Channel state information reporting for beam prediction based on multiple transmit and receive points

Abstract

Methods, systems, and devices for wireless communication are described. In some aspects, a UE may predict and report signal strength information associated with channel resources of a channel prediction resource (CPR) set based on measured signal strength of channel resources of a channel measurement resource (CMR) set of each of a plurality of transmit and receive points (TRPs). For example, each TRP may be associated with a CMR set and a CPR set, and the UE may measure a signal strength of a channel resource of each CMR set, and may predict a signal strength of a channel resource of the associated CPR set using the measured signal strength. The UE may report, via channel state information (CSI) reports, predicted signal strengths of a set of CPRs in pairs via one or more channel resource pairs. In some aspects, the UE may include both predicted signal strength and measured signal strength in the CSI report.

Description

Background Art

[0001] The following relates to wireless communications, including channel state information (CSI) reporting for beam prediction based on multiple transmit and receive points (TRPs).

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems can support 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) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques 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, each of which supports wireless communication for communication devices, which may be referred to as user equipment (UE). Summary of the Invention

[0003] The described technology relates to improved methods, systems, devices, and apparatuses that support channel state information (CSI) reporting for beam prediction based on multiple transmit and receive points (TRPs). For example, a user equipment (UE) may predict and report signal strength information associated with channel resources of a channel prediction resource (CPR) set based on the measured signal strength of the channel resources of a channel measurement resource (CMR) set for each of a plurality of TRPs. For example, each TRP may be associated with a CMR set and a CPR set, and the UE may measure the signal strength of the channel resources of each CMR set and may use the measured signal strength to predict the signal strength of the channel resources of the associated CPR set. The UE may report the predicted signal strengths of these CPR sets in a paired manner via one or more channel resource pairs.

[0064] In some deployment scenarios, such as multiple transmit and receive (TRP) deployment scenarios, a user equipment (UE) may receive signaling from multiple TRPs simultaneously. To support such multiple TRP (mTRP) deployment scenarios, the UE may send one or more channel state information (CSI) reports to one or more TRPs in the multiple TRPs, wherein the CSI report may include information indicating one or more measured signal strengths and information indicating which one or more channel measurement resources (CMRs) the measured signal strengths correspond to. In some aspects, for example, a first TRP may send reference signals via a first set of CMRs (e.g., CMRs of a first CMR set) when switching between different transmit beams, and a second TRP may send reference signals via a second set of CMRs (e.g., CMRs of a second CMR set) when switching between different transmit beams. Thus, the UE may indicate which CMRs have the relatively largest signal strengths to implicitly indicate which transmit beams the first TRP and the second TRP may use for downlink transmissions to the UE.

[0065] In some systems, the UE may use a model, such as an artificial intelligence (AI) or machine learning (ML) model, to predict information associated with a first set of beams based on a set of measurements of a second set of beams. For example, the UE may receive information associated with a set A of beams and a set B of beams, and may use signal strength measurements of the set B beams to predict signal strength measurements of the set A beams. However, in some systems, the UE and the TRPs may lack a mutually understood mechanism by which the UE may predict and report signal strengths for beams of multiple TRPs. As a result, the UE and any associated TRPs may be unable to use or utilize the UE's beam prediction capabilities in an mTRP deployment scenario, which may prevent the UE and the TRPs from experiencing the lower signaling overhead and reduced power consumption costs associated with using beam prediction at the UE.

[0066] In some implementations, the UE and the multiple TRPs may support one or more configuration or signaling-based mechanisms, according to which the UE may predict and report signal strength information associated with the set A of beams based on the measured signal strength of the set B of beams of each TRP in the multiple TRPs. For example, the UE may receive information such as CSI report setting information from a network entity (e.g., from one of the multiple TRPs, or from another network entity that controls or is associated with the multiple TRPs), and the CSI report setting information may include information indicating a first CMR set associated with the first TRP and a second CMR set associated with the second TRP. The UE and the multiple TRPs may also support one or more signaling mechanisms, such as radio resource control (RRC) signaling, one or more medium access control (MAC)-control elements (CEs), or downlink control information (DCI), via which the UE and the multiple TRPs may associate or pair one or both of the first CMR set and the second CMR set with the first channel prediction resource (CPR) set and the second CPR set, respectively. As described herein, a CPR set may refer to a set of channel resources that are configured or used for beam prediction instead of or in addition to being used for channel measurement. In other words, a CPR set may be associated with a set of beams A, and an associated or paired CMR set may be associated with a set of beams B.

[0067] Therefore, in a specific implementation where both the first CMR set and the second CMR set are configured, activated, or triggered for CSI reporting and are associated with corresponding CPR sets, the UE may measure a set of signal strengths of channel resources of the first CMR set and the second CMR set, and may use the set of measured signal strengths of the first CMR set and the second CMR set to predict the signal strengths of channel resources of the first CPR set and the second CPR set, respectively. In some aspects, the UE may predict the signal strengths associated with the channel resources of the first CPR set and the second CPR set in a pairwise manner. For example, the UE may predict the signal strengths associated with one or more channel resource pairs, where each channel resource pair includes a corresponding first channel resource from the first CPR set and a corresponding second channel resource from the second CPR set. The UE and the TRP may support one or more quantization schemes, according to which the UE may include information indicating the set of predicted signal strengths and information indicating which CPRs the predicted signal strengths correspond to in the CSI report.

[0068] Specific implementations of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. For example, as a result of supporting a configuration or signaling-based mechanism according to which the UE can predict and report signal strength in an mTRP deployment, the UE and multiple TRPs can achieve lower signaling overhead and reduced measurement-related power consumption costs. In other words, implementing beam prediction for simultaneous mTRP downlink transmissions can reduce the amount of reference signals transmitted by each of the multiple TRPs and can reduce the amount of resources via which the UE monitors and measures signal strength. In addition, the UE and multiple TRPs can support various types of quantization schemes according to which the UE can quantize and report both measured signal strength and predicted signal strength via CSI reports, and such various quantization schemes can be used to achieve a configurable balance between lower overhead, higher accuracy, and lower complexity. In addition, supporting the beam prediction process in mTRP deployments can contribute to the wider adoption of one or both of AI or ML-based beam prediction and mTRP system configurations, which can increase connectivity and reduce latency. Thus, UEs and multiple TRPs can employ the described techniques in various scenarios, including beam management processes, and can experience higher data rates, greater capacity, and higher spectral efficiency.

Various aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to CSI reporting for mTRP-based beam prediction.

[0070] Figure 1 An example of a wireless communication system 100 that supports CSI reporting for mTRP-based beam prediction according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some implementations, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies (including future systems and radio technologies not explicitly mentioned herein).

[0071] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some implementations, the network entities 105 and the UEs 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entities 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UEs 115 and the network entities 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entities 105 and the UEs 115 may support signal communication according to one or more radio access technologies (RATs).

[0072] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices that take different forms or have different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. The UEs 115 described herein may be capable of supporting communication with various types of devices, such as Figure 1 105 or other UEs 115 or network entities 105 as shown.

[0073] As described herein, a node (which may be referred to as a node, network node, network entity, or wireless node) may include, may be, or may be included in (e.g., as a component of) a base station (e.g., any base station described herein), a UE (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, an integrated access and backhaul (IAB) node, a distributed unit (DU), a central unit (CU), a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, the network node may be a UE. For another example, the network node may be a base station or a network entity. For another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a UE. In another aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a base station. In yet other aspects of this example, the first network node, the second network node, and the third network node may be different from these examples. Similarly, references to a UE, a base station, an apparatus, a device, a computing system, etc., may include disclosures of the UE, base station, apparatus, device, computing system, etc. as network nodes. For example, a disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. Consistent with the present disclosure, once a specific example is expanded upon according to the present disclosure (e.g., a UE being configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node), a broader example of the narrower example may be interpreted inversely, but in a broad, open-ended manner. In the above example where a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more components, a first processing entity, etc., configured to receive information; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, a second processing entity, etc.

[0074] As described herein, various terms may be used to describe the communication of information (e.g., any information, signal, etc.) in various aspects. Disclosure of one communication term includes disclosure of the other communication terms. For example, a first network node may be described as being configured to send information to a second network node. In this example and consistent with the present disclosure, disclosure that the first network node is configured to send information to the second network node includes disclosure that the first network node is configured to provide, transmit, output, communicate, or send information to the second network node. Similarly, in this example and consistent with the present disclosure, disclosure that the first network node is configured to send information to the second network node includes disclosure that the second network node is configured to receive, obtain, or decode information provided, transmitted, output, communicated, or sent by the first network node.

