[0057] Some wireless communications may support user equipment (UE) -assisted performance monitoring. In such cases, for a single performance monitoring instance, a network entity may transmit, to a UE, multiple first reference signals via a first set of beams (e.g., Set B) . The UE may measure the first reference signals to generate a first set of actual measurements (e.g., actual signal qualities) associated with the first set of beams and may input the first set of actual measurements into a machine learning (ML) model (e.g., or artificial intelligence (AI) model) to generate (e.g., output) a set of predicted measurements (e.g., predicted signal qualities) associated with a second set of beams (e.g., Set A) . The UE may then identify, for the single performance monitoring instance, one or more predicted best beams (e.g., Top-K or Top-1 predicted best beams) from the second set of beams based on the set of predicted measurements. For example, the one or more predicted best beams may be associated with highest signal qualities out of the second set of beams (e.g., based on the set of predicted measurements) . Additionally, the UE may receive, from the network entity, multiple second reference signals via the second set of beams (e.g., Set A) and may may measure the second reference signals to generate a second set of actual measurements (e.g., actual signal qualities) associated with the second set of beams. Thus, the UE may transmit a report associated with the performance monitoring instance, where the report is indicative of at least a subset of the one or more predicted best beams, at least a subset of the set of predicted measurements, or both, relative to at least a subset of one or more actual best beams, at least a subset of the second set of actual measurements, or both.
[0058] In some cases, the network entity may transmit (e.g., may only transmit) a subset of the second set of beams, the UE may monitor for (e.g., may only monitor for) the subset of the second set of beams, or both. In such cases, at least one of the one or more predicted best beams may not be in the subset of the second set of beams. Thus, the UE may determine whether to transmit a report for the single performance monitoring instance based on whether at least a subset of the one or more predicted best beams are within the subset of the second set of beams. That is, the UE may transmit a report for the single performance monitoring instance based on at least a subset of the one or more predicted best beams being within the subset of the second set of beams. In such cases, the single performance monitoring instance may be referred to as an eligible performance monitoring instance. Conversely, the UE may refrain from transmitting a report for the single performance monitoring instance based on at least a subset of the one or more predicted best beams being outside of the subset of the second set of beams. In such cases, the single performance monitoring instance may be referred to as an ineligible performance monitoring instance. However, in some cases, the UE may transmit a single report for multiple performance monitoring instances. In such cases, the UE may be unable to determine how, or if, to report information associated with eligible performance monitoring instances, ineligible performance monitoring instances, or both.
[0059] Accordingly, techniques described herein may enable a UE to transmit a report associated with multiple performance monitoring instances based on a quantity of eligible performance monitoring instances among the multiple performance monitoring instances. For example, in some cases, the UE may receive a control message indicative of a fixed reporting window (e.g., in terms of a duration of a quantity of performance monitoring instances) and may transmit a report associated with multiple performance monitoring instances (e.g., within the reporting window) that indicates the quantity of eligible performance monitoring instances within the reporting window. Additionally, or alternatively, the UE may receive a control message indicative of a threshold quantity of eligible performance monitoring instances and may transmit a report based on the quantity of eligible performance monitoring instances (e.g., in the multiple performance monitoring instances) satisfying the threshold quantity of eligible performance monitoring instances.
[0060] In some other cases, the UE may receive a control message indicative of the fixed reporting window and the threshold quantity of eligible performance monitoring instances. In such cases, the UE may transmit a report based on either an expiration of the reporting window or based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances. That is, if the quantity of eligible performance monitoring (e.g., in the multiple performance monitoring instances) instances fails to satisfy the threshold quantity of eligible performance monitoring instances prior to expiration of the reporting window, the UE may transmit a report that indicates the quantity of eligible performance monitoring instances within the reporting window (e.g., based on expiration of the reporting window) . Conversely, if the quantity of eligible performance monitoring instances (e.g., in the multiple performance monitoring instances) satisfies the threshold quantity of eligible performance monitoring instances prior to expiration of the reporting window, the UE may transmit a report prior to expiration of the reporting window (e.g., based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances) .
[0061] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are then described in the context of a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to window-based metrics for predictive beam management for limited performance monitoring sets.
[0062] FIG. 1 shows an example of a wireless communications system 100 that supports window-based metrics for predictive beam management for limited performance monitoring sets in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0063] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. 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) .
[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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) .
[0068] 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) ) .
[0069] 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.
[0070] 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.
[0071] 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 window-based metrics for predictive beam management for limited performance monitoring sets 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) .
[0072] 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 multimedia / entertainment device (e.g., a radio, a MP3 player, or a video device) , a camera, a gaming device, a navigation / positioning device (e.g., GNSS (global navigation satellite system) devices based on, for example, GPS (global positioning system) , Beidou, GLONASS, or Galileo, or a terrestrial-based device) , a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet) ) , a drone, a robot / robotic device, a vehicle, a vehicular device, a meter (e.g., parking meter, electric meter, gas meter, water meter) , a monitor, a gas pump, an appliance (e.g., kitchen appliance, washing machine, dryer) , a location tag, a medical / healthcare device, an implant, a sensor / actuator, a display, or any other suitable device configured to communicate via a wireless or wired medium. 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.
[0073] 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.
[0074] 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) .
[0075] 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.
[0076] 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) .
[0077] 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.
[0078] 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) ) .
[0079] 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) .
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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) .
[0088] Certain aspects and techniques as described herein may be implemented, at least in part, using an AI program, such as a program that includes a ML or artificial neural network (ANN) model. An example ML model may include mathematical representations or define computing capabilities for making inferences from input data based on patterns or relationships identified in the input data. As used herein, the term “inferences” can include one or more of decisions, predictions, determinations, or values, which may represent outputs of the ML model. The computing capabilities may be defined in terms of certain parameters of the ML model, such as weights and biases. Weights may indicate relationships between certain input data and certain outputs of the ML model, and biases are offsets which may indicate a starting point for outputs of the ML model. An example ML model operating on input data may start at an initial output based on the biases and then update its output based on a combination of the input data and the weights.
[0089] ML models may be deployed in one or more devices (for example, network entities and UEs) and may be configured to enhance various aspects of a wireless communication system. For example, an ML model may be trained to identify patterns or relationships in data corresponding to a network, a device, an air interface, or the like. An ML model may support operational decisions relating to one or more aspects associated with wireless communications devices, networks, or services. For example, an ML model may be utilized for supporting or improving aspects such as signal coding / decoding, network routing, energy conservation, transceiver circuitry controls, frequency synchronization, timing synchronization channel state estimation, channel equalization, channel state feedback, modulation, demodulation, device positioning, beamforming, load balancing, operations and management functions, or security.
[0090] ML models may be characterized in terms of types of learning that generate specific types of learned models that perform specific types of tasks. For example, different types of machine learning include supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. ML models may be used to perform different tasks such as classification or regression, where classification refers to determining one or more discrete output values from a set of predefined output values, and regression refers to determining continuous values which are not bounded by predefined output values. Some example ML models configured for performing such tasks include ANNs such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs) , transformers, diffusion models, regression analysis models (such as statistical models) , large language models (LLMs) , decision tree learning (such as predictive models) , support vector networks (SVMs) , or probabilistic graphical models (such as a Bayesian network) .
