[0059] Some wireless communications systems may support user equipment (UE) -initiated beam reports. That is, a UE may be able to initiate a beam report to a network entity without having received a request for a beam report from the network entity. The UE may initiate the beam report based on different events or triggers. For example, a UE may determine that a new candidate beam may have a measured value that is a given threshold above or below than a corresponding measured value of a current beam (this may be referred to as Event 7) . Such a determination may be made by the UE based on the UE measuring sets of reference signals associated with the beams or associated with respective transmission configuration indicator (TCI) states of the beams. However, some events that may trigger a UE-initiated beam report may not be well-defined. For example, a UE may use some “best” beam or some “worst” beam in a current set of beams as a comparison beam for determining if a new beam could replace a beam in the current set of beams. However, the UE may not be able to determine a “best” or “worst” beam, and the network entity may not have an indication of which beams to replace, if multiple new beams exceed a threshold associated with a “best” beam or a “worst” beam.
[0060] Further, to perform a measurement procedure for UE-initiated beam reporting, the UE may use some resources associated with reference signals related to the different beams, or TCI states. In some cases, a UE may maintain some threshold quantity (e.g., a maximum quantity) of resources, component carriers, or reference signals for the UE to use to perform multiple functions, which may include UE-initiated beam reporting. However, there may not be a method for a UE to indicate a threshold quantity of resources, reference signals, or component carriers associated with UE-initiated beam reporting to a network entity.
[0061] The techniques described herein may support a network entity to configure a UE for detecting event triggers. In some implementations, a network entity may specify triggering aspects for UE-initiated beam reports such that the UE may identify “best” and “worst” beams in current sets, and the UE may report new beams to the network entity. For example, the UE may be configured by the network entity with one or more quality thresholds. A UE may detect a beam trigger event if a quality of a new beam exceeds the quality of a current beam, or an associated activated TCI state, by an associated quality threshold of the one or more quality thresholds. The current beam, used for comparison, may be the “best” or “worst” beam of the set of current beams. In some cases, the network entity may configure the UE such that the “best” or “worst” beam of the set of current beams may correspond to the beam with the highest or lowest RSRP, respectively. Additionally, or alternatively, the “best” or “worst” beam of the set of current beams may be the beam mapped to the highest or lowest value of a series of consecutive values, respectively. That is, the network entity may configure the UE, where the configuration may indicate that the beams being used by the UE, associated with TCI states, may be mapped to consecutive values, such as 1–8 (e.g., 1 may be the beam with the best quality and 8 may be the beam with the worst quality) . Based on the configuration, the UE may send a beam report to the network entity indicating the new beam, or multiple new beams, as well as current beams to replace. For example, the UE may report the new beams and may report the current beams, or TCI states, to be replaced. Additionally, or alternatively, the UE may report the beams with the highest quality of the new beams and the current beams (e.g., unreported current beams should be replaced with the reported new beams) .
[0062] Further, the techniques described herein may support the UE to report, to the network entity, a capability indicating threshold quantities of resources, reference signals, or component carriers for the UE to use for detecting beam event triggers associated with UE-initiated beam reporting. In some implementations, the UE may indicate, to the network entity, one or more threshold quantities associated with reference signals for event detection in UE-initiated beam reporting, where the threshold quantities may be related to resources, component carriers, frequencies, reference signals, or any combination thereof. Additionally, or alternatively, the UE may report, one or more threshold quantities of resources associated with reference signals for multiple functions at one or more frequency ranges, such as beam management, beam failure detection (BFD) , radio link management (RLM) , path loss measurements, new beam detection, or any combination thereof. The UE may include, in the capability report related to threshold quantities for reference signals for the multiple functions, a quantity of resources associated with reference signals for UE-initiated beam reporting at an associated one or more frequency ranges. That is, the UE may report one or more threshold quantities associated with reference signals for multiple functions, including the event detection for UE-initiated beam reporting. Based on the reported threshold quantities, the network entity may allocate resources to the UE.
[0063] Aspects of the disclosure are initially described in the context of wireless communications systems and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to UE-initiated beam report configurations.

In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0066] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0067] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a 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 a UE 115. As another example, a 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 yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0068] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via backhaul communication link (s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication link (s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0069] One or more of the network entities 105 or network equipment 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 NodeB, an eNodeB (eNB) , a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0070] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105) , such as an integrated access and 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, a network entity 105 may include one or more of a central unit (CU) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an 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) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0071] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may 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 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 a DU 165 and an 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 multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0072] In some wireless communications systems (e.g., the wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0073] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support UE-initiated beam report configurations as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0074] A 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 the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A 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, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0075] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0076] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105) .
[0077] The communication link (s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0078] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0079] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques 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 resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity 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 higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0080] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
[0081] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0082] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0083] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0084] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0085] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0086] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication 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 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.
[0087] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0088] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the 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 as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0089] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from 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 the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0090] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0091] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a 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, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0092] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may 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 may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0093] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0094] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network entity 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entity 105 or UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0095] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0096] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by 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 receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The 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 a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0097] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link (s) 125, a D2D communication link 135) . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0098] In some implementations, a network entity 105 may configure a UE 115 for detecting beam trigger events related to UE-initiated beam reporting. In some implementations, a network entity 105 may specify triggering aspects for UE-initiated beam reports such that the UE 115 may identify “best” and “worst” beams in current sets, and the UE 115 may report new beams to the network entity 105. For example, the UE 115 may be configured by the network entity 105 with one or more quality thresholds. A UE 115 may detect a beam trigger event if a quality of a new beam exceeds the quality of an activated TCI state, associated with a current beam, by an associated quality threshold of the one or more quality thresholds. The current beam, used for comparison, may be the “best” or “worst” beam of the set of current beams. In some cases, the network entity 105 may configure the UE 115 such that the “best” or “worst” beam of the set of current beams may correspond to the beam with the highest or lowest RSRP, respectively. Additionally, or alternatively, the “best” or “worst” beam of the set of current beams may be the beam mapped to the highest or lowest value of a series of consecutive values, respectively. That is, the network entity 105 may configure the UE 115, where the configuration may indicate that the beams being used by the UE 115, associated with activated TCI states, may be mapped to consecutive values, such as 1–8, where 1 may be the beam with the best quality and 8 may be the beam with the worst quality. Based on the configuration, the UE 115 may send a beam report to the network entity 105 indicating the new beam, or multiple new beams, as well as current beams to replace. For example, the UE 115 may report the new beams and may report the current beams, or activated TCI states, to be replaced. Additionally, or alternatively, the UE 115 may report the beams with the highest quality of the new beams and the current beams (e.g., unreported activated TCI states should be updated or replaced with the reported new beams) .