[0075] In some implementations, the network entities 105 can communicate with the core network 130, with each other, or both. For example, the network entities 105 can communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some implementations, the network entities 105 can communicate with each other directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some implementations, the network entities 105 can communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol), or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155.

[0076] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next-generation Node B, or a gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home Node B, a Home evolved Node B, or other suitable terminology). In some implementations, the network entity 105 (e.g., the base station 140) may be implemented in a converged (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as the base station 140).

[0077] In some implementations, the network entity 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that can be configured to utilize protocol stacks that are physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 can include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 can also be referred to as a radio head, an intelligent radio head, a remote radio head (RRH), a remote radio unit (RRU), or a TRP. One or more components of the network entity 105 in the disaggregated RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some implementations, one or more network entities 105 of the disaggregated RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0078] The functional split between the CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at the CU 160, DU 165, or RU 170. For example, a functional split of the protocol stack can be employed between the CU 160 and DU 165 such that the CU 160 can support one or more layers of the protocol stack and the DU 165 can support one or more different layers of the protocol stack. In some implementations, the CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., RRC, Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as Layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, MAC layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 can be within the protocol layer (e.g., some functions of the protocol layer can be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 can be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 can be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and the DU 165 can be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some implementations, the midhaul communication link 162 or the fronthaul communication link 168 can be implemented based on interfaces (e.g., channels) between layers of a protocol stack supported by respective network entities 105 that communicate via these communication links.

[0079] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources used for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication link 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by the DU 165 of the coupled IAB donor. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some implementations, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0080] In the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support CSI reporting for mTRP-based beam prediction as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0081] The UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. The UE 115 may also include or may 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 specific implementations, the UE 115 may include or may 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, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0082] The UE 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 well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0083] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates 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 for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between those devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0084] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to the resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. 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), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communications with UE 115.

[0085] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f 0 seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources 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).

[0086] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some implementations, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended to the front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0087] A subframe, slot, mini-slot, or symbol can be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and can be referred to as a Transmit Time Interval (TTI). In some implementations, the TTI duration (e.g., the number of symbol periods in a TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0088] Physical channels may be multiplexed according to various techniques for communication using a carrier. For example, physical control channels and physical data channels may be multiplexed using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques for signaling via a downlink carrier. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth of a carrier or a subset of that bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region for control information according to one or more search space sets, and 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 of a control channel candidate may refer to the amount of 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 transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0089] In some implementations, the network entities 105 (e.g., base stations 140, RUs 170) can be mobile and, therefore, provide communication coverage for mobile coverage areas 110. In some implementations, different coverage areas 110 associated with different technologies can overlap, but can be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies can be supported by different network entities 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0090] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 can be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication can include private communication or group communication and can be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency and ultra-reliable low-latency can be used interchangeably in this article.

[0091] In some implementations, a UE 115 can be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some implementations, one or more UEs 115 in a group that are performing D2D communication can be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which can support various aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some implementations, one or more UEs 115 in such a group can be outside the coverage area 110 of the network entity 105 or otherwise may not be able or configured to receive transmissions from the network entity 105. In some implementations, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some implementations, the network entity 105 may facilitate scheduling of resources for D2D communication. In some other examples, D2D communication may be performed between UEs 115 without involving the network entity 105.

[0092] 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 a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing 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)) for routing packets or interconnecting 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 network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0093] The wireless communication system 100 can operate using one or more frequency bands that can range from 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features (which can be referred to as clusters), but these waves can penetrate structures sufficiently for a macro cell to provide service to a UE 115 located indoors. Communication using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) than communication using the smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0094] The wireless communication system 100 may also operate using the super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz (also known as the centimeter band), or the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some implementations, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices may be smaller and more closely spaced than UHF antennas. In some implementations, such techniques may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the frequency band usage specified across these frequency regions may vary by country or regulatory agency.

[0095] The wireless communication system 100 can utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating using unlicensed RF spectrum bands, devices such as the network entity 105 and the UE 115 can employ carrier sensing for conflict detection and avoidance. In some implementations, operations using unlicensed bands can be based on a carrier aggregation configuration in combination with component carriers operating using licensed bands (e.g., LAA). Operations using the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0096] A network entity 105 (e.g., a base station 140, a RU 170) or a 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 network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some implementations, the antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of multiple rows and columns of antenna ports that the network entity 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support RF beamforming for signals transmitted via the antenna ports.

[0097] The network entity 105 or the UE 115 may use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the 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 information 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 for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices.

[0098] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. The adjustments associated with each of these antenna elements can be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0099] The network entity 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations 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 network entity 105 along different directions. For example, the network entity 105 may transmit signals according to different sets of beamforming weights associated with different transmit directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as the network entity 105) or by a receiving device (such as the UE 115)) the beam direction for later transmission or reception by the network entity 105.

[0100] Some signals (such as data signals associated with a particular receiving device) may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115)). In some implementations, a beam direction associated with transmission along a single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted along different directions by network entity 105 and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0101] In some implementations, transmission by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from the network entity 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 set of beams across the system bandwidth or one or more subbands. The network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), CSI reference signals (CSI-RS)), which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port-selective codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

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

[0103] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly for communication via logical channels. The MAC layer may perform priority processing and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, the RRC layer may provide for the establishment, configuration, and maintenance of RRC connections between the UE 115 and the network entity 105 or the core network 130 for radio bearers supporting user plane data. The PHY layer may map transport channels to physical channels.

[0104] In some aspects, the wireless communication system 100 may support one or more beam management techniques. For example, the UE 115 may be in an RRC idle state (e.g., RRC_IDLE) or an RRC inactive state (e.g., RRC_INACTIVE) and may transmit or receive one or more tracking reference signals (TRS) prior to initial access. As part of the initial access, one or more devices (e.g., one or both of the UE 115 and the network entity 105) may perform synchronization signal block (SSB) beam sweeping, which may be associated with wide beam sweeping. In some aspects, the initial access may involve a contention-based random access (CBRA) procedure or a contention-free random access (CFRA) procedure associated with a random access channel (RACH) opportunity (RO) or the transmission or reception of a preamble or the transmission or reception of an SSB.

[0105] When a beam pair is established between two devices (e.g., between UE 115 and network entity 105), each device may perform beam management in an RRC connected state (e.g., RRC_CONNECTED). In some aspects, such beam management may include transmitting or receiving one or more SSBs, one or more CSI reference signals (CSI-RS), or one or more sounding reference signals (SRS), layer 1 (L1) reference signal received power (RSRP) reporting, and transmitting a configuration indicator (TCI) state configuration or indication. In some aspects, beam management (e.g., SSB or CSI-RS associated beam management) may be associated with a set of procedures P1, P2, and P3 designed for beam management when the devices are in a connected state. P1 may be associated with beam selection (e.g., the network entity 105 may scan beams, and the UE 115 may select one of the beams and report the selected beam to the network entity 105), P2 may be associated with beam refinement for the transmitter (e.g., the network entity 105 may refine the beam by scanning a narrower beam across a narrower range, and the UE 115 may select a narrower one of the narrower beams and report the selected narrower beam to the network entity 105), and P3 may be associated with beam refinement for the receiver (e.g., the network entity 105 may fix the beam, and the UE 115 may refine its receive beam). In some aspects, beam management (e.g., SRS-associated beam management) may be associated with a set of different uplink beam management procedures U1, U2, and U3, each of which may be associated with beam scanning.

[0106] Additionally or alternatively, beam management may include L1 signal to interference plus noise ratio (SINR) reporting and overhead and latency reduction. In some aspects, overhead and latency reduction may be associated with or otherwise relate to one or more component carrier (CC) group beam updates and lower latency uplink beam updates. Furthermore, in some aspects, beam management may involve beam measurements or reporting, or be associated with unified TCI states and L1 or layer 2 (L2) center mobility. For example, beam management procedures may include dynamic TCI state updates, uplink multi-panel selection, maximum permitted exposure (MPE) mitigation, or other techniques that facilitate further beam management latency reduction. Furthermore, some beam management procedures may include procedures associated with high speed train (HST) deployment, single frequency network (SFN) deployment, or multiple TRP deployment, or any combination thereof.

