User equipment uplink beam reporting in wireless communications

Abstract

Methods, systems, and devices for wireless communications are described that provide for updated uplink beam reports from a user equipment (UE). A UE may detect a changed condition associated with uplink communications, and may transmit a request for an update of a beam report to provide one or more uplink parameters. Such a UE may detect one or more changed conditions, such as due to a changed uplink beam pattern or uplink power backoff, and may request to update an uplink beam report or both an uplink and downlink beam report. A network entity may receive the request, and transmit an indication to the UE of an uplink resource for transmission of the uplink beam report, and the UE may transmit the uplink beam report using the indicated uplink resource.

[0034] In some existing wireless communications systems, a user equipment (UE) may provide one or more measurement reports that indicate channel conditions and / or measurements for signals (such as reference signals) that are received at the UE. In some cases, the measurement reports may contain one or more downlink metrics for multiple measured beams, and a network entity may select a beam for use in communications with the UE based on the reported downlink metrics. For example, a network entity (such as a base station, radio head, or transmission-reception pointAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO9(TRP)) may transmit multiple reference signals using directional transmissions along multiple associated spatial paths between the network entity and the UE, which may be referred to as beams, and the UE may provide metrics associated with multiple beams in the one or more measurement reports. The network entity may select one of the beams based on the one or more measurement reports, such as by selecting a beam that has a favorable channel condition for communications, and the selected beam may be used for subsequent downlink transmissions to the UE. Further, reciprocal beamforming parameters associated with the selected beam may be used for a reciprocal uplink beam for transmissions from the UE to the network entity.

[0035] However, in some scenarios the uplink beam that corresponds to the selected downlink beam may not be optimal for uplink communications, even though the downlink beam may have favorable channel conditions for downlink communications. For example, a UE may report two downlink reference signal beams, where a first downlink beam has a higher reference signal received power (RSRP) than a second downlink beam. In some cases, a corresponding first uplink beam that is a reciprocal beam of the first downlink beam may not be as favorable as a second uplink beam that is a reciprocal beam of the second downlink beam. Such a scenario may occur, for example, if the UE performs a power backoff for one or more antenna elements associated with the first uplink beam which is not performed for the second uplink beam, such as due to maximum permissible exposure (MPE) limits. In some wireless communications systems, UEs may provide uplink beam reports in addition to downlink beam reports, which may allow a network entity to account for conditions associated with uplink communications in beam selection. However, such uplink beam reports are transmitted in accordance with a periodic schedule or in response to a trigger from a network entity. In some scenarios, more dynamic uplink reporting to the network entity may be beneficial due to changes at the UE side, such as a changed quantity of available antenna elements at the UE, a changed uplink beam pattern due to UE device management (such as thermal management), or an uplink power backoff due to MPE conditions. Existing uplink beam reporting does not provide a mechanism for such dynamic uplink reporting.

[0036] In accordance with various aspects, a UE may transmit a request for an update of an uplink beam report to provide information related to one or more changedAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO10 conditions at the UE that impact uplink communications from the UE to a network entity. In some aspects, the UE may detect one or more changed conditions at the UE, such as due to a changed uplink beam pattern or uplink power backoff, and may request to update an uplink beam report or both an uplink and downlink beam report. The request may be transmitted, in some aspects, using one or more bits in an ongoing uplink transmission, using a configured physical uplink control channel (PUCCH) resource, using one or more configured bits of a downlink beam report, using a dedicated uplink resource, or any combination thereof. The network entity may receive the request, and may trigger an uplink beam report transmission. In some aspects, the UE may transmit a capability indication to the network entity that indicates a UE capability to request an updated uplink beam report, and the network entity may configure, such as by radio resource control (RRC) signaling, one or more uplink communications to include one or more bits to indicate the request, one or more uplink resources to transmit the request, or one or more random access messages that indicate the request. In some examples, the network entity may configure an uplink control information (UCI) type, a scheduling request (SR), or physical random access channel (PRACH) preamble that indicates the request from the UE. In some aspects, the network entity may receive the request from the UE, and transmit a downlink signal to the UE that indicates a resource for transmission of the uplink beam report from the UE. In some aspects, for uplink channel estimation, the UE may measure a downlink reference signal and apply an offset to estimate an associated uplink metric, may use assistance information provided by the network entity, or may derive an uplink metric based on an estimated pathloss of a channel and a configured uplink transmit power.

