[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 030,720, filed on May 27, 2020, entitled “CHANNEL MEASUREMENTS AND CONCURRENT MESSAGES FOR USER EQUIPMENT WITH MULTIPLE TRANSMIT-RECEIVE POINTS,” and U.S. Non-Provisional Patent Application No. 17 / 330,017, filed on May 25, 2021, entitled “CHANNEL MEASUREMENTS AND CONCURRENT MESSAGES FOR USER EQUIPMENT WITH MULTIPLE TRANSMIT-RECEIVE POINTS,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] Generally speaking, aspects of the present disclosure relate to wireless communications, and to techniques and apparatus for channel measurement and concurrent messaging for user equipment having multiple transmit / receive points. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may utilize multiple access technologies that are capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of these multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that support communications for multiple user equipment (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or forward link) refers to a communication link from a BS to a UE, and an "uplink" (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, and the like.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region and even global level. NR (also known as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, using new spectrum and integrating better with other open standards using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0031] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in a variety of different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, those skilled in the art should be aware that the scope of the present application is intended to cover any aspect of the content disclosed herein, regardless of whether it is implemented independently of any other aspect of the present application or combined with any other aspect of the present application. For example, any number of aspects set forth herein can be used to implement a device or implementation method. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the disclosure given herein or different from the various aspects of the disclosure given herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements in the claims.

[0032] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0033] It should be noted that while various aspects may be described using terminology typically associated with 5G or NR radio access technologies (RATs), aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0034] Figure 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0035] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown, BS 110a may be a macro BS of macro cell 102a; BS 110b may be a pico BS of pico cell 102b; and BS 110c may be a femto BS of femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0036] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (e.g., direct physical connections or virtual networks) using any suitable transport network.

[0037] The wireless network 100 may also include a relay base station. A relay base station is an entity that can receive data transmissions from an uplink station (e.g., a BS or a UE) and send data transmissions to a downlink station (e.g., a UE or a BS). A relay base station may also be a UE that can relay transmissions for other UEs. Figure 1 In the illustrated example, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay base station, relay base station, relay, or the like.

[0038] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a higher transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0039] The network controller 130 may be coupled to a group of BSs and may provide coordination and control for the BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other, for example, directly or indirectly via a wireless or wired backhaul.

[0040] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be fixed or mobile. UE can also be referred to as a terminal, a mobile station, a subscriber unit, a station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0041] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags that can communicate with a base station, another device (e.g., a remote device) or some other entity. A wireless node may provide, for example, a connection to a network or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses UE 120 components (e.g., a processor component and / or a memory component). In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0042] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0043] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol) and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein performed by base station 110.

[0044] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz; and / or can communicate using an operating frequency band having a second frequency range (FR2), which can range from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "below 6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) band identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise expressly stated, it should be understood that the term "below 6 GHz" and the like, if used herein, can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the term "millimeter wave" and the like, if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0045] As mentioned above, providing Figure 1 As an example. Other examples may be different from the Figure 1 Examples described.

[0046] Figure 2is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 in accordance with the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 452r, where in general T≥1 and R≥1.

[0047] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). If applicable, a transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0048] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMOD) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, etc. In some aspects, one or more components of UE 120 may be included in a housing.

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

[0050] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included in an antenna panel, an antenna group, a set of antenna elements, and / or an antenna array, etc. The antenna panel, antenna group, antenna element set, and / or antenna array may include one or more antenna elements. The antenna panel, antenna group, antenna element set, and / or antenna array may include a coplanar antenna element set and / or a non-coplanar antenna element set. The antenna panel, antenna group, antenna element set, and / or antenna array may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panel, antenna group, a set of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmit and / or receive components, such as Figure 2 One or more components of a

[0051] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., reference 280). Figure 6-Figure 10 described).

[0052] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate to the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 for scheduling the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., reference 200). Figure 6-Figure 10 described).

[0053] As described in more detail elsewhere herein, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Fig. 9 The process of 900 Fig.10 The operations of process 1000 and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed (e.g., directly or after compilation, conversion and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause one or more processors, UE 120 and / or base station 110 to perform or direct, for example Fig. 9 The process of 900 Fig.10 The process 1000 and / or operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among others.

[0054] In some aspects, a first UE (e.g., UE 120a) may include: means for sending a configuration message on a sidelink channel to a second UE (e.g., UE 120e), wherein the configuration message includes: an indication of a first reference signal set associated with a first TRP of the first UE, an indication of a second reference signal set associated with a second TRP of the first UE, and an indication to the second UE to avoid combining measurements based at least in part on the first reference signal set with measurements based at least in part on the second reference signal set; means for sending the first reference signal set on the sidelink channel to the second UE using the first TRP of the first UE; and / or means for sending the second reference signal set on the sidelink channel to the second UE using the second TRP of the first UE. The means used by the first UE to perform the operations described herein may include, for example, one or more of the antenna 252, the demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the modulator 254, the controller / processor 280, or the memory 282.

