[0002] The following relates to wireless communications, including information signaling for artificial intelligence or machine learning-based positioning or sensing.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. PB0009GR.WQ (114958.5251)Qualcomm Ref.

[0063] Some wireless communications systems may utilize one or more artificial intelligence or machine learning (AI / ML) models to perform one or more positioning or sensing procedures. Some AI / ML models used for AI / ML-based positioning or sensing procedures may correspond to a network setup (e.g., network settings, operating procedures, or physical arrangements, among other examples). Accordingly, explicit identification of AI / ML models for a network may be utilized to determine a network setup. It may be helpful to maintain confidentiality of network setup information for security or competitive reasons.

[0064] Some examples of the techniques described herein may allow communication of information to enable coordination of one or more AI / ML models for performing AI / ML-based positioning or sensing procedures while maintaining the confidentiality of network setup information. In some approaches, a wireless device (e.g., user equipment (UE)) or a network entity may communicate configuration information indicating that the wireless device is to communicate information indicative of a change to an AI / ML model for the AI / ML-based positioning or sensing procedure, information indicative of a condition of validity of an AI / ML model for the AI / ML- based positioning or sensing procedure, or information indicative of a group that includes an AI / ML model for the AI / ML-based positioning or sensing procedure. The information may be utilized to coordinate or control AI / ML model selection by signaling information that is non-unique to an AI / ML model (e.g., without specifically or explicitly indicating the AI / ML model).Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref.

[0065] Aspects of the disclosure are described in the context of wireless communications systems. Aspects of the disclosure are also described in the context of a wireless network structure. Aspects of the disclosure are further described in the context of a network architecture. Aspects of the disclosure are additionally described in the context of process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, flowcharts, a node diagram, and block diagrams that relate to information signaling for AI / ML-based positioning or sensing.

[0066] FIG. 1 shows an example of a wireless communications system 100 that supports information signaling for AI / ML-based positioning or sensing 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 nodes 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.

[0067] The network nodes 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 node 105 may be referred to as a network element, a network entity, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network nodes 105 and UEs 115 may wirelessly communicate via communication link(s) 125 (e.g., a radio frequency (RF) access link). For example, a network node 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network node 105 may establish the communication link(s) 125. The coverage area 110 may be an example of a geographic area over which a network node 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs).

[0068] 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, orAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO14 both at different times. The UEs 115 may be devices in different forms or have 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 nodes 105), as shown in FIG. 1.

[0069] As described herein, a node of the wireless communications system 100, which may be referred to as a network entity or a wireless node, may be a network node 105 (e.g., any network node 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 node 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 node 105, and the third node may be another UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network node 105, and the third node may be another network node 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 node 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network node 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 node 105 also discloses that a first node is configured to receive information from a second node.

[0070] In some examples, network nodes 105 may communicate with a core network 130, or with one another, or both. For example, network nodes 105 may communicate with the core network 130 via wired or wireless backhaul communication link(s) 120 (e.g., in accordance with an SI, N2, N3, or other interface protocol). In some examples, network nodes 105 may communicate with one another via backhaul communication link(s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network nodes 105) or indirectly (e.g., via the core network 130). In some examples, network nodes 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with aAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO15 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.

[0071] One or more of the network nodes 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 (AP), 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 node 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 node (e.g., a network node 105 or a single RAN node, such as a base station 140).

[0072] In some examples, a network node 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 nodes 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 node 105 may include one or more of a central unit (CU), such as a CU 160, a distributed unit (DU), such as a DU 165, a radio unit (RU), such as an RU 170, a RAN Intelligent Controller (RIC), such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission-reception point (TRP). One or more components ofAttorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref. No. 2406099WO16 the network nodes 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network nodes 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more of the network nodes 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)).

[0073] 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 be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., Fl interface, Fl-c interface, or Fl-u, among other examples), and a DU 165Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO17 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 nodes 105) that are in communication via such communication links.

[0074] 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 nodes 105 (e.g., network nodes 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 node 105 or base station 140 (such as a donor network node 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.

[0075] 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 donorAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO18 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.

[0076] 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.

[0077] For example, IAB node(s) 104 may be referred to as parent nodes that support communications for child IAB nodes, or may be referred to as child IAB nodes associated with IAB donors, or both. An IAB donor may include a CU 160 with a wired or wireless connection (e.g., backhaul communication link(s) 120) to the core network 130 and may act as a parent node to IAB node(s) 104. For example, the DU 165 of an IAB donor may relay transmissions to UEs 115 through IAB node(s) 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment via an Fl interface to IAB node(s) 104, and the IAB node(s) 104 may schedule transmissions (e.g., transmissions to the UEs 115Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO19 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.

[0078] 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 testing as described herein. For example, some operations described as being performed by a UE 115 or a network node 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).

[0079] 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.

[0080] 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 nodes 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.

[0081] The UEs 115 and the network nodes 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)Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO20125 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 node 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network node 105. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network node 105, may refer to any portion of a network node 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 nodes 105).

[0082] In some examples, such as in a carrier aggregation configuration, a carrier may have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN)) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non- standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different RAT).

[0083] The communication link(s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network node 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network node 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode).Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO21

[0084] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communications system 100 (e.g., the network nodes 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network nodes 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

[0085] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam), and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.

[0086] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (A ) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for aAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO 1 carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.

[0087] The time intervals for the network nodes 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■ Nf) 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 (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0088] 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.

[0089] 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)).

[0090] 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 multiplexingAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO23(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).

[0091] A network node 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network node 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)). In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network node 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.

[0092] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a network node 105 operating with lower power (e.g., a base station 140 operating with lower power) relative to a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. SmallAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO24 cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG), the UEs 115 associated with users in a home or office). A network node 105 may support one or more cells and may also support communications via the one or more cells using one or multiple component carriers.

[0093] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband loT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access for different types of devices.

[0094] In some examples, a network node 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 node (e.g., a network node 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 nodes 105). The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network nodes 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.

[0095] The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, network nodes 105 (e.g., base stations 140) may have similar frame timings, and transmissions from different network entities (e.g., different ones of the network nodes 105) may be approximately aligned in time. For asynchronous operation, network nodes 105 may have different frame timings, and transmissions from different network entities (e.g., different ones of network nodes 105) may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.

[0096] Some UEs 115, such as MTC or loT devices, may be relatively low cost or low complexity devices and may provide for automated communication betweenAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO25 machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network node 105 (e.g., a base station 140) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0097] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently). In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 may include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs)) within a carrier, within a guard-band of a carrier, or outside of a carrier.

[0098] 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 suchAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO26 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.

[0099] 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 node 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 node 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network node 105 or may be otherwise unable to or not configured to receive transmissions from a network node 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 node 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 node 105.

[0100] In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115). In some examples, vehicles may communicate using vehicle-to- everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network entities (e.g., network nodes 105, base stations 140, RUs 170) using vehicle-to- network (V2N) communications, or with both.

[0101] 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 coreAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO27(5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network nodes 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.