[0099] Further, the techniques described herein may support the UE 115 to report, to the network entity 105, a capability indicating threshold quantities of resources, reference signals, or component carriers for the UE to use for detecting beam event triggers associated with UE-initiated beam reporting. In some implementations, the UE 115 may indicate, to the network entity, one or more threshold quantities associated with reference signals for event detection in UE-initiated beam reporting, where the threshold quantities may be related to resources, component carriers, frequencies, reference signals, or any combination thereof. Additionally, or alternatively, the UE 115 may report one or more threshold quantities of resources associated with reference signals for multiple functions at one or more frequency ranges, such as beam management, BFD, RLM, path loss measurements, new beam detection, or any combination thereof. The UE 115 may include, in the capability report related to threshold quantities for reference signals for the multiple functions, a quantity of resources associated with reference signals for UE-initiated beam reporting at an associated one or more frequency ranges. That is, the UE 115 may report one or more threshold quantities associated with reference signals for multiple functions, including the event detection for UE-initiated beam reporting. Based on the reported threshold quantities, the network entity may allocate resources to the UE 115.
[0100] FIG. 2 shows an example of a wireless communications system 200 that supports UE-initiated beam report configurations in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement, or be implemented by, aspects of the wireless communications system 100. For example, the wireless communications system 200 may include network entity 105-a and UE 115-a, which may be examples of corresponding devices as described herein, including with reference to FIG. 1. The techniques described herein in the context of the wireless communications system 200 may support methods for the network entity 105-a to configure the UE 115-a for event detection and UE-initiated beam reporting, as well as support methods for the UE 115-a to report threshold quantities for references signals supported by the UE 115-a for UE-initiated beam reporting.
[0101] In some implementations, wireless communications system 200 may support UE-initiated beam reporting. That is, the UE 115-a may initiate a beam report regarding beams 210, and associated beams 205, to the network entity 105-a, without receiving a request or any prompting from the network entity 105-a. UE-initiated beam reporting may also be referred to as event-driven beam management. For example, a UE 115-amay detect a beam event trigger related to one or more beams 210, which may trigger the UE 115-a to transmit a beam report, rather than the network entity 105-a triggering transmission of a beam report. UE-initiated beam reporting may reduce overhead and latency, among other benefits.
[0102] To facilitate UE-initiated beam reporting or beam managements, the UE 115-a may use CSI measurement and reporting configuration frameworks associated with other forms of beam management. In some cases, UE-initiated beam reporting may rely on a unified TCI state. That is, the UE 115-a may assume that downlink and uplink TCI states may be related. For example, each beam 205 and beam 210 may be associated with a TCI state. A downlink beam 205-a may have an associated uplink beam 210-a, which both may be associated with the same TCI state. In some examples, UE-initiated beam reporting may be implemented for specific frequency ranges or bands (e.g., FR1, FR2) or transmission-reception point (TRP) architectures (e.g., single TRP (sTRP) , multi-TRP (mTRP) ) for intra-cell and inter-cell beam management. At least some uplink signaling content and procedures may facilitate fast beam switching for wireless communications system 200. In some cases, specific media or containers may be designed for beam reporting to facilitate UE-initiated or event-driven beam management and beam reporting.
[0103] Different events may trigger beam reporting in UE-initiated beam reporting. For example, if a quality of a current beam 210 falls below a threshold (e.g., Event 1) , the UE 115-a may initiate a beam report. In some examples, the UE 115-a may initiate a beam report if the quality of at least one new beam 230 becomes a threshold value better than a reference signal derived from an activated TCI state, or a current beam 210 and the associated beam 205 (e.g., Event 7) . The current beam 210 may be any beam 210 (e.g., 210-a, 210-b) within a current beam set, such as the beam 210 with the best quality or the beam 210 with the worst quality (e.g., the “M-th” best quality) . That is, the current beams 210 may be ordered based on their quality, and the network entity 105-a may configure the UE 115-a to determine which current beam 210 (e.g., activated TCI state) to use (e.g., “M” may be configured) as a comparison beam for event detection. In some cases, the UE 115-a may be configured via radio resource control (RRC) signaling. The configuration of the UE 115-a may be subject to a capability of the UE 115- (e.g., in some examples, the UE 115-a may not support Event 7 detection, or may indicate a single candidate value) . In some examples, the UE 115-a may initiate a beam report after a threshold quantity of events occur (e.g., Event 2) . For example, a new beam 230-a may exceed a current beam’s 210 quality by a threshold value a configurable quantity of times within a configurable time window. This may be subject to a capability of the UE 115-a. One or more events may use the same design as Event 2 (e.g., an event occurs some quantity of times within a time window before a beam report is initiated) , and may be of lower priority than Event 2 instances.
[0104] In some cases, a beam trigger event (e.g., Event 1, Event 2, Event 7) may be associated with a counter or a timer. For example, a timer may define a detection window, within which a UE 115-a may detect a beam trigger event, or a quantity of beam trigger events, before transmitting a beam report. Additionally, or alternatively, a counter may track the quantity of beam trigger events. After a threshold quantity of beam trigger events, the UE 115-a may initiate a beam report. For example, a beam trigger event that may be configured with the design of Event 2 may maintain a counter, a timer, or both to track quantities of beam trigger events within detection windows.