[0107] In some aspects, a device may measure, identify, or otherwise experience beam failure detection (BFD) based on measurements associated with beam management, and may perform one or more beam failure recovery procedures. BFD and beam failure recovery (BFR) may be performed for a primary cell (PCell), a primary secondary cell (PSCell), or a secondary cell (SCell). In addition, BFD and BFR may involve sending or receiving one or more BFD reference signals (BFD-RS), physical downlink control channel (PDCCH) block error rate (BLER) measurements, link recovery requests via scheduling requests (SRs), or MAC-CE-based BFR for SCells, or any combination thereof. In some cases, such as when a device cannot recover a failed beam pair link, the device may declare a radio link failure (RLF) and attempt to reestablish a connection via one or more initial establishment procedures.

[0108] Various devices of the wireless communication system 100 may support one or more AI or ML models associated with air interface prediction (e.g., prediction associated with wireless communication). In some deployments, for example, the devices may utilize or use AI or ML models for CSI feedback enhancement (e.g., for overhead reduction, higher accuracy, and more accurate prediction), beam management (e.g., beam prediction in the time or spatial domain for overhead and latency reduction and for higher beam selection accuracy), or positioning accuracy enhancement for different scenarios (e.g., scenarios associated with severe non-line-of-sight (NLOS) conditions).

[0109] In some cases, devices may utilize or use AI or ML models for specific use cases, such that the AI ​​or ML model approaches are sufficiently diverse to support various constraints on the level of collaboration between the UE 115 and the network entity 105. In addition, various devices may support one or both of the AI ​​or ML models or descriptions to identify common and specific characteristics for framework investigation or decision making. For example, a device may support models and descriptions for characterizing the lifecycle management of an AI or ML model, such as aspects related to model training, model deployment, model inference, model monitoring, or model updates.

[0110] In some deployments, the UE 115 or the network entity 105 may use AI or ML-based predictive beam management (e.g., for Uu beam management). For example, other beam management techniques may involve identification of beam quality or failure via measurement, which may be associated with greater power or overhead to achieve adequate performance. In addition, due to constraints on power or overhead, measurement-based beam management may be associated with limited accuracy, and latency and throughput may be adversely affected by beam recovery efforts. On the other hand, predictive beam management may be associated with power or overhead reduction, higher accuracy, lower latency, or higher throughput. For example, a predictive beam management process may enable a device to predict unmeasured beam quality (which may be associated with lower power consumption, lower overhead, or higher beam selection accuracy) and predict future beam blockage or failure (which may be associated with lower latency and greater throughput). Such predictive beam management may involve predictions in the spatial domain, time domain, frequency domain, or any combination thereof.

[0111] Some devices may specifically employ AI or ML to compensate for or address beam prediction, which can be a highly nonlinear problem in some deployments. For example, predicting future transmit beam quality may depend on the speed or trajectory of UE 115, the receive beam or beams to be used, or interference, among other examples, which may be difficult to model via some statistical signaling processing methods (e.g., statistical processing methods not based on AI or ML). In some deployments, there may be a tradeoff between performance and UE power consumption based on whether beam prediction is performed at UE 115 or at network entity 105. For example, to predict future downlink transmit beam quality, UE 115 may have more observations (e.g., via measurements) than network entity 105 (e.g., via UE feedback messages), and thus beam prediction at UE 115 may outperform beam prediction at network entity 105 (at the expense of consuming more UE power for prediction or inference processing tasks). Furthermore, model training may be performed at either UE 115 or network entity 105, and the decision between training locations may be associated with data collection effort compared to UE computational effort. For example, if training is performed by network entity 105, data may be collected via an air interface or via application layer methods. If training is performed by UE 115, UE 115 may perform additional UE computation or buffering tasks for model training and associated data storage.

[0112] AI or ML based spatial or time domain beam prediction or selection (e.g., for the downlink) may involve one or more of a variety of processes. For example, AI or ML based spatial or time domain beam prediction or selection may be used for initial access, secondary cell group (SCG) setup, serving beam refinement, link quality and interference adaptation (e.g., one or more parameters such as channel quality indicator (CQI) or precoding matrix indicator (PMI)), beam failure or blocking prediction, or RLF prediction. In some aspects, a specific one or more selection or prediction schemes may be used for each of such various processes. For example, codebook based spatial domain selection may be used for initial access, SCG setup, serving beam refinement, or link quality and interference adaptation. Non-codebook based spatial domain prediction may be used for serving beam refinement and link quality and interference adaptation. Additionally or alternatively, joint spatial and time domain beam prediction may be used for serving beam refinement, link quality and interference adaptation, beam failure or blocking prediction, or RLF failure prediction.

[0113] The codebook-based spatial domain selection may be associated with an input of a first set of beams (e.g., measurements of the first set of beams) and a predicted output (e.g., an output of an AI or ML model) of a second set of beams (e.g., a predicted set of beams). For interference at the network entity 105, the input may be associated with or include UE feedback and assistance information (e.g., history or location information). For inference at the UE 115, the input may be associated with or include UE measurements and assistance information (e.g., location information). The UE 115 may report or measure such measurement information using spatial or time domain compressed beam measurements. The codebook-based spatial domain selection may be associated with fewer beam measurements, which may result in reduced power at the measuring device (e.g., UE 115).

[0114] Non-codebook based spatial domain prediction may be associated with an input of a set of channels or beams (e.g., measurements associated with the set of channels or beams) and an output of a point direction, angle of departure (AoD), or angle of arrival (AoA). For inference at the network entity 105, the input may be associated with or include UE feedback and assistance information (e.g., history or location information). For inference at the UE 115, the input may be associated with or include UE measurements and assistance information (e.g., location information). Such reporting or measurement of such measurement information at the UE 115 may be facilitated via raw channel extraction. Non-codebook based spatial domain prediction may be associated with higher beam management accuracy without excessive beam scanning.

[0115] From the spatial domain to the spatial domain plus the time domain, the joint spatial and time domain beam prediction may be associated with time series inputs and outputs associated with both codebook-based spatial and time domain beam prediction and non-codebook-based spatial and time domain point direction, AoD, or AoA prediction. The time series inputs may include UE reports or measurements at the first time or measurement occasion (e.g., measurement occasion #0) of the UE at N th UE reports or measurements at a time or measurement opportunity (e.g., measurement opportunity #N). According to the joint spatial and time domain beam prediction, the time series input can be input to a first AI or ML model to obtain a first output of codebook-based spatial and time domain beam prediction, and can be input to a second AI or ML model to obtain a second output of non-codebook-based spatial and time domain point direction, AoD, or AoA prediction.

[0116] The prediction performance or cost may depend on whether the prediction is performed by the UE 115 or the network entity 105. If the prediction is performed at the network entity 105, the network entity 105 may use relatively more powerful computing power (e.g., compared to the UE 115), access to the distribution of L1 reports in terms of history and location, access to feedback or locations of other UEs 115, and awareness of the transmit beam shape and pointing direction to assist in beam prediction. In some deployments, the prediction performance at the network entity 105 may be balanced with other factors, such as only the strongest beam or beams may be reported by the UE 115, it may be difficult to know the receive beam used to derive L1 or CSI feedback, (all) UE feedback is quantized (and may potentially be omitted), and it may be difficult to know the orientation or rotation state of the UE 115. If beam prediction is performed at the UE 115, the UE 115 may use access to instantaneous and filtered measurements of a set of (e.g., all) beams, access to receive beams used to derive the measurements, raw or unquantized (all) measurements, and the ability to (at least partially) sense or predict its own orientation and rotation to assist in beam prediction. In some deployments, the prediction performance at the UE 115 may be balanced with other factors, such as the UE 115 may have relatively limited computational power, relatively limited knowledge of the historical distribution of L1 reports in the cell, difficulty accessing L1 or CSI feedback from other UEs 115, or relatively limited indication or knowledge of transmit beam shape or pointing.

[0117] In some deployments, for AI or ML-based beam management, devices of the wireless communication system 100 may support one or more beam management cases for characterization and baseline performance evaluation. A first beam management case, or BM-Case 1, may be associated with spatial domain downlink beam prediction for a set of beams A based on measurements of a set of beams B. A second beam management case, or BM-Case 2, may be associated with temporal downlink beam prediction for a set of beams A based on historical (e.g., previous) measurements of a set of beams B.

