Technical Field

[0003] The following discussion relates to wireless communications, including a report on mutual information (MI) used for multi-beam operation. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (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 technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication of communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting the reporting of mutual information (MI) for multi-beam operation. For example, the described techniques enable a user equipment (UE) to consider receive beam correlation when selecting a first receive beam and a second receive beam. For instance, a network entity may configure the UE using multiple Channel State Information Reference Signal (CSI-RS) resource configurations. The network entity may configure the UE to report MI metrics for one or more CSI-RS resource configurations. In some examples, the network entity may configure the UE using a reporting configuration for each CSI-RS resource configuration and may select a CSI-RS resource configuration (e.g., a pair of transmit beams) for the UE to report MI. In some examples, the network entity may configure the UE using a single reporting configuration, and the UE may select a CSI-RS resource configuration to report MI (e.g., the CSI-RS resource configuration with the highest MI). In some examples, a network entity may configure a UE using two CSI-RS resource configurations (e.g., each including multiple transmit beams), and the UE may report the MI metric for a single CSI-RS resource in each CSI-RS resource configuration (e.g., the transmit beam from each CSI-RS resource configuration). Additionally or alternatively, the UE may report the Reference Signal Received Power (RSRP) (e.g., determined by performing a weighted sum of RSRP using one or more broadband coefficients).

[0049] In some wireless communication systems, user equipment (UE) can perform beam management procedures to select one or more pairs of transmit and receive beams for use by the UE in communications with network entities. For example, the UE can report the Reference Signal Received Power (RSRP) or Signal-to-Noise Plus Interference Ratio (SNIR) associated with Channel State Information Reference Signals (CSI-RS) received via the transmit and receive beams. In some examples, the UE can use multiple cross-polarized antenna panels to achieve higher communication ranks (e.g., for single-user (SU) multiple-input multiple-output (MIMO) communication), and the rank achievable in SU-MIMO communication may depend on the correlation between the first and second receive beams selected by the UE (e.g., during the beam management procedure). However, some beam management procedures may not consider the correlation between the first and second receive beams, which could result in a relatively lower achievable rank compared to receive beams with lower correlation.

[0050] Accordingly, the techniques described herein allow a UE to consider receive beam correlation when selecting a first and a second receive beam. For example, a network entity can configure the UE using multiple CSI-RS resource configurations (e.g., configurations indicating that repetition is enabled so that the network entity can transmit multiple times via each transmit beam, one or more resources indicating which CSI-RS the network entity can transmit via, the number of CSI-RS the network entity can transmit via each beam, etc.). The network entity can configure the UE to report mutual information (MI) metrics (e.g., metrics considering beam quality, correlation, etc.) for one or more combinations of transmit and receive beam pairs. The MI metrics reported by the UE can consider both the quality of each of the transmit and receive beams and the correlation between the receive beam pairs. Therefore, beams selected via an MI-based beam management process can consider the correlation between receive beams, potentially achieving a relatively high achievable rank compared to some other beam management processes.

[0051] In some examples, a network entity may configure the UE using a reporting configuration for each CSI-RS resource configuration in the CSI-RS resource configuration, and may select a CSI-RS resource configuration (e.g., a pair of transmit beams) for the UE to report MI. In some examples, a network entity may configure the UE using a single reporting configuration, and the UE may select a CSI-RS resource configuration to report MI (e.g., the CSI-RS resource configuration with the highest MI). In some examples, a network entity may configure the UE using two CSI-RS resource configurations (e.g., each including multiple transmit beams), and the UE may report the MI metric for a single CSI-RS resource in each CSI-RS resource configuration (e.g., the transmit beams from each CSI-RS resource configuration). Additionally or alternatively, the UE may report RSRP (e.g., determined by performing a weighted sum of RSRP using one or more bandwidth coefficients).

[0052] The aspects of this disclosure are first described in the context of wireless communication systems. These aspects are further illustrated by signaling diagrams, process flowcharts, apparatus diagrams, system diagrams, and flowcharts relating to a MI used for multi-beam operation, and are further described with reference to these diagrams.

[0053] Figure 1 An example of a wireless communication system 100 for multi-beam operation of a MI, supported by one or more aspects of this disclosure, is shown. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some 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 under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0054] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0055] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.

[0056] As described herein, nodes of the wireless communication system 100 (which may be referred to as network nodes or wireless nodes) may be network entity 105 (e.g., any network entity described herein), UE 115 (e.g., any UE described herein), network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0057] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may 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 may 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 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0058] One or more network entities in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or gigabit NodeB (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home NodeB, home eNodeB or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (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 base station 140).

[0059] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across 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, network entity 105 may 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, a non-real-time RIC), a Service Management and Orchestration (SMO) 180 system, or any combination thereof. RU 170 may also be referred to as a radio headend, an intelligent radio headend, a remote radio headend (RRH), a remote radio unit (RRU), or a transmit-receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0060] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to 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)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by the corresponding network entities 105 communicating via such communication links.

[0061] In a wireless communication system (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, 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 IAB node 104) may be configured to operate according to the techniques described herein.

[0062] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support MI for multi-beam operations as described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0063] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0064] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, network entities 105, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0065] UE 115 and network entity 105 can 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" can refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating 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 coordinating carrier operation, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0066] In some examples, such as in carrier aggregation configurations, a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel grating used for discovery by UE 115. A carrier may operate in standalone mode, in which case initial acquisition and connection can be performed by UE 115 via that carrier, or the carrier may operate in non-standalone mode, in which case different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.

[0067] The communication link 125 shown in the wireless communication system 100 may include downlink transmission (e.g., forward link transmission) from network entity 105 to UE 115, uplink transmission (e.g., return link transmission) from UE 115 to network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0068] A carrier may be associated with a specific bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one bandwidth in a set of bandwidths for a particular radio access technology (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., network entity 105, UE 115, or both) may have hardware configurations that support communication using a specific carrier bandwidth, or may be configured to support communication using one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include network entity 105 or UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0069] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where 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 decoding 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 modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal 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.