[0105] In some implementations, to support defined triggering and reporting aspects, such as for Event 7 detection, the network entity 105-a may output, to the UE 115-a via a communication link 215, an indication of a beam report configuration 225. The beam report configuration 225 may include one or more quality thresholds associated with event detection. Further, the beam report configuration 225 may indicate, via the beam report configuration an activated TCI state (e.g., current beam 210 and associated beam 205) to use for comparison in Event 7 detection. That is, the network entity 105-a may indicate to the UE 115-a, via beam report configuration 225 (e.g., RRC signaling) , one or more activated TCI states to use for comparison with possible new beams 230 (e.g., 230-a) . The network entity 105-a may indicate for the UE 115-a to compare new beams 230 to a beam 210 within the set of current beams. For example, the beam report configuration 225 may indicate for the UE 115-a to compare new beams 230 with the current beam 210 with the “best” quality or the current beam 210 with the “worst” quality. The quality of a beam 205 or a beam 210 may be based on the reference signal received power (RSRP) of reference signals associated with a beam 205 or a beam 210. That is, a beam 210 associated with reference signals with the highest RSRP of all the current beams 210 may be the beam 210 of the highest, or best, quality. The beam 210 associated with reference signals with the lowest RSRP of all of the current beams 210 may be the beam 210 of lowest, or worst, quality. The network entity 105-a may configure the UE 115-a to compare new beams 230 to the best or worst quality beam 210 of the set of current beams 210, and the UE 115-a may perform some measurements or may utilize some previous measurements or information to determine which of the set of current beams 210 may correspond to the current beam 210 with the best or worst quality, such as by performing measurements of the RSRP associated with current beams 210 based on reference signals transmitted via associated beams 205.
[0106] In some cases, the UE 115-a may label each beam 210 with an integer based on their respective qualities. For example, a beam 210-a may have the best quality, or highest associated RSRP, and may be labeled as 1. A beam 210-b may have the worst quality, or lowest associated RSRP, and may be labeled as 8. The network entity 105-amay indicate which beam to use for the event detection by indicating which integer to use, which the UE 115-a may map to a specific beam or activated TCI state. For example, the network entity 105-a may indicate to use the beam 210-a by indicating to use the beam 210 labeled with 1 (e.g., the 1st quality beam) . Thus, the network entity 105-a may indicate which beam 210 to use for comparison with new beams 230, as described further with reference to FIG. 3.
[0107] In accordance with detecting a beam trigger event (or a threshold quantity of beam trigger events) , the UE 115-a may transmit a beam report. The UE 115-a may use resources to transmit the beam report. In some implementations, the resources for transmission of the beam report may be dynamically scheduled by the network entity 105-a (e.g., Mode A) . For example, the UE 115-a may transmit a physical uplink control channel (PUCCH) , which may be one-bit or multi-bit, to request a resource on a second uplink channel in order to transmit the beam report. In some cases, the request may be transmitted via uplink control information (UCI) or a scheduling request (SR) . In some examples, a new UCI format or type may be defined for transmission of the request. After obtaining the PUCCH, the network entity 105-a may output a downlink control information (DCI) . The UE 115-a may detect that the DCI may be a format to indicate resources for the second uplink channel for transmission of the beam report. Then, the UE 115-a may transmit the beam report via the second uplink channel. The second uplink channel may be a PUCCH, a physical uplink shared channel (PUSCH) , or both. In some implementations, the UE 115-a capable of supporting UE-initiated beam reporting may also support this method of resource request.
[0108] In some implementations, the resources for transmission of the beam report may be pre-configured for a second uplink channel (e.g., Mode B) . For example, the network entity 105-a may pre-configure the UE 115-a with a second uplink channel for transmission related to UE-initiated beam reporting, or may activate a pre-configured channel at the UE 115-a. The UE 115-a may transmit a first PUCCH, which may be one-bit or multi-bit, to the network entity 105-a to notify the network entity 105-a of the beam report. In some cases, the notification may be a UCI, such as a new UCI type or format, or an SR. After transmitting the notification, the UE 115-a may transmit the beam report via the second uplink channel. The second uplink channel may be a PUCCH, a PUSCH, or both. In some cases, the notification may occur in a separate reporting instance to the beam report. In some implementations, for either Mode A or Mode B, the network entity 105-a may transmit feedback (e.g., ACK or NACK) for any combination of the transmissions from the UE 115-a. Further, beam reporting may be supported across component carriers (CCs) for both modes.
[0109] In some implementations, the UE 115-a may measure reference signals, such as channel state information reference signals (CSI-RS) , across multiple resources for multiple purposes or functions. The UE 115-a may transmit, via a communication link 215, some capability signaling 220 to the network entity 105-a indicating threshold quantities (e.g., maximum quantities) of resources, reference signals, component carriers, or the like related to reference signals for measurements associated with UE-initiated beam reporting. For example, the UE 115-a may indicate a threshold quantity (e.g., maximal number) of CSI-RS resources across all CCs, and across a master cell group (MCG) or a secondary cell group (SCG) for specific radio connectivities (e.g., new radio (NR) –dual connectivity (DC) ) , for the UE 115-a to monitor the quality of a physical downlink control channel (PDCCH) (e.g., maxNumberCSI-RS-BFD) . In some implementations, there may be a threshold value that may be signaled in the capability signaling 220 (e.g., 16) . In some cases, the UE 115-a may include the threshold quantity of CSI resources across all CCs for a frequency band (e.g., FR1, FR2) . The indicated threshold quantity may apply in all frequency ranges within the frequency band. For example, if the UE 115-a includes the field in an FR1 band, it may set the same value in all FR1 bands. In some implementations, the UE 115-a may support a threshold quantity of resources equal to the threshold value of the value associated with the frequency band, but may support, at most, the threshold quantity for a frequency band within serving cells associated with that frequency band. In some cases, reporting the threshold quantity of resources across all CCs may be based on the frequency band. For example, the UE 115-a may report this capability for one frequency band (e.g., FR2) , but may not for a different frequency band (e.g., FR1) .
[0110] Additionally, or alternatively, the UE 115-a may indicate whether the UE supports mTRP beam failure recovery based on two BFD reference signal (BFD-RS) sets (e.g., mTRP-BFR-twoBFD-RS-Set-r17) . In some examples, the UE 115-a may indicate a threshold quantity of BFD-RS resources (e.g., supported measured BFD-RS) per set per bandwidth part (BWP) (e.g., maxBFD-RS-resourcesPerSetPerBWP-r17) . Additionally, or alternatively, the UE 115-a may indicate a threshold quantity of CCs per band configured for beam failure recovery (e.g., including special cell beam, secondary cell, or mTRP beam failure recovery) (e.g., maxBFR-r17) . Additionally, or alternatively, the UE 115-a may indicate a threshold quantity of BFD-RS resources across two BFD-RS sets per BWP (e.g., maxBFD-RS-resourcesAcrossSetsPerBWP-r17) .