[0055] In some aspects, a first UE (e.g., UE 120e) may include: means for receiving a configuration message on a sidelink channel from a second UE (e.g., UE 120a), wherein the configuration message includes: an indication of a first reference signal set associated with a first TRP of the second UE, an indication of a second reference signal set associated with a second TRP of the second UE, and an indication to avoid combining measurements based at least in part on the first reference signal set with measurements based at least in part on the second reference signal set; means for measuring the first reference signal set from the second UE on the sidelink channel; and / or means for measuring the second reference signal set from the second UE on the sidelink channel, wherein the measurements based at least in part on the second reference signal set are not combined with the measurements based at least in part on the first reference signal set. The means used by the first UE to perform the operations described herein may include, for example, one or more of the antenna 252, the demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the modulator 254, the controller / processor 280, or the memory 282.

[0056] Although Figure 2 The blocks in the 200 are shown as distinct components, but the functions described above for these blocks may be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0057] As mentioned above, providing Figure 2 As an example. Other examples may be different from the Figure 2 Examples described.

[0058] Figure 3 3 is a diagram illustrating an example 300 of a multi-TRP UE (sometimes referred to as a multi-panel UE) according to the present disclosure. Figure 3 As shown, one or more TRPs 305 may communicate with the same base station 110.

[0059] TRP 305 may correspond to the above combined Figure 1 UE 120 described herein. For example, multiple TRPs 305 may be included in a single UE 120 and may share hardware circuits, hardware controllers, and / or other hardware components. In some aspects, different TRPs 305 may include different antennas (also referred to as panels) on UE 120. Thus, in other examples, TRPs 305 may be referred to as cells, panels, antenna arrays or arrays, etc.

[0060] In some aspects, multiple TRPs 305 may send communications (e.g., the same communications or different communications) in the same transmission time interval (TTI) (e.g., a slot, a mini-slot, a subframe, a symbol, and / or another time domain portion) or in different TTIs using different quasi-co-location (QCL) relationships (e.g., different spatial parameters, different transmission configuration indicator (TCI) states, different precoding parameters, different beamforming parameters, and / or other parameters). In some aspects, the TCI state may be used to indicate one or more QCL relationships. The TRP 305, when included in one or more UEs 120, may be configured to communicate with the base station 110 individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs 305). Similarly, the TRP 305, when included in one or more UEs 120, may be configured to provide services to another UE via a sidelink channel individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs 305), as described below in conjunction with Figure 4-Figure 5 as described.

[0061] Multiple TRPs 305 (shown as TRP A and TRP B), when included in one or more UEs 120, can communicate with the same base station 110 in a coordinated manner (e.g., using coordinated multi-point transmission) to improve reliability and / or increase throughput. Similarly, when multiple TRPs 305 are included in one or more UEs 120, they can communicate with another UE in a coordinated manner (e.g., using coordinated multi-point transmission) via a sidelink channel to improve reliability and / or increase throughput. The TRPs 305 can coordinate such communications via an interface between the TRPs 305 (e.g., a shared hardware controller and / or other shared hardware circuits). Different TRPs 305 can communicate with the base station 110 using different QCL relationships (e.g., different TCI states), different DMRS ports, and / or different layers (e.g., multi-layer communications).

[0062] In the first multi-TRP reception mode (eg, Figure 3In mode 1), a single physical downlink control channel (PDCCH) may be used to schedule downlink data communications for a single physical downlink shared channel (PDSCH). In this case, multiple TRPs 305 (e.g., TRP A and TRP B) may receive communications from the base station 110 on the same PDSCH. For example, for different TRPs 305, communications may be sent using a single codeword with different spatial layers (e.g., where one codeword is mapped to a first set of layers sent by a first TRP 305a and is mapped to a second set of layers sent by a second TRP 305b). As another example, communications may be sent using multiple codewords, where different codewords are received by different TRPs 305 (e.g., using different sets of layers). In either case, different TRPs 305 may use different QCL relationships (e.g., different TCI states) for different DMRS ports corresponding to different layers. For example, the first TRP 305a may use a first QCL relationship or a first TCI state for a first DMRS port set corresponding to a first layer set, and the second TRP 305b may use a second (different) QCL relationship or a second (different) TCI state for a second (different) DMRS port set corresponding to a second (different) layer set. In some aspects, the TCI state in the downlink control information (DCI) (e.g., sent on the PDCCH, such as DCI format 1_0, DCI format 1_1, and / or another DCI format) may indicate a first QCL relationship (e.g., by indicating a first TCI state) and a second QCL relationship (e.g., by indicating a second TCI state). The first and second TCI states may be indicated using a TCI field in the DCI. Typically, the TCI field may indicate a single TCI state (for single TRP reception) or multiple TCI states (for multi-TRP reception discussed herein) in such a multi-TRP reception mode (also referred to as "mode 1").

