Description

TECHNIQUES FOR AUTONOMOUS TIME DOMAIN BEAM PREDICTION

FIELD OF TECHNOLOGY

The following relates to method for wireless communication, including techniques for autonomous time domain beam prediction.

BACKGROUND

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) .

A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) . A UE and a network entity may participate in a beam sweeping procedure to identify a beam for communications. In some examples, a UE may perform one or more beam measurements and transmit the measurement report to the network entity. Techniques for beam measurements may be enhanced.

DETAILED DESCRIPTION

Some wireless communications systems may support wireless communications between network nodes, such as a user equipment (UE) (e.g., a first network node) and a network entity (e.g., a second network node) . For example, a network entity may transmit reference signals to the UE via one or more beams. In some aspects, the UE may measure a reference signal (such as a synchronization signal block or a channel state information reference signal) in order to determine which one or more beams may be best for communications between the UE and the network entity based on having a highest or strongest measurement. Accordingly, the network entity may transmit the reference signals on multiple different beams while relying on the UE to measure each of the beams and report one or more beams in a measurement. The UE may report the measurements in accordance with a channel state information report configuration indicated by the network entity. In some cases, the UE may perform autonomous beam prediction, where the UE may determine the beam or beams that are best for communications based on predicting one or more channel characteristics (e.g., reference signal received power) . Techniques depicted herein provide for a UE to indicate to the network entity, that it has the capability of predicting channel characteristics.

In some examples, the UE may indicate, to the network entity, a capability information indicating that the UE is capable of predicting one or more channel characteristics for autonomous beam prediction. For example, the UE may be scheduled with a channel state information report associated with a channel measurement resource set. In such cases, the UE may transmit capability information indicating that it is capable of predicting channel characteristics. The UE may also indicate a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles. The UE may determine the predicted future channel characteristics associated with a prediction cycle based on historical channel measurements associated with the channel measurement resource set. Additionally, or alternatively, the UE may determine the predicted future channel characteristics associated with a prediction cycle based on historically predicted future channel characteristics associated with other historical prediction cycles. In some examples, using control signaling, the UE may update the ratio between the contiguous number of measurement cycles and the contiguous number of prediction cycles based on observing a set of channel characteristics.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to 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 techniques for autonomous time domain beam prediction.

FIG. 1 illustrates an example of a wireless communications system 100 that supports techniques for autonomous time domain beam prediction in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more 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 one or more communication links 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 one or more communication links 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, such as other 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 the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 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 a backhaul communication link 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 a 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 links 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) , 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 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 a 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 a single network entity 105 (e.g., 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 two or more network entities 105, such as an integrated access 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) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (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) 180 system, 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 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, and 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 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 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 more RUs 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 one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 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 105 that are in communication via such communication links.

In wireless communications systems (e.g., 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 network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include 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 an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 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., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.

For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor) , IAB nodes 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 core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170) , in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . IAB donor and IAB nodes 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 via an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs 160 (e.g., a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.

An IAB node 104 may refer to a RAN node that provides 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 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with the IAB node 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 one or more other IAB nodes 104) . Additionally, or alternatively, an IAB node 104 may also be referred to as a parent node or a child node to other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of IAB nodes 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and the DU interface (e.g., DUs 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or UE 115.

For example, IAB node 104 may be referred to as a parent node that supports communications for a child IAB node, or referred to as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 with a wired or wireless connection (e.g., a backhaul communication link 120) to the core network 130 and may act as parent node to IAB nodes 104. For example, the DU 165 of IAB donor may relay transmissions to UEs 115 through IAB nodes 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of IAB donor may signal communication link establishment via an F1 interface to IAB nodes 104, and the IAB nodes 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through the DUs 165. That is, data may be relayed to and from IAB nodes 104 via signaling via an NR Uu interface to MT of the IAB node 104. Communications with IAB node 104 may be scheduled by a DU 165 of IAB donor and communications with IAB node 104 may be scheduled by DU 165 of IAB node 104.

