base station. The CSI report 301 may include one or more CRIs 330, where each CRI 330 indicates a CMR 310 associated with a higher measured signal quality than other CMRs 310 associated with the CRI 330.

[0114]

[0127] The number of bits indicating each CRI 330 may be based on the number of possible CMRs 310 indicated by each CRI 330 (e.g., C possible CMRs 310) as described in Equation 1. In particular, the number of bits indicating a CRI 330 (e.g., CRI codepoint or bit width of a CRI in a CSI report 301) associated with a CSI reporting configuration that includes two CMR groups 305 in one CMR resource set may be based on the number of CMRs 310 in both groups (e.g., K s ) the number of CMRs 310 in each group (e.g., K1 and K2), and the number of CMR pairs 315 (e.g., N). Additionally or alternatively, the number of bits indicating the CRI 330 may be based on the number of subsets of CMRs 310 configured for a single TRP hypothesis as individual CMRs 310 in the first CMR group 305-a and in the second CMR group 305-b, and across both CMR groups 305, which may be based on how the subsets of CMRs 310 are configured. Furthermore, the number of bits indicating the CRI 330 may be based on whether the UE is configured to report one CSI 301 associated with the best one of the NCJT hypothesis and the single TRP hypothesis (e.g., one CRI 330 is reported) or whether it is configured to report X CSIs associated with the single TRP hypothesis and one CSI associated with the NCJT hypothesis, where the configured value of X may be 0, 1, or 2 and X+1 CRIs 330 are reported. Thus, the number of bits representing each CRI 330 is based on the number of CRIs 330 in the CSI report 301, the number of CRMs 310 in each subset of the CRM group 315, and the number of CRM pairs 315.

[0115]

[0128] For example, the UE is configured to include a single CRI 330-a in the CSI report 301 that indicates any of the CMRs 310 in a first subset of the first CMR group 305-a, any of the CMRs 310 in a second subset from the second CMR group 305-b, and any of the CMR pairs 315. Here, as described below in Equation 3, the number of possible CMRs 310 (e.g., C possible CMRs 310) indicated by the CRI 330-a may be based on the number of CMRs 310 in the first subset (e.g., M CMRs 310), the number of CMRs 310 in the second subset (e.g., M CMRs 310), and the number of CMR pairs 315 (e.g., N CMR pairs 315).

[0116]

[0117]

[0129] If the UE is configured to include a single CRI 330-a in the CSI report 301 indicating one of the CMR pairs 315, the number of possible CMRs 310 indicated by the CRI 330-a (e.g., C possible CMRs 310) may be based on the number of CMR pairs 315 (e.g., N CMR pairs 315), as described below in Equation 4.

[0118]

number

[0119]

[0130] If the UE is configured to include two CRIs 330-a and 330-b in the CSI report 301, the CRI 330-a may indicate any of the CMR pairs 315, and the CRI 330-b may indicate any of the CMRs 310 in the first subset or the second subset. Here, the number of possible CMRs 310 indicated by the CRI 330-a may correspond to Equation 4. Further, the number of CMRs 310 indicated by the CRI 330-b may be described below in Equation 5.

[0120]

number

[0121]

[0131] If a UE is configured to include three CRIs 330-a, 330-b, and 330-c, CRI 330-a may indicate any of the CMR pairs 315, CRI 330-b may indicate any of the CMRs 310 in the first subset, and CRI 330-c may indicate any of the CMRs 310 in the third subset, where CRI 330-a may indicate one CMR pair 315 from the possible number of CMR pairs 315 defined in Equation 4. Furthermore, CRI 330-b may indicate M possible CMRs 310 as described in Equation 6.

[0122]

[0123]

[0132] Furthermore, CRI 330-c may represent M2 possible CMRs 310 as described in Equation 7.

[0125]

[0133] In some cases, additional RRC signaling may be required to measure M (M≦K) CSI-RSs from each CSI-RS resource set (e.g., from each CMR group 305) for the single TRP measurement assumption. s ) is used to configure the UE with the CMR 310. In a first option, the UE may be configured to report X CSIs associated with a single TRP hypothesis and one CSI associated with an NCJT hypothesis, where the configured value of X may be, for example, 0, 1, or 2, resulting in a CSI report including X+1 CSIs. In a second option, the UE may be configured to report a single CSI associated with the NCJT hypothesis and the single TRP hypothesis (e.g., the best or highest CSI).

[0126]

[0134] If additional RRC signaling selects M1 CMRs 310 (out of K1 CMRs) from the first CMR group 305-a and M2 CMRs 310 (out of K2 CMRs 310) from the second CMR group 305-b for a single TRP assumption, then in the second option, the number of CRI code points is C=M1+M2+N (e.g., as described with respect to Equation 3). For example, if two NCJT hypotheses are configured (e.g., N=2) corresponding to CMR pair 315-a (e.g., including CMRs 310-a and 310-d) and CMR pair 315-b (e.g., including CMRs 310-b and 310-e), and additional RRC signaling indicates that a single TRP measurement hypothesis corresponds to CMRs 310-a, 310-c, and 310-f, the number of code points may be five, and thus the CSI report 301 may include three bits (e.g., in CRI 330-a) to cover five code points (e.g., C=2+1+2).

[0127]

[0135] In another example, if additional RRC signaling selects M1 CMRs 310 (out of K1 CMRs) from a first CMR group 305-a and M2 CMRs 310 (out of K2 CMRs 310) from a second CMR group 305-b for a single TRP hypothesis, in the first option, the number of CRI code points may depend on the value of X (e.g., the UE is configured to report X CSIs associated with the single TRP hypothesis). If X=0 (one CRI 330 is reported), then C=N (e.g., as described with respect to Equation 4). If X=1 (two CRIs 330 are reported), then C1=N and C2=M1+M2 (e.g., as described with respect to Equation 5). If X=2 (three CRIs 330 are reported), then C1=N, C2=M1, and C3=M2. In one example, if two NCJT hypotheses corresponding to CMR pair 315-a and 315-b are configured (e.g., N=2) and additional RRC signaling indicates that a single TRP measurement hypothesis corresponds to CMRs 310-a, 310-c, and 310-f, then if X=0 (one CRI 330), then C=2, and thus the CSI report may include one bit to cover two possible codepoints. If X=1 (two CRIs), then C1=2 (one bit) and C2=2+1=3 (two bits), and thus the CSI report may include two CRIs 330 (e.g., two CRI fields), where the first field includes one bit and the second field includes two bits. If X=2 (three CRIs 330), then C1=2 (1 bit), C2=2 (1 bit), and C3=1 (0 bit, not reported as described with respect to Equation 1), and thus the CSI report 301 may include three CRIs 330 (e.g., three CRI fields), where the first field includes 1 bit, the second field includes 2 bits, and the third field includes 0 bit (e.g., the third field may be omitted from the CSI report 301). In other examples, the third field may include one or more bits and may be included in the CSI report 301.Note that other values ​​of N, M1, and M2 can be constructed and therefore result in a different number of code points in the above example.

[0128]

[0136] In some other cases, the base station may send additional RRC signaling to enable CMR sharing (e.g., between the NCJT assumption and the single-TRP assumption). In particular, in the case of a CMR 310 configured in a CSI-RS resource set, the base station may send RRC signaling to enable or disable the single-TRP measurement assumption using the CMR 310 configured in the CMR pair 315 for the NCJT measurement assumption. When sharing is enabled, one or more of the single-TRP measurement assumptions may use the CMR 310 included in the CMR pair 315 associated with the NCJT measurement assumption. In a first option, the UE may be configured to report X CSIs associated with the single-TRP assumption and one CSI associated with the NCJT assumption, where the configured value of X may be, for example, 0, 1, or 2, resulting in a CSI report including X+1 CRIs. In a second option, the UE may be configured to report a single CSI associated between the NCJT assumption and the single-TRP assumption (e.g., the best or highest CSI).

