Techniques for efficient signaling for beam prediction

Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive first control information indicating generation of a channel state information (CSI) report, where the CSI report is used for measurement results related to a first set of beams. The UE may receive second control information indicating a channel measurement resource (CMR) and relationship information between one or more second sets of beams and the CMR. The UE may measure the CMR to obtain a set of measurements, wherein one CMR is determined based on the relationship information. Based on the measurement of the CMR, the UE may determine a set of predictors, where each predictor in the set of predictors is associated with one beam in the first set of beams. The UE may send the CSI report with reporting results, the reporting results including at least a subset set of prediction results.

Description

Technical Field

[0001] The following relates to wireless communications, including techniques for efficient signaling for beam prediction. Background Art

[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 may be able to 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 techniques relate to improved methods, systems, devices, and apparatuses for supporting efficient signaling techniques for beam prediction. For example, the described techniques allow a network entity to indicate relationship information between one or more sets of beams and one or more channel measurement resources (CMRs) to a user equipment (UE), such that the UE can identify CMRs from the one or more sets of beams based on the relationship information, measure the CMRs, and predict measurements for the predicted resource set based on the CMR measurements. In some examples, the UE can receive first control information indicating generation of a channel state information (CSI) report, where the CSI report is for measurement results related to a first set of beams. The UE can receive second control information indicating one or more CMRs and relationship information between one or more second sets of beams and the CMRs. In such examples, the one or more second sets of beams can be the same as the first set of beams, different from the first set of beams, or a combination thereof. The UE can measure the CMRs to obtain a set of measurement results, where the CMRs are identified based on the relationship information. Based on the CMR measurements, the UE can determine a set of prediction results, where each prediction result in the set of prediction results is associated with a beam in the first set of beams. The UE may send a CSI report with a reporting result including at least a subset of the prediction result set.

[0065] In some wireless communication systems, it may be beneficial for a user equipment (UE) to predict measurements of a beam set (e.g., a virtual resource or a predicted resource set) based on measurements of channel measurement resources (CMRs). For example, the UE may receive CMRs from a network entity, perform measurements on the CMRs, and extrapolate the CMR measurements to predict measurements of the beam set. That is, the UE may use CMR measurements to predict channel measurements associated with the beam set without having to receive and measure the beam set. To generate accurate predictions, the UE may use beam information associated with the CMRs and beam information associated with the beam set (such as beam shape information, spatial information, quasi-co-location (QCL) information, etc.) to perform predictions. However, in some cases, using current technology, the network entity may not be able to signal such information to the UE, resulting in inaccurate prediction results. For example, the network entity may not signal spatial information, beam information, or QCL information associated with both the beam set and the CMRs, resulting in inefficient communication.

[0066] The techniques, methods, and devices described herein may include a mechanism for signaling a relationship between a first set of beams (e.g., a predicted resource set or a candidate beam shape set) and CMRs, thereby enabling a UE to accurately predict measurements for the first set of beams based on CMR measurement results. For example, the UE may receive a channel state information (CSI) reporting setting associated with the first set of beams. The UE may also receive control information (e.g., such as downlink control information (DCI), radio resource control (RRC) signaling, or medium access control (MAC) signaling) indicating a relationship between the CMRs to be measured and one or more second sets of beams.

[0067] In some examples, the one or more second sets of beams may be the same as the first set of beams (e.g., the one or more second sets of beams are the first set of beams). In such examples, the relationship between the CMR and the one or more second sets of beams may indicate that the CMR is a subset of the one or more second sets of beams in terms of beam width, beam gain, beam pointing direction, etc. That is, the relationship information may indicate that the beam width, beam gain, or beam pointing direction of the CMR is similar to or the same as the beam width, beam gain, or beam pointing direction of the subset of the first set of beams (e.g., the predicted resource set). Therefore, the network entity may further indicate a bitmap, a combination index, or a resource identifier via the relationship information so that the UE can identify the CMR from the subset of the first set of beams.

[0068] In some other examples, the one or more second sets of beams may be a set of candidate beam shapes, where the candidate beam shape set may differ from the first set of beams in terms of beam gain, beam width, beam pointing direction, etc. In such examples, the relationship information may indicate that the beam width, beam gain, or beam pointing direction of the CMR is different from the beam width, beam gain, or beam pointing direction of the first set of beams, but may indicate that the beam width, beam gain, or beam pointing direction of the CMR is similar to or the same as a subset of the candidate beam shape set. Therefore, the network entity may further indicate a bitmap, a combination index, or a resource identifier via the relationship information so that the UE can identify the CMR from the subset of the candidate beam shape set.

[0069] In some other examples, the first set of the one or more second sets of beams may be the same as the first set of beams, and the second set of the one or more second sets of beams may be the same as the set of candidate beam shapes. Thus, the relationship information may indicate a first relationship between the CMR and the first set of beams and a second relationship between the CMR and the set of candidate beam shapes. Using such relationship information, the UE may monitor and receive the CMR, perform channel measurements on the CMR, and predict measurements of the first set of beams. In this way, the UE may receive an indication of the relationship between the CMR and the first set of beams, thereby enabling the UE to accurately perform predicted measurements without incurring additional overhead in the wireless communication system.

[0070] Aspects of the present disclosure are first described in the context of a wireless communication system. Figures 3A to 5 Aspects of the present disclosure are further described in the context of resource maps and resource indication maps as described herein. Figure 6 Aspects of the present disclosure are further described in the context of the described process flows.Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to techniques for efficient signaling for beam prediction.

In some examples, 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.

[0072] 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 examples, 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).

[0073] 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 both 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.

For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from the second node.

[0075] In some examples, network entities 105 can communicate with core network 130, with each other, or both. For example, network entities 105 can communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 can communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, 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 links 120, midhaul communication links 162, or fronthaul communication links 168 can 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 examples, the network entity 105 (e.g., a base station 140) may be implemented in a converged (e.g., monolithic, stand-alone) 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 examples, 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 a protocol stack that is 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 may also be referred to as a radio head, smart radio head, remote radio head (RRH), remote radio unit (RRU), or transmit receive point (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 examples, 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 CU 160, DU 165, and RU 170 is flexible and can support different functions depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack can be employed between CU 160 and DU 165 such that CU 160 can support one or more layers of a protocol stack and DU 165 can support one or more different layers of the protocol stack. In some examples, 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 examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 communicating via these communication links.

[0079] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to the 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., a 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 links 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., 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 examples, 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] Where the techniques described herein are applied to the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support the techniques described herein for efficient signaling for beam prediction. 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] 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 "device" may also be referred to as a unit, a station, a terminal, or a client, etc. 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 examples, 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 communication 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 ) 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., in the range of 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 examples, 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 may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a Transmit Time Interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0088] Physical channels may be multiplexed according to various techniques for communicating 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 examples, 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 examples, different coverage areas 110 associated with different technologies can overlap, but the different coverage areas 110 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 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functionality may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

[0091] In some examples, 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 examples, one or more UEs 115 in a group 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 aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group can be outside of the coverage area 110 of the network entity 105 or can otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, 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 of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving 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 transferred 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 can utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ license-assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology. 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 examples, operations using unlicensed bands can be based on a carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0095] 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 examples, the antennas or antenna arrays associated with the network entity 105 may be located at different geographic 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.

[0096] 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).

[0097] 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.

[0098] 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 (e.g., receiving network entity 105 or receiving UE 115)). In some examples, 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 by network entity 105 along different directions 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.

