[0042] Some wireless communications systems may support user equipment (UE) -assisted performance monitoring. In such cases, a network entity may transmit, to a UE for a single performance monitoring instance, multiple first reference signals via a first set of beams (e.g., Set B) . The UE may measure the first set of beams to generate a first set of actual measurements associated with the first set of beams and may input the first set of actual measurements into an artificial intelligence (AI) or machine learning (ML) model to generate a set of predicted measurements associated with a second set of beams (e.g., Set A) . The UE may then identify one or more predicted best beams (e.g., Top-K or Top-1 predicted best beams) from the set of second beams based on the set of predicted measurements (e.g., beams associated with a highest signal quality) . Additionally, the UE may receive, from the network entity for the single performance monitoring instance, multiple second reference signals via the second set of beams (e.g., Set A) and may measure the second set of beams to generate a second set of actual measurements associated with the second set of beams. Thus, the UE may compare one or more predicted measurements (e.g., from the set of predicted measurements) associated with the one or more predicted best beams from the second set of beams to one or more actual measurments (e.g., from the second set of actual measurements) associated with one or more actual best beams from the second set of beams and, in some cases, may report an indication of the comparison. However, in some cases, multiple performance monitoring instances, which may be referred to as a prediction set, may be associated with a same set of multiple first reference signals. That is, the first set of actual measurements input into the AI or ML model may be used to generate a respective set of predicted measurements associated with the second set of beams for each performance monitoring instance among the multiple performance monitoring instances. Additionally, in some cases, a performance monitoring window may include multiple prediction sets. In such cases, the UE may be unable to determine what metric or metrics to report to the network entity for the performance monitoring window.
[0043] Accordingly, techniques described herein may enable a UE to report one or more cumulative performance monitoring metrics for a performance monitoring window including multiple prediction sets. For example, the UE may receive, for each performance monitoring instance of multiple performance monitoring instances within a performance monitoring window, multiple first reference signal sets via a first set of beams (E. g., Set B) and may identify, for each performance monitoring instance within the performance monitoring window, one or more predicted best beams from a second set of beams in accordance with measurement of a respective first reference signal set. 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. The UE may additionally receive, for each performance monitoring instance, multiple second reference signal sets via at least a subset of the second set of beams and may transmit a performance monitoring report indicative of one or more cumulative performance monitoring metrics associated with the multiple performance monitoring instances within the performance monitoring window. The one or more cumulative performance monitoring metrics may be based on a quantity of successful performance monitoring instances within the performance monitoring window, where a successful performance monitoring instance is a performance monitoring instance in which one or more events occur based on one or more respective predicted best beams.
[0044] 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 beam prediction diagram and 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 performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances.
[0045] FIG. 1 shows an example of a wireless communications system 100 that supports performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances 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.
[0046] 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) .
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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) .
[0051] 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) ) .
[0052] 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.
[0053] 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.
[0054] 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 performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances 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) .
[0055] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0056] 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.
[0057] 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) .
[0058] 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.
[0059] 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) .
[0060] 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.
[0061] 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) ) .
[0062] 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) .
[0063] 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.
[0064] The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base stations 140) may have similar frame timings, and transmissions from different network entities (e.g., different ones of the network entities 105) may be approximately aligned in time.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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.
[0070] 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.
[0071] 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) .
[0072] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0073] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network entity 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entity 105 or UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0074] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0075] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0076] In some cases, the wireless communications system 100 may support techniques to enable a UE 115 to report one or more cumulative performance monitoring metrics for a performance monitoring window including multiple prediction sets. For example, the UE 115 may receive, for each performance monitoring instance of multiple performance monitoring instances within a performance monitoring window, multiple first reference signal sets via a first set of beams (E. g., Set B) and may identify, for each performance monitoring instance within the performance monitoring window, one or more predicted best beams from a second set of beams in accordance with measurement of a respective first reference signal set. 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. The UE 115 may additionally receive, for each performance monitoring instance, multiple second reference signal sets via at least a subset of the second set of beams and may transmit a performance monitoring report indicative of one or more cumulative performance monitoring metrics associated with the multiple performance monitoring instances within the performance monitoring window. The one or more cumulative performance monitoring metrics may be based on a quantity of successful performance monitoring instances within the performance monitoring window, where a successful performance monitoring instance is a performance monitoring instance in which one or more events occur based on one or more respective predicted best beams.
[0077] FIG. 2 shows an example of a wireless communications system 200 that supports performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances 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.
[0078] 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, a-periodically, 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.
[0079] 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, a-periodically, 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.
[0080] 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, a-periodically, 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.
[0081] In some cases, a UE 115, such as the UE 115-a, may perform performance monitoring for 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) . In some cases, as depicted in FIG. 2, the beam set 210-a may include wide beams 215. For each performance monitoring instance 225, the UE 115-a 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) . In some cases, as depicted in FIG. 2, 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) .
[0082] 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.
[0083] Thus, the UE 115-a may transmit a report 220 (e.g., one or more reports 220) indicating one or more per-instance performance monitoring 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 monitoring metrics (e.g., per-instance performance monitoring 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.
[0084] 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 set 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. 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, a subset of the beam set 210-b may be configured for performance monitoring.
[0085] Thus, in some cases, the UE 115-a may determine whether to transmit an indication of one or more per-instance performance monitoring 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 monitoring 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 monitoring metrics associated with the performance monitoring instance 225-a. In other words, the performance monitoring instance 225-a (e.g., as well as a performance monitoring instance 225-b and a performance monitoring instance 225-c) may be an eligible performance monitoring instance 225. Performance monitoring instances 225 may also inherently be eligible performance monitoring instances 225 when the network entity 105-a transmits all beams 215 of the beam set 210-b and the UE 115-a monitors for all beams 215 of the beam set 210-b. In other words, performance monitoring instances 225 may also inherently be eligible performance monitoring instances 225 when the performance monitoring beams 215 include all beams in the beam set 210-b.