[0129]

[0137] If additional RRC signaling enables sharing of the CMR 310 between the NCJT assumption and the single-TRP assumption, each of the CMRs 310 (e.g., K1+K2=K sThe number of CMRs 310 in the first CMR group 305-a corresponds to a valid single-TRP assumption (e.g., including the CMRs 310 in the CMR pairs 315), and the UE is configured with M1 CMRs 310 from the first CMR group 305-a (where M1=K1 CMRs 310) and M2 CMRs 310 from the second CMR group 305-b (where M2=K2 CMRs 310) for the single-TRP assumption. Furthermore, if additional RRC signaling disables the sharing of CMRs 310 between the NCJT assumption and the single-TRP assumption, the UE may determine the number of CMRs 310 in the first CMR group 305-a (e.g., N1 CMRs 310) that appear in any of the CMR pairs 315 and the number of CMRs 310 in the second CMR group 305-b (e.g., N2 CMRs 310) that appear in any of the CMR pairs 315. In cases where CMRs 310 are not shared between CMR pairs 315 (e.g., not shared with respect to CMRs appearing in a CMR pair for NCJT CSI assumptions) (e.g., each CMR pair 315 includes a separate CMR as shown in the example CMR configuration 300), the number of CMRs 310 from each CMR group 305 in a CMR pair 315 (e.g., N1 and N2 for CMR groups 305-a and 305-b, respectively) may be the same as the number of CMR pairs 315 (e.g., N CMR pairs 315). In some other cases where CMRs 310 are shared between CMR pairs 315, the number of CMRs 310 from each CMR group 305 in a CMR pair 315 may be less than or equal to the number of CMR pairs 315. Based on determining the number of CMRs 310 in the CMR pair (e.g., N1 and N2 for CMR groups 305-a and 305-b, respectively), the UE may determine the number of valid single TRP hypotheses (e.g., CMRs not shared with the CMR pair).That is, the UE may be configured with M1 CMRs 310 from the first CMR group 305-a (where M1 = K1 - N1 CMRs 310, e.g., indicating the number of unshared CMRs in the first CMR group) for a single TRP assumption and M2 CMRs 310 from the second CMR group 305-b (where M2 = K2 - N2 CMRs 310, e.g., indicating the number of unshared CMRs in the second CMR group).

[0130]

[0138] In a second option, the number of CRI code points is C = M + M + N (e.g., as described with respect to Equation 3). For example, if two NCJT hypotheses corresponding to CMR pair 315-a (e.g., including CMRs 310-a and 310-d) and CMR pair 315-b (e.g., including CMRs 310-b and 310-e) are configured (e.g., N = 2), sharing is disabled, and a single TRP measurement hypothesis corresponds to CMR 310-c and CMR 310-f, the number of code points may be four, and thus CSI report 301 may include two bits (e.g., in CRI 330-a) to cover four code points (e.g., C = 2 + 1 + 1).

[0131]

[0139] In another example related to the first option, the number of CRI codepoints may depend on the value of X (e.g., the UE is configured to report X CSIs associated with a single TRP hypothesis). If X=0 (one CRI 330 is reported), then C=N (e.g., as described with respect to Equation 4). If X=1 (two CRIs 330 are reported), then C1=N and C2=M1+M2 (e.g., as described with respect to Equation 5). If X=2 (three CRIs 330 are reported), then C1=N, C2=M1, and C3=M2. In one example, if two NCJT hypotheses corresponding to CMR pair 315-a (e.g., including CMRs 310-a and 310-d) and CMR pair 315-b (e.g., including CMRs 310-b and 310-e) are configured (e.g., N=2), and thus N1=2, N2=2, M1=K1-N1=3-2=1, and M2=K2-N2=3-2=1, and sharing is disabled, indicating a single TRP measurement hypothesis corresponds to CMRs 310-c and 310-f, then if X=0 (one CRI 330), then C=2, and therefore the CSI report may include one bit to cover two possible code points. If X=1 (two CRIs), then C1=2 (1 bit), and C2=1+1=2 (2 bits), and thus the CSI report may include two CRIs 330 (e.g., two CRI fields), where the first field includes 1 bit and the second field includes 1 bit. If X=2 (three CRIs 330), then C1=2 (1 bit), C2=1 (0 bit, not reported as described with respect to Equation 1), and C3=1 (0 bit, not reported as described with respect to Equation 1), and thus the CSI report 301 may include three CRIs 330 (e.g., three CRI fields), where the first field includes 1 bit, the second field includes 0 bit, and the third field includes 0 bit (e.g., the second and third fields may be omitted from the CSI report 301). In other examples, the second field and the third field may include one or more bits and may be included in the CSI report 301.Note that other values ​​of N, M1, and M2 can be constructed and therefore result in a different number of code points in the above example.

[0132]

[0140] In another example related to the first option, if two NCJT hypotheses are configured (e.g., N=2) corresponding to CMR pair 315-a (e.g., including CMRs 310-a and 310-d) and another CMR pair 315 (e.g., including CMRs 310-a and 310-e), and therefore N1=1, N2=2, M1=K1-N1=3-1=2, and M2=K2-N2=3-2=1, sharing is disabled, and a single TRP measurement hypothesis corresponds to CMRs 310-b, 310-c, and 310-f, then X=0 (one CRI 330), and C=2, and therefore the CSI report may include one bit to cover two possible code points. If X = 1 (two CRIs), then C1 = 2 (1 bit) and C2 = 2 + 1 = 3 (2 bits), and thus the CSI report may include two CRIs 330 (e.g., two CRI fields), where the first field includes 1 bit and the second field includes 2 bits. If X = 2 (three CRIs 330), then C1 = 2 (1 bit), C2 = 2 (1 bit), and C3 = 1 (0 bit, not reported as described with respect to Equation 1), and thus the CSI report 301 may include three CRIs 330 (e.g., three CRI fields), where the first field includes 1 bit, the second field includes 2 bits, and the third field includes 0 bit (e.g., the third field may be omitted from the CSI report 301). In other examples, the third field may include one or more bits and may be included in the CSI report 301. Note that other values ​​of N, M1, and M2 can be constructed and therefore result in a different number of code points in the above example.

[0133]

[0141] In some cases, the base station may indicate sharing of CMRs 310 between a single TRP measurement assumption and an NCJT measurement assumption by configuring the same value of CMR ID for a single TRP CMR and NCJT CMR pair. In this example, the UE may determine that the first N CMRs 310 in each CMR group 305 are used only for NCJT, and the UE may select a CMR 310 for the single TRP assumption starting with the N+1 CMR 310 of the CMR group 305. Thus, the UE may determine M based on the value of N, where M=K−N and M=K−N. In a first option, the UE may be configured to report X CSIs associated with the single TRP assumption and one CSI associated with the NCJT assumption, where the configured value of X may be, for example, 0, 1, or 2, resulting in a CSI report including X+1 CRIs. In a second option, the UE may be configured to report a single CSI associated with the NCJT hypothesis and the single TRP hypothesis (eg, the best or highest CSI).