[0118] The beams of set A and set B may be in the same frequency range or in different frequency ranges. In some aspects, set B may be a subset of set A, where the number of beams in set A and set B may vary. In some other aspects, set A and set B may be different. For example, set A may include a set of relatively narrow beams, and set B may include a set of relatively wide beams. In such aspects, where the number of beams in set A and set B may vary, and there may be a defined quasi-co-location (QCL) relationship between the beams in set A and the beams in set B. Furthermore, various types or implementations of codebook constructions for set A and set B may be used without exceeding the scope of the present disclosure. In the context of such a set A of beams and a set B of beams, set A may be used for downlink beam prediction, and set B may be used for downlink beam measurement.

[0119] The UE 115 may receive control signaling from the network entity 105 that instructs, configures, activates, or triggers CSI reporting from the UE 115. For example, the UE 115 may be configured to send one or more synchronization signal (SS) / physical broadcast channel (PBCH) resource indicators (SSBRI) or CSI-RS resource indicators (CRI) and L1-RSRP or L1-SINR reports via one or more CSI reports. In some deployments, the UE 115 may receive (e.g., be configured with) ReportQuantity=ssb-Index-RSRP, ssb-Index-SINR, cri-RSRP, or cri-SINR for joint SSBRI / CRI and L1-RSRP / L1-SINR beam reporting. The UE 115 may report (e.g., send) the nrofReportedRS parameter (which may be RRC-configured and may be up to 2 or 4 depending on UE capabilities), which may be different for the SSBRI or CRI of each CSI-ReportConfig.

[0120] For L1-RSRP reporting, for the strongest SSBRI / CRI, 7 bits may be used to report RSRP in the range [-140, -44] dBm with 1 dBm steps. For the remaining SSBRI / CRI, 4 bits may be used to report differential RSRP (e.g., absolute or full maximum RSRP reported via 7 bits) in the range [0, -30] dB with 2 dB steps and with reference to the L1-RSRP of the strongest SSBRI / CRI. For the L1-RSRP of the strongest SSBRI / CRI, taking into account 2 7 = 128 but 140 - 44 + 1 = 97, there may be one or more invalid code points. In some systems, the mapping between the reported 7-bit code points and 4-bit code points and the actual measured RSRP values ​​may be defined by a specification such as a network specification.

[0121] Similarly, for L1-SINR reporting, for the strongest SSBRI / CRI, 7 bits may be used to report SINR in the range of [-23, 40] dB with a 0.5 dB step size. For the remaining SSBRI / CRI, 4 bits may be used to report differential SINR (e.g., the absolute or full maximum SINR reported via 7 bits) in the range of [0, -15] dB with a 1 dB step size and reference to the L1-SINR of the strongest SSBRI / CRI. For the strongest and remaining SSBRI / CRI, there may be no invalid code points, but SINR_0 may represent an SINR less than or equal to -23 dB for the strongest SSBRI / CRI, and DIFFSINR_15 may represent a ΔSINR less than or equal to -15 dB. In some systems, the mapping between the reported 7-bit code points and 4-bit code points and the actual measured SINR values ​​may be defined by specifications such as network specifications.

[0122] In some deployments, various devices in the wireless communication system 100 may support CSI reporting in an mTRP deployment. For example, when associated with an aperiodic resource configuration, such a device may extend the RRC parameter CSI-AssociatedReportConfigInfo to configure two CMR sets, each of which may be configured with or associated with corresponding QCL information. When associated with a periodic or semi-persistent resource configuration, the resource configuration may include two CMR sets. In some deployments, for some beam reporting options, a device may support fewer than or equal to two beams per group M.

[0123] In an mTRP deployment, the UE 115 may include a differential L1-RSRP report across all beam groups in the CSI report. In such a deployment, the UE 115 may include a 1-bit indicator of the CMR set associated with the maximum RSRP value across all groups in the CSI report (wherein it may be assumed that the "best" or strongest beam is in the first group). The 1-bit indicating the CMR set with the higher RSRP value may be set to "0" to indicate the first SSBRI / CRI from the first CMR set, and may be set to "1" to indicate the first SSBRI / CRI from the second CMR set. In addition, the uplink control information (UCI) payload partition may be set to 7 / 4 bits for the first / second SSBRI / CRI in the first beam group, and may be set to 4 bits for beams in other groups. Additional details of a UCI example where the number of groups N is equal to 2 and the number of beams per group M is equal to 2 are shown by the illustrated Table 1 below, where the CMR associated with the strongest or maximum RSRP measurement is example CMR#1, which may be indicated by the first beam group / pair.

[0124]

[0125] Table 1: Example CSI report in UCI

[0126] In mTRP scenarios, the UE 115 may lack a configured or known mechanism by which the UE 115 may report predicted beam pairs. For example, in scenarios where each TRP includes or is associated with a corresponding set A beam and set B beam, or where one of multiple TRPs includes or is associated with a set A beam and a set B beam, some L1 reporting signaling mechanisms may not be able to support predicted beam pair reporting. For example, in some mTRP L1 reporting configurations, a periodic or semi-persistent CSI reporting setting may be restricted to include two CMR sets, while an aperiodic CSI reporting setting may include multiple CMR sets, and an aperiodic CSI trigger state configuration may select two CMR sets for mTRP L1 reporting, but all such CSI reporting settings may not be able to include or indicate channel resources associated with beam prediction. As a result, UE 115 may not be able to provide beam prediction information in some deployment scenarios, such as mTRP deployment scenarios, which may limit the specific implementation options of beam prediction.

[0127] Thus, in some implementations, the UE 115 and the network entity 105 (e.g., one or more TRPs) may support Set A and Set B beam associations for mTRP deployments and one or more corresponding network signaling and UE reporting mechanisms. In some aspects, such signaling and reporting mechanisms may support beam prediction at the UE 115 and support mTRP L1 reports that can indicate predicted beam pairs for one or more TRPs. For example, the UE 115 and multiple TRPs may support CSI reporting settings that support information indicating Set A and Set B beam details and their associations, and L1 CSI reports that can be used to carry or indicate L1-RSRP / L1-SINR values ​​for a set of one or more predicted beams associated with Set B beams configured by the network (e.g., the network entity 105) in the CSI reporting settings. In some embodiments, the UE 115 and the network entity 105 (e.g., one or more TRPs) may support dynamically changing or updating set A beams and set B beams, and may support various MAC-CE or DCI-related signaling aspects for CSI reporting, while also supporting signaling mechanisms for supporting beam prediction via CSI reporting for mTRP scenarios associated with more than two TRPs (e.g., involving more than two TRPs).

[0128] Figure 2 An example of a wireless communication system 200 that supports CSI reporting for mTRP-based beam prediction according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may implement or may be implemented to implement aspects of the wireless communication system 100. For example, the wireless communication system 200 illustrates a system in which a UE 115, a TRP 205-a, and a TRP 205-b (which may be any of the systems described herein (including references thereto)) are connected. Figure 1 ) between the examples of corresponding devices described in the foregoing. In some specific implementations, UE 115, TRP 205-a, and TRP 205-b may support networking signaling and UE reporting mechanisms to facilitate or support indication of predicted signal strength associated with channel resources of one or more CPR sets 215 based on measurements of channel resources of one or more CMR sets 210. In other words, UE 115, TRP 205-a, and TRP 205-b may support one or more configuration- or signaling-based mechanisms, according to which UE 115, TRP 205-a, and TRP 205-b may support set A and set B beam associations and group-based L1 reporting (e.g., group-based L1-RSRP / L1-SINR reporting) for mTRP beam prediction. As described herein, any one or more of UE 115, TRP 205-a, and TRP 205-b may be referred to or understood as a network node.