[0086] Conversely, the UE 115-a may refrain from transmitting an indication of one or more per-instance performance monitoring 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 monitoring 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.
[0087] In some cases, the UE 115-a may determine (e.g., compute) 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 monitoring 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 monitoring metrics (e.g., window-based performance monitoring metrics) associated with the multiple performance monitoring instances 225 within a reporting window 230. In some cases, the one or more performance monitoring 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 monitoring metrics associated with each eligible performance monitoring instance 225 of multiple performance monitoring instances 225. Reporting of one or more cumulative performance monitoring 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) .
[0088] However, in some cases, as depicted in FIG. 3, measurement of the reference signals 205-a (e.g., during a measurement instance) may be associated with multiple performance monitoring instances 225 (e.g., multiple future prediction instances) . In such cases, the UE 115-a may perform temporal beam prediction with multiple performance monitoring instances 225 (e.g., future prediction instances) . That, rather than each performance monitoring instance 225 being associated with a respective set of reference signals 205-a, multiple performance monitoring instances 225 may be associated with a same set of reference signals 205-a. For example, for a set of performance monitoring instances 225 (e.g., within a prediction set) , the UE 115-a may receive, from the network entity 105-a, reference signals 205-a (e.g., a first set of reference signals 205) via the beam set 210-a (e.g., Set B) . The UE 115-a may measure the reference signals 205-a to generate a first set of actual measurements 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 the ML model at the UE 115-a to generate, for each performance monitoring instance 225 within the set of performance monitoring instances 225, a respective set of predicted measurements associated with the beam set 210-b (e.g., each beam 215 in the beam set 210-b) . For each performance monitoring instance 225 (e.g., within the set of performance monitoring instances 225) , the UE 115-a may then predict one or more respective predicted best beams 215 from the beam set 210-b based on the respective set of predicted measurements.
[0089] For example, the UE 115-a may generate, based on the first set of actual measurements, a first set of predicted measurements associated with a first performance monitoring instances 225 (e.g., and associated with the beam set 210-b) and a second set of predicted measurements associated with a second performance monitoring instances 225 (e.g., and associated with the beam set 210-b) . Additionally, the UE 115-a may predict one or more first predicted best beams 215 from the beam set 210-b for the first performance monitoring instances 225 based on the first set of predicted measurements and may predict one or more second predicted best beams 215 from the beam set 210-b for the second performance monitoring instances 225 based on the second set of predicted measurements.
[0090] Additionally, for each performance monitoring set 225 (e.g., within the set of performance monitoring instances 225) , the UE 115-a may receive, from the network entity 105-a, respective reference signals 205-b via the beam set 210-b (e.g., via at least a subset of the beam set 210-b) and may measure the respective reference signals 205-b to generate a respective second set of actual measurements associated with the beam set 210-b. For example, the UE 115-a may receive first reference signals 205-b via the beam set 210-b (e.g., via at least the subset of the beam set 210-b) for the first performance monitoring instance 225 and may receive second reference signals 205-b via the beam set 210-b (e.g., via at least the subset of the beam set 210-b) for the second performance monitoring instance 225. Thus, the UE 115-a may generate a respective second set of actual measurements associated with the beam set 210-b for each of the first performance monitoring instance 225 and the second first performance monitoring instance 225 based on measurement of the first reference signals 205-b and the second reference signals 205-b, respectively.
[0091] However, the one or more performance monitoring metrics (e.g., window-based performance monitoring metrics) generated for temporal beam prediction with a single performance monitoring instance 225 (e.g., each performance monitoring instance 225 is associated with respective reference signals 205-a) , as depicted in FIG. 2 and described herein, may not accurately reflect temporal beam prediction performance for temporal beam prediction with multiple performance monitoring instances 225, as depicted in FIG. 3 (e.g., due to all performance monitoring instances 225 being reported with equal priority for temporal beam prediction with a single performance monitoring instance 225) .
[0092] Accordingly, techniques described herein may support generation of one or more performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances within a performance monitoring window, as described further with reference to FIG. 3. For example, the UE 115-a may receive reference signals 205-a via the beam set 210-a and may identify, for each performance monitoring instance 225 within the performance monitoring window, one or more respective predicted best beams 215 from the beam set 210-b in accordance with measurement of the reference signals 205-a. The UE 115-a may additionally receive, for each performance monitoring instance 225 within the performance monitoring window, respective reference signals 205-b via at least a subset of the beam set 210-b and may transmit a report 220 indicative of one or more cumulative performance monitoring metrics associated with the set of performance monitoring instances 225 within the performance monitoring window. In such cases, the one or more cumulative performance monitoring metrics may be based on a quantity of successful performance monitoring instances 225 within the performance monitoring window, where a successful performance monitoring instance 225 is a performance monitoring instance 225 in which one or more events occur based at least in part on the one or more respective predicted best beams 215.
[0093] FIG. 3 shows an example of a beam prediction diagram 300 that supports performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances in accordance with one or more aspects of the present disclosure. In some cases, the beam prediction diagram 300 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, or both. For example, the beam prediction diagram 300 may be implemented by one or more UEs 115 and one or more network entities 105, which may be examples of the corresponding devices as described herein.