[0134]

[0142] If the UE is configured with M1 CMRs 310 from the first CMR group 305-a (where M1 = K1 - N CMRs 310 corresponding to the number of valid sTRP hypotheses in the first CMR group, e.g., the number of CMRs in the first CMR group minus the number of pairs) for a single TRP hypothesis and M2 CMRs 310 from the second CMR group 305-b (where M2 = K2 - N CMRs 310 corresponding to the number of valid sTRP hypotheses in the second CMR group, e.g., the number of CMRs in the second CMR group minus the number of pairs), in the second option, the number of CRI code points is C = M1 + M2 + N (e.g., as described with respect to Equation 3). For example, if two NCJT hypotheses are configured (e.g., N=2) corresponding to CMR pair 315-a (e.g., including CMRs 310-a and 310-d) and CMR pair 315-b (e.g., including CMRs 310-b and 310-e), and a single TRP measurement hypothesis corresponds to CMRs 310-c and 310-f, the number of code points may be four, and therefore, CSI report 301 may include two bits (e.g., in CRI 330-a) to cover four code points (e.g., C=2+1+1).

[0135]

[0143] In another example, if a UE is configured with M1 CMRs 310 (out of K1 CMRs) from a first CMR group 305-a and M2 CMRs 310 (out of K2 CMRs 310) from a second CMR group 305-b for a single TRP hypothesis, in the first option, the number of CRI code points may depend on the value of X (e.g., the UE is configured to report X CSIs associated with the single TRP hypothesis). If X=0 (one CRI 330 is reported), then C=N (e.g., as described with respect to Equation 4). If X=1 (two CRIs 330 are reported), then C1=N and C2=M1+M2 (e.g., as described with respect to Equation 5). If X=2 (three CRIs 330 are reported), then C1=N, C2=M1, and C3=M2. In one example, if two NCJT hypotheses corresponding to CMR pair 315-a and 315-b are configured (e.g., N=2) and additional RRC signaling indicates that a single TRP measurement hypothesis corresponds to CMRs 310-c and 310-f, then if X=0 (one CRI 330), then C=2, and thus the CSI report may include one bit to cover two possible codepoints. If X=1 (two CRIs), then C1=2 (one bit) and C2=1+1=2 (two bits), and thus the CSI report may include two CRIs 330 (e.g., two CRI fields), where the first field includes one bit and the second field includes one bit. If X=2 (three CRIs 330), then C1=2 (1 bit), C2=1 (0 bit, not reported as described with respect to Equation 1), and C3=1 (0 bit, not reported as described with respect to Equation 1), and thus the CSI report 301 may include three CRIs 330 (e.g., three CRI fields), where the first field includes 1 bit, the second field includes 0 bit, and the third field includes 0 bit (e.g., the second and third fields may be omitted from the CSI report 301). In other examples, the second and third fields may include one or more bits and may be included in the CSI report 301.Note that other values ​​of N, M1, and M2 can be constructed and therefore result in a different number of code points in the above example.

[0136]

[0144] FIG. 4 illustrates an example of a CMR configuration 400 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. In some cases, the CMR configuration 400 may be an example of a CMR configuration indicated to a UE by a base station (e.g., via control signaling) as described with reference to FIGS. 1-3. The CMR configuration 400 may include a CMR group 405-a and a CMR group 405-b. In some cases, the CMR group 405-a may be a set of CMRs 410 associated with a first TRP (e.g., associated with a base station). That is, the base station may transmit a reference signal (e.g., CSI-RS, CRS) via one of the CMRs 410 in the CMR group 405-a using the first TRP. Furthermore, the CMR group 405-b may be a set of CMRs 410 associated with a second TRP (e.g., associated with a base station). Here, the base station may transmit a reference signal via one of the CMRs 410 in the CMR group 405-b using the second TRP. In some cases, the base station may indicate the CMR group 405 to the UE via control signaling (eg, RRC signaling).

[0137]

[0145] The base station may indicate (e.g., by control signaling) a subset of CMRs 410 in the CMR group 405-a for the UE to monitor a single TRP CSI report associated with a first TRP, a subset of CMRs 410 in the CMR group 405-b for the UE to monitor a single TRP CSI report associated with a second TRP, and one or more CMR pairs 415-a for the UE to monitor joint TRP CSI reports.

[0146] To configure a first subset of CMRs 410 from CMR group 405-a and a second subset of CMRs 410 from CMR group 405-b, the base station first selects some of the CMRs 410 (e.g., K s In some cases, the CMR group 405-a includes a first number of CMRs 410 (e.g., K1 CMRs 410), and the CMR group 405-b includes a second number of CMRs 410 (e.g., K2 CMRs 410). Based on configuring the CMR group 405-a and the CMR group 405-b, the base station may indicate to the UE CMR pairs 415 for joint TRP CSI reporting. In one example, the base station may indicate the CMR pairs 415 by indicating (e.g., via control signaling) the number of CMR pairs 415 (e.g., N CMR pairs 415) that the UE will monitor for joint TRP CSI reporting.

[0139]

[0147] Based on configuring the CMR groups 405-a and 405-b and configuring the CMR pair 415, the base station may configure a first subset of CMRs 410 from the CMR group 405-a (e.g., to determine a single TRP CSI measurement associated with a first TRP) and a second subset of CMRs 410 from the CMR group 405-b (e.g., to determine a single TRP CSI measurement associated with a second TRP). The first subset of CMRs 410 from the first CMR group 405-a may include M1 CMRs 410, and the second subset of CMRs 410 from the second CMR group 405-b may include M2 ​​CMRs 410.

[0140]

[0148] In the example CMR configuration 400, the base station performs joint TRP CSI reporting and single TRP CSI reporting. The UE may configure a subset of CMRs 410 by indicating that sharing of the CMRs 410 between CSI reports is disabled. Here, the UE may determine that the subset includes CMRs 410 in each CMR group 405 that are distinct from the CMRs 410 in the CMR pairs 415. That is, the base station may transmit RRC signaling to disable sharing of the CMRs 410 (e.g., between the NCJT assumption and the single-TRP assumption). The UE may then determine the number of CMRs 410 in the first CMR group 405-a that appear in any of several CMR pairs 415 (e.g., N1 CMRs 410) and the number of CMRs 410 in the second CMR group 405-b that appear in any of several CMR pairs 415 (e.g., N2 CMRs 410). Here, the CMRs 410 are shared between the CMR pairs 415, and thus the number of CMRs 410 from the first CMR group 405-a in the CMR pairs 415 is less than the number of CMR pairs 415. That is, the UE may determine that a first subset of CMRs (e.g., associated with the first TRP and including the CMRs 410 from the first CMR group 405-a) includes CMRs 410-b and 410-c based on the CMRs 410-b and 410-c being distinct from the CMR 410-a in the CMR pair 415. Further, the UE may determine that a second subset of CMRs 410 (e.g., associated with a second TRP and including CMRs 410 from a second CMR group 405-b) includes CMR 410-f based on CMR 410-f being distinct from CMRs 410 in CMR group 405-f associated with CMR pair 415 (e.g., CMR 410-d and CMR 410-e).

[0141]

[0149] 5 illustrates an example process flow 500 for supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. In some examples, the process flow 500 may implement aspects of FIGS. 1-4. For example, the process flow 500 may include a base station 505 and a UE 515 (e.g., associated with a first TRP and a second TRP), which may be examples of the base station and UE described with reference to FIGS. 1-4.

[0142]

[0150] At 510, the base station 505 may transmit control signaling to the UE 515. That is, the UE 515 may receive control signaling indicating a first subset of CMRs in a first CMR group for single-TRP channel measurements associated with a first TRP for joint TRP channel measurements, a second subset of CMRs in a second CMR group for single-TRP channel measurements associated with a second TRP, and one or more CMR pairs including CMRs from each of the first CMR group and the second CMR group.