[0063] In the second multi-TRP reception mode (eg, Figure 3In mode 2), multiple PDCCHs may be used to schedule downlink data communications for multiple corresponding PDSCHs (e.g., one PDCCH for each PDSCH). In this case, the first PDCCH may schedule a first codeword received by the first TRP 305a, and the second PDCCH may schedule a second codeword received by the second TRP 305b. In addition, a first DCI (e.g., received by the first TRP 305) may schedule a first PDSCH communication associated with a first DMRS port set having a first QCL relationship (e.g., indicated by a first TCI state) for the first TRP 305a, and a second DCI (e.g., received by the second TRP 305) may schedule a second PDSCH communication associated with a second DMRS port set having a second QCL relationship (e.g., indicated by a second TCI state) for the second TRP 305b. In this case, the DCI (e.g., having DCI format 1_0, DCI format 1_1, etc.) may indicate a corresponding TCI state of the TRP 305 corresponding to the DCI. The TCI field of the DCI indicates a corresponding TCI state (eg, the TCI field of the first DCI indicates a first TCI state, and the TCI field of the second DCI indicates a second TCI state).

[0064] Although described above with respect to communicating with one or more base stations 110, the description is equally applicable to multiple TRPs 305 communicating with another UE on a sidelink channel. Figure 3 As an example. Other examples may be different from the Figure 3 Examples described.

[0065] Figure 4 4 is a diagram illustrating an example 400 of sidelink communications according to the present disclosure. Figure 4 As shown, the first UE 405-1 can communicate with the second UE 405-2 (and one or more other UEs 405) via one or more sidelink channels 410. UE 405-1 and 405-2 can use the sidelink channel 410 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication and / or vehicle to pedestrian (V2P) communication) and / or mesh network to communicate. In some aspects, UE 405 (e.g., UE 405-1 and / or UE 405-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, one or more sidelink channels 410 can use a PC5 interface and / or can operate in a high frequency band (e.g., 5.9 GHz band). Additionally or alternatively, UE 405 can use global navigation satellite system (GNSS) timing to synchronize the timing of TTI (e.g., frame, subframe, time slot or symbol).

[0066] like Figure 4 As further shown, the one or more sidelink channels 410 may include a physical sidelink control channel (PSCCH) 415, a physical sidelink shared channel (PSSCH) 420, and / or a physical sidelink feedback channel (PSFCH) 425. The PSCCH 415 may be used to transmit control information, similar to the PDCCH and / or physical uplink control channel (PUCCH) used for cellular communication with the base station 110 via an access link or access channel. The PSSCH 420 may be used to transmit data, similar to the PDSCH and / or physical uplink shared channel (PUSCH) used for cellular communication with the base station 110 via an access link or access channel. For example, the PSCCH 415 may carry sidelink control information (SCI) 430, which may indicate various control information for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, and / or space resources), where a transport block (TB) 435 may be carried on the PSSCH 420. The TB 435 may include data. The PSFCH 425 may be used to transmit sidelink feedback 440, such as hybrid automatic repeat request (HARQ) feedback (eg, acknowledgement or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), and / or scheduling request (SR).

[0067] In some aspects, one or more sidelink channels 410 may use a resource pool. For example, a scheduling assignment (e.g., included in SCI 430) may be sent in a subchannel using specific resource blocks (RBs) across time. In some aspects, a data transmission associated with a scheduling assignment (e.g., on PSSCH 420) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, a scheduling assignment and associated data transmission are not sent on adjacent RBs.

[0068] In some aspects, UE 405 may operate using a transmission mode in which resource selection and / or scheduling is performed by UE 405 (e.g., rather than base station 110). In some aspects, UE 405 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, UE 405 may measure RSSI parameters associated with various sidelink channels (e.g., sidelink-RSSI (S-RSSI) parameters), may measure RSRP parameters associated with various sidelink channels (e.g., PSSCH-RSRP parameters), may measure RSRQ parameters associated with various sidelink channels (e.g., PSSCH-RSRQ parameters), etc., and may select a channel for transmission of sidelink communications based at least in part on these measurements.

[0069] Additionally or alternatively, the UE 405 may perform resource selection and / or scheduling using the SCI 430 received in the PSCCH 415, which may indicate occupied resources and / or channel parameters. Additionally or alternatively, the UE 405 may perform resource selection and / or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 405 may use for a particular set of subframes).