[0091] The description herein illustrates, by way of some examples, how one or more tasks or problems in wireless communications may benefit from the application of one or more ML models. To facilitate the discussion, an ML model configured using an ANN is used, but it should be understood, that other types of ML models may be used instead of an ANN. Hence, unless expressly recited, subject matter regarding an ML model is not necessarily intended to be limited to an ANN solution. Further, it should be understood that, unless otherwise specifically stated, terms such “AI / ML model, ” “ML model, ” “trained ML model, ” “ANN, ” “model, ” “algorithm, ” or the like are intended to be interchangeable.
[0092] The wireless communications system 100 may support techniques that enable a UE 115 to transmit a report associated with multiple performance monitoring instances based on a quantity of eligible performance monitoring instances among the multiple performance monitoring instances, where an eligible performance monitoring instances is associated with at least a threshold quantity of one or more respective predicted best beams being within at least subset of a second set of beams. For example, in some cases, the UE 115 may receive a control message indicative of a fixed reporting window (e.g., in terms of a duration of a quantity of performance monitoring instances) and may transmit a report associated with multiple performance monitoring instances (e.g., within the reporting window) that indicates the quantity of eligible performance monitoring instances within the reporting window. Additionally, or alternatively, the UE 115 may receive a control message indicative of a threshold quantity of eligible performance monitoring instances and may transmit a report based on the quantity of eligible performance monitoring instances (e.g., in the multiple performance monitoring instances) satisfying the threshold quantity of eligible performance monitoring instances.
[0093] In some other cases, the UE 115 may receive a control message indicative of the fixed reporting window and the threshold quantity of eligible performance monitoring instances. In such cases, the UE 115 may transmit a report based on either an expiration of the reporting window or based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances. That is, if the quantity of eligible performance monitoring (e.g., in the multiple performance monitoring instances) instances fails to satisfy the threshold quantity of eligible performance monitoring instances prior to expiration of the reporting window, the UE 115 may transmit a report that indicates the quantity of eligible performance monitoring instances within the reporting window (e.g., based on expiration of the reporting window) . Conversely, if the quantity of eligible performance monitoring instances (e.g., in the multiple performance monitoring instances) satisfies the threshold quantity of eligible performance monitoring instances prior to expiration of the reporting window, the UE 115 may transmit a report prior to expiration of the reporting window (e.g., based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances) .
[0094] FIG. 2 shows an example of a wireless communications system 200 that supports UE-initiated and event-driven performance monitoring reporting for limited performance monitoring sets in accordance with one or more aspects of the present disclosure. In some cases, 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 one or more UEs 115 (e.g., a UE 115 a) and one or more network entities 105 (e.g., a network entity 105 a) , which may be examples of the corresponding devices as described herein.
[0095] Some wireless communications systems, such as the wireless communications system 200, mays support performance monitoring using UE-side ML models (e.g., AI models) . In some cases, the performance monitoring may be Type 2 performance monitoring. In such cases, a UE 115 may transmit, to a network entity 105, an indication of a capability of the UE 115 to support performance monitoring using UE-side machine learning models (e.g., UE AI / ML capability) and may additionally transmit a request for the network entity 105 to transmit a set of reference signals 205 for use by the UE 115 for performance monitoring. Thus, the network entity 105 may transmit (periodically, aperiodically, or semi-persistently) the set of reference signals 205 (e.g., based on the request) , such that the UE 115 may generate (e.g., compute) one or more performance metrics (e.g., monitoring key performance indicators (KPIs) ) based on measurements of the set of reference signals, based on an output of an ML model (e.g., AI / ML interference outcome) , or both. The UE 115 may transmit, to the network entity 105, an indication of the one or more performance metrics (e.g., information about the one or more performance metrics) and, in some cases, may receive, from the network entity 105, information associated with one or more lifecycle management (LCM) operations for the ML model (e.g., UE-side AI / ML model) based on the one or more performance metrics. Thus, the UE 115 may perform the one or more LCM operations at the UE 115. For example, the UE 115 may activate a new ML model, deactivate the previous ML model, switch ML models, perform a fallback procedure, or any combination thereof. Additionally, the UE 115 may transmit, to the network entity 105, information associated with execution of the one or more LCM operations at the UE 115.
[0096] In some other cases, the performance monitoring may be Type 1 performance monitoring. In some examples, the Type 1 performance monitoring may be NW-side performance monitoring. In such cases, a UE 115 may transmit, to a network entity 105, an indication of a capability of the UE 115 to support performance monitoring using UE-side machine learning models (e.g., UE AI / ML capability) and may additionally transmit a request for the network entity 105 to transmit a set of reference signals 205 for use by the UE 115 for performance monitoring. Thus, the network entity 105 may transmit (periodically, aperiodically, or semi-persistently) the set of reference signals 205 (e.g., based on the request) , such that the UE 115 may measure of the set of reference signals to generate a set of measurements (e.g., Layer 1 (L1) -reference signal receive power (RSRP) ) and may transmit a report (e.g., measurement report) indicating the measurements (e.g., and / or one or more reference signal indices) to the network entity 105. In such cases, the report may be configured, triggered, or both, by the network entity 105. Thus, the network entity 105 may evaluate a performance of an ML model (e.g., AI model) at the UE 115 based on the report (e.g., calculate one or more performance metrics based on the measurements) . Additionally, the network entity 105 may transmit, to the UE 115, information associated with one or more LCM operations for the ML model (e.g., UE-side AI / ML model) based on the evaluation and the UE 115 may perform the one or more LCM operations at the UE 115. For example, the UE 115 may activate a new ML model, deactivate the previous ML model, switch ML models, perform a fallback procedure, or any combination thereof. Additionally, the UE 115 may transmit, to the network entity 105, information associated with execution of the one or more LCM operations at the UE 115.
[0097] In some other examples, the Type 2 performance monitoring may be UE-assisted performance monitoring. In such cases, a UE 115 may transmit, to a network entity 105, an indication of a capability of the UE 115 to support performance monitoring using UE-side machine learning models (e.g., UE AI / ML capability) and may additionally transmit a request for the network entity 105 to transmit a set of reference signals 205 for use by the UE 115 for performance monitoring. Thus, the network entity 105 may transmit (periodically, aperiodically, or semi-persistently) the set of reference signals 205 (e.g., based on the request) , such that the UE 115 may generate (e.g., compute) one or more performance metrics (e.g., monitoring KPIs) based on measurements of the set of reference signals, based on an output of an ML model (e.g., AI / ML interference outcome) , or both, may determine an occurrence of an event (e.g., based on the one or more performance metrics) , or both. Thus, the UE 115 may transmit, to the network entity 105, a report including information associated with the one or more performance metrics, the event occurrence, or both, such that the network entity 105 may evaluate a performance of an ML model (e.g., AI model) at the UE 115 based on the report. In some cases, may receive information associated with one or more LCM operations for the ML model (e.g., UE-side AI / ML model) based on the evaluation. Thus, the UE 115 may perform the one or more LCM operations at the UE 115. For example, the UE 115 may activate a new ML model, deactivate the previous ML model, switch ML models, perform a fallback procedure, or any combination thereof. Additionally, the UE 115 may transmit, to the network entity 105, information associated with execution of the one or more LCM operations at the UE 115.