[0070] It can support one or more sets of parameters for a carrier, and the set of parameters may include subcarrier spacing ( (and cyclic prefix). A carrier can be divided into one or more BWPs with the same or different sets of parameters. In some examples, UE 115 can be configured to utilize multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and communication for UE 115 can be constrained to one or more active BWPs.

[0071] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, in response This can represent the supported subcarrier spacing, while This can represent the supported Discrete Fourier Transform (DFT) size. The time interval for organizing communication resources can be based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0072] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may also be divided into a 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 number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0073] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0074] Depending on the technology, carriers can be used to multiplex physical channels for communication. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search for control regions to obtain control information based on 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 concatenated manner. The aggregation level of control channel candidates 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 set may include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0075] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0076] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, 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 functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0077] In some examples, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s performing D2D communication in a group may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UE 115s in such a group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, the group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system in which each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.

[0078] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can 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), 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), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0079] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0080] The wireless communication system 100 can also operate using the ultra-high frequency (SHF) region (also known as the centimeter band) in the range of 3 GHz to 30 GHz or the extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, such techniques facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmission, EHF transmission may experience even greater attenuation and a shorter range. The techniques disclosed herein can be adopted across transmissions using one or more different frequency zones, and the frequency band usage specified across these frequency zones may vary by country or regulatory authority.

[0081] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0082] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, MIMO communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation 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 network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0083] Network entity 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. The multiple signals can be transmitted, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include: single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0084] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device by the transmitting or receiving device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0085] Network entity 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, 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 UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by network entity 105 along different directions. For example, network entity 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105) or by a receiving device (such as UE 115)) the beam direction for later transmission or reception by network entity 105.

[0086] Some signals (such as data signals associated with a specific 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., the direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted along one or more beam directions. For example, UE 115 may receive one or more signals transmitted by network entity 105 in different directions and may report to network entity 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0087] In some examples, transmissions performed by a device (e.g., network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital pre-decoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating pre-decoding weights for one or more beam directions, and this 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), channel state information reference signals (CSI-RS)) that may or may not be pre-decoded. UE 115 may provide feedback for beam selection, which may be a pre-decoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described with reference to signals transmitted by network entity 105 (e.g., base station 140, RU 170) in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception), or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0088] 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 transmitting 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 the received signals according to different antenna subarrays; receiving according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing the received signals according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these operations 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 a data signal is received). A single receiver configuration can be aligned along a beam direction determined based on listening according to different receiver 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).

[0089] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer can be IP-based. The RLC layer performs packet segmentation and reassembly for transmission via logical channels. The MAC layer performs priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection, error correction, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer provides the establishment, configuration, and maintenance of RRC connections between the UE 115 and network entity 105 or core network 130 that support user plane data radio bearers. The PHY layer maps transport channels to physical channels.

[0090] UE 115 and network entity 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data via communication links (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device can provide HARQ feedback in a specific time slot for data received via a previous symbol in that time slot. In some other examples, the device may provide HARQ feedback in subsequent time slots or according to a different time interval.

[0091] According to the techniques described herein, UE 115 can consider receive beam correlation when selecting a first receive beam and a second receive beam. For example, network entity 105 can configure UE 115 using multiple CSI-RS resource configurations (e.g., where repetition is enabled, causing the network entity to transmit multiple times via each transmit beam). Network entity 105 can configure UE 115 to report MI metrics (e.g., metrics that consider beam quality and correlation) for one or more CSI-RS resource configurations in the CSI-RS resource configurations.

[0092] In some examples, network entity 105 may configure UE 115 using a reporting configuration for each CSI-RS resource configuration in the CSI-RS resource configuration, and may select a CSI-RS resource configuration (e.g., a pair of transmit beams) for UE 115 to report MI. In some examples, network entity 105 may configure UE 115 using a single reporting configuration, and UE 115 may select a CSI-RS resource configuration to report MI (e.g., the CSI-RS resource configuration with the highest MI). In some examples, network entity 105 may configure UE 115 using two CSI-RS resource configurations (e.g., each including multiple transmit beams). UE 115 may report the MI metric for a single CSI-RS resource in each CSI-RS resource configuration (e.g., transmit beams from each CSI-RS resource configuration). Additionally or alternatively, UE 115 may report RSRP associated with one or more beams (e.g., determined by performing a weighted sum of RSRPs using one or more broadband coefficients).

[0093] Figure 2An example of a wireless communication system 200 for multi-beam operation of a MI is shown, supporting one or more aspects of this disclosure. The wireless communication system 200 may implement, or be implemented by, aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a UE 115 (e.g., UE 115-a) and a network entity 105 (e.g., network entity 105-a), which may be as described in reference... Figure 1 Examples of the corresponding devices described.

[0094] In some examples of the wireless communication system 200, UE 115-a can communicate with network entity 105-a via one or more beams. For example, network entity 105-a can send one or more messages to UE 115-a via one or more transmit beams 205 (e.g., transmit beams 205-a to transmit beams 205-f), and UE 115-a can receive the one or more messages via one or more receive beams (e.g., receive beams 210-a, 210-b, and 210-c). In some examples, to support higher rank (e.g., greater than rank 2) SU-MIMO operation, UE 115-a and network entity 105-a can have more than one cross-polarized (e.g., x-pol) antenna panel. That is, each cross-polarized panel can support up to rank 2 MIMO communication (e.g., via two ports), and therefore UE 115-a and network entity 105-a can use multiple cross-polarized panels to support rank 3 or higher communication. Additionally, some frequency bands (e.g., FR2) can rely on analog beamforming to combat path loss, and thus multiple cross-polarized antenna panels can be used in such bands.