[0070] In a transmission mode in which resource selection and / or scheduling is performed by the UE 405, the UE 405 may generate a sidelink grant and may send the grant in the SCI 430. The sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) for an upcoming sidelink transmission, such as one or more resource blocks to be used for the upcoming sidelink transmission on the PSSCH 420 (e.g., for TB 435), one or more subframes to be used for the upcoming sidelink transmission, and / or an MCS to be used for the upcoming sidelink transmission. In some aspects, the UE 405 may generate a sidelink grant indicating one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of the sidelink transmission. Additionally or alternatively, the UE 405 may generate a sidelink grant for event-driven scheduling (e.g., for an on-demand sidelink message).

[0071] As mentioned above, providing Figure 4 As an example. Other examples may be different from the Figure 4 Examples described.

[0072] Figure 5 5 is a diagram illustrating an example 500 of sidelink and access link communications according to the present disclosure. Figure 5 As shown, the transmitter (Tx) / receiver (Rx) UE 505 and the Rx / Tx UE 510 can communicate with each other via a side link, as described above in conjunction with Figure 4 As further shown, in some sidelink modes, the base station 110 may communicate with the Tx / Rx UE 505 via a first access link. Additionally or alternatively, in some sidelink modes, the base station 110 may communicate with the Rx / Tx UE 510 via a second access link. The Tx / Rx UE 505 and / or the Rx / Tx UE 510 may correspond to one or more UEs described elsewhere herein, e.g. Figure 1120. Thus, a direct link between UE 120 (e.g., via a PC5 interface) may be referred to as a sidelink, and a direct link between base station 110 and UE 120 (e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be sent via a sidelink, and access link communications may be sent via an access link. Access link communications may be downlink communications (from base station 110 to UE 120) or uplink communications (from UE 120 to base station 110).

[0073] As mentioned above, providing Figure 5 As an example. Other examples may be different from the Figure 5 Examples described.

[0074] In some cases, as described above, a UE may include multiple TRPs. The TRPs may be several meters apart (e.g., like the front and rear panels of a car or other vehicle) or may be tens of meters apart (e.g., like in a truck, trailer, and / or other large UE). For a multi-TRP UE, some TRPs may have higher signal reliability and / or strength for transmission and reception than other TRPs, depending on environmental factors (e.g., intervening objects that interfere with transmissions to and from one TRP but not another TRP). Additionally or alternatively, some TRPs may have higher signal reliability and / or strength for transmission or reception than other TRPs, depending on the different distances between the TRP and the intended recipient of the transmission or the sender associated with the reception, respectively. For example, one TRP may be closer to a peer UE and / or base station than another TRP. These reliability and / or strength differences may be particularly large when a multi-TRP UE communicates with a peer UE on a sidelink channel.

[0075] The techniques and apparatus described herein enable a multi-TRP UE (e.g., Figure 6-Figure 8 UE 120a, as described below, can measure separate indicators of signal strength of the TRP (e.g., RSRP parameters, CQI parameters, signal to interference and noise ratio (SINR), and / or other parameters). By measuring the separate indicators, UE 120a can obtain a more accurate measurement of signal quality and / or reliability from the TRP. Thus, UE 120a can use these indicators to coordinate with multiple peer UEs (e.g., Figure 7 120b and 120c, as described below), which reduces latency and effectively reuses network resources to reduce overhead. Additionally or alternatively, UE 120a may use these indicators to coordinate to a single peer UE (e.g., Figure 8120b, as described below), which increases reliability and signal strength. In some aspects, UE 120a can use combined transmission to additionally or alternatively enable a higher MCS to save network resources during transmission.

[0076] Figure 6 6 is a diagram illustrating an example 600 of measuring signal quality from a multi-TRP UE 120a according to the present disclosure. Figure 6 As shown, example 600 includes communicating with a second UE 120b (e.g., on a sidelink channel, as described above in conjunction with Figure 4-Figure 5 305a and 305b). Although the following description will focus on a UE 120a having two TRPs 305a and 305b, the description is similarly applicable to a UE 120a having additional TRPs (e.g., three TRPs, four TRPs, etc.).

[0077] As indicated by reference numeral 610, the multi-TRP UE 120a may send a configuration message on a sidelink channel and the second UE 120b may receive the configuration message on the sidelink channel. In some aspects, the configuration message may include: an indication of a first reference signal set associated with a first TRP 305a of the multi-TRP UE 120a, an indication of a second reference signal set associated with a second TRP 305b of the multi-TRP UE 120a, and an indication to the second UE 120b to avoid combining measurements based at least in part on the first reference signal set with measurements based at least in part on the second reference signal set.

[0078] In some aspects, the multi-TRP UE 120a may use the first TRP 305a and / or the second TRP 305b to send configuration messages. Figure 6 As shown, the second UE 120b can receive a configuration message from the multi-TRP UE 120a on the sidelink channel.

[0079] In some aspects, the configuration message may be included in a radio resource control (RRC) message. Additionally or alternatively, the configuration message may be included in an SCI.