[0111] Additionally, or alternatively, the UE 115-a may indicate a threshold quantity of resources (e.g., synchronization signal blocks (SSB) , CSI-RS, CSI interference measurements (IM) resources) for beam management, pathloss measurement, BFD, RLM, new beam identification, or any combination thereof for one frequency range that the UE may support (e.g., maxTotalResourcesForOneFreqRange-r16) . In some implementations, the threshold quantity of resources may include resources for UE-initiated beam reporting. In some examples, the UE 115-a may indicate a threshold quantity of resources configured for measurements within a slot across all CCs in one frequency range for an RSRP (e.g., L1-RSRP) measurement, SINR (e.g., L1-SINR) measurement, path loss measurement, BFD, RLM, new beam identification, UE-initiated beam reporting, or any combination thereof (e.g., maxNumberResWithinSlotAcrossCC-OneFR-r16) . In some cases, the reference slot duration may be the shortest slot duration defined for the reported frequency band (e.g., FR1, FR2) supported by the UE 115-a. Additionally, or alternatively, the UE 115-a may indicate a threshold quantity of resources configured across all CCs in one frequency range for an RSRP (e.g., L1-RSRP) measurement, SINR (e.g., L1-SINR) measurement, path loss measurement, BFD, RLM, new beam identification, UE-initiated beam reporting, or any combination thereof (e.g., maxNumberResAcrossCC-OneFR-r16) .
[0112] Additionally, or alternatively, the UE 115-a may indicate a threshold quantity of resources (e.g., SSB, CSI-RS, CSI-IM resources) for beam management, pathloss measurement, BFD, RLM, and new beam identification across frequency ranges (both FR1 and FR2) that the UE supports (e.g., maxTotalResourcesForAcrossFreqRanges-r16) . In some implementations, the threshold quantity of resources may include resources for UE-initiated beam reporting. This indication may include a indication of a threshold quantity of resources (e.g., maxNumberResWithinSlotAcrossCC-AcrossFR-r16) configured for measurement within a slot across all CCs across all frequency ranges for an RSRP (e.g., L1-RSRP) measurement, SINR (e.g., L1-SINR) measurement, path loss measurement, BFD, RLM, new beam identification, or any combination thereof. In some cases, the reference slot duration may be the shortest slot duration defined for the reported frequency band (e.g., FR1, FR2) supported by the UE 115-a. Additionally, or alternatively, this indication may include an indication of a threshold quantity of resources configured across all CCs across all frequency ranges supported by the UE 115-a for an RSRP (e.g., L1-RSRP) measurement, SINR (e.g., L1-SINR) measurement, path loss measurement, BFD, RLM, new beam identification, or any combination thereof (e.g., maxNumberResAcrossCC-AcrossFR-r16) .
[0113] In order to report the threshold quantities of resources to the network entity 105-a via the capability signaling 220, the UE 115-a may determine or count quantities of resources or threshold quantities of resources associated with the various functions or procedures. For example, a resource used for one or more procedures for BFD or RLM, as well as UE-initiated beam reporting, the resource may be counted as one. If a resource is used for one or more procedures associated with new beam identification, path loss measurement (e.g., PL-RS) , or RSRP measurement (e.g., L1-RSRP) , each may count as one (e.g., add one) . In some cases, RSRP measurement may include reports with some parameters configured (e.g., reports with reportQuanitty set to ssb-Index-RSRP, cri-RSRP, or with reportQuantity set to none and CSI-RS-ResourceSet with trs-Info not configured) . In some examples, a resource may be used for SINR measurement. The resource may be counted ‘N’ times if the resource is referred to by one or more parameters ‘N’ times (e.g., by one or more CSI reporting settings with reportQuantity-r16 = ssb-Index-SINR-r16 or cri-SINR-r16. In some cases, for reference signals configured for new beam identification, the resources may be counted towards a total quantity of resources (e.g., always counted) regardless of a beam failure event. In some cases, the reference signals (e.g., the “configured to measure” reference signals) may be counted within the duration of a reference slot in which the corresponding reference signals may be transmitted. In some cases, the threshold quantity of resources within a slot across all CCs across frequency ranges may count for active BWP and may not count for inactive BWP, while the threshold quantity of resources across CCs across frequency ranges may count both active and inactive BWP.
[0114] The network entity 105-a may consider the capability signaling 220, as well as other parameters or features (e.g., beamManagementSSB-CSI-RS, maxNumberCSI-RS-BFD, maxNumberSSB-BFD, maxNumberCSI-RS-SSB-CBD) when configuring resources for beam management, pathloss measurement, BFD, RLM and new beam identification across a frequency range or across multiple frequency ranges. In some cases, the signaled values in the capability signaling 220 may apply to a shortest slot duration defined in any frequency bands supported by the UE 115-a.
[0115] As noted, the UE 115-a may include threshold quantities associated with reference signals for UE-initiated beam reporting in the reported threshold quantities, as described herein. Additionally, or alternatively, the UE 115-a may indicate threshold quantities associated with reference signals for UE-initiated beam reporting in parameters specifically for UE-initiated beam reporting. For example, the UE 115-amay indicate a threshold quantity of reference signals for UE-initiated beam reports across all CCs in the capability signaling 220, as described further with reference to FIG. 5.
[0116] FIG. 3 shows an example of a wireless communications system 300 that supports UE-initiated beam report configurations in accordance with one or more aspects of the present disclosure. The wireless communications system 300 may implement, or be implemented by, aspects of the wireless communications systems 100 or 200. For example, the wireless communications system 300 may include network entity 105-b and UE 115-b, which may be examples of corresponding devices as described herein, including with reference to FIGs. 1 and 2. The techniques described herein in the context of the wireless communications system 300 may support methods for the network entity 105-b to configure the UE 115-b for event detection and UE-initiated beam reporting.
[0117] In some wireless communications systems 300, the UE 115-a may be configured by the network entity 105-a (e.g., via RRC signaling) with various parameters related to UE-initiated beam reporting. For example, the network entity 105-a may transmit, via downlink 305, an indication of configuration 315 (e.g., beam report configuration 315) . The configuration 315 may indicate quality thresholds associated with activated TCI states, or current beams, at the UE 115-a. The quality thresholds may be, in particular, associated with a beam quality measurement of the current beams at the UE 115-b, such as for an Event 7 instance, as described with reference to FIG. 2. That is, if a new beam exceeds a current beam by a quality threshold of the quality thresholds, the UE 115-b may initiate a beam report. The configuration may also indicate which current beam the UE 115-b may use for comparison with a new beam. For example, the UE 115-b may compare a new beam with the quality of a current beam, or activated TCI state, with the “M-th” best quality. The value of M, indicating the comparison beam, may be configured by the network entity 105-a, or may be indicated via the configuration 315.