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 techniques for autonomous time domain beam prediction 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., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .

A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.

The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act 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 one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical 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 105) .

In some examples, such as in a carrier aggregation configuration, a carrier may also 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 radio access technology) .

The communication links 125 shown in 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) .

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 radio access technology (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.

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.

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.

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 T_s=1/ (Δf_max·N_f) seconds, for which Δf_max may represent a supported subcarrier spacing, and N_f 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 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., N_f) 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 multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.

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) , or others) . 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.

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 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

Some UEs 115, such as MTC or IoT devices, may be 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.

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 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.

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 115 via a device-to-device (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 each of the other 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 100 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 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.

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) radio access technology, 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, 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.

Some signals, such as data signals associated with a particular receiving device, may be transmitted by transmitting device (e.g., a transmitting network entity 105, a transmitting UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as a receiving network entity 105 or a receiving 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 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) .

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 receiving 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) .

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.

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., a communication link 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 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.

In some aspects, wireless communications system 100 may support artificial intelligence or machine learning models for air-interface corresponding to each target use case regarding aspects such as performance, and complexity. Each target case may include beam management (e.g., beam prediction in time) , spatial domain for overhead and latency reduction, and beam selection accuracy improvement. The artificial intelligence or machine learning approaches for the selected use cases may be diverse to support various aspects on collaboration levels between the network entity 105 and the UE 115. The artificial intelligence or machine learning models may support identifying common and specific characteristics for framework investigations.

In some examples, the wireless communications system 100 may support techniques to characterize lifecycle management of artificial intelligence or machine learning models (e.g., model training, model deployment, model inference, model monitoring, model updating, etc. ) . In some examples, the UE 115 may be configured with multiple parameters for transmitting a channel state information report (e.g., ReportQuantity=ssb-Index-RSRP or ssb-Index-SINR or cri-RSRP or cri-SINR for joint synchronization signal block resource indicator or channel state information resource indicator and L1 reference signal received power or L1 signal interference to noise ratio in beam reporting. The UE 115 may report a number of reported resource signals noofReportedRS. In some examples, the UE 115 may be configured using an RRC signaling. The RRC signal may configure 2 or 4 reports depending on UE capability. Additionally, the RRC signal may configure different synchronization signal block resource indicator or channel state information resource indicator for each channel state information reporting configuration (e.g., CSI-ReportConfig) .

In some examples, the UE 115 may perform a set of beam measurements to determine a reference signal received power. The UE 115 may then report the reference signal received power to the network entity 105. In some cases, the UE 115 may report a beam having the strongest reference signal received power among all the beams that are measured by the UE 115. In some examples, for the strongest synchronization signal block resource indicator, the UE 115 may use 7-bits to report reference signal received power in the range of [-140, -44] dBm with 1dBm step size. For remaining synchronization signal block resource indicators or channel state information resource indicators, the UE 115 may use 4-bits to report a differential reference signal received power in the range of [0, -30] dB with 2dB step size and a reference to the strongest synchronization signal block resource indicator’s or channel state information resource indicator’s reference signal received power. For the synchronization signal block resource indicator’s or channel state information resource indicator’s reference signal received power, there may be invalid code-points considering 2⁷=128 where 140-44+1=97. In some examples, mapping between the reported 7-bits or 4-bits code-points and the actually measured reference signal received power values may be pre-defined.

In some examples, the UE 115 may report a signal interference to noise ratio. For the strongest synchronization signal block resource indicator or channel state information resource indicator, the UE 115 may use 7-bits to report the signal interference to noise ratio in the range of [-23, 40] dB with 0.5dB step size. For remaining synchronization signal block resource indicators or channel state information resource indicators, the UE 115 may use 4-bits to report a differential signal interference to noise ratio in the range of [0, -15] dB with 1 dB step size and a reference to the strongest synchronization signal block resource indicator’s or channel state information resource indicator’s L1 signal interference to noise ratio. For the strongest and the remaining synchronization signal block resource indicators or channel state information resource indicators, there are may not be any invalid code-points, but SINR_0 may stand for SINR<-23 dB for the strongest synchronization signal block resource indicator or channel state information resource indicator, while DIFFSINR_15 may stand for ΔSINR≤-15dB. In some cases, the mapping between the reported 7-bits or 4-bits code-points and the actually measured signal interference to noise ratio values may be pre-defined.

