Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a first predictive measurement associated with a first channel state information (CSI) report and a second predictive measurement associated with a second CSI report. In some cases, the first CSI report and the second CSI report may be scheduled for processing or transmission during a first slot. The UE may transmit the first CSI report during the first slot based on a first priority level associated with the first CSI report based on a first set of one or more parameters corresponding to the first predictive measurement. The UE may drop the second CSI report based on a second priority level associated with the second CSI report based on a second set of one or more parameters corresponding to the second predictive measurement.
Description
The following relates to wireless communications, including inter-channel state information (CSI) priorities for temporal beam prediction reports.
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) .
The described techniques relate to improved methods, systems, devices, and apparatuses that support inter-channel state information (CSI) priorities for temporal beam prediction reports. For example, according to techniques described herein, a user equipment (UE) may receive control signaling indicating a first predictive measurement associated with a first CSI report and a second predictive measurement associated with a second CSI report. In some cases, the first CSI report and the second CSI report may be scheduled for processing or transmission during a same period of time (e.g., during a first slot) . The UE may transmit the first CSI report (e.g., or process the first CSI report) during the first slot according to a first priority level associated with the first CSI report
based on a first set of one or more parameters corresponding to the first predictive measurement. The UE may drop the second CSI report according to a second priority level associated with the second CSI report based on a second set of one or more parameters corresponding to the second predictive measurement. The first priority level may have a higher priority than the second priority level.
A method for wireless communications by a UE is described.

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 (e.g., operatively, communicatively, functionally, electronically, or electrically) the one or more memories.

A non-transitory computer-readable medium storing code for wireless communications is described.

In some wireless communications systems, a user equipment (UE) may transmit channel state information (CSI) reports (e.g., to a network entity) . The CSI report may include one or more predictive measurements. As described herein, a predictive measurement may refer to one or more measurements or predicted measurements regarding a future temporal occasion, one or more measurements or predicted measurements for a current or future temporal occasion based on buffered historical measurement results, or any combination thereof. The UE may generate the CSI reports based on predictive measurements for a future temporal occasion. In some examples, the CSI reports may include channel characteristics for future temporal occasions. Additionally, or alternatively, the CSI report may be based on buffered historical measurement results associated with multiple measurements for previous temporal occasions. The UE may be configured to process or transmit multiple predictive CSI reports in the same slot. However, the UE may not have sufficient processing capability to successfully buffer, process, or generate both of the conflicting CSI reports in the same slot. In some examples, the UE may not be able to multiplex and transmit both of the conflicting CSI reports in the same slot. In either case, without a mechanism to determine a priority of the conflicting predictive CSI reports, the UE may fail to complete or transmit one of the two CSI reports, or may transmit a CSI
report (e.g., and drop another) that does not include the information that would be most valuable to the network.
According to techniques described herein, the UE may prioritize a first predictive CSI report over a second CSI report. The UE may prioritize the first CSI report based on a first priority level associated with the first CSI report being higher than a second priority level associated with the second CSI report. The first CSI report and the second CSI report may be configured to update within the same slot or be multiplexed into a same uplink transmission (e.g., a PUSCH transmission or a PUCCH transmission) . In some cases, the first CSI report and the second CSI report may both include predicted channel characteristics regarding future temporal occasions. In some cases, the first CSI report and the second CSI report may be configured to buffer or process measurement results regarding reference signals (RSs) (e.g., synchronization signal blocks (SSBs) , CSI-RSs, or demodulation RSs (DMRSs) ) associated with historical measurement occasions to derive an associated report quantity.
In some cases, the UE may prioritize the first CSI report associated with a future temporal occasion over the second CSI report associated with a future temporal occasion based on the priority levels. The UE may obtain the priority levels associated with the first CSI report and the second CSI report. For example, the priority level may be based on the key characteristics being reported in the CSI report. The first CSI report may report beam-failure, blockage, or radio link failure (RLF) and may be prioritized over the second CSI report, which may report layer one reference signal received power (L1-RSRP) , layer one signal to interference noise ratio (L1-SINR) , or Top-K-Resources. In some examples, the priority level may be based on the temporal occasion associated with the predicted channel characteristics addressed in the CSI report. For example, the first CSI report associated with a first temporal occasion may be prioritized over the second CSI report associated with a second temporal occasion that occurs after the first temporal occasion. In some examples, the priority level may be based on whether one or more prediction targets of the respective CSI reports are based on actually transmitted RSs or virtual resources (e.g., not actually transmitted signals received via resources) .
In some cases, the UE may prioritize CSI reports associated with buffered historical measurement results. For example, the priority level may be based on the CSI
reports corresponding to the earliest historical measurement occasion. In some examples, the priority level corresponding to the CSI reports may be based on control signaling from the network entity that indicates a preference for the first CSI report or a first artificial intelligence (AI) or machine learning (ML) model associated with the first CSI report. In some examples, the CSI reports may be based on a pre-reported preference at the UE for the first CSI report or a first AI or ML model associated with the first CSI report.
Aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in predictive CSI report prioritization. The described techniques may result in more improved communication reliability, more efficient utilization of communication resources, improved coordination between devices, and improved utilization of processing capability.
Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are described with reference to communication timelines 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 inter-CSI priorities for temporal beam prediction reports.
FIG. 1 shows an example of a wireless communications system 100 that supports inter-CSI priorities for temporal beam prediction reports 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 adaption 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 multimedia/entertainment device (e.g., a radio, a MP3 player, or a video device) , a camera, a gaming device, a navigation/positioning device (e.g., GNSS (global navigation satellite system) devices based on, for example, GPS (global positioning system) , Beidou, GLONASS, or Galileo, or a terrestrial-based device) , a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet) ) , a drone, a robot/robotic device, a vehicle, a vehicular device, a meter (e.g., parking meter, electric meter, gas meter, water meter) , a monitor, a gas pump, an appliance (e.g., kitchen appliance, washing machine, dryer) , a location tag, a medical/healthcare device, an implant, a sensor/actuator, a display, or any other suitable device configured to communicate via a wireless or wired medium, 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 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) .