[0102] The wireless communications system 100 may include an location server 185 (e.g., LMF). The location server 185 may provide positioning, location, or tracking functions. For instance, the location server 185 may participate in one or more positioning procedures to determine a location of (e.g., coordinates of, relative distance(s) to, or an address of) one or more of the UEs 115. Examples of positioning procedures may include one or more operations of assisted global navigation satellite system (A-GNSS), observed time difference of arrival (OTDOA), enhanced cell identifier (E-CID), sensor-based positioning, wireless local area network (WLAN)- based positioning, Bluetooth-based positioning, terrestrial beacon systems (TBS) positioning, downlink time difference of arrival (DL-TDOA), downlink angle of departure (DL-AOD), multi-round-trip time (Multi-RTT), New Radio enhanced cell identifier (NR E-CID), uplink time difference of arrival (UL-TDOA), and uplink angle of arrival (UL-AOA), among other examples. Some examples of the positioning procedures may be managed by, assisted by, or performed with the location server 185. For instance, measurements associated with reference signaling may be provided to the location server 185, which may estimate a location of a UE 115 based on the measurements. In some aspects, the location server 185 may track or store location information corresponding to one or more UEs 115. Some examples of the positioning procedures may be performed without the location server 185.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO28

[0103] The location server 185 may be included in the core network 130 or may be separate from the core network 130. In some examples, a location server 185 may be a standalone device or may be included in (e.g., integrated with) a network node 105, a base station 140, a UE 115, a satellite 190, a server, or another device. For instance, the location server 185 may be (or may be included in) a secure user plane location (SUPL) location platform (SLP) device, a third-party server, or another device. The location server 185 may generally refer to a positioning device, a location device, a computing device, or a server, among other examples.

[0104] A UE 115 may communicate with the location server 185 directly or indirectly. For example, a UE 115 may communicate with the location server 185 via a network node 105 that is serving the UE 115 and via the core network 130. Additionally, or alternatively, a UE 115 may communicate with the location server 185 through another path (e.g., via an application server (not shown)) or via another network (e.g., via a WLAN AP), among other examples. Communication between a UE 115 and the location server 185 may be represented via an indirect connection (e.g., through a communication link 125, a network node 105, a communication link 155, a backhaul communication link 120, or the core network 130) or as a direct connection, with one or more intervening nodes (if any) omitted for concision or convenience.

[0105] A satellite 190 may be an aerial or space vehicle with signaling capability. In some examples, the wireless communications system 100 may include or communicate with one or more satellites 190. The satellite(s) 190 may be included in one or more satellite positioning systems (e.g., GNSS(s)). A satellite positioning system may include any combination of one or more global or regional navigation satellites associated with one or more satellite positioning systems (e.g., global positioning system (GPS), global navigation satellite system (GLONASS), BeiDou navigation satellite system (BDS), or Galileo, among other examples). A satellite positioning system may include satellites 190 or other transmitters positioned to enable receivers (e.g., UEs 115) to determine a location on or above the Earth based on signals (e.g., the signals 195) received from the satellites 190. For instance, each satellite 190 may transmit a signal 195 marked with a repeating pseudo-random noise (PN) code of a set quantity of chips. In some cases, one or more transmitters located on ground-based control stations, network nodes 105, or UEs 115 may transmit signals for enabling a UE 115 to determine a location.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO29

[0106] A UE 115 may include one or more receivers designed to receive the signal(s) 195 from the satellite(s) 190 for determining location information (e.g., a geographic location of the UE 115). For instance, the UE 115 may receive one or more signals 195 from the satellite(s) 190, which may be utilized to determine a location of the UE 115.

[0107] In a satellite positioning system, the use of signals 195 may be augmented with one or more satellite-based augmentation systems (SB AS) that may be associated with or enabled for use with one or more global or regional navigation satellite systems. An SB AS may provide integrity information, differential corrections, or other information for use in conjunction with a satellite positioning system. An SBAS may include one or more augmentation systems, such as the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS), the Multi-functional Satellite Augmentation System (MSAS), or the GPS Aided Geo Augmented Navigation (GAGAN) system, among other examples.

[0108] In some aspects, the satellite(s) 190 may be included in one or more nonterrestrial networks (NTNs). In an NTN, a satellite 190 may communicate with one or more devices (e.g., network entities, ground stations, NTN gateways, or gateways) located on or above the Earth. For example, the satellite 190 may send or receive one or more communications 192 with a network node 105. In some aspects, the communication(s) 192 may include one or more signals relayed to or from a UE 115. Additionally, or alternatively, the satellite 190 may communicate with another terrestrial device that is connected to one or more elements of the wireless communications system 100. For instance, the satellite 190 may communicate with a ground station or NTN gateway, which may provide access to the wireless communications system 100 or one or more other entities (e.g., Internet web servers or one or more other user devices) external to the wireless communications system 100. In some examples, a UE 115 may receive communication signals 195 from the satellite 190 instead of, or in addition to, communication signals from a terrestrial network entity.

[0109] 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 fromAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO30 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.

[0110] The wireless communications system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz, also known as the centimeter band, or using an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as the millimeter band. In some examples, the wireless communications system 100 may support millimeter wave (mmW) communications between the UEs 115 and the network nodes 105 (e.g., base stations 140, RUs 170), and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, such techniques may facilitate using antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.[OHl] The wireless communications system 100 may utilize licensed or 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 nodes 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. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO31

[0112] A network node 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network node 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 node 105 may be located at diverse geographic locations. A network node 105 may include an antenna array with a set of rows and columns of antenna ports that the network node 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.

[0113] The network nodes 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.

[0114] 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 node 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatialAttorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref. No. 2406099WO32 path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).

[0115] A network node 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network node 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network node 105 multiple times along different directions. For example, the network node 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network node 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network node 105.

[0116] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network node 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network node 105 or UE 115). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network node 105 along different directions and may report to the network node 105 anAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO33 indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.

[0117] In some examples, transmissions by a device (e.g., by a network node 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network node 105 to a UE 115). The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network node 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI- RS)), which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted along one or more directions by a network node 105 (e.g., a base station 140, an RU 170), a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device).

[0118] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network node 105), such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receiveAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO34 configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to- noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0119] 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 node 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.

[0120] The UEs 115 and the network nodes 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.

[0121] Some wireless communications systems may utilize one or more AI / ML models to perform one or more positioning or sensing procedures. AI / ML-based positioning or sensing may provide enhanced positioning accuracy in stringent NLOSAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO35 conditions. In some examples, a UE 115 may support one or more AI / ML models for positioning or sensing.

[0122] In some approaches, AI / ML model identification may be performed, which may include identifying an AI / ML model for shared information between a network entity and a UE. For instance, information identifying (e.g., specifically identifying or uniquely identifying) an AI / ML model may be shared during model identification. Functionality identification may include identifying a functionality of an AI / ML model for shared information between a network entity and a UE. For instance, information identifying (e.g., specifically identifying or uniquely identifying) a functionality of an AI / ML model may be shared during functionality identification.

[0123] In model identifier-based lifecycle management (LCM), one or more AI / ML models may be identified at a network, and the network or UE may activate, deactivate, select, or switch individual AI / ML models via model identifiers. For functionality identification, one or more functionalities may be defined within an AI / ML-enabled feature. Some approaches may determine or utilize a relationship between functionality identification and model identification.

[0124] Some approaches may attempt to achieve globality of AI / ML model identifiers. For example, globally unique AI / ML model identifiers may be utilized. Established (e.g., specified) or “hard-coded” globally unique AI / ML model identifiers, assigned globally unique AI / ML model identifiers, or other globally unique model identifiers may be utilized with an AI / ML model identifier structure. Accordingly, a UE or network (e.g., network entity, such as a location management function (LMF)) may identify potential AI / ML models or functionality in some approaches.