[0098] In some cases, a UE 115, such as the UE 115-a, may perform performance monitoring of beam prediction. For example, for each performance monitoring instance 225, a UE 115, such as the UE 115-a, may receive, from a network entity 105, such as the network entity 105-a, reference signals 205-a (e.g., a first set of reference signals 205) via a beam set 210-a (e.g., Set B) , where the beam set 210-a may include wide beams 215. For each performance monitoring instance 225, the UE may measure the reference signals 205-a to generate a first set of actual (e.g., measured) measurements (e.g., a first set of actual L1-RSRPs) associated with the beam set 210-a (e.g., each beam 215 in the beam set 210-a) and may input the first set of actual measurements into an ML model at the UE 115-a (e.g., AI model) to generate (e.g., output) a set of predicted measurements (e.g., a set of predicted L1-RSRPs) associated with a beam set 210-b (e.g., each beam 215 in the beam set 210-b) , where the beam set 210-b (e.g., Set A) may include narrow beams 215. Additionally, for each performance monitoring instance 225, the UE 115-a may then predict one or more best beams 215 (e.g., Top-K or Top-1 predicted best beams 215) , which may be referred to as predicted best beams 215, from the beam set 210-b based on the set of predicted measurements. For example, the one or more predicted best beams 215 may be associated with highest signal qualities out of the beam set 210-b (e.g., based on the set of predicted measurements) .
[0099] Additionally, for each performance monitoring instance 225, the UE 115-a may receive, from the network entity 105-a, reference signals 205-b via the beam set 210-b (e.g., Set A) and may may measure the reference signals 205-b to generate a second set of actual measurements (e.g., second set of actual L1-RSRPs) associated with the beam set 210-b (e.g., each beam 215 in the beam set 210-b) . In some cases, the beam prediction (e.g., generation of the set of predicted measurements) may be temporal beam prediction in which reception of the reference signals 205-a occurs prior to reception of the reference signals 205-b. In other words, reception of the reference signals 205-a may be independent of (e.g., many not overlap with) reception of the reference signals 205-b in a time domain. In some other cases (e.g., as depicted in FIG. 2) , the beam prediction may be spatial beam prediction in which reception of the reference signals 205-a (e.g., at t-2, t-1, t0, and t1) at least partially overlap in time with reception of the reference signals 205-b (e.g., at t-2+Δt, t-1+Δt, t0+Δt, and t1+Δt, respectively) . In other words, reception of the reference signals 205-a at least partially overlap with reception of the reference signals 205-b in the time domain.
[0100] Thus, the UE 115-a may transmit a report 220 (e.g., one or more reports 220) indicating one or more per-instance performance metrics associated with each performance monitoring instance 225 based on generating the second set of actual measurements. That is, each performance monitoring instance 225 may be associated with one or more respective performance metrics (e.g., per-instance performance metrics) . In some cases, the report 220 may include, for each performance monitoring instance 225, a respective indication of a prediction accuracy of the one or more predicted best beams 215 (e.g., Top-1 or Top-K predicted best beams 215) . In such cases, for each performance monitoring instance 225, the indication of the prediction accuracy (e.g., with or without margin) may be based on the UE 115-a comparing one or more respective predicted best beams 215 from the beam set 210-b to one or more respective actual best beams 215 from the beam set 210-b (e.g., based on the second set of measurements) . Additionally, or alternatively, the report 220 may include, for each performance monitoring instance 225, a respective indication of a respective first difference (e.g., L1-RSRP difference) between one or more predicted measurements (e.g., from the set of predicted measurements) associated with the one or more respective predicted best beams 215 from the beam set 210-b to one or more actual measurements (e.g., from the second set of actual measurements) associated with the one or more respective actual best beams 215 from the beam set 210-b (e.g., based on the second set of measurements) . Additionally, or alternatively, the report 220 may include, for each performance monitoring instance 225, a respective indication of a second difference (e.g., L1-RSRP difference) between one or more predicted measurements (e.g., from the set of predicted measurements) associated with the one or more respective predicted best beams 215 from the beam set 210-b to one or more actual measurements (e.g., from the second set of actual measurements) associated with the one or more respective predicted best beams 215 (e.g., one or more received beams 215 from the beam set 210-b that correspond to the one or more respective predicted best beams 215) . Additionally, or alternatively, the report 220 may include, for each performance monitoring instance 225, a respective indication of probability information of the one or more respective predicted best beams 215 to be the one or more respective actual best beams 215.
[0101] In some cases, the network entity 105-a may not transmit all beams 215 of the beam set 210-b, the UE 115-a may not monitor for all beams 215 of the beam set 210-b, or both (e.g., for a performance monitoring instance 225) . For example, if a quantity of beams 215 in the beam set 210-b (e.g., prediction set) exceeds a threshold (e.g., 128 beams or larger) , the reference signals 205-b, transmitted by the network entity 105-a, may not span the entire beam set 210-b (e.g., may not be transmitted via all beams 215 of the beam set 210-b) . In such cases, a subset of beams 215 from the beam set 210-b, which may be referred to as performance monitoring beams 215, may be available for performance monitoring. In other words, the performance monitoring beams 215 may be used to transmit the reference signals 205-b, which may be referred to as a performance monitoring set of reference signals 205-b, that are to be measured by the UE 115-g for performance monitoring, per performance monitoring instance 225. Additionally, or alternatively, even if the reference signals 205-b span the entire beam set 210-b (e.g., the entire beam set 210-b is available for measurement) , the UE 115-a may not be capable of measuring all of the reference signal 205-b to derive one or more performance metrics (e.g., due to complexity reasons) . In such cases, only a subset of the beam set 210-b may be configured for performance monitoring.
[0102] Thus, in some cases, the UE 115-a may determine whether to transmit an indication of one or more per-instance performance metrics (e.g., via a report 220) associated with a performance monitoring instance 225 based on whether a threshold quantity (e.g., at least a subset) of one or more predicted best beams 215 (e.g., associated with the performance monitoring instance 225) are within at least a subset of a beam set 210-b. That is, the UE 115-a may transmit a report 220 indicative of one or more per-instance performance metrics associated with for a performance monitoring instance 225 based on at least a subset of one or more respective predicted best beams 215 (e.g., associated with the performance monitoring instance 225) being within the subset of the beam set 210-b. In such cases, the performance monitoring instance 225 may be referred to as an eligible performance monitoring instance 225. For example, for a performance monitoring instance 225-a, the beam set 210-b (e.g., used by the UE 115-a for prediction of one or more predicted best beams 215) may include a beam 215-a, a beam 215-b, a beam 215-c, a beam 215-d, a beam 215-e, a beam 215-f, a beam 215-g, a beam 215-g, a beam 215-h, and a beam 215-j, but the subset of the beam set 210-b may include the beam 215-a, the beam 215-b, the beam 215-c, the beam 215-d, and the beam 215-c. Additionally, the UE 115-a may have previously identified (e.g., via inference outcome, via prediction) that the beam 215-a, the beam 215-c, and the beam 215-d are the predicted best beams 215. In such cases, the beam 215-a, the beam 215-c, and the beam 215-d are within the subset of the beam set 210-b, such that the UE 115-a may transmit a report 220 indicative of one or more per-instance performance metrics associated with the performance monitoring instance 225-a. In other words, the performance monitoring instance 225-a may be an eligible performance monitoring instance 225.