[0143]

[0151] At 520, the UE 515 may monitor CMRs based on the control signaling received from the base station 505 at 510. That is, the UE 515 may monitor a first subset of CMRs, a second subset of CMRs, and one or more CMR pairs to generate a set of measurements.

[0144]

[0152] At 525, the UE 515 may transmit a CSI report to the base station 505. That is, the UE 515 may transmit a CSI report including a number of bits indicating one or more CRIs associated with at least one of the sets of measurements, where the number of bits is based on the number of CMR pairs. In some examples, the number of bits may be based on the number of one or more CRIs, a first number of CMRs in the first subset, a second number of CMRs in the second subset, and the number of CMR pairs. Furthermore, the number of CRIs in the CSI report associated with one of the first TRP or the second TRP may be 0, 1, or 2.

[0145]

[0153] In some cases, the number of bits in the CSI report may indicate a single CRI, where the number of bits is based on the number of CMR pairs. In some other cases, the number of bits in the CSI report may indicate a set of CRIs, where the number of bits corresponds to a first number of bits in a first CRI of the set of CRIs based on the number of CMR pairs and a second number of bits in a second CRI of the set of CRIs based on the sum of the first number of CMRs in the first subset and the second number of CMRs in the second subset.

[0146]

[0154] In some other cases, the number of bits in the CSI report may indicate a set of CRIs, where the number of bits corresponds to a first number of bits in a first CRI of the set of CRIs based on the number of CMR pairs, a second number of bits in a second CRI of the set of CRIs based on the first number of CMRs in the first subset, and a third number of bits in a third CRI of the set of CRIs based on the second number of CMRs in the second subset. In some other cases, the number of bits in the CSI report may indicate a single CRI, where the number of bits is based on the sum of the first number of CMRs in the first subset, the second number of CMRs in the second subset, and the number of CMR pairs.

[0147]

[0155] In some examples, the first subset may include a first number of unshared CMRs in a first CMR group, and the second subset may include a second number of unshared CMRs in a second CMR group, where the unshared CMRs are separate from the CMRs in one or more CMR pairs. Here, the number of bits in the CSI report may indicate a set of CRIs based on control signaling indicating that CMR sharing is disabled between single-TRP channel measurements and joint-TRP channel measurements, where the number of bits corresponds to a first number of bits in the first CRI of the set of CRIs based on the number of CMR pairs and a second number of bits in the second CRI of the set of CRIs based on the first number of unshared CMRs in the first subset and the second number of unshared CMRs in the second subset.

[0148]

[0156] In some examples, the first subset may include a first number of unshared CMRs in the first CMR group, and the second subset may include a second number of unshared CMRs in the second CMR group, where the unshared CMRs are separate from the CMRs in one or more CMR pairs. Here, the number of bits in the CSI report may indicate a set of CRIs based on control signaling indicating that CMR sharing is disabled between single-TRP channel measurements and joint-TRP channel measurements, where the number of bits corresponds to a first number of bits in a first CRI of the set of CRIs based on the number of CMR pairs, a second number of bits in a second CRI of the set of CRIs based on the first number of unshared CMRs in the first subset, and a third number of bits in a third CRI of the set of CRIs based on the second number of unshared CMRs in the second subset.

[0149]

[0157] In some examples, the first subset may include a first number of unshared CMRs in the first CMR group, and the second subset may include a second number of unshared CMRs in the second CMR group, where the unshared CMRs are separate from the CMRs in one or more CMR pairs. Here, the number of bits in the CSI report may indicate a single CRI based on control signaling indicating that CMR sharing is disabled between single-TRP channel measurements and joint-TRP channel measurements, where the number of bits is based on the sum of the first number of unshared CMRs in the first subset, the second number of unshared CMRs in the second subset, and the number of CMR pairs.

[0150]

[0158] In some cases, the number of bits in the CSI report may indicate a set of CRIs, where the number of bits corresponds to a first number of bits in a first CRI of the set of CRIs based on the number of CMR pairs and a second number of bits in a second CRI of the set of CRIs based on the sum of a first number of CMRs in a first subset for single-TRP channel measurements and a second number of CMRs in a second subset for single-TRP channel measurements. Further, the first number of CMRs may be based on the difference between the third number of CMRs in the first CMR group and the number of CMR pairs. Further, the second number of CMRs may be based on the difference between the fourth number of CMRs in the second CMR group and the number of CMR pairs.

[0151]

[0159] In some cases, the number of bits in the CSI report indicates a set of CRIs, where the number of bits corresponds to a first number of bits in a first CRI of the set of CRIs based on the number of CMR pairs, a second number of bits in a second CRI of the set of CRIs based on the first number of CMRs in the first subset for single TRP channel measurements, and a third number of bits in a third CRI of the set of CRIs based on the second number of CMRs in the second subset for single TRP channel measurements, where the first number of CMRs is based on the difference between the third number of CMRs and the number of CMR pairs in the first CMR group, and where the second number of CMRs is based on the difference between the fourth number of CMRs and the number of CMR pairs in the second CMR group.

[0152]

[0160] In some examples, the number of bits in a CSI report may indicate a single CRI, where the number of bits is based on the sum of a first number of CMRs in a first subset for single TRP channel measurement, a second number of CMRs in a second subset for single TRP channel measurement, and the number of CMR pairs, where the first number of CMRs may be based on the difference between the third number of CMRs and the number of CMR pairs in the first CMR group, and the second number of CMRs may be based on the difference between the fourth number of CMRs and the number of CMR pairs in the second CMR group.

[0153]

[0161] 6 illustrates an example of a wireless communication system 600 supporting CSI reporting using single and joint TRP measurements in accordance with aspects of the present disclosure. In some examples, the wireless communication system 600 may implement aspects of the wireless communication system 100. For example, the wireless communication system 600 may include a base station and a UE 615, which may be examples of the base station 105 and the UE 115, respectively, described with reference to FIG. 1.

[0154]

[0162] The UE 615 may be in communication with the base station 605. For example, the UE 615 and the base station 605 may exchange messages (e.g., CSI report 625, CSI-RS 620) and signaling (e.g., control signaling 610). In some cases, the base station 605 may include or be associated with two or more TRPs. For example, the base station 605 may rely on multiple TRPs (e.g., two) for communication with the UE 615. The base station 605 may send control signaling 610 to the UE 615, which may configure the UE 615 for subsequent communication with the base station 605. For example, the control signaling 610 may indicate to the UE 615 CMRs associated with two or more of the TRPs for the UE 615 to monitor to generate the CSI report 625. That is, the base station 605 may transmit control signaling 610 indicating to the UE 615 to monitor a first subset of CMRs (e.g., associated with a first TRP of the base station 605), a second subset of CMRs (e.g., associated with a second TRP of the base station 605), and one or more pairs of CMRs (e.g., including a first CMR associated with the first TRP and a second CMR associated with the second TRP). That is, the base station 605 may indicate to the UE 615 to monitor N CMR pairs. Thus, the UE 615 may generate a CSI report 625 based on monitoring CMRs associated with a single TRP (e.g., CMRs in the first and second subsets) and based on monitoring CMRs associated with a joint TRP (e.g., a CMR pair).