[0125] Some AI / ML models used for AI / ML-based positioning or sensing procedures may correspond to a network setup (e.g., network settings, operating procedures, or physical arrangements, among other examples). Accordingly, unique identification of AI / ML models for a network may be utilized to determine a network setup. It may be helpful to maintain confidentiality of network setup information for security or competitive reasons.

[0126] Some examples of the techniques described herein may allow communication of information to enable coordination of one or more AI / ML models forAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO36 performing AI / ML-based positioning or sensing procedures while maintaining the confidentiality of network setup information. In some approaches, a wireless device (e.g., UE 115) or a network entity (e.g., location server 185, LMF, or network node 105, among other examples) may communicate configuration information indicating that the wireless device is to communicate information indicative of a change to an AI / ML model for the AI / ML-based positioning or sensing procedure, information indicative of a condition of validity of an AI / ML model for the AI / ML-based positioning or sensing procedure, or information indicative of a group that includes an AI / ML model for the AI / ML-based positioning or sensing procedure. The information may be utilized to coordinate or control AI / ML model selection by signaling information that is nonunique to an AI / ML model (e.g., without specifically or explicitly indicating the AI / ML model).

[0127] As used herein, the terms “Al,” “AI / ML,” “Al-based,” or “ML-based” may refer to Al or machine learning techniques. The term “Al model” may refer to one or more Al models (with or without machine learning) or to one or more machine learning models. As used herein, an Al model may be referred to as an “Al-based model,” an “ML model,” or an “ML-based model.”

[0128] FIG. 2 shows an example of a network structure 200 that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. The wireless network structure 200 may include a core network 130-a, a RAN 225, a UE 115-a, an LMF 265, an external device 230 (e.g., third-party device or server), or an SLP 235. In some examples, the wireless network structure 200 may be included in the wireless communications system 100 described with reference to FIG. 1. The core network 130-a may be an example of the core network 130, the UE 115-a may be an example of the UEs 115, or the LMF 265 may be an example of the location server 185, as described with reference to FIG. 1.

[0129] The core network 130-a may provide one or more control plane (C-plane) functions (e.g., UE registration, authentication, network access, or gateway selection, among other examples) or one or more user plane (U-plane) functions (e.g., UE gateway function, data network access, or IP routing, among other examples). One or more of the functions of the core network 130-a may be implemented in one or more devices (e.g., one or more electronic devices, computing devices, servers, among other examples) inAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO37 hardware (e.g., circuitry) or a combination of hardware and instructions (e.g., a processor with instructions). The core network 130-a may be an EPC, 5GC, or a Next Generation Core (NGC), among other examples.

[0130] The core network 130-a may provide an AMF 210, a session management function (SMF) 220, or a user plane function (UPF) 215. The AMF 210 may provide one or more C-plane functions, such as registration management, connection management, reachability management, mobility management, lawful interception, transport for session management (SM) messages between one or more UEs 115-a and the SMF 220, transparent proxy services for routing SM messages, access authentication and access authorization, transport for short message service (SMS) messages between the UE 115-a and the short message service function (SMSF) (not shown in FIG. 2), or security anchor functionality (SEAF) (not shown in FIG. 2), among other examples. In some aspects, the AMF 210 may interact with an authentication server function (AUSF) (not shown in FIG. 2) and the UE 115-a, and may receive an intermediate key established as a result of a UE 115-a authentication process. In a case of authentication based on a universal mobile telecommunications system (UMTS) subscriber identity module (USIM), the AMF 210 may retrieve security information from the AUSF. In some examples, the AMF 210 may provide a security context management (SCM) function. The SCM function may receive a key from the SEAF that may be utilized to derive access-network specific keys. The AMF 210 may provide location services management for regulatory services, transport for location services messages between the UE 115-a and an LMF 265, transport for location services messages between the RAN 225 and the LMF 265, evolved packet system (EPS) bearer identifier allocation for interworking with the EPS, or UE 115-a mobility event notification. In some approaches, the AMF 210 may support one or more functionalities for Third Generation Partnership Project (3 GPP) access networks or non-3GPP access networks.

[0131] The UPF 215 may provide one or more U-plane functions, such as acting as an anchor point for intra / inter-RAT mobility, acting as an external protocol data unit (PDU) session point of interconnection to a data network (not shown in FIG. 2), providing packet routing and forwarding, packet inspection, user plane policy rule enforcement (e.g., gating, redirection, or traffic steering), user plane collection (e.g.,Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO38 interception), traffic usage reporting, quality of service (QoS) handling for the U-plane (e.g., uplink or downlink rate enforcement, reflective QoS marking in the downlink), uplink traffic verification (e.g., service data flow (SDF) to QoS flow mapping), transport level packet marking in the uplink or downlink, downlink packet buffering, downlink data notification triggering, or sending or forwarding one or more indications of an end of a transmission (e.g., “end markers”) to a source RAN node, among other examples. In some examples, the UPF 215 may support the transfer of location services messages over a U-plane between the UE 115-a and another device (e.g., the SLP 235 or the external device 230.

[0132] The SMF 220 may provide one or more functions, such as session management, UE IP address allocation and management, selection and control of user plane functions, configuration of traffic steering at the UPF 215 to route traffic to a destination, control (e.g., partial control) of policy enforcement or QoS, or downlink data notification. In some aspects, the SMF 220 may communicate with the AMF 210 over an N11 interface 240.

[0133] The RAN 225 may include one or more gNBs 255 or one or more ng-eNBs 260. The gNB(s) 255 or the ng-eNB(s) 260 may be examples of the network nodes 105 described with reference to FIG. 1. For instance, a next generation RAN (NG-RAN) may include one or more gNBs 255, or other examples of the RAN 225 may include one or more ng-eNBs 260 or gNBs 255.

[0134] The core network 130-a may communicate with the RAN 225 via a C-plane interface 245 (e.g., NG-C or N2 interface) or a U-plane interface 250 (e.g., NG-U or N3 interface). The C-plane interface 245 or the U-plane interface 250 may connect the gNB 255 or the ng-eNB 260 to the core network 130-a (e.g., to one or more control plane functions or one or more user plane functions). For instance, the C-plane interface 245 may connect the AMF 210 to one or more gNBs 255 or ng-eNBs 260 in the RAN 225, or the U-plane interface 250 may connect the UPF 215 to one or more gNBs 255 or ng- eNBs 260 in the RAN 225. The gNB(s) 255 or ng-eNB(s) 260 of the RAN 225 may communicate with each other via one or more backhaul communication links 120-a (e.g., Xn-C interface).

[0139] FIG. 3 shows an example of a network architecture 300 (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that supportsAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO41 information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. The network architecture 300 may illustrate an example for implementing one or more aspects of the wireless communications system 100. The network architecture 300 may include one or more CUs 160-b that may communicate directly with a core network 130-b via a backhaul communication link 120-b, or indirectly with the core network 130-b through one or more disaggregated network nodes 105 (e.g., a Near-RT RIC 175-b via an E2 link, or a Non-RT RIC 175-a associated with an SMO 180-a (e.g., an SMO Framework), or both). A CU 160-b may communicate with one or more DUs 165-b via respective midhaul communication links 162-b (e.g., an Fl interface). The DUs 165-b may communicate with one or more RUs 170-b via respective fronthaul communication links 168-b. The RUs 170-b may be associated with respective coverage areas 110-a and may communicate with UEs 115-b via one or more communication links 125-b. In some implementations, a UE 115-b may be simultaneously served by multiple RUs 170-b.

