[0001] FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications at a user equipment (UE) , including payload reinterpretation for overhead reduction of temporal beam prediction reports.BACKGROUND
[0003] 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) .

[0043] In wireless communications, a wireless device, such as a user equipment (UE) may report beam identifiers for one or more time domain (TD) occasions, including measured and predicted information. However, some approaches may involve reporting beam identifiers on a TD occasion-specific basis, which may involve additional overhead that may increase (e.g., linearly) as beam identifiers are reported for greater quantities of TD occasions. Such increasing overhead may be wasteful, particularly in situations in which different TD occasions have similar characteristics and substantially similar information may be reported for both and differentiation between them may involve the use of identifiers. Other approaches may involve beam identifier reporting on TD occasion-common basis, in a single or a reduced set of beam identifiers may be reported for multiple or all TD occasions. However, in situations in which conditions may vary widely between TD occasions, some information may be missed or not reported and throughput performance may be degraded. Thus, some approaches may be better suited for some situations, while other approaches may be better suited for other situations. However, current approaches may not allow for interoperability between these two approaches, resulting in reduced communication quality, reduced throughput, reduced resource utilization, increased overhead, and increased latency.
[0044] The techniques described herein include techniques for a UE to operate using either TD occasion-specific reporting of beam identifiers or TD occasion-common reporting of beam identifiers. Signaling between the UE and one or more network entities may allow the UE to coordinate operation using these different reporting techniques. For example, the UE may measure one or more resources to provide beam identifiers or other channel quality characteristics for one or more TD occasions associated with the one or more resources. To support coordination of multiple techniques (or for other purposes) , the UE may indicate in a report whether reporting payloads should be interpreted as being TD occasion-specific or TD occasion-common. Further, the UE may indicate in a report whether TD occasion-specific reporting is valid, reliable, or meaningful for a nearest TD occasion, multiple TD occasions, or all TD occasions associated with the report. Further, such reporting of channel quality characteristic values may include differential values relative to a reference absolute channel quality characteristic value (e.g., a strongest value or a first-in-time value) . In at least these ways, communications quality throughout, resource utilization, flexibility, and reliability may be increased while reducing overhead and latency.
[0045] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are then described with reference to an occasion-specific scheme, an occasion-common scheme, reporting schemes, 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 payload reinterpretation for overhead reduction of temporal beam prediction reports.
[0046] FIG. 1 shows an example of a wireless communications system 100 that supports payload reinterpretation for overhead reduction of temporal beam prediction reports in accordance with one or more examples as disclosed herein. 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.
[0047] 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) .
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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) .
[0052] 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) ) .
[0053] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0054] 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.
[0055] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor) , IAB node (s) 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130) . That is, an IAB donor may refer to a RAN node with a wired or wireless connection to the core network 130. The IAB donor may include one or more of a CU 160, a DU 165, and an RU 170, in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . The IAB donor and IAB node (s) 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol) . Additionally, or alternatively, the CU 160 may communicate with the core network 130 via an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs (e.g., including a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of another portion of a backhaul link.
[0056] IAB node (s) 104 may refer to RAN nodes that provide IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities) . A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node (s) 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with IAB node (s) 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through other IAB node (s) 104) . Additionally, or alternatively, IAB node (s) 104 may also be referred to as parent nodes or child nodes to other IAB node (s) 104, depending on the relay chain or configuration of the AN. The IAB-MT entity of IAB node (s) 104 may provide a Uu interface for a child IAB node (e.g., the IAB node (s) 104) to receive signaling from a parent IAB node (e.g., the IAB node (s) 104) , and a DU interface (e.g., a DU 165) may provide a Uu interface for a parent IAB node to signal to a child IAB node or UE 115.
[0057] For example, IAB node (s) 104 may be referred to as parent nodes that support communications for child IAB nodes, or may be referred to as child IAB nodes associated with IAB donors, or both. An IAB donor may include a CU 160 with a wired or wireless connection (e.g., backhaul communication link (s) 120) to the core network 130 and may act as a parent node to IAB node (s) 104. For example, the DU 165 of an IAB donor may relay transmissions to UEs 115 through IAB node (s) 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment via an F1 interface to IAB node (s) 104, and the IAB node (s) 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through one or more DUs (e.g., DUs 165) . That is, data may be relayed to and from IAB node (s) 104 via signaling via an NR Uu interface to MT of IAB node (s) 104 (e.g., other IAB node (s) ) . Communications with IAB node (s) 104 may be scheduled by a DU 165 of the IAB donor or of IAB node (s) 104.