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, RSs, 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.
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.
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 CSI 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) .
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, RSs, 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) .
In some examples, the UE 115 may transmit a CSI report (e.g., to a network entity 105) . The CSI report may include predictive channel characteristics associated with a first set of beams. The predictive channel characteristics may be based on measurement results for a second set of beams or historical measurement results for the second set of beams. The UE 115 or the network entity 105 may use an AI or ML model
to generate the predictive channel characteristics for the first set of beams. In some cases, the second set of beams may be a different set of beams compared to the first set of beams or a subset of the first set of beams. In some other cases, the first set of beams and the second set of beams may be the same set. The AI or ML model may consider measurement results associated with one or more latest measurement instances. The AI or ML model may use L1-RSRP measurements based on the second set of beams, L1-RSRP measurements based on the second set of beams and assistance information, or L1-RSRP measurements based on the second set of beams corresponding to downlink transmission or receive beam identification. The AI or ML model may generate one or more predictions for one or more future time instances. The UE 115 or the network entity 105 may generate predictive channel characteristics based on the one or more predictions. For example, a wireless device (e.g., the UE 115) may support downlink transmission beam prediction techniques, which may include a UE-sided model (e.g., an AI or ML model) , a network-sided model (e.g., an AI or ML model) , or both. Such a UE 115 may support spatial-domain downlink transmit beam prediction for a first set (e.g., set A) of beams based on measurement results of a second set (e.g., set B) of beams (e.g., a first beam management case) . The UE 115 may support temporal downlink transmit beam predictions for asset A beams based on the historical measurement results of set B beams (e.g., a second beam management case) . The UE 115 may support signaling and mechanisms to facility LCM operations specific to beam management use cases, and may support consistency between training and inferences (e.g., for the AI or ML model) regarding network-side conditions for inference at the UE 115.
According to techniques described herein, the UE 115 may prioritize a first predictive CSI report over a second CSI report. The UE 115 may prioritize the first CSI report based on a first priority level associated with the first CSI report being higher than a second priority level associated with the second CSI report. The first CSI report and the second CSI report may be configured to update within the same slot or be multiplexed into a same uplink transmission (e.g., a PUSCH transmission or a PUCCH transmission) . In some cases, the first CSI report and the second CSI report may both include predicted channel characteristics regarding future temporal occasions. In some cases, the first CSI report and the second CSI report may be configured to buffer or
process measurement results regarding RSs (e.g., SSBs, CSI-RSs, or DMRSs) associated with historical measurement occasions to derive an associated report quantity.
In some cases, the UE 115 may prioritize the first CSI report associated with a future temporal occasion over the second CSI report associated with a future temporal occasion based on the priority levels. The UE 115 may obtain the priority levels associated with the first CSI report and the second CSI report. For example, the priority level may be based on the key characteristics being reported in the CSI report. The first CSI report may report beam-failure, blockage, or RLF and may be prioritized over the second CSI report, which may report L1-RSRP, L1-SINR, or Top-K-Resources. In some examples, the priority level may be based on the temporal occasion associated with the predicted channel characteristics addressed in the CSI report. For example, the first CSI report associated with a first temporal occasion may be prioritized over the second CSI report associated with a second temporal occasion that occurs after the first temporal occasion. In some examples, the priority level may be based on whether one or more prediction targets of the respective CSI reports are based on actually transmitted RSs or virtual resources (e.g., not actually transmitted signals received via resources) .
In some cases, the UE 115 may prioritize CSI reports associated with buffered historical measurement results. For example, the priority level may be based on the CSI reports corresponding to the earliest historical measurement occasion. In some examples, the priority level corresponding to the CSI reports may be based on control signaling from the network entity that indicates a preference for the first CSI report or a first AI or ML model associated with the first CSI report. In some examples, the CSI reports may be based on a pre-reported preference at the UE 115 for the first CSI report or a first AI or ML model associated with the first CSI report.
FIG. 2 shows an example of a communication timeline 200 and a communication timeline 201 that supports inter-CSI priorities for temporal beam prediction reports in accordance with one or more aspects of the present disclosure. In some examples, communication timeline 200 and the communication timeline 201 may implement, or be implemented by, aspects of wireless communication system 100. For example, a UE 115 and a network entity 105, which may be examples of corresponding
devices described with reference to FIG. 1, may communicate with each other according to the communication timeline 200 or the communication timeline 201.
In some wireless communications systems, a UE 115 may transmit a CSI report 205 (e.g., to a network entity 105) . The CSI report 205 may include one or more predictive measurements. As described herein, a predictive measurement may refer to one or more measurements or predicted measurements regarding a future temporal occasion, one or more measurements or predicted measurements for a current or future temporal occasion based on buffered historical measurement results, or any combination thereof.
In some examples, as illustrated with reference to communication timeline 200, the UE 115 may generate the CSI report 205-a based on predictive measurements for a future temporal occasion. In some examples, the CSI report 205-a may include channel characteristics for future temporal occasion. For example, the UE may predict future channel characteristics of a first set of beams using measurement results of a second set of beams or historical measurement results for the second set of beams as described in greater detail with reference to FIG. 1. The CSI report 205-a may be an example of or may include temporal beam prediction CSI reports. The CSI report 205-amay include a report quantity associated with predicted channel characteristics 210 for a future temporal occasion. The future temporal occasion may occur later than the slots carrying the CSI report 205-a. For example, the UE 115 may transmit or process the CSI report 205-a including predicted channel characteristics 210. The predicted channel characteristics 210 may include L1-RSRPs, L1-SINRs, Top-K-Resources in terms of L1-RSRP/L1-SINR, beam-failure, beam blockage, or RLF, among other examples. The UE 115 may transmit the CSI report 205-a during temporal occasion 215-a (e.g., a first slot) . The predicted channel characteristics 210 may be for temporal occasion 215-b (e.g., a second slot) , which may occur after temporal occasion 215-a.