[0037] Particular aspects of the subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages. The techniques employed by the described communication devices may provide benefits and enhancements to the operation of the communication devices, including enhanced uplink communication reliability and data rates. For example, operations performed by the described communication devices may provide improvements to uplink beam selection by reporting of changed uplink conditions at a transmitting device that are used to select a favorable uplink beam. In some implementations, the operations performed by the described communication devices to provide uplink beam reportsAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO11 based on changed conditions may reduce a time duration for updating uplink communications parameters to account for the changed conditions, thereby reducing the probability of a communications failure for uplink communications. In some other implementations, operations performed by the described communication devices may also support improvements to power consumption, reliability for uplink communications, spectral efficiency, higher data rates and, in some examples, low latency for uplink communications, among other benefits.

[0038] 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, apparatus diagrams, system diagrams, and flowcharts that relate to UE uplink beam reporting in wireless communications.

[0039] Figure 1 shows an example of a wireless communications system 100 that supports UE uplink beam reporting in wireless communications in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (for example, 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.

[0040] 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 (for example, a radio frequency (RF) access link). For example, a network entity 105 may support a coverage area 110 (for example, 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 networkAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO12 entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs).

[0041] 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 Figure 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (for example, other wireless communication devices, including UEs 115 or network entities 105), as shown in Figure 1.

[0042] 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 (for example, any network entity described herein), a UE 115 (for example, 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.

[0043] 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 (for example, in accordance with an SI, N2, N3, or other interface protocol). In someAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO13 examples, network entities 105 may communicate with one another via backhaul communication link(s) 120 (for example, in accordance with an X2, Xn, or other interface protocol) either directly (for example, directly between network entities 105) or indirectly (for example, via the core network 130). In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (for example, in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (for example, 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 (for example, an electrical link, an optical fiber link) or one or more wireless links (for example, 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.

[0044] 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 (for example, 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 5GNB, a next-generation eNB (ng- eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, a network entity 105 (for example, a base station 140) may be implemented in an aggregated (for example, monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (for example, a network entity 105 or a single RAN node, such as a base station 140).

[0045] In some examples, a network entity 105 may be implemented in a disaggregated architecture (for example, 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 (for example, network entities 105), such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (for example, a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (for example, a cloud RAN (C-RAN)). For example, a network entity 105 may include one or more of a central unit (CU), such as aAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO14CU 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 (for example, 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 (for example, 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 (for example, a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0046] 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 (for example, 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 (for example, layer 3 (L3), layer 2 (L2)) functionality and signaling (for example, Radio Resource Control (RRC), service data adaptation protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 (for example, one or more CUs) may be connected to a DU 165 (for example, one or more DUs) or an RU 170 (for example, 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 (LI) (for example, physical (PHY) layer) or L2 (for example, 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 (for example, via one orAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO15 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 (for example, 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 (for example, Fl, Fl-c, Fl-u), and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (for example, 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 (for example, a channel) between layers of a protocol stack supported by respective network entities (for example, one or more of the network entities 105) that are in communication via such communication links.