[0155]

[0163] The control signaling 610 may further indicate a configuration for the CSI report 625. In some cases, the control signaling 610 may indicate the amount of CSI (e.g., joint TRP CSI 630, single TRP CSI 635). In one example, the control signaling 610 may indicate to the UE 615 to include a single CSI in the CSI report 625. Here, the UE 615 may transmit a CSI report 625 that includes the joint TRP CSI 630 (e.g., does not include the single TRP CSI 635). When the UE 615 transmits a single joint TRP CSI 630, the UE 615 may include CSI related to one of the pair of CMRs that has a higher measured signal quality (e.g., that the UE 615 has indicated to monitor) than the remaining pair of CMRs. In another case, the control signaling 610 may indicate to the UE 615 to include two or more CSIs in the CSI report 625. For example, the control signaling 610 may indicate to the UE 615 that it includes one joint TRP CSI 630 and two single TRP CSIs 635, where the joint TRP CSI 630 may correspond to the CMR pair with the highest measured signal quality for each of the CMR pairs monitored by the UE 615. Additionally, the single TRP CSI 635 may include a CSI associated with a single CMR from one of the CMR pairs monitored by the UE 615.

[0156]

[0164] The control signaling 610 may further indicate to the UE 615 the sharing of PMI and RI between the joint TRP CSI 630 and the single TRP CSI 635. For example, the base station 605 may enable (or otherwise disable) the sharing of PMI and RI between the joint TRP CSI 630 and the single TRP CSI 635 via higher layer configuration. Additionally or alternatively, the base station 605 may dynamically indicate that the sharing of PMI and RI is enabled (or otherwise disabled).

[0157]

[0165] For Case 1, the base station 605 may configure the UE to report a joint TRP CSI 630 (e.g., an NCJT CSI) and X single TRP CSIs 635, and may further set X to 0. In this Case 1 (e.g., when the base station 605 configures the UE 615 to include a single CSI, the joint TRP CSI 630, in the CSI report 625), when sharing PMI and RI between the joint TRP CSI 630 and the single TRP CSI 635, the joint TRP CSI 630 is (e.g., the joint TRP CSI, The joint TRP CSI 630 may include two RIs (e.g., corresponding to one of the CMRs in the CMR pair associated with the joint TRP CSI 630), two PMIs (e.g., each corresponding to one of the CMRs in the CMR pair associated with the joint TRP CSI 630), and a CQI associated with the CMR pair. The joint TRP CSI 630 may further include a CQI associated with each CMR in the CMR pair (and, e.g., a CQI associated with a single TRP CSI). That is, because the first PMI and RI of the joint TRP CSI 630 are shared with the first CMR (e.g., rather than the second CMR of the CMR pair), the UE 615 may use the first of the two RIs in the joint TRP CSI 630 (e.g., corresponding to the first CMR) and the first of the two PMIs in the joint TRP CSI 630 (e.g., corresponding to the first CMR) to calculate a first CQI associated with the first CMR of the CMR pair (e.g., associated with the first TRP). Additionally, the UE 615 may use the second of the two RIs in the joint TRP CSI 630 (e.g., corresponding to the second CMR) and the second of the two PMIs in the joint TRP CSI 630 (e.g., corresponding to the second CMR) to calculate a second CQI associated with the second CMR of the CMR pair (e.g., associated with the second TRP).

[0158]

[0166] For Case 2, the base station 605 may configure the UE to report a joint TRP CSI 630 (e.g., an NCJT CSI) and X single TRP CSIs 635, and may further set X to 2. In this Case 2 (e.g., when the base station 605 configures the UE 615 to include a single CSI in the CSI report 625, the joint TRP CSI 630, and both single TRP CSIs 635), when the base station 605 enables sharing of PMI and RI between the joint TRP CSI 630 and the single TRP CSI 635, the joint TRP CSI 630 may include two RIs (e.g., each corresponding to one of the CMRs in the CMR pair associated with the joint TRP CSI 630), two PMIs (e.g., each corresponding to one of the CMRs in the CMR pair associated with the joint TRP CSI 630), and a CQI associated with the CMR pair. In one example where each of the single TRP CSIs 635 is associated with one of the CMRs from a CMR pair (e.g., corresponding to a joint TRP CSI 630), the single TRP CSI 635-a associated with the first CMR of the CMR pair may include a first RI of two RIs included in the joint TRP CSI 630 (e.g., corresponding to the first CMR) and a CQI associated with the first CMR. The CSI635-b may include a second RI of two RIs included in the joint TRP CSI630 (e.g., corresponding to a second CMR) and a CQI associated with the second CMR. Here, the single TRP CSI635 may not include a PMI because each of the CQIs in the single TRP CSI635 is calculated assuming the PMI and RI as reported in the joint TRP CSI630 (e.g., as reported in an NCJT CSI). In other examples where each of the single TRP CSI635 is associated with a CMR that is separate from the CMR pair associated with the joint TRP CSI630, the single TRP CSI635 may each include the RI, PMI, and CQI associated with the corresponding CMR.

[0159]

[0167] The control signaling 610 may further indicate to the UE 615 a configuration for calculating a CQI associated with one CMR (e.g., for a single TRP CSI 635) of a CMR pair (e.g., associated with the joint TRP CSI 630) using the same PMI and RI as used for the joint TRP CSI 630. In one example, the base station 605 may send control signaling 610 indicating a configuration to the UE 615 to ignore the other CMR (e.g., of the pair) when calculating the CQI associated with one CMR of the pair. That is, the UE 615 may ignore (e.g., not consider) the other CMR of the CMR pair when calculating the CQI associated with one CMR of the pair. In another example, the base station 605 may send control signaling 610 indicating a configuration to the UE 615 to use the other CMR as an interference measurement when calculating the CQI associated with one CMR of the pair. That is, the UE 615 may use the other CMR as a non-zero power interference management resource (NZP-IMR) for calculating a CQI associated with one CMR. In some cases, the configuration may indicate to the UE 615 not to assume the other PMI and RI for interference measurement (e.g., associated with the other CMR from the CMR pair) when calculating a CQI associated with one CMR from the pair. Here, the UE 615 may assume that each port of the other CMR is one interference layer. In other cases, the configuration may indicate to the UE 615 to apply the other PMI and RI (e.g., associated with the other CMR from the CMR pair) when calculating a CQI associated with one CMR from the pair. Here, the UE 615 may apply the other PMI and RI to the second CMR to determine interference. For example, the UE 615 may calculate a first CQI associated with a first CMR from the pair based on the interference associated with the second CMR. Additionally, the UE 615 may calculate a second CQI associated with a second CMR from the pair based on the interference associated with the first CMR (e.g., the roles of the first and second CMR, PMI, and RI may be reversed).

[0160]

[0168] Before generating the CSI report 625, the UE 615 may determine the number of occupied CPU, active CSI-RS resources, and active occupied CSI-RS ports associated with the configured CSI report 625. That is, the UE 615 may support a threshold number of occupied CPU, active CSI-RS resources, and active occupied CSI-RS ports for CSI (e.g., based on the capabilities of the UE 615). Furthermore, the UE 615 may refrain from updating the remaining CSI if the total number of active CSI-RS resources exceeds a defined number of active CSI-RS resources supported by the UE 615 or if the total number of active CSI-RS port occupancies associated with the CSI report exceeds a defined number of active CSI-RS port occupancies supported by the UE 615. Thus, the UE 615 may determine the number of occupied CPUs, active CSI-RS resources, and active occupied CSI-RS ports associated with the CSI report 625 configured before generating the CSI report (e.g., to ensure that the number of occupied CPUs, active CSI-RS resources, and active occupied CSI-RS ports associated with the CSI report 625 does not exceed a defined number associated with the capabilities of the UE 615).

