[0002] The following relates to wireless communications, including techniques for allocating non-linear distortion to spatial layers.BACKGROUND

[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE- Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE).Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref.

[0060] In some examples, a wireless communication system may include a user equipment (UE) transmitting messages to a network entity. To perform the transmissions, the UE may contain non-linear (NL) components, such as high power amplifiers (PA) with a limited linear dynamic range, and the NL components may distort the transmitted signals due to high peak-to-average power ratio (PAPR). The NL distortions may be in-band distortion that affects the link performance in the sense of mutual information or error vector magnitude (EVM) and out-band (OOB) distortion, that may have limits due to regulatory constraints. To minimize the distortions, power back-off (BO) may be introduced; however, a higher BO may result in less power efficiency with less power being transmitted to the medium and more power being dissipated as heat.

[0061] Techniques for allocating NL distortion to spatial layers may be employed. In some examples, a transmitter may balance or control the NL distortion by shifting NL distortion from one spatial layer to another spatial layer associated with multiple input multiple output (MIMO) techniques using multiple antennas. For example, a UE may receive a distortion management configuration for an uplink transmission. The distortion management configuration may indicate a plurality of spatial layers that the UE is to use for an uplink transmission, and the distortion management configuration may indicate a proportion of NL distortion to allocated to a respective spatial layer of the plurality of spatial layers. The UE may receive a control message indicating to transmit an uplink message. The UE may precode the uplink message to generate a precoded message for transmission via the plurality of spatial layers in accordance with the distortion management configuration. The UE may transmit the precoded message via the plurality of spatial layers in accordance with the control message. In someAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO14examples, the distortion management configuration may indicate one or more frequencies associated with each spatial layer of the plurality of spatial layers, and the distortion management configuration may indicate the proportion of NL distortion to apply to the one or more frequencies. The frequencies may be in-band frequencies or out-of-band frequencies. The proportion of NL distortion to apply to a respective spatial layer of the plurality of spatial layers may be based on a quality of service of a data payload of the uplink message or a channel characteristic.

[0062] 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 block diagrams, process flow, apparatus diagrams, system diagrams, and flowcharts that relate to techniques for allocating NL distortion to spatial layers.

[0063] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for allocating NL distortion to spatial layers in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105), one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE- Advanced (LTE- A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0064] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link(s) 125 (e.g., a radio frequency (RF) access link). For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link(s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO15UE 115 may support the communication of signals according to one or more radio access technologies (RATs).

[0065] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105), as shown in FIG. 1.

[0066] 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.

[0067] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link(s) 120 (e.g., in accordance with an SI, N2, N3, or other interface protocol). In some examples, network entities 105 may communicate with one another via backhaul communication Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO16link(s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130). In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication link(s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link), among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.

[0068] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB), a 5GNB, a next-generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140).

[0069] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105), such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, a network entity 105 may include one or more of a central unit (CU), such as a CU 160, a distributed unit (DU), such as a DU 165, a radio unit (RU), such as an RU 170, a RAN Intelligent Controller (RIC), such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO)Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO17system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0070] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), service data adaptation protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs), or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (LI) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170). In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). A CU 160 may beAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO18functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., Fl, Fl-c, Fl-u), and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.

[0071] In some wireless communications systems (e.g., the wireless communications system 100), infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130). In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node(s) 104) may be partially controlled by each other. The IAB node(s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station). The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node(s) 104) via supported access and backhaul links (e.g., backhaul communication link(s) 120). IAB node(s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node(s) 104 used for access via the DU 165 of the IAB node(s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB node(s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node(s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream). In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node(s) 104 or components of the IAB node(s) 104) may be configured to operate according to the techniques described herein.Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO19

[0072] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor), IAB node(s) 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, an IAB donor may refer to a RAN node with a wired or wireless connection to the core network 130. The IAB donor may include one or more of a CU 160, a DU 165, and an RU 170, in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and IAB node(s) 104 may communicate via an Fl interface according to a protocol that defines signaling messages (e.g., an Fl AP protocol). Additionally, or alternatively, the CU 160 may communicate with the core network 130 via an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs (e.g., including a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of another portion of a backhaul link.