[0058] 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) .
[0059] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0060] 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.
[0061] 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) .
[0062] In some examples, such as in a carrier aggregation configuration, a carrier may have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different RAT) .
[0063] The communication link (s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0064] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0065] 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.
[0066] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
[0067] 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) .
[0068] 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.
[0069] 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) ) .
[0070] 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) .
[0071] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) ) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0072] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a network entity 105 operating with lower power (e.g., a base station 140 operating with lower power) relative to a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network entity 105 may support one or more cells and may also support communications via the one or more cells using one or multiple component carriers.
[0073] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[0074] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0075] The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base stations 140) may have similar frame timings, and transmissions from different network entities (e.g., different ones of the network entities 105) may be approximately aligned in time. For asynchronous operation, network entities 105 may have different frame timings, and transmissions from different network entities (e.g., different ones of network entities 105) may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.
[0076] Some UEs 115, such as MTC or IoT devices, may be relatively low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity 105 (e.g., a base station 140) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.
[0077] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 may include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.
[0078] 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.
[0079] 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.
[0080] In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., network entities 105, base stations 140, RUs 170) using vehicle-to-network (V2N) communications, or with both.
[0081] 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.
[0082] 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.
[0083] The wireless communications system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz, also known as the centimeter band, or using an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) , also known as the millimeter band. In some examples, the wireless communications system 100 may support millimeter wave (mmW) communications between the UEs 115 and the network entities 105 (e.g., base stations 140, RUs 170) , and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, such techniques may facilitate using antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.
[0084] 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.
[0085] 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.
[0086] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0087] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0088] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0089] 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.
[0090] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0091] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0092] The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0093] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link (s) 125, a D2D communication link 135) . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0094] In some implementations, a UE 115 and a network entity 1t05 may support one or more mechanisms according to which the UE 115 and the network entity 105 may report predicted beam identifiers based on measured information, predicted information, or both. For example, a UE may measure one or more reference signals in response to receiving control signaling that the UE is to provide a measurement report for one or more resources. The UE may then prepare the measurement report, which may indicate one or more beam identifiers. In some examples, the UE may indicate in the report whether the reporting payloads (e.g., including one or more measurements (e.g., measured or predicted measurements) associated with one or more TD occasions are to be interpreted on an occasion-specific basis or an occasion-common basis. In some examples, the UE may indicate in the report whether beam identifiers are reliable for a single TD occasion, multiple TD occasions, or all TD occasions associated with the reporting. In some examples, the UE may indicate the measurements in a differential manner with respect to an absolute measurement, which may be a strongest measurement or a first-in-time or first-indexed measurement.
[0095] FIG. 2 shows an example of an occasion-specific scheme 201 and an occasion-common scheme 202 that support payload reinterpretation for overhead reduction of temporal beam prediction reports in accordance with one or more examples as disclosed herein.
[0096] In the occasion-specific scheme 201, one or more selected beam IDs 235-a may be selected for the TD occasion 220-a, the TD occasion 220-b, the TD occasion 220-c, and the TD occasion 220-d, from each of the beam IDs 230-a, beam IDs 230-b, the beam IDs 230-c, and the beam IDs 230-d. In some examples, the beam IDs 230-a, beam IDs 230-b, the beam IDs 230-c, and the beam IDs 230-d may be different beams, have one or more common beams, or may all be common beams. In some examples, the measurements 225-a may be associated with the TD occasion 220-a, the measurements 225-b may be associated with the TD occasion 220-b, the measurements 225-c may be associated with the TD occasion 220-c, and the measurements 225-d may be associated with the TD occasion 220-d.
[0097] In the occasion-common scheme 202, one or more selected beam IDs 235-b may be selected for the TD occasion 220-e, the TD occasion 220-f, the TD occasion 220-g, and the TD occasion 220-h, from the beam IDs 230-e. In some examples, the measurements 225-e may be associated with the TD occasion 220-e, the measurements 225-f may be associated with the TD occasion 220-f, the measurements 225-g may be associated with the TD occasion 220-g, and the measurements 225-h may be associated with the TD occasion 220-h.