[0118] In some implementations, the network entity 105-b may configure, or indicate for, the UE 115-b to use the current beam with the “best” quality or the current beam with the “worst” quality. In some cases, a “best” quality may be associated with a “first” quality. That is, the activated TCI state with the greatest (e.g., best, first) quality, which may be the beam associated with the greatest RSRP, may be used to compare with a new beam. For example, the UE 115-b may detect a beam trigger event (e.g., Event 7) if an RSRP associated with a new beam exceeds the greatest RSRP associated with a current beam, or activated TCI state, by a quality threshold of the quality thresholds. In other cases, a “worst” quality may be associated with a “last” quality. That is, the activated TCI state with the lowest (e.g., worst, last) quality, which may be activated TCI state associated with the lowest RSRP, may be used to compare a new beam. For example, the UE 115-b may detect a beam trigger event (e.g., Event 7) if an RSRP associated with a new beam exceeds the lowest RSRP of a current beam, or activated TCI state, by a quality threshold of the quality thresholds.
[0119] In some implementations, the network entity 105-b may indicate an integer M within a range (e.g., 1 to 8) to indicate which activated TCI state, or current beam, to use for comparison. For example, the UE 115-b may map a range of consecutive integers to the activated TCI states, or current beams, such that the lowest integer may correspond to a beam with the best quality and the highest integer may correspond to a beam with the worst quality, or vice versa. In some cases, there may be a limit on the quantity of activated TCI states (e.g., eight) . In some examples, the UE 115-b may have a quantity (e.g., eight) of possible activated TCI states, but may have less than the quantity of TCI states activated (e.g., less than eight current beams) . The network entity 105-b may indicate for the UE 115-b to use the largest integer, which may correspond to the quantity of possible activated TCI states. However, the UE 115-b may not have the quantity of possible TCI states activated. Instead, the UE 115-b may use the beam mapped to the largest integer of activated TCI states. For example, the UE 115-b may have eight possible TCI states (e.g., configured TCI states) , but may use five activated TCI states, mapped to integers 1–5. The network entity 105-b may indicate for the UE 115-b to use the activated TCI state corresponding to the integer 8 for comparison with new beams. Because there may be no beam mapped to an integer 8, the UE 115-b may determine to use the activated TCI state mapped to the integer 5 for comparison, instead. That is, the UE 115-b may trigger a beam report if a new beam becomes quality threshold better than the beam labeled with, or mapped to, integer 5, rather than a beam labeled with integer 8, since no such beam may exist.
[0120] In some implementations, in accordance with receiving the configuration 315 and detecting a beam trigger event based on the configuration 315, the UE 115-b may transmit, via uplink 310, an indication 320 notifying the network entity 105-b of transmission of a beam report 325. The indication 320 may include a request for resources for transmission of the beam report 325 or, additionally or alternatively, may notify the network entity 105-b of the transmission of the beam report 325 (e.g., Mode A, Mode B) , as described further with reference to FIG. 2.
[0121] After receiving the configuration 315 and detecting a beam trigger event based on the configuration 315, the UE 115-b may transmit, via the uplink 310, the beam report 325. The beam report 325 may indicate current beams to be replaced and new beams to replace the current beams with. The beam report 325 may be formatted such that the network entity 105-b may determine which activated TCI states, or currents beams, are the “best” , “worst” , or “M-th” best quality, as described herein. That is, the configuration 315 may indicate to the UE 115-b to use a current beam with some quality, and the UE 115-b may determine which current beam matches the criteria configured by the network entity 105-b. The UE 115-b may indicate to the network entity 105-b which of the current beams may match the configured criteria. Further, in some cases, the UE 115-b may detect that multiple new beams may be associated with one or more beam trigger events. That is, multiple new beams may exceed the quality of the comparison beam by the threshold quality. If the UE 115-b reports multiple new beams, the UE 115-b may also report which other current beams, or activated TCI states, may be replaced.
[0122] In some implementations, the UE 115-b may report, in the beam report 325, the beams with the highest quality from a super set of reference signals. The super set of reference signals may include reference signals associated with new beams and reference signals associated with current beams, or activated TCI states. For example, the UE 115-b may report the beams with the highest RSRPs of the current beams and possible new beams via the beam report 325. The network entity 105-b may determine which of the current beams to replace with the higher quality new beams based on the beam report 325. For example, the UE 115-b may have eight activated TCI states. The UE 115-b may send the beam report 325 to the network entity 105-b, where the beam report 325 may indicate five current beams and three new beams. The network entity 105-b may determine to replace the three unreported current beams, associated with activated TCI states, with the three new beams. The network entity 105-b may transmit response messages 330 to the UE 115-b to indicate to replace the unreported activated TCI states with the three new beams. In some cases, the UE 115-b may report the beams associated highest quality reference signals of all configured TCI states, which may include possible new beams and current beams (e.g., activated TCI states) . The beam report 325 may thus implicitly indicate the highest quality beams between the current beams and the new beams. In some cases, the UE 115-b may catenate a set of reference signals associated with new beams with a set of reference signals associated with the activated TCI states (e.g., current beams) to form the super set. That is, the UE 115-b may generate a list of the reference signals by adding the new beams to the current beams, and the network entity 105-b may determine which current beams to replace based on the beam report 325.
[0123] In some implementations, the UE 115-b may report the highest quality beams of the new beams (from a set of measurement reference signals associated with the new beams) and may additionally report which activated TCI states to replace in the beam report 325. In some examples, the UE 115-b may indicate a bitmap of a length dependent on the quantity of activated TCI states (e.g., up to 8) , where up to N bits may be set to 1, where N may be a quantity of new beams to report. A bit set to 1 may indicate that the corresponding activated TCI state may be replaced with a new beam. The beam report 325 may include reference signal IDs associated with the new beams, reference signal metrics associated with the new beams, and the bitmap. In some cases, the UE 115-b may be configured to also report reference signal metrics for the activated TCI states to be replaced. In this way, the UE 115-b may indicate to the network entity 105-b which current beams to replace with new beams. In some examples, the network entity 105-b may analyze the metrics in the beam report 325 to determine whether to replace or maintain the current beams.