[0129] As described herein, a set of beams A may be predicted and a set of beams B may be actually measured. For example, TRP 205-a and TRP 205-b may transmit one or more reference signals using each beam in a set of beams B via channel resources of CMR set 210-a and CMR set 210-b, respectively, where the set of beams B may include a set of beams 220-a from TRP 205-a and a set of beams 220-b from TRP 205-b. Furthermore, UE 115 may predict measurement information (e.g., signal strength such as L1-RSRP or L1-SINR measurements) for each beam in at least a subset of the set A beams associated with each of TRP 205-a and TRP 205-b. Set A beams may include a set of beams 225-a from TRP 205-a and a set of beams 225-b from TRP 205-b, which may be associated with channel resources of CPR set 215-a and CPR set 215-b, respectively. In other words, the set of beams 220-a may be associated with CMR set 210-a, the set of beams 220-b may be associated with CMR set 210-b, the set of beams 225-a may be associated with CPR set 215-a, and the set of beams 225-b may be associated with CPR set 215-b. In some aspects, the set of beams 220 (e.g., the set of beams 220-a and the set of beams 220-b) may be relatively wide beams, and the set of beams 225 (e.g., the set of beams 225-a and the set of beams 225-b) may be relatively narrow beams.

[0130] CMR set 210 (e.g., either or both of CMR set 210-a and CMR set 210-b) may be referred to herein as a channel resource set for channel measurement, and CPR set 215 (e.g., either or both of CPR set 215-a and CPR set 215-b) may be referred to herein as a channel resource set for beam prediction. CMR set 210-a and CPR set 215-a may be associated with each other, which may refer to how UE 115 uses measurements of one or more channel resources of CMR set 210-a to predict measurements of one or more channel resources of CPR set 215-a. Similarly, CMR set 210-b and CPR set 215-b may be associated with each other, which may refer to how UE 115 uses measurements of one or more channel resources of CMR set 210-b to predict measurements of one or more channel resources of CPR set 215-b. Furthermore, although described herein as a CPR set 215, the channel resources of the CPR set 215 may additionally or alternatively be part of a CMR set, where such a CMR set may be configured, indicated, or defined for or associated with a channel or beam prediction function.

[0131] The UE 115 may receive configuration information associated with the CMR set 210-a and the CMR set 210-b via the CSI reporting setup 230, and potentially also receive information indicating an association between the CMR set 210 and the CPR set 215. The UE 115 may receive signaling associated with the CSI reporting setup 230 via the CSI reporting setup information 235, which may be associated with two or more CMR sets 210 (e.g., CMR set 210-a and CMR set 210-b) and two or more CPR sets 215 (e.g., CPR set 215-a and CPR set 215-b) for channel measurement (e.g., including future indication indicating the two or more CMR sets for channel measurement or otherwise enabling the two or more CMR sets for channel measurement). According to the CSI report configuration information 235, the CMR set 210-a may include N1 CMRs (e.g., SSB or non-zero power (NZP)-CSI-RS), and the CMR set 210-b may include N2 CMRs, where N1 and N2 may be the same or different. The CPR set 215-a may include M1 CPRs, and the CPR set 215-b may include M2 ​​CPRs, where M1 and M2 may be the same or different.

[0132] In some implementations, the signaling associated with the CSI report setup 230 (e.g., CSI report setup information 235) may depend on whether the CSI report setup 230 is associated with periodic, semi-persistent, or aperiodic CSI reports 245. For a CSI report setup 230 associated with any of periodic, semi-persistent, or aperiodic CSI reports 245, the CMR set 210-a, CMR set 210-b, CPR set 215-a, and CPR set 215-b may be directly configured by the CSI report setup 230 (e.g., all channel resource sets may be configured by the CSI report setup 230, which may be understood as a single CSI report setup message and equivalently referred to as a CSI resource setup). Alternatively, the CMR set 210-a and the CMR set 210-b may be configured by a first CSI report setup message, and the CPR set 215-a and the CPR set 215-b may be configured by a second CSI report setup message, which may be referred to as a CSI prediction setup. Such a second CSI report setup message may configure or indicate a channel resource or a set of channel resources to be used for beam or channel prediction (eg, as opposed to being used for beam or channel measurement).

[0133] For a CSI report setting 230 associated with a semi-persistent CSI report 245, the CSI report setting 230 may configure multiple (e.g., more than two) {CMR set, CPR set} pairs, and the MAC-CE that activates the semi-persistent CSI report 245 may further activate two {CMR set, CPR set} pairs for channel measurement and beam prediction. As described herein, a {CMR set, CPR set} pair may refer to a CMR set 210 and a CPR set 215 that are paired or associated with each other. For a CSI report setting 230 associated with an aperiodic CSI report 245, the CSI report setting 230 may configure multiple (e.g., more than two) {CMR set, CPR set} pairs, and the aperiodic CSI trigger state configuration associated with the CSI report setting 230 (e.g., a message that triggers the aperiodic CSI report 245, such as a DCI message) may further select two {CMR set, CPR set} pairs for channel measurement and beam prediction.

[0134] In some implementations, the UE 115, TRP 205-a, and TRP 205-b can support signaling associated with the CSI reporting settings 230 that facilitates conveying UE capabilities on a simultaneously configured or activated number of CSI reports 245 associated with beam prediction (e.g., CSI reports 245 that carry predicted signal strengths associated with one or more channel resources of one or more CPR sets 215). In other words, the UE 115 can report the capabilities of the UE 115 on a maximum (e.g., upper limit) number of CSI reports 245 for which this type of configuration or indication (e.g., configuration or indication related to one or more CPR sets 215 in addition to one or more CMR sets 210) can be simultaneously configured or activated at the UE 115. The configured CSI reports 245 may refer to a plurality of CSI reporting settings configured via RRC signaling, and the activated CSI reports 245 may refer to how many RRCs are configured for periodic CSI reporting, how many MAC-CEs are activated for semi-persistent CSI reporting, or how many DCIs are triggered for aperiodic CSI reporting. In some implementations, the UE 115 may perform such capability reporting by separately reporting capabilities associated with periodic, semi-persistent, and aperiodic CSI reporting 245, since each of the periodic, semi-persistent, and aperiodic CSI reporting 245 may be associated with a different type of indication scheme.

[0135] In some aspects, an additional information element (IE) may be included in the CSI report setup 230. Such additional IE may be referred to as beamPredictionmTRP and may indicate that the CSI report setup 230 is a type of CSI report setup 230 that is dedicated to the mTRP beam prediction use case. In such aspects, the UE capability indication reported by the UE 115 may indicate the number (e.g., a maximum or upper limit number) of CSI reports 245 that include such additional IE. Additionally or alternatively, the number of CMRs / CPRs addressed in the L1 report (e.g., CSI report 245) and the corresponding measured or predicted signal strengths (e.g., L1-RSRP / L1-SINR) may be configured or indicated by the CSI report setup 230. In other words, the TRP 205-a or TRP 205-b may indicate via the CSI report setup information 235 how many CMRs and CPRs (and the corresponding measured signal strengths or predicted signal strengths, respectively) are to be included in the CSI report 245.

[0136] In some implementations, the UE 115, the TRP 205-a, and the TRP 205-b may exchange signaling that supports or indicates a beam association between the CMR set 210 and the CPR set 215. For example, the UE 115 may receive signaling from the network entity 105 (e.g., one of the TRP 205-a or TRP 205-b, or a separate entity associated with one or both of the TRP 205-a and TRP 205-b) indicating a beam shape correspondence between the CMR and CPR in each pair {CMR set, CPR set}. In other words, the UE 115, the TRP 205-a, and the TRP 205-b may associate the set A beams (which may be associated with the CPR set 215) and the set B beams (which may be associated with the CMR set 210) to help the UE 115 predict beams in the spatial domain or the time domain. The beam shape correspondence information may include information explicitly indicating the beam shapes or directions used for the set A beam and the set B beam, or may include information indicating relative beam directions or widths of the set A beam and the set B beam. In some aspects, the information indicating the beam shape correspondence information may depend on whether the CSI reporting configuration 230 is associated with periodic, semi-persistent, or aperiodic CSI reporting 245.

[0137] For a CSI reporting configuration 230 associated with any of periodic, semi-persistent, or aperiodic CSI reporting 245, corresponding information may be directly indicated for each pair of {CMR set, CPR set}. For example, the corresponding information may be indicated via CSI reporting configuration information 235 or via other control signaling from one or both of TRP 205-a and TRP 205-b. For a CSI reporting configuration 230 associated with semi-persistent CSI reporting 245, the corresponding information may be indicated by an activation MAC-CE (which may also optionally indicate the selection of each pair of {CMR set, CPR set}). For example, the activation MAC-CE may indicate corresponding information for each pair of {CMR set, CPR set} activated by the MAC-CE (e.g., each pair of {CMR set, CPR set} actually to be used among the configured {CMR set, CPR set} pairs). For the CSI reporting setting 230 associated with the aperiodic CSI reporting 245, the aperiodic CSI triggering state configuration associated with the CSI reporting setting 230 (which may also optionally indicate the selection of respective pairs of {CMR set, CPR set}) may indicate corresponding information associated with each selected or triggered {CMR set, CPR set} pair (e.g., such that corresponding information is indicated for each pair of {CMR set, CPR set} that is actually to be used in the configured respective {CMR set, CPR set} pairs).