[0073] IAB node(s) 104 may refer to RAN nodes that provide IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities). A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node(s) 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with IAB node(s) 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through other IAB node(s) 104). Additionally, or alternatively, IAB node(s) 104 may also be referred to as parent nodes or child nodes to other IAB node(s) 104, depending on the relay chain or configuration of the AN. The IAB-MT entity of IAB node(s) 104 may provide a Uu interface for a child IAB node (e.g., the IAB node(s) 104) to receive signaling from a parent IAB node (e.g., the IAB node(s) 104), and a DU interface (e.g., a DU 165) may provide a Uu interface for a parent IAB node to signal to a child IAB node or UE 115.

[0074] For example, IAB node(s) 104 may be referred to as parent nodes that support communications for child IAB nodes, or may be referred to as child IAB nodes associated with IAB donors, or both. An IAB donor may include a CU 160 with a wired or wireless connection (e.g., backhaul communication link(s) 120) to the core network 130 and may act as a parent node to IAB node(s) 104. For example, the DU 165 of anAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO20IAB donor may relay transmissions to UEs 115 through IAB node(s) 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment via an Fl interface to IAB node(s) 104, and the IAB node(s) 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through one or more DUs (e.g., DUs 165). That is, data may be relayed to and from IAB node(s) 104 via signaling via an NR Uu interface to MT of IAB node(s) 104 (e.g., other IAB node(s)). Communications with IAB node(s) 104 may be scheduled by a DU 165 of the IAB donor or of IAB node(s) 104.

[0075] 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 allocating NL distortion to spatial layers as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180).

[0076] 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.

[0077] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO21

[0078] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link(s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link(s) 125. For example, a carrier used for the communication link(s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105).

[0079] 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 schemeAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO1may 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.

[0080] 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 / max■ Ay) seconds, for which fmaxmay represent a supported subcarrier spacing, and Ay 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).

[0081] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Ay) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

[0082] 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)).Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO23

[0083] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE).

[0084] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105). In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105). The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.

[0085] 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 toAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO24support 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.

[0086] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170), which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1 :M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.

[0087] 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 planeAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO25entity 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.

[0088] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0089] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO26

[0090] 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 (MEMO) 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.

[0091] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas.Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices.

[0092] 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 spatialAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO27path 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).

[0093] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link(s) 125, a D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal -to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

[0094] In some examples, a wireless communication system may include the UE 115 transmitting messages to the network entity 105. To perform the transmissions, the UE 115 may contain NL components, such as PAs with a limited linear dynamic range, and the NL components may distort the transmitted signals due to high PAPR. The NL distortions may be in-band distortion that affects the link performance in the sense of mutual information or EVM and OOB distortion, that may have limits due to regulatory constraints. To minimize the distortions, power BO may be introduced; however, a higher BO may result in less power efficiency with less power being transmitted to the medium and more power being dissipated as heat.Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO28

[0095] Techniques for allocating NL distortion to spatial layers may be employed. In some examples, a transmitter may balance or control the NL distortion by shifting the NL distortion from one spatial layer to another spatial layer associated with multiple input multiple output (MIMO) techniques using multiple antennas. For example, a UE 115 may receive a distortion management configuration for an uplink transmission. The distortion management configuration may indicate a plurality of spatial layers that the UE 115 is to use for an uplink transmission, and the distortion management configuration may indicate a proportion of NL distortion to allocate to each spatial layer of the plurality of spatial layers. The UE 115 may receive a control message indicating to transmit an uplink message. The UE 115 may precode the uplink message to generate a precoded message for transmission via the plurality of spatial layers in accordance with the distortion management configuration. The UE 115 may transmit the precoded message via the plurality of spatial layers in accordance with the control message. In some examples, the distortion management configuration may indicate one or more frequencies associated with a respective spatial layer of the plurality of spatial layers, and the distortion management configuration may indicate the proportion of NL distortion to apply to the one or more frequencies. The frequencies may be in-band frequencies or out-of-band frequencies. The proportion of NL distortion to apply to each spatial layer of the plurality of spatial layers may be based on a quality of service of a data payload of the uplink message or a channel characteristic.

[0096] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for allocating NL distortion to spatial layers in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement aspects of or may be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 includes a UE 115-a, a network entity 105-a, and a network entity 105-b, which may be examples of a UE 115 and a network entity 105 as described herein.