[0095] In some examples, UE 115-a may select a receive beam 210 for each cross-polarized antenna panel in the cross-polarized antenna panel to support MIMO communication greater than rank 2 (e.g., two receive beams). For example, if UE 115-a uses the same receive beam 210 at each cross-polarized panel (e.g., or a similar or related receive beam 210), the beamforming channel between UE 115-a and network entity 105-a may have a low-rank condition (e.g., rank 2 or lower).

[0096] To select receive beam 210 (e.g., and transmit beam 205), UE 115-a may perform a beam management procedure followed by a CSI acquisition procedure. For example, UE 115-a may use beam management to address receive SNR (e.g., prioritizing the CSI framework). However, the beam management procedure may restrict the MIMO channel to a subspace (e.g., the dominant subspace) within the available dimensions. That is, the beam management procedure may reduce the number of beams that UE 115-a can select. Therefore, UE 115-a and network entity 105-a may individually select each transmit beam 205 and receive beam 210 in the transmit and receive beam pairs (e.g., based on RSRP or signal-to-noise plus-interference ratio (SINR)) and may not consider achievable rank in beam selection. In other words, CSI acquisition following beam management may not support high-rank (e.g., greater than rank 2) SU-MIMO.

[0097] To perform the beam management procedure and then the CSI acquisition procedure, network entity 105-a may configure UE 115-a to feed back multiple CSI Resource Indicators (CRIs) or Synchronization Signal Block Resource Indicators (SSBRIs) and send an associated L1 reporting quantity (e.g., in a single report) for each CRI or SSBRI. Each CRI or SSBRI may refer to a reference signal resource transmitted by network entity 105-a using a different transmit beam. Each CSI or SSBRI may also be associated with a Quasi-Co-located (QCL) receive beam 210 reference (e.g., with QCL type D). The associated L1 reporting quantity for each CRI or SSBRI may include an RSRP or SNIR associated with each CRI or SSBRI (e.g., associated with each transmit beam 205).

[0098] In some examples, network entity 105-a may indicate the number of reference signals for UE 115-a to report (e.g., by parameter values). nrofReportedRS (Set to greater than 1), and group-based beam reporting can be disabled via RRC configuration (e.g., where the parameter) groupBasedBeamReporting (Set to "Disabled"). Therefore, UE 115-a can report... nofReportedRS CRI or SSBRI (e.g., in a single report to network entity 105-a). In some examples, network entities can enable group-based beam reporting via RRC configuration (e.g., where parameters...). groupBasedBeamReporting (Set to "Enabled"). In such examples, UE 115-a can report the number of two CRIs or SSBRIs. nofReportedGroups(For example, the number of RRC configurations). For instance, UE 115-a can select one resource from each of two configured resource sets, and UE 115-a can simultaneously receive resources from each group from both configured resource sets. This group-based beamforming can be applied to SU-MIMO frequency division multiplexing (FDM) or space division multiplexing (SDM) because UE 115-a can report the resources that UE 115-a can use simultaneously.

[0099] In some examples, the L1 reporting quantity may include RSRP or SINR. For example, for RSRP-based beam selection, UE 115-a can select two different transmit beams 205 that can individually have the highest RSRP (e.g., in transmit beams 205-a to 205-f). However, RSRP-based beam selection may not take into account the correlation between the selected beams. For SINR-based beam selection, UE 115-a can select two transmit beams 205 that can individually have the highest SINR (e.g., in transmit beams 205-a to 205-f). However, SINR-based beam selection may not include the interaction (e.g., interference) between the selected beams. For example, UE 115-a can select transmit beams 205-b and 205-c, and can calculate the SINR associated with each of transmit beams 205-b and 205-c separately relative to the corresponding (e.g., pre-configured) Interference Measurement Resource (IMR), but may not calculate the SINR of each beam generated by the other beam.

[0100] Based on beam management procedures (e.g., reported RSRP or SINR), network entity 105-a can configure new CSI-RS resources (e.g., with multiple antenna ports and transmit beam 205). Network entity 105-a can request CSI feedback from UE 115-a based on the configured CSI-RS resources. UE 115-a can then send a CSI report conditional on CRI (e.g., including rank indicator (RI), layer indicator (LI), pre-decoder matrix index (PMI), and via...). cri-RI-LI-PMI-CQI The CSI report may include one or more report quantities associated with one or more transmit beams 205. In other words, the CSI report may include one or more report quantities associated with one or more transmit beams 205. In some examples, the CRI used for CSI reporting may include a relatively larger number of antenna ports (e.g., more than one or two ports) than the CRI used for beam management.

[0101] In some cases, beam management and CSI-based beam selection procedures may not allow for higher-rank (e.g., greater than rank 2) SU-MIMO. For example, UE 115-a may select a beam via the beam management procedure without considering how the beam is related or without considering rank conditions (e.g., the rank achievable by the selected beam). Therefore, UE 115-a may not identify the rank deficiency associated with the selected beam until CSI acquisition is performed. That is, UE 115-a may determine during CSI acquisition that the achievable rank of the selected beam is less than the target achievable rank (e.g., greater than rank 2), and UE 115-a may restart the beam selection procedure to select a less relevant beam.

[0102] Therefore, the techniques described herein enable UE 115-a to jointly perform beam management and CSI indication during L1 reporting. For example, based on L1 measurements from multiple individual resources or transmit beams 205, UE 115-a can determine the preferred combination of beams. For example, for a wireless communication system with two x-pol panels at each of UE 115-a and network entity 105-a, UE 115-a can measure the beamformed channel as... (For example, having a send panel) j Transmit beam and on the receiving panel i The receiving beam at the location As an illustrative example, an effective rank 4 MIMO channel This can be observed from the matrix by UE 115-a, as illustrated in Equation 1.