[0138] The beam shape association or correspondence information may be indicated explicitly or differentially (e.g., via explicit or differential association). In some implementations, the beam shape correspondence information may explicitly indicate beam spot direction information and beam width information for the CMR set 210 and the CPR set 215. Additionally or alternatively, the beam shape correspondence information may implicitly indicate a difference in beam spot direction or beam width between resources in the CMR set 210 and the CPR set 215. Additionally or alternatively, the beam shape correspondence information may indicate a QCL relationship between resources in the CMR set 210 and the CPR set 215. In some implementations, the UE 115 may receive an indication or configuration of a serving cell-specific beamforming codebook including a plurality of selections of beam pointing directions or beam widths, and in such implementations, the beam shape correspondence information may indicate code points in the codebook for corresponding resources included in the CMR set 210 and the CPR set 215 to indicate the correspondence information.

[0139] Based on receiving the information indicating the CSI report setting 230, the indication of the association or pairing between the CMR set 210 and the CPR set 215, and the beam shape association or correspondence information between the {CMR set, CPR set} pair, the UE 115 may receive one or more reference signals 240 from the TRP 205-a and the TRP 205-b via the channel resources of the CMR set 210-a and the CMR set 210-b, respectively, and measure a set of signal strengths of the received reference signals 240. In some implementations, the TRP 205-a may transmit the set of reference signals 240 using beam 220-a via the channel resources of the CMR set 210-a, and the TRP 205-b may transmit the set of reference signals 240 using beam 220-b via the channel resources of the CMR set 210-b.

[0140] UE 115 may use channel measurement information associated with CMR set 210-a and CMR set 210-b (as obtained via measurements of reference signal 240) to at least predict signal strengths associated with one or more CPRs in CPR set 215-a or CPR set 215-b. In other words, for example, UE 115 may use measurements of beam 220-a transmitted via CMR set 210-a to predict signal strengths for a set of beams 225-a associated with CPR set 215-a, and may use measurements of beam 220-b transmitted via CMR set 210-b to predict signal strengths for a set of beams 225-b associated with CPR set 215-b. In some aspects, UE 115 may use an AI or ML model or algorithm to predict signal strengths for the set of beams 225-a and the set of beams 225-b.

[0141] In some implementations, the UE 115 may predict the signal strength (e.g., L1-RSRP or L1-SINR) associated with a paired CPR. A CPR pair may refer to two CPRs, each associated with a different CPR set 215, that the UE 115 may group or pair together (e.g., indicate as a pair) via the CSI report 245, wherein the pairing of the two CPRs may imply or indicate to the TRP 205-a and the TRP 205-b that the UE 115 is capable of receiving signaling simultaneously via beams associated with the two CPRs. In other words, the UE 115 may select a first CPR in the CPR pair from the CPR set 215-a and a second CPR in the CPR pair from the CPR set 215-b, such that the UE 115 is capable of receiving simultaneously via the first CPR and the second CPR in the CPR pair. In some implementations, the UE 115 may perform predictions of signal strengths (e.g., L1-RSRP / L1-SINR) for the CPRs in the CPR set 215-a and the CPR set 215-b based at least in part on channel measurements associated with the CMRs in the CMR set 210-a and the CMR set 210-b, respectively. In other words, the UE 115 may predict the signal strengths of the CPRs in the CPR set 215-a based on the measurements of the CMRs in the CMR set 210-a, and may predict the signal strengths of the CPRs in the CPR set 215-b based on the measurements of the CMRs in the CMR set 210-b.

[0142] Based on obtaining the measured signal strengths of at least a subset of the CMRs of CMR set 210-a and CMR set 210-b and the predicted signal strengths of at least a subset of the CPRs of CPR set 215-a and CPR set 215-b, UE 115 may report one or more pairs of predicted pairwise signal strengths (e.g., L1-RSRP / L1-SINR) and corresponding CPR identifiers associated with the respective CPR sets 215 via CSI report 245 associated with CSI reporting settings 230. In some implementations, UE 115 may also report the CPR set identifier associated with the strongest predicted signal strength in the set of (e.g., all) predicted pairwise signal strengths. Additionally, in some implementations, UE 115 may include group-based mTRP reports associated with CMR set 210-a and CMR set 210-b in CSI report 245.

[0143] UE 115, TRP 205-a, and TRP 205-b may support various quantization schemes or formatting schemes for the predicted and measured signal strengths indicated by UE 115 via CSI report 245. In some implementations, UE 115, TRP 205-a, and TRP 205-b may use a first quantization scheme or format associated with absolutely indicating the signal strength of one report and differentially indicating the signal strengths of the remaining reports relative to the absolutely indicated signal strength. In such implementations, the absolutely indicated signal strength may be the maximum signal strength among the reported signal strengths and may be associated with CMR set 210 or CPR set 215. In some other implementations, UE 115, TRP 205-a, and TRP 205-b may use a second quantization scheme or format associated with absolutely indicating the signal strength of one report for each of CMR set 210 and CPR set 215 and differentially indicating the signal strengths of the remaining reports relative to the absolutely indicated signal strength.

[0144] In an implementation where UE 115, TRP 205-a, and TRP 205-b employ the first quantization scheme, UE 115 may include a bit for indicating whether the strongest (predicted or measured) signal strength is from CPR set 215 or from CMR set 210. UE 115 may also report the CMR set identifier or CPR set identifier associated with the strongest measured or predicted signal strength. Additionally, UE 115 may report paired signal strengths, wherein the pair including or associated with the strongest signal strength may be reported first (e.g., first in order), and wherein the strongest signal strength and the strongest signal strength associated with the CMR identifier or CPR identifier may be reported before the paired CMR or CPR.

[0145] In such implementations, the UE 115 may report the strongest signal strength absolutely via the X1 bit (e.g., 7 bits) and may report the remaining signal strength differentially with reference to (e.g., relative to) the strongest signal strength via the X2 bit (e.g., 4 bits). In some aspects, the number of bits included for reporting the CMR identifier or CPR identifier depends on the total number of CMRs and CPRs included in the corresponding CMR set and CPR set. In some implementations, the UE 115, TRP 205-a, and TRP 205-b may expect the strongest signal strength to be associated with the CPR set 215, depending on configuration or default interpretation. Additional details related to such a first quantization scheme are illustrated by Tables 2.1 and 2.2 shown below. A combination or concatenation of Tables 2.1 and 2.2 may illustrate the CSI report 245 in an example in which both the measured signal strength and the predicted signal strength are carried in the CSI report 245.

[0149]

[0150] Table 2.2: Example Part 2 of CSI Report 245

[0151] In a specific implementation where UE 115, TRP 205-a, and TRP 205-b employ the second quantization scheme, UE 115 may separately report the signal strengths of CMR and CPR (e.g., L1-RSRP or L1-SINR). For example, UE 115 may separately report {CMR set ID, CPR set ID} including the strongest {measured, predicted} signal strength. In other words, UE 115 may report the strongest signal strengths associated with CMR and CPR, respectively, via absolute indications. Similar to the mTRP L1 reporting architecture of the first quantization scheme, UE 115 may format other aspects of CSI report 245, except that UE 115 may separately report two sets of information for measured and predicted signal strengths and CMR ID+CPR ID.

[0152] In other words, the UE 115 may indicate a first signal strength associated with the CPR in absolute terms and may indicate a signal strength of each CPR in the remaining CPR set reported via the CSI report 245 differentially relative to the first signal strength, and may indicate a second signal strength associated with the reported CMR in absolute terms and may indicate a signal strength of each CMR in the remaining CMR set reported via the CSI report differentially relative to the second signal strength. In such an example, the first signal strength may be the maximum CPR signal strength among the reported CPR signal strengths, and the second signal strength may be the maximum reported CMR signal strength among the reported CMR signal strengths. Furthermore, the number of bits that the UE 115 may use to report a CMR ID or CPR ID may depend on the number of CMRs and CPRs included in the respective CMR set and CPR set.