For artificial intelligence or machine learning-based beam management, the UE 115 and the network entity 05 may support beam management case 1 and beam management case 2 for characterization and baseline performance evaluations. In beam management case 1, the UE 115 may perform spatial-domain downlink beam prediction for Set A of beams based on measurement results of Set B of beams. For beam management case 2, the UE 115 may perform a temporal downlink beam prediction for Set A of beams based on the historic measurement results of Set B of beams. For beam management case 1 and beam management case 2, beams in Set A and Set B may be in the same frequency range. In some cases, for the sub use case beam management case 1, Set B may be a subset of Set A or Set A and Set B may be different (e.g., Set A includes narrow beams and Set B includes wide beams) . In some examples, Set A may be used for downlink beam prediction and Set B may be used for downlink beam measurement. For the sub use case beam management case 1, Set A and Set B may be different (Set B is not a subset of Set A) or Set B may be a subset of Set A. In some examples, for the sub use case beam management case 2, Set A and Set B may be different (Set B is not a subset of Set A) or Set B may be a subset of Set A or Set A and Set B may be the same.

For the sub use case beam management case 1 and beam management case 2, artificial intelligence or machine learning model training may be supported at the network entity side, at the UE side or both. In some examples, for the sub use case beam management case 1 and beam management case 2, the UE 115 and the network entity 105 may support downlink transmit beam prediction, downlink receive beam prediction, and beam pair prediction (where a beam pair includes a downlink transmit beam and a corresponding downlink receive beam) . To facilitate the artificial intelligence or machine learning model inference, the UE 115 and the network entity 105 may support enhanced or new configurations or UE reporting or UE measurement (e.g., enhanced or new beam measurement and/or beam reporting) , enhanced or new signaling for measurement configuration or triggering, and signaling of assistance information.

In some examples, a UE 115 may predict future instantaneous reference signal received powers and reference signal received power filtered and identify the best receive beam maintained by the UE 115. In some examples, the UE 115 may directly provide beam-pair link specific L1 reference signal received power predictions, and thus filtered L1 reference signal received powers or L1 signal interference to noise ratios and the best receive beams at future occasions may also be directly calculated with conventional filtering algorithms. In such cases, the UE 15 may not need to further refine it’s receive beams via actual downlink reference signal measurements, since the best receive beams were already identified based on such instantaneous reference signal received power prediction.

In some examples, the UE 115 may directly predict future filtered reference signal received powers. This may result in a lower artificial intelligence or machine learning complexity as no need to take receive beams into account for model input. For example, for 16 channel measurement resources, the input may be the 16 filtered L1 reference signal received powers or L1 signal interference to noise ratios (actually calculated or predicted) from previous cycles. In some examples, since the receive beams were not (virtually) determined during such prediction, the best receive beams at the predicted future occasions with respect to different channel measurement resources may not be derived. In some examples, a channel state information reference signal beamformed by the precoder may be the same as one of the channel measurement resources, with repetition set to on, and it should be expected to refine the receive beams before the UE 115 could be switched to a transmission configuration indicator state whose TypeD quasi co-located source reference signal is such a channel measurement resource.

In some examples, the UE 115 and the network entity 105 may support instantaneous reference signal received power prediction and reporting by the UE 115 and reference signal received power filtering by the network entity 105. In some examples, the UE 115 and the network entity 105 may support the best receive beam maintenance by the network entity 105. In some examples, this technique may offer lower UE complexity than where the UE 115 predicts future instantaneous reference signal received powers and reference signal received power filtered (as no filtering needed) . Additionally, in this example, there may not be a need for further receive beam refinement. In some examples, the UE 115 may report the receive beams (which consumes additional reporting overhead) that it identified for the predicted instantaneous reference signal received powers, so that the network entity 105 may calculate filtered reference signal received powers and maintain best receive beams.