[0124] In some implementations, the network entity 105-b may output, via downlink 305, response messages 330 in response to receiving the beam report 325. The response messages 330 may indicate whether the UE 115-b is to maintain or replace one or more current beams with one or more new beams. In some cases, the response messages 330 may include a medium access control-control element (MAC-CE) , such as a TCI activation MAC-CE. In some cases, the response messages 330 may indicate for the “M-th” highest quality activated TCI state to remain the same after new TCI activation. That is, the comparison beam for an Event 7 instance may not be replaced. In some examples, the UE 115-b may reset a counter of event instances, reset a timer defining a detection window for an event 7 detection, or both based on receiving the response messages 330. In other examples, the UE 115-b may resume (e.g., maintain, restart) the counter or timer for event detection. In other cases, the response messages 330 may indicate for the “M-th” highest quality activated TCI state to be replaced with a new beam (e.g., updated to a new TCI state) . The UE 115-b may reset the counter of event instance, reset the timer defining the detection window, or both based on receiving the response messages 330 (e.g., when the new TCI activation takes effect) .
[0125] FIG. 4 shows an example of a process flow 400 that supports UE-initiated beam report configurations in accordance with one or more aspects of the present disclosure. The process flow 400 may implement, or be implemented by, aspects of the wireless communications systems 100, 200, or 300. For example, the process flow 400 may include network entity 105-c and UE 115-c, which may be examples of corresponding devices as described herein, including with reference to FIGs. 1–3. The techniques described herein in the context of the process flow 400 may support methods for the network entity 105-c to configure the UE 115-c for event detection and UE-initiated beam reporting.
[0126] At 405, the UE 115-c may receive, and the network entity 105-c may output, one or more control signals indicating a beam report configuration, where the beam report configuration may indicate one or more quality thresholds associated with beam quality measurement of a set of beams of the UE 115-c, where the set of beams may correspond to a set of TCI states for the UE 115-c. In some cases, the beam report configuration may indicate a set of consecutive values associated with the set of TCI states, where the set of consecutive values may be mapped to the set of TCI states in accordance with the beam quality measurement.
[0127] In some implementations, at 410, the UE 115-c may measure one or more reference signals, the one or more reference signals associated with the set of TCI states, a TCI state associated with the first beam, or any combination thereof, where measurement of the one or more reference signals may include the beam quality measurement, as described at 405.
[0128] At 415, the UE 115-c may detect a beam trigger event, where the beam trigger event may indicate that a first beam quality of a first beam exceeds a second beam quality of a second beam by a quality threshold of the one or more quality thresholds, as described at 405, where the first beam may be different than each of the set of beams. For example, the first beam may be a new beam, as described further with reference to FIGs. 1–3. In some cases, the UE 115-c may detect the beam trigger event based on the beam quality measurement, as described at 405 and 410. In some cases, a set of measurement values associated with the beam quality measurement may correspond to the set of beams and the second beam quality of the second beam may be associated with a measurement value of the set of measurement values. The measurement value may include a largest measurement value or a smallest measurement value of the set of measurement values, and detection of the beam trigger event may be in accordance with the measurement value associated with the second beam quality of the second beam. In some examples, the beam report configuration, as discussed at 405, may indicate that the second beam quality of the second beam may be associated with the largest measurement value or that the second beam quality of the second beam may be associated with the smallest measurement value.
[0129] In some cases, as described at 405, the beam report configuration may indicate a set of consecutive values associated with the set of TCI states, where the set of consecutive values may be mapped to the set of TCI states in accordance with the beam quality measurement. The UE 115-c may detect the beam trigger event at 415 in accordance with a value of the set of consecutive values associated with a TCI state of the set of TCI states, the TCI state associated with the second beam. In some examples, a first quantity of the set of consecutive values may be greater than a second quantity of the set of TCI states, where a third quantity of one or more consecutive values of the set of consecutive values may be mapped to the second quantity of the set of TCI states in accordance with the beam quality measurement, the third quantity the same as the second quantity.
[0130] At 420, the UE 115-c may transmit, and the network entity 105-c may obtain, via a first uplink channel, an indication of transmission of a beam report, as described further at 425, via a second uplink channel different than the first uplink channel.
[0131] At 425, the UE 115-c may transmit, and the network entity 105-c may obtain, a beam report indicating the first beam based on detection of the beam trigger event, as described at 415. In some cases, the UE 115-c may transmit the beam report, via the second channel, based on transmission of the indication, as described further at 420. In some cases, the UE 115-c may transmit, in accordance with the beam trigger event, the beam report indicating a second set of beams, where the second set of beams comprises a first one or more beams of the set of beams, one or more new beams including the first beam, or any combination thereof, where the second set of beams are based on multiple sets of reference signals associated with the set of TCI states. In some cases, the UE 115-c may transmit, in accordance with the beam trigger event, the beam report indicating a second set of beams, where the second set of beams comprises one or more beams of the set of beams and one or more new beams including the first beam, where the second set of beams are based on multiple sets of reference signals associated with the set of TCI states.
[0132] In some implementations, at 430, the UE 115-c may receive, and the network entity 105-c may output, in accordance with obtainment of the beam report, as described at 425, one or more messages indicating to replace or maintain one or more beams of the set of beams with the first beam. In some cases, the UE 115-c may receive, in accordance with transmission of the beam report, as described at 425, one or more messages indicating to replace a second one or more beams of the set of beams, the second one or more beams different from the first one or more beams, with the one or more new beams. In some cases, the UE 115-c may receive, in accordance with transmission of the beam report, one or more messages indicating to replace the one or more beams of the plurality of beams with the one or more new beams.
[0133] In some implementations, at 435, the UE 115-c may update (e.g., reset or resume) a timer, counter, or both in accordance with reception of the one or more messages, as described at 430, where the counter, the timer, or both are associated with a detection window for the beam trigger event, and where detection of the beam trigger event, as described at 415 is in accordance with the counter, the timer, or both. For example, as described at 430, the one or more messages may indicate for the UE 115-c to replace one or more beams of the set of beams with the first beam. At 435, the UE 115-a may reset the counter based on receiving the one or more messages to replace one or more beams of the set of beams. In other examples, as described at 430, the one or more messages may indicate for the UE 115-c to maintain the set of beams. At 435, the UE 115-c may update (e.g., maintain or reset) the counter, the timer, or both based on receiving the one or more messages to maintain the set of beams.