Additionally, or alternatively, as illustrated with reference to the communication timeline 201, the CSI report 205-b may be based on buffered historical measurement results associated with multiple measurements for previous temporal occasions 215. In other words, the CSI report 205-b may be generated by the UE 115 using buffered or processed historical measurement results (e.g., historical measurements 220) regarding multiple measurement occasions (e.g., one or more
measurement occasions 215-c) that occur before the slots carrying the CSI report 205-b (e.g., temporal occasion 215-a) . For example, the UE 115 may use historical measurements 220 to generate a current CSI report 205-b (e.g., indicating predicted channel characteristics for a current temporal occasion 215-a, or indicating predicted channel characteristics for a subsequent temporal occasion 215-b) . The CSI report 205-b may include predicted channel characteristics 210 based on the historical measurements 220 for current channel characteristics or future channel characteristics.
In some examples, predictive measurements may include a combination of historical measurements 220 and predicted channel characteristics 210. For example, a CSI report 205 may be based on or include buffered historical measurements 220 from one or more previous temporal occasions 215-c, and predicted channel characteristics for a future temporal occasion 215-b. For instance, the UE 115 may generate the CSI report 205 based on historical measurements, current measurements, an AI or ML model for subsequent beams or temporal occasions 215, or any combination thereof.
The UE 115 may be configured to process or transmit multiple predictive CSI reports 205 in the same temporal occasion 215 (e.g., in the same slot) . The UE 115 may not have sufficient processing capability to successfully buffer, process, or generate both of the conflicting CSI reports 205. In some examples, the UE 115 may not be able to multiplex and transmit both of the conflicting CSI reports 205. In either case, without a mechanism to determine a priority of the conflicting predictive CSI reports 205, the UE 115 may fail to complete or transmit one of the two CSI reports 205 (e.g., in which case a higher priority CSI report 205, or a CSI report 205 including more relevant information) may be dropped or may fail. In some examples, without a mechanism to determine a priority of the conflicting predictive CSI reports 205, the UE 115 may attempt to process or transmit both of the conflicting CSI reports 205, in which case one or both of the CSI reports 205 may fail (e.g., the UE 115 may not be able to buffer or process one or both CSI reports 205, or may fail to transmit one or both of the CSI reports 205) .
According to techniques described herein, a UE 115 may prioritize a first predictive CSI report 205 over a second CSI report 205. The UE 115 may prioritize the first CSI report 205 based on a first priority level associated with the first CSI report 205 being higher than a second priority level associated with the second CSI report 205.
The first CSI report 205 and the second CSI report 205 may be configured to update within the same slot or be multiplexed into a same uplink transmission (e.g., a PUSCH transmission or a PUCCH transmission) . In some cases, the first CSI report 205 and the second CSI report 205 may both include predicted channel characteristics 210 regarding future temporal occasions. In some cases, the first CSI report 205 and the second CSI report 205 may be configured to buffer or process measurement results regarding RSs (e.g., SSBs, CSI-RSs, or DMRSs) associated with historical measurement occasions to derive an associated report quantity.
In some cases, the UE 115 may prioritize the first CSI report 205 associated with a future temporal occasion over the second CSI report 205 associated with a future temporal occasion based on the priority levels obtained for each of the conflicting CSI reports 205. For example, the priority level may be based on the key characteristics being reported in the CSI report 205 (e.g., L1-RSRPs, L1-SINR, Top-K-resources, beam-failure or blockage, RLF) . The first CSI report 205 may report beam-failure, blockage, or RLF and may be prioritized over the second CSI report 205, which may report L1-RSRP, L1-SINR, or Top-K-Resources, as described in greater detail with reference to FIG. 3. In some examples, the priority level may be based on the temporal occasion 215 associated with the predicted channel characteristics 210 addressed in the CSI report 205. For example, the first CSI report 205 associated with a first temporal occasion 215 may be prioritized over the second CSI report 205 associated with a second temporal occasion 215 that occurs after the first temporal occasion 215, as described in greater detail with reference to FIG. 4. In some examples, the priority level may be based on whether one or more prediction targets of the respective CSI reports are based on actually transmitted RSs or virtual resources (e.g., not actually transmitted signals received via resources) .
In some other cases, the UE 115 may prioritize a CSI report 205 associated with buffered historical measurement results based on the obtained priority levels of the conflicting CSI reports. For example, the priority levels may be based on which historical measurement occasions should be buffered or processed for the CSI report 205. The first CSI report 205 corresponding to an earlier historical measurement occasion may be prioritized over the second CSI report 205 corresponding to a later historical measurement occasion, as described in greater detail with reference to FIG. 5.
In some examples, the priority levels for the conflicting CSI reports may be based on the type of measurement results buffered or processed for the CSI report 205 (e.g., L1-RSRPs, L1-SINRs, angles of arrival (AoAs) , angles of departure (AoDs) , raw channel responses) or the RS type (e.g., SSBs, CSI-RSs, DMRSs) associated with the historical measurement occasions. The priority levels may be based on a control signal from the network entity 105 that indicates a preference for the first CSI report 205 or a first AI or ML model associated with the first CSI report 205. The CSI reports 205 may be based on a pre-reported preference at the UE 115 for the first CSI report 205 or a first AI or ML model associated with the first CSI report 205.