[0047] In some wireless communications systems (for example, 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 (for example, to a core network 130). In some cases, in an IAB network, one or more of the network entities 105 (for example, 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 (for example, IAB donors) may be in communication with one or more additional devices (for example, IAB node(s) 104) via supported access and backhaul links (for example, backhaul communication link(s) 120). IAB node(s) 104 may include an IAB mobile termination (IAB-MT) controlled (for example, scheduled) by one or more DUs (for example, 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 (for example, of an RU 170) of IAB node(s) 104 used for access via the DU 165 of the IAB node(s) 104 (for example, referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB node(s) 104 may include oneAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO16 or more DUs (for example, DUs 165) that support communication links with additional entities (for example, IAB node(s) 104, UEs 115) within the relay chain or configuration of the access network (for example, downstream). In such cases, one or more components of the disaggregated RAN architecture (for example, the IAB node(s) 104 or components of the IAB node(s) 104) may be configured to operate according to the techniques described herein.

[0048] 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 UE uplink beam reporting in wireless communications as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (for example, a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (for example, components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180).

[0049] 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 (loT) device, an Internet of Everything (loE) 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.

[0050] 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 Figure 1.

[0051] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link(s) 125 (for example, one or more access links)Attorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO17 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 (for example, a bandwidth part (BWP)) that is operated according to one or more PHY layer channels for a given RAT (for example, LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (for example, 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 (for example, 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 (for example, a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (for example, directly or via one or more other network entities, such as one or more of the network entities 105).

[0052] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (for example, 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 (for example, 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 (for example, the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively higher quantity of resource elements (for example, 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 anAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO18RF spectrum resource, a time resource, and a spatial resource (for example, 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.

[0053] 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= l / (A / mflx■ Ay) seconds, for which fmaxmay 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 (for example, 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (for example, ranging from 0 to 1023).

[0054] 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 (for example, 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 (for example, 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 (for example, Ay) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

[0055] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (for example, 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 (for example, 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 (for example, in bursts of shortened TTIs (sTTIs)).Attorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO19

[0056] 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 (for example, 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 (for example, 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 (for example, 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 (for example, one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (for example, a specific UE).

[0057] In some examples, a network entity 105 (for example, 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 (for example, different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (for example, different coverage areas) may be supported by the same network entity (for example, 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 (for example, 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 (for example, different coverage areas) using the same or different RATs.Attorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO20

[0058] 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.

[0059] In some examples, a UE 115 may be configured to support communicating directly with other UEs (for example, one or more of the UEs 115) via a device-to- device (D2D) communication link, such as a D2D communication link 135 (for example, 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 (for example, a base station 140, an RU 170), which may support aspects of such D2D communications being configured by (for example, 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.

[0060] 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 (for example, a mobility management entity (MME), an access and mobilityAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO21 management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (for example, 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 (for example, 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.

[0061] 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 (for example, 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.

[0062] 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 (for example, LAA). OperationsAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO22 using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0063] A network entity 105 (for example, 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.

[0064] 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 (for example, a network entity 105, a UE 115) to shape or steer an antenna beam (for example, 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 (for example, with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).Attorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO23

[0065] 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.

[0066] In some aspects, one or more UEs 115 may provide measurement reports, or beam reports, that indicate measurements of downlink reference signals, which may be used for beam selection for subsequent communications. In some implementations, in addition to measurements associated with downlink reference signals, one or more beam reports may include one or more parameters associated with uplink beams from a UE 115. In some aspects, one or more UEs 115 may detect a changed condition associated with uplink communications, and may transmit a request for an update of a beam report to provide one or more uplink parameters. In some implementations, such a UE 115 may detect one or more changed conditions, such as due to a changed uplink beam pattern or uplink power backoff, and may request to update an uplink beam report or both an uplink and downlink beam report. A network entity 105 may receive the request, and transmit an indication to the UE 115 of an uplink resource for transmission of the uplink beam report, and the UE 115 may transmit the uplink beam report using the indicated uplink resource.