[0153] In some other implementations, the UE 115 may use different quantization schemes for the measured and predicted signal strengths. For example, the quantization scheme (which may refer to the number of bits used for absolute signal strength quantization and differential signal strength quantization and the associated quantization step size and range) may be different for the measured and predicted signal strengths. In other words, the UE 115 may use a first quantization scheme for the measured signal strength and a second quantization scheme for the predicted signal strength. In such implementations, the UE 115, the TRP 205-a, and the TRP 205-b may support multiple quantization options (e.g., according to configuration signaling or network specifications), and the network entity 105 may indicate two options to the UE 115, one for the measured signal strength and one for the predicted signal strength.

[0154] In one example, UE 115 may use a different number of bits for each absolute or differential signal strength indication for measured signal strength and predicted signal strength. In some aspects, for example, UE 115 may use X1 bits for an absolute indication of measured or predicted signal strength, may use X2 bits for a differential indication of measured signal strength, and may use X3 bits for a differential indication of predicted signal strength. In some aspects, X2 may be greater than X3 (e.g., X2=4 and X3=4) because predicted signal strength may be associated with a relatively lower confidence level than measured signal strength, such that a lower accuracy for lower signaling overhead may be relatively more appropriate for predicted signal strength than for measured signal strength.

[0155] In some implementations, the UE 115, TRP 205-a, and TRP 205-b may support reporting of confidence levels associated with a signal strength prediction made by the UE 115 that is associated with a reported CPR. In some aspects, the UE 115 may report a standard deviation or variance associated with the predicted signal strength (which may be normalized or non-normalized). Additionally or alternatively, the UE 115 may report a confidence level specifically for the strongest reported predicted signal strength, or may separately report confidence levels associated with a set of (e.g., all) reported predicted signal strengths (such that each reported predicted signal strength is associated with a corresponding confidence level). Additionally or alternatively, the UE 115 may report a single confidence level associated with a set of (e.g., all) reported predicted signal strengths, thereby jointly considering the set of (e.g., all) reported predicted signal strengths.

[0156] Furthermore, although described in the context of an example including two CMR sets 210 and two CPR sets 215, the UE 115, TRP 205-a, and TRP 205-b may employ the described techniques in scenarios where the UE 115 may report information associated with more than two CMR sets 210 or more than two CPR sets 215. In other words, the UE 115, TRP 205-a, and TRP 205-b may communicate configuration information via CSI report setup information 235, transmit or receive reference signals 240, and communicate measurement information and prediction information via CSI reports 245 associated with more than two {CMR set, CPR set} pairs. In such implementations, the number of bits that the UE 115 may include in the CSI report 245 may depend on the number of {CMR set, CPR set} pairs for which the UE 115 includes measurement information and prediction information. For example, the number of bits may increase as the number of {CMR set, CPR set} pairs reported increases, and the number of bits used may be determined or selected similarly to how the number of bits used to indicate a CMR or CPR ID is determined or selected.

[0157] Furthermore, although illustrated and described in the context of TRP 205-a being associated with CMR set 210-a and CPR set 215-a, and TRP 205-b being associated with CMR set 210-b and CPR set 215-b, the described techniques may also be applicable to scenarios in which a subset of one or more CMR sets 210 is associated with CPR set 215. For example, in some implementations, only a subset of one or more CMR sets 210 may be paired with CPR set 215, while the remaining CMR sets 210 may not be paired with a CPR set. In one example, CMR set 210-a may be associated with CPR set 215-a, and CMR set 210-b may not be associated with CPR set 215.

[0158] Based on one or more signaling mechanisms, the UE 115, the TRP 205-a, and the TRP 205-b may support such variations in whether a CMR set 210 is paired with a CPR set 215. In some implementations, each CMR set 210 may be initially paired with a CPR set 215 in a CSI reporting setup 230 (e.g., an RRC-configured CSI reporting setup 230), and a MAC-CE that activates semi-persistent CSI reporting 245 or aperiodic CSI trigger state configuration may disable one or more paired CPR sets 215 for a specified (e.g., indicated) one or more CMR sets 210. In such implementations, the UE 115 may receive an indication of the initial pairing of each CMR set 210 to a CPR set 215 from at least one of the TRP 205-a or the TRP 205-b via CSI reporting setup information 235.

[0159] In some other implementations, each CMR set 210 may not initially be paired with a CPR set 215 in the CSI reporting settings 230, and the MAC-CE that activates the semi-persistent CSI reporting 245 or the aperiodic CSI triggering state configuration may indicate one or more CPR set IDs that are paired with the corresponding one or more CMR sets 210. In such implementations, the CSI reporting setting information 235 may not indicate the association between the CMR sets 210 and the CPR sets 215, and instead, an additional signal (e.g., an activation MAC-CE or a triggering message such as a DCI message) may indicate the association (e.g., pairing) between the one or more CMR sets 210 and the one or more CPR sets 215. Furthermore, in such implementations, the activation MAC-CE or the aperiodic CSI triggering state may indicate beam shape correspondence information for each indicated {CMR set, CPR set} pair.

[0160] In some implementations, one or more CMR sets 210 in a CSI reporting setup 230 may not be paired with a corresponding CPR set 215. In some aspects, the UE 115, the TRP 205-a, and the TRP 205-b may selectively configure (or not configure) or selectively enable (or disable) association or pairing for a given CMR set 210 based on the number of narrow beams associated with the corresponding TRP 205. For example, if the set of beams 225-a of the TRP 205-a is relatively large (e.g., includes more than a threshold number of beams), the TRP 205-a and the UE 115 may support association or pairing between the CMR set 210-a and the CPR set 215-a. If the set of beams 225-b of the TRP 205-b is relatively small (e.g., includes less than a threshold number of beams), the TRP 205-b and the UE 115 may refrain from supporting association or pairing for the CMR set 210-b. Thus, UE 115, TRP 205-a and TRP 205-b can selectively configure or enable association or pairing with the corresponding CMR set 210 (to configure or enable prediction of a second set of associated or paired beams 225) based on the relative signaling overhead and measurement-related power consumption costs at UE 115.

[0161] In such an implementation where UE 115, TRP 205-a, and TRP 205-b use a CSI reporting setup 230 in which at least one CMR set 210 is not associated or paired with a corresponding CPR set 215, UE 115 may report a mix of measured and predicted signal strength pairs or groups, and UE 115 may report these pairs or groups so that UE 115 may be able to simultaneously receive via the reported paired or grouped CMRs or CPRs. In such an implementation, as in an implementation where each CMR set 210 is associated or paired with a corresponding CPR set 215, UE 115 may use the same quantization scheme for the measured and predicted signal strengths, or may use different quantization schemes for the measured and predicted signal strengths.

[0162] Figure 3 An example of a channel resource set timeline 300 that supports CSI reporting for mTRP-based beam prediction according to one or more aspects of the present disclosure is illustrated. The channel resource set timeline 300 may implement or be implemented to facilitate or achieve aspects of the wireless communication system 100 or the wireless communication system 200. For example, the channel resource set timeline 300 illustrates a timeline or periodicity of a CMR set 210 that may be associated with a set of beams 220 and a CPR set 215 that may be associated with a set of beams 225. Figure 3 In the example of FIG. 2 , the CMR set 210 and the CPR set 215 may be paired or associated with each other.

[0163] In some implementations, the TRP 205 (e.g., Figure 2 The TRP 205-a or TRP 205-b illustrated and described with reference to the figure may transmit a set of one or more reference signals using a set of beams 220 via the channel resources of the CMR set 210, and the UE 115 (e.g., Figure 1 and Figure 2 The UE 115 (as illustrated and described with reference to these figures) can use measurements of the channel resources of the CMR set 210 to predict signal strengths associated with a set of beams 225, each of which can be associated with channel resources of the CPR set 215. In some implementations, the CPR set 215 can include a set of actual resources. For example, the channel resources included in the CPR set 215 can also be CMRs (e.g., NZP-CSI-RS or SSB resources) associated with a relatively longer periodicity than the CMRs of the CMR set 210. Thus, the TRP 205 can use the CPRs of the CPR set 215 to transmit one or more reference signals via the set of beams 225, but with a greater periodicity than the TRP 205 can use to transmit reference signals via the set of beams 220 using the CMRs of the CMR set 210.