[0103] (1)

[0104] As described in reference to Equation 1, and It can be a first receiving beam 210 and a second receiving beam 210 (for example, receiving beam 210-a and receiving beam 210-b, respectively). and It can be a first transmit beam 205 and a second transmit beam 205 (for example, transmit beam 205-d and transmit beam 205-e, respectively). It can be achieved by using a receiving beam. and transmit beam Observed physical channels. In some examples, This can be referred to as a pre-beamforming channel.

[0105] In some respects, UE 115-a can be based on effective MIMO channels. (It is based on a single measurement) Singular value decomposition (SVD) is used to select and The SVD of an effective MIMO channel allows UE 115-a to determine the effective rank of the MIMO channel. In some examples, UE 115-a can receive simultaneously and (For example, for group-based reporting). UE 115-a can be jointly selected. and as well as and To obtain the highest overall performance for each combination of transmit beam 205 and receive beam 210 (e.g., according to the... , , and Related RSRP, SINR, CQI, PMI, and rank (can be achieved).

[0106] In some respects, UE 115-a can identify reporting metrics (e.g., rules for reporting) to identify combinations of transmit beam 205 and receive beam 210 that produce higher channel quality (e.g., based on SINR, RSRP, etc.) and have relatively low correlation compared to some other beam pairs (e.g., producing higher rank-achievable SU-MIMO communication). That is, to determine the preferred combination of both transmit beam 205 and receive beam 210, UE 115-a can report a new reporting quantity MI, which can be defined according to Equation 2.

[0107] (2)

[0108] As described with reference to Equation 2, SNR can be an SNR value assumed in the reporting configuration or according to defined rules, I can be an identity matrix, and The reachable rank assumption can be either specified in the reporting configuration or indicated by defined rules. A pair of transmit beams 205 and a pair of receive beams 210 that result in a higher MI metric may be less relevant and therefore associated with a higher reachable rank compared to a pair of transmit beams 205 and a pair of receive beams 210 that result in a lower MI metric. UE115-a can indicate the new reporting metric MI to network entity 105-a, and network entity 105-a can use the new reporting metric to perform further CSI reporting.

[0109] In order to correctly characterize the effective channel matrix For the off-diagonal terms, UE 115-a can use the same receive beam 210 for each transmit beam 205. That is, the effective channel matrix... Each row can be associated with the same receive beam 210, and the effective channel matrix Each column can be associated with the same transmit beam. Therefore, the configuration for receiving the reference signal can instruct UE 115-a to use the same receive beam 210 (e.g., similar to the configuration and UE behavior when SINR is the configured reporting metric).

[0110] In order to choose and UE 115-a can measure the effective channel from each transmit beam 205 using each receive beam 210. Accordingly, network entity 105-a can transmit reference signals multiple times via each transmit beam 205. That is, in the CSI-RS resource set configuration, repetition can be set to "on". In a CSI-RS resource set where repetition is set to "on", network entity 105-a can transmit in different OFDM symbols via resources having the same transmit beam 205. In some cases, when repetition is set to "on" for a CSI-RS resource set, UE 115-a may not report CRI. Repetition can be enabled if the reporting amount is set to RSRP, SINR, or "none". In some examples, if UE 115-a is configured with a reporting amount set to RSRP or SINR, and the measurement resource has repetition set to "on", then UE 115-a can target resources with a resource set (e.g., defined by parameters) nrofPorts Each CSI-RS resource is configured with the same number of ports (e.g., one or two ports).

[0111] To facilitate UE 115-a reporting MI, network entity 105-a can configure a new reporting quantity consisting of multiple CRIs, MI, one or more broadband coefficient values ​​based on the reported CRI settings, and RSRP values ​​(e.g., a single RSRP value) of the broadband coefficients based on the reported CRIs. This reporting can be applied to multiple CSI-RS resources or resource sets configured as measurement resources in the reporting settings. UE 115-a can calculate MI based on an SNR reference assumption, MIMO rank sum and / or one or more broadband coefficient values ​​with effective channel SVD decomposition (e.g., optimal or preferred SVD pre-decoding). In some examples, UE 115-a may determine MI without based on any PMI or RI assumptions (e.g., different from broadband CQI). In some examples, if network entity 105-a configures UE 115-a with three or more CRIs in the same reporting configuration, UE 115-a can report CRIs and / or IDs associated with CSI resources. UE 115-a can send reports to network entity 105-a based on this configuration (e.g., indicating MI metric, RSRP value and / or one or more bandwidth coefficients).

[0112] UE 115-a can enable RSRP i The calculation is an average over multiple receive ports (e.g., one or two receive ports) and the bandwidth used to receive the reference signal. The one or more bandwidth coefficients can be one or more weights describing how network entity 105-a can scale each transmit beam 205. For example, Network entity 105-a can be described as being able to transmit beams. The ratio of the transmitted power. That is, network entity 105-a can apply a bandwidth factor to scale the power of each transmitted beam 205 by a corresponding value. α This allows UE 115-a to select a higher-quality transmit beam 205 within its eigendomain (e.g., based on water-filling technology). In some examples, this one or more bandwidth coefficients can be... The form makes Therefore, the reported RSRP can be conditional on the bandwidth factor. That is, UE 115-a can calculate RSRP as a weighted sum of RSRP measurements. .

[0113] The MI metric calculated using the broadband coefficient can be relatively more accurate than the MI metric calculated without the broadband coefficient (e.g., due to the consideration of beam scaling). UE 115-a can be accordingly modified to calculate the MI using the broadband coefficient according to Equation 3.

[0114] (3)

[0115] In some examples, network entity 105-a may utilize one or more bandwidth factors to configure UE 115-a (e.g., to reduce computation at UE 115-a). For example, network entity 105-a may send values ​​applicable to the bandwidth factors. p- i finite set k The instructions. As an illustrative example, network entity 105-a can be configured with UE 115-a using a coefficient value table such as Table 1.