[0140] Each of the network nodes 105 of the network architecture 300 (e.g., CUs 160-b, DUs 165-b, RUs 170-b, Non-RT RICs 175-a, Near-RT RICs 175-b, SMOs 180-a, Open Clouds (O-Clouds) 305, Open eNBs (O-eNBs) 310) may include one or more interfaces or may be coupled with one or more interfaces configured to receive or transmit signals (e.g., data, information) via a wired or wireless transmission medium. Each network node 105, or an associated processor (e.g., controller) providing instructions to an interface of the network node 105, may be configured to communicate with one or more of the other network nodes 105 via the transmission medium. For example, the network nodes 105 may include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other network nodes 105. Additionally, or alternatively, the network nodes 105 may include a wireless interface, which may include a receiver, a transmitter, or transceiver (e.g., an RF transceiver) configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other network nodes 105.

[0141] In some examples, a CU 160-b may host one or more higher layer control functions. Such control functions may include RRC, PDCP, SDAP, or the like. Each control function may be implemented with an interface configured to communicate signals with other control functions hosted by the CU 160-b. A CU 160-b may beAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO42 configured to handle user plane functionality (e.g., CU-UP), control plane functionality (e.g., CU-CP), or a combination thereof. In some examples, a CU 160-b may be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface, such as an El interface when implemented in an O-RAN configuration. A CU 160-b may be implemented to communicate with a DU 165-b, as necessary, for network control and signaling.

[0142] A DU 165-b may correspond to a logical unit that includes one or more functions (e.g., base station functions, RAN functions) to control the operation of one or more RUs 170-b. In some examples, a DU 165-b may host, at least partially, one or more of an RLC layer, a MAC layer, and one or more aspects of a PHY layer (e.g., a high PHY layer, such as modules for FEC encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3rd Generation Partnership Project (3GPP). In some examples, a DU 165-b may further host one or more low PHY layers. Each layer may be implemented with an interface configured to communicate signals with other layers hosted by the DU 165-b, or with control functions hosted by a CU 160-b.

[0143] In some examples, lower-layer functionality may be implemented by one or more RUs 170-b. For example, an RU 170-b, controlled by a DU 165-b, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like), or both, based at least in part on the functional split, such as a lower-layer functional split. In such an architecture, an RU 170-b may be implemented to handle over the air (OTA) communication with one or more UEs 115-b. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 170-b may be controlled by the corresponding DU 165-b. In some examples, such a configuration may enable a DU 165-b and a CU 160-b to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0144] The SMO 180-a may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network nodes 105. For non-virtualized network nodes 105, the SMO 180-a may be configured to support the deployment ofAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO43 dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (e.g., an 01 interface). For virtualized network nodes 105, the SMO 180-a may be configured to interact with a cloud computing platform (e.g., an O-Cloud 305) to perform network node life cycle management (e.g., to instantiate virtualized network nodes 105) via a cloud computing platform interface (e.g., an 02 interface). Such virtualized network nodes 105 can include, but are not limited to, CUs 160-b, DUs 165-b, RUs 170-b, and Near-RT RICs 175-b. In some implementations, the SMO 180-a may communicate with components configured in accordance with a 4G RAN (e.g., via an 01 interface). Additionally, or alternatively, in some implementations, the SMO 180-a may communicate directly with one or more RUs 170-b via an 01 interface. The SMO 180-a also may include a Non- RT RIC 175-a configured to support functionality of the SMO 180-a.

[0145] The Non-RT RIC 175-a may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence (Al) or machine learning (ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 175-b. The Non-RT RIC 175-a may be coupled with or communicate with (e.g., via an Al interface) the Near-RT RIC 175-b. The Near-RT RIC 175-b may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (e.g., via an E2 interface) connecting one or more CUs 160-b, one or more DUs 165-b, or both, as well as an O-eNB 310, with the Near-RT RIC 175-b.

[0146] In some examples, to generate AI / ML models to be deployed in the Near-RT RIC 175-b, the Non-RT RIC 175-a may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 175-b and may be received at the SMO 180-a or the Non-RT RIC 175-a from nonnetwork data sources or from network functions. In some examples, the Non-RT RIC 175-a or the Near-RT RIC 175-b may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 175-a may monitor long-term trends and patterns for performance and employ Al or ML models to perform corrective actions through the SMO 180-a (e.g., reconfiguration via 01) or via generation of RAN management policies (e.g., Al policies).Attorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref.

[0147] FIG. 4 shows an example of a wireless communications system 400 that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. The wireless communications system 400 may implement aspects of or may be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 400 includes a wireless device 415, which may be an example of a UE 115, network node 105, RU 170, DU 165, or CU 160 described with reference to FIG. 1, a UE 115-a, gNB 255, RU 170-a, DU 165-a, CU 160-a, or ng-eNB 260 described with reference to FIG. 2, or a UE 115-b, RU 170-b, DU 165-b, or CU 160-b described with reference to FIG. 3. The wireless communications system 400 also includes network entity 405, which may be an example of a network node 105, location server 185, RU 170, DU 165, or CU 160 described with reference to FIG. 1, a UE 115-a, LMF 265, external device 230, SLP 235, AMF 210, SMF 220, UPF 215, gNB 255, RU 170-a, DU 165-a, CU 160-a, or ng-eNB 260 described with reference to FIG. 2, or a UE 115-b, RU 170-b, DU 165-b, or CU 160-b described with reference to FIG. 3. In some examples, the network entity 405 may be an example of an sensing management function (SeMF) (e.g., a device, such as a server, for performing one or more operations related to sensing), which may be included in a core network or may be separate from a core network.

[0148] The wireless device 415 may communicate with the network entity 405 using a link 425, which may be an example of a communication link 125, a backhaul communication link 120, or a communication link 155 described with reference to FIG. 1, a communication link 125-a, a backhaul communication link 120-a, a C-plane interface 245, or a U-plane interface 250 described with reference to FIG. 2, a communication link 125-b or a backhaul communication link 120-b described with reference to FIG. 3, or another link. The link 425 may include a uni-directional or bidirectional link that enables uplink, downlink, sidelink, device-to-device, or other communications. For example, the wireless device 415 may transmit one or more transmissions, such as control signals or data signals, to the network entity 405 using the link 425, or the network entity 405 may transmit one or more transmissions 410, such as control signals or data signals, to the wireless device 415 using the link 425. The transmission(s) may include one or more uplink transmissions, downlink transmissions, sidelink transmissions, or other transmissions.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO45

[0149] In some approaches, the wireless device 415 (e.g., a UE) may be capable of performing one or more positioning procedures to generate position information. A positioning procedure may be one or more operations for estimating or sensing a position of an object (e.g., a device such as the wireless device 415 or a UE, or a passive object that does not provide signals for positioning) or an object. As used herein, a “positioning procedure” or a “positioning or sensing procedure” may include one or more operations for sensing or estimating a position of an object.