[0080] In some aspects, the indication of the first reference signal set may include at least one first measurement gap offset for the first reference signal set and at least one first measurement gap period for the first reference signal set. Additionally or alternatively, the indication of the second reference signal set includes at least one second measurement gap offset for the second reference signal set and at least one second measurement gap period for the second reference signal set.

[0081] Thus, at least one first measurement gap offset may be different from at least one second measurement gap offset. Figure 6 In the two TRPs 305a and 305b depicted in FIG, the indication of the first reference signal set may include an offset and a period (2, 10), and the indication of the second reference signal set may include an offset and a period (5, 10). These indications may be separate from each other or combined in a list (e.g., {(2, 10), (5, 10)}) for encoding in the message. In this example, these offsets indicate that the second and fifth subframes are used for reference signal measurements (e.g., channel state information reference signal (CSI-RS) measurements). As used herein, a "subframe" may refer to a portion of a radio frame within an LTE, 5G, or other wireless communication structure. In some aspects, a subframe may include one or more time slots, each of which has one or more symbols. In addition, a "symbol" may refer to an OFDM symbol or other similar symbol within a time slot. Thus, one TRP (e.g., the first TRP 305a) may send a first reference signal set in every second subframe, while another TRP (e.g., the second TRP 305b) may send a second reference signal set in every fifth subframe.

[0082] In this example, at least one first measurement gap period includes the same period as at least one second measurement gap period. Alternatively, at least one first measurement gap period may include a period different from at least one second measurement gap period. For example, the indication of the first reference signal set may include an offset and a period (2, 10), and the indication of the second reference signal set may include an offset and a period (5, 20). The at least one first measurement gap period and the at least one second measurement gap period may be selected to avoid conflicts (e.g., by selecting the period such that the modulus of the at least one second period and the at least one first period is zero, as shown in the above example).

[0083] Alternatively, the multi-TRP UE 120a may prioritize the first reference signal set over the second reference signal set, or may prioritize the second reference signal set over the first reference signal set, such that only the first reference signal set signal or the second reference signal set signal, respectively, is transmitted during any subframe (or time slot) where a collision is expected. In some aspects, the TRPs may also measure each other's reference signals during transmission (e.g., as described below in conjunction with Figure 8 described).

[0084] The indication may additionally or alternatively include information identifying at least one first port for the first reference signal set and at least one second port for the second reference signal set.Thus, in addition to or instead of being orthogonal in time as described above, the first reference signal set and the second reference signal set may also be orthogonal in frequency.

[0085] Therefore, as described above, the first reference signal set and the second reference signal set may be multiplexed within one or more subframes or time slots in the measurement period. The first reference signal set and the second reference signal set may be multiplexed using time division multiplexing, code division multiplexing, frequency division multiplexing, or a combination thereof.

[0086] As indicated by reference numeral 615a, the multi-TRP UE 120a may transmit a first set of reference signals to a second UE 120b on a sidelink channel using the first TRP 305a of the UE 120a. For example, the first set of reference signals may include a CSI-RS, as described above.

[0087] Thus, the second UE 120b may measure the first set of reference signals from the multi-TRP UE 120a on the sidelink channel. For example, the second UE 120b may determine one or more indicators of signal quality and / or strength based on the first set of reference signals.

[0088] As indicated by reference numeral 615b, the multi-TRP UE 120a may transmit a second set of reference signals to a second UE 120b on a sidelink channel using the second TRP 305b of the UE 120a. For example, the second set of reference signals may include a CSI-RS, as described above.

[0089] Thus, the second UE 120b may measure a second set of reference signals from the multi-TRP UE 120a on the sidelink channel. For example, the second UE 120b may determine one or more indicators of signal quality and / or strength based on the first set of reference signals.

[0090] As described above, the second UE 120b does not combine measurements based at least in part on the second reference signal set with measurements based at least in part on the first reference signal set. For example, the configuration message from the multi-TRP UE 120a may include at least one bit or other information indicating that the second UE 120b does not combine measurements based at least in part on the second reference signal set with measurements based at least in part on the first reference signal set.

[0091] As indicated by reference numeral 620, the second UE 120b may send and the multi-TRP UE 120a may receive at least one report calculated by the second UE 120b. In some aspects, the second UE 120b may send the at least one report based at least in part on measuring the first set of reference signals and measuring the second set of reference signals. Thus, the multi-TRP UE 120a may receive the at least one report based at least in part on sending the first set of reference signals and sending the second set of reference signals. Figure 6 As shown, the multi-TRP UE 120a may receive the at least one report using a first TRP 305a (shown by reference numeral 620a) and / or a second TRP 305b (shown by reference numeral 620b).