[0116]

[0117] Table 1

[0118] In some examples, network entity 105-a may instruct UE 115-a whether to report the broadband coefficient in the report. Therefore, UE 115-a can send a report with or without the broadband coefficient based on this instruction. In some examples, if network entity 105-a instructs UE 115-a not to report the broadband coefficient, UE 115-a may average the reported RSRPs (e.g., calculate RSRP assuming equal broadband coefficients). In some examples, the report sent by UE 115-a may include metrics (e.g., MI, RSRP) against the CRI in descending order of the respective calculated RSRPs. For example, UE 115-a may report a first CRI with the highest RSRP, followed by a second CRI with the second highest RSRP, and so on. UE 115-a may also map each corresponding reported CRI to the corresponding next broadband coefficient (e.g., the next broadband coefficient not yet reported) based on sequential positioning (e.g., in descending order of the respective calculated RSRPs). In other words, UE 115-a can map the first CRI to the first broadband coefficient, the second CRI to the second broadband coefficient, and so on (e.g., for broadband coefficients stacked sequentially, such as those in Table 1). The feedback overhead associated with reporting broadband coefficients can be... Where K is the number associated with the number of MIMO layers used by UE 115-a, CRI is the number of CRIs reported by the UE, and the non-zero coefficient N ZC This represents the number of possible values ​​for the bandwidth factor. As an illustrative example, if UE 115-a communicates using rank-4 MIMO, then UE 115-a can report K = three bandwidth factors. If UE 115-a can use eight possible bandwidth factor values, then UE 115-a can use three bits to report N. ZC .

[0119] Based on reports received from UE 115-a (e.g., reports indicating one or more MI metric values, RSRP, and / or bandwidth coefficients), network entity 105-a can configure new multi-port CSI-RS resources. CSI-RS resources can be based on MI metric values ​​defined in the reports. For example, network entity 105-a can configure CSI-RS resources using transmit beam 205 associated with a relatively high MI metric. In some examples, the QCL source for each of the multiple ports of the multi-port CSI-RS resource can be derived from the original CSI-RS configuration (e.g., a CSI-RS resource configuration repeatedly set to "on") and the one or more bandwidth coefficient values. In some examples, one or more demodulation reference signals (DM-RS) can be QCLed with the reported CRI (e.g., the CRI reported in the enhanced CSI report). Based on the weights or PMI of one or more reports, the QCL DM-RS can act as a source reference signal and pre-decoder for UE 115-a. In some examples, network entity 105-a may indicate to UE 115-a whether the bandwidth coefficients of the one or more reports have been applied. UE 115-a may then perform CSI reporting based on the indication of whether the one or more bandwidth coefficients have been applied.

[0120] In some aspects, to facilitate MI reporting, network entity 105-a may send an enhanced CSI-RS resource configuration to UE 115-a. Each resource in the enhanced CSI-RS resource configuration may include two ports (e.g., H port and V port). Network entity 105-a may additionally send a reporting configuration with new reporting quantities (e.g., MI). The reporting configuration may indicate an SNR reference and / or a MIMO rank hypothesis. Based on the CSI-RS resource configuration, UE 115-a may measure one or more reference signals from each transmit beam in transmit beam 205 via each receive beam in receive beam 210 and determine the MI metric. UE 115-a may send an enhanced CSI report (e.g., a single report or a two-part report) indicating the MI metric and / or one or more bandwidth coefficients. Network entity 105-a may determine a new set of CSI-RS resources based on the enhanced CSI-RS report from UE 115-a. Network entity 105-a can indicate a new CSI-RS resource set to UE 115-a, and UE 115-a can measure and report one or more other CSI metrics (e.g., PMI, CQI) in the supplementary CSI report based on the new CSI-RS resource set. (See relevant technical references.) Figure 3 – Figure 5 To describe in further detail.

[0121] In some examples, network entity 105-a may configure one or more resource settings, resource sets, or resources within or separately from the reporting configuration. In some examples, repetition may not be enabled initially. In such examples, UE115-a may perform UE-side beamfinding (e.g., based on a new reporting quantity MI). In some examples, the resource configurations, resource transmissions, measurements, reporting configurations, reports, etc., described herein may occur simultaneously (e.g., in parallel), in different order timelines, or according to different timelines.

[0122] Figure 3 An example of a signaling diagram 300 for a multi-beam MI supporting one or more aspects of this disclosure is shown. Signaling diagram 300 may implement aspects of wireless communication system 100 or wireless communication system 200, or may be implemented by these aspects. For example, signaling diagram 300 may include UE 115 (e.g., UE 115-b) and network entity 105 (e.g., network entity 105-b), which may be as referenced... Figure 1 Examples of the corresponding devices described.

[0123] As illustrated in reference signaling diagram 300, network entity 105-b can configure multiple resource configurations 305 (e.g., resource settings) and reporting configurations 310 (e.g., reporting settings) for UE 115-b to determine the beam ( This combination of beams may produce relatively higher channel quality and achievable rank than some other beam combinations. For example, network entity 105-b can send resource configuration 305-a, resource configuration 305-b, etc. to UE 115-b via resource configuration 305-N. In some examples, each resource configuration 305 may have a transmit beam. Different combinations. That is, each CSI-RS resource setting can have two resource sets with duplicates enabled, and each resource set... i A network entity 105--b can be used to transmit beams. Resources for transmission. For example, resource configuration 305-k may include a first resource set 350-a indicating multiple resources for beam 345-a (e.g., where repetition is set to "on"), and a second resource set 350-b indicating multiple resources for beam 345-b (e.g., where repetition is set to "on"), such that UE 115-b can use each pair of received beams of UE 115-b to measure each pair of transmitted beams. Each resource set 350 may have the same number of resources (e.g., more than one resource). In some examples, the described techniques can be extended to multiple resource sets with repetition enabled.

[0124] Network entity 105-b can send multiple report configurations 310 to UE 115-b (e.g., report configuration 310-a, report configuration 310-b, etc. up to report configuration 310-N), each report configuration corresponding to (e.g., linked to) a resource configuration 305. The multiple report configurations 310 can instruct UE 115-b to report a new amount of MI (e.g., parameters). cri- RSRP-MI ).