[0161]

[0169] When the UE 615 is configured with sharing of PMI and RI between the NCJT CSI (e.g., joint TRP CSI 630) and a single TRP CSI 635, and the UE 615 is configured to include a single CSI in the CSI report 625 (e.g., the joint TRP CSI 630 associated with a CMR pair and including a CQI for each of the individual CMRs in the CMR pair), the UE 615 may determine the occupied CPU, active CSI-RS resources, and active and occupied CSI-RS ports associated with the configured CSI report 625 based on the number of CMR pairs the UE 615 is configured to monitor (e.g., N CMR pairs configured by the control signaling 610) and the number of ports each CMR has (e.g., P ports). In one example, as shown in Equation 8, the UE 615 may determine the occupied CPU (CPU Occupied ) and active CSI-RS resources (R Active ) and the active and occupied CSI-RS ports (P Active ) and the number of CQIs. That is, UE 615 may determine two additional CQIs and report the CSI for one of the hypotheses for each NCJT hypothesis.

[0162]

number

[0163]

[0170] In another example, as shown below in Equation 9, the UE 615 may determine the occupied CPU (CPU ) associated with the CSI report 625 based on selecting one NCJT CSI hypothesis (e.g., from N CMR pairs). Occupied ) and active CSI-RS resources (R Active ) and the active and occupied CSI-RS ports (P Active ), and may count the individual CMRs of the selected CMR pairs (e.g., instead of also counting the individual CMRs of the unselected CMR pairs).

[0164]

number

[0165]

[0171] In another example, as shown below in Equation 10, the UE 615 may determine the occupied CPU (CPU Occupied ) and active CSI-RS resources (R Active ) and the active and occupied CSI-RS ports (P Active ) and the number of

[0166]

number

[0167]

[0172] In another example, as shown below in Equation 11, the UE 615 may calculate the occupied CPU (CPU Occupied ) and active CSI-RS resources (R Active ) and the active and occupied CSI-RS ports (P Active ) and the number of TRPs. The UE 615 may further determine the number of TRPs based on a threshold for the calculation of additional single TRP CQIs (e.g., single TRPs). The computational complexity of two additional CQIs (related to the CQI) may be determined.

[0168]

number

[0169]

[0173] In some cases, the UE 615 may determine that the number of occupied CPUs associated with the CSI report 625 is the same as when the PMI or RI is not shared (e.g., as shown with respect to Equation 11). Here, the UE 615 may determine an increased number of active resources or ports (e.g., compared to Equation 11). That is, although CPU may be involved in the complexity of the PMI calculation, in some cases where the UE 615 calculates an additional single TRP CQI, the UE 615 may not calculate another PMI (e.g., due to PMI sharing).

[0170]

[0174] FIG. 7A illustrates an example of a CMR configuration 700 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. Additionally, FIGS. 7B and 7C illustrate an example CSI report 701 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. In some cases, the CMR configuration 700 may be an example of a CMR configuration indicated to a UE by a base station (e.g., via control signaling) as described with reference to FIGS. 1, 2, and 6. Additionally, the CSI report 701 may be an example of a CSI report transmitted by a UE to a base station as described with reference to FIGS. 1, 2, and 6. In some cases, the UE may be configured with the CMR configuration 700, may monitor resources for CSI-RS based on the CMR configuration 700, and may transmit the CSI report 701 (e.g., to a base station) based on monitoring resources associated with the CMR configuration 700.

[0171]

[0175] 7A shows a CMR configuration 700 including a CMR group 705-a and a CMR group 705-b. In some cases, the CMR group 705-a may be a set of CMRs 710 associated with a first TRP (e.g., associated with a base station). That is, the base station may transmit a reference signal (e.g., CSI-RS, CRS) via one of the CMRs 710 in the CMR group 705-a using the first TRP. Furthermore, the CMR group 705-b may be a set of CMRs 710 associated with a second TRP (e.g., associated with a base station). Here, the base station may transmit a reference signal via one of the CMRs 710 in the CMR group 705-b using the second TRP. In some cases, the base station may indicate the CMR group 705 to the UE via control signaling (e.g., RRC signaling).

[0172]

[0176] The base station may indicate (e.g., by control signaling) a subset of CMRs 710 in CMR group 705-a for the UE to monitor a single TRP CSI report associated with a first TRP, a subset of CMRs 710 in CMR group 705-b for the UE to monitor a single TRP CSI report associated with a second TRP, and one or more CMR pairs 715-a for the UE to monitor joint TRP CSI reports. The base station may further indicate to the UE to share PMI and RI between the CMR pair 715 and each individual CMR 710 in the CMR pair 715. For example, the UE may calculate a first PMI and RI associated with CMR 710-a and a second PMI and RI associated with CMR 710-d to calculate CSI for CMR pair 715-a. Here, the UE may determine a CQI associated with CMR 710-a using a first PMI and RI (e.g., calculated for the CSI associated with CMR pair 715-a) and a CQI associated with CMR 710-d using a second PMI and RI.

[0173]

[0177] 7B shows an example CSI report 701-a. The UE may generate the CSI report 701 in response to monitoring the CMR 710 according to a CMR configuration 700 configured by the base station.

[0174]

[0178] In Case 1, if the base station configures the UE to report a single NCJT CSI (e.g., a joint TRP CSI 730-a) and X single TRP CSIs 735 and sets X to 0 (e.g., the UE is configured to report a single joint TRP CSI 730-a), the UE may include the joint TRP CSI 730-a, CQI 740-b, and CQI 740-c in the CSI report 701-a. Here, the UE may determine RI 725-a and PMI 745-a (e.g., associated with a first TRP) and RI 725-b and PMI 745-b (e.g., associated with a second TRP) for the NCJT CSI (e.g., the joint TRP CSI 730-a). The UE may then determine the CQI 740-a associated with the NCJT CSI using the RI 725-a and PMI 745-a. Further, the UE may determine a CQI 740-b (eg, associated with a second TRP) using the RI 725-b and the PMI 745-b.

[0179] In one example of Case 1, a joint TRP CSI 730-a may be associated with a CMR pair 715-b (e.g., including a CMR 710-b associated with a first TRP and a CMR 710-e associated with a second TRP). Here, the UE may determine an RI 725-a and a PMI 745-a based on the CMR 710-b and determine an RI 725-b and a PMI 745-b based on the CMR 710-e. Further, the UE may determine a CQI 740-a associated with the CMR pair 715-b using the RIs 725-a and 725-b and the PMIs 745-a and 745-b. The UE may further determine a CQI 740-b associated with CMR 710-b using RI 725-a and PMI 745-a (e.g., based on sharing being enabled), and may determine a CQI 740-c associated with CMR 710-e using RI 725-b and PMI 745-b. Here, the UE may include CRI 720-a, RI 725, and CQI 740-a (e.g., indicating CMR pair 715-b) in Part 1 of CSI report 701-a, and the UE may include PMI 745 in CSI Part 2 of CSI report 701-a. Furthermore, the UE may include CQI 740-b and CQI 740-c in CSI report 701-a (e.g., as part of either CSI Part 1 or CSI Part 2). In some examples, the PMI may be reported in CSI Part 2 (whether it belongs to the NCJT or the sTRP CSI). CSI Part 1 may include a field used by the base station to decode CSI Part 2. The CRI, RI, and CQI are in CSI Part 1, while the PMI and LI (layer indicator) are in CSI Part 2, and CSI Part 1 and CSI Part 2 may be coded separately (e.g., may not be jointly coded). CQI 740-b and CQI 740-c, when present in CSI Part 1, are jointly coded with CRI 720-a, RI 725, and CQI 740-a. CQI 740-b and CQI 740-c, when present in CSI Part 1, are jointly coded with PMI 745.