[0164] Figure 4 An example of a channel resource set timeline 400 that supports CSI reporting for mTRP-based beam prediction according to one or more aspects of the present disclosure is illustrated. The channel resource set timeline 400 may implement or be implemented to facilitate or implement aspects of the wireless communication system 100 or the wireless communication system 200. For example, the channel resource set timeline 300 illustrates a timeline or periodicity of a CMR set 210 that may be associated with a set of beams 220 and a CPR set 215 that may be associated with a set of beams 225. Figure 4 In the example of FIG. 2 , the CMR set 210 and the CPR set 215 may be paired or associated with each other.

[0165] In some implementations, the TRP 205 (e.g., Figure 2 The TRP 205-a or TRP 205-b illustrated and described with reference to the figure may transmit a set of one or more reference signals using a set of beams 220 via the channel resources of the CMR set 210, and the UE 115 (e.g., Figure 1 and Figure 2 The UE 115 illustrated and described with reference to these figures may use measurements of the channel resources of the CMR set 210 to predict signal strengths associated with a set of beams 225, each of which may be associated with channel resources of the CPR set 215. In some implementations, the CPR set 215 may include a set of virtual resources. For example, the resources included in the CPR set 215 may be virtual resources that are not expected to be transmitted by the TRP 205 and are not expected to be received by the UE 115. In such implementations, the CMR set 210 and the CPR set 215 may be associated with the same periodicity because the periodicity of the CPR set 215 may not affect signaling overhead or measurement-related power consumption costs at the UE 115 because the CPR set 215 includes virtual resources that are not actually transmitted or received.

[0166] Figure 5 An example of a process flow 500 for supporting CSI reporting for mTRP-based beam prediction according to one or more aspects of the present disclosure is illustrated. The process flow 500 may implement or be implemented to facilitate or achieve aspects of the wireless communication system 100, the wireless communication system 200, the channel resource set timeline 300, and the channel resource set timeline 400. For example, the process flow 500 illustrates communications between the UE 115, the TRP 205-a, and the TRP 205-b, which may be as described by Figures 1 to 4Examples of corresponding devices illustrated and described with reference to these figures. In some deployments, TRP 205-a and TRP 205-b may be associated with network entity 105 (e.g., associated with a component of the network entity or controlled by the network entity). In some specific implementations, UE 115, TRP 205-a, and TRP 205-b may support one or more configuration- or signaling-based mechanisms, according to which UE 115, TRP 205-a, and TRP 205-b may support Set A and Set B beam association and group-based L1 reporting for mTRP beam prediction (e.g., group-based L1-RSRP / L1-SINR reporting). As described herein, any one or more of UE 115, TRP 205-a, and TRP 205-b may be referred to or understood as a network node.

[0167] In the following description of process flow 500, operations (such as reporting or providing) may be performed in a different order than shown, or operations performed by the example device may be performed in a different order or at different times. Some operations may also be excluded from process flow 500, or other operations may be added to process flow 500. Furthermore, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations may actually occur simultaneously.

[0168] At 505, the UE 115 may transmit capability information indicating an upper limit on the number of CSI reports associated with beam prediction that the UE 115 can simultaneously configure or activate. In some aspects, the number of channel-resource pairs included in the CSI report may be associated with (e.g., dependent on) the upper limit on the number of CSI reports that the UE 115 can perform. The UE 115 may transmit the capability information to the TRP 205-a or TRP 205-b, or to a network entity 105 associated with the TRP 205-a and the TRP 205-b, via various types of uplink signaling, including uplink control information (UCI), MAC-CE, uplink data channel, uplink shared channel, or random access channel.

[0169] At 510, UE 115 may receive CSI report configuration information, which may indicate CSI report configurations such as Figure 2 In some implementations, the CSI report setting information may be associated with a first channel resource set for channel measurement and a second channel resource set for channel measurement. As described herein, such a channel resource set for channel measurement may be an example of a CMR set, such as a set of CMRs, such as a set of CMRs, such as a set of CMRs, and ...SI reports. Figure 22. In some implementations, the first channel resource set may be associated with a third channel resource set for beam prediction, and the second channel resource set may be associated with a fourth channel resource set for beam prediction. As described herein, such channel resource sets for beam prediction may be examples of CPR sets, such as those provided by Figure 2 CPR set 215 - a and CPR set 215 - b are shown and described with reference to the figure.

[0170] UE 115 may receive CSI report configuration information from TRP 205-a, TRP 205-b, or a network entity 105 associated with TRP 205-a and TRP 205-b via one or more messages. In implementations where UE 115 receives CSI report configuration information via multiple messages, each of the multiple messages may include a different portion of the CSI report configuration information. In such implementations, the multiple messages may refer to separately signaled messages or different IEs or parameters each carrying a different portion of the CSI report configuration information. In some aspects, UE 115 may receive the CSI report configuration information via RRC signaling.

[0171] At 515, in some implementations, the UE 115 may receive a MAC-CE or trigger message (e.g., a DCI message) associated with activating or triggering a CSI reporting setup. In some implementations, the MAC-CE or trigger message may indicate activation or selection of a first channel resource set pair comprising a first channel resource set and a third channel resource set and a second channel resource set pair comprising a second channel resource set and a fourth channel resource set. In other words, in such implementations, the MAC-CE or trigger message may indicate an association or pairing between a CMR and a CPR. In some aspects, the MAC-CE or trigger message may also indicate the third channel resource set and the fourth channel resource set. The UE 115 may receive the MAC-CE or trigger message from a TRP 205-a, a TRP 205-b, or a network entity 105 associated with the TRP 205-a and the TRP 205-b.

[0172] At 520 and 525, UE 115 may receive a set of one or more reference signals from each of TRP 205-a and TRP 205-b via channel resources of the first channel resource set and the second channel resource set, respectively (e.g., if the first channel resource set is associated with TRP 205-a and the second channel resource set is associated with TRP 205-b). UE 115 may use the reference signals received from TRP 205-a and TRP 205-b to perform or otherwise obtain channel measurements on the channel resources of the first channel resource set and the second channel resource set. For example, UE 115 may obtain a set of L1-RSRP values ​​or L1-SINR values ​​associated with the channel resources of the first channel resource set and the second channel resource set.

[0173] At 530, UE 115 may predict a respective signal strength associated with each respective channel resource of one or more channel resource pairs based on the set of channel measurements associated with channel resources of the first and second channel resource sets, wherein each of the one or more channel resource pairs includes a respective first channel resource from a third channel resource set and a respective second channel resource from a fourth channel resource set. In other words, UE 115 may predict a signal strength associated with a paired CPR.

[0174] At 535, UE 115 may transmit a CSI report indicating a predicted signal strength for at least one of the one or more channel resource pairs. In some implementations, UE 115 may additionally include in the CSI report measured signal strengths associated with one or more second channel resource pairs, wherein each of the one or more second channel resource pairs includes a corresponding first channel resource from the first set of channel resources and a corresponding second channel resource from the second set of channel resources. In some implementations, UE 115 may use one or more quantization schemes associated with the measured and predicted signal strengths included in the CSI report. UE 115 may transmit the CSI report to TRP 205-a, TRP 205-b, or a network entity 105 associated with TRP 205-a and TRP 205-b.

[0175] At 540, the UE 115 may receive control signaling associated with which directional beams will be used to communicate with one or both of the TRP 205-a and the TRP 205-b. For example, the UE 115 may receive information indicating which beams the TRP 205-a or the TRP 205-b will use to communicate with the UE 115 based on a CSI report (e.g., based on predicted signal strength). Additionally or alternatively, the control signaling may indicate which beams the UE 115 may use to communicate with the TRP 205-a or the TRP 205-b based on a CSI report (e.g., based on predicted signal strength). The UE 115 may receive the control signaling from the TRP 205-a, the TRP 205-b, or a network entity 105 associated with the TRP 205-a and the TRP 205-b via a DCI, a MAC-CE, a downlink control channel, a downlink data channel, or a downlink shared channel.

[0176] At 545, UE 115 may communicate with TRP 205-a and TRP 205-b according to the control signaling and based on the CSI report. For example, UE 115 may receive downlink signaling from TRP 205-a and TRP 205-b via a TRP beam that UE 115 predicts has a relatively high signal strength in the CSI report or a beam otherwise indicated via control signaling. UE 115 may communicate with TRP 205-a and TRP 205-b via one or more control channels, data channels, or shared channels.