[0097] The UE 115-a may communicate with the network entity 105-a using a communication link 125-a. The communication link 125-a may be an example of a 6th generation (6G), a NR or LTE link between the UE 115-a and the network entity 105-a. The communication link 125-a may include bi-directional links that enable both uplink and downlink communications. For example, the network entity 105-a may transmitAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO29downlink signals (e.g., downlink message 205), such as downlink control signaling and downlink data signals, to the UE 115-a using the communication link 125-a, and the UE 115-a may transmit uplink signals (e.g., uplink message 210), including uplink control signaling and uplink data signals to the network entity 105- a using the communication link 125-a.

[0098] The network entity 105-a may communicate with the network entity 105-b using a communication link 215. The communication link 215 may be an example of a backhaul communication link 120, midhaul communication link 162, fronthaul communication link 168, or another communication link. The communication link 215 may include bi-directional links. For example, the network entity 105-a may transmit signals to the network entity 105-b using the communication link 215, and the network entity 105-b may transmit signals to the network entity 105-a using the communication link 215.

[0099] In some examples, the UE 115-a may transmit the uplink message 210 to the network entity 105-a. The utilization efficiency of a radiated power to transmit the uplink message may play a significant role in wireless system design. The UE 115-a may include a transmitter that includes NL components, such as high-power amplifiers (PA) with a limited linear dynamic range, and the PAs may distort the transmitted signal due to high PAPR. A source of NL distortion may be from pushing the PA to a NL region to benefit from increased energy efficiency. The NL distortions may be classified as in-band distortion that affects the communication link performance in the sense of mutual information or error vector magnitude (EVM) and out of band (OOB) distortion that may have some limits due to regulatory constraints. To avoid or reduce the in-band and OOB distortions, a power back-off (BO) may be introduced, however, the power BO may be associated with a downside. For example, higher power BO reduces the power efficiency, so less power is transmitted to the medium and more power is dissipated as heat.

[0100] In some examples, the transmitter may implement alternatives to power BO. For example, the transmitter may implement PAPR reduction schemes which reduce the PAPR of the signal at the input of the PA to allow the application of a smaller power BO with improved PA efficiency. The PAPR reduction schemes may use extra bandwidth, limited EVM and in general do not reduce the PAPR below threshold values Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO30without performance reductions. Another alternative may be a digital pre-distorter (DPD). The DPD may linearize the NL polynomial response of the PA up to a clipping level and may reduce the BO up to a theoretical PAPR level. Another alternative may be digital post distortion (DPoD) that, like the DPD, may linearize the NL response of the PA in the receiver. The DPoD performance may be similar to the DPD. These alternatives may not deal with clipping that limits the performance, and these alternatives do not use the spatial domain.

[0101] For MIMO with multiple ports in the transmitter of the UE 115-a, the NL distortion from the PA may not be the same among the multiple ports over the time. At any given time, the NL distortion of the PA on port A may be different than the NL distortion of the PA on port B. This difference in NL distortion between the ports is correct if the signal is different per port; for example, due to precoding or multi-layer transmission. The different signal per port provides a different instantaneous power (IP) per port at any given time, and since the impact of the PA strongly depends on the IP, the impact of the PA is different per port. In some cases, the PA impact per port may be balanced or controlled. The NL distortion effect at one port may be shifted to another port per instant with controlled effect on the OOB and EVM.

[0102] FIG. 3 shows an example of a block diagram 300 that supports techniques for allocating NL distortion to spatial layers in accordance with one or more aspects of the present disclosure. The block diagram 300 may implement aspects of or may be implemented by aspects of the wireless communications system 100 and wireless communications system 200. For example, the block diagram 300 may be implemented by the UE 115-a and the network entity 105-a.

[0103] The block diagram 300 illustrates a technique for allocating NL distortion to spatial layers for a transmitter device (e.g., UE 115-a or network entity 105-a) and a receiver device (e.g., UE 115-a or network entity 105-a). At the transmitter device, information bits in block 302 feeds to a encoder + mapper block 304. After the encoder + mapper block 304, the information bits are a frequency domain signal with L layers, where L is a positive integer. The receiver device may include the make precoding block 306 that precodes the frequency domain signal with L layers to N transmitter ports (wideband precoding (WB) or sub-band precoding (SB)). From the make precoding block 306, a frequency domain signal with N transmitter ports may be fed toAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO31an inverse fast Fourier transform (IFFT) block 308 that converts the frequency domain signal for transmission onto available subcarriers that feeds to an oversampling factor (OSF) block 310. After the OSF block 310, is a digital to analog converter (DAC) block 312 and a PA 314. After the PA 314, the signal is transmitted over the channel 334 to the receiver device. In some cases, a PAPR reduction and a DPD may be implemented between the OSF block 310 and the DAC block 312. For example, the PAPR reduction and DPD may deal with the PA 314 while the precoding is matched to the over the air (OTA) channel. In some examples, using the PAPR reduction and DPD may find local optimums but not a global optimum.

