Abstract

Methods, systems, and devices for processing criteria for event driven channel state reporting are described. The described techniques provide for transmitting CSI reports based on when a UE determines that a trigger for an event condition has occurred. The trigger may be based on a determination that the channel associated with received reference signals is deficient in terms of quality. Upon determining that the trigger for the event condition has occurred, the UE may then generate a CSI report to transmit to the network entity. Additionally, the UE may determine an optimal CSI processing unit (CPU) value which may determine an amount of processing resources that the UE may utilize in generating the CSI reports.

Description

PROCESSING CRITERIA FOR EVENT DRIVEN CHANNEL STATE REPORTING
FIELD OF TECHNOLOGY
The following relates to wireless communications, including processing criteria for event driven channel state reporting.
BACKGROUND
Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .
Channel state information (CSI) resources (e.g., CSI-RS) may be measured by a UE to estimate channel quality between a base station and UE, where the channel quality may be indicated by measured parameters (e.g., channel quality indicator (CQI) , precoding matrix indicator (PMI) , rank indicator (RI) , reference signal received power (RSRP) ) . The UE may transmit a CSI report to the base station indicating the channel quality information that the base station may use for data transmissions. The base station may want to use this report for scheduling in the future. Conventional CSI reporting techniques are deficient.

The described techniques relate to improved methods, systems, devices, and apparatuses that support processing criteria for event driven channel state reporting. For example, the described techniques enable a user equipment (UE) to transmit channel state information (CSI) reports based on when (or if) a UE determines that a trigger for an event condition has occurred. The trigger may be based on a determination that the channel associated with received reference signals is deficient in terms of quality. Upon determining that the trigger for the event condition has occurred, the UE may then generate a CSI report to transmit to the base station. Additionally, the UE may determine an optimal CSI processing unit (CPU) value which may determine an amount of processing resources that the UE may utilize in generating the CSI reports. The CPU value may affect an amount of processing power in addition to providing a quantity of measurements and reports that it may generate.
A method for wireless communications by a user equipment (UE) is described. The method may include receiving, from a network entity, one or more reference signals via one or more beams, generating one or more channel state information (CSI) reports based on a first CSI processing unit (CPU) value and on one or more measurements of the one or more reference signals satisfying a measurement threshold that triggers an event condition, and transmitting, to the network entity, at least one of the one or more CSI reports in accordance with the first central processing unit (CPU) value and based on the one or more measurements satisfying the measurement threshold that triggers the event condition.
A UE for wireless communications is described. The UE may include one or more memories storing processor executable code, and one or more processors coupled with the one or more memories. The one or more processors may individually or collectively be operable to execute the code to cause the UE to receive, from a network entity, one or more reference signals via one or more beams, generate one or more CSI reports based on a first CSI processing unit (CPU) value and on one or more measurements of the one or more reference signals satisfying a measurement threshold that triggers an event condition, and transmit, to the network entity, at least one of the one or more CSI reports in accordance with the first CPU value and based on the one or  more measurements satisfying the measurement threshold that triggers the event condition.
Another UE for wireless communications is described. The UE may include means for receiving, from a network entity, one or more reference signals via one or more beams, means for generating one or more CSI reports based on a first CSI processing unit (CPU) value and on one or more measurements of the one or more reference signals satisfying a measurement threshold that triggers an event condition, and means for transmitting, to the network entity, at least one of the one or more CSI reports in accordance with the first CPU value and based on the one or more measurements satisfying the measurement threshold that triggers the event condition.
A non-transitory computer-readable medium storing code for wireless communications is described. The code may include instructions executable by one or more processors to receive, from a network entity, one or more reference signals via one or more beams, generate one or more CSI reports based on a first CSI processing unit (CPU) value and on one or more measurements of the one or more reference signals satisfying a measurement threshold that triggers an event condition, and transmit, to the network entity, at least one of the one or more CSI reports in accordance with the first CPU value and based on the one or more measurements satisfying the measurement threshold that triggers the event condition.

In some examples of the method, user equipment (UEs) , and non-transitory computer-readable medium described herein, transmitting the at least one of the one or more CSI reports may include operations, features, means, or instructions for transmitting one or more aperiodic CSI reports, semi-persistent CSI reports, or periodic CSI reports prior to one or more event-triggered CSI reports in accordance with the priority ordering.