[0103] Conversely, the UE 115-a may refrain from transmitting an indication of one or more per-instance performance metrics (e.g., via a report 220) associated with a performance monitoring instance 225 based on at least a subset of the one or more predicted best beams 215 being outside of the at least subset of the beam set 210-b. In such cases, the performance monitoring instance 225 may be referred to as an ineligible performance monitoring instance 225. For example, for a performance monitoring instance 225-d, the beam set 210-b (e.g., used by the UE 115-a for prediction of one or more predicted best beams 215) may include a beam 215-k, a beam 215-m, a beam 215-n, a beam 215-o, a beam 215-p, a beam 215-q, a beam 215-r, a beam 215-s, and a beam 215-t, but the subset of the beam set 210-b may include the beam 215-k, the beam 215-m, the beam 215-n, the beam 215-o, and the beam 215-p. Additionally, the UE 115-a may have previously identified (e.g., via inference outcome, via prediction) that the beam 215-o, the beam 215-p, and the beam 215-r are the predicted best beams 215, however, the network entity 105-a may not have transmitted reference signals 205-b via the beam 215-r. Thus, in some cases (e.g., the threshold quantity of one or more predicted best beams 215 may be all of the one or more predicted best beams 215) , the UE 115-a may refrain from transmitting an indication of one or more per-instance performance metrics associated with the performance monitoring instance 225-d. In other words, the performance monitoring instance 225-d may be an ineligible performance monitoring instance 225.
[0104] In some cases, the UE 115-a may determine (e.g., compute) one or more performance metrics associated with multiple performance monitoring instances 225. That is, rather than transmitting one or more reports 220 (e.g., a report 220 per performance monitoring instance 225) indicating one or more per-instance performance metrics associated with each eligible performance monitoring instance 225 of multiple performance monitoring instances 225, the UE 115-a may transmit a single report 220 indicative of one or more cumulative performance metrics (e.g., window-based performance metrics) associated with the multiple performance monitoring instances 225. In some cases, the one or more performance metrics associated with the multiple performance monitoring instances 225 may be based on (e.g., a function of, an average of) the one or more per-instance performance metrics associated with each eligible performance monitoring instance 225 of multiple performance monitoring instances 225. Reporting of one or more cumulative performance metrics (e.g., window-based metrics) may reduce a frequency of transmission of performance monitoring reports 220 (e.g., a single report 220 rather than a report 220 per-performance monitoring instance) while still enabling the network entity 105-a to evaluate performance of beam prediction by the UE 115-a (e.g., UE-side AI / ML model performance) . However, when the multiple performance monitoring instances 225 includes at least one ineligible performance monitoring instance 225, the UE 115-a may be unable to determine how, or if, to consider the at least one ineligible performance monitoring instance 225 with regards to the one or more cumulative performance metrics associated with the multiple performance monitoring instances 225. Additionally, or alternatively, the network entity 105-a may be unable to determine a reliability of the one or more cumulative performance metrics based on a quantity of ineligible performance monitoring instance 225 within the multiple performance monitoring instances 225.
[0105] Accordingly, techniques described herein may enable a UE 115, such as the UE 115-a, to transmit a single report 220 associated with multiple performance monitoring instances 225 (e.g., indicative of one or more cumulative performance metrics associated with the multiple performance monitoring instances 225) based on a quantity of eligible performance monitoring instances 225 (e.g., N) among the multiple performance monitoring instances 225 (e.g., an entire set, I, of performance monitoring instances 225) . That is, the UE 115-a may determine a first set of performance monitoring instances 225 (e.g., I1) of the multiple performance monitoring instances 225 that are eligible and a second set of performance monitoring instances 225 (e.g., I2) of the multiple performance monitoring instances 225 that are ineligible, where the first set of performance monitoring instances 225 includes the quantity of eligible performance monitoring instances 225 (e.g., N) . Thus, the UE 115-a may transmit a single report 220 associated with the multiple performance monitoring instances 225 (e.g., the entire set, I, of performance monitoring instances 225) based on the quantity of eligible performance monitoring instances 225 (e.g., in the first set of performance monitoring instances 225, I1)
[0106] For example, in some cases (e.g., Option 1) , the UE 115-a may be configured with (e.g., may receive a control message indicative of) a fixed reporting window 230 (e.g., fixed window length) . In such cases, the fixed reporting window 230 may be a duration (e.g., quantity of symbols, quantity of slots, time interval, such as 500 ms) or may be a threshold quantity of performance monitoring instances 225 (e.g., such as 40) .
[0107] Thus, the UE 115-a may compute one or more cumulative (e.g., window-based) performance metrics for each reporting window 230. In such cases, the one or more cumulative performance metrics may be based on a quantity of eligible performance monitoring instances 225 within the reporting window 230. As described herein, an eligible performance monitoring instance 225 may be associated with (e.g., based on) at least a subset of one or more respective predicted best beams 215 (e.g., associated with the performance monitoring instance 225) being within a subset of the beam set 210-b. That is, a performance monitoring instance 225 may be an eligible performance monitoring instance 225 based on whether a threshold quantity of the one or more predicted best beams 215 associated with the performance monitoring instance 225 are within the subset of the beam set 210-b.
[0108] For example, in some cases, the threshold quantity of the one or more best predicted best beams 215 may include all of the one or more predicted best beams 215. In other words, a performance monitoring instance 225 may be an eligible performance monitoring instance 225 based on all of the one or more predicted best beams 215 (e.g., Top-K predicted best beams 215) associated with the performance monitoring instance 225 being within the subset of the beam set 210-b (e.g., within the performance monitoring set) . Conversely, a performance monitoring instance 225 may be an ineligible performance monitoring instance 225 based on all of the one or more predicted best beams 215 associated with the performance monitoring instance 225 failing to be within (e.g., being outside of) the subset of the beam set 210-b (e.g., less than all of the one or more predicted best beams 215 being within the performance monitoring set ) . In other words, the UE 115-a may determine the first set of performance monitoring instances 225 (e.g., I1) of the multiple performance monitoring instances 225 that are eligible (e.g., for which Top-K predicted best beams 215 for each performance monitoring instance 225 are within the performance monitoring set) and the second set of performance monitoring instances 225 (e.g., I2) of the multiple performance monitoring instances 225 that are ineligible (e.g., for which Top-K predicted best beams 215 for each performance monitoring instance 225 are not within the performance monitoring set) . Thus, the one or more cumulative performance metrics may be based on the first set of performance monitoring instances 225 that includes the quantity of eligible performance monitoring instances 225 (e.g., N) .