[0150] For instance, a positioning procedure may include one or more operations of A-GNSS positioning, OTDOA positioning, E-CID positioning, sensor-based positioning (e.g., monostatic mode(s), bi-static mode(s), or multi-static mode(s)), WLAN-based positioning, Bluetooth-based positioning, TBS positioning, DL-TDOA positioning, DL- AOD positioning, Multi-RTT positioning, NR E-CID positioning, UL-TDOA positioning, or UL-AOA positioning, among other examples. Position information may include an estimated position (e.g., estimated location) or one or more measurements associated with a positioning procedure (e.g., AI / ML-based positioning procedure or non-AI / ML-based positioning procedure). For instance, position information may include a position or measurement determined based on one or more positioning procedures, such as A-GNSS positioning, OTDOA positioning, E-CID positioning, sensor-based positioning (e.g., monostatic mode(s), bi-static mode(s), or multi-static mode(s)), WLAN-based positioning, Bluetooth-based positioning, TBS positioning, DL-TDOA positioning, DL-AOD positioning, Multi-RTT positioning, NR E-CID positioning, UL-TDOA positioning, or UL-A positioning, among other examples.Examples of positioning or sensing procedures are described with reference to FIG. 23, FIG. 25A, FIG. 25B, FIG. 26, or FIG. 27.

[0151] As used herein, the term “AI / ML-based positioning or sensing procedure” may refer to a positioning procedure or a sensing procedure performed with an Al model or ML model. An “AI / ML-based positioning or sensing procedure” may refer to direct AI / ML (D-AI / ML) positioning or sensing, or may refer to assisted AI / ML (A- AI / ML) positioning or sensing. An “AI / ML model” for positioning may refer generally to a physical AI / ML model, a logical AI / ML model, an AI / ML function, AI / ML functionality, or an AI / ML method, among other examples. The term “non-AI / ML- based positioning or sensing procedure” may refer to a positioning procedure or aAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO46 sensing procedure performed without an Al model or ML model. AI / ML-based positioning or sensing procedures may improve positioning accuracy.

[0152] A non-AI / ML-based positioning or sensing procedure may include one or more positioning procedures or one or more sensing procedures where an AI / ML technique is not utilized to determine (e.g., infer or predict) a location or measurement. For instance, A-GNSS positioning, OTDOA positioning, E-CID positioning, sensorbased positioning, WLAN-based positioning, Bluetooth-based positioning, TBS positioning, DL-TDOA positioning, DL-AOD positioning, Multi-RTT positioning, NR E-CID positioning, UL-TDOA positioning, UL-AOA positioning, or other positioning or sensing performed without the use of an AI / ML technique or model may be examples of a non-AI / ML-based positioning or sensing procedure.

[0153] An AI / ML-based positioning or sensing procedure may include one or more positioning procedures or one or more sensing procedures where one or more AI / ML techniques (e.g., AI / ML model(s) or AI / ML function(s)) are utilized to determine (e.g., infer or predict) a position or measurement. In some examples, an Al model may be utilized to perform one or more operations of a positioning procedure (e.g., to infer or predict a measurement, value, quantity, or location). For instance, A-GNSS positioning, OTDOA positioning, E-CID positioning, sensor-based positioning (e.g., monostatic mode(s), bi-static mode(s), or multi-static mode(s)), WLAN-based positioning, Bluetooth-based positioning, TBS positioning, DL-TDOA positioning, DL-AOD positioning, Multi-RTT positioning, NR E-CID positioning, UL-TDOA positioning, UL-AOA positioning, or other positioning or sensing performed with the use of an AI / ML technique(s) or model(s) may be examples of an AI / ML-based positioning or sensing procedure. For instance, an Al model may be trained to model one or more operations of a positioning procedure or a sensing procedure. When the Al model is executed, for instance, a position or one or more measurements may be generated (e.g., inferred or predicted) without directly performing the one or more operations of the positioning procedure or the sensing procedure.

[0154] A position may be information or data indicating a point, area, or region where an object (e.g., the wireless device 415, another device, a vehicle, a passive object, a road, a sign, a traffic signal, a rock, a tree, a building, or a person, among other examples) is located. A location may be expressed as coordinates (e.g., latitude,Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO47 longitude, or altitude of a geographic coordinate system (GCS), universal transverse mercator (UTM) coordinates, state plane coordinate system (SPCS) coordinates, or Earth-centered Earth-fixed (ECEF) coordinates, among other examples), an address, or a location relative to another location, among other examples.

[0155] A measurement may be measured, sensed, generated, calculated, inferred, or predicted based on one or more samples, sensor data, information, or characteristics of a reference signal. Examples of measurements may include signal strength, reference signal received power (RSRP), reference signal received path power (RSRPP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), signal-to- interference plus noise ratio (SINR), SNR, channel frequency response (CFR), channel impulse response (CIR), power delay profile (PDP), delay profile (DP), channel quality indicator (CQI), CSI, line-of-sight (LOS) indicator, time of arrival (TOA), angle of arrival (AO A), angle of departure (AOD), round-trip time (RTT), reference signal time difference (RSTD), time difference of arrival (TDOA), reference signal carrier phase (RSCP), reference signal carrier phase difference (RSCPD), reception-to-transmission (Rx-Tx) time difference, range, distance, image data, temperature data, or motion data, among other examples. In some examples, a measurement may be data or an indicator that indicates one or more of the aforementioned values.

[0156] In some examples, a network node may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive), a reference signal (not shown in FIG. 4). In some examples, the network node may be a positioning reference unit (PRU). The reference signal may be a signal (e.g., electromagnetic signal, RF signal) with one or more established characteristics (e.g., signaling pattern, strength, amplitude, magnitude, frequency, timing, modulation, phase, or data, among other examples). For instance, the wireless device 415 or the network entity 405 may store information indicating one or more of the characteristics of the reference signal, which may allow for comparison of one or more stored characteristics and one or more characteristics of the received reference signal. The reference signal (e.g., the comparison) may enable channel estimation (e.g., channel attenuation, phase, frequency shift, or Doppler effects, among other examples), positioning, or tracking. Examples of the reference signal may include a reference signal of a synchronization signal block (SSB), a CSLRS, a positioningAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO48 reference signal (PRS), a sounding reference signal (SRS), a demodulation reference signal (DMRS), or a tracking reference signal (TRS), among other examples.

[0157] In some examples, the wireless device 415 may obtain, receive, sense, capture, or generate one or more measurements. For instance, the wireless device 415 may include, may communicate with, or may be coupled with one or more sensors to obtain one or more measurements. Examples of a sensor may include an image sensor(s), infrared (IR) sensor(s), light sensor(s), depth sensor(s) (e.g., LIDAR, stereoscopic camera(s), or time-of-flight (TOF) sensor(s)), microphone(s), or RF sensor(s), among other examples. Examples of one or more measurements may include a range map (e.g., depth map), Doppler map, space map, angle map, light spectrum data, pixel(s), image(s) (e.g., red-green-blue-depth (RGBD) image(s)), audio signal(s), temperature map, TOF measurement(s), RF measurement s), or other information (e.g., information regarding one or more objects).

[0158] The measurement s) may be processed to generate input (e.g., input data) to an AI / ML model or may be utilized by an AI / ML model to generate an inferred position or other measurements. Examples of input data, inferred measurements, and positions (e.g., locations) are provided with reference to FIG. 25 A and FIG. 25B. In some aspects, an indication of one or more measurements or positions (e.g., one or more inferred measurements or positions) may be communicated with (e.g., transmitted to or received from) the wireless device 415 or the network entity 405. For example, the wireless device 415 may output (e.g., transmit) or the network entity 405 may obtain (e.g., receive) an indication of one or more inferred measurements or positions based on the one or more processing operations associated with AI / ML. Some examples of the techniques described herein may be utilized for AI / ML-based positioning for sensing, for which position, range, velocity, or angle of an object (e.g., a passive object or device) may be an AI / ML model output.