[0092] In some aspects, at least one report includes at least one of a first SINR, a first RSRP, or a combination thereof for a first reference signal set, and at least one of a second SINR, a second RSRP, or a combination thereof for a second reference signal set. Additionally or alternatively, at least one report may include a signal-to-interference ratio (SIR) and / or other measurement results.

[0093] In some aspects, the at least one report may include a first report based at least in part on measuring a first reference signal set and a second report based at least in part on measuring a second reference signal set. For example, the second UE 120b may generate a first CQI report based at least in part on measuring the first reference signal set and generate a second CQI report based at least in part on measuring the second reference signal set. Thus, the second UE 120b may send two or more reports to the multi-TRP UE 120a, where each report is associated with a different TRP.

[0094] Alternatively, at least one report may include a report with an index that associates a first portion of the report with a first reference signal set and a second portion of the report with a second reference signal set. For example, the second UE 120b may generate a single CQI report in which the measurement results are included in a list with identifiers corresponding to different TRPs of the multi-TRP UE 120a. For example, the index of the TRP may map the identifiers included in the measurement list to the corresponding TRP.

[0095] By separately configuring the measurement of reference signals from the TRPs, the multi-TRP UE 120a can receive more accurate signal quality reports from the TRPs. In addition, the multi-TRP UE 120a can use the reports generated as described above to reduce the latency and overhead of simultaneous transmissions (e.g., as described below in conjunction with Figure 7 as described) and / or improving the signal quality and / or reliability of the combined transmission (e.g., as described below in conjunction with Figure 8 described).

[0096] As mentioned above, providing Figure 6 As an example. Other examples may be different from the Figure 6 Examples described.

[0097] Figure 7 7 is a diagram illustrating an example 700 of simultaneous transmissions from multiple TRP UEs 120a in accordance with the present disclosure. Figure 7 As shown, example 700 includes communicating with a second UE 120b and a third UE 120c (e.g., on a sidelink channel, as described above in conjunction with Figure 4-Figure 5 10. The UE 120a described above may be a UE having multiple TRPs (e.g., a first TRP 305a and a second TRP 305b). Although the following description will focus on a UE 120a having two TRPs 305a and 305b, the description is similarly applicable to a UE 120a having additional TRPs (e.g., three TRPs, four TRPs, etc.).

[0098] In example 700, the multi-TRP UE 120a may determine, based at least in part on at least one report, that the multi-TRP UE 120a is capable of transmitting to the second UE 120b and the third UE 120c simultaneously. For example, the UE 120a may receive the information described above in conjunction with Figure 6 At least one report described.

[0099] In some aspects, determining that the multi-TRP UE 120a is capable of transmitting to the second UE 120b and the third UE 120c simultaneously may include determining that at least one of a first SIR associated with the second UE 120b, a second SIR associated with the third UE 120c, or a combination thereof satisfies a condition. For example, the multi-TRP UE 120a may determine whether the first SIR, the second SIR, a combination of the first SIR and the second SIR, and / or a minimum (or maximum) of the first SIR and the second SIR satisfies a threshold.

[0100] In one example, the second UE 120b may have measured a signal strength of -44dBm based at least in part on the first reference signal set from the first TRP 305a, and a signal strength of -60dBm based at least in part on the second reference signal set from the second TRP 305b. In addition, the third UE 120c may have measured a signal strength of -58dBm based at least in part on the first reference signal set from the first TRP 305a, and a signal strength of -45dBm based at least in part on the second reference signal set from the second TRP 305b. Thus, the multi-TRP UE 120a may determine (e.g., based at least in part on the above measurements and / or based on at least one report) that the first SIR associated with the second UE 120b is 14dB and the second SIR associated with the third UE 120c is 15dB. In this example, the multi-TRP UE 120a may determine that the multi-TRP UE 120a is able to transmit to the second UE 120b and the third UE 120c simultaneously (eg, when the condition is that the minimum SIR is 14 dB or less).

[0101] In some aspects, determining that the multi-TRP UE 120a is capable of transmitting to the second UE 120b and the third UE 120c simultaneously may include adding the second UE 120b and the third UE 120c as a set to a list of UEs suitable for simultaneous transmission. For example, the multi-TRP 120a may maintain a list of UE sets to which simultaneous transmissions may be made.

[0102] In some aspects, the multi-TRP UE 120a may maintain the list using an iterative process. For example, the multi-TRP UE 120a may select a minimum SIR and / or other condition based at least in part on a measurement of signal strength. Based at least in part on the condition, the multi-TRP UE 120a may add a UE pair (or other set including three or more UEs) to the list based at least in part on satisfying the condition (e.g., as described above, by having a first SIR and a second SIR that satisfy the minimum SIR). The multi-TRP UE 120a may add a set of UEs to the list by modifying the condition based at least in part on the number of successful transmissions to one or more sets of UEs on the list of UEs suitable for simultaneous transmission. For example, after n successful transmissions to the set of UEs on the list, the multi-TRP UE 120a may lower the minimum SIR and / or otherwise modify the condition so that a new set of UEs satisfying the modified condition is added to the list. Similarly, the multi-TRP UE 120a may remove a set of UEs from the list by modifying the condition based at least in part on the number of unsuccessful transmissions to one or more sets of UEs on the list of UEs suitable for simultaneous transmission. For example, after m unsuccessful transmissions to the set of UEs on the list, the multi-TRP UE 120a may increase the minimum SIR and / or otherwise modify the condition such that one or more sets of UEs that do not meet the modified condition are removed from the list.