In some examples, downlink transmission configuration indicator states activated or switched by network entity 105 may include receive beam information (since UE may not be aware of which Rx receive should be used for receiving the signals quasi co-location with the transmission configuration indicator states) .

According to one or more aspects of the present disclosure, the UE 115 may receive, from a network entity 105, a signal scheduling a channel state information report associated with a channel measurement resource set. The UE 115 may transmit, in response to the signal scheduling the channel state information report, capability information indicating that the UE 115 is capable of reporting a predicted set of future channel characteristics associated with the channel measurement resource set and a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles supported by the UE 115. The UE 115 may then transmit the channel state information report in accordance with the capability information.

FIG. 2 illustrates an example of a wireless communications system 200 that supports techniques for autonomous time domain beam prediction in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement or be implemented by aspects of the wireless communications system 100 described with reference to FIG. 1. For example, the wireless communications system 200 may include a UE 115-a (e.g., a network node) and a network entity 105-a (e.g., a network entity) , which may be examples of the corresponding devices described with reference to FIG. 1. The wireless communications system 200 may support improved autonomous time domain beam prediction, which may support improved communications between the network entity 105-a and the UE 115-a. For example, the wireless communications system 200 may support increased signaling efficiency and reduced power and resource overhead, among other benefits.

The wireless communications system 200 may support communications between the network entity 105-a and the UE 115-a. For example, the network entity 105-a may communicate signals with the UE 115-a over respective communication links 210, which may be an example of a communication link 125 described with reference to FIG. 1. In some cases, the network entity 105-a may transmit one or more reference signals (e.g., synchronization signal blocks, channel state information reference signals) to the UE 115-a via one or beams 205, where each reference signal may be associated with a reference signal resource identifier (e.g., index) . In some aspects, transmitting the reference signals may enable the network entity 105-a to sense its environment (e.g., in the wireless communications system 200) and predict whether a beam blockage may occur. In addition, the UE 115-a may measure a reference signal received power or other channel characteristic of one or more of the beams 205 and report the measurement information to the network entity 105-a. For example, the UE 115-a may measure and report reference signal received power values of particular beams to predict beam blockages.

In some aspects, the UE 115-a may receive a channel state information report configuration information 215 that includes a first set of one or more reference signal resource indications, each reference signal resource indication of the one or more reference signal resource indications corresponding to a respective reference signal resource (e.g., a respective) beam 205. That is, a beam 205 may be associated with a channel state information reference signal resource or a synchronization signal block resource. As such, the channel state information report configuration information 215 may identify one or more sets of channel state information or synchronization signal block resource identifiers, where each respective reference signal resource identifiers in the first set may correspond to a respective reference signal resource for which respective measurement information may be included in a report 220 (e.g., a channel state information report) for transmission to the network entity 105-a. For example, the respective reference signal resource identifiers may correspond to a beam 205-a, a beam 205-b, and a beam 205-c.

In some examples, the UE 115-a may transmit capability information 225 to the network entity 105-a. For examples, the UE 115-a may transmit capability information 225 indicating that the UE 115-a is capable of reporting a predicted set of future channel characteristics associated with the channel measurement resource set and a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles supported by the UE. According to one or more aspects, the network entity 105-a may request or trigger a measurement report for at least one of the set of channel measurement resources. To reduce UE overhead and improve reliability, the UE 115-a may indicate whether it supports of predicting a set of future channel characteristics. In some examples, the UE 115-a may receive the downlink control information signal (e.g., control signal 230) triggering the measurement report prior to or after the time duration in accordance with the capability information 225. The UE 115-a may then transmit the measurement report 220 in response to receiving the downlink control information signal.