[0094] As described with reference to FIG. 2, in some cases, a UE 115 may perform temporal beam prediction for multiple performance monitoring instances, which may also be referred to as prediction instances 310 (e.g., future prediction instances 310) . For example, the UE 115 may receive, from a network entity 105, a set of first reference signals via a beam set 330-a (e.g., Set B) , associated with (e.g., during) a measurement instance 305-a. In such cases, the measurement instance 305-a may be associated with a prediction set 320-a including multiple (e.g., a set of) prediction instances 310 (e.g., performance monitoring instances) , such that measurement of the set of first reference signals associated with the measurement instance 305-a may be used to generate respective predictions for each prediction instance 310 within the prediction set 320-a.
[0095] For example, the UE 115 may measure the set of first reference signals received via the beam set 330-a to generate a set of actual measurements (e.g., a set of first actual measurements) associated with the beam set 330-a (e.g., each beam in the beam set 330-a) and may input the set of actual measurements associated with the beam set 330-a into an ML model at the UE 115 to generate, for each prediction instance 310 in the prediction set 320-a, a respective set of predicted measurements associated with a beam set 330-b (e.g., each beam in the beam set 330-b) . That is, the UE 115 may generate, based on the set of actual measurements associated with the beam set 330-a, a first set of predicted measurements associated with the beam set 330-b for (e.g., associated with) a prediction instance 310-a, a second set of predicted measurements associated with the beam set 330-b for a prediction instance 310-b, a third set of predicted measurements associated with the beam set 330-b for a prediction instance 310-c, and a fourth set of predicted measurements associated with the beam set 330-b for a prediction instance 310-d.
[0096] Additionally, the UE 115 may predict, for each prediction instance 310 (e.g., within the prediction set 320-a) , one or more respective predicted best beams from the beam set 330-b based on a respective set of predicted measurements. For example, the UE 115 may predict one or more first predicted best beams for (e.g., associated with) the prediction instance 310-a based on the first set of predicted measurements, one or more second predicted best beams for the prediction instance 310-b based on the second set of predicted measurements, one or more third predicted best beams for the prediction instance 310-c based on the third set of predicted measurements, and one or more fourth predicted best beams for the prediction instance 310-d based on the fourth set of predicted measurements.
[0097] Additionally, for each prediction instance 310 (e.g., within the prediction set 320-a) , the UE 115 may receive a respective set of second reference signals via at least a subset of the beam set 330-b and may measure the respective set of second reference signals to generate a respective set of actual measurements (e.g., a respective set of second actual measurements) associated with the beam set 330-b. Though FIG. 3 depicts and describes that the UE 115 receives the respective set of second reference signals via all of the beam set 330-b, this is not to be regarded as a limitation of the present disclosure, such that, as described with reference to FIG. 2, the UE 115 may receive the respective set of second reference signals via the subset of the beam set 330-b.
[0098] For example, the UE 115 may receive a first set of second reference signals via the beam set 330-b for the prediction instance 310-a, a second set of second reference signals via the beam set 330-a for the prediction instance 310-b, a third set of second reference signals via the beam set 330-a for the prediction instance 310-c, and a fourth set of second reference signals via the beam set 330-a for the prediction instance 310-d. Thus, the UE 115 may generate, for the prediction instance 310-a, a first set of actual measurements associated with the beam set 330-b based on measurement of the first set of second reference signals, may generate, for the prediction instance 310-b, a second set of actual measurements associated with the beam set 330-b based on measurement of the second set of second reference signals, may generate, for the prediction instance 310-c, a third set of actual measurements associated with the beam set 330-b based on measurement of the third set of second reference signals, and may generate, for the prediction instance 310-d, a fourth set of actual measurements associated with the beam set 330-b based on measurement of the fourth set of second reference signals.
[0099] In some cases, the UE 115 may identify, for each prediction instance 310 (e.g., within the prediction set 320-a) , one or more actual best beams from the beam set 330-b (e.g., from at least the subset of the beam set 330-b) based on a respective set of actual measurements associated with the beam set 330-b. For example, the UE 115 may identify, for the prediction instance 310-a, one or more first actual best beams from the beam set 330-b based on the first set of actual measurements associated with the beam set 330-b, may identify, for the prediction instance 310-b, one or more second actual best beams from the beam set 330-b based on the second set of actual measurements associated with the beam set 330-b, may identify, for the prediction instance 310-c, one or more third actual best beams from the beam set 330-b based on the third set of actual measurements associated with the beam set 330-b, and may identify, for the prediction instance 310-d, one or more fourth actual best beams from the beam set 330-b based on the fourth set of actual measurements associated with the beam set 330-b.
[0100] In some cases, as depicted in FIG. 3, the UE 115 may repeat the process described herein for multiple prediction sets 320 within a monitoring window 315, such as a prediction set 320-b associated with a measurement instance 305-b, where the prediction set 320-b includes a prediction instance 310-e, a prediction instance 310-f, a prediction instance 310-g, and a prediction instance 310-h. In some cases, predictions for prediction instances 310 in the prediction set 320-b (e.g., at t1, t2, t3, t4, and t5) may be based on an actual measurements associated with the beam set 330-a measured during the measurement instance 305-b (e.g., at t0) , as well as the actual measurements associated with the beam set 330-a measured during the measurement instance 305-a (e.g., at t-5) .
[0101] Thus, the UE 115 may transmit a performance monitoring report, which may simply be referred to as the report, indicating one or more cumulative, or window-based, performance monitoring metrics associated with the monitoring window 315 (e.g., performance monitoring window) . That is, the one or more cumulative performance monitoring metrics may be based on at least a subset of the prediction instances 310 in the monitoring window 315, such as the prediction instance 310-a, the prediction instance 310-b, the prediction instance 310-c, the prediction instance 310-d, the prediction instance 310-e, the prediction instance 310-f, the prediction instance 310-g, and the prediction instance 310-h.