[0098] The techniques described herein, including the occasion-specific scheme 201 and the occasion-common scheme 202 generally relate to the management of downlink transmission beam prediction, which may be applicable to both UE side models and network side models. For example, the techniques described herein may involve spatial-domain downlink transmission beam prediction for a set of beams based on the measurement results of another set of beams. Additionally, or alternatively, the techniques described herein may involve temporal downlink transmission beam prediction for a set of beams based on the historical measurement results of another set of beams. Further, the techniques described herein may involve related signaling or mechanisms to facilitate Link Control Management (LCM) operations that are specific to the beam management use cases, if any exist. Additionally, or alternatively, common frameworks may be employed to accommodate multiple techniques described herein.
[0099] For example, the techniques described herein may relate to UE-side artificial intelligence (AI) or machine learning (ML) models. For example, the UE may signal (e.g., via L1 signaling) information associated with AI or ML model inferences related to the beam (s) of a quantity of future time domain instances. Further, the UE may signal information associated with AI or ML model inferences associated with time domain stamp information corresponding to the reported beam.
[0100] The occasion-specific scheme 201 may involve the reporting (e.g., in an L1 report) of the selected beam IDs 235-a from the beam IDs 230 for respective TD occasions 220 in a single report. The measurements 225 associated with a TD occasion of the occasion-specific beam IDs 230 (e.g., the selected beam IDs 235) may be reported sequentially (or in another manner) to the network entity. By employing such techniques, no information is missing at the network entity receiving the report. However, the overhead for reporting beam identifiers increases linearly with the quantity of TD occasions. This could potentially be wasteful if different temporal occasions are differentiated from each other by the ordering of the beams while the top beam identifiers remain the same.
[0101] The occasion-common scheme 202 involves reporting a single set of selected beam IDs 235-b in a report (e.g., an L1 report) , which are commonly applied to multiple TD occasions 220 or all TD occasions 220 in the same report. In some examples, the intervals between TD occasions 220 may be 10 ms (e.g., or a multiple thereof) , but may occur at different time intervals. The criteria on how to choose the selected beam IDs 235-b may be predefined, controlled or signaled by a network entity, or UE-determined and UE-reported to the network entity. The measurements 225 associated with the selected beam IDs 235-b may be reported sequentially (or in another manner) . However, such measurements 225 may be associated with different TD occasions 220. For example, the measurements 225-e may be associated with the TD occasion 220-e, the measurements 225-f may be associated with the TD occasion 220-f, the measurements 225-g may be associated with the TD occasion 220-g, and the measurements 225-h may be associated with the TD occasion 220-h. By employing the occasion-common scheme 202, the overhead for beam ID 230 reporting is well controlled (e.g., assuming that top beam identifiers do not vary across TD occasions 220 (e.g., at a walking speed) . However, in situations in which top beam IDs 230 across TD occasions 220 are actually varying (e.g., switching from one SSB towards another SSB) , detailed information could potentially be missing and throughput performance may be degraded.
[0102] FIG. 3 shows an example of a reporting scheme 301 and a reporting scheme 302 that support payload reinterpretation for overhead reduction of temporal beam prediction reports in accordance with one or more examples as disclosed herein.
[0103] Given the differing characteristics of the occasion-specific scheme 201 and the occasion-common scheme 202, it may be desirable to define techniques for operating under the occasion-specific scheme 201 and the occasion-common scheme 202 under different circumstances. For example, it may be desirable to employ a single report (e.g., an L1 report, such as the report 320) that could be adaptable for both the occasion-specific scheme 201 and the occasion-common scheme 202. In some examples, such a report could be based on a 1-part channel state information (CSI) report. Such a report may be adaptively altered for use between the occasion-specific scheme 201 and the occasion-common scheme 202. Further, it may also be desirable to reduce overhead associated with reporting.
[0104] Thus, a reporting indication 325 may be included in the report 320 for both the reporting scheme 301 and the reporting scheme 302. The reporting indication 325 may be a single bit or multiple bits for the reinterpretation of the reporting payload 335.
[0105] In the reporting scheme 301, a single additional bit may be included in the reporting indication 325-a. This bit would indicate whether the remaining reporting payload 335-a (or multiple such remaining reporting payloads 335-a) are to be interpreted based on the occasion-specific scheme 201 or the occasion-common scheme 202. In some examples, to maintain the same payload size, and considering that occasion-specific scheme 201 may consume a greater quantity of bits to report beam IDs, the quantity of TD occasions, the quantity of beams, measurement (e.g., L1-RSRP / SINR) quantization bit-widths, or any combination thereof could differ between occasion-specific scheme 201 and occasion-common scheme 202.