[0125] At step 315, network entity 105-b may transmit CSI-RS according to resource configuration 305. At step 320, UE 115-b may receive and measure CSI-RS. To receive CSI-RS, UE 115-b may apply the same QCL type D reference signal assumption used for receiving the k-th non-zero power (NZP) CSI-RS resource in resource set 350-b to receive the k-th NZP CSI-RS resource in resource set 350-a. UE 115-b may accordingly utilize multiple receive beams to measure each pair of transmit beams configured in each resource configuration 305 to determine the resource settings used for configuration (e.g., using...). A pair of receiving beams (specific resource configuration 305) ).

[0126] For example, at step 325, network entity 105-b may send a request to UE 115-b indicating a specific reporting configuration 310 corresponding to a specific resource configuration 305. That is, network entity 105-b may send a request to link to the reporting settings. k The UE 115-b can accordingly calculate and determine the transmit beam pair with the configured transmit beam and the receive beam pair (e.g., with a specific resource configuration identifier (ID)). The associated MI metric. Additionally or alternatively, UE 115-b may determine one or more bandwidth factors associated with a specific resource configuration 305, and may calculate the RSRP conditioned on those one or more bandwidth factors (e.g., a single RSRP), as referenced. Figure 2 As described.

[0127] At step 330, UE 115-b may send a feedback report to network entity 105-b based on a specific reporting configuration 310. This feedback report may indicate the calculated MI metric, RSRP, one or more bandwidth coefficients, or some combination thereof. In some examples, network entity 105-b may request UE 115-b to report the bandwidth coefficients.

[0128] In some examples, at step 335, network entity 105-b may send a CSI-RS resource set associated with a resource configuration ID (e.g., the ID of resource configuration 305 for which UE 115-b reports MI). In some examples, the CSI-RS resource set may be duplicated. UE 115-b may measure CSI-RS via the CSI-RS resource set using QCL assumptions derived from the original resource configuration 305 associated with the resource configuration ID and / or one or more bandwidth coefficients. At step 340, UE 115-b may send a CSI report based on the measured CSI-RS. For example, UE 115-b may send a CSI report indicating the PMI and / or CQI calculated based on the measured CSI-RS.

[0129] Figure 4 An example of a signaling diagram 400 for a multi-beam MI supporting one or more aspects of this disclosure is shown. Signaling diagram 400 may implement aspects of wireless communication system 100, wireless communication system 200, or signaling diagram 300, or may be implemented by these aspects. For example, signaling diagram 400 may include UE 115 (e.g., UE 115-c) and network entity 105 (e.g., network entity 105-c), which may be as referenced... Figure 1 Examples of the corresponding devices described.

[0130] As illustrated in reference signaling diagram 400, network entity 105-c can configure multiple resource configurations 405 (e.g., resource settings) and a single reporting configuration 410 (e.g., reporting settings) for UE 115-c to determine the beam ( This combination of beams may produce relatively higher channel quality and achievable rank than some other beam combinations. For example, network entity 105-c can send resource configuration 405-a, resource configuration 405-b, etc. to UE 115-c via resource configuration 405-N. In some examples, each resource configuration 405 may have a transmit beam. Different combinations. That is, each CSI-RS resource setting can have two resource sets with duplicates enabled, and each resource set... i A network entity 105--c can be used to transmit beams. Resources for transmission. For example, resource configuration 405-k may include a first resource set 450-a indicating multiple resources for beam 445-a (e.g., where repetition is set to "on"), and a second resource set 450-b indicating multiple resources for beam 445-b (e.g., where repetition is set to "on"), such that UE 115-c can use each pair of receive beams of UE 115-c to measure each pair of transmit beams. Each resource set 450 may have the same number of resources (e.g., more than one resource). In some examples, the described technique can be extended to multiple resource sets with repetition enabled.

[0131] Network entity 105-c can send a single report configuration 410 to UE 115-c that corresponds to all resource configurations 405 (e.g., linked to all resource configurations). Report configuration 410 can instruct UE 115-c to report a new amount of MI (e.g., parameters). cri-RSRP-MI ).

[0132] At step 415, network entity 105-c may transmit CSI-RS according to resource configuration 405. At step 420, UE 115-c may receive and measure CSI-RS. To receive CSI-RS, UE 115-c may apply the same QCL type D reference signal assumption used for receiving the k NZP CSI-RS resource in resource set 450-b to receive the k NZP CSI-RS resource in resource set 450-a. UE 115-c may accordingly utilize multiple receive beams to measure each pair of transmit beams configured in each resource configuration 405 to determine the resource settings used for configuration (e.g., for...). A pair of receiving beams (specific resource configuration 405) ).

[0133] For example, at step 425, network entity 105-c may send a request to UE 115-c indicating a specific resource configuration 305. That is, network entity 105-c may send a request for a link to the resource configuration. k The UE 115-c can accordingly calculate and determine the transmit beam pair with the configured transmit beam and the receive beam pair (e.g., with a specific resource configuration ID). The associated MI metric. Additionally or alternatively, UE 115-c may determine one or more bandwidth factors associated with a specific resource configuration 405, and may calculate the RSRP conditioned on those one or more bandwidth factors (e.g., a single RSRP), as referenced. Figure 2 As described. In some examples, UE 115-c can determine the MI metric autonomously (e.g., without receiving a request from network entity 105-c).

[0134] At step 430, UE 115-c may send a feedback report to network entity 105-c based on reporting configuration 410. This feedback report may indicate the calculated MI metric, RSRP, one or more bandwidth factors, or some combination thereof. In some examples, network entity 105-c may request UE 115-c to report the bandwidth factor. In some examples (e.g., if network entity 105-c does not indicate a specific resource configuration 405 for UE 115-c to report MI), UE 115-c may report the calculated MI metric associated with the beam selected by UE 115-c (e.g., the beam with the lowest MI metric and / or the highest RSRP). The feedback report may additionally indicate the resource setting ID (e.g., parameter) of the specific resource configuration 405 or the resource configuration 405 associated with the beam selected by UE 115-c. CSI-ResourceConfigId ) to specify preferred transmission beam pairs .