DETAILED DESCRIPTION
A user equipment (UE) may use reference signals, such as channel state information (CSI) reference signals (CSI-RSs) to estimate channel quality between a base station and UE, and the UE may transmit a CSI report to a network entity  indicating the channel quality information. In some systems (e.g., a new radio (NR) wireless communication system) , there may be a CSI processing unit (CPU) value, where the CPU value may be equal to the number of simultaneous CSI calculations supported by the UE. The CPU value may be a calculation engine capable of performing CSI calculations or measurements that are reported in or indicated by the CSI report, which may be aperiodic, semi-persistent, periodic, event driven, etc.
CSI reporting may be performed on a periodic, semi-persistent, or an aperiodic basis when a network entity signals to a UE to transmit a report. This may lead to the CSI reporting periodicity being too long, which may result in outdated channel information. However, if CSI reporting is done too frequently, this may result in higher overhead and latency issues. Additionally, when generating a CSI report, the UE may allocate some portion of available CPUs to perform one or more CSI calculations for the CSI report. In some cases, there may not be enough CPUs available because the UE has already allocated some of the CPUs for performing ongoing CSI calculations for generating one or more other CSI reports. In other cases, there may an excess of CPUs allocated which does not utilize resources effectively.
To mitigate these issues, processing criteria for event driven channel state reporting may be employed. A UE may initiate a CSI reporting procedure based on its own determination that channel measurements have deteriorated such that a measurement threshold is satisfied (e.g., is exceeded or falls below) thus resulting in an CSI reporting event condition. Additionally, the UE may determine a CPU value which may determine an amount of processing resources that the UE may utilize in generating the CSI reports. The CPU value may affect an amount of processing power in addition to providing a quantity of measurements and reports that it may generate.
Particular aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in CSI processing, decrease processing time, and improve data throughput, among other advantages. As such, supported techniques may include improved network operations and, in some examples, may promote network efficiencies, among other benefits.
Aspects of the disclosure are initially described in the context of wireless communications systems. Further examples are then provided that illustrate CSI  processing techniques in transmitting CSI reports. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to processing criteria for event driven channel state reporting.
FIG. 1 shows an example of a wireless communications system 100 that supports processing criteria for event driven channel state reporting 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.
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) .
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.
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.
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.
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) .
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) ) .
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.
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.
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 test 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) .
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.
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.
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) .
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.
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) .
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.
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) ) .
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) .
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.
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.
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.
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.
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.
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.
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.
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) .
UE 115 may measure CSI-RS resources to estimate channel quality of a channel and that may be indicated by measured channel quality parameters (e.g., CQI, PMI, RI, RSRP) . UE 115 may transmit a CSI report to network entity 105 indicating the measured channel quality parameters for the CSI reference resource slot. Network entity 105 may use the CSI report for scheduling in the future. Additionally, or alternatively, UE 115 may initiate a CSI reporting procedure based on its own determination that channel measurements have deteriorated such that a measurement threshold is triggered thus resulting in an CSI reporting event condition. the channel associated with received reference signals is deficient in terms of quality. Upon determining that the trigger for the event condition has occurred, the UE may then generate a CSI report to transmit to the network entity 105. Additionally, the UE 115 may determine a CPU value which may correspond to an amount of processing resources that the UE may utilize in generating the CSI reports. The CPU value may affect an amount of processing power in addition to providing a quantity of measurements and reports that the UE 115 may generate.
FIG. 2 shows an example of a wireless communications system 200 that supports processing criteria for event driven channel state reporting in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may include network entity 105-a and UE 115-a, which may be examples of network entities 105 and UEs 115 as described with reference to FIG. 1. Network entity 105-a may serve a geographic coverage area 110-a. In some examples, network entity 105-a and UE 115-a may communicate via communication link 205. In some cases, UE-115-a  may implement an event driven channel state reporting to transmit to network entity 105-a a CSI report based on a triggered event condition and in accordance with a CPU value.
Network entity 105-a may transmit CSI reference signals 210 within one or more CSI resources for measurement by UE 115-a to estimate a channel quality of communication link 205 between network entity 105-a and UE 115-a. UE 115-a may transmit a CSI report 220 to network entity 105-a indicating the channel quality information that network entity 105-a may use for scheduling subsequent data transmissions. In some examples, UE 115-a may transmit CSI report 220 periodically, aperiodically, or on a semi-persistent basis to network entity 105-a. In other examples, UE 115-a may send CSI report 220 based on a triggered event condition at a UE. For example, UE 115-a may determine that reference signals 210 indicate that the channel is below a signal power or quality threshold. This power or quality threshold may be determined from various measurements such as signal-to-noise ratio (SNR) , reference signal received power (RSRP) , reference signal received quality (RSRQ) , or a combination thereof. Once UE 115-a determines that the measurement threshold has been satisfied, it may also indicate that an event condition has been triggered which initiates a CSI reporting procedure. This procedure may include UE 115-a signaling to network entity 105-a to signal uplink resources for UE 115-a to transmit a CSI report or it may include UE 115-a transmitting a CSI report utilizing previously scheduled resources.