[0176]

[0180] In Case 2, if a base station configures a UE to report a single NCJT CSI (e.g., a joint TRP CSI 730-a) and X single TRP CSIs 735, where X is set to 2, and the base station is configured with sharing of PMI 745 and RI 725 (e.g., between the NCJT CSI and the single TRP CSI 735), the UE may include the joint TRP CSI 730-a, the single TRP CSI 735-a, and the single TRP CSI 735-b in the CSI report 701-a. CSI report 701-a may correspond to CSI report 701-a if the CMR pair 715 associated with the joint TRP CSI 730-a includes a first CMR 710 associated with the first single TRP CSI 735-a and a second CMR 710 associated with the second single TRP CSI 735-b. That is, in the example CSI report 701-a, the selected CMR 710 of the first sTRP CSI (e.g., indicated by CRI 720-b in single TRP CSI 735-a) and the selected CMR 710 of the second sTRP CSI (e.g., indicated by CRI 720-c in single TRP CSI 735-b) are the same as the selected CMR pair 715 (e.g., indicated by CRI 720-a in joint TRP CSI 730-a). In this example, the UE may omit CSI part 2 (e.g., at least a portion of CSI part 2 including PMI) from the single TRP CSI 735. Here, the UE may include an RI 725-a for the first single TRP CSI 735-a that is the same as the first RI 725-a of the joint TRP CSI 730-a. In some cases, the UE may not include LIs in the single TRP CSI 735 (and may include them in the joint TRP CSI 730-a). Additionally or alternatively, the UE may include the same LI value as reported in the joint TRP CSI 730-a in each of the single TRP CSIs 735. Furthermore, the UE may include an RI 725-b for the second single TRP CSI 735-b that is the same as the second RI 725-b of the joint TRP CSI 730-a.In some cases, CSI part 1 of CSI report 701-a may be a constant and not depend on the value of CRI720, so that the UE may report RI725 in a single TRP CSI735 (e.g., instead of omitting RI725 from the single TRP CSI735).

[0177]

[0181] 7C shows an example CSI report 701-b. The UE may generate the CSI report 701 in response to monitoring the CMR 710 according to a CMR configuration 700 configured by the base station. The CSI report 701-b may be an example CSI report 701-b related to Case 2, where the base station configures the UE to report a single NCJT CSI (e.g., a joint TRP CSI 730-b) and X single TRP CSIs 735, where X is set to 2, and the base station is configured with sharing of PMI 745 and RI 725 (e.g., between the NCJT CSI and the single TRP CSI 735). Thus, the CSI report 701-b may include the joint TRP CSI 730-b, the single TRP CSI 735-c, and the single TRP CSI 735-d in the CSI report 701-b.

[0178]

[0182] If the CMR pair 715 associated with the joint TRP CSI730-a includes a first CMR 710 distinct from the CMR 710 associated with the first single TRP CSI735-c and a second CMR 710 distinct from the CMR 710 associated with the second single TRP CSI735-d, the CSI report 701-b may correspond to the CSI report 701-a. For example, the joint TRP CSI730-b may correspond to the CMR pair 715-a, the single TRP CSI735-c may be associated with the CMR 710-c, and the single TRP CSI735-d may correspond to the CMR 710-f. Here, the PMI 745 and the RI 725 may not be shared between the NCJT CSI (e.g., the joint TRP CSI730-b) and the single TRP CSI735. Thus, each of the single TRPs CSI735 contains PMI745 (as PMI745 is distinct from PMI745- and 745-d within the joint TRP CSI730-b).

[0179]

[0183] 8 illustrates an example process flow 800 for supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. For example, process flow 800 may include a base station 805 and a UE 815 (e.g., associated with a first TRP and a second TRP), which may be examples of the base station and UE described with reference to FIGS. 1-7.

[0180]

[0184] At 810, the UE 815 may optionally transmit signaling to the base station 805 indicating a defined (e.g., threshold) number of CPUs supported by the UE 815, a defined number of active CSI-RS resources supported by the UE 815, and a defined number of active CSI-RS ports supported by the UE 815.

[0181]

[0185] At 815, the base station 805 may transmit control signaling to the UE 815. That is, the UE 815 may receive control signaling indicating a pair of CMRs and that the first PMI, the second PMI, the first RI, and the second RI of the joint TRP CSI calculated for the pair of CMRs are to be shared to generate a respective CQI for each CMR of the pair of CMRs. Further, the base station 805 may transmit second control signaling indicating a configuration for calculating the second CQI and the third CQI.

[0182]

[0186] At 820, the UE 815 may monitor the CMR to generate a joint TRP CSI including the first PMI, the second PMI, the first RI, the second RI, and the first CQI.

[0183]

[0187] At 830, the UE 815 may measure the first CMR independently from the second CMR to generate a second CQI according to a configuration (e.g., indicated by the second control signaling) and may measure the second CMR independently from the first CMR to generate a third CQI according to the configuration. Additionally or alternatively, the UE 815 may measure the first CMR and a first interfering signal received via the second CMR to generate the second CQI according to the configuration and may measure the second CMR and a second interfering signal received via the first CMR to generate the third CQI according to the configuration. Here, the UE 815 may apply a second PMI and a second RI to the first signal received via the second CMR to measure an interference level caused by the first interfering signal. Furthermore, the UE 815 may apply a first PMI and a first RI to the second signal received via the first CMR to measure an interference level caused by the second interfering signal.

[0184]

[0188] At 835, the UE 815 may transmit a CSI report to the base station 805 including the joint TRP CSI, a second CQI of a first CMR of the CMR pair calculated using the first PMI and the first RI, and a third CQI of a second CMR of the CMR pair calculated using the second PMI and the second RI. In some cases, the UE 815 may transmit the CSI report to the base station 805 using a number of active CSI-RS resources associated with the CSI report that is less than or equal to the defined number of active CSI-RS resources supported by the UE and a number of active CSI-RS ports associated with the CSI report that is less than or equal to the defined number of active CSI-RS ports supported by the UE 815 based on the number of CPUs associated with the CSI report being less than or equal to the defined number of CPUs supported by the UE 815. The UE 815 may determine the number of CPUs, active CSI-RS resources, and active CSI-RS ports associated with the CSI report based on one of Equations 8 to 11.

[0185]

[0189] 9 illustrates an example of a CSI scheme 900 that supports CSI reporting using single and joint TRP measurements in accordance with an embodiment of the present disclosure. In some cases, a UE and a base station described herein may utilize one or more aspects of the CSI scheme 900.

[0186]

[0190] The CSI scheme may include a CSI reporting configuration 905 that the base station may indicate to the UE via control signaling. The CSI reporting configuration 905 may indicate an NZP CMR resource set 910, a CSI-IM resource set 915, and an NZP IMR resource set 920. In some cases, the framework for the CSI reporting configuration 905 may include a link to one resource configuration (e.g., CMR), two resource configurations (e.g., CMR and CSI-IM or NZP-IMR), or three resource configurations (e.g., CMR, CSI-IM, and NZP-IMR). Here, each resource set (e.g., NZP CMR resource set 910, CSI-IM resource set 915, NZP IMR resource set 920) may have one active resource set. For example, the NZP CMR resource set 910 may include the active NZP CMR resource set N 910-a. Additionally, the CSI-IM resource sets 915 may include an active CSI-IM resource set M 915-a. Additionally, the NZP IMR resource sets 920 may include an active NZP IMR resource set S 920-a.