[0099] In some examples, transmission by a device (e.g., by network entity 105 or 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 network entity 105 to UE 115). 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. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), CSI reference signals (CSI-RS)), which may be precoded or not precoded. 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 selection 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).

[0100] A receiving device (e.g., UE 115) may 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 may 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 receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array (e.g., different directional listening weight sets), or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). 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).

[0101] UE 115 and network entity 105 may communicate data via various beams. For example, UE 115 may operate in an inactive or idle mode (e.g., RRC inactive or idle mode). When UE 115 operates in such a mode, network entity 105 may send one or more tracking reference signals (TRS) to UE 115. UE 115 may use such TRS to perform measurements and track one or more beams of network entity 105. When UE 115 has data to send, UE 115 may perform an initial access procedure to gain access to network entity 105. For example, UE 115 may perform a contention-based random access (CBRA) procedure, in which UE 115 may select a random access preamble to use in order to gain access to the network. In addition, UE 115 may receive one or more synchronization signal blocks (SSBs), perform a beam scanning procedure, and determine a beam to use for communicating with network entity 105.

[0102] In response to performing the CBRA procedure, UE 115 may gain access to the network and perform beam management to maintain a connected state (e.g., RRC_CONNECTED state). For example, UE 115 may perform a sunny day beam management procedure for both uplink beam management and downlink beam management. In downlink beam management (e.g., P1 / P2 / P3 downlink beam management procedure), UE 115 may receive one or more reference signals (e.g., SSB or CSI reference signal (CSI-RS)) to perform channel measurement and report it to network entity 105. In this way, UE 115 and network entity 105 may perform beam management in the downlink.

[0103] For uplink beam management (e.g., U1 / U2 / U3 uplink beam management procedures), UE 115 may transmit one or more sounding reference signals (SRSs) so that network entity 105 may perform channel measurements on such SRSs. In this way, UE 115 and network entity 105 may perform beam management in the uplink. In addition, UE 115 may report L1 reference signal received power (RSRP) (L1-RSRP), and network entity 105 may transmit a transmit configuration indicator (TCI) state configuration.

[0104] In some examples, UE 115 can report L1 signal-to-noise ratio (L1-SINR) of one or more reference signals when operating in connected mode. In some examples, UE 115 or network entity 105 can use one or more procedures to reduce latency and overhead. For example, component carrier group beam updates, relatively fast uplink beam updates, unified TCI states, L1 and L2-centric mobility, dynamic TCI updates, uplink multi-panel selection, maximum power extrapolation reduction, beam management delay reduction, etc. can be implemented to reduce latency in beam management. In some cases, UE 115 and network entities can perform beam management for multiple transmit and receive points (mTRPs) in the wireless system.

[0105] When operating in connected mode, the UE 115 or the network entity 105 may experience a beam failure. For example, based on measurements of SSB or CSI-RS in the downlink or SRS in the uplink, the UE 115 may perform a beam failure recovery procedure to reconnect to the network. For example, the UE 115 may implement beam failure detection and beam failure recovery procedures (e.g., for the primary cell and secondary cell of the network entity) to reduce the latency associated with the beam failure. For example, the UE may detect the beam failure based on measurements of a beam failure detection reference signal and downlink control channel block error rate monitoring. Based on detecting the beam failure, the UE 115 may use a contention-free random access (CFRA) beam recovery procedure, send a link recovery request, or perform a MAC-control element (MAC-CE) beam failure recovery procedure. In some examples, the UE 115 may be unable to perform beam failure recovery, which may result in a radio link failure.

[0106] In some examples of wireless communication system 100, network entity 105, UE 115, or both may employ artificial intelligence, machine learning, or both for air interface communication to improve performance, reduce complexity, and provide enhancements to NR systems, targeting one or more use cases. An initial set of use cases may include beam management, such as beam prediction in the time or spatial domain for overhead and latency reduction, beam selection accuracy improvement, or a combination thereof. Artificial intelligence and machine learning may be employed to ultimately identify representative sub-use cases for each use case for characterization and baseline performance evaluation. Such methods (e.g., artificial intelligence and machine learning) for the selected sub-use cases may be sufficiently diverse to support various requirements for the level of coordination between network entity 105 and UE 115 (e.g., gNB to UE). Furthermore, artificial intelligence and machine learning models and descriptions may identify common and specific features for framework investigation, such as characterizing the lifecycle management of artificial intelligence or machine learning models. That is, by employing artificial intelligence or machine learning in such use cases, model training, model deployment, model inference, model monitoring, model updates, or a combination thereof, may be investigated and implemented in such communication systems.

[0107] For example, beam management techniques based on artificial intelligence and machine learning can be supported in various scenarios. In a first beam management scenario (e.g., beam management scenario 1), machine learning and artificial intelligence can be used on the network or UE 115 side to perform spatial domain downlink beam prediction for a first set of beams (e.g., beam set A or a predicted resource set) based on measurement results of a second set of beams (e.g., set B beams or CMR). In a second beam management scenario (e.g., beam management scenario 2), artificial intelligence or machine learning can be used for temporal downlink beam prediction for the first set of beams based on historical measurement results of the second set of beams. For either scenario (e.g., the first beam management scenario or the second beam management scenario), the first set of beams and the second set of beams can be in the same frequency range (e.g., such as FR1, FR2, etc.).

[0108] Furthermore, artificial intelligence or machine learning may be used in a sub-use case of the first beam management scenario, where, in one example, the second set of beams is a subset of the first set of beams. In such a case, in order for the UE 115 or network entity 105 to perform such beam prediction, the UE 115 or network entity 105 may need to have an indication of the number of beams in both the first set of beams and the second set of beams, as well as an indication of how to identify the second set of beams from the first set of beams (e.g., via a fixed pattern, a random pattern, etc.). In another sub-use case of the first beam management scenario, artificial intelligence or machine learning may be used in cases where the first set of beams and the second set of beams are different (e.g., the first set of beams includes narrow beams and the second set of beams includes wide beams). In such a sub-use case, in order for the UE 115 or network entity 105 to accurately perform such beam management, the UE 115 or network entity 105 may need to have an indication of the number of beams in both the first set of beams and the second set of beams, as well as an indication of the QCL relationship between the first set of beams and the second set of beams. In such cases, the first set of beams may be used for downlink beam prediction and the second set of beams may be used for beam measurement. In addition, in either beam management case, codebook constructions for the first set of beams and the second set of beams may be identified.

[0109] In some cases, for the first beam management scenario, the UE 115 may operate an artificial intelligence or machine learning model (e.g., a UE-side model). In such a scenario, the UE 115 may send L1 signaling to report information inferred by the AI / ML model to the network entity 105. For example, the UE 115 may report one or more beams based on the output of the artificial intelligence or machine learning model inference, a predicted L1-RSRP corresponding to each of the one or more beams, and other information. Similarly, for beam management scenario 2, the UE 115 may operate an artificial intelligence or machine learning model. In such a scenario, the UE may send L1 signaling to report information associated with the artificial intelligence and machine learning model inference to the network entity 105. Such information may include one or more beams for N future time instances, where each beam and time instance is based on the output of the model inference. The UE 115 may also report the value of N, the predicted L1-RSRP corresponding to each of the one or more beams, a timestamp corresponding to each of the one or more reported beams (e.g., such information may be explicitly indicated or implicitly determined), and other information via L1 signaling.