[0104] For the transmitter device with allocation of NL distortion to spatial layers, the PAPR reduction and DPD may not be used. Instead of the PAPR reduction and DPD, the transmitter device may include a distortion management block 316. The frequency domain signal with L layers may be fed to the distortion management block 316. The transmitter device with allocation of NL distortion to spatial layers includes a make precoding block 318, an IFFT block 320, a OSF block 322, a PA model block 324, a down sample block 326, a fast Fourier transform (FFT) block 328, a channel model block 330 and a demapper block 332. The output of the demapper block 332 of L equalized symbols is fed to the distortion management block 316 that outputs the allocated distortion for the L layers. The transmitter device with allocation of NL distortion to spatial layers solves the global optimum instead of the local optimum provided by the PAPR reduction and DPD. The receiver device includes a ADC block 336, a down sample block 338, a FFT block 340, a demapper block 342, and a decoder block 344, which outputs bits decoded from the received signal. The receiver device remains the same as a baseline receiver and is not affected by the allocation of NL distortion by the transmitter device. In the proposed scheme, the OTA channel as well as the NL model of the PAs are known to the transmitter device. The NL distortion allocation technique may iteratively determine or model an optimal distortion per layer due to the entire end-to-end (E2E) model of the precoder, the PA, the channel, and the decoder, and the NL distortion allocation technique may control the total distortion by distributing it among the layers or dimensions (e.g., spatial layers, frequency, other dimensions, or other subdimensions).Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO32

[0105] FIG. 4 shows an example of a block diagram 400 that supports techniques for allocating NL distortion to spatial layers in accordance with one or more aspects of the present disclosure. The block diagram 400 may implement aspects of or may be implemented by aspects of the wireless communications system 100 and wireless communications system 200. For example, the block diagram 400 may be implemented by the UE 115-a and the network entity 105-a. The block diagram 400 illustrate aspects of the distortion management block 316 of the block diagram 300.

[0106] The distortion management block 316 of the block diagram 300 determines the amount of NL distortion to allocate to each of the layers or other dimensions. The block diagram 400 illustrates an input of the L original symbols 402 from the encoder + mapper block 304 and an input of L equalized symbols of iteration j 404 from the demapper block 332 to a subtracting junction 406, where j is a positive integer. After the subtracting junction 406, the signal is L predicted distortion 408. The input to a summing junction 410 include the L predicted distortion 408 that is summed with the iteration j 412. The output from the summing junction 410 is input to a add weight on the dimension of interest block 414. In some cases, the weighting is from zero to one, and the weighting may indicate the level of NL distortion to allocate to the dimension or subdimension. In some cases, the weighting may be provided by a distortion management matrix, and the distortion management matrix may indicate a weighting factor to apply to a respective dimension of a plurality of dimensions. In some cases, the dimension of interest may be a spatial domain or a frequency domain. The weighting may be viewed as pouring the NL distortion into the different dimension, where the more NL distortion poured into the dimension would contaminate the dimension with the NL distortion. The amount of the allocated or poured distortion may be determined based on a quality associated with a specific dimension. For example, the amount of NL distortion allocated to a specific dimension may depend on a quality of service (QoS), a signal-to-noise ratio (SNR) of the channel, or an interference of the channel. The output of the add weight on the dimension of interest block 414 is L distortion to subtract iteration j 416. Referring to FIG. 2, the distortion management block may allocate or pour the NL distortion to four spatial layers (e.g., layer 1 220, layer 2225, layer 3 230, and layer 4235). Each layer or dimension may be allocated a respective NL distortion level 240. The distortion management block may allocate the distortion into theAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO33different layers or dimensions, and the NL distortion may vary among the layers in both OOB and EVM. For example, A% of the NL distortion may be allocated to a first layer, B% may be allocated to a second layer, and so forth, where A and B may be numbers that are the same or different. The distortion management block may manage the distortion on the layer domain. The level of NL distortion may be a function of the total NL energy due to the set of NL PAs.