The UE 115 may determine to drop one of the conflicting CSI reports 205 based on determining the respective priority levels (e.g., the UE 115 may drop the second CSI report 205 based on determining that the first CSI report 205 has a higher priority level than the second CSI report 205) . As described herein, dropping a CSI report may include refraining from processing the measurement report (e.g., the UE 115 may stop buffering relevant measurements or data, stop generating report quantities, stop performing active measurements, stop generating the report using an AI/ML model, among other examples) , or may include refraining from transmitting a lower priority CSI report 205 (e.g., refraining from actively transmitting or multiplexing one of the conflicting CSI reports 205) . For example, the UE 115 may stop processing the second CSI report 205 if the first CSI report 205 and the second CSI report 205 are scheduled to be processed in the same slot (e.g., during the same temporal occasion 215) . The UE 115 may determine to drop the second CSI report 205 (e.g., may refrain from transmitting the second CSI report 205) if the second CSI report 205 and the first CSI report 205 are scheduled to be transmitted in the same slot or multiplexed into the same uplink transmission. The UE 115 may stop processing or not transmit the second CSI report 205 based on the first priority level associated with the first CSI report 205 being higher than the second priority level associated with the second CSI report 205.
In some cases, the UE 115 may use the priority levels associated with the first CSI report 205 and the second CSI report 205 for comparison with other CSI reports 205 that are also configured to be processed in the same slot or configured to be multiplexed into the same uplink transmission to determine whether to stop processing or drop one or more CSI reports 205. Such other CSI reports 205 may not carry
predicted channel characteristics 210 regarding future temporal occasions or based on historical measurements.
The priority level for a given CSI report 205 (e.g., Pr iiCSI) may be calculated using the following equation:
Equation 1: PriiCSI (y, k, c, s, f) =2NCellsMsy+NCellsMsk+Msc+s+f
According to Equation 1, c represents a server cell identification, NCells represents a threshold (e.g., maximum) number of serving cells (e.g., as indicated by an RRC parameter corresponding to the maximum number of serving cells) , s represents a report configuration identification corresponding to a CSI report 205 setting (e.g., the report configuration identification indicates what resource configuration may be used for the measurements associated with the CSI report 205) , Ms represents a threshold (e.g., maximum) number of CSI report configuration (e.g., as indicated by an RRC parameter corresponding to the maximum number of CSI report configuration) , and f may represent a priority parameter f corresponding to the predictive CSI report. The priority parameter f is described in greater detail with reference to FIGs. 3–5. The priority parameter f may be associated with the priority level of a predictive CSI report 205. The priority parameter f may be configured by the network entity 105 or predefined at the UE 115, or defined in one or more standards documents. In some examples, the UE 115 may calculate a priority level for each conflicting CSI report 205 according to Equation 1 (e.g., in which case, the priority level of each CSI report 205 may be determined by the multiple inputs) . In some cases, the parameters y, k, c, and s may be the same value for the first CSI report 205 and the second CSI report 205. The priority parameter f may be used to prioritize one of the CSI reports 205 over the over CSI report 205 (e.g., if all other factors are equal, than the priority parameter f for predictive CSI reports may be the determining factor for calculating a priority level for a given CSI report according to Equation 1) . In some cases, a lower PriiCSI value associated with the CSI report 205 may correspond with a higher priority. If the parameters y, k, c, and s have the same value, the CSI report 205 corresponding the lower priority parameter f may be prioritized. In some examples, a lower value of f may indicate a higher priority level. Or, in some examples, a higher value of f may indicate a higher priority.
The UE 115 may drop (e.g., refrain from sending, refrain from processing, refrain from completing, stop sending, stop processing, stop completing, withdraw, delete, or hold off) the second CSI report 205 based on the priority levels associated with the first CSI report 205 being higher than the priority level associated with the second CSI report 205. In some cases, dropping the second CSI report 205 may be an example of transmitting the first CSI report 205 during the slot configured to transmit both the first CSI report 205 and the second CSI report 205, as described in greater detail with reference to FIGs. 3–6. In other words, the second CSI report 205 may not be transmitted. In some cases, dropping the second CSI report 205 may be an example of stopping or delaying the processing of historical measurement results associated with the second CSI report 205 during the temporal occasions, as described in greater detail with reference to FIGs. 3–6. In some such cases, the historical measurement results associated with the second CSI report 205 may overwritten while the historical measurement results associated with the first CSI report 205 may be processed.
FIG. 3 shows an example of a communication timeline 300 that supports inter-CSI priorities for temporal beam prediction reports in accordance with one or more aspects of the present disclosure. In some examples, communication timeline 300 may implement aspects of, or be implemented by aspects of, the wireless communication system 100, the communication timeline 200, or the communication timeline 201. For example, a UE 115 and a network entity 105, which may be examples of corresponding devices described with reference to FIGs. 1–2, may communicate with each other according to the communication timeline 300.
The UE 115 may be configured to transmit a first CSI report 305-a and a second CSI report 305-b during the same temporal occasion 315-a (e.g., slot) . The first CSI report 305-a may include first predicted channel characteristics 310-a and the second CSI report 305-b may include second predicted channel characteristics 310-b. The first predicted channel characteristics 310-a and the second predicted channel characteristics 310-b may be associated with temporal occasion 315-b. The predicted channel characteristics 310 may include one or more L1-RSRPs, L1-SINRs, Top-K-resources, indications of beam-failure, indications of blockage, or indications of RLF. The UE 115 may prioritize the first CSI report 305-a over the second CSI report 305-b based on a first priority level corresponding to the first CSI report 305-a and a second
priority level corresponding to the second CSI report 305-b, as described in greater detail with reference to FIG. 2.