[0110] For any beam management scenario where the UE 115 operates an artificial intelligence or machine learning model, the UE 115, the network entity 105, or both may perform model monitoring with potential down-selection. In one example, the UE 115 may perform model monitoring to monitor performance metrics and make determinations associated with model selection, activation, deactivation, switching, fallback operations, and the like. In some other scenarios, the network entity 105 may perform model monitoring to monitor performance metrics and make determinations regarding model selection, activation, deactivation, switching, fallback operations, and the like. Additionally or alternatively, both the network entity 105 and the UE 115 may monitor models (e.g., hybrid model monitoring), wherein the UE 115 may monitor performance metrics and the network entity 105 may make determinations regarding model selection, activation, deactivation, switching, fallback operations, and the like.

[0111] Alternatively, for either beam management scenario, the network entity 105 (e.g., or some network functional unit) may operate an artificial intelligence or machine learning model, wherein the network entity 105 may perform model monitoring. For example, the network entity 105 may monitor performance metrics and perform determinations regarding model selection, activation, deactivation, switching, fallback operations, and the like. Furthermore, in the case where the network entity 105 operates the model and performs model monitoring, the network entity 105 may control beam measurements and reporting for model monitoring. For example, if the network entity 105 using either beam management scenario is operating the model, the UE 115 may report measurement results for more than four beams in one reporting instance, wherein the network entity 105 may use such information (e.g., via the model) to perform beam prediction.

[0112] For sub-use cases in both the first beam management case and the second beam management case (e.g., spatial or temporal prediction for a first set of beams based on measurements of a second set of beams), the UE 115 and the network entity 105 may support at least model training and inference when the second set of beams is a subset of the first set of beams or when the first set of beams and the second set of beams are different. For example, if the second set of beams is a subset of the first set of beams, the network entity 105 may perform model training and inference. Alternatively, if the first set of beams and the second set of beams are different, the UE 115 may perform model training and inference. In some examples, the UE 115 and the network entity 105 may support model transfer between the UE 115 and the network entity 105. For example, the network entity 105 may perform model training while the UE 115 may perform model inference. In the case where the network entity 105 operates the model in either the first beam management case or the second beam management case, the UE 115 may report measurement results for more than four beams in one reporting instance via L1 signaling.

[0113] Regarding data collection for artificial intelligence or machine learning model training on the UE 115 side, the UE 115 or the network entity 105 may determine whether and how to initiate data collection, determine configurations related to the first set of beams and the second set of beams, and determine and share information associated with mapping the first set of beams and the second set of beams. In the example of data collection, the network entity 105 may send assistance information to the UE 115. In the case where the network entity 105 operates and monitors the model in any beam management scenario, the UE may report beam measurements based on the beam set indicated by the network entity 105. Such reporting may be through RRC messaging, L1 signaling, etc. In such cases, the performance, complexity, and power consumption of the UE 115 may be considered.

[0114] In some examples of the wireless communication system 100, it may be beneficial for the UE 115 to predict measurements of a beam set (e.g., a virtual resource or a predicted resource set) based on measurements of CMR. For example, the UE 115 may receive CMR from the network entity 105, perform measurements on the CMR, and extrapolate the CMR measurements to predict measurements of the beam set. That is, the UE 115 may use the CMR measurements to predict channel measurements associated with the beam set without having to receive and measure the beam set. To facilitate such operations, the UE 115 may use beam information associated with the CMR and beam information associated with the beam set (such as beam shape information, spatial information, QCL information, etc.) to perform predictions so that the UE 115 can accurately predict measurement results. However, in some cases, using current technology, the network entity 105 may not signal such information to the UE 115, resulting in inaccurate prediction results. For example, the network entity 105 may not signal spatial information, beam information, or QCL information associated with both the beam set and the CMR, resulting in inefficient communication.

[0115] The techniques, methods, and devices described herein may include a mechanism for signaling a relationship between a first set of beams (e.g., a predicted resource set) and CMRs, thereby enabling UE 115 to accurately predict measurements for the first set of beams based on CMR measurement results. For example, UE 115 may receive a CSI reporting setting associated with the first set of beams. UE 115 may also receive control information (e.g., such as DCI, RRC, or MAC signaling) indicating a relationship between the CMRs to be measured and one or more second sets of beams.

[0116] In some examples, the one or more second sets of beams may be the same as the first set of beams. In such examples, the relationship between the CMR and the one or more second sets of beams may indicate that the CMR is a subset of the one or more second sets of beams in terms of beam width, beam gain, beam pointing direction, etc. That is, the relationship information may indicate that the beam width, beam gain, or beam pointing direction of the CMR is similar to or the same as the beam width, beam gain, or beam pointing direction of the subset of the first set of beams (e.g., the predicted resource set). Therefore, the network entity 105 may further indicate a bitmap, a combination index, or a resource identifier via the relationship information so that the UE 115 can identify the CMR from the subset of the first set of resources.

[0117] In some other examples, the one or more second sets of beams may be a set of candidate beam shapes, where the candidate beam shape set may differ from the first set of beams in terms of beam gain, beam width, beam pointing direction, etc. In such examples, the relationship information may indicate that the beam width, beam gain, or beam pointing direction of the CMR is different from the beam width, beam gain, or beam pointing direction of the first set of beams, but may indicate that the beam width, beam gain, or beam pointing direction of the CMR is similar to or the same as the beam width, beam gain, or beam pointing direction of the candidate beam shape set. Therefore, the network entity 105 may further indicate a bitmap, a combination index, or a resource identifier via the relationship information so that the UE 115 can identify the CMR from a subset of the candidate beam shape set.

[0118] In some other examples, the first set of the one or more second sets of beams may be the same as the first set of beams, and the second set of the one or more second sets of beams may be a set of candidate beam shapes. Thus, the relationship information may indicate a first relationship between the CMR and the first set of beams and a second relationship between the CMR and the set of candidate beam shapes.

[0119] UE 115 may monitor CMR, receive CMR, and perform channel measurements on CMR. Using such relationship information indicated via control information, UE 115 may predict measurements of the first set of beams based on the CMR measurements. In this manner, UE 115 may receive an indication of the relationship between CMR and the first set of beams, thereby enabling UE 115 to perform predictive measurements.

[0120] Figure 2An example of a wireless communication system 200 that supports techniques for efficient signaling for beam prediction according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may implement aspects of the wireless communication system 100 or be implemented by these aspects. For example, the wireless communication system 200 may include a network entity 105-a and a UE 115-a, which may be a network entity 105-a and a UE 115-a. Figure 1 Examples of corresponding devices described.

[0121] In some cases, UE 115-a may use an artificial intelligence or machine learning model to predict measurements of predicted resource set 205 (e.g., a first set of beams, virtual resources, set A beams) based on measurements of CMR 210 (e.g., set B beams). That is, UE 115-a may perform spatial domain downlink beam prediction for predicted resource set 205 based on the measurement results of CMR 210, or perform temporal downlink beam prediction for predicted resource set 205 based on historical measurement results of CMR 210. In such cases, network entity 105-a may send CMR 210 to UE 115-a so that UE 115-a may perform channel measurement on CMR 210 and extrapolate the measurement results to predicted resource set 205 (e.g., which may or may not be sent from network entity 105-a).