[0102] In some cases (e.g., when all prediction instances 310 within the monitoring window 315 are treated equally) , the one or more cumulative performance monitoring metrics may be based on a quantity occurrences of one or more events within the monitoring window 315. For example, the one or more cumulative performance monitoring metrics may include a first (e.g., a single first) cumulative performance monitoring metric that is based on the quantity of occurrences of the one or more events within the monitoring window 315. In some example, the first cumulative performance monitoring metric may explicitly indicate the quantity occurrences of the one or more events within the monitoring window 315. Additionally, or alternatively, the first cumulative performance monitoring metric may indicate the quantity occurrences of the one or more events within the monitoring window 315 divided by (e.g., relative to) a total quantity of prediction instances 310 within the monitoring window 315. In some cases, the total quantity of prediction instances 310 within the monitoring window 315 may include all prediction instances 310 within the monitoring window 315 (e.g., eligible prediction instances 310 and ineligible prediction instances 310) . In some other cases, the total quantity of prediction instances 310 within the monitoring window 315 may include eligible prediction instances 310 (e.g., and not ineligible prediction instances 310) within the monitoring window 315
[0103] As described with reference to FIG. 2, when the UE 115 receives the respective sets of second reference signals via the subset of the beam set 330-a, an eligible prediction instance 310 (e.g., eligible performance monitoring instance) may be a prediction instance 310 in which at least a subset of one or more respective predicted best beams (e.g., associated with the prediction instance 310) are within the subset of the subset of the beam set 330-a. Thus, when the UE 115 receives the respective sets of second reference signals via all of the beam set 330-a, all prediction instances 310 may inherently be eligible prediction instances 310 such that the total quantity of eligible prediction instances 310 within the monitoring window 315 includes all prediction instances 310 within the monitoring window 315.
[0104] In such cases, the one or more events may be associated with (e.g., based on) the prediction instances 310 within the monitoring window 315. That is, the UE 115-a may evaluate each prediction instance 310 for an occurrence of the one or more events and, if at least one of the one or more events occurs, then the prediction instance 310 may be considered a successful prediction instance 310 and may be counted in the quantity occurrences of the one or more events. In other words, the quantity occurrences of the one or more events within the monitoring window 315 may be synonymous to a quantity of successful prediction instances 310 within the monitoring window 315.
[0105] In some cases, such as when the UE 115 receives the respective sets of second reference signals via the subset of the beam set 330-a, the one or more events may include a first event (e.g., Event A) . The first event may occur when one or more (e.g., Top-K) predicted best beams associated with a prediction instance 310 are within the subset of the beam set 330-a. In other words, a prediction instance 310 may be a successful prediction instance 310 when the one or more (e.g., Top-K) predicted best beams associated with the prediction instance 310 are within the subset of the beam set 330-a (e.g., a successful prediction instance 310 is an eligible prediction instance 310) . Additionally, or alternatively, the one or more events may include one or more events associated with beam prediction accuracy. For example, a second event (e.g., Event-1) may occur when a Top-1 actual best beam (e.g., Top-1 measured best beam within the beam set 330-a, actual best beam with a highest RSRP) associated with a prediction instance 310 is within (e.g., among) one or more (e.g., Top-K) predicted best beams associated with the prediction instance 310. In other words, a prediction instance 310 may be a successful prediction instance 310 when the Top-1 actual best beam (e.g., from the beam set 330-b) associated with the prediction instance 310 is within the one or more (e.g., Top-K) predicted best beams associated with the prediction instance 310. Additionally, or alternatively, the second event (e.g., Event-1b) may occur when at least one of a Top-M actual best beam (e.g., Top-M measured best beam within the beam set 330-a, Top-M actual best beams with highest RSRPs within the beam set 330-a) associated with the prediction instance 310 is within the one or more (e.g., Top-K) predicted best beams associated with the prediction instance 310 (e.g., where K>M) .
[0106] Additionally, or alternatively, a third event (e.g., Event-2) may occur when a Top-1 predicted best beam (e.g., a predicted best beam with a highest RSRP from among the one or more predicted best beams) associated with a prediction instance 310 is within (e.g., among) one or more (e.g., Top-K) actual best beams associated with the prediction instance 310. In other words, a prediction instance 310 may be a successful prediction instance 310 when the Top-1 predicted best beam associated with the prediction instance 310 is within one or more (e.g., Top-K) actual best beams associated with the prediction instance 310. Additionally, or alternatively, the third event (e.g., Event-2b) may occur when at least one of the one or more (e.g., Top-K) predicted best beams are within one or more (e.g., Top-M) actual best beams associated with the prediction instance 310 (e.g., associated with M highest RSRPs within the beam set 330-a) .
[0107] Additionally, or alternatively, the one or more events may include one or more events associated with a difference between actual (e.g., measured) measurments, which may be RSRP (e.g., L1-RSRPs) . For example, a fourth event (e.g., Event-3) may occur when an actual RSRP of the Top-1 predicted best beam associated with a prediction instance 310 is within a first threshold deviation (e.g., X3 dBs) of an actual RSRP of the Top-1 actual best beam (e.g., from the beam set 330-b) associated with the prediction instance 310. In other words, a prediction instance 310 may be a successful prediction instance 310 when the the actual RSRP of the Top-1 predicted best beam associated with the prediction instance 310 is within the first threshold deviation of the actual RSRP of the Top-1 actual best beam associated with the prediction instance 310. Additionally, or alternatively, the fourth event (e.g., Event-3b) may occur when the actual RSRP of the Top-1 predicted best beam associated with the prediction instance 310 is within the first threshold deviation of the actual RSRP of the Top-1 actual best beam associated with the prediction instance 310 and the Top-1 predicted best beam is within the subset of the beam set 330-a (e.g., the performance monitoring set) .