The priority levels may be based on the contents of the predicted channel characteristics 310 associated with the CSI report 305. The priority levels may be based on key characteristics being reported in the CSI reports 305 (e.g., L1-RSRPs, L1-SINR, Top-K-resources, beam-failure, blockage, or RLF) . For example, the first CSI report 305-a may report beam-failure, blockage, or RLF and may be prioritized over the second CSI report 305-b, which may report L1-RSRP, L1-SINR, or Top-K-Resources associated with L1-RSRP or L1-SINR. For example, predictive CSI reports 305 including an indication of beam-failure, blockage, or RLF, may correspond to a higher priority level compared to predictive CSI reports 305 including an indication of L1-RSRPs, L1-SINRs, or Top-K-resources in terms of L1-RSRP or L1-SINR. For example, the report contents that have a greater impact on performance may be prioritized over report contents that have less of an impact on performance issues. Thus, predicted channel characteristics 310-a associated with beam-failure, blockage, or RLF may introduce more severe performance issues than predicted channel characteristics 310-b, and thus, the CSI report 305-a may correspond to a higher priority level.
In some cases, predictive CSI reports 305 including L1-RSRPs, may correspond to a higher priority level compared to predictive CSI reports 305 including L1-SINRs or Top-K-resources in terms of L1-RSRP or L1-SINR. Predictive CSI reports 305 including L1-RSRPs or L1-SINRs, may correspond to a higher priority level compared to predictive CSI reports 305 including Top-K-resources in terms of L1-RSRP or L1-SINR.
The priority level may be calculated based on a priority parameter f, as described in greater detail with reference to FIG. 2. The priority parameter f (e.g., f1) may be based on the key characteristics (e.g., the predicted channel characteristics 310) being reported in the CSI reports 305. In some cases, the priority parameter f may be configured by a network entity 105, defined in one or more standards documents, or otherwise predefined. In some cases, the priority parameter f may be set (e.g., via network configuration or as defined in one or more standards) to increase sequentially for CSI reports 305 carrying predicted future values as follows: beam-failure, blockage, RLF results, L1-RSRPs, L1-SINRs, and Top-K-resources. In some examples, the
priority parameter f may be set to increasing values (e.g., via network configuration or as defined in one or more standards documents) for CSI reports 305 carrying predicted future values as follows: L1-RSRPs vs. L1-SINRs, sequentially. In some examples, the priority parameter f may be set to increasing values (e.g., via network configuration or as defined in one or more standards documents) for CSI reports 305 carrying predicted future values as follows: L1-RSRPs/L1-SINRs vs. Top-K-Resources in terms of L1-RSRPs/L1-SINRs, sequentially. Thus, in some cases, the priority parameter f may indicate a higher priority for CSI reports 305 including beam-failure, blockage, or RLF results compared to CSI reports 305 including L1-RSRPs, L1-SINRs, or Top-K-resources. Additionally, or alternatively, the priority parameter f may indicate a higher priority for CSI reports 305 including L1-RSRPs compared to CSI reports 305 including L1-SINRs. Additionally, or alternatively, the priority parameter f may indicate a higher priority for CSI reports 305 including L1-RSRPs or L1-SINRs compared to CSI reports 305 including Top-K-resources in terms of L1-RSRPs or L1-SINRs.
For example, the UE 115 may be configured to transmit a first CSI report 305-a and a second CSI report 305-b during the same temporal occasion 315-a (e.g., slot) . The first CSI report 305-a may correspond to a first priority level based on a first priority parameter f, where the first priority parameter f is based on the predicted channel characteristics 310-a (e.g., beam-failure, blockage, or RLF) . The second CSI report 305-b may correspond to a second priority level based on a second priority parameter f, where the second priority parameter f is based on the predicted channel characteristics 310-b (e.g., L1-RSRPs, L1-SINRs, or Top-K-resources) . The first priority parameter f may be smaller than the second priority parameter f based on the predicted channel characteristics 310-a associated with beam-failure, blockage, or RLF being configured with a smaller priority parameter f than predicted channel characteristics 310-b including L1-RSRPs, L1-SINRs, or Top-K-resources. The first priority level may be higher than the second priority level based on the first priority parameter f being smaller than the second priority parameter f. The UE 115 may transmit the first CSI report 305-a during the temporal occasion 315-a based on the first priority level being higher than the second priority level. The UE 115-a may drop the CSI report 305-b based on the first priority level being higher than the second priority
level as described in greater detail with reference to FIG. 2. In some examples, a higher value of f may indicate a higher priority level.
FIG. 4 shows an example of a communication timeline 400 that supports inter-CSI priorities for temporal beam prediction reports in accordance with one or more aspects of the present disclosure. In some examples, communication timeline 400 may implement aspects of, or be implemented by aspects of, the wireless communication system 100, the communication timeline 200, the communication timeline 201, or the communication timeline 300. For example, a UE 115 and a network entity 105, which may be examples of corresponding devices described with reference to FIGs. 1–3, may communicate with each other according to the communication timeline 400.
The UE 115 may be configured to transmit a first CSI report 405-a and a second CSI report 405-b during the same temporal occasion 415-a (e.g., slot) . The first CSI report 305-a may include first predicted channel characteristics 410-a and the second CSI report 405-b may include second predicted channel characteristics 410-b. The UE 115 may prioritize the first CSI report 405-a over the second CSI report 405-b based on a first priority level associated with the first CSI report 405-a and a second priority level corresponding to the second CSI report 405-b, as described in greater detail with reference to FIG. 2.
The priority level may be based on the temporal occasion associated with the respective predicted channel characteristics 410 addressed in the CSI reports 405. For example, the first CSI report 405-a carrying predicted channel characteristics 410-b associated with a first temporal occasion 415-b may be prioritized over the second CSI report 405-b carrying predicted channel characteristics 410-b associated with a second temporal occasion 415-a (e.g., occurring after the first temporal occasion 415-b) . In other words, the predictive CSI report 405 including predicted channel characteristics 410 associated with a first earliest future temporal occasion that is closer to the considered slot for updating or reporting the CSI report 405 (e.g., temporal occasion 415-a) , may correspond to a higher priority level compared to a predictive CSI report 405 including predicted channel characteristics 410 associated with a second earliest future temporal occasion that is further away from the considered slot for updating or reporting the CSI report 405. The predictive CSI report 405 including predicted channel characteristics 410 associated with a first earliest future temporal occasion that is closer
to the considered slot for updating or reporting the CSI report 405 may be more relevant to (e.g., more urgent for) upcoming beam scheduling or beam decisions.