According to one or more aspects depicted herein, the UE 115-a may report filtered L1 reference signal received powers and identifies preferred receive beams, based on predicted instantaneous L1 reference signal received powers. For example, the UE 115-a may measure one or more parameters corresponding to the one or more beams 205 and may predict a parameter associated with a receive beam. The UE 115-a may perform an autonomous time domain beam prediction to predict a parameter (e.g., reference signal received power or signal interference to noise ratio or both) corresponding to a receive beam. However, making the network entity 105-a aware of such autonomous time domain beam prediction at the UE 115-a may bring additional benefits on L1-report frameworks. For instance, the network entity 105-a may request the UE 115-a to start or stop time domain beam prediction autonomously, depending on network entity-side link adaptation performance, Doppler estimation at the network entity 105-a, speed estimation at the network entity 105-a (e.g., via sounding reference signal) , or positioning information or location information regarding the UE 115-a obtained from location management function, or a combination thereof.

In some examples, the UE 115-a may operate on a time domain beam prediction mode, depending on the network entity observations, the network entity 105-a may request the UE 115-a to extend or shorten its time domain beam prediction anchor periodicity. To achieve improved coordination between devices, aspects for the present disclosure provides for UE capability reporting and proactive indication on autonomous time domain beam prediction (and the associated anchor periodicity) . The techniques depicted herein may also support an ability for the network entity 105-a to indicate or control start or stopping of autonomous time domain beam prediction (and the associated anchor periodicity) .

According to one or more aspects, the UE 115-a may receive a signal 230 scheduling a channel state information report associated with a channel measurement resource set. The UE 115-a may transmit, in response to the signal 230 scheduling the channel state information report, capability information 225 indicating that the UE 115-a is capable of reporting a predicted set of future channel characteristics associated with the channel measurement resource set and a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles supported by the UE 115-a. In some examples, the UE 115-a may indicate at least one component on its autonomous time domain beam prediction behaviors. As a first component, when it is scheduled with a channel state information report to associated with a channel measurement set, the UE 115-a may indicate whether its reported parameters are at least based on predicted future channel characteristics associated with the channel measurement set. As a second component, the UE 115-a may further report a specific ratio (e.g., R) between a contiguous number of measurement cycles and a contiguous number of prediction cycles. In such cases, the UE 115-a may report one or more of L1 reference signal received power, L1 signal interference to noise ratio, precoding matrix indicator, a rank indicator, a channel quality indicator, or a combination thereof, based at least on actual channel measurements associated with the channel measurement resource set. In addition, the UE 115-a may report one or more of L1 reference signal received power, L1 signal interference to noise ratio, precoding matrix indicator, a rank indicator, a channel quality indicator, or a combination thereof, based on predicted future channel characteristics. The UE 115-a may transmit the channel state information report 220 in accordance with the capability information.

In some examples, at a certain prediction cycle, the UE 115-a may obtain predicted future channel characteristics associated with the prediction cycle based on historical channel measurements associated with the channel measurement set and/or historically predicted future channel characteristics associated with other historical prediction cycles. The UE 115-a may predict a set of future channel characteristics for a prediction cycle based on a set of historical channel characteristics associated with the channel measurement resource set. In such cases, transmitting the channel state information report 220 may include transmitting the channel state information report 220 including the predicted set of future channel characteristics. In some examples, the UE 115-a may predict a set of future channel characteristics for a prediction cycle based on a set of historical channel characteristics associated with a set of previous prediction cycles. In such cases, transmitting the channel state information report 220 may include transmitting the channel state information report 220 including the predicted set of future channel characteristics.