[0187]

[0191] The UE may evaluate the CSI corresponding to the NZP CMR resource set N 910-a. The UE may then select one CMR resource from the NZP CMR resource set N 910-a (e.g., NZP CMR resource N1 925-a, NZP CMR resource N2 925-b). In some cases, the UE may further select a CSI-IM resource 930 (e.g., CSI-IM resource M1 930-a, CSI-IM resource M2 930-b). Additionally or alternatively, the UE may select an NZP IMR resource 935 (e.g., NZP IMR resource S1 935-a, NZP IMR resource S2 935-b). In some cases, each CMR resource may be collectively associated with all NZP IMR resources 935. The UE may report the CRI as part of the CSI feedback. That is, the base station may rely on the CRI to determine the NZP CMR resource 925 associated with the CSI report.

[0192] 10 shows a block diagram 1000 of a device 1005 supporting CSI reporting using single and joint TRP measurements according to an embodiment of the present disclosure. The device 1005 may be an example of an embodiment of a UE 115 described herein. The device 1005 may include a receiver 1010, a transmitter 1015, and a communications manager 1020. The device 1005 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0189]

[0193] The receiver 1010 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to CSI reporting with single and joint TRP measurements). The information may be passed on to other components of the device 1005. The receiver 1010 may use a single antenna or a set of multiple antennas.

[0190]

For example, the transmitter 1015 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to CSI reporting using single and joint TRP measurements). In some examples, the transmitter 1015 may be co-located with the receiver 1010 in a transceiver module. The transmitter 1015 may utilize a single antenna or a set of multiple antennas.

[0192]

[0196] In some examples, the communications manager 1020, the receiver 1010, the transmitter 1015, or various combinations or components thereof, may be implemented in hardware (e.g., in communications management circuitry). The hardware may include a processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting a means for performing the functions described in this disclosure. In some examples, the processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing, by the processor, instructions stored in the memory).

[0193]

[0197] Additionally or alternatively, in some examples, the communications manager 1020, the receiver 1010, the transmitter 1015, or various combinations or components thereof, may be implemented in code executed by a processor (e.g., as communications management software or firmware). When implemented in code executed by a processor, the functionality of the communications manager 1020, the receiver 1010, the transmitter 1015, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a central processing unit, an ASIC, an FPGA, or any combination thereof or other programmable logic device (e.g., configured as or otherwise supporting a means for performing the functions described in this disclosure).

[0194]

[0198] In some examples, the communications manager 1020 may be configured to use or otherwise cooperate with the receiver 1010, the transmitter 1015, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communications manager 1020 may receive information from the receiver 1010, send information to the transmitter 1015, or be integrated in combination with the receiver 1010, the transmitter 1015, or both to receive information, transmit information, or perform various other operations described herein.

[0195]

[0199] The communications manager 1020 may support wireless communications in a UE according to examples disclosed herein. For example, the communications manager 1020 may be configured with or otherwise support a means for receiving control signaling indicating a first subset of CMRs in a first CMR group for single-TRP channel measurements associated with a first TRP for joint TRP channel measurements, a second subset of CMRs in a second CMR group for single-TRP channel measurements associated with a second TRP, and one or more CMR pairs including CMRs from each of the first and second CMR groups. The communications manager 1020 may be configured with or otherwise support a means for monitoring the first subset of CMRs, the second subset of CMRs, and one or more CMR pairs to generate a set of measurements. The communications manager 1020 may be configured with or otherwise support a means for transmitting a CSI report that includes a number of bits indicating one or more channel resource indicators associated with at least one of the sets of measurements, where the number of bits is based on the number of CMR pairs.

[0196]

[0200] Additionally or alternatively, communications manager 1020 may support wireless communications in a UE according to examples disclosed herein. For example, communications manager 1020 may be configured with or otherwise support a means for receiving control signaling indicating a pair of CMRs and that a first PMI, a second PMI, a first RI, and a second RI of a joint TRP CSI calculated for the pair of CMRs are to be shared to generate a respective CQI for each CMR of the pair of CMRs. Communications manager 1020 may be configured with or otherwise support a means for monitoring the pair of CMRs to generate a joint TRP CSI including the first PMI, the second PMI, the first RI, the second RI, and the first CQI. The communications manager 1020 may be configured with or otherwise support a means for transmitting a CSI report including the joint TRP CSI, a second CQI for a first CMR of the pair of CMRs calculated using the first PMI and the first RI, and a third CQI for a second CMR of the pair of CMRs calculated using the second PMI and the second RI.

[0197]

[0201] By including or configuring a communications manager 1020 according to the examples described herein, the device 1005 (e.g., a processor controlling or otherwise coupled to the receiver 1010, the transmitter 1015, the communications manager 1020, or a combination thereof) may support techniques for reduced processing and more efficient utilization of communications resources.

[0198]

[0208] FIG. 12 shows a block diagram 1200 of a communications manager 1220 supporting CSI reporting using single and joint TRP measurements according to an aspect of the present disclosure. The communications manager 1220 may be an example of an aspect of the communications manager 1020, the communications manager 1120, or both described herein. The communications manager 1220, or various components thereof, may be an example of a means for implementing various aspects of CSI reporting using single and joint TRP measurements described herein. For example, the communications manager 1220 may include a control signaling receiver 1225, a CMR monitoring component 1230, a CSI report transmitter 1235, a UE support signaling component 1240, a CMR measurement component 1245, or any combination thereof. Each of these components may communicate with one another directly or indirectly (e.g., via one or more buses).

[0208]

[0212] In some examples, to support transmitting a CSI report, the CSI report transmitter 1235 may be configured with or otherwise support transmitting a CSI report including a number of bits indicating a set of a plurality of channel resource indicators, the number of bits corresponding to a first number of bits in a first channel resource indicator of the set of a plurality of channel resource indicators based on the number of CMR pairs, a second number of bits in a second channel resource indicator of the set of a plurality of channel resource indicators based on the first number of CMRs in the first subset, and a third number of bits in a third channel resource indicator of the set of a plurality of channel resource indicators based on the second number of CMRs in the second subset.

[0209]

[0213] In some examples, to support transmitting a CSI report, the CSI report transmitter 1235 may be configured with or otherwise support transmitting a CSI report including a number of bits indicating a single channel resource indicator, the number of bits being based on the sum of a first number of CMRs in a first subset, a second number of CMRs in a second subset, and a number of CMR pairs.

[0210]

[0214] In some examples, the first subset includes a first number of unshared CMRs in the first CMR group, and the second subset includes a second number of unshared CMRs in the second CMR group, where the unshared CMRs are separate from the CMRs in the one or more CMR pairs. In some examples, transmitting the CSI report further includes transmitting a CSI report including a number of bits indicating a set of multiple channel resource indicators based on the control signaling indicating that CMR sharing is disabled between the single-TRP channel measurement and the joint-TRP channel measurement, where the number of bits corresponds to a first number of bits in the first channel resource indicator of the set of multiple channel resource indicators based on the number of CMR pairs and a second number of bits in the second channel resource indicator of the set of multiple channel resource indicators based on the first number of unshared CMRs in the first subset and the second number of unshared CMRs in the second subset.

[0212]

[0216] In some examples, the first subset includes a first number of unshared CMRs in the first CMR group, and the second subset includes a second number of unshared CMRs in the second CMR group, where the unshared CMRs are separate from the CMRs in one or more CMR pairs. In some examples, transmitting the CSI report further includes transmitting a CSI report including a number of bits indicating a single channel resource indicator based on control signaling indicating that CMR sharing is disabled between single-TRP channel measurements and joint-TRP channel measurements, where the number of bits is based on the sum of the first number of unshared CMRs in the first subset, the second number of unshared CMRs in the second subset, and the number of CMR pairs.

[0213]