[0159] In some examples, one or more AI / ML models or one or more portions of one or more AI / ML models may be stored or processed on the wireless device 415 (e.g., a UE or network node) or on the network entity 405 (e.g., a UE, a network node, location server, or sensing server). Examples of locations where an AI / ML model may be stored or processed are provided with reference to FIG. 26.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO49

[0160] The network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive) first configuration information 440 indicating that the wireless device 415 is to participate in an AI / ML-based positioning or sensing procedure. For instance, the first configuration information 440 may include a code, a bit, a value, a signal, or other information indicating that the wireless device 415 is to perform one or more operations included in an AI / ML-based positioning or sensing procedure. In some aspects, the first configuration information 440 may indicate an instruction, command, or request for the wireless device 415 to collect or sense one or more measurements for use by an AI / ML model to infer one or more measurements or a position of an object. Additionally, or alternatively, the first configuration information 440 may indicate an instruction, command, or request for the wireless device 415 to execute one or more AI / ML models to generate a position (e.g., position estimate) or measurements. In some examples, the first configuration information 440 may be communicated (e.g., output, transmitted, obtained, or received) via TRP information, downlink control information (DCI), an RRC message, a medium access control-control (MAC-CE) message, LTE positioning protocol (LPP) signaling, NR positioning protocol A (NRPPa) signaling, or sidelink LPP (SL-LPP) signaling, among other examples.

[0161] The network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive), second configuration information 445 related to an AI / ML model. In some examples, the second configuration information 445 may be communicated (e.g., output, transmitted, obtained, or received) via TRP information, DCI, an RRC message, a MAC-CE message, LPP signaling, NRPPa signaling, or SL- LPP signaling, among other examples. In some aspects, the second configuration information 445 may be communicated with the first configuration information 440 (e.g., in a same message) or may be communicated separately from the first configuration information 440.

[0162] In some approaches, the second configuration information 445 may indicate that the wireless device 415 is to communicate (e.g., output, transmit, obtain, or receive) first data indicative of a change to the AI / ML model for the AI / ML-based positioning or sensing procedure, second data indicative of a condition of validity of the AI / ML model for the AI / ML-based positioning or sensing procedure, or third data indicative of aAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO50 group that includes the AI / ML model for the AI / ML-based positioning or sensing procedure.

[0163] The wireless device 415 may communicate (e.g., output, transmit, obtain, or receive) the first data, the second data, or the third data. For example, the wireless device 415 may output (e.g., transmit) the first data, the second data, or the third data to the network entity 405 or to one or more other devices (e.g., one or more other wireless devices). In some aspects, the network entity 405 may communicate (e.g., output, transmit, obtain, or receive) the first data, the second data, or the third data.

[0164] In some examples, the first data may comprise or indicate a new model indicator associated with one or more AI / ML models (or one or more AI / ML model identifiers, for instance). For instance, the first data may indicate whether an AI / ML model utilized for an AI / ML-based positioning or sensing procedure has been changed (by the wireless device 415, the network entity 405, or another device, for example). In some aspects, if a device (e.g., the wireless device 415, a UE, the network entity 405, or a gNB, among other examples) is not allowed to report whether a specific AI / ML model is being used, the device may support the indication of whether the AI / ML model has changed or not.

[0165] In some approaches, the first data may include a bit with a value indicative of a change to the AI / ML model or a bit with a change in value indicative of the change to the AI / ML model. For instance, the first data may be formatted as a new model indicator bit. In some aspects, the bit may be a toggle bit, where a change in the value of the bit relative to a previous communication (e.g., report) indicates that a different or new AI / ML model is being utilized. If the bit maintains the same value relative to a previous communication, the same AI / ML model may still be utilized. In some examples, the bit may be a change indication bit, where a value of the bit (e.g., 1) may indicate that a different or new model is being utilized.

[0166] In some aspects, the first data may indicate a change to a layer of the AI / ML model, a change to a structure of the AI / ML model, a change to one or more weights of the AI / ML model, or any combination thereof. For example, if the wireless device 415 or the network entity 405 has information indicating a structure of the AI / ML model, the first data may indicate (e.g., may have a format) that a layer of the AI / ML model hasAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO51 changed or may indicate which layer of the AI / ML model that has changed. Additionally, or alternatively, the first data may allow (e.g., may have a format that allows) the wireless device 415 or the network entity 405 to signal that the structure of the AI / ML model has changed (e.g., the structure has changed from a 2-layer model to a 3 -layer model), or that the weights of one or more layers have changed (with or without the structure changing), or a combination thereof. For example, a structure of an AI / ML model may refer to one or more layers, nodes, or connections of the AI / ML model, where a change to the structure of the AI / ML model may indicate an addition of one or more layers, nodes, or connections of the AI / ML model, or may indicate a removal of one or more layers, nodes, or connections of the AI / ML model. A change to a weight of the AI / ML model may refer to an increase or decrease to a weight associated with one or more layers, nodes, or connections of the AI / ML model.

[0167] In some approaches, the first data may indicate a time associated with the change to the AI / ML model. For instance, the first data may indicate a time of a change from one AI / ML model to another AI / ML model, or may indicate a time range during which an AI / ML model was utilized or active. For instance, the first data may indicate that a first AI / ML model (e.g., “Ml”) was utilized from a first time stamp (e.g., time stamp 1) to a second time stamp (e.g., time stamp 2), may indicate that a second AI / ML model (e.g., “M2”) was utilized from the second time stamp (e.g., time stamp 2) to a third time stamp (e.g., time stamp 3), and may indicate that the first AI / ML model (e.g., “Ml”) was utilized from the third time stamp (e.g., time stamp 3) to a fourth time stamp (e.g., time stamp 4). In some examples, the first data (e.g., report) may include one or more identifiers (e.g., “Ml” and “M2”) associated with one or more AI / ML models. The one or more identifiers may not uniquely identify the AI / ML model(s). For instance, the identifier(s) may be utilized to generally indicate changes for AI / ML models, but may not specifically or uniquely identify the AI / ML model(s).

[0168] In some examples, the first data may be included in a model change report or may be included in a report corresponding to a higher layer (e.g., a higher layer than a physical layer). In some aspects, the first data (e.g., model change report or higher layer report) may be communicated via LPP signaling.

[0169] In some approaches, the wireless device 415 may output (e.g., transmit), or the network entity 405 may obtain (e.g., receive), capability information indicating aAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO52 capability of the wireless device 415 to communicate the first data indicative of the change to the AI / ML model. For instance, the capability information may indicate whether the wireless device 415 (e.g., UE) supports indicating a change (e.g., a new model indicator) to an AI / ML model or not. In some aspects, the wireless device 415 may output (e.g., transmit), or the network entity 405 may obtain (e.g., receive), capability information indicating whether the wireless device 415 supports reporting a change (e.g., new model indicator) for a specific functionality of an AI / ML model or for a specific procedure.

[0170] The first data indictive of a change to an AI / ML model may be useful to indicate a change to an AI / ML model to allow coordination of the AI / ML model between the wireless device 415 and the network entity 405 without uniquely identifying the AI / ML model. For instance, without signaling of which AI / ML model is being utilized or an indication of a change to the AI / ML model, a receiver (e.g., network entity 405) of a report (e.g., measurement report) may not have information indicating whether the same AI / ML model is being utilized across different measurement occasions.