[0108] Additionally, or alternatively, a fifth event (e.g., Event-4) may occur when a highest (e.g., greatest) actual RSRP of the one or more (e.g., Top-K) predicted best beams associated with a prediction instance 310 is within a second threshold duration (e.g., X4 dBs) of the actual RSRP of the Top-1 actual best beam (e.g., from the beam set 330-b) associated with the prediction instance 310. In other words, a prediction instance 310 may be a successful prediction instance 310 when the highest actual RSRP associated with the one or more (e.g., Top-K) predicted best beams is within the second threshold duration (e.g., X4 dBs) of the actual RSRP of the Top-1 actual best beam associated with the prediction instance 310. In some cases (e.g., Event-4b) , the one or more (e.g., Top-K) predicted best beams may be the one or more (e.g., Top-K) predicted best beams that are within the subset of the beam set 330-a (e.g., the performance monitoring set) .
[0109] Additionally, or alternatively, the one or more events may include one or more events associated with a difference between actual RSRPs and predicted RSRPs. For example, a sixth event may occur when a predicted RSRP of the Top-1 predicted best beam associated with a prediction instance 310 is within a third threshold deviation (e.g., X5 dBs) of an actual RSRP of the Top-1 predicted best beam associated with the prediction instance 310. In other words, a prediction instance 310 may be a successful prediction instance 310 when the predicted RSRP of the Top-1 predicted best beam associated with the prediction instance 310 is within the third threshold deviation (e.g., X5 dBs) of the actual RSRP of the Top-1 predicted best beam associated with the prediction instance 310. Additionally, or alternatively, the sixth event (e.g., Event-5b) may occur when the predicted RSRP of the Top-1 predicted best beam associated with the prediction instance 310 is within the third threshold deviation of the actual RSRP of the Top-1 predicted best beam associated with the prediction instance 310 and the Top-1 predicted best beam is within the subset of the beam set 330-a (e.g., the performance monitoring set) .
[0110] Additionally, or alternatively, a seventh event (e.g., Event-6) may occur when a highest predicted RSRP of the one or more (e.g., Top-K) predicted best beams associated with a prediction instance 310 is within a fourth threshold deviation (e.g., X6 dBs) of an actual RSRP of a same beam (e.g., a beam having the highest predicted RSRP of the Top-K predicted best beams) . In some cases (e.g., Event-6b) , the one or more (e.g., Top-K) predicted best beams may be the one or more (e.g., Top-K) predicted best beams that are within the subset of the beam set 330-a (e.g., the performance monitoring set) .
[0111] In some cases, the network entity 105 may configure (e.g., may transmit control signaling to the UE 115 indicating) the first threshold, the second threshold, the third threshold, the fourth threshold, a quantity of the one or more predicted best beams (e.g., a value of K) , a value of M, or any combination thereof. Additionally, or alternatively, the first threshold, the second threshold, the third threshold, the fourth threshold, or any combination thereof, may be a function of an actual RSRP of the Top-1 actual best beam (e.g., from the beam set 330-b) . Additionally, or alternatively, an event may be defined by a combination of any of the first event, the second event, the third event, the fourth event, the fifth event, the sixth event, and the seventh event. For example, an eighth event may occur when both the first event and the second event occurs for a same prediction instance 310.
[0112] Thus, as described previously, the one or more cumulative performance monitoring instance may include the first cumulative performance monitoring metric that is based on the quantity of successful prediction instances 310 within the monitoring window 315, Np. As discussed previously, in some cases, the first cumulative performance monitoring metric may indicate the quantity of successful prediction instances 310 within the monitoring window 315, Np. Additionally, or alternatively, the first cumulative performance monitoring metric may indicate the quantity of successful prediction instances 310 within the monitoring window 315, Np, divided by the quantity of eligible prediction instances 310 within the monitoring window 315, N. In other words, the first cumulative performance monitoring instance may be For example, in the context of FIG. 3, the UE 115 may receive the respective sets of second reference signals via all of the beam set 330-a, such that all prediction instances 310 within the monitoring window 315 are eligible prediction instances 310. Additionally, the UE 115 may determine that the prediction instance 310-a, the prediction instance 310-b, the prediction instance 310-c, the prediction instance 310-e, the prediction instance 310-g, and the prediction instance 310-h are successful prediction instances 310, such that the UE 115 may transmit, to the network entity 105, a performance monitoring report associated with the monitoring window 315 indicating 6 / 8 as the first cumulative performance monitoring metric.
[0113] Additionally, or alternatively, the one or more cumulative performance monitoring metrics may include a second (e.g., a single second) cumulative performance monitoring metric that is based on a respective per-instance performance monitoring metric for each prediction instance 310 (e.g., eligible prediction instance) within the monitoring window 315. That is, the UE 115 may calculate, or otherwise determine, a per-instance performance monitoring metric for each prediction instance 310 within the monitoring window 315 and may divide a sum of the per-instance performance monitoring metrics for the prediction instances 310 within the monitoring window 315 by a total quantity of the prediction instances 310 within the monitoring window 315. In some cases, the UE 115 may calculate a per-instance performance monitoring metric for each eligible prediction instance 310 within the monitoring window 315. In such cases, the total quantity of the prediction instances 310 within the monitoring window 315 may include a total quantity of eligible prediction instances 310 within the monitoring window 315. In some other cases, the UE 115 may calculate a per-instance performance monitoring metric for each prediction instance 310 within the monitoring window 315, regardless of whether a prediction instance 310 is eligible or ineligible. In such cases, the total quantity of the prediction instances 310 within the monitoring window 315 may include all prediction instances 310 within the monitoring window 315 (e.g., eligible prediction instances 310 and ineligible prediction instances 310) .