[0103] like Figure 7 As shown in the figure and in conjunction with reference numeral 705, the multi-TRP UE 120a can send a signal (e.g., a first message) to the second UE 120b on the first resource and using the first TRP 305a. Figure 7 As further shown in the figure and in conjunction with reference numeral 710, the multi-TRP UE 120a can send a signal (e.g., a second message) to the third UE 120c on a second resource that at least partially overlaps the first resource and using the second TRP 305b. For example, the first resource and the second resource can overlap in time and / or frequency.

[0104] In some aspects, the multi-TRP UE 120a may transmit to the second UE 120b and the third UE 120c based at least in part on determining that the multi-TRP UE 120a is capable of transmitting to the second UE 120b and the third UE 120c simultaneously. For example, as described above, one or more measurements of signal strength associated with the second UE 120b and / or the third UE 120c may satisfy the condition set by the multi-TRP UE 120a. By using Figure 7As shown in the simultaneous transmission, the multi-TRP UE 120a reduces resource overhead by transmitting to the second UE 120b and the third UE 120c using at least partially overlapping resources. Additionally, the multi-TRP UE 120a reduces the latency of communicating with the second UE 120b and the third UE 120c because the communication to the second UE 120b can be at least partially simultaneous in time with the communication to the third UE 120c.

[0105] As mentioned above, providing Figure 7 As an example. Other examples may be different from the Figure 7 Examples described.

[0106] Figure 8 8 is a diagram illustrating an example 800 of combined transmissions from a multi-TRP UE 120a in accordance with the present disclosure. Figure 8 As shown, example 800 includes communicating with a second UE 120b (e.g., on a sidelink channel, as described above in conjunction with Figure 4-Figure 5 305a and 305b). Although the following description will focus on a UE 120a having two TRPs 305a and 305b, the description is similarly applicable to a UE 120a having additional TRPs (e.g., three TRPs, four TRPs, etc.).

[0107] In example 800, the multi-TRP UE 120a may adjust at least one of the transmission power of the first TRP 305a, the transmission power of the second TRP 305b, or a combination thereof based at least in part on at least one signal quality report associated with the first TRP 305a and the second TRP 305b. For example, the multi-TRP UE 120a may adjust at least one of the transmission power of the first TRP 305a, the transmission power of the second TRP 305b, or a combination thereof based on the above combination of Figure 6 Described at least one received report is used to adjust the transmission power of the first TRP 305a, the transmission power of the second TRP 305b, or a combination thereof.

[0108] In some aspects, the multi-TRP UE 120a may be configured for a first MCS, and the adjustment may be based at least in part on configuring the multi-TRP UE 120a for a second MCS. For example, the second MCS may be a higher MCS than the first MCS. Thus, the multi-TRP UE 120a may use fewer network resources when transmitting using the second MCS than when transmitting using the first MCS.

[0109] Additionally or alternatively, the adjustment may be based at least in part on at least one measurement result (included in at least one report) satisfying at least one condition. For example, when a first measurement of a signal strength associated with the first TRP 305a and the second UE 120b and / or a second measurement of a signal strength associated with the second TRP 305b and the second UE 120b satisfies a threshold, the multi-TRP UE 120a may adjust the transmission power of the first TRP 305a, the transmission power of the second TRP 305b, or a combination thereof. For example, the multi-TRP UE 120a may determine whether a first RSRP associated with the first TRP 305a and the second UE 120b, a second RSRP associated with the second TRP 305b and the second UE 120b, a combination of the first RSRP and the second RSRP, and / or a minimum value (or maximum value) of the first RSRP and the second RSRP satisfies a threshold.

[0110] As indicated by reference numerals 805a and 805b, the UE 120a may send a message or signal from both the first TRP 305a and the second TRP 305b to the second UE 120b. For example, the multi-TRP UE 120a may transmit using both the first TRP 305a and the second TRP 305b as described above, based at least in part on at least one report (e.g., when a first RSRP associated with the first TRP 305a and the second UE 120b and / or a second RSRP associated with the second TRP 305b and the second UE 120b meets a threshold), and / or a decision based at least in part on at least one report (e.g., by determining that the multi-TRP UE 120a is able to use a higher MCS with the UE 120b by adjusting the transmit power of the first TRP 305a, the transmit power of the second TRP 305b, or a combination thereof).