[0135] In some examples, at step 435, network entity 105-c may send a CSI-RS resource set associated with a resource configuration ID (e.g., the ID of resource configuration 405 for which UE 115-c reports MI). In some examples, the CSI-RS resource set may be duplicated. UE 115-c may measure CSI-RS via the CSI-RS resource set using QCL assumptions derived from the original resource configuration 405 associated with the resource configuration ID and / or one or more bandwidth coefficients. At step 440, UE 115-c may send a CSI report based on the measured CSI-RS. For example, UE 115-b may send a CSI report indicating the PMI and / or CQI calculated based on the measured CSI-RS.

[0136] Figure 5 An example of a signaling diagram 500 for a multi-beam MI, supporting one or more aspects of this disclosure, is shown. Signaling diagram 500 may implement aspects of wireless communication system 100, wireless communication system 200, signaling diagram 300, or signaling diagram 400, or may be implemented by these aspects. For example, signaling diagram 500 may include UE 115 (e.g., UE115-d) and network entity 105 (e.g., network entity 105-d), which may be as referenced... Figure 1 Examples of the corresponding devices described.

[0137] As illustrated in reference signaling diagram 500, network entity 105-d can configure multiple resource configurations 505 (e.g., resource settings) and a single reporting configuration 510 (e.g., reporting settings) for UE 115-d to determine the beam ( This combination of beams may produce relatively higher channel quality and achievable rank than some other beam combinations. For example, network entity 105-d may send resource configuration 505-a and resource configuration 505-b to UE 115-d. In some examples, each resource configuration 505 may have multiple combinations of transmit beams. That is, each CSI-RS resource setting may have multiple resource sets 550 with duplicate enabled, and each resource set... i A network entity 105--d can be used to transmit beams. The resources used for transmission. That is, each resource set 550 in resource configuration 505-a can be designated for a specific transmission beam. The resources, and each resource set 550 in resource configuration 505-b can be designated for a specific transmit beam. Resources.

[0138] For example, resource configuration 405-a may include a first resource set 550-a indicating multiple resources for beam 545-a, a second resource set 550-b indicating multiple resources for beam 545-b, and so on, up to a resource set 550-n indicating multiple resources for beam 545-c. Resource configuration 405-b may include a first resource set 550-d indicating multiple resources for beam 545-d, a second resource set 550-e indicating multiple resources for beam 545-e, and so on, up to a resource set 550-m indicating multiple resources for beam 545-f. Therefore, UE 115-c can use each pair of received beams of UE 115-c to measure each pair of transmitted beams. Each resource configuration 505-a and resource configuration 505-b may have the same number of resource sets 550, and each resource set 550 may have the same number of resources (e.g., more than one resource).

[0139] Network entity 105-d can send a single report configuration 510 to UE 115-d corresponding to (e.g., linked to) these two resource configurations 505. Report configuration 510 can indicate a new reporting amount (e.g., parameters) for UE 115-d to report MIs. cri-RSRP-MI In some examples, the described techniques can be extended to a larger number of x-pol transmit and receive panels (e.g., more than two) at UE 115-d and network entity 105-d. For example, network entity 105-d can configure UE 115-d using more than two resource configurations 505 associated with a single reporting configuration 510. When extended to multiple resource settings, UE 115-d can report as many CRIs as the number of resource settings (e.g., the number of resource configurations 505).

[0140] At step 515, network entity 105-d may transmit CSI-RS according to resource configuration 505. At step 520, UE 115-d may receive and measure CSI-RS. To receive CSI-RS, UE 115-d may apply the same QCL type D reference signal assumption used for receiving the k NZP CSI-RS resource in resource set 550-b to receive the k NZP CSI-RS resource in resource set 550-a. UE 115-d may accordingly utilize multiple receive beams to measure each pair of transmit beams configured in resource configuration 505 to determine one or more transmit beam pairs. One or more receiving beams ( (e.g., in each resource configuration 505).

[0141] For example, at step 525, network entity 105-d may send a request to UE 115-d to report MI for each resource configuration 505. That is, network entity 105-d may send a request for CSI feedback for one or more CRIs (e.g., transmit beam pairs) linked to resource configuration 505-a and one or more resource sets 550 in resource configuration 505-b. UE 115-d may accordingly calculate and configure transmit beams and one or more determined receive beams (…). The MI metric for each associated resource configuration 505. Additionally or alternatively, UE 115-d may determine one or more bandwidth factors associated with each resource configuration 505, and may calculate the RSRP for each resource configuration 505 conditioned on the one or more bandwidth factors, as referenced. Figure 2 As described. In some examples, UE 115-d can autonomously determine the MI metric (e.g., without receiving a request from network entity 105-d).

[0142] At step 530, UE 115-d may send a feedback report to network entity 105-d based on reporting configuration 510. This feedback report may indicate the calculated MI metric, RSRP, the one or more bandwidth coefficients, CRIs from each resource configuration in resource configuration 505 (e.g., two different CRIs, each associated with one of the calculated MI metrics), or some combination thereof. In some examples, network entity 105-d may request UE 115-d to report the bandwidth coefficients. In some examples (e.g., if network entity 105-d does not indicate a specific CRI for UE 115-d to report MI), UE 115-d may report the calculated MI metric associated with the beam selected by UE 115-d (e.g., the beam with the lowest MI metric and / or the highest RSRP). These two different CRIs may be associated with the beam selected by UE 115-d to specify the preferred transmission beam pair for each resource configuration 505. .