[0114] As described previously, when the UE 115 receives the respective sets of second reference signals via all of the beam set 330-a, all prediction instances 310 may inherently be eligible prediction instances 310 such that the total quantity of eligible prediction instances 310 within the monitoring window 315 includes all prediction instances 310 within the monitoring window 315.
[0115] For example, the per-instance performance monitoring metric may be Δi, which may be defined as an RSRP difference between a measured RSRP of the Top-1 predicted best beam (e.g., associated with a beam ID the Top-1 predicted best beam) associated with a prediction instance 310 and a measured RSRP of a Top-1 actual best beam associated with the prediction instance 310. Thus, the second cumulative performance monitoring metric may be equal to where N may be the total quantity of eligible prediction instances 310 within the monitoring window 315. In another example, the per-instance performance monitoring metric may be Γi, which may be defined as an absolute value of a difference between a measured RSRP and a predicted RSRP for the Top-1 predicted best beam associated with a prediction instance 310. Thus, the second cumulative performance monitoring metric may be equal to where N may be the total quantity of eligible prediction instances 310 within the monitoring window 315.
[0116] Additionally, or alternatively, the prediction instances 310 within the monitoring window 315 may be divided into multiple groups of prediction instances 310 (e.g., not to be confused with prediction sets 320) such that a performance monitoring report associated with the monitoring window 315 (e.g., transmitted by the UE 115) may include one or more cumulative respective (e.g., separate) performance monitoring metrics per group of prediction instances 310. For example, as described previously, each prediction set 320 may include multiple prediction instances 310, and the multiple prediction instances 310 may be sequentially ordered in a time domain. That is, for the prediction set 320-a, the prediction instance 310-a may be a first prediction instance 310 within the prediction set 320-a, the prediction instance 310-b may be a second prediction instance 310 within the prediction set 320-a, the prediction instance 310-c may be a third prediction instance 310 within the prediction set 320-a, and the prediction instance 310-d may be a fourth prediction instance 310 within the prediction set 320-a. Similarly, for the prediction set 320-b, the prediction instance 310-e may be a first prediction instance 310 within the prediction set 320-b, the prediction instance 310-f may be a second prediction instance 310 within the prediction set 320-b, the prediction instance 310-g may be a third prediction instance 310 within the prediction set 320-b, and the prediction instance 310-h may be a fourth prediction instance 310 within the prediction set 320-a. Thus, the UE 115 may group first prediction instances 310 (e.g., the prediction instance 310-a and the prediction instance 310-e) into a first group of prediction instances, second prediction instances 310 (e.g., the prediction instance 310-b and the prediction instance 310-f) into a second group of prediction instances, third prediction instances 310 (e.g., the prediction instance 310-c and the prediction instance 310-g) into a third group of prediction instances, and fourth prediction instances 310 (e.g., the prediction instance 310-d and the prediction instance 310-h) into a fourth group of prediction instances.
[0117] In some cases, the UE 115 may generate (e.g., calculate) and report the first performance monitoring metric for each group of prediction instances 310. Continuing with the example in FIG. 3, the UE 115 may report four performance monitoring metrics including the first cumulative performance monitoring metric associated with the first group of prediction instances 310, the first cumulative performance monitoring metric associated with the second group of prediction instances 310, the first cumulative performance monitoring metric associated with the third group of prediction instances 310, and the first cumulative performance monitoring metric associated with the fourth group of prediction instances 310.
[0118] Additionally, or alternatively, the UE 115 may generate and report the second performance monitoring metric for each group of prediction instances 310. Continuing with the example in FIG. 3, the UE 115 may report four performance monitoring metrics including the second cumulative performance monitoring metric associated with the first group of prediction instances 310, the second cumulative performance monitoring metric associated with the second group of prediction instances 310, the second cumulative performance monitoring metric associated with the third group of prediction instances 310, and the second cumulative performance monitoring metric associated with the fourth group of prediction instances 310.
[0119] As described herein, in some cases, the per-instance performance monitoring metric used to calculate the second performance monitoring metric may be Δi. Thus, the second cumulative performance monitoring metric for each group of prediction instances 310 may be equal to where m may be the total quantity of eligible prediction instances 310 within a given group of prediction instances 310.
[0120] Reporting the one or more cumulative performance monitoring metrics per group of prediction instances 310 may enable the UE 115 to report more granular information about performance of temporal beam prediction as a function of how far into the future the UE 115 is predicting (e.g., as compared to not grouping the prediction instances 310) . In other words, within each prediction set 320, the prediction instances 310 are varying durations 325 from a measurement instance 305 used in generation of the respective predictions (e.g., for the prediction instances) , such that reporting of the one or more cumulative performance monitoring metrics per group of prediction instances 310 may enable the UE 115 to identifying differences in reliability of predictions due to different durations 325 from the measurement instance 305.
[0121] For example, as discussed previously, for the prediction set 320-a, the prediction instance 310-a may be the first prediction instance 310 within the prediction set 320-a based on the prediction instance 310-a being a duration 325-a from the measurement instance 305-a, the prediction instance 310-b may be the second prediction instance 310 within the prediction set 320-a based on the prediction instance 310-b being a duration 325-b from the measurement instance 305-a, the prediction instance 310-c may be the third prediction instance 310 within the prediction set 320-a based on the prediction instance 310-c being a duration 325-c from the measurement instance 305-a, and the prediction instance 310-d may be the fourth prediction instance 310 within the prediction set 320-a based on the prediction instance 310-d being a duration 325-d from the measurement instance 305-a. In such cased, the duration 325-a may be less than the duration 325-b, which may be less than the duration 325-c, which may be less than the duration 325-d. Thus, in some cases, the UE 115 may identify that one or more performance monitoring metrics associated with a group of fourth prediction instances 310 (e.g., including at least the prediction instance 310-d) may indicate a lower prediction accuracy than one or more performance monitoring metrics associated with a group of first prediction instances 310 (e.g., including at least the prediction instance 310-a) , which may further indicate that the closer a prediction instance 310 is to a respective measurement instance 305, the more accurate the prediction.