[0109] In such cases, the one or more cumulative performance metrics associated with the quantity of eligible performance monitoring instances 225 within the reporting window 230 may include one or more beam prediction accuracies (e.g., Top-1 and / or Top-K beam prediction accuracy with or without margin) . For example, the UE 115-a may identify (e.g., count) a subset of the eligible performance monitoring instances 225 (e.g., NP) for which a highest measured RSRP (e.g., L1-RSRP) of the one or more predicted best beams 215 of the subset of the beam set 210-b (e.g., Top-K predicted best beams) is within a margin of a measured RSRP of an actual best beam 215 of the subset of the beam set 210-b (e.g., best measured beam identifier from the performance monitoring set) . In other words, if a best predicted best beam 215 of the one or more predicted best beams (e.g., after the UE 115-a measures the one or more predicted best beams 215 and finds the best one having the highest measured RSRP) is within a margin (e.g., threshold tolerance) of an actual best beam 215 (e.g., from the performance monitoring set) , then performance degradation due to selecting the best predicted best beam 215 is tolerable (e.g., is within the threshold tolerance) , as compared to selecting the actual best beam 215 (e.g., resulting in a successful prediction event) . The UE 115-a may divide a second quantity of the subset of the eligible performance monitoring instances 225 (e.g., NP) by the quantity (e.g., total quantity) of the eligible performance monitoring instances 225 (e.g., N, a size of I1) to obtain a beam prediction accuracy (e.g., NP / N) associated with the quantity of eligible performance monitoring instances 225. Thus, the UE 115-a may transmit a report 220 indicative of the quantity of eligible performance monitoring instances (e.g., N) and the beam prediction accuracy (e.g., NP / N) .
[0110] For example, in the context of FIG. A, within the reporting window 230, the performance monitoring instance 225-a a performance monitoring instance 225-b, and a performance monitoring instance 225-c may be eligible performance monitoring instances 225 based on respective predicted best beams 215 (e.g., for each performance monitoring instance 225) being within a respective subset of the beam set 210-b. Conversely, the performance monitoring instance 225-d may be an ineligible performance monitoring beam based on the predicted best beam 215-r being outside of the subset of the beam set 210-b. In some cases, a respective subset of the beam set 210-b may be the same for each performance monitoring instance 225 in the reporting window 230 (e.g., as depicted in FIG. 2) or may be different for each performance monitoring instance 225 in the reporting window 230 (e.g., not depicted) .
[0111] Additionally, or alternatively, the threshold quantity of the one or more best predicted best beams 215 may include a quantity, N, of the one or more predicted best beams 215. In other words, a performance monitoring instance 225 may be an eligible performance monitoring instance 225 based on at least N of the one or more predicted best beams 215 (e.g., at least N of the Top-K predicted best beams 215) associated with the performance monitoring instance 225 being within the subset of the beam set 210-b. Conversely, a performance monitoring instance 225 may be an ineligible performance monitoring instance 225 based on less than N of the one or more predicted best beams 215 associated with the performance monitoring instance 225 being within the subset of the beam set 210-b. In such cases, the one or more cumulative performance metrics associated with the quantity of eligible performance monitoring instances 225 within the reporting window 230 may be indicative of one or more computed RSRP differences (e.g., statistics, such as mean or standards deviation, of computed L1-RSRP differences) . That is, the one or more computed RSRP differences may be based on (e.g., indicative of) a respective difference (e.g., for each eligible performance monitoring instance 225) between measured RSRP of the one or more (e.g., the at least N) respective predicted best beams 215 and measured RSRP of one or more respective actual best beams 215 (e.g., of the subset of the beam set 210-b) . For example, the one or more computed RSRP differences may include an average computed RSRP difference (e.g., between predicted best beams 215 and actual best beams 215) associated with the quantity of eligible performance monitoring instances 225.
[0112] Additionally, or alternatively, the threshold quantity of the one or more best predicted best beams 215 may include a best predicted best beam 215 of the one or more predicted best beams 215. In other words, a performance monitoring instance 225 may be an eligible performance monitoring instance 225 based on a best predicted best beam 215 of the one or more predicted best beams 215 (e.g., Top-1 predicted best beams 215) associated with the performance monitoring instance 225 being within the subset of the beam set 210-b. Conversely, a performance monitoring instance 225 may be an ineligible performance monitoring instance 225 based on the best predicted best beam 215 of the one or more predicted best beams 215 associated with the performance monitoring instance 225 failing to be within (e.g., being outside of) the subset of the beam set 210-b. In such cases, the one or more cumulative performance metrics associated with the quantity of eligible performance monitoring instances 225 within the reporting window 230 may be indicative of one or more computed RSRP differences (e.g., statistics, such as mean or standards deviation, of computed L1-RSRP differences) . That is, the one or more computed RSRP differences may be based on (e.g., indicative of) a respective difference (e.g., for each eligible performance monitoring instance 225) between measured RSRP of the one or more (e.g., the at least N) respective predicted best beams 215 and measured RSRP of one or more corresponding actual beams 215 (e.g., associated with the same performance monitoring resources, of the subset of the beam set 210-b) . For example, the one or more computed RSRP differences may include an average computed RSRP difference (e.g., between predicted best beams 215 and corresponding actual beams 215) associated with the quantity of eligible performance monitoring instances 225.
[0113] In some cases (e.g., as described with reference to Option 1) , the UE 115-a may report an indication of the quantity of eligible performance monitoring instances 225 within the reporting window 230 (e.g., via a report 220 along with the one or more cumulative performance metrics) . In some cases, the UE 115-a may report an indication of the quantity of eligible performance monitoring instances 225 from among (e.g., out of) the plurality of performance monitoring instances 225. For example, continuing with the example depicted in FIG. 2, the UE 115-a may report an indication of a beam prediction accuracy (e.g., a cumulative performance metric) associated with the reporting window 230 and an indication that the beam prediction accuracy is based on 3 eligible performance monitoring instances 225 out of 4 total performance monitoring instances 225. Additionally, or alternatively, the UE 115-a may report an indication of a ratio of the quantity of eligible performance monitoring instances 225 relative to the plurality of performance monitoring instances 225. For example, continuing with the example depicted in FIG. 2, the UE 115-a may report an indication of a ratio of 0.75 (e.g., along with average L1-RSRP differences for eligible performance monitoring instances 225) . Additionally, or alternatively, the UE 115-a may report a bitmap indicative of the eligible performance monitoring instances 225. For example, continuing with the example depicted in FIG. 2, the UE 115-a may report a bitmap of 1110, where a value of 1 corresponds to an eligible performance monitoring instance 225 and a value of 0 corresponds to an ineligible performance monitoring instance 225.
[0114] Reporting an indication of the quantity of eligible performance monitoring instances 225 within the reporting window 230 may enable the network entity 105-a to evaluate a reliability of the one or more cumulative performance metrics. That is, if a cumulative performance metric is based on less than a threshold (e.g., a first threshold) quantity of eligible performance monitoring instances 225, the network entity 105-a may determine (e.g., identify) that the cumulative performance metric is not reliable and may increase a quantity of performance monitoring beams 215 in the subset of the beam set 210-b (e.g., to increase a likelihood of performance monitoring instances 225 being eligible) . In some examples, determination of the eligibility of a performance monitoring instance 225 may not be supported by the network entity 105-a (e.g., based on criteria for eligibility for a performance monitoring instance 225 being based on comparing prediction results to actual measurements) .