In some cases, the specific channel state information report 220 may not be further enhanced to indicate whether the report quantities are based on prediction or not. In some cases, the UE 115-a may report the capability information 225 as UE capabilities during initial access. Additionally, or alternatively, the UE 115-a may report the capability information 225 including the first component and the second component as UE capability during initial access. Alternatively, the UE 115-a may report the capability information 225 including the first component and the second component during initial access, and may further report an updated second component via a control message (e.g., MAC control element (MAC-CE) or uplink control information (UCI) ) . For example, the UE 115-a may transmit a control signal indicating an updated ratio between the contiguous number of measurement cycles and the contiguous number of prediction cycles supported by the UE 115-a. In some examples, the UE 115-a may report the capability information 225 including the first component, and may further report the second component via a control message (e.g., MAC-CE or UCI) .

In some examples, the UE 115-a may perform one or more measurements associated with the channel state information report 220. The UE 115-a may determine the updated ratio between the contiguous number of measurement cycles and the contiguous number of prediction cycles based on performing the one or more measurements. For example, the UE 115-a may be operating via a first ratio R₁ as its capability reporting when it is activated with a channel state information report. The UE 115-a may dynamically change the ratio to a second ratio R₂ according to its own observations or measurements. In such cases, the UE 115-a may feedback the updated ratio in the channel state information report as an additional reportQuantity, or update the ratio via MAC-CE. In some examples, if transmitting the updated ratio via MAC-CE, the UE 115-a may update the ratio as reported in the MAC-CE, after a threshold time period (e.g., X ms) from the slot where a feedback (e.g., acknowledgement) of the MAC-CE is received at the UE 115-a (where the value of X may be predefined) . In some cases, the UE 115-a may receive, from the network entity 105-a, an acknowledgement of the capability information 225. The UE 115-a may determine that a threshold time period has elapsed since receiving the acknowledgement. The UE 115-a may transmit a control signal indicating the updated ratio based on determining that the threshold time period has elapsed since receiving the acknowledgement. In some examples, such control signal (e.g., MAC-CE) may be applied to all active channel state information reports, or applied to a specific channel state information report by including the associated channel state information report setting identifier in the MAC-CE payload.

In some examples, the UE 115-a may indicate a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles supported by the UE 115-a via a MAC-CE. If reporting via MAC-CE, the UE 115-a may report the MAC-CE as soon as it is activated with any associated channel state information report. Additionally, or alternatively, the UE 115-a may directly report the ratio R that it applied to the reportQuantities in the same channel state information report as an additional reportQuantity. Ratios associated with different channel state information reports may be reported by the channel state information report separately.

According to one or more aspects depicted herein, the UE 115-a may report difference values for the first and second components. For example, the UE 115-a may report a first component including a predicted set of future channel characteristics associated with the channel measurement resource set and a second component including a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles supported by the UE 115-a. In some examples, the capability information may be on at least one of a type of report quantities, a number of channel measurement resources in the channel measurement resource set, a periodicity associated with the channel state information report, or a combination thereof. For example, the type of the report quantities may include a report supporting autonomous time domain prediction for L1 reference signal received power but may not support autonomous time domain prediction for L1 signal interference to noise ratio. In some examples, the UE 115-a may report ratio R₁ for L1 reference signal received power and may report ratio R₂ for L1 signal interference to noise ratio. In some examples, the UE 115-a report ratio R₁ for ≤8 channel measurement resources and may report ratio R₂ for >8 channel measurement resources. In some examples, the UE 115-a may report a ratio R₁ for periodicity ≤5 ms, and may report a ratio R₂ for >5 ms. In some examples, the UE 115-a may report ratio R₁ for L1 reference signal received power and periodicity ≤5 ms or both. Additionally, or alternatively, the UE 115-a may report ratio R₂ for L1 reference signal received power and periodicity >5 ms. Additionally, or alternatively, the UE 115-a may report ratio R₃ for L1 reference signal received power and periodicity >5 ms. Additionally, or alternatively, the UE 115-a may report ratio R₄ for L1 reference signal received power and periodicity >5 ms.