[0122] Additionally, or alternatively, the UE 115 may generate one or more respective set-based performance monitoring metrics (e.g., Mi) per prediction set 320, and may generate the one or more cumulative performance monitoring metrics based on the one or more respective set-based performance monitoring metrics per prediction set 320. For example, for the prediction set 320-a, the UE 115 may generate a first per-instance performance monitoring metric associated with the prediction instance 310-a, Δ1, a second per-instance performance monitoring metric associated with the prediction instance 310-b, Δ2, a third per-instance performance monitoring metric associated with the prediction instance 310-c, Δ3, and a fourth per-instance performance monitoring metric associated with the prediction instance 310-d, Δ4. Though described in the context of Δi (e.g., RSRP delta, as described herein) , this is not to be intended as a limitation of the present disclosure, such that any per-instance performance monitoring metric may be considered with regards to the techniques described herein.
[0123] Additionally, the UE 115 may apply a set of weights (e.g., importance weights) to the respective per-instance performance monitoring metrics based on a respective duration 325 from (e.g., temporal closeness to) the measurement instance 305-a. For example, the UE 115 may apply a first weight, w1, to the first per-instance performance monitoring metric based on the prediction instance 310-a being the duration 325-a from the measurement instance 305-a, a second weight, w2, to the second per-instance performance monitoring metric based on the prediction instance 310-b being the duration 325-b from the measurement instance 305-a, a third weight, w3, to the third per-instance performance monitoring metric based on the prediction instance 310-c being the duration 325-c from the measurement instance 305-a, and a fourth weight, w4, to the fourth per-instance performance monitoring metric based on the prediction instance 310-d being the duration 325-d from the measurement instance 305-a. In such cases, the first weight may be greater than the second weight, which may be greater than the third weight, which may be greater than the fourth weight, (e.g., w1>w2>w3>w4) based on the the duration 325-a being less than the duration 325-b, being less than the duration 325-c, being less than the duration 325-d. In some examples, a per-instance performance monitoring metric associated with an ineligible prediction instance 310 may be weighted with a weight equal to 0.
[0124] Thus, the UE 115 may generate a set-based performance monitoring metric, M1, for the prediction set 320-a according to The UE 115 may generate a respective set-based performance monitoring metric for each prediction set 320 within a monitoring window 315 (e.g., based on respective per-instance performance monitoring metrics associated with respective prediction instances 310) and may generate a third cumulative performance monitoring metric (e.g., of the one or more performance monitoring metrics) based on averaging the respective set-based performance monitoring metrics. In other words, for the monitoring window 315, the prediction set 320-a may be associated with a first set-based performance monitoring metric, M1, and the prediction set 320-b may be associated with a second set-based performance monitoring metric, M2, such that the third cumulative performance monitoring metric is equal to If an additional prediction set 320 associated with a third set-based performance monitoring metric, M3, were within the monitoring window 315, then the third cumulative performance monitoring metric would be equal to
[0125] Additionally, or alternatively, the per-instance performance monitoring metrics may be weighted (e.g., averaged) via an exponentially weighted moving average. For example, for the prediction set 320-a, the UE 115 may generate a fourth set-based performance monitoring metric, M′i, in accordance with M′i=αΔi+ (1-α) M′i-1, where α may be a smoothing factor (e.g., 0<α<1) . In some cases, the network entity may configure the UE 115 (e.g., transmit control signaling indicative of) with the set of weights, the smoothing factor, or both.
[0126] Though described in the context of RSRP, this is not to be regarded as a limitation of the present disclosure. In this regard, other measurements may be considered with regards to the techniques described herein. Further, though depicted in the context of two prediction sets 320 within the monitoring window 315, each associated with four prediction instances 310, this is not to be regarded as a limitation of the present disclosure. In this regard, the monitoring window 315 may include any quantity of predictions sets 320, and each prediction set may include any quantity of prediction instances 310 (e.g., two or more prediction instances 310) .
[0127] FIG. 4 shows an example of a process flow 400 that supports performance monitoring metrics for temporal beam prediction with multiple performance monitoring instances in accordance with one or more aspects of the present disclosure. In some cases, the process flow 400 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the beam prediction diagram 300, or any combination thereof. For example, the process flow 400 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-a) , which may be examples of the corresponding devices as described herein. In the following description of the process flow 400, 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 400, and other operations may be added to the process flow 400.
[0128] At 405, the UE 115-b may receive, from the network entity 105-b (e.g., during a measurement instance) , 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 respective performance monitoring instances (e.g., prediction instances_from among multiple performance monitoring instances within a performance monitoring window.
[0129] At 410, the UE 115-b may identify, for each performance monitoring instance within the performance monitoring window, 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 (e.g., a corresponding first reference signal set) of the multiple first reference signal sets. In such cases, the one or more predicted best beams may be predicted to have highest signal qualities (e.g., RSRPs) out of the second set of beams.
[0130] At 415, the UE 115-b may receive, from the network entity 105-b, multiple second reference signal sets via at least a subset of the second set of beams, where each second reference signal set, of the multiple second reference signal sets, is associated with a respective performance monitoring instance within the performance monitoring window.
[0131] In some cases, at 420, the UE 115-b may identify a per-instance performance monitoring metric associated with each performance monitoring instance of the plurality of performance monitoring instances.