[0106] The reporting scheme 302 includes a reporting indication 325-b to be used in association with the occasion-common scheme 202. The reporting indication 325-b may include a single-bit or multiple bits that indicate whether the selected beam IDs 350 (e.g., selected from the beam IDs 340-a or the beam IDs 340-b) are meaningful or reliable for the nearest TD occasion 345 but are not reliable for later occasions (e.g., as depicted in association with the reliability indication 350-a for the TD occasion 345-a, the TD occasion 345-b, the TD occasion 345-c, and the TD occasion 345-d) , or if they are reliable across multiple or all TD occasions 345 associated with the report (e.g., as depicted in association with the reliability indication 350-b for the TD occasion 345-e, the TD occasion 345-f, the TD occasion 345-g, and the TD occasion 345-h) . If the former is true, the measurements associated with the later occasions may also be unreliable. In either case, if the information is not interpreted in accordance with the occasion-common scheme 202, the network may additionally schedule more reports to retrieve the missing information that is not included in the report 320.
[0107] In the reporting scheme 301, the reporting scheme 302, or both, the network entity may request that the UE transmit channel quality characteristics associated with one or more resources regarding a quantity (e.g., a quantity N) of TD occasions (e.g., the TD occasions 345) , via a single report (e.g., the report 320) , such as a CSI report. These TD occasions 345 could be occasions occurring earlier or later in time than the indicated resources associated with the report 320 or earlier or later than the slot associated with transmission of the report 320 associated with the CSI report. Such reporting may be applicable to temporal beam prediction, reporting historical measurements, or both.
[0108] The channel quality characteristics may include predicted or measured metrics, such as RSRP (e.g., L1-RSRP) , SINR (e.g., L1-SINR) , one or more other metrics or measurements, or any combination thereof. Such channel quality characteristics may be reported with one or more resources identifiers of the one or more resources to be monitored, predicted top-K resources in terms of the channel quality characteristics (e.g., L1-RSRP / L1-SINR) , predicted top-K resources in terms of probabilities of being the top-1 or top-K resources with respect to the channel quality characteristics (e.g., L1-RSRP / L1-SINR) , measured top-K resources in terms of the channel quality characteristics (e.g., L1-RSRP / L1-SINR) , or any combination thereof.
[0109] In scenarios involving actual measurements, the resources associated with such reporting may be synchronization signal block (SSB) resources, CSI-RS resources, one or more other resources, or any combination thereof. In scenarios involving predicted measurements, the resources may be virtual SSB resources, virtual CSI-RS resources, one or more other virtual resources, or any combination thereof. In some examples, the payload size of the reporting payload 335 may be fixed. In some examples, such a payload size may be based on a 1-part reporting framework, such as a 1-part CSI reporting framework. In some examples, the reporting indication 325 may be included in the reporting payload 335 or may be separate from the reporting payload 335.
[0110] In the reporting scheme 301, a single-bit payload reinterpretation for the report 320 with respect to multiple TD occasions may be employed. For example, the reporting indication 325-a may include a single bit in a field (e.g., a CSI field, such as a first CSI field) . In the reporting scheme 301, such a single bit may indicate whether the remaining reporting payload 335-a is to be interpreted based on the occasion-specific scheme 201 or the occasion-common scheme 202.
[0111] In some examples, the criteria for a UE to determine when and how to transition between occasion-specific scheme 201 and occasion-common scheme 202 (e.g., at the scheme determination 330) and report the reporting indication 325-a in the report may be predefined, signaled to the UE by a network entity, determined by the UE, reported to the network entity, or any combination thereof. In some examples, in cases of multiple predefined criteria, multiple candidate criteria or parameter sets associated with the criteria may be considered. For example, the network entity may signal one or more candidate criteria or parameter sets associated with the criteria via signaling, such as CSI report setting signaling, MAC-CE signaling, activation of semi-persistent (SP) CSI reports, an aperiodic (AP) CSI report, other signaling, or any combination thereof. In some examples, this signaling may be based on down-selecting from predefined options. In some examples in which the UE selects such criteria, the UE may report the selected criteria via UE capability reporting or including one or more indications of such criteria in the report 320. This reporting may be based on down-selecting from standard predefined options or network signaled options.