In some examples, the network entity 105-a may control UE autonomous time domain beam prediction behavior. The UE autonomous time domain beam prediction behavior may include enabling or disabling the time domain beam prediction behavior at the UE 115-a. The network entity 105-a may indicate whether the UE 115-a may address its reported one or more of L1 reference signal received power, L1 signal interference to noise ratio, precoding matrix indicator, a rank indicator, a channel quality indicator, or a combination thereof based on predicted future channel characteristics associated with the channel measurement resource set. Additionally, or alternatively, the UE 115-a may increase or decrease the ratio R associated with UE reported one or more of L1 reference signal received power, L1 signal interference to noise ratio, precoding matrix indicator, a rank indicator, a channel quality indicator, or a combination thereof. In some examples, the UE 115-a may receive, from the network entity 105-a, a signal enabling or disabling a capability of the UE 115-a to report the predicted set of future channel characteristics associated with the channel measurement resource set. In some examples, the UE 115-a may receive, from the network entity 105-a, a signal modifying the ratio between the contiguous number of measurement cycles and the contiguous number of prediction cycles supported by the UE 115-a. The signal transmitted by the network entity 105-a may be RRC configured, MAC-CE indicated, downlink control information switched, per serving cell or per BWP. For instance, the signal modifying the ratio may include at least one of an RRC signal, a MAC-CE, a downlink control information signal indicated for a set of channel state information reports, or a combination thereof. In some aspects, the RRC signal may be associated with at least one of a periodic channel state information report, an aperiodic channel state information report, a semipersistent channel state information report, or a combination thereof. The periodic channel state information report, or the aperiodic channel state information report, or the semipersistent channel state information report may be associated with a channel state information report setting. In some examples, the MAC-CE may activate a semipersistent channel state information report.

According to one or more aspects, the signal modifying the ration may be RRC configured for a specific aperiodic channel state information report in the associated CSI-AssociatedReportConfigInfo for the aperiodic channel state information report. Additionally, or alternatively, the network entity 105-a may transmit a downlink control information signal for a number of channel state information reports. In some examples, the network entity 105-a may use a MAC-CE to activate N options in terms of candidate ratios R. In some examples, the network entity 105-a may include a field of bits by a uplink grant downlink control information signal activating or triggering aperiodic channel state information report or semipersistent channel state information report, to select one of the activated ratios for all the aperiodic channel state information report, or the semipersistent channel state information report or both activated or triggered by the downlink control information signal. In some examples, the network entity 105-a may transmit a MAC-CE to activate N options for candidate ratios R. The network entity 105-a may transmit a field ofbits in a downlink control information signal, to select one of the activated ratios for all currently active channel state information reports.

Using the techniques described herein, the UE 115-a may transmit the report 220 to the network entity 105-a including the capability information, effectively using more than just prediction information. In fact, the techniques depicted herein provide for utilization of capability information to indicate a capability of a UE 115-a indicating that the UE 115-a is capable of reporting a predicted set of future channel characteristics associated with the channel measurement resource set and a ratio between a contiguous number of measurement cycles and a contiguous number of prediction cycles supported by the UE 115-a. As such, the network entity 105-a may use the capability information to request measurement report using predicted channel characteristics, which may result in fewer failed beams and transmissions and overall improved communications between the network entity 105-a and the UE 115-a.

Additionally, or alternatively, transmitting the channel state information report may include transmitting the channel state information report including the predicted set of future channel characteristics.

At 325, the UE 115-b may receive a signal modifying the ratio between the contiguous number of measurement cycles and the contiguous number of prediction cycles supported by the UE 115-b. In some examples, signal may include at least one of an RRC signal, a MAC-CE, a downlink control information signal indicated for a set of channel state information reports, or a combination thereof. In some examples, the RRC signal may be associated with at least one of a periodic channel state information report, an aperiodic channel state information report, a semipersistent channel state information report.

At 330, the UE 115-b may update prediction of a set of future channel characteristics for a prediction cycle based on a set of historical channel characteristics associated with the channel measurement resource set or a set of historical channel characteristics associated with a set of previous prediction cycles in accordance with receiving the signal modifying the ratio.