[0122] To facilitate such beam prediction, UE 115-a may need to have an indication of the number of beams in predicted resource set 205 and CMR 210, an indication of the QCL relationship between predicted resource set 205 and CMR 210, an indication of how CMR 210 is determined from predicted resource set 205, etc. For example, in the case where CMR 210 is a subset of predicted resource set 205 (e.g., in terms of beam width, beam gain, etc.), UE 115-a may need to have an indication of the connection between predicted resource set 205 and CMR 210 in terms of beam shape or QCL information to perform accurate beam prediction. However, using current technology, network entity 105-a may not have sufficient signaling mechanisms regarding how to indicate such a connection (e.g., beam shape, QCL information, etc.) between CMR 210 and predicted resource set 205. That is, where the CMR 210 is a subset of the predicted resource set 205, the network entity 105-a may not have any mechanism for signaling such a relationship (eg, such as a bitmap combination index, an explicit index for identifying the CMR 210, etc.).

[0123] Furthermore, given that there may be multiple different combinations between the predicted resource set 205 and the CMR 210 (e.g., in the case of dynamic indication from the network entity 105-a via MAC-CE or DCI signaling), such signaling (e.g., if used by the network entity 105-a) should be efficient in terms of downlink overhead. Furthermore, the network entity 105-a may not have any signaling mechanism for indicating such a connection between the predicted resource set 205 and the CMR 210 (e.g., such as CSI report settings, MAC-CE activating the predicted resource set 205 or CMR 210, or aperiodic CSI triggering configuration). Furthermore, the network entity 105-a may not have a mechanism for signaling (e.g., such as a serving cell beam shape codebook or a CSI report setting specific beam shape codebook) the absolute or relative beam shapes that can be applied to the candidate resources of the predicted resource set 205 and the CMR 210. Therefore, if UE 115 - a does not have such information, UE 115 - a may not be able to accurately identify CMR 210 from predicted resource set 205 , resulting in inaccurate predicted measurements.

[0124] The techniques described herein may provide a signaling design to enable the network entity 105-a to indicate relationship information between the predicted resource set 205 and the CMR 210. Such techniques may be applied to scenarios where the CMR 210 is a subset of the predicted resource set 205, which may be referred to herein. Figure 3A and Figure 3B Further described. In addition, such techniques can be applied to the case where the CMR 210 may be different from the predicted resource set 205, but can be identified from the set of candidate beam shapes, which can be referenced herein. Figure 4A and Figure 4B In some examples, these techniques can be applied to situations where the first portion of the CMR 210 is a subset of the predicted resource set 205 and the second portion of the CMR 210 is a subset of the set of candidate beam shapes, which may be referenced herein. Figure 5 Further description.

[0125] That is, the techniques described herein may enable efficient signaling of CMR 210 for spatial domain beam prediction of a predicted resource set 205. In some examples, the network entity 105-a may request, via first control information 215, the UE 115-a to predict L1-RSRP, L1-SINR, or predict measurements for a certain number of resources (e.g., first K resources) in the predicted resource set 205 (e.g., which may be virtual resources), where the predicted resource set 205 is indicated via the first control information 215 (e.g., which may be an example of a CSI report setting). Furthermore, the network entity 105-a may request, via the first control information 215, the UE 115-a to report such predicted measurements of the predicted resource set 205, such as reporting L1-RSRP, L1-SINR, or predicted measurements for the number of resources (e.g., first K resources), via a CSI report 220.

[0126] For example, the network entity 105-a may transmit first control information 215 (e.g., CSI report settings) instructing the UE 115-a to generate a CSI report 220, such that the UE 115-a may report one or more results (e.g., predicted measurement results) related to the predicted resource set 205 via the CSI report 220. Furthermore, the first control information 215 may be associated with the number of CMRs 210. Accordingly, the network entity 105-a may transmit second control information 225 (e.g., such as RRC signaling, MAC-CE signaling, or DCI signaling) indicating time and frequency resources for the CMRs 210 and indicating relationship information indicating a relationship between the CMRs 210 and the predicted resource set 205, a relationship between the CMRs 210 and a set of candidate beam shapes, or a combination thereof. That is, the second control information 225 may indicate one or more second sets of beams (e.g., the predicted resource set 205, the set of candidate beam shapes, or both) and a relationship between the CMRs 210 and the one or more second sets of beams.

[0127] In some examples, the relationship information may indicate that the CMR 210 may be a subset of the predicted resource set 205. Thus, as illustrated in the beam pattern 225-a, the network entity 105-a may indicate via the relationship information in the second control information 225 that the CMR 210 and one or more resources in the predicted resource set 205 are connected to each other in terms of absolute or relative beam pointing direction, beam width, beam gain, or a combination thereof. Figure 3A and Figure 3B Such signaling and relationship information associated with the CMR 210 and the predicted resource set 205 is further described.

[0128] In some other examples, the relationship information may indicate that the CMR 210 is different from the predicted resource set 205. Thus, as illustrated in the beam pattern 225-b, the network entity 105-a may indicate, via the relationship information in the second control information 225, that the CMR 210 is different from the resources in the predicted resource set 205 in terms of absolute or relative beam pointing direction, beam width, beam gain, etc. In such examples, the network entity 105-a may further indicate, via the relationship information in the second control information 225, that the CMR 210 is different from the resources in the predicted resource set 205 (e.g., Figure 2 (not shown) and is selected from a set of candidate beam shapes. Figure 4A and Figure 4B Such signaling and relationship information associated with the CMR 210 and the set of candidate beam shapes is further described.

[0129] In some other examples, the relationship information may indicate that a first portion of the CMR 210 is a subset of the predicted resource set 205, while a second portion of the CMR 210 is different from the predicted resource set 205, wherein the second portion of the CMR 210 may be a subset of the candidate beam shape set. Thus, as illustrated in the beam pattern 225-c, the network entity 105-a may indicate, via the second control information 225, first relationship information between the first portion of the CMR 210 and one or more resources in the predicted resource set 205, and second relationship information between the second portion of the CMR 210 and one or more resources in the candidate beam shape set. Figure 5 Such signaling and relationship information associated with the CMR 210, the predicted resource set 205, and the candidate beam shape set is further described.

[0130] In some examples of the present disclosure, the predicted resource set 205 may be based on one or more SSBs, CSI-RSs, or a combination thereof, where such resources may be transmitted relatively less frequently than the CMRs 210. In some other examples, the resources in the predicted resource set 205 may not be explicitly transmitted from the network entity 105-a to the UE 115-a. Thus, the resources in the predicted resource set 205 may be referred to as virtual resources, where such virtual resources include beamforming information. For example, if the predicted resource set 205 is a virtual resource, the network entity 105-a may transmit beam shape information 230 associated with the predicted resource set 205, where the beam shape information 230 may include an absolute or relative beam pointing direction, a beam width, a beam gain, or a combination thereof. Similarly, in the case where the candidate beam shape set is a virtual resource, the network entity 105-a may transmit beam shape information 230 associated with the candidate beam shape set.

[0131] For example, to perform accurate prediction for the predicted resource set 205, the UE 115-a may use beam shape information 230 associated with the predicted resource set 205, the set of candidate beam shapes, or both, where the beam shape information 230 may include absolute or relative beam pointing directions, beam widths, beam gains, etc. Thus, the UE 115-a may receive beam shape information 230 that identifies a beam shape associated with the predicted resource set 205, the set of candidate beam shapes, or both.

[0132] In some examples, the network entity 105-a may transmit the beam shape information 230 via a codebook framework. For example, the network entity 105-a may transmit a beam shape codebook associated with the serving cell via the beam shape information 230, where all possible beam shapes that may be applied to resources in the predicted resource set 205, resources in the candidate beam shape set, or a combination thereof may be preconfigured by the serving cell of the UE 115-a as a codebook.