[0111] In some aspects, the second UE 120b may combine decoded data from signals sent from both the first TRP and the second TRP. For example, the multi-TRP UE 120a may have sent an SCI to the second UE 120b that includes an indication to combine decoded data from signals sent from both the first TRP and the second TRP. In some aspects, the multi-TRP UE 120a may have sent a QCL indicator, etc., to trigger the second UE 120b to combine the decoded data. In some aspects, the second UE 120b may combine the decoded data using a log likelihood ratio (LLR) and / or another decoding technique.

[0112] Additionally or alternatively, and as described above, the second UE 120b may be configured (at least initially) for the first MCS and may receive the message or signal using the second MCS. For example, the second MCS may be a higher MCS than the first MCS and enabled by a combined transmission from the first TRP 305a and the second TRP 305b. Thus, the second MCS may require fewer network resources from the multi-TRP UE 120a during transmission than the first MCS.

[0113] In some aspects, the multi-TRP UE 120a may apply resource exclusion prior to using the combined transmission as described above. For example, the multi-TRP UE 120a may determine resource exclusion for the first TRP 305a and resource exclusion for the second TRP 305b based at least in part on the adjustment. For example, after the adjustment, the multi-TRP UE 120a may send CSI-RS (and / or other reference signals) between TRPs (e.g., from the first TRP 305a to the second TRP 305b and / or from the second TRP 305b to the first TRP 305a) for measurement (e.g., as RSRP parameters and / or other parameters). Additionally or alternatively, the multi-TRP UE 120a may perform measurements using synchronization signal blocks (SSBs), DMRS, and / or other reference signals. The multi-TRP UE 120a may transmit to the second UE 120b using both the first TRP 305a and the second TRP 305b based at least in part on resource exclusion, wherein the resource exclusion is based at least in part on the adjusted measurements.

[0114] In some aspects, determining resource exclusion can be based at least in part on a first resource mapping associated with the first TRP 305a and a second resource mapping associated with the second TRP 305b. For example, the multi-TRP UE 120a can select one or more resources from the first resource mapping and one or more resources from the second resource mapping such that all selected resources satisfy one or more resource exclusion criteria applied by the multi-TRP UE 120a.

[0115] By using combined transmissions as described above, the multi-TRP UE 120a can enable a higher MCS for transmission to the second UE 120b than when using only one TRP. Therefore, the multi-TRP UE 120a uses fewer network resources when transmitting at a higher MCS. Additionally or alternatively, the multi-TRP UE 120a improves signal quality and / or reliability by using more than one TRP to transmit to the second UE 120b. This can also reduce latency because the multi-TRP UE 120a can use more than one TRP to send a message or signal, rather than repeatedly sending the message or signal as is often required when signal quality and / or reliability is low.

[0116] As mentioned above, providing Figure 8 As an example. Other examples may be different from the Figure 8 Examples described.

[0117] Fig. 9 900 is a diagram illustrating an example process 900 performed, for example, by a first UE according to the present disclosure. Example process 900 is an example in which a first UE (eg, multi-TRP UE 120a) performs operations associated with channel measurements and concurrent messaging for UEs with multiple TRPs.

[0118] like Fig. 9 As shown, in some aspects, process 900 may include: sending a configuration message to a second UE (e.g., UE 120b) on a sidelink channel (block 910). For example, a first UE (e.g., using one or more of antenna 252, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may send a configuration message to a second UE on a sidelink channel, as described above. In some aspects, the configuration message includes: an indication of a first reference signal set associated with a first TRP of the first UE, an indication of a second reference signal set associated with a second TRP of the first UE, and an indication to the second UE to avoid combining measurements based at least in part on the first reference signal set with measurements based at least in part on the second reference signal set.

[0119] like Fig. 9 As further shown, in some aspects, process 900 may include sending a first set of reference signals to a second UE on a sidelink channel using a first TRP of the first UE (block 920). For example, the first UE (e.g., using one or more of antenna 252, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may send a first set of reference signals to a second UE on a sidelink channel using the first TRP of the first UE, as described above.

[0120] like Fig. 9 As further shown, in some aspects, process 900 may include sending a second set of reference signals on a sidelink channel to a second UE using a second TRP of the first UE (block 930). For example, the first UE (e.g., using one or more of antenna 252, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may send a second set of reference signals on a sidelink channel to a second UE using the second TRP of the first UE, as described above.

[0121] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0145] Fig.10 is a diagram illustrating an example process 1000 performed, for example, by a first UE, according to various aspects of the present disclosure. Example process 1000 is an example in which a first UE (e.g., UE 120b) performs operations associated with channel measurements and concurrent messaging for a UE with multiple TRPs.