The priority level may be calculated based on a priority parameter f, as described in greater detail with reference to FIG. 2. The priority parameter f (e.g., f2) for a CSI report 405 may be based on the earliest future temporal occasion associated with the predicted channel characteristics 410. The priority parameter f may be set to increasing values (e.g., as configured by the network or according to one or more standards documents) for the further earliest future temporal occasions addressed by the relevant CSI report 405.
For example, the UE 115 may be configured to generate or transmit a first CSI report 405-a and a second CSI report 405-b during the same temporal occasion 415-a (e.g., slot) . The first CSI report 405-a may be associated with a first priority level based on a first priority parameter f, where the first priority parameter f is based on a first earliest future temporal occasion addressed by the CSI report 405-a (e.g., temporal occasion 415-b) . The second CSI report 305-b may be associated with a second priority level based on a second priority parameter f, where the second priority parameter f is based on a second earliest future temporal occasion addressed by the CSI report 405-b (e.g., temporal occasion 415-c) . The first priority parameter f may be smaller than the second priority parameter f based on the first earliest future temporal occasion 415-b being closer to the temporal occasion 415-a than the second earliest future temporal occasion 415-c. The first priority level may be higher than the second priority level based on the first priority parameter f being smaller than the second priority parameter f. The UE 115 may transmit the first CSI report 405-a during the temporal occasion 415-abased on the first priority level being higher than the second priority level. The UE 115 may drop the CSI report 405-b based on the first priority level being higher than the second priority level, as described in greater detail with reference to FIG. 2.
Additionally, or alternatively, the priority levels of conflicting CSI reports 405 may be based on predicted targets associated with the CSI reports 405. For instance, the first CSI report 405-a with a first prediction target associated with actually transmitted RSs (e.g., SSBs/CSI-RSs/DMRSs) , may be associated with a higher priority level compared to the second CSI report 405-b with a second prediction target associated with virtual resources (e.g., via which signals are not actually transmitted) .
The second CSI report 405-b may be scheduled later without associating actually transmitted RSs. The priority parameter f (e.g., f3) , may be a smaller value for CSI reports 405 with the first prediction target associated with actually transmitted RSs. The priority parameter f may be a larger value for CSI reports 405 the second prediction target associated with virtual resources. For example, the priority parameter f may be set to larger or smaller values (e.g., via network configuration or as defined in one or more standards documents) for CSI reports 405 with a prediction target that is associated with actually transmitted RSs (e.g., SSBs/CSI-RSs/DMRSs) vs. virtual resources that are not actually transmitted, respectively.
FIG. 5 shows an example of a communication timeline 500 that supports inter-CSI priorities for temporal beam prediction reports in accordance with one or more aspects of the present disclosure. In some examples, communication timeline 500 may implement aspects of, or be implemented by aspects of, the wireless communication system 100, the communication timeline 200, the communication timeline 201, the communication timeline 300, or the communication timeline 400. For example, a UE 115 and a network entity 105, which may be examples of corresponding devices described with reference to FIGs. 1–4, may communicate with each other according to the communication timeline 500.
In some examples, the UE 115 may prioritize a first CSI report 505 associated with buffered historical data (e.g., historical measurement results 510) based on the respective priority levels of conflicting CSI reports 505. For example, the priority levels of conflicting CSI reports 505 may be based on which historical measurement occasions should be buffered or processed for the CSI report 505. For example, the UE 115 may perform one or more historical measurements (e.g., generating historical measurement results, such as the historical measurement results 510) via one or more measurement occasions. Similarly, the second CSI report 505-b may also perform one or more historical measurements (e.g., generating historical measurement results, such as the historical measurement results 520) via one or more measurement occasions. The UE 115 may buffer some or all of the historical measurement results, including the historical measurement results 510 and the historical measurement results 520. As described herein, the UE 115 may determine which CSI report 505 to transmit when both CSI reports are scheduled to buffer or process the measurement results (e.g.,
regarding SSBs, CSI-RSs, DMRSs, or the like, with respect to multiple historical measurement occasions to derive associated report quantities) within a same temporal occasions 515 (e.g., slot) . In some examples, the UE 115 may determine priority levels for the conflicting CSI reports 505 based on which historical measurement occasion should be buffered or processed for a given CSI report 505, what measurement results in terms of measurement type or in terms of RS type associated with historical measurement occasions should be buffered or processed for the given CSI report 505.
In some examples, the first CSI report 505-a corresponding to an earlier historical measurement occasion may be prioritized over the second CSI report 505-b corresponding to a later historical measurement occasion. In other words, the CSI report 505-a associated with a first earliest historical measurement occasion (e.g., for the historical measurement results 510) that is configured to be buffered or processed earlier, may have a higher priority level compared to the CSI report 505-b associated with a second earliest historical measurement occasion (e.g., for the historical measurement result 520) that is configured to be buffered or processed later. The UE 115 may have limited buffer capacity for each CSI report 505. The UE 115 may drop the buffered measurement results for the first CSI report 505-a sooner than the buffered measurement results for the second CSI report 505-b. In other words, the UE 115 may prioritize processing the first CSI report 505-a based on the buffer for the first CSI report 505-a including more historical measurements results 510 which may be more likely to be dropped due to the buffer capacity if the CSI report is not transmitted. The UE 115 may drop the second CSI report 505-b based on the priority levels, as described in greater detail with reference to FIG. 2.