[0143] In some examples, at step 535, network entity 105-d may send a CSI-RS resource set with duplicate enabled. UE 115-d may measure CSI-RS via the CSI-RS resource set using QCL assumptions derived from the original resource configuration 505 associated with the resource configuration ID and / or one or more bandwidth coefficients. At step 540, UE 115-d may send a CSI report based on the measured CSI-RS. For example, UE 115-d may send a CSI report indicating the PMI and / or CQI calculated based on the measured CSI-RS.

[0144] Figure 6 An example of a process flow 600 for a multi-beam MI supporting one or more aspects of this disclosure is shown. Process flow 600 may implement, or be implemented by, aspects of wireless communication system 100, wireless communication system 200, signaling diagram 300, signaling diagram 400, or signaling diagram 500. For example, process flow 600 may include UE 115 (e.g., UE 115-e) and network entity 105 (e.g., network entity 105-e), which may be as referenced... Figure 1 Examples of the corresponding devices described.

[0145] In the following description of process flow 600, operations between UE 115-e and network entity 105-e may be sent in a different order than the example shown. Some operations may also be omitted from process flow 600, and other operations may be added to process flow 600. Furthermore, although some operations or signaling are shown to occur at different times for discussion purposes, these operations may actually occur simultaneously.

[0146] At 605, UE 115-e can receive control signaling from network entity 105-e indicating multiple resource set configurations and at least one reporting configuration. This control signaling may instruct repeating for one or more first transmit beams in a transmit beam set for a first resource set and one or more second transmit beams in a transmit beam set for a second resource set. For example, the first resource set configuration may instruct beam repeating for transmits via a first beam for the first resource set and via a second beam for the second resource set. Additionally or alternatively, the first resource set configuration may instruct beam repeating for transmits via a first beam for the first resource set, and the second resource set configuration may instruct beam repeating for transmits via a second beam for the second resource set.

[0147] In some examples, the control signaling can instruct UE 115-e to report MI metrics associated with the first and second beams (e.g., and one or more receive beams of UE 115-a). For example, network entity 105-a can request MI metrics via at least one reporting configuration.

[0148] In some examples, the at least one report configuration may include multiple report configurations, each corresponding to a specific resource set configuration among the multiple resource set configurations. In some examples, the at least one report configuration may include a single report configuration. In some examples, the multiple resource set configurations may include a first resource set configuration and a second resource set configuration.

[0149] In some examples, at 610, network entity 105-e may send a second control signaling to UE 115-e indicating a plurality of predefined broadband coefficient values ​​for UE 115-e to select from. These predefined broadband coefficient values ​​may represent a weighted average of the transmit power of a transmit beam set. UE 115-e may use these broadband coefficients, for example, to calculate RSRP or MI.

[0150] At point 615, UE 115-e can monitor the transmission of a first reference signal via a first transmit beam and the transmission of a second reference signal via a second transmit beam. UE 115-e can monitor the first reference signal transmission according to a first resource set configuration, and can monitor the second reference signal transmission according to either the first resource set configuration or the second resource set configuration (e.g., via resources defined by the first and second resource set configurations). Network entity 105-e can transmit the first reference signal transmission and the second reference signal transmission via the first transmit beam and the second transmit beam, respectively.

[0151] At 620, network entity 105-e may send a request to UE 115-e instructing UE 115-e to send a measurement report. This request may specify a report configuration ID associated with one of the at least one report configurations. For example, if the at least one report configuration is multiple report configurations, the request may specify the use of the first report configuration among the multiple report configurations.

[0152] At 625, network entity 105-e may send a request to UE 115-e instructing UE 115-e to report one or more broadband coefficients. In some examples, the one or more broadband coefficients may include one or more predefined broadband coefficient values ​​from a set of predefined broadband coefficient values.

[0153] At 630, UE 115-e may send a measurement report to network entity 105-e (e.g., according to at least one of the at least one reporting configurations). The measurement report may indicate a first MI metric based on measurements of a first reference signal and / or a second reference signal. The measurement report may indicate RSRP based at least in part on one or more broadband coefficients associated with the first or second transmit beam (e.g., from the one or more predefined broadband coefficients). The measurement report may include one or more predefined broadband coefficients (e.g., according to a request to report broadband coefficients). In some examples, UE 115-e may send the measurement report in response to a request (e.g., according to the indicated reporting configuration).

[0154] In some examples, the measurement report may indicate a first resource set configuration among the plurality of resource set configurations. The first resource set configuration may be associated with a preferred beam pair among the plurality of beam pairs associated with the plurality of resource set configurations (e.g., including one or both of a first transmit beam and a second transmit beam). UE 115-e may determine the preferred beam pair based at least in part on a first MI metric or one or more additional MI metrics.

[0155] In some examples (e.g., if the multiple resource set configurations include a first resource configuration and a second resource configuration), the measurement report may indicate a first MI metric associated with the first resource configuration and a second MI metric associated with the second resource configuration. The first and second MI metrics may be associated with one or more preferred beam pairs of the first and second resource set configurations. UE 115-e may determine the one or more preferred beam pairs based at least in part on the first and second MI metrics.

[0156] At 635, UE 115-e may receive a second control signaling instructing a CSI-RS resource set from network entity 105-e based on the measurement report. For example, the CSI-RS resource set may instruct UE 115-e to receive one or more additional reference signals via a first beam and / or a second beam based on a first MI metric.

[0157] At 640, network entity 105-e may transmit one or more CSI-RS via one or more resources in the CSI-RS resource set, and UE 115-e may monitor one or more CSI-RS via one or more resources in the CSI-RS resource set. At 645, UE 115-e may send a second measurement report (e.g., a CSI-RS report) to network entity 105-e, which indicates one or more of channel measurements, CQI, PMI, RI, or one or more other measurements based on CSI-RS. In some examples, channel measurements, CQI, PMI, RI, etc., may be for a first transmission beam and / or a second transmission beam.