[0115] Additionally, or alternatively, (e.g., Option 2) , the UE 115-a may be configured with (e.g., may receive a control message indicative of) a threshold (e.g., a second threshold) quantity of eligible performance monitoring instances 225. In other words, the reporting window 230 may be based on the threshold quantity of eligible performance monitoring instances 225 (e.g., may not be fixed, may be a variable reporting window 230) . That is, the UE 115-a may count the quantity of eligible performance monitoring instances 225 (e.g., over time) and may transmit a report 220 when (e.g., based on) the quantity of eligible performance monitoring instances 225 satisfying (e.g., meeting or exceeding) the threshold quantity of eligible performance monitoring instances 225, where the report 220 is indicative of one or more cumulative performance metrics associated with the quantity of eligible performance monitoring instances 225 (e.g., associated with the threshold quantity of eligible performance monitoring instances 225) . In such cases, transmission of the report 220 based on the quantity of eligible performance monitoring instances 225 satisfying the threshold quantity of eligible performance monitoring instances 225 may implicitly indicate the quantity of eligible performance monitoring instances 225 to the network entity 105-a. Thus, because the network entity 105-a may be aware of a total quantity of performance monitoring instances 225 associated with the report 220 (e.g., based on a quantity of transmissions of the subset of the beam set 210-b) , the network entity 105-a may compare the quantity of eligible performance monitoring instances 225 to the total quantity of performance monitoring instances 225 to evaluate a performance of beam prediction by the UE 115-a (e.g., a performance of UE-side AI / ML models for beam prediction) . In such cases, determination of eligible performance monitoring instances 225 and reporting of the one or more cumulative performance metrics may be in accordance with techniques described herein (e.g., with reference to Option 1) .
[0116] In some cases, the UE 115-a may receive a control message indicative of whether the UE 115-a is to transmit a report 220 in accordance with the fixed reporting window 230 (e.g., Option 1) or in accordance with the threshold quantity of eligible performance monitoring instances 225 (e.g., Option 2) . In some cases, the control message may provide an explicit indication. That is, a first reporting mode may be associated with the fixed reporting window 230 and a second reporting mode may be associated with the threshold quantity of eligible performance monitoring instances 225, such that the control message may include an indication of either the first mode or the second mode. In some other cases, the control message may provide an implicit indication. That is, the control message may indicate to transmit the report 220 in accordance with the fixed reporting window 230 based on including an indication of the fixed reporting window 230. Conversely, the control message may indicate to transmit the report 220 in accordance with the threshold quantity of eligible performance monitoring instances 225 based on including an indication of the threshold quantity of eligible performance monitoring instances 225.
[0117] Reporting based on the fixed reporting window 230 (e.g., as described with reference to Option 1) versus reporting based on the threshold quantity of eligible performance monitoring instances 225 (e.g., as described with reference to Option 2) may provide different advantages. For example, reporting based on the threshold quantity of eligible performance monitoring instances 225 may support a reliability of one or more cumulative performance metrics (e.g., avoid a reliability issue) based on the one or more cumulative performance metrics being based on the threshold quantity of eligible performance monitoring instances 225. Conversely, in some cases, a duration associated with reaching the threshold quantity of eligible performance monitoring instances 225 may exceed a threshold duration (e.g., may be a long time) , such that the network entity 105-a may be unaware of a performance of the beam prediction by the UE 115-a (e.g., a performance of UE-side AI / ML models for beam prediction) during the duration.
[0118] Accordingly, in some cases (e.g., Option 3) , the UE 115-a may support reporting based on a combination (e.g., a hybrid) of the fixed reporting window 230 and the threshold quantity of eligible performance monitoring instances 225. For example, the UE 115-a may be configured with (e.g., may receive a control message indicating) the fixed reporting window 230 and the threshold quantity of eligible performance monitoring instances 225. In such cases, the UE 115-a may count the quantity of eligible performance monitoring instances 225 and if the quantity of eligible performance monitoring instances 225 fails to satisfy the threshold quantity of eligible performance monitoring instances 225 prior to expiration of the reporting window 230, the UE 115-a may compute one or more performance metrics based on the quantity of eligible performance monitoring instances 225 within the reporting window 230 and transmit a report 220 (e.g., based on expiration of the reporting window 230) indicative of the one or more performance metrics and indicative of the quantity of eligible performance monitoring instances 225 within the reporting window 230. In such cases, reporting of the quantity of eligible performance monitoring instances 225 within the reporting window 230 may be in accordance with techniques described herein (e.g., with reference to Option 1) .
[0119] In some cases, the UE 115-a may continue to count the quantity of eligible performance monitoring instances 225 after expiration of the reporting window 230 until the quantity of eligible performance monitoring instances 225 satisfies the threshold quantity of eligible performance monitoring instances 225. In such cases, the UE 115-a may compute one or more second performance metrics based on the quantity of eligible performance monitoring instances 225 (e.g., up to the point at which the quantity of eligible performance monitoring instances 225 satisfies the threshold quantity of eligible performance monitoring instances 225) and may transmit a second report 220 indicative of the one or more second performance metrics. In such cases, the one or more second performance metrics may be at least partially based on the one or more first performance metrics. That is, the one or more second performance metrics may be based on one or more (e.g., or no) eligible performance monitoring instances 225 within the reporting window 230 and based on one or more eligible performance monitoring instances 225 between expiration of the reporting window 230 and a time at which the quantity of eligible performance monitoring instances 225 satisfies the threshold quantity of eligible performance monitoring instances 225. In some other cases, the UE 115-a may reset the quantity of eligible performance monitoring instances 225 based on expiration of the reporting window 230. That is, the UE 115-a may start a second reporting window 230 and may restart counting of the quantity of eligible performance monitoring instances 225 (e.g., start counting of a second quantity of eligible performance monitoring instances) based on expiration of the reporting window 230 (e.g., until a new monitoring configuration is received from the network entity 105-a) .
[0120] Conversely, the UE 115-a may count the quantity of eligible performance monitoring instances 225 and if the quantity of eligible performance monitoring instances 225 satisfies the threshold quantity of eligible performance monitoring instances 225 prior to expiration of the reporting window 230, the UE 115-a may compute one or more performance metrics based on the quantity of eligible performance monitoring instances 225 (e.g., up to the point at which the quantity of eligible performance monitoring instances 225 satisfies the threshold quantity of eligible performance monitoring instances 225) and transmit a report 220 (e.g., prior to expiration of the reporting window 230) indicative of the one or more performance metrics. In such cases, reporting of the quantity of eligible performance monitoring instances 225 (e.g., equal to the threshold quantity of eligible performance monitoring instances 225) may be in accordance with techniques described herein (e.g., with reference to Option 1) .
[0121] Though described in the context of an eligible performance monitoring instance 225 being associated with (e.g., based on) at least a subset of one or more respective predicted best beams 215 (e.g., associated with the performance monitoring instance 225) being within a subset of the beam set 210-b, this is not to be regarded as a limitation of the present disclosure. In this regard, an eligible performance monitoring instance 225 is merely a performance monitoring instance 225 that would result in the UE 115-a reporting one or more per-instance performance metrics (e.g., transmission of a per-instance report 220 for the performance monitoring instance 225) for per-instance performance monitoring. Conversely, an ineligible performance monitoring instance 225 is merely a performance monitoring instance 225 that would not result in reporting of one or more per-instance performance metrics (e.g., transmission of a per-instance report 220 for the performance monitoring instance 225) for per-instance performance monitoring.
[0122] FIG. 3 shows an example of a process flow 300 that supports UE-initiated and event-driven performance monitoring reporting for limited performance monitoring sets in accordance with one or more aspects of the present disclosure. In some cases, the process flow 300 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, or both. For example, the process flow 300 may include one or more UEs 115 (e.g., a UE 115-b) and one or more network entities 105 (e.g., a network entity 105-b) , which may be examples of the corresponding devices as described herein. In the following description of the process flow 300, the operations between the UE 115-b and the network entity 105-b may be communicated in a different order than the example order shown, or the operations performed by the UE 115-b and the network entity 105-may be performed in different orders or at different times. Some operations may also be omitted from the process flow 300, and other operations may be added to the process flow 300.