Additionally, or alternatively, if the historical measurement occasions associated with the second CSI report 505-b are a subset of the corresponding historical measurement occasions of the first CSI report 505-a, the first prediction report may correspond to a higher priority level comparing to the second CSI report 505-b. The UE 115 may drop the buffered measurement results for the first CSI report 505-a sooner than the second CSI report 505-b. In other words, the UE 115 may prioritize processing the first CSI report 505-a based on the buffer for the first CSI report 505 including more historical measurements results 510 which may be more likely to be dropped due to the buffer capacity.
The UE 115 may determine to stop processing the second CSI report 505-b if the first CSI report 505-a and the second CSI report 505-b are configured to be processed in the same during the same temporal occasion 515 (e.g., the same slot) based on the priority levels associated with the CSI reports 505.
The priority level may be calculated based on a priority parameter f (e.g., f4) as described in greater detail with reference to FIG. 2. In some examples, the priority parameter f for a CSI report 505 may be based on the historical measurement results 510 associated with the CSI report 505. In some cases, the priority parameter f may be set to smaller values for CSI reports 505 associated with an earliest historical measurement occasion being earlier (e.g., occurring earlier in time than a historical measurement occasion corresponding to another CSI report 505) . The priority parameter f may be set to larger values for CSI reports 505 associated with an earliest historical measurement occasion being later (e.g., occurring later in time than a historical measurement occasion corresponding to another CSI report 505) . In some cases, the priority parameter f may be set to smaller values for the first CSI report 505-a, where the historical measurement occasions associated with the second CSI report 505-b may be a subset of the historical measurement occasions associated with the first CSI report 505-a. The priority parameter f may be set to larger values for the second CSI report 505-b, where the historical measurement occasions associated with the second CSI report 505-b may be a subset of the historical measurement occasions associated with the first CSI report 505-a.
Additionally, or alternatively, the priority levels of the CSI reports 505 may be based on the measurement type (e.g., L1-RSRPs, L1-SINRs, AoAs/AoDs, raw channel responses) or the RS type (e.g., SSBs, CSI-RSs, DMRSs) associated with the historical measurement occasions. In some examples, the UE 115 may use one or more methods to identify historical measurement occasions. For a CSI report 505 among the first and second CSI reports 505, historical measurement occasions, together with types of measurements, may be determined based on one or more factors (e.g., network signaling for a particular CSI report 505, or an AI/ML functionality or model associated with the particular CSI report 505, or a UE pre-reported status or preference for a particular CSI report 505 or an AI/ML functional or model associated with a particular CSI report 505) . The priority levels for a CSI report 505 may be based on a control
signal from the network entity that indicates a preference for the first CSI report 505-a or a first AI or ML model associated with the first CSI report 505-a (e.g., a first ML or AI model that is configured by the network or generate by the UE 115, an output of which may indicate the first CSI report 505-a having a higher preference level) . The CSI reports 505 may be based on a pre-reported preference at the UE 115 for the first CSI report 505-a or a first AI or ML model associated with the first CSI report 505-a. For example, the UE may pre-report a first CSI report 505 having a higher priority, or may indicate a pre-reporting status for a particular CSI report (e.g., a particular CSI report may have been pre-reported by the UE 115 or the UE 115 may have a preference toward pre-reporting a higher priority CSI report 505, among other examples) .
FIG. 6 shows an example of a process flow 600 that supports inter-CSI priorities for temporal beam prediction reports in accordance with one or more aspects of the present disclosure. In some examples, process flow 600 may implement aspects of, or be implemented by aspects of, the wireless communication system 100, the communication timeline 200, the communication timeline 201, the communication timeline 300, the communication timeline 400, or the communication timeline 500. For example, the process flow 600 may include a UE 115-a and a network entity 105-a, which may be examples of corresponding devices described with reference to FIGs. 1–5.
At 605, the UE 115-a may buffer a first set of one or more historical measurement results for the first CSI report and a second set of one or more historical measurement results for the second CSI report. The first predictive measurement may be based at least in part on the first set of one or more historical measurement results and the second predictive measurement may be based at least in part on the second set of one or more historical measurement results.
At 610, the UE 115-a may receive control signaling indicating a first predictive measurement associated with a first CSI report and a second predictive measurement associated with a second CSI report. As described in greater detail with reference to FIG. 2, the predictive measurements may correspond to predicted measurements for a future slot that occurs after the slot in which the first and second CSI reports are scheduled, or may refer to predictive measurements based on buffered historical measurement results, or any combination thereof. The first CSI report and the
second CSI report may be scheduled for processing or transmission during a first slot. In some cases, the first predictive measurement may correspond to a second slot that occurs after the first slot and the second predictive measurement may correspond to a third slot that occurs after the first slot.
Additionally, or alternatively, the UE 115-a may receive a control message (e.g., received via control signaling at 610, or received via separate control signaling) indicating a set of priority values corresponding to respective parameter values for CSI reporting (e.g., priority parameters f, such as f1, f2, f3, and f4, among other examples, as described in greater detail with reference to FIGs. 3–5) .
In some examples, the control message may also indicate a set of priority values corresponding to respective parameter values for a first set of one or more parameters associated with the first predictive measurement and a second set of one or more parameters associated with the second predictive measurement. The parameters associated with the predictive measurements may corresponding to aspects of the predictive measurements based on which a priority level can be obtained. For instance, the first set of parameters may include a first content of the first CSI report and the second set of parameters may include a second content of the second CSI report, as described with reference to FIG. 3. The first set of parameters may include a timing of a second slot corresponding to the first predictive measurement and the second set of parameters may include a timing of a third slot corresponding to the second predictive measurement, as described with reference to FIG. 4. The first set of parameters may include one or more received RSs corresponding to the first predictive measurement, and the second set of parameters may include one or more virtual resources corresponding to the second predictive measurement, as described with reference to FIG. 4. The first set of parameters may include a first timing associated with an earliest historical measurement result for the first predictive measurement, and the second set of parameters may include an earliest historical measurement result for the second predictive measurement, as described with reference to FIG. 5. The first set of parameters and the second set of parameters may include an indication that the first priority level of the first CSI report is higher than the second priority level of the second CSI report, as described with reference to FIG. 5. The first set of parameters may include a pre-reporting status of the first CSI report, and the second set of parameters
may include an absence of a pre-reporting status for the second CSI report, as described with reference to FIG. 5.