[0171] In some approaches, the wireless device 415 or the network entity 405 may communicate (e.g., output, transmit, obtain, or receive) the second data indicative of the condition of validity of the AI / ML model for the AI / ML-based positioning or sensing procedure. In some examples, the condition of validity includes or indicates a quantity of time in which the AI / ML model is valid for the AI / ML-based positioning or sensing procedure. For example, the quantity of time may indicate a time window or an expiration time for a validity timer in which an AI / ML model may be utilized for an AI / ML-based positioning or sensing procedure. For instance, a validity timer may indicate an amount of time for which an AI / ML model may be valid.

[0172] In some aspects, the wireless device 415 or the network entity 405 may determine a second AI / ML model for the AI / ML-based positioning or sensing procedure based on an expiration of the quantity of time in which the AI / ML model is valid. After timer expiration, for example, the wireless device 415 (e.g., UE) or the network entity 405 (e.g., LMF) may perform (e.g., repeat, reapply, or perform again) an AI / ML model identification procedure to select an AI / ML model for an AI / ML-based positioning or sensing procedure. In some cases, defining the AI / ML model uniquenessAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO53 for all potential use cases may be challenging. A time window or expiration time may be flexibly utilized for a variety of use cases.

[0173] In some examples, the condition of validity may include a quantity of time in which a group of AI / ML models (that includes the AI / ML model, for example) is valid for the AI / ML-based positioning or sensing procedure. For instance, an AI / ML model group identifier (e.g., code, name, string, or pattern, among other examples) may be utilized. An AI / ML model group identifier may be unique to (e.g., specific to) an AI / ML model group. The AI / ML model group identifier may not uniquely or specifically identify an AI / ML model in the AI / ML model group. In some aspects, the AI / ML model group identifier may be associated with a validity timer. An AI / ML model group (e.g., AI / ML model group identifier) may be determined (e.g., reevaluated or communicated) after expiration of the validity timer. If the AI / ML model group is validated, the same AI / ML model (that is included in the current AI / ML model group with the associated AI / ML model group identifier) may continue to be utilized. If the AI / ML model group is invalidated (e.g., if the validity timer for the AI / ML model group expires), the wireless device 415 (e.g., UE) or the network entity 405 (e.g., LMF) may validate a group of AI / ML models (e.g., all the AI / ML models), or may obtain a new AI / ML model group identifier (or may utilize a different AI / ML model, for instance).

[0174] In some examples, the condition of validity may include or indicate an area in which the AI / ML model is valid for the AI / ML-based positioning or sensing procedure. For instance, an AI / ML model may be valid or utilized within the area (e.g., validity area).

[0175] In some aspects, the wireless device 415 or the network entity 405 may determine a second AI / ML model for the AI / ML-based positioning or sensing procedure based on an exit of the wireless device 415 from the area in which the AI / ML model is valid. For instance, if the wireless device 415 crosses a boundary of the area, the wireless device 415 (e.g., UE) or the network entity (e.g., LMF) may perform (e.g., repeat, reapply, or perform again) an AI / ML model identification procedure to select an AI / ML model for an AI / ML-based positioning or sensing procedure.

[0176] Some examples of the AI / ML model identification window (e.g., validity timer or area validity) may be applicable to one or more model identificationAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO54 procedures. For instance, if a validity timer expires or the wireless device 415 (e.g., UE) leaves an area in which an AI / ML model is valid, the network entity 405 (e.g., an LMF or another network entity 405) may validate (e.g., transfer or indicate the validity of) one or more AI / ML models.

[0177] In some approaches, the wireless device 415 or the network entity 405 may communicate (e.g., output, transmit, obtain, or receive) the third data indicative of a group that includes the AI / ML model for the AI / ML-based positioning or sensing procedure. For instance, AI / ML models may be grouped for identification or an AI / ML group may be identified. In some aspects, the wireless device 415 (e.g., UE) or the network entity 405 (e.g., gNB or LMF) may identify the AI / ML models at a group level (e.g., only at a group level). For example, the wireless device 415 or the network entity 405 may utilize (e.g., may only utilize) AI / ML models that belong to a group (e.g., one group). Additionally, or alternatively, the network entity 405 (e.g., LMF) may request the wireless device 415 to utilize (e.g., to only utilize) AI / ML models belonging to a group (e.g., one group). Signaling information at a group level may reduce signaling (e.g., overhead signaling).

[0178] In some examples, the third data may indicates at least one attribute (e.g., one or more conditions) shared by AI / ML models included in the group. For instance, AI / ML models may be grouped based on one or more attributes (e.g., conditions). In some approaches, the at least one attribute shared by the AI / ML models included in the group may be (or may include) a positioning or sensing procedure type (e.g., positioning method), an input, an output, an AI / ML model structure, an AI / ML model size (e.g., quantity of nodes, layers, connections, inputs, or outputs, among other examples), an AI / ML model computation complexity, a condition of validity, a bandwidth (e.g., a supported bandwidth or quantity of processing supported by the AI / ML models in a period of time), a quantity of time of validity (e.g., time for validity timer expiration), or an area of validity.

[0179] In some approaches, the third data may be communicated in a request for assistance data. For instance, the wireless device 415 may output (e.g., transmit), or the network entity 405 may obtain (e.g., receive) a request for assistance data. The request for assistance data (or a message that includes the request for assistance data, for instance) may include the third data. In some aspects, the third data may include orAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO55 indicate group information (e.g., information indicating or identifying a group of AI / ML models) may be provided as part of the request for assistance data.

[0180] In some examples, the wireless device 415 may select an AI / ML model for the AI / ML-based positioning or sensing procedure based on the at least one attribute (e.g., condition(s)) or a capability of the wireless device 415. For instance, the wireless device 415 (e.g., UE) may determine (e.g., select) an AI / ML model based on a positioning or sensing procedure type (e.g., positioning method) requested or one or more capabilities of the wireless device 415. In some approaches, the network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive) a request or configuration information for the wireless device 415 to perform an AI / ML- based positioning or sensing procedure of a positioning or sensing procedure type. Examples of types of positioning or sensing procedures are provided with reference to FIG. 23 or FIG. 27.

[0181] In some examples, the wireless device 415 or the network entity 405 may communicate (e.g., output, transmit, obtain, or receive) information associated with at least one attribute shared by at least two groups of AI / ML models. The information may indicate whether the at least two groups of AI / ML models share the at least one attribute, may indicate a relationship between the at least two groups of AI / ML models based at least in part on the at least one attribute, may indicate a hierarchical structure of the at least two groups of AI / ML models, or may indicate any combination thereof. For one or more of the identification techniques described herein, for instance, AI / ML model groups may have an assigned relation information or indicator. In some aspects, the relation information or indicator may indicate whether two or more AI / ML model groups share one or more settings or conditions, may indicate a relationship between two or more model groups regarding their settings or conditions, or may indicate a hierarchical structure (e.g., relationship) between group models (e.g., between root or parent group models and child group models). Examples of attributes shared between AI / ML model groups are provided with reference to FIG. 5.

[0182] In some approaches, the network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive), an indication that the wireless device 415 is to transmit information indicating an AI / ML model assignment to one or more wireless devices. For instance, the wireless device 415 may operate in an “anchor” role,Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO56 where the wireless device 415 may transmit an AI / ML model assignment to one or more other wireless devices. A wireless device 415 in the anchor role may assigning an identifier of a group of AI / ML models to one or more wireless devices (e.g., all UEs) within a set of wireless devices. In some aspects, a wireless device 415 in the anchor role (e.g., an anchor UE) may be identified or assigned by the network entity 405 (e.g., LMF). The network entity 405 (e.g., LMF) may output (e.g., transmit or provide) information (e.g., identity information) of the wireless device 415 in the anchor role to one or more wireless devices (e.g., all UEs) in a set of wireless devices. Examples of anchor UEs are provided with reference to FIG. 6.