[0123] In some cases, at 305, the UE 115-b may receive a control messages indicative of a reporting window, a threshold quantity of eligible performance monitoring instances, or both. In some examples, the one or more control messages may be indicative of whether the UE is to transmit a performance monitoring report in accordance with expiration of the reporting window, in accordance with a quantity of eligible performance monitoring instances (e.g., from multiple performance monitoring instances) satisfying the threshold quantity of eligible performance monitoring instances. For example, the control message may indicate that the UE 115-b is to transmit the performance monitoring report in accordance with expiration of the reporting window based on the control message including an indication of the reporting window (e.g., and not including an indication of the threshold quantity of eligible performance monitoring instances) . In another example, the control message may indicate that the UE 115-b is to transmit the performance monitoring report in accordance with the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances based on the control message including an indication of the threshold quantity of eligible performance monitoring instances (e.g., and not including an indication of the reporting window) . In another example, the control message may indicate that the UE 115-b is to transmit the performance monitoring report considering both the reporting window and the threshold quantity of eligible performance monitoring instances based on the control message including an indication of both the reporting window and the threshold quantity of eligible performance monitoring instances.
[0124] In some cases, the reporting window may include a fixed time duration (e.g., fixed time interval, fixed quantity of slots, fixed quantity of symbols) or a threshold quantity of performance monitoring instances. In such cases, the threshold quantity of performance instances may be based on one or more performance metrics (e.g., cumulative, window-based) to be included in the performance monitoring report.
[0125] At 310, the UE 115-b may receive multiple first reference signal sets via a first set of beams (e.g., Set B) , where each first reference signal set included in the multiple first reference signal sets is associated with one or more performance monitoring instances from among the multiple performance monitoring instances.
[0126] At 315, the UE 115-b may identify, for each performance monitoring instance of the multiple performance monitoring instances, one or more predicted best beams from among a second set of beams (e.g., Set A) in accordance with measurement of a respective first reference signal set of the plurality of first reference signal sets. In such cases, the one or more predicted best beams may be predicted to have highest signal qualities out of the second set of beams.
[0127] For example, for a first performance monitoring instance (e.g., of the multiple performance monitoring instances) , the UE 115-b may identify one or more first predicted best beams (e.g., from among the second set of beams) based on measurement of a respective first reference signal set (e.g., of the multiple first reference signal sets) associated with the first performance monitoring instance. Additionally, for a second performance monitoring instance (e.g., of the multiple performance monitoring instances) , the UE 115-b may identify one or more second predicted best beams (e.g., from among the second set of beams) based on measurement of a respective first reference signal set (e.g., of the multiple first reference signal sets) associated with the second performance monitoring instance.
[0128] At 320, the UE 115-b may receive multiple second reference signal sets via at least a subset of the second set of beams (e.g., a subset of Set A, performance monitoring beams) , where each second reference signal set, of the multiple second reference signal sets, may be associated with a respective performance monitoring instance from among the multiple performance monitoring instances. In some cases, the at least subset of the second set of beams may be the same for each performance monitoring instance or may be different for each performance monitoring instance (e.g., each performance monitoring instance may be associated with a respective subset of the second set of beams) .
[0129] For example, for the first performance monitoring instance (e.g., of the multiple performance monitoring instances) , the UE 115-b may receive a respective second reference signal set (e.g., of the multiple first reference signal sets) associated with the first performance monitoring instance. Additionally, for the second performance monitoring instance (e.g., of the multiple performance monitoring instances) , the UE 115-b may receive a respective second reference signal set (e.g., of the multiple first reference signal sets) associated with the second performance monitoring instance.
[0130] At 325, the UE 115-b may transmit a first performance monitoring report that is based on a quantity of eligible performance monitoring instances of the multiple performance monitoring instances. In such cases, an eligible performance monitoring instance may be associated with at least a threshold quantity of one or more respective predicted best beams being within the at least subset of the second set of beams. For example, the UE 115-a may predict one or more first predicted best beams for the first performance monitoring instance and may predict one or more second predicted best beams for the second performance monitoring instance. Thus, the UE 115-a may determine if the first performance monitoring instance is an eligible performance monitoring instance based on whether the one or more first predicted best beams are within the at least subset of the second set of beams and may determine if the second performance monitoring instance is an eligible performance monitoring instance based on whether the one or more second predicted best beams are within the at least subset of the second set of beams.
[0131] In some cases (e.g., the control message indicates the reporting window) , the multiple performance monitoring instances may be associated with the reporting window. In such cases, the performance monitoring report may indicate the quantity of eligible performance monitoring instances within the reporting window. That is, the performance monitoring report being based on the quantity of eligible performance monitoring instances may include the performance monitoring report indicating the quantity of eligible performance monitoring instances within the reporting window.
[0132] In some cases, the performance monitoring report may include an indication of the quantity of eligible performance monitoring instances from among (e.g., out of) the multiple performance monitoring instances (e.g., 4 of 5 performance monitoring instances are eligible) , an indication of a ratio of the quantity of eligible performance monitoring instances relative to the multiple performance monitoring instances (e.g., 0.8 performance monitoring instances are eligible) , a bitmap indicative of the eligible performance monitoring instances (e.g., 11110 indicating the first four performance monitoring instances are eligible and the last performance monitoring instance is ineligible) , or any combination thereof.
[0133] Additionally, or alternatively, (e.g., the control message indicates the threshold quantity of eligible performance monitoring instances) , the UE 115-b may transmit the first performance monitoring report based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances. In other words, the performance monitoring report being based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances.
[0134] Additionally, or alternative (e.g., the control message indicates both the reporting window and the threshold quantity of eligible performance monitoring instances) , the UE 115-b may transmit the first performance monitoring report based on an expiration of the reporting window or based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances. For example, in some cases, the UE 115-a may transmit, prior to expiration of the reporting window, the performance monitoring report based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances. In other words, the UE 115-a may transmit the performance monitoring report based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instance if the quantity of eligible performance monitoring instances satisfies the threshold quantity of eligible performance monitoring instance prior to expiration of the reporting window. In some other cases, the UE 115-b may transmit the performance monitoring report, despite the quantity of eligible performance monitoring instances failing to satisfy the threshold quantity of eligible performance monitoring instances, based at least in part on expiration of the reporting window. In other words, the UE 115-a may transmit the performance monitoring report based on expiration of the timer if the quantity of eligible performance monitoring instances fails to satisfy the threshold quantity of eligible performance monitoring instances within the reporting window. In such cases, the performance monitoring report may include the indication of the quantity of eligible performance monitoring instances from among the multiple performance monitoring instances, the indication of the ratio of the quantity of eligible performance monitoring instances relative to the multiple performance monitoring instances, the bitmap indicative of the eligible performance monitoring instances, or any combination thereof.