[0132] In some cases, at 425, the UE 115-b may calculate one or more fourth cumulative performance monitoring metrics based on weighing each of the per-instance performance monitoring metrics. In such cases, per-instance performance monitoring metrics associated with successful performance monitoring instances may be weighted in accordance with a respective non-zero weight, and per-instance performance monitoring metrics associated with unsuccessful performance monitoring instances may be weighted by zero. In such cases, the respective non-zero weight applied to each per-instance performance monitoring metrics associated with a successful performance monitoring instance may be based on a respective distance (e.g., duration in time) between a respective second reference signal set associated with the successful performance monitoring instance and a respective first reference signal set associated with the successful performance monitoring instance.
[0133] For example, a first successful performance monitoring instance may be associated with a first distance between a respective second reference signal set associated with the first successful performance monitoring instance and a respective first reference signal set associated with the first successful performance monitoring instance. Additionally, a second successful performance monitoring instance may be associated with a second distance between a respective second reference signal set associated with the second successful performance monitoring instance and a respective first reference signal set associated with the second successful performance monitoring instance. In such cases, a first non-zero weight associated with the first successful performance monitoring instance may be greater than a second non-zero weight associated with the second successful performance monitoring instance based on the first distance being shorter than the second distance.
[0134] At 430, the UE 115-b may transmit a performance monitoring report associated with the performance monitoring window, where the performance monitoring report indicates one or more cumulative performance monitoring metrics associated with the multiple performance monitoring instances. In such cases, the one or more cumulative performance monitoring metrics may be based on a quantity of successful performance monitoring instances within the performance monitoring window, where a successful performance monitoring instance is a performance monitoring instance in which one or more events occur based on one or more respective predicted best beams. In some cases, the one or more cumulative performance monitoring metrics may include the one or more fourth cumulative performance monitoring metrics.
[0135] In some cases, the one or more cumulative performance monitoring metrics may include a cumulative performance monitoring metric that is based in equal part on each performance monitoring instance within the performance monitoring window. For example, the cumulative performance monitoring metric may include a first performance monitoring metric that is based on the quantity of successful performance monitoring instances within the performance monitoring window relative to a total quantity of eligible performance monitoring instances within the performance monitoring window. In some other examples, each successful performance monitoring instance of the quantity of successful performance monitoring instances may be associated with a respective per-instance performance monitoring metric, such that cumulative performance monitoring metric may include a second cumulative performance monitoring metric that is based on a sum of the respective per-instance performance monitoring metrics divided by the total quantity of eligible performance monitoring instances within the performance monitoring window.
[0136] Additionally, or alternatively, the multiple performance monitoring instances may be grouped into multiple performance monitoring instance sets (e.g., sets of prediction instances) , and the one or more cumulative performance monitoring metrics may include a respective third cumulative performance monitoring metric associated with each performance monitoring instance set among the multiple performance monitoring instance sets. In such cases, the respective cumulative performance monitoring metric associated with each performance monitoring instance set may be based on a respective quantity of successful performance monitoring instances within a respective performance monitoring instance set relative to a total quantity of respective eligible performance monitoring instances within the respective performance monitoring instance set. Additionally, or alternatively, each successful performance monitoring instance of the quantity of successful performance monitoring instances may be associated with a respective per-instance performance monitoring metric, where the respective third cumulative performance monitoring metric associated with each performance monitoring instance set may be based on a sum of respective per-instance performance monitoring metric associated with a respective performance monitoring instance set divided by a total quantity of respective eligible performance monitoring instances within the respective performance monitoring instance set.
[0137] Additionally, or alternatively, the multiple performance monitoring instances may be associated with one or more prediction sets. In such cases, the multiple performance monitoring instance sets may include a first performance monitoring instance set associated with respective first prediction instances in each of one or more prediction sets and may include a second performance monitoring instance set associated with respective second prediction instances in each of the one or more prediction sets.
[0138] In some cases, the one or more events may include 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.
[0139] Additionally, or alternatively, the one or more predicted best beams may include multiple (e.g., Top-K) predicted best beams, such that the one or more events includes the actual best beam (e.g., measured to have a highest signal quality out of at least the second set of beams) from among at least the second set of beams being within the multiple predicted best beams.
[0140] Additionally, or alternatively, the one or more predicted best beams may include a single (e.g., Top-1) predicted best beam that is predicted to have a highest signal quality out of the second set of beams, such that the one or more events includes the single predicted best beam being within one or more actual best beams (e.g., measured to have highest signal qualities out of at least the second set of beams) from among at least the second set of beams.
[0141] Additionally, or alternatively, the one or more predicted best beams may include the single predicted best beam that is predicted to have the highest signal quality out of the second set of beams, such that the one or more events includes a first measured signal quality associated with the single predicted best beam being within a first threshold deviation of a second measured signal quality of the actual best beam from among at least the second set of beams.
[0142] Additionally, or alternatively, the one or more predicted best beams include the multiple predicted best beams, such that the one or more events includes a highest measured signal quality associated with the multiple predicted best beams being within a second threshold deviation of a second measured signal quality of the actual best beam from among at least the second set of beam.
[0143] Additionally, or alternatively, the one or more predicted best beams may include the single predicted best beam that is predicted to have a highest signal quality out of the second set of beams, such that the one or more events includes a predicted signal quality associated with the single predicted best beam being within a third threshold deviation of a measured signal quality associated with the single predicted best beam.
[0144] Additionally, or alternatively, the one or more predicted best beams beams may include the multiple predicted best beams and a first predicted best beam of the multiple predicted best beams may be associated with a highest predicted signal quality out of the multiple predicted best beams. In such cases, the one or more events may include the highest predicted signal quality being within a fourth threshold deviation of a measured signal quality associated with the first predicted best beam.