[0133] Additionally or alternatively, the network entity 105-a may transmit beam shape information 230 associated with a CSI reporting configuration. Thus, the network entity 105-a may indicate, via the beam shape information 230, all possible beam shapes that may be applied to resources in the predicted resource set 205, to the candidate beam shape set, or a combination thereof. In such an example, the network entity 105-a may configure the beam shape information 230 as a codebook (e.g., and transmit the beam shape information) via RRC signaling associated with the first control information (e.g., the CSI reporting configuration). That is, the network entity 105-a may transmit the beam shape information 230 via the codebook in one or more RRC messages, each RRC message being associated with a CSI reporting configuration that configures the predicted resource set 205 and the candidate beam shape set. In such an example, the beam shape information 230 may include a beam shape codebook that indicates absolute beam shape candidates or relative beam shape associations (e.g., indicating only beam directions for different candidates relative to each other, but without detailed direction information).

[0134] In the event that the CMR 210 is a subset of the predicted resource set 205, the network entity 105-a may transmit beam shaping information 230 via control signaling (e.g., such as RRC signaling, MAC-CE signaling, DCI signaling), wherein such control signaling is associated with the configuration, activation, and triggering of the predicted resource set 205 and is associated with the first control information (e.g., CSI reporting settings). Such control signaling including the beam shaping information 230 may identify a codepoint or index in a serving cell codebook or a CSI reporting settings codebook, wherein the UE 115-a may apply such codepoint to the predicted resource set 205. That is, the UE 115-a may receive or be preconfigured with (e.g., as defined in a standard document) a beam shaping codebook associated with the serving cell or the CSI reporting settings. The UE 115-a may further receive one or more codepoints or indices associated with the beam shaping codebook in the same or different control signaling, the beam shaping codebook identifying associated beam shaping information for the predicted resource set 205.

[0135] In the event that CMR 210 is different from predicted resource set 205 but can be identified from the candidate beam shape set, UE 115-a may receive configuration, activation, or triggering of the candidate beam shape set via control signaling, where such control signaling may also include codepoints associated with a codebook. In such an example, beam shape information identified from a serving cell codebook or a CSI report configuration codebook may be the candidate beam shape set.

[0136] Based on the relationship information indicated in the second control information 225 and the beam shape information 230, the UE 115-a may identify, receive, and measure the CMR 210. Thus, the UE 115-a may predict the L1-RSRP, the L1-SINR, or the measurement results for a threshold number of resources (e.g., the first K resources) in the predicted resource set 205 based on the relationship information (e.g., relationship) between the CMR 210 and the resources in the predicted resource set 205, based on the relationship information (e.g., selection details) between the CMR 210 and the candidate beam shapes from the candidate beam shape set, or a combination thereof. In some examples, the UE 115-a may perform such beam prediction based on a machine learning or artificial intelligence model.

[0137] In response to determining the prediction results for the predicted resource set 205, the UE 115-a may send a CSI report 220 indicating at least a subset of the prediction results. In some examples, the UE 115-a may report the predicted L1-RSRP and L1-SINR for each resource in the predicted resource set 205 (e.g., each beam in the first set of beams). Accordingly, the UE 115-a may include resource identifiers for the resources in the predicted resource set 205 having corresponding predicted L1-RSRP and L1-SINR. That is, the UE 115-a may include a corresponding resource identifier for each predicted measurement result, where each of the corresponding resource identifiers is associated with a corresponding resource in the predicted resource set 205.

[0138] In some other examples, if UE 115-a reports a subset of prediction results from predicted resource set 205 (e.g., the top K resources), the subset of prediction results may include the strongest predicted L1-RSRP and L1-SINR relative to other prediction results in predicted resource set 205. For example, UE 115-a may predict L1-RSRP and L1-SINR for each resource in predicted resource set 205. Based on an indication of a threshold number of reporting results in the first control information, UE 115-a may report up to the threshold number of prediction results, where the threshold number includes the relatively strongest predicted L1-RSRP and L1-SINR. As an illustrative example, network entity 105-a may instruct UE 115-a to report the top three prediction results in predicted resource set 205. Thus, UE 115-a may predict measurements for each resource in predicted resource set 205 and select the three strongest predicted resources from predicted resource set 205. In such an example, UE 115-a may include resource identifiers associated with the three prediction results.

[0139] Figure 3A and Figure 3B Examples of resource maps 300 and resource indication maps 301, respectively, are illustrated to support efficient signaling techniques for beam prediction according to one or more aspects of the present disclosure. The resource maps 300 and resource indication maps 301 may be implemented as described herein with reference to Figures 1 to 2 Aspects of the described wireless communication systems 100 and 200 may be implemented by or as such. For example, the resource map 300 and the resource indication map 301 may be implemented by the UE 115, the network entity 105, or both.

[0140] In addition, resource map 300 may include predicted resource set 305 and CMR 310, which may be examples of predicted resource set 205 and CMR 210. Network entity 105 may indicate CMR 310 from predicted resource set 305 using one of the indication techniques (e.g., bitmap 315, resource identifier 320, and combination index 325) as shown in resource indication map 301. In the case where one or more CMRs 310 are subsets of predicted resource set 305 in terms of beam shape, resource map 300 and resource indication map 301 may be implemented by such a device (e.g., network entity 105 or UE 115).

[0141] For example, the network entity 105 may send first control information (e.g., CSI report settings) requesting the UE 115 to perform beam prediction for the predicted resource set 305 based on the measurement of the CMR 310. Therefore, in the example of the resource map 300, the CMR 310 may be a subset of the predicted resource set 305 in terms of beam shape. That is, the beam shape (such as beam pointing direction, beam width, beam gain, etc.) of the transmitted CMR 310 may be similar to or the same as the beam shape of the subset of the predicted resource set 305 indicated in the first control information.

[0142] According to various aspects described herein, the network entity 105 may transmit relationship information between the CMRs 310 and the predicted resource set 305. For example, the network entity 105 may transmit first control information (e.g., CSI reporting settings), which indicates absolute or relative beam pointing directions, beam widths, and beam gains of a first number of resources in the predicted resource set 305 (e.g., the network entity 105 indicates N resources in the predicted resource set 305 via the CSI reporting settings). After or concurrently with transmitting the first control information, the network entity 105 may transmit second control information (e.g., such as RRC signaling, MAC-CE signaling, or DCI signaling), which indicates a certain number of CMRs 310 (e.g., indicating M CMRs 310) and indicates the absolute or relative beam pointing directions, beam widths, beam gains, etc. of the CMRs 310.

[0143] To indicate the beam shape information of the number of CMRs 310, the network entity 105 may include relationship information between the predicted resource set 305 and the CMRs 310 in the second control signaling, wherein such relationship information indicates that a subset of resources (e.g., M resources) is selected from the number of resources (e.g., N resources) in the predicted resource set 305. In other words, each CMR 310 may be associated with a corresponding resource in the predicted resource set 305. To indicate such relationship information (e.g., indicating M resources from the N resources in the predicted resource set 305, where the M resources represent the CMRs 310), the network entity 105 may send one of the resource indication techniques shown in the resource indication diagram 301.