[0107] Referring to FIG. 2, the allocation of the NL distortion may be performed by the transmitter device. For cases in which the transmitter is the UE 115-a for transmission of the uplink message 210, the network entity 105-a may indicate how much distortion to allocate or pour per layer, subject to network requirements. For example, the UE 115-a may receive, from the network entity 105-a, a control signal 245 that indicates a distortion management configuration for an uplink transmission by the UE 115-a. In some cases, the distortion management configuration may indicate a plurality of spatial layers to use and may indicate a proportion of NL distortion to allocate a respective spatial layer of the plurality of spatial layers. The network entity 105-a may indicate where in frequency to allocate or pour the NL distortion. For example, the distortion management configuration may indicate one or more frequencies associated with a respective spatial layer of the plurality of spatial layers, and the distortion management configuration may indicate the proportion of NL distortion to allocate to the one or more frequencies. The frequencies may be in-band frequencies with impact on EVM or OOB frequencies, single or dual sided. The distortion management configuration may indicate to allocate the NL distortion on a specific set of frequencies. In some cases, the distortion management configuration indicates a distortion management matrix, and the distortion management matrix indicates a weighting factor to apply to a respective spatial layer of the plurality of spatial layers. For cases in which the transmitter is the network entity 105-a for transmission of the downlink message 205, the network entity 105-a may allocate the NL distortion to the plurality of spatial layers and may allocate the NL distortion to the to the one or more frequencies.

[0108] The UE 115-a may receive, from the network entity 105-a, a control message 250 indicating to transmit the uplink message. The UE 115-a may allocate the NL distortion as indicated in the distortion management configuration using the techniquesAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO34illustrate in FIGs. 3 and 4. The UE 115-a may precode the uplink message to generate a precoded message for transmission via the plurality of spatial layers in accordance with the distortion management configuration. The UE 115-a may transmit, to the network entity 105-a, the precoded message 255 via the plurality of spatial layers.

[0109] In some cases, to accommodate the allocation of the NL distortion to spatial layers or other dimensions, performance metrics may be defined per layer or per dimension rather than per port or per transmitter array. For example, the UE 115-a and network entity 105-a may determine a performance metric associated with the precoded message 255, and the performance metric may be determined for the plurality of spatial layers. The performance metric may be an EVM metric or an OOB metric associated with each spatial layer of the plurality of spatial layers or each of the dimensions of the plurality of dimensions.

[0110] In some cases, the network entity 105-a may coordinate with the network entity 105-b to control the NL distortion on a specific layer of a specific node connected to the network entity 105-b. For example, the network entity 105-a and the network may send signaling with a request to control the NL distortion on a specific layer of a specific node and to allocate the NL distortion for a specific node. For example, the network entity 105-a may receive, from the network entity 105-b, a control signal 260 that indicates a distortion management configuration associated with one or more spatial layers of a plurality of spatial layers, and second distortion management configuration may indicate, to the network entity 105-a, to apply a NL distortion or to refrain from applying the NL distortion to the one or more spatial layers of the plurality of spatial layers. In some cases, the network entity 105-a may transmit, to the network entity 105-b, a control signal 265 indicating a distortion management configuration associated with one or more spatial layers of the plurality of spatial layers, and the distortion management configuration may indicate, to the network entity 105-b, to apply a NL distortion or to refrain from applying the NL distortion to the one or more spatial layers of the plurality of spatial layers.[OHl] In some cases, the receiving device may deliver the MIMO channel to the transmitter device. For example, the UE 115-a may receive, from the network entity 105-a, an indication of a channel matrix for the uplink transmission. The UE 115-a may precode the uplink message based on the channel matrix.Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO35

[0112] In some cases, the amount of the NL distortion to allocate to the layers may be determined as a function of QoS. For example, the proportion of NL distortion to allocate to a respective spatial layer of the plurality of spatial layers may be based on a quality of service of a data payload of the uplink message. In some cases, the UE 115-a may receive, from the network entity 105-c, a control signal that indicates a quality of service indicator associated with the uplink message, and the proportion of NL distortion to apply to a respective spatial layer of the plurality of spatial layers may be based on the quality of service indicator. In some cases, the network entity 105-c may indicate, to the UE 115-a, to allocate some A% of total NL distortion on layers on which the HARQ retransmissions are sent, while allocating B% of the total NL distortion on the layers on which first transmissions occur (e.g., an initial instance of attempting to send a message in a transmission). The differentiation between the layers may be due to other different reasons, such as the QoS indicator coming from upper layers. In some cases, the amount of the NL distortion to allocate to the layers may be determined as a function of a channel characteristic.