[0067] Figure 2 shows an example of a portion of a wireless communications system 200 that supports UE uplink beam reporting in wireless communications in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may include a UE 215, and a network entity 205 with coverage area 210, which may be examples of a UE 115 and a network entity 105, as described with reference to Figure 1.Attorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO24

[0068] In the wireless communications system 200 of Figure 2, the UE 215 and the network entity 205 may have multiple beams available for communications, including a first beam that corresponds to a line of sight path between the UE 215 and the network entity 205 and that supports a first downlink communication link 220 and a first uplink communication link 225. The multiple beams also may include a second beam that corresponds to a non-line-of-sight path via a reflector 230, and that supports a second downlink communication link 235 and a second uplink communication link 240. The UE 215 may measure one or more parameters associated with each beam, and in some examples may measure a first RSRP associated with the first downlink communication link 220 that is higher than a second RSRP associated with the second downlink communication link 235. The UE 215 may provide a measurement report that indicates the measured RSRP values, and the network entity 205 may select the first beam, and the first downlink communication link 220 and the first uplink communication link 225, for communications between the network entity 205 and the UE 215.

[0069] As discussed herein, in some aspects the UE 215 also may provide one or more uplink parameters in a measurement report, such as an uplink measurement report that is separate from a downlink measurement report, or a combined measurement report that includes both downlink and uplink parameters. In some aspects, the UE 215 may determine that one or more uplink parameters have changed since a prior measurement report that provides uplink parameters. For example, an MPE change at the UE 215 may result in a lower available uplink transmit power for the first uplink communication link 225, but not for the second uplink communication link 240 (such as due to different antennas associated with the different links). In accordance with various aspects, the UE 215 may transmit a request for an update of an uplink beam report to provide information related to the one or more changed conditions at the UE 215. In some aspects, the UE 215 may request to update an uplink beam report or both an uplink and downlink beam report. The request may be transmitted, in some aspects, using one or more bits in an ongoing uplink transmission, using a configured PUCCH resource, using one or more configured bits of a downlink beam report that is transmitted to the network entity 205, using a dedicated uplink resource, or any combination thereof. The network entity 205 may receive the request, and may trigger an uplink beam report transmission. The UE 215 may transmit a measurement reportAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO25 with one or more uplink parameters, which may be used by the network entity 205 to select a same or a different beam for uplink and / or downlink communications. In some implementations, the UE 215 may measure downlink reference signals on each of the first downlink communication link 220 and the second downlink communication link 235, which may correspond to two narrow channel state information (CSI) reference signal beams that are quasi-co-located (QCLed) with a same SSB beam or two different SSB beams.

[0070] In some aspects, the UE 215 may transmit a capability indication to the network entity 205 that indicates a UE 215 capability to request an updated uplink beam report, and the network entity 205 may configure, such as by RRC signaling, the UE 215 to transmit the request and associated uplink beam report. In some aspects, the UE 215 may transmit a joint uplink and downlink beam report, and may report a top N downlink and uplink beams, respectively, and the network entity may select beams for subsequent communications based on the report. In some aspects, to reduce overhead, the UE 215 may report N beams with both downlink and uplink metrics per reported beam. Further, in some aspects beam metrics may be provided in a cell report for lower layer triggered mobility, where both downlink and uplink beam metrics can be reported per reported candidate cell.

[0071] As discussed herein, in some aspects the UE 215 may transmit a request to provide an updated uplink beam report. Such a request may be transmitted based on one or more conditions that are present at the UE 215, and that the network entity 205 may not be aware of such conditions at the UE 215. For example, the conditions at the UE 215 may include an uplink beam pattern that is changed due to fewer antenna elements that are available per uplink port at the UE 215 (such as illustrated in Figure 3). Additionally, or alternatively, the conditions at the UE 215 may include an uplink beam pattern associated with a transmission configuration indicator (TCI) that is dynamically updated at the UE 215 due to device management (such as thermal management or power management at the UE 215). Additionally, or alternatively, the conditions at the UE 215 may include an uplink power backoff (such as due to MPE) that occurred but did not trigger a separate MPE report.