[0144] In one example, network entity 105 may transmit a bitmap 315 via the second control information and as part of the relationship information, the bitmap having a length equal to the number of resources in predicted resource set 305 (e.g., bitmap 315 having a length N or N number of bits). Thus, each bit in bitmap 315 may be associated with a resource in predicted resource set 305. To indicate a CMR 310 from predicted resource set 305, network entity 105 may indicate a one in a bit position associated with CMR 310. As an illustrative example, if predicted resource set 305 includes 24 resources (e.g., 0 to 23), network entity 105 may indicate that resources 0, 3, 16, and 18 are associated with CMR 310 in terms of beamforming information. Thus, via bitmap 315, network entity 105 may indicate a one in the most significant bit (MSB) of bitmap 315, where the MSB in bitmap 315 may be associated with resource 0 in predicted resource set 305. Additionally, network entity 105 may include a one in subsequent bits in bitmap 315 to indicate that the third resource, the sixteenth resource, and the eighteenth resource in predicted resource set 305 are related to CMR 310. It should be understood that such illustrative examples do not represent all means and manners by which network entity 105-a may indicate relationship information via bitmap 315.

[0145] In another example, the network entity 105 may send resource identifiers 320 of the predicted resource set 305 associated with the CMRs 310 via the second control information and as part of the relationship information. That is, the network entity 105 may use the resource identifiers 320 to explicitly indicate the number of CMRs 310 from the number of resources in the predicted resource set 305 (e.g., to indicate M resources from N resources). The network entity 105 may use a certain number of bits to indicate the resource identifier. For example, to determine the number of bits, the network entity may take the base-two logarithm of the number of resources in the predicted resource set 305. As an illustrative example, if the predicted resource set 305 includes 24 resources and the CMRs 310 are associated with resource 0, resource 3, resource 16, and resource 18, the network entity 105 may send resource identifiers 320 associated with resource 0, resource 3, resource 16, and resource 18 via the second control information and as part of the relationship information. Thus, each resource identifier may be represented by five bits (e.g., ).

[0146] In another example, the network entity 105 may communicate via the second control information and as part of the relationship information (eg, via Units digit) sent A combined index 325 may be used by the UE 115 to select a number of CMRs 310 (e.g., M resource identifiers) from the number of resources (e.g., N resources) in the predicted resource set 305. Here, the first selected resource, the second selected resource, and the third selected resource in the predicted resource set 305 may be mapped to the first resource, the second resource, and the third resource in the CMR 310.

[0147] As described herein, the network entity 105 can send such relationship information (e.g., bitmap 315, resource identifier 320, combination index 325) via RRC signaling, MAC-CE signaling, DCI signaling, or a combination thereof. In the example of RRC signaling, the relationship information can be indicated via a configuration in first control information (e.g., CSI report settings) or via a configuration in second control information (e.g., via a configuration for CMR 310), where the second control information is associated with the first control information (e.g., CSI report settings).

[0148] In the example of MAC-CE signaling, the relationship information may be indicated via MAC-CE signaling that activates semi-persistent CSI reporting regarding first control information (e.g., CSI report setting) or by MAC-CE signaling that activates second control information (e.g., semi-persistent CMR 310 associated with the CSI report setting). In addition, the relationship information may be indicated in a separate MAC-CE that includes an identifier of the first control information (e.g., CSI report setting identifier) ​​or an identifier of the second control information (e.g., CMR 310 identifier).

[0149] In an example of DCI signaling, the relationship information may be indicated via a CSI reporting parameter (e.g., CSI-AssociatedReportConfigInfo) in first control information (e.g., an aperiodic CSI reporting configuration), where such relationship information may be triggered by a DCI requesting an aperiodic CSI report associated with the first control information (e.g., an aperiodic CSI reporting configuration). In some other examples, the relationship information may be indicated via one or more dedicated fields in DCI that may be associated with the first control information (e.g., a CSI reporting configuration), where such first control information (e.g., a CSI reporting configuration) is indicated in the DCI. Such dedicated DCI fields may also include an identifier associated with the first control information (e.g., a CSI reporting configuration identifier) ​​or an identifier associated with the second control information (e.g., an identifier associated with CMR 310).

[0150] Figure 4A and Figure 4B An example of a resource map 400 and a resource indication map 401 that support techniques for efficient signaling for beam prediction according to one or more aspects of the present disclosure is illustrated. The resource map 400 and the resource indication map 401 may be implemented as described herein with reference to Figures 1 to 3B Aspects of the described wireless communication system 100, wireless communication system 200, resource map 300, and resource indication map 301 may be implemented by or as such. For example, resource map 400 and resource indication map 401 may be implemented by UE 115, network entity 105, or both.

[0151] Resource map 400 may include predicted resource set 405 and CMR 410, which may be examples of corresponding resources as described herein. In addition, resource map 400 may include candidate beam shape set 415, which may be examples of corresponding resources as described herein. Figure 2 The resource indication map 401 may include a bitmap 420, a resource identifier 425, and a combination index 430, which may be as described herein. Figure 3B Examples of the described correspondence indication techniques.

[0152] The network entity 105 may use one of the indication techniques (e.g., bitmap 420, resource identifier 425, or combination index 430) as shown in the resource indication map 401 to indicate the CMR 410 from the candidate beam shape set 415. Therefore, in the case where one or more CMRs 410 differ from the predicted resource set 405 in terms of beam shape, the resource map 400 and the resource indication map 401 may be implemented by such a device (e.g., the network entity 105 or the UE 115), but the beam shape of the one or more CMRs 410 may be associated with the candidate beam shape set 415.

[0153] For example, the network entity 105 may send first control information (e.g., CSI report settings) requesting the UE 115 to perform beam prediction for the predicted resource set 405 based on measurements of the CMR 410. Thus, in the example of the resource map 400, the CMR 410 differs from the predicted resource set 405 in terms of beam shape, but the beam shape of one or more CMRs 410 may be associated with the candidate beam shape set 415. That is, the beam shape (such as beam pointing direction, beam width, beam gain, etc.) of the transmitted CMR 410 may not be directly related to the beam shape of the predicted resource set 405 indicated in the first control information. However, the CMR 410 may be similar to or identical to a subset of the candidate beam shape set 415 and may be selected from the candidate beam shape set 415.

[0154] According to various aspects described herein, the network entity 105 may transmit information regarding a relationship between the CMR 410 and the candidate beam shape set 415. For example, the network entity 105 may transmit first control information (e.g., a CSI reporting setting) indicating absolute or relative beam pointing directions, beam widths, and beam gains for a first number of resources in the candidate beam shape set 415 (e.g., the network entity 105 indicates N′ resources in the candidate beam shape set 415 via the CSI reporting setting). In such an example, the first control information may also include an indication of the predicted resource set 405.

[0155] After sending the first control information or concurrently with sending the first control information, the network entity 105 may send second control information (e.g., such as RRC signaling, MAC-CE signaling, DCI signaling), where the second control information indicates a certain number of CMRs 410 (e.g., indicating M CMRs 410) and indicates the absolute or relative beam pointing direction, beam width, beam gain, etc. of the CMRs 410.

[0156] To indicate the beam shape information of the number of CMRs 410, the network entity 105 may include relationship information between the candidate beam shape set 415 and the CMRs 410 in the second control information, wherein such relationship information indicates that a subset of resources (e.g., M resources) is selected from the number of resources (e.g., N' resources) in the candidate beam shape set 415. In other words, the beam shape of each CMR 410 may be associated with a corresponding resource in the candidate beam shape set 415. To indicate such relationship information (e.g., indicating M resources from the N' resources in the candidate beam shape set 415, where the M resources represent the CMRs 410), the network entity 105 may send one of the resource indication techniques shown in the resource indication diagram 401.