[0112] In some examples, if there exists a quantity of TD occasions that is greater than a threshold quantity (e.g., N’ TD occasions) where the one or more strongest (e.g., Top-K’) resources identified in the quantity of TD occasions associated with the occasion-specific scheme 201 are different from the strongest (e.g., Top-K’) resources considered in association with the occasion-common scheme 202, the UE may switch operation to the occasion-specific scheme 201. Otherwise, the UE may operate in accordance with the occasion-common scheme 202. In some examples, the value K’ may be less than or equal to K and the value N’ may be less than or equal to N, where N indicates a quantity of TD occasions associated with the reporting and K indicates a quantity of resources associated with the reporting. N’ and K’ may be predefined, signaled to the UE by a network entity, determined and reported by the UE, or any combination thereof.
[0113] In some examples, the difference between Top-1 resources determined in association with the occasion-specific scheme 201 and those determined in association with the occasion-common scheme 202 result in least a degradation in channel quality characteristic (e.g., RSRP, SINR, or other characteristics) represented by a value of X. In some examples, the value of X may be predefined, signaled to the UE by a network entity, determined and reported by the UE, or any combination thereof.
[0114] In some examples, the quantity of TD occasions, the quantity of resources to be captured per TD occasion, the quantity of bits to be used to carry one or more channel quality characteristics, or any combination thereof, may be smaller for the occasion-specific scheme 201 as compared to occasion-common scheme 202. In some cases in which the quantity of TD occasions is to be reduced in the occasion-specific scheme 201, one or more nearest TD occasions (e.g., those nearest in time to the resources associated with the reporting or with transmitting the report 320) may be prioritized and other TD occasions may not be considered for the reporting. In some examples, the quantity of resources to be captured per TD occasion, the quantity of bits to be used to carry one or more channel quality characteristics, or any combination thereof for the occasion-specific scheme 201, the occasion-common scheme 202, or both, may be predefined, signaled to the UE by a network entity, determined and reported by the UE, or any combination thereof.
[0115] In some examples, the occasion-specific scheme 201 may be associated with a quantity K1 of beams, a quantity N1 of TD occasions, and related channel quality characteristics (e.g., measurements, such as RSRP, SINR, or other measurements, be they actual or predicted) . In some examples, the occasion-specific scheme 201 may be associated with a quantity of A1 / D1 bits used to quantize one or more channel quality characteristics (e.g., RSRP, SINR, or other measurements, be they actual or predicted) .
[0116] In some examples, the occasion-common scheme 202 may be associated with a quantity K2 of beams, a quantity N2 of TD occasions, and related channel quality characteristics (e.g., measurements, such as RSRP, SINR, or other measurements, be they actual or predicted) . In some examples, the occasion-common scheme 202 may be associated with a quantity of A2 / D2 bits used to quantize one or more channel quality characteristics (e.g., RSRP, SINR, or other measurements, be they actual or predicted) . In some examples, K1 may be less than or equal to K2, N1 may be less than or equal to N2, A1 may be less than or equal to A2, and D1 may be less than or equal to D2.
[0117] In the reporting scheme 302, assuming that the reporting payload 335-b is to be interpreted in accordance with the occasion-common scheme 202, the single-bit (or multiple bits) may indicate whether the selected beam IDs 350 are reliable for a single TD occasion 345 (e.g., a nearest in time TD occasion 345 to the transmission of the report 320 or the resources that the UE monitors) but are not reliable for later occasions (e.g., in accordance with the reliability indication 350-a) , or if the selected beam IDs 350 are reliable across multiple TD occasions 345 or all TD occasions 345 associated with the report 320. In some examples, the reliability indication 350-a, the reliability indication 350-b, or both, may be included in the reporting indication 325-b, the reporting payload 335-b, or another portion of the report 320.
[0118] In some examples, the criteria for a UE to determine when and how to transition between reporting the reliability indication 350-a (e.g., indicating that the selected beam IDs 350 are reliable for a single TD occasion 345 or a quantity of TD occasions 345 (e.g., 1, 2 or 3) that is less than the total quantity of TD occasions 345 (e.g., 4) ) and reporting the reliability indication 350-b (e.g., indicating that the selected beam IDs 350 are reliable for all of the TD occasions 345 associated with the report 320) may be predefined, signaled to the UE by a network entity, determined by the UE, reported to the network entity, or any combination thereof. In some examples, in cases of multiple predefined criteria, multiple candidate criteria or parameter sets associated with the criteria may be considered. For example, the network entity may signal one or more candidate criteria or parameter sets associated with the criteria via signaling, such as CSI report setting signaling, MAC-CE signaling, activation of SP CSI reports, an AP CSI report, other signaling, or any combination thereof. In some examples, this signaling may be based on down-selecting from predefined options. In some examples in which the UE selects such criteria, the UE may report the selected criteria via UE capability reporting or including one or more indications of such criteria in the report 320. This reporting may be based on down-selecting from standard predefined options or network signaled options.