[0113] The techniques for allocating NL distortion to spatial layers may use advantages of the multiple input multiple output (MIMO) or multi-TX domain and may introduce a way to allocate or pour the NL distortion into different layers to improve the PA(s) efficiency. The techniques for allocating NL distortion may allow the transmitter device to manage the NL distortion across the spatial layers. The technique may exploit knowledge of the OTA MIMO channel and knowledge of NL model of the PA(s) to (iteratively) be able to control the distortion per layer. The technique may exploit the extra degree of freedom that the NL effect is not the same across transmitter ports at any given instant time and balances this a-symmetry. The techniques allow the transmitter to push the PA(s) to work at noticeably lower values of BO, which boosts the power efficiency. The performance EVM and OOB may be different per layer.

[0114] FIG. 5 shows an example of a process flow 500 that supports techniques for allocating NL distortion to spatial layers in accordance with one or more aspects of the present disclosure. The process flow 500 may implement or may be implemented by aspects of the wireless communications system 100 and the wireless communications system 200. For example, the process flow 500 may include a UE 115-b and a network entity 105-c which may be examples of corresponding devices and entities as describedAttorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO36with reference to FIGs. 1 and 2. In the following description of the process flow 500, the operations between the UE 115-b and the network entity 105-c may be transmitted in a different order than the example order shown, or the operations performed by the UE 115-b and the network entity 105-c may be performed in different orders or at different times. Some operations may also be omitted from the process flow 500, and other operations may be added to the process flow 500.

[0115] At 505, the UE 115-b may receive, from the network entity 105-c, a control signal that indicates a distortion management configuration for an uplink transmission by the UE. The distortion management configuration may indicate a plurality of spatial layers to use, and the distortion management configuration may indicate a proportion of NL distortion to allocate to each spatial layer of the plurality of spatial layers.

[0116] In some examples, the distortion management configuration may indicate one or more frequencies associated with each spatial layer of the plurality of spatial layers, and the distortion management configuration may indicate the proportion of NL distortion to allocate to the one or more frequencies. The one or more frequencies may include one or more in-band frequencies or one or more out-of-band frequencies. In some cases, the proportion of NL distortion to allocate to each spatial layer of the plurality of spatial layers may be based on a channel characteristic. In some examples, the distortion management configuration may indicate a distortion management matrix, and the distortion management matrix may indicate a weighting factor to apply to a respective spatial layer of the plurality of spatial layers.

[0117] At 510, the UE 115-b may receive, from the network entity 105-c, a control message indicating to transmit an uplink message. In some cases, the proportion of NL distortion to allocate to each spatial layer of the plurality of spatial layers may be based on a quality of service of a data payload of the uplink message.

[0118] At 515, the UE 115-b may receive, from the network entity 105-c, an indication of a channel matrix associated with the uplink message.

[0119] At 520, the UE 115-b may receive, from the network entity 105-c, a control signal that indicates a quality of service indicator associated with the uplink message.

No. 2405667WO37

[0120] At 525, the UE 115-b may precode the uplink message to generate a precoded message for transmission via the plurality of spatial layers in accordance with the distortion management configuration. In some examples, the uplink message may be precoded based on the channel matrix.

[0121] At 530, the UE 115-b may determine a performance metric associated with the precoded message. In some cases, the performance metric may be determined for the plurality of spatial layers. In some examples, the performance metric may be an error vector magnitude metric or an out-of-band metric associated with each spatial layer of the plurality of spatial layers.

[0122] At 535, the UE 115-b may transmit, to the network entity 105-c, the precoded message via the plurality of spatial layers in accordance with the control message.

[0123] FIG. 6 shows a block diagram 600 of a device 605 that supports techniques for allocating NL distortion to spatial layers in accordance with one or more aspects of the present disclosure.

A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core,Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO73or 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.

[0274] 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.

[0275] Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium.

[0276] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of’ or “one or more of’) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on.”

[0277] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components,” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.”Attorney Docket No. PY2619.WO (114958.5636)Qualcomm Ref. No. 2405667WO75

[0278] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure), ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.

[0279] 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.

[0280] 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.

[0281] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure.