[0157] In one example, the network entity 105 may transmit a bitmap 420 via the second control information and as part of the relationship information, the bitmap having a length equal to the number of resources in the candidate beam shape set 415 (e.g., a bitmap 420 of length N'). Thus, each bit in the bitmap 420 may be associated with a resource in the candidate beam shape set 415. To indicate a CMR 410 from the candidate beam shape set 415, the network entity 105 may indicate a one in a bit position associated with the CMR 410. As an illustrative example, if the candidate beam shape set 415 includes 24 resources (e.g., 0 to 23), the network entity 105 may indicate that resources 0, 3, 16, and 18 are associated with the CMR 410 in terms of beam shape information. Thus, via the bitmap 420, the network entity 105 may indicate a one in the MSB of the bitmap 420, where the MSB in the bitmap 420 may be associated with resource 0 in the candidate beam shape set 415. Additionally, the network entity 105 may include a one in subsequent bits in the bitmap 420 to indicate that the third resource, the sixteenth resource, and the eighteenth resource in the set of candidate beam shapes 415 are related to the CMR 410 in terms of beam shape.

[0158] In another example, the network entity 105 may transmit a resource identifier 425 (e.g., a shape identifier) ​​associated with the CMR 410 for the candidate beam shape set 415 via the second control information and as part of the relationship information. That is, the network entity 105 may use the resource identifier 425 to explicitly indicate the number of CMRs 410 from the number of resources in the candidate beam shape set 415 (e.g., indicating M resources from N' resources). The network entity 105 may use a certain number of bits to indicate the resource identifier. For example, to determine the number of bits, the network entity 105 may take the base-two logarithm of the number of resources in the candidate beam shape set 415. As an illustrative example, if the candidate beam shape set 415 includes 24 resources and the beam shapes of the CMR 410 are associated with the beam shapes of resources 0, 3, 16, and 18, the network entity 105 may transmit the resource identifiers 425 associated with resources 0, 3, 16, and 18 via the second control information and as part of the relationship information. Therefore, each resource identifier can be represented by five bits (e.g., ).

[0159] In another example, the network entity 105 may communicate via the second control information and as part of the relationship information (eg, via Units digit) sent A combination index 430 may be used by the UE 115 to select the number of CMRs 410 (e.g., M shape identifiers) from the number of resources (e.g., N′ shape resources) in the candidate beam shape set 415. Here, the first selected resource, the second selected resource, and the third selected resource in the candidate beam shape set 415 may be mapped to the first resource, the second resource, and the third resource in the CMR 410.

[0160] As described herein, the network entity 105 may send such relationship information (e.g., bitmap 420, resource identifier 425, or combination index 430) via RRC signaling, MAC-CE signaling, DCI signaling, or a combination thereof. In the example of RRC signaling, the relationship information may be indicated via a configuration in first control information (e.g., CSI report settings) or via a configuration in second control information (e.g., via a configuration for CMR 410), where the second control information is associated with the first control information (e.g., CSI report settings).

[0161] In the example of MAC-CE signaling, the relationship information may be indicated via MAC-CE signaling of activating semi-persistent CSI reporting regarding first control information (e.g., CSI report setting) or by activating MAC-CE signaling of second control information (e.g., semi-persistent CMR 410 associated with CSI report setting). In addition, the relationship information may be indicated in a separate MAC-CE including an identifier of the first control information (e.g., CSI report setting identifier) ​​or an identifier of the second control information (e.g., CMR 410 identifier).

[0162] In an example of DCI signaling, the relationship information may be indicated via a CSI reporting parameter (e.g., CSI-AssociatedReportConfigInfo) in first control information (e.g., an aperiodic CSI reporting configuration), where such relationship information may be triggered by a DCI requesting an aperiodic CSI report associated with the first control information (e.g., an aperiodic CSI reporting configuration). In some other examples, the relationship information may be indicated via one or more dedicated fields in DCI associated with the first control information (e.g., a CSI reporting configuration), where such first control information (e.g., a CSI reporting configuration) is indicated in the DCI. Such dedicated DCI fields may also include an identifier associated with the first control information (e.g., a CSI reporting configuration identifier) ​​or an identifier associated with the second control information (e.g., an identifier associated with CMR 410).

[0163] Figure 5 An example of a resource map 500 that supports techniques for efficient signaling for beam prediction according to one or more aspects of the present disclosure is illustrated. The resource map 500 may be implemented as described herein with reference to Figures 1 to 4B Aspects of the wireless communication system 100, wireless communication system 200, resource map 300, resource indication map 301, resource map 400, and resource indication map 401 described herein may be implemented by or as such. For example, resource map 500 may be implemented by UE 115, network entity 105, or both. Resource map 500 may include a predicted resource set 505, a CMR 510, and a candidate beam shape set 515, which may be examples of corresponding resources as described herein.

[0164] In some examples, network entity 105 may transmit first control information (e.g., CSI report settings) requesting UE 115 to perform beam prediction for predicted resource set 505 based on measurements of CMR 510. Thus, in the example of resource map 500, a first portion of CMR 510 may be a subset of predicted resource set 505 in terms of beam shape, while a second portion of CMR 510 may be a subset of candidate beam shape set 515 in terms of beam shape. That is, a first portion of the beam shape of the transmitted CMR 510 (such as beam pointing direction, beam width, beam gain, etc.) may be a subset of predicted resource set 505, while a second portion (e.g., the remaining portion) of the beam shape of the transmitted CMR 510 may not be directly associated with resources in predicted resource set 505. Thus, the beam shape of the second portion of CMR 510 may be the same as or similar to the beam shape of candidate beam shape set 515.

[0165] In such examples, UE 115 may refer to Figure 3A and Figure 3B The described technology is used to receive the relationship information (eg, the connection) between the first part of the CMR 510 and the predicted resource set 505, and according to the reference Figure 4A and Figure 4B The described techniques are used to receive separate signaling for relationship information between the second portion of the CMR 510 and the set of candidate beam shapes 515 .

[0166] In some examples, the first portion and the second portion of the CMRs 510 may be associated with a first set of CMRs 510 and a second set of CMRs 510, respectively, where both the first set of CMRs 510 and the second set of CMRs 510 may be indicated via second control information associated with first control information (e.g., CSI report settings) indicating both the predicted resource set 505 and the set of candidate beam shapes 515. For example, the network entity 105 may send first control information indicating generation of a CSI report including prediction results related to the predicted resource set 505. In the first control information, the network entity 105 may indicate resources (e.g., virtual or additional) in the predicted resource set 505, resources in the set of candidate beam shapes 515, or both.

[0167] Thus, the network entity 105 may indicate first relationship information (e.g., association) between the first portion of the CMR 510 (e.g., the first set of the CMR 510) and the predicted resource set 505 via RRC signaling indicating the first portion of the CMR 510 (e.g., indicating the first set of the CMR 510). In some other examples, the network entity 105 may indicate the first relationship (e.g., association) between the first portion of the CMR 510 (e.g., the first set of the CMR 510) and the predicted resource set 505 via MAC-CE signaling activating the first portion of the CMR 510. Additionally, the network entity 105 may separately transmit second relationship information between the beam shapes of the second portion of the CMR 510 (e.g., the second set of the CMR 510) and the candidate beam shape set 515 via RRC signaling indicating the second portion of the CMR 510. In some other examples, the network entity 105 may indicate second relationship information (e.g., connection) between the second portion of the CMR 510 (e.g., the second set of CMRs 510) and the set of candidate beam shapes 515 via MAC-CE signaling that activates the second semi-persistent portion of the CMR 510.