[0119] In some examples, if there exists a quantity of TD occasions 345 that is greater than a threshold quantity (e.g., expressed as N’ TD occasions) where the one or more strongest (e.g., Top-K’) resources identified in the quantity of TD occasion 345 associated with reporting the reliability indication 350-a (e.g., for one TD occasion 345, such as a nearest TD occasion 345) are different from the strongest (e.g., Top-K’) resources considered in association with reporting the reliability indication 350-b (e.g., for all of the TD occasions 345 associated with the reporting) , the UE may report the reliability indication 350-a. Otherwise, the UE may report the reliability indication 350-b. In some examples, the value K’ may be less than or equal to K and the value N’ may be less than or equal to N, where N indicates a quantity of TD occasions 345 associated with the reporting and K indicates a quantity of resources associated with the reporting. N’ and K’ may be predefined, signaled to the UE by a network entity, determined and reported by the UE, or any combination thereof.
[0120] In some examples, the difference between strongest (e.g., top-1) resource determined in association with reporting the reliability indication 350-a and those determined in association with reporting the reliability indication 350-b may result in least a degradation in channel quality characteristic (e.g., RSRP, SINR, or other characteristics) represented by a value of X dB. In some examples, the value of X may be predefined, signaled to the UE by a network entity, determined and reported by the UE, or any combination thereof. For example, the difference on a Top-1 resource may lead to at least X-dB measured / predicted L1-RSRP / L1-SINR degradation.
[0121] In some examples in which a single TD occasion 345 associated with the reporting is considered or indicated as reliable, it may be that measurements associated with later TD occasions 345 (e.g., those occurring later in time than the single TD occasion 345 indicated as reliable) may not be reliable. As such, in some examples, the payloads of the reporting payload 335-b originally occupied by or associated with the “unreliable” TD occasions 345 may be reinterpreted or reused for other purposes. For example, such payloads could indicate a desired AP CSI report setting identifier, an SP CSI report setting identifier, an AP triggering-state identifier, a MAC-CE identifier, other information, or any combination thereof, for reporting the missing information from the current CSI report due to only indicating a single TD occasion 345 (or a quantity of TD occasions 345 that is less than the total quantity of TD occasions 345) . Additionally, or alternatively, such payloads could be used to indicate the values of K’, N’, or both as described herein.
[0122] In some examples, the reporting scheme 302 may also involve the use of multiple bits in the reporting indication 325-b. For example, in such a scheme, each bit-point may indicate that the top-K” resource identifiers are reliable (e.g., up to the closest N” TD occasions) . The candidates for K” and N” (e.g., where K” is less than or equal to K and N” is less than or equal to N) may be predefined, signaled to the UE by a network entity, determined and reported by the UE, or any combination thereof.
[0123] In some examples, fields in the reporting payload 335-b for reporting channel quality characteristics (e.g., measurements) that would otherwise be associated with unreliable TD occasions 345 (were such TD occasions 345 reliable) , such fields may be reported with minimal information or may be repurposed to include other information (e.g., information described herein in other payload repurposing techniques) .
[0124] For example, given that the UE is operating in accordance with the occasion-common scheme 202 and further given N=4 TD occasions 345 and top-K=4 beams, various options for reporting may be employed. In a first example in which 2 bits are used, N” may be {1, 2, 3, 4} , allowing the user equipment to signal up to the {1st, 2nd, 3rd, 4th} TD occasion 345. All the occasion-common Top-4 beams reported in the payload are indicated as reliable, but may not be indicated as reliable for other remaining TD occasions 345. In a second example in which 3 bits are used, K” may be 1, such that the additional 1 bit for reporting (e.g., as compared to the first example) may be used to signal information associated with the “reliable” TD occasions 345, such as indicating whether only the top-1 beam is reliable or all top-4 beams are reliable. For the remaining “non-reliable” TD occasions 345 indicated as in the first example, all top-4 beams are considered to be not reliable. In a third example, in which 4 bits are used, K” may be {1, 2, 3, 4} , such that the additional 2 bits (e.g., as compared to the first option) may be used to signal information associated with the “reliable” TD occasions 345, indicating that the reliable top beams are the top-1 beams, top-2 beams, top-3 beams, or top-4 beams. For the remaining “non-reliable” TD occasions 345 indicated as in the first example, all top-4 beams are considered to be not reliable.