At 615, the UE 115-a may obtain a first priority level according to one or more first priority values of the set of priority values corresponding to the first set of one or more parameters.
At 620, the UE 115-a may obtain a second priority level according to one or more second priority values of the set of priority values corresponding to the second set of one or more parameters.
In some cases, the UE 115-a may obtain the first priority level based at least in part on the first set of one or more parameters including first content of the first CSI report. The UE 115-a may obtain the second priority level based at least in part on the second set of one or more parameters including second content of the second CSI report. The first priority level may be higher than the second priority level based at least in part on the first content of the first CSI report corresponding to a higher priority than the second content of the second CSI report, as described in greater detail with reference to FIG. 3.
In some cases, the UE 115-a may obtain the first priority level based at least in part on the first set of one or more parameters including a timing of the second slot with reference to the first slot. The UE 115-a may obtain the second priority level based at least in part on the second set of one or more parameters including a timing and the third slot with reference to the first slot. The first priority level may be higher than the second priority level based at least in part on the second slot occurring before the third slot, as described in greater detail with reference to FIG. 4.
In some cases, the UE 115-a may obtain the first priority level based at least in part on the first set of one or more parameters including one or more received RSs corresponding to the first predictive measurement. The UE 115-a may obtain the second priority level based at least in part on the second set of one or more parameters including one or more virtual resources corresponding to the second predictive measurement. The first priority level may be higher than the second priority level based at least in part on the received RSs having a higher priority than the one or more virtual resources, as described in greater detail with reference to FIG. 4.
In some cases, the UE 115-a may obtain the first priority level based at least in part on the first set of one or more parameters including a first timing associated with an earliest historical measurement result in the first set of one or more historical measurement results. The UE 115-a may obtain the second priority level based at least in part on the second set of one or more parameters including a second timing associated with an earliest historical measurement result in the second set of one or more historical measurement results. The first priority level is higher than the second priority level based at least in part on the earliest historical measurement result in the first set of one or more historical measurement results occurring before the earliest historical measurement result in the second set of one or more historical measurement results, as described in greater detail with reference to FIG. 5.
In some cases, the UE 115-a may receive a control message indicating that the first priority level of the first CSI report is higher than the second priority level of the second CSI report.
In some cases, the UE 115-a may obtain the first priority level based at least in part on a pre-reporting status of the first CSI report. The first priority level may be higher than the second priority level based at least in part on an absence of the pre-reporting status for the second CSI report
At 625, the UE 115 may transmit or process the first CSI report during the first slot based at least in part on the first priority level associated with the first CSI report. The first priority level may be based at least in part on the first set of one or more parameters corresponding to the first predictive measurement.
At 630, the UE 115 may drop the second CSI report based at least in part on the second priority level associated with the second CSI report. Dropping the second CSI report may include refraining from transmitting the second CSI report, or refraining from processing the second CSI report, refraining from generating a completed CSI report, dropping or refraining from generating a set of report quantities for the second CSI report, wiping a buffer associated with the second CSI report, among other examples. The second priority level may be based at least in part on the second set of one or more parameters corresponding to the second predictive measurement, the first priority level having a higher priority than the second priority level.
FIG. 7 shows a block diagram 700 of a device 705 that supports inter-CSI priorities for temporal beam prediction reports in accordance with one or more aspects of the present disclosure. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. The device 705, or one or more components of the device 705 (e.g., the receiver 710, the transmitter 715, the communications manager 720) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
The receiver 710 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to inter-CSI priorities for temporal beam prediction reports) . Information may be passed on to other components of the device 705. The receiver 710 may utilize a single antenna or a set of multiple antennas.
The transmitter 715 may provide a means for transmitting signals generated by other components of the device 705. For example, the transmitter 715 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to inter-CSI priorities for temporal beam prediction reports) . In some examples, the transmitter 715 may be co-located with a receiver 710 in a transceiver module. The transmitter 715 may utilize a single antenna or a set of multiple antennas.
The communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be examples of means for performing various aspects of inter-CSI priorities for temporal beam prediction reports as described herein. For example, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
In some examples, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) . The hardware may include at least one of a processor, a digital signal processor (DSP) , a central processing unit (CPU) , a graphics processing unit (GPU) , an application-specific integrated circuit (ASIC) , a field-programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure. In some examples, at least one processor and at least one memory coupled with the at least one processor may be configured to perform one or more of the functions described herein (e.g., by one or more processors, individually or collectively, executing instructions stored in the at least one memory) .
Additionally, or alternatively, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in code (e.g., as communications management software) executed by at least one processor (e.g., referred to as a processor-executable code) .

Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, phase change memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) , or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc,
as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD) , floppy disk, and Blu-ray disc. Disks may reproduce data magnetically, and discs may reproduce data optically using lasers. Combinations of the above are also included within the scope of computer-readable media. Any functions or operations described herein as being capable of being performed by a memory may be performed by multiple memories that, individually or collectively, are capable of performing the described functions or operations.
As used herein, including in the claims, “or” as used in a list of items (e.g., including a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ” As used herein, the term “and/or, ” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items can be employed. For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “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” or “identify” or “identifying” encompasses a variety of actions and, therefore, “determining” or “identifying” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure) , ascertaining and the like. Also, “determining” or “identifying” can include receiving (such as receiving information or signaling, e.g., receiving information or signaling for determining, receiving information or signaling for identifying) , accessing (such as accessing data in a memory , or accessing information) and the like. Also, “determining” or “identifying” can include resolving, obtaining, selecting, choosing, establishing and other such similar actions.
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.