UE 115-a may apply a priority rule for transmission of one or more CSI reports. This priority rule may be used by UE 115-a to prioritize the transmission of event-triggered CSI reports, periodic CSI reports, semi-persistent CSI reports, and aperiodic CSI reports. For example, a first prioritization rule may prioritize the transmission of aperiodic CSI reports, then event-triggered CSI reports, and then semi-persistent/periodic CSI reports. A second prioritization rule may prioritize the transmission of event-triggered CSI reports followed by any aperiodic CSI reports, semi-persistent CSI reports, and periodic CSI reports. A third prioritization rule may prioritize the transmission of any aperiodic CSI reports, semi-persistent CSI reports, and periodic CSI reports followed by event-triggered CSI reports. After determining the transmission priority, UE 115-a may then transmit the one or more CSI reports.
UE capability regarding configured CPU values 225 may also impact CSI reporting. A CPU value 225 may be equal to the number of simultaneous CSI calculations UE 115-a is capable of supporting at the same time. UE 115-a may be capable of a fixed amount of CSI calculations. UE 115-a may transmit to network entity 105-a an indication of a UE capability, where the capability indicates a plurality of CPU values 225 that UE 115-a is capable of implementing. CPU value 225 may be include both integer and fractional values. UE 115-a may determine an optimal CPU value 225 to utilize for the measurement of channel conditions and for the generation and transmission of CSI reports. For example, UE 115-a may utilize a lower CPU value 225 in instances where fewer measurements and CSI reports are sufficient, and may utilize a higher CPU value 225 in instances where greater measurements and CSI reports are required. UE 115-a may utilize different CPU values 225 in different instances of channel state measurement and CSI reporting based on varying circumstances. For example, CPU consumption may be less when the trigger for the event condition has not occurred as resources are only needed for measurement and not for reporting. Conversely, CPU consumption may be more when the trigger for the event condition has occurred and resources are requested for both measurement and for reporting.
FIG. 3A and FIG. 3B show examples of CSI processing configurations 300 and 350 that support processing criteria for event driven channel state reporting in accordance with one or more aspects of the present disclosure. The CPU processing configurations 300 and 350 may illustrate various instances of determining CPU values according to different channel state measurement scenarios.
CPU processing configuration 300 may illustrate two different scenarios for channel state measurement procedures. For example, scenario 310 may illustrate a scenario where UE 115 may only be conducting channel state measurements of a channel without generating any corresponding CSI reports. Under scenario 310, a corresponding CPU value, OCPU_meas_only, may indicate the CPU value that UE 115 may utilize during this given time period.
In another example, scenario 320 may illustrate a scenario where UE 115 may be conducting channel state measurements of a channel in addition to generating one or more corresponding CSI reports. Under scenario 320, a corresponding CPU value, OCPU_meas_and_report, may indicate the CPU value that UE 115 may utilize during  this given time period. As illustrated relative to scenario 310, scenario 320 may require a higher CPU value than that of scenario 310 due to the additional processing resources required for generating the CSI reports. The CPU values utilized by UE 115 may be both integer values and fractional values. Serving only as possible examples, CPU values may be 0, 1/2, 2/3, 1, 3/2, etc. Other CPU values may be available to UE 115.
CPU processing configuration 350 may illustrate a scenario 360 where UE 115 conducts channel state measurements of a channel, detects an event condition 370 being met, and then generates one or more corresponding CSI reports due to event condition 370 being satisfied. Under scenario 360, corresponding CPU values, OCPU_meas and OCPU_report, may indicate CPU values that UE 115 may utilize during this given time period. Here, the CPU value for conducting channel state measurements of a channel in addition to generating one or more corresponding CSI reports may be defined as two different CPU values. CPU value OCPU_meas may be utilized by UE 115 prior to event condition 370, and OCPU_report may be utilized by UE 115 after event condition 370 is detected.
In some examples, a total CPU value given a scenario where a UE 115 both conducts channel state measurements of a channel and then generates one or more corresponding CSI reports due to event condition being satisfied may be derived based on a quantity of CSI measurement-only instances (M) and a quantity of measurement-and-reporting instances (N) during a time period as follows:
In this example, a total CPU value is determined by combining separately calculated CPU values of a measurement only scenario with a measurement and report scenario.
In another example, a total CPU value given a quantity of CSI measurement-only instances (M) and a quantity of measurement-and-reporting instances (N) during a time period may be determined as follows:
In this example, a total CPU value is determined by jointly calculating CPU values of a measurement only scenario with a measurement and report scenario.
In some examples, one or more offsets may be introduced in calculating a total CPU value given a quantity of CSI measurement-only instances (M) and a quantity of measurement-and-reporting instances (N) during a time period. In this scenario, the two respective CPU values for OCPU_meas_only and OCPU_meas_and_report may be defined to be integers (i.e., OCPU_meas_only = o_meas and OCPU_meas_and_report = o_report (where o_meas∈ {0, 1, 2, . . . } , o_report∈ {0, 1, 2, . . . } ) , where the offset values, denoted as Offset_meas for measurement only and Offset_report for measurement &report, can be applied when the final CPU value is computed:
O_(Total_CPU_event_triggered) =O_ (CPU_meas_only) *M+Offset_meas+O_ (CPU_meas_and_report) *N+Offset_report
=o_meas*M+〖Offset〗_meas+o_report*N+〖Offset〗_report
In a first example of how the offsets may be utilized in determining a total CPU value based on a quantity of CSI measurement-only instances (M) and a quantity of measurement-and-reporting instances (N) during a time period:

In a second example of how the offsets may be utilized in determining a total CPU value based on a quantity of CSI measurement-only instances (M) and a quantity of measurement-and-reporting instances (N) during a time period:

In another example of utilizing offset values in calculating a total CPU value, a single CPU value and a single offset value may be defined where a single CPU is denoted OCPU_event_driven (= OCPU_meas_only = OCPU_meas_and_report) and an offset is represented as a function of both a quantity of CSI measurement-only instances (M) and a quantity of measurement-and-reporting instances (N) (i.e., Offset=func (M, N) ) , where the total CPU value is based on applying the same offset value to both the CSI measurement-only instances and the measurement-and-reporting instances.
In some examples, CPU values for OCPU_meas_only and OCPU_meas_and_report may be weighted in relation to one another. For example, a relationship between the two may exist such that OCPU_meas_only = ɑ *OCPU_meas_and_report where an instance if ɑ <=1 could  be considered to put more weight towards the CPU value associated with measurement-and-reporting instances.
In other examples, in scenarios where periodic, semi-persistent, and aperiodic CSI reporting (legacy reporting) coincide with an event-driven CSI report, a relationship between the two may exist such that OCPU_meas_and_report = β *OCPU_legacy where β is a weight that may be based on UE capability.
FIG. 4 shows an example of a process flow 400 that supports processing criteria for event driven channel state reporting in accordance with one or more aspects of the present disclosure. The process flow 400 may illustrate an example CSI processing procedure.
At 405, network entity 105-b may transmit, and UE 115-b may receive one or more reference signals via one or more beams of network entity 105-b.
At 410, UE 115-b may generate one or more CSI reports based on a triggered event condition at a UE 115-b. For example, UE 115-a may determine that the reference signals indicate that the channel is below a signal power or quality threshold. Once UE 115-b determines that the measurement threshold has been satisfied, it may also indicate that an event condition has been triggered which initiates the CSI report being generated. UE 115-b may generate the CSI report based on a first CPU value.
At 415, UE 115-b may transmit, and network entity 105-b may receive, the generated CSI reports in accordance with the first CPU value and the triggered event condition occurring.
At 420, network entity 105-b may transmit, and UE 115-b may receive one or more additional reference signals via one or more beams of network entity 105-b.
At 425, UE 115-b may generate one or more additional CSI reports based on an event condition at a UE 115-b occurring based on the measuring the one more additional reference signals. UE 115-b may have determined a second CPU value to utilize in generating the one or more additional CSI reports, where the second CPU value is different than the first CPU value.
At 430, UE 115-b may transmit, and network entity 105-b may receive, the additional generated CSI reports in accordance with the second CPU value and the triggered event condition occurring.
FIG. 5 shows a block diagram 500 of a device 505 that supports processing criteria for event driven channel state reporting in accordance with one or more aspects of the present disclosure. The device 505 may be an example of aspects of a UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communications manager 520. The device 505, or one or more components of the device 505 (e.g., the receiver 510, the transmitter 515, the communications manager 520) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
The receiver 510 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to processing criteria for event driven channel state reporting) . Information may be passed on to other components of the device 505. The receiver 510 may utilize a single antenna or a set of multiple antennas.

As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “acomponent” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “acomponent” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components”  subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure) , ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) , and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described  herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