[0125] In some examples associated with the reporting scheme 302, a predefined field (e.g., a CSI field) in the report 320 (e.g., a first field following the reporting indication 325-b) may be utilized to report a TD occasion 345 of the strongest resource or resources (or associated identifiers) . For example, the channel quality characteristics associated with the {resource identifier, TD occasion 345 identifier} pair may be reported via quantization (e.g., absolute L1-RSRP / SINR quantization) , and the channel quality characteristics of the remaining {resource identifier, TD occasion 345 identifier} pairs may be reported differentially (e.g., via negative dB values) with reference to the strongest channel quality characteristic (e.g., a n L1-RSRP or L1-SINR) that is an absolute measurement or value. In some examples, the strongest resource or resource identifier may be reported first among all resources associated with the reporting. In some examples, a quantity of bits used for such a field may be based on a quantity of TD occasion 345 considered. For instance, if four TD occasions 345 are considered, such a field may be 2 bits.
[0126] Additionally, or alternatively, in the absence of such a field, the channel quality characteristic (e.g., L1-RSRP or L1-SINR) for a predefined resource identifier in a predefined TD occasion 345 (e.g., a first resource associated with the first TD occasion 345) may be absolutely quantized and reported, while all remaining channel quality characteristics (e.g., L1-RSRPs or L1-SINRs) may be differentially quantized with reference to this channel quality characteristic. Such techniques may involve both negative and positive dB values for the differential channel quality characteristics’ quantization bit-points. In some examples, such a differential reporting scheme may be employed independently or in conjunction with one or more other techniques described herein.
[0127] In some examples, it may be assumed that channel quality characteristics are not to be included in the report 320 or not included for one or more TD occasions 345. In some examples, all the reported information may pertain to future TD occasions 345 occurring later-in-time than the reference resource (e.g., a CSI reference resource) or a slot carrying the report 320. In some such cases, predicted Top-K-resource identifiers may be reported (e.g., without corresponding channel quality characteristics) .
[0128] For example, a first TD occasion 345 may pertain to historical measurements or channel quality characteristics before the reference resource or before the slot carrying the report 320, while remaining TD occasions 345 may be associated with future or predicted measurements or channel quality characteristics. In such cases, it may be that measured channel quality characteristics for the first TD occasion 345 are carried while channel quality characteristics associated with the remaining TD occasions 345 may not be captured. Additionally, or alternatively, multiple quantities of channel quality characteristics or measurements associated with closer TD occasions 345 may be captured, while remaining channel quality characteristics or measurements associated with later TD occasions 345 are not. In some examples, other techniques described herein may be extended by removing applicable channel quality characteristics in the respective methods.

[0241] It should be noted that the methods described herein describe possible implementations. The operations and the steps may be rearranged or otherwise modified and other implementations are possible. Further, aspects from two or more of the methods may be combined.
[0242] Although aspects of an LTE, LTE-A, LTE-A Pro, or NR system may be described for purposes of example, and LTE, LTE-A, LTE-A Pro, or NR terminology may be used in much of the description, the techniques described herein are applicable beyond LTE, LTE-A, LTE-A Pro, or NR networks. For example, the described techniques may be applicable to various other wireless communications systems such as Ultra Mobile Broadband (UMB) , Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20, Flash-OFDM, as well as other systems and radio technologies not explicitly mentioned herein.
[0243] Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0244] The various illustrative blocks and components described in connection with the disclosure herein may be implemented or performed using a general-purpose processor, a DSP, an ASIC, a CPU, a graphics processing unit (GPU) , a neural processing unit (NPU) , an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.
[0245] The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. 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.
[0246] 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, 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.
[0247] As used herein, including in the claims, “or” as used in a list of items (e.g., 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. ”
[0248] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0249] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure) , ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) , and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0250] 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.
[0251] 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.
[0252] 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.