[0168] That is, after sending the first control information or concurrently with sending the first control information, the network entity 105 may send a first RRC or MAC-CE message indicating a first part of the CMR 510 (e.g., a first set of CMRs 510) and indicating a relationship between the first part of the CMR 510 and the predicted resource set 505, and may send a second RRC or MAC-CE message indicating a second part of the CMR 510 (e.g., a second set of CMRs 510) and indicating a relationship between the second part of the CMR 510 and the candidate beam shape set 515.

[0169] In such examples, the first relationship information and the second relationship information may also include corresponding bitmaps, resource identifiers, combination indexes, etc. Therefore, the UE 115 may refer to the reference numerals in this document. Figure 3A and Figure 3B The described techniques identify the first portion of the CMR 510 from the predicted resource set 505. In addition, the UE 115 may use the Figure 4A and Figure 4B The described techniques identify a second portion of the CMR 510 from the set of candidate beam shapes 515 .

[0170] In some other examples, the first portion of the CMRs 510 and the second portion of the CMRs 510 may be indicated via a single set of CMRs 510. Thus, the network entity 105 may send second control information (e.g., such as an RRC configuration) indicating the single set of CMRs 510, wherein such second control information may further indicate a separation between the first portion and the second portion of the single set of CMRs 510. For example, the network entity 105 may send a single control message indicating first relationship information (e.g., a first relationship) between the first portion of the CMRs 510 and the predicted resource set 505, and, in addition, indicating second relationship information (e.g., a second relationship) between the beam shape of the second portion of the CMRs 510 and the set of candidate beam shapes 515. In such an example, the network entity 105 may send an RRC message indicating the single set of CMRs 510 and the first relationship information and the second relationship information. Alternatively, the network entity 105 may transmit a MAC-CE signal that activates the semi-persistent CMR 510 and further indicates the first relationship information and the second relationship information.

[0171] In such examples, the first relationship information and the second relationship information may also include corresponding bitmaps, resource identifiers, combination indexes, etc. Therefore, the UE 115 may refer to the reference numerals in this document. Figure 3A and Figure 3B The described techniques identify the first portion of the CMR 510 from the predicted resource set 505. In addition, the UE 115 may use the Figure 4A and Figure 4B The described techniques identify a second portion of the CMR 510 from the set of candidate beam shapes 515 .

[0172] Figure 6 An example of a process flow 600 for supporting techniques for efficient signaling for beam prediction according to one or more aspects of the present disclosure is illustrated. The process flow 600 may be implemented as described herein with reference to Figures 1 to 5 Aspects of the wireless communication system 100, wireless communication system 200, resource map 300, resource indication map 301, resource map 400, resource indication map 401, and resource map 500 described herein may be implemented by or as such. For example, process flow 600 may include UE 115-b and network entity 105-b, which may be examples of corresponding devices described herein. In the following description of process flow 600, operations may be performed in an order different from that shown. Certain operations may also be excluded from process flow 600, or other operations may be added to process flow 600. Furthermore, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations may actually occur simultaneously.

[0173] At 605, UE 115-b may receive first control information from network entity 105-b indicating that UE 115-b is to generate a CSI report including reporting results related to a first set of beams. The first set of beams may be an example of a predicted resource set as described herein. In some examples, UE 115-b may receive an indication of a set of candidate beam shapes via the first control information. The first control information may be an example of a CSI report setting.

[0174] At 610, UE 115-b may receive second control information indicating one or more CMRs and relationship information indicating a relationship (e.g., association) between one or more second sets of beams and the one or more CMRs. The one or more second sets of beams may be the same as the first set of beams, may be a different set of candidate beam shapes than the first set of beams, or a combination thereof.

[0175] That is, the relationship information may indicate that one or more CMRs are a subset of the first set of beams (eg, the CMRs are a subset of the predicted resource set), as described herein with reference to Figure 3A and Figure 3B In some examples, the relationship information may indicate that one or more CMRs are different from the first set of beams, but may be a subset of the set of candidate beam shapes, as described herein with reference to Figure 4A and Figure 4B In some other examples, the second control information may include first relationship information associated with a first portion of CMRs that is a subset of the first set of beams, and may include second relationship information associated with a second portion of CMRs that is a subset of the set of candidate beam shapes, as described herein with reference to Figure 5 The relationship information may also include a bitmap, resource identifier, or combined index as described herein.

[0176] At 615, UE 115-b may receive beam shape information associated with the first set of beams, the set of candidate beam shapes, or both. In some examples, the beam shape information may include absolute or relative beam pointing directions, beam gains, beam widths, etc. The beam shape information may be associated with a first set of beams, a set of candidate beam shapes, or both. Figure 2 The one or more codebooks described are associated.

[0177] At 620, based on the relationship information and the beam shape information, the UE 115-b may identify the beam shape of the one or more CMRs. At 625, the UE 115-b may measure the one or more CMRs to obtain a set of measurement results. The set of measurement results may be the L1-RSRP or L1-SINR of the CMRs.

[0178] At 630, UE 115-b may determine a set of predictions based on the set of measurements, where each prediction in the set of predictions is associated with the first set of beams. That is, UE 115-b may use the CMR measurements to predict measurements of the first set of beams. Such predictions may be L1-RSRP and L1-SINR for the first set of beams.

[0179] At 635, UE 115-b may send a CSI report including a report result. In some examples, the report result includes each prediction result in the set of prediction results, wherein such report result includes a resource identifier associated with each prediction result. Alternatively, the report result may include a resource identifier as described herein. Figure 2 A subset of the described set of prediction results (e.g., the top K resources).

[0180] Figure 7 A block diagram 700 illustrates a device 705 that supports techniques for efficient signaling for beam prediction according to one or more aspects of the present disclosure. The device 705 can be an example of aspects of the UE 115 as described herein. The device 705 can include a receiver 710, a transmitter 715, and a communication manager 720. The device 705 can also include a processor. Each of these components can communicate with each other (e.g., via one or more buses).

[0181] The receiver 710 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for efficient signaling for beam prediction). The information may be delivered to other components of the device 705. The receiver 710 may utilize a single antenna or a collection of multiple antennas.

[0182] The transmitter 715 may provide means for transmitting signals generated by other components of the device 705. For example, the transmitter 715 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for efficient signaling for beam prediction). In some examples, the transmitter 715 may be co-located with the receiver 710 in a transceiver module. The transmitter 715 may utilize a single antenna or a collection of multiple antennas.

[0183] The communication manager 720, the receiver 710, the transmitter 715, or various combinations thereof, or various components thereof, may be examples of means for performing various aspects of the techniques for efficient signaling for beam prediction as described herein. For example, the communication manager 720, the receiver 710, the transmitter 715, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.

[0184] In some examples, the communication manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof can be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, a digital signal processor (DSP), a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof that is configured as or otherwise supports components for performing the functions described in this disclosure. In some examples, the processor and a memory coupled to the processor can be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in the memory by the processor).

[0185] Additionally or alternatively, in some examples, the communication manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be performed by a general-purpose processor (e.g., a DSP, a CPU, an ASIC, an FPGA, a microcontroller), or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting means for performing the functions described in this disclosure).