[0134] FIG. 5 shows an example of a wireless communications system 500 that supports UE-initiated beam report configurations in accordance with one or more aspects of the present disclosure. The wireless communications system 500 may implement, or be implemented by, aspects of the wireless communications systems 100, 200, or 300, or process flow 400. For example, the wireless communications system 500 may include network entity 105-d and UE 115-d, which may be examples of corresponding devices as described herein, including with reference to FIGs. 1–4. The techniques described herein in the context of the wireless communications system 500 may support methods for the UE 115-d to report threshold quantities for references signals supported by the UE 115-d for UE-initiated beam reporting.
[0135] In some implementations, the UE 115-d may transmit, via uplink 510, capability signaling 515, indicating threshold quantities for reference signals, to the network entity 105-d. In some cases, the UE 115-d may indicate, via the capability signaling 515, capability parameters specific to UE-initiated beam reporting. For example, the UE 115-d may indicate, via the capability signaling 515, a threshold quantity (e.g., maximum) of reference signals, across multiple CCs (e.g., all available CCs) , as well as across MCG and SCG, for detecting events to trigger UE-initiated beam reports (e.g., maxNumberUEI-RS, maxNumberUEI-SSB) . For event 1, the threshold quantity (e.g., maxNumberUEI-RS, maxNumberUEI-SSB) may include a quantity of reference signals associated with the current beams. That is, for Event 1, the UE 115-d may measure the current beams to detect a beam trigger event. For Events 2 and 7, the threshold quantity (e.g., maxNumberUEI-RS, maxNumberUEI-SSB) may include a quantity of reference signals associated with new beams, as well as the quantity of reference signals associated with the current beams or activated TCI states. That is, for Events 2 and 7, the UE 115-d may measure the current beams, or activated TCI states, and the new beams to detect a beam trigger event.
[0136] Additionally, or alternatively, the UE 115-d may indicate a threshold quantity of resources for reference signals associated with UE-initated beam reporting based on various granularities. For example, the UE 115-d may indicate a threshold quantity of resources (e.g., measured UE-initiated beam reporting reference signal (UEI-RS) resources) associated with reference signals per set or report per BWP (e.g., maxUEI-RS-resourcesPerSetPerBWP) . Additionally, or alternatively, the UE 115-d may indicate a threshold quantity of resources associated with reference signals across events per BWP (e.g., maxUEI-RS-resourcesAcrossSetsPerBWP) . Additionally, or alternatively, the UE 115-d may indicate a threshold quantity of component carriers per frequency band that may be configured with UE-initiated beam reporting (e.g., maxUEI) .
[0137] In some implementations, the UE 115-d may include threshold quantities associated with reference signals for UE-initiated beam reporting in capability signaling 515 that may also include quantities associated with reference signals for other procedures, as described further with reference to FIG. 2. For example, the UE 115-d may include the threshold quantity of reference signals associated with UE-initiated beam reporting (e.g., maxNumberUEI-RS, maxNumberUEI-SSB) with a threshold quantity of resources (e.g., SSB, CSI-RS, or CSI-IM resources) for beam management, pathloss measurement, BFD, RLM, and new beam identification for a frequency range that the UE 115-d may support (e.g., maxTotalResourcesForOneFreqRange) . In some cases, this may include an indication of a threshold quantity of resources for measurements within a slot across all CCs within the frequency range for a RSRP (e.g., L1-RSRP) measurement, signal to interference noise ratio (SINR) (e.g., L1-SINR) measurement, pathloss measurement, BFD, RLM, new beam identification, event detection for UE-initiated beam reporting, or any combination thereof (e.g., maxNumberResWithinSlotAcrossCC-OneFR) . Additionally, or alternatively, this may include an indication of a threshold quantity of resources for measurements across all CCs within the frequency range for a RSRP (e.g., L1-RSRP) measurement, SINR (e.g., L1-SINR) measurement, pathloss measurement, BFD, RLM, new beam identification, event detection for UE-initiated beam reporting, or any combination thereof (e.g., maxNumberResAcrossCC-OneFR) .
[0138] Additionally, or alternatively, the UE 115-d may include the threshold quantity of reference signals associated with UE-initiated beam reporting (e.g., maxNumberUEI-RS, maxNumberUEI-SSB) with a threshold quantity of resources (e.g., SSB, CSI-RS, or CSI-IM resources) for beam management, pathloss measurement, BFD, RLM, and new beam identification across frequency ranges (e.g., FR1, FR2) that the UE 115-d may support (e.g., maxTotalResourcesForAcrossFreqRanges) . In some cases, this may include an indication of a threshold quantity of resources for measurements within a slot across all CCs across the frequency ranges for a RSRP (e.g., L1-RSRP) measurement, signal to interference noise ratio (SINR) (e.g., L1-SINR) measurement, pathloss measurement, BFD, RLM, new beam identification, event detection for UE-initiated beam reporting, or any combination thereof (e.g., maxNumberResWithinSlotAcrossCC-AcrossFR) . Additionally, or alternatively, , this may include an indication of a threshold quantity of resources for measurements across all CCs across the frequency ranges for a RSRP (e.g., L1-RSRP) measurement, SINR (e.g., L1-SINR) measurement, pathloss measurement, BFD, RLM, new beam identification, event detection for UE-initiated beam reporting, or any combination thereof (e.g., maxNumberResAcrossCC-AcrossFR) .
[0139] In accordance with the capability signaling 515, the network entity 105-d may output, via downlink 505, an indication of a resource allocation 520 to the UE 115-d. For example, the network entity 105-d may consider the threshold quantities (e.g., capabilities, parameters) reported by the UE 115-d in the capability signaling 515 to allocate resource for multiple functions (e.g., beam management, pathloss measurement, BFD, RLM, new beam identification, event detection for UE-initiated beam reporting, or any combination thereof) across one or more frequency ranges.
[0140] To report the threshold quantities in the capability signaling 515, the UE 115-d may determine or count the quantity of reference signals or resources. If a resource is used by the UE 115-d for one or multiple of BFD, RLM, or event detection for a UE-initiated beam report, the resource may be counted as one. In some cases, other resources may be counted differently, as described further with reference to FIG. 2.