[0072] In some implementations, the request from the UE 215 may be provided in a single bit indicator to indicate whether an update of an uplink beam report is requested,Attorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO26 where the indicator may be included in an ongoing uplink transmission. In some other implementations, the request from the UE 215 may be provided in a dedicated PUCCH resource that is configured for requesting for resources for an updated uplink report (such as a one or multi-bit PUCCH resource that indicates the request). In further implementations, the request from the UE 215 may be provided using one or more bits of a downlink beam report that is transmitted by the UE 215 (such as a reserved bit in a periodic, semi-persistent, or aperiodic downlink beam report). In still further implementations, the request from the UE 215 may be provided using a dedicated uplink resource, such as a resource that is configured by RRC. In some aspects, one or more of these techniques may be available for the UE 215 to transmit the request. The network entity 205 may trigger an uplink beam report based on the request.

[0073] In some aspects, depending on a UE 215 capability, the network entity 205 may configure the UE 215 with an uplink resource configuration to send the request. In some implementations, the request may be indicated in an uplink control information (UCI) message (such as by using a UCI type that is associated with a request for an updated uplink beam report), the request may be indicated in a scheduling request (such as a scheduling request having a format that indicates the request), in a dedicated PRACH preamble (such as a configured preamble that indicates the request), or any combination thereof. The network entity 205, upon receiving the request, may transmit a downlink signal to indicate a resource for the UE 215 to transmit the updated uplink beam report. In some implementations, the downlink signal may use an existing downlink control information (DCI) format, or may use a DCI format that is defined for transmission of such a request. Additionally, or alternatively, the network entity 205 may configure periodic resources (such as in a configured grant of periodic resources) that may be used to transmit the uplink beam report. In some implementations, the UE 215 may transmit the request, and may transmit the uplink beam report using one of the configured uplink resources that is within a configured time duration from the transmission of the request (such as within X symbols after sending the request).

[0074] In some aspects, one or more parameters included in the uplink beam report may be determined by the UE 215 based on one or more downlink reference signal measurements. In some implementations, for an uplink RSRP estimation, the UE 215 may use a downlink reference signal measurement corresponding to the beam to firstAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO27 get the downlink RSRP and then derive an associated uplink RSRP. In some implementations, the downlink reference signal may be a QCLed reference signal in the TCI of the uplink beam. In some aspects, the network entity 205 may provide assistance information that may be used by the UE 215 to estimate one or more uplink parameters. For example, the UE 215 may derive an uplink RSRP based on an uplink configured transmit power minus a measured downlink RSRP, plus an offset value provided by the network entity 205 (that is, UL RSRP = UL configured Tx Power - DL RSRP + offset). The offset may be configured by the network entity 205 to compensate for a higher downlink transmit power relative to an uplink transmit power. In some implementations, the UE 215 may estimate a pathloss and derive an uplink RSRP based on the pathloss. For example, a pathloss reference signal (such as a CSI reference signal) corresponding to an uplink reference signal may be used to estimate a downlink pathloss, and the downlink pathloss may be used to derive the uplink RSRP (that is, UL RSRP = UL configured Tx Power - pathloss). In some implementations, the measurement report from the UE 215 may include downlink metrics, such as downlink RSRP for the same reference signal, or a different set of downlink reference signals configured for a downlink report.

[0075] Figure 3 shows an example of a portion of a wireless communications system 300 that supports UE uplink beam reporting in wireless communications in accordance with one or more aspects of the present disclosure. The wireless communications system 300 may include a UE 315, and a network entity 305, which may be examples of UEs and network entities as described with reference to Figures 1 and 2.

No. 2405750WO60 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 (for example, 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.

[0202] 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.

[0203] 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.

[0204] As used herein, including in the claims, “or” as used in a list of items (for example, 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.”

[0205] 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 mayAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO62 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.”

[0206] 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 (for example, receiving information), accessing (for example, accessing data stored in memory), and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.

[0207] 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.

[0208] 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.

[0209] 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 beAttorney Docket No. PY2644.WO (114958.TBD)Qualcomm Ref. No. 2405750WO63 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.