[0135] In any case, the performance monitoring report may be indicative of one or more respective performance metrics associated with each eligible performance monitoring instance included in the quantity of eligible performance monitoring instances. Conversely, the performance monitoring report may exclude one or more second respective performance metrics associated with each ineligible performance monitoring instance included in the multiple performance monitoring instances. In such cases, an ineligible performance monitoring instance may be associated with less than the threshold quantity of one or more respective predicted best beams being within the at least subset of the second set of beams.
[0136] In some cases, at 330, the UE 115-b may start a second reporting window based on transmission of the performance monitoring report (e.g., and based on expiration of the reporting window) .
[0137] In some other cases, at 335, the UE 115-b may transmit, after expiration of the reporting window, a second performance monitoring report based on the quantity of eligible performance monitoring instances satisfying the threshold quantity of eligible performance monitoring instances. That is, when the quantity of eligible performance monitoring instances fails to satisfy the threshold quantity of eligible performance monitoring instances within the reporting window, the UE 115-b may continue to count the quantity of eligible performance monitoring instances after expiration of the timer until the quantity of eligible performance monitoring instances satisfies the threshold quantity of eligible performance monitoring instances.
[0138] FIG. 4 shows a block diagram 400 of a device 405 that supports window-based metrics for predictive beam management for limited performance monitoring sets in accordance with one or more aspects of the present disclosure. The device 405 may be an example of aspects of a UE 115 as described herein. The device 405 may include a receiver 410, a transmitter 415, and a communications manager 420. The device 405, or one or more components of the device 405 (e.g., the receiver 410, the transmitter 415, the communications manager 420) , 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) .
[0139] The receiver 410 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 window-based metrics for predictive beam management for limited performance monitoring sets) . Information may be passed on to other components of the device 405. The receiver 410 may utilize a single antenna or a set of multiple antennas.
[0140] The transmitter 415 may provide a means for transmitting signals generated by other components of the device 405. For example, the transmitter 415 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 window-based metrics for predictive beam management for limited performance monitoring sets) . In some examples, the transmitter 415 may be co-located with a receiver 410 in a transceiver module. The transmitter 415 may utilize a single antenna or a set of multiple antennas.
[0141] The communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be examples of means for performing various aspects of window-based metrics for predictive beam management for limited performance monitoring sets as described herein. For example, the communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0142] In some examples, the communications manager 420, the receiver 410, the transmitter 415, 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) .
[0143] Additionally, or alternatively, the communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be implemented in code (e.g., as communications management software) 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 420, the receiver 410, the transmitter 415, 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) .
[0144] In some examples, the communications manager 420 may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 410, the transmitter 415, or both. For example, the communications manager 420 may receive information from the receiver 410, send information to the transmitter 415, or be integrated in combination with the receiver 410, the transmitter 415, or both to obtain information, output information, or perform various other operations as described herein.
[0145] The communications manager 420 may support wireless communications in accordance with examples as disclosed herein. For example, the communications manager 420 is capable of, configured to, or operable to support a means for receiving a set of multiple first reference signal sets via a first set of beams, where each first reference signal set included in the set of multiple first reference signal sets is associated with one or more respective performance monitoring instances from among a set of multiple performance monitoring instances. The communications manager 420 is capable of, configured to, or operable to support a means for identifying, for each performance monitoring instance of the set of multiple performance monitoring instances, one or more predicted best beams from among a second set of beams in accordance with measurement of a respective first reference signal set of the set of multiple first reference signal sets, where the one or more predicted best beams are predicted to have highest signal qualities out of the second set of beams. The communications manager 420 is capable of, configured to, or operable to support a means for receiving a set of multiple second reference signal sets via at least a subset of the second set of beams, where each second reference signal set, of the set of multiple second reference signal sets, is associated with a respective performance monitoring instance from among the set of multiple performance monitoring instances. The communications manager 420 is capable of, configured to, or operable to support a means for transmitting a performance monitoring report that is based on a quantity of eligible performance monitoring instances of the set of multiple performance monitoring instances, where an eligible performance monitoring instance is associated with at least a threshold quantity of one or more respective predicted best beams being within the at least subset of the second set of beams.
[0146] By including or configuring the communications manager 420 in accordance with examples as described herein, the device 405 (e.g., at least one processor controlling or otherwise coupled with the receiver 410, the transmitter 415, the communications manager 420, or a combination thereof) may support techniques for communication of a report associated with multiple performance monitoring instances based on a quantity of eligible performance monitoring instances among the multiple performance monitoring instances, which may result in reduced processing, reduced power consumption, more efficient utilization of communication resources, among other advantages.
[0147] FIG. 5 shows a block diagram 500 of a device 505 that supports window-based metrics for predictive beam management for limited performance monitoring sets in accordance with one or more aspects of the present disclosure. The device 505 may be an example of aspects of a device 405 or a UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communications manager 520. The device 505, or one or more components of the device 505 (e.g., the receiver 510, the transmitter 515, the communications manager 520) , may include at least one processor, which may be coupled with at least one memory, to support the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0148] The receiver 510 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 window-based metrics for predictive beam management for limited performance monitoring sets) . Information may be passed on to other components of the device 505. The receiver 510 may utilize a single antenna or a set of multiple antennas.
[0149] The transmitter 515 may provide a means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 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 window-based metrics for predictive beam management for limited performance monitoring sets) . In some examples, the transmitter 515 may be co-located with a receiver 510 in a transceiver module. The transmitter 515 may utilize a single antenna or a set of multiple antennas.
[0150] The device 505, or various components thereof, may be an example of means for performing various aspects of window-based metrics for predictive beam management for limited performance monitoring sets as described herein. For example, the communications manager 520 may include a monitoring component 525, a prediction component 530, a reporting component 535, or any combination thereof. The communications manager 520 may be an example of aspects of a communications manager 420 as described herein. In some examples, the communications manager 520, or various components thereof, may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 510, the transmitter 515, or both. For example, the communications manager 520 may receive information from the receiver 510, send information to the transmitter 515, or be integrated in combination with the receiver 510, the transmitter 515, or both to obtain information, output information, or perform various other operations as described herein.

The prediction component 530 is capable of, configured to, or operable to support a means for identifying, for each performance monitoring instance of the set of multiple performance monitoring instances, one or more predicted best beams from among a second set of beams in accordance with measurement of a respective first reference signal set of the set of multiple first reference signal sets, where the one or more predicted best beams are predicted to have highest signal qualities out of the second set of beams. The monitoring component 525 is capable of, configured to, or operable to support a means for receiving a set of multiple second reference signal sets via at least a subset of the second set of beams, where each second reference signal set, of the set of multiple second reference signal sets, is associated with a respective performance monitoring instance from among the set of multiple performance monitoring instances.

[0281] As used herein, including in the claims, “or” as used in a list of items (e.g., including a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means, e.g., A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ” As used herein, the term “and / or, ” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items can be employed. For example, if a composition is described as containing components A, B, and / or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
[0282] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0283] The term “determine” or “determining” or “identify” or “identifying” encompasses a variety of actions and, therefore, “determining” or “identifying” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure) , ascertaining and the like. Also, “determining” or “identifying” can include receiving (such as receiving information or signaling, e.g., receiving information or signaling for determining, receiving information or signaling for identifying) , accessing (such as accessing data in a memory , or accessing information) and the like. Also, “determining” or “identifying” can include resolving, obtaining, selecting, choosing, establishing and other such similar actions.
[0284] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
[0285] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0286] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure.