[0141] In accordance with the resource allocation 520, the UE 115-d may measure one or more reference signals and may detect one or more beam event triggers (e.g., Event 1, Event 2, Event 7) . In accordance with detecting a beam event trigger, the UE 115-d may transmit, via the uplink 510, the beam report 525. The beam report 525 may indicate current beams, activated TCI states, new beams, or any combination thereof, based on the beam event trigger. The network entity 105-d may configure the UE 115-d with one or more threshold quantities for Event 7 detection, and may indicate a comparison beam (or activated TCI state) for Event 7 detection.
[0142] FIG. 6 shows an example of a process flow 600 that supports UE-initiated beam report configurations in accordance with one or more aspects of the present disclosure. The process flow 600 may implement, or be implemented by, aspects of the wireless communications systems 100, 200, 300, or 500, or process flow 400. For example, the process flow 600 may include network entity 105-e and UE 115-e, which may be examples of corresponding devices as described herein, including with reference to FIGs. 1–5. The techniques described herein in the context of the process flow 600 may support methods for the UE 115-e to report threshold quantities for references signals supported by the UE 115-e for UE-initiated beam reporting.
[0143] At 605, the UE 115-e may transmit, and the network entity 105-e may obtain, one or more signals indicating a capability of the UE 115-e for UE-initiated beam reporting, where the capability of the UE 115-e may indicate one or more threshold quantities for reference signals supported by the UE 115-e for UE-initiated beam reporting. In some cases, the one or more threshold quantities may include a threshold quantity of resources for reference signals across one or more component carriers, one or more sets associated with a bandwidth part, or any combination thereof. In some cases, the one or more threshold quantities may include one or more reference signals associated with a set of beams of the UE, a set of TCI states, a set of new beams, or any combination thereof. In some cases, the one or more threshold quantities may include a threshold quantity of components carriers within a band. In some cases, the one or more threshold quantities may include one or more threshold quantities of resources for one or more frequencies, one or more frequency ranges, or any combination thereof, and the one or more threshold quantities of resources may be associated with resources for beam management, pathloss management, BFD, RLM, new beam identification, event detection for UE-initiated beam reporting, or any combination thereof.
[0144] At 610, the UE 115-e may receive, and the network entity 105-e may output, an indication of a resource allocation for an event detection procedure for UE-initiated beam reporting, where the resource allocation may be in accordance with the one or more threshold quantities for reference signals supported by the UE 115-e for UE-initiated beam reporting.
[0145] At 615, the UE 115-e may perform, as part of the event detection procedure for UE-initiated beam reporting, a measurement procedure of one or more reference signals via one or more resources indicated by the resource allocation, as described at 610. In some implementations, performing the measurement procedure as part of the event detection procedure may include detecting a beam event trigger, where detection of the beam event trigger may be associated with one resource of the one or more resources.
[0146] At 620, the UE 115-e may transmit, and the network entity 105-e may obtain, a beam report indicating one or more beam measurements associated with the UE 115-e based on the event detection procedure for UE-initiated beam reporting, as described further at 615.
[0147] FIG. 7 shows a block diagram 700 of a device 705 that supports UE-initiated beam report configurations in accordance with one or more aspects of the present disclosure. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. The device 705, or one or more components of the device 705 (e.g., the receiver 710, the transmitter 715, the communications manager 720) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0148] The receiver 710 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to UE-initiated beam report configurations) . Information may be passed on to other components of the device 705. The receiver 710 may utilize a single antenna or a set of multiple antennas.
[0149] The transmitter 715 may provide a 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 UE-initiated beam report configurations) . In some examples, the transmitter 715 may be co-located with a receiver 710 in a transceiver module. The transmitter 715 may utilize a single antenna or a set of multiple antennas.
[0150] The communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be examples of means for performing various aspects of UE-initiated beam report configurations as described herein. For example, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0151] In some examples, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) . The hardware may include at least one of 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 configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure. In some examples, at least one processor and at least one memory coupled with the at least one processor may be configured to perform one or more of the functions described herein (e.g., by one or more processors, individually or collectively, executing instructions stored in the at least one memory) .
[0152] Additionally, or alternatively, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by at least one processor (e.g., referred to as a processor-executable code) . If implemented in code executed by at least one processor, the functions of the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be performed by a general-purpose processor, 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, individually or collectively, a means for performing the functions described in the present disclosure) .
[0153] In some examples, the communications manager 720 may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 710, the transmitter 715, or both. For example, the communications manager 720 may receive information from the receiver 710, send information to the transmitter 715, or be integrated in combination with the receiver 710, the transmitter 715, or both to obtain information, output information, or perform various other operations as described herein.
[0154] The communications manager 720 may support wireless communications in accordance with examples as disclosed herein. For example, the communications manager 720 is capable of, configured to, or operable to support a means for receiving one or more control signals indicating a beam report configuration, where the beam report configuration indicates one or more quality thresholds associated with beam quality measurement of a set of multiple beams of the UE, where the set of multiple beams correspond to a set of multiple transmission configuration indicator (TCI) states for the UE. The communications manager 720 is capable of, configured to, or operable to support a means for detecting a beam trigger event, where the beam trigger event indicates that a first beam quality of a first beam exceeds a second beam quality of a second beam by a quality threshold of the one or more quality thresholds, where the first beam is different than each of the set of multiple beams. The communications manager 720 is capable of, configured to, or operable to support a means for transmitting a beam report indicating the first beam based on detection of the beam trigger event.
[0155] Additionally, or alternatively, the communications manager 720 may support wireless communications in accordance with examples as disclosed herein. For example, the communications manager 720 is capable of, configured to, or operable to support a means for transmitting one or more signals indicating a capability of the UE for UE-initiated beam reporting, the capability of the UE indicating one or more threshold quantities for reference signals supported by the UE for UE-initiated beam reporting. The communications manager 720 is capable of, configured to, or operable to support a means for receiving an indication of a resource allocation for an event detection procedure for UE-initiated beam reporting, where the resource allocation is in accordance with the one or more threshold quantities for reference signals supported by the UE for UE-initiated beam reporting. The communications manager 720 is capable of, configured to, or operable to support a means for performing, as part of the event detection procedure for UE-initiated beam reporting, a measurement procedure of one or more reference signals via one or more resources indicated by the resource allocation.