[0183] In some approaches, the wireless device 415 may output (e.g., transmit), to one or more wireless devices, information indicating an AI / ML model assignment for performing one or more AI / ML-based positioning or sensing procedures corresponding to the one or more wireless devices. For instance, the wireless device 415 may operate as an anchor UE for AI / ML model assignments.

[0184] In some examples, the wireless device 415 may determine, based on a property of the wireless device 415, that the wireless device 415 is to transmit the information indicating the AI / ML model assignment to the one or more wireless devices. For instance, one or more wireless devices (e.g., one or more or all UEs in a set of UEs) may determine a wireless device with the anchor role (e.g., an anchor UE) based on the one or more (e.g., different) capabilities of the wireless device(s). For instance, the wireless device 415 (or multiple wireless devices) may determine (e.g., negotiate or select) a wireless device for the anchor role based on a processing capability (e.g., processing capabilities of multiple UEs), based on a hardware capability (e.g., hardware capabilities of multiple UEs), based on battery status (e.g., battery statuses of multiple UEs), or based on whether a wireless device 415 is stationary or mobile, among other examples. For instance, the wireless device 415 may communicate information (e.g., one or more indications of a capability(ies), battery status(es), or mobility status(es) with one or more other wireless devices. In some aspects, a wireless device with a greatest processing capability, greatest hardware capability, greatest battery charge, a stationary status, or a combination thereof (e.g., weighted or unweighted combination of factors) may be determined as a wireless device with the anchor role.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO57

[0185] In some approaches, a wireless device with the anchor role (e.g., an anchor UE) may change periodically or based on an event trigger. Examples of event triggers may include when a battery charge is below a threshold, operating at a processing load (e.g., average processing load) that is greater than a threshold, or other events. In some aspects, a wireless device 415 with the anchor role (e.g., an anchor UE) may communicate with one or more other wireless devices to request (e.g., suggest or propose) or instruct one or more of the other wireless devices to change the AI / ML model.

[0186] FIG. 5 shows examples of block diagrams 500 that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. The block diagrams 500 illustrate examples of instances (e.g., a first instance 505-a, a second instance 505-b, and a third instance 505-c) of relationships between groups of AI / ML models in accordance with some examples of the technique described herein. The groups of AI / ML models described with reference to FIG. 5 may be examples of the groups of AI / ML models described with reference to FIG. 4. In some aspects, one or more of the AI / ML models described herein reference to FIG. 5 may be implemented as described with reference to FIG. 4 or FIG. 24. While the groups of AI / ML models illustrated in FIG. 5 each include three AI / ML models, one or more groups of different quantities of AI / ML models may be utilized in accordance with the techniques described herein.

[0187] As described herein, information may be communicated between a wireless device 415 and a network entity 405, wherein the information is associated with at least one attribute shared by at least two groups of AI / ML models. The information may indicate whether the at least two groups of AI / ML models share the at least one attribute, may indicate a relationship between the at least two groups of AI / ML models based at least in part on the at least one attribute, or may indicate a hierarchical structure of the at least two groups of AI / ML models. Examples of the relationship (e.g., shared attribute(s)) may include a shared validity area (e.g., where the validity areas are the same, or where validity areas differ in size and one validity area is located within a shared region of another validity area), a shared validity timer (e.g., where the validity timers are the same, or where validity timers differ in duration and one validity timer overlaps in time with another validity timer), or a shared bandwidth (e.g., where theAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO58 bandwidths are the same, or where bandwidths differ and one bandwidth is included within another bandwidth), among other examples.

[0188] In the first instance 505-a, a first group 510-a includes AI / ML models 515-a, 515-b, and 515-c, and a second group 510-b includes AI / ML models 515-d, 515-e, and 515-f. The first group 510-a and the second group 510-b have a shared bandwidth attribute 520. For instance, each of the AI / ML models 515-a, 515-b, and 515-c of the first group 510-a may have the shared bandwidth attribute 520 with the AI / ML models 515-d, 515-e, and 515-f of the second group 510-b.

[0189] In the second instance 505-b, a third group 510-c includes AI / ML models 515-g, 515-h, and 515-i, and a fourth group 510-d includes AI / ML models 515-j, 515-k, and 515-1. The third group 510-c and the fourth group 510-d have a shared area attribute 525. For instance, each of the AI / ML models 515-g, 515-h, and 515-i of the third group 510-c may have the shared area attribute 525 with the AI / ML models 515-j, 515-k, and 515-1 of the fourth group 510-d. In this example, the supported validity area of the third group 510-c may be larger than (e.g., may overlap with or include) the supported validity area of the fourth group 510-d.

[0190] In the third instance 505-c, AI / ML models 515-m, 515-n, 515-o, 515-p, 515-q, 515-r, 515-s, 515-t, 515-u, 515-v, 515-w, and 515-x, are grouped in accordance with a hierarchical structure. For example, a root group 530 may include the AI / ML models 515-m, 515-n, 515-o, 515-p, 515-q, 515-r, 515-s, 515-t, 515-u, 515-v, 515-w, and 515-x, which each share an attribute (e.g., validity area). The root group 530 may include a fifth group 535, a sixth group 540, a seventh group 545, and an eighth group 550. The fifth group 535, sixth group 540, seventh group 545, and eighth group 550 may be child groups of the root group 530. The fifth group 535 includes AI / ML models 515-m, 515-n, and 515-o; the sixth group 540 includes AI / ML models 515-p, 515-q, and 515-r; the seventh group 545 includes AI / ML models 515-s, 515-t, and 515-u; and the eighth group 550 includes AI / ML models 515-v, 515-w, and 515-x. The AI / ML models 515-m, 515-n, and 515-o of the fifth group 535 may share a positioning or sensing procedure type (e.g., DL-TDOA); the AI / ML models 515-p, 515-q, and 515-r of the sixth group 540 may share another positioning or sensing procedure type (e.g., DL- AOD); the AI / ML models 515-s, 515-t, and 515-u of the seventh group 545 may share input and output attributes; and the AI / ML models 515-v, 515-w, and 515-x of theAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO59 eighth group 550 may share a model structure attribute. While some examples of shared attributes and group structures are described with reference to FIG. 5, other groupings of other share attributes may be implemented in accordance with some examples of the techniques described herein.

[0191] FIG. 6 shows an example of a wireless communications system 600 that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. The wireless communications system 600 may include a first network entity 405-a (e.g., first gNB or TRP), a second network entity 405-b (e.g., second gNB or TRP), a third network entity 405-c (e.g., third gNB or TRP), and a fourth network entity 405-d (e.g., fourth gNB or TRP). The first network entity 405-a, second network entity 405-b, third network entity 405-c, or fourth network entity 405-d may be an example(s) of the network entity 405 described with reference to FIG. 4.

[0192] The first network entity 405-a and the second network entity 405-b may serve a first set 605 of wireless devices 415-a, 415-b, 415-c, and 415-d. The third network entity 405-c and the fourth network entity 405-d may serve a second set 610 of wireless devices 415-e, 415-f, 415-g, 415-h, 415-i, and 415-j. Each of the wireless devices 415-a, 415-b, 415-c, 415-d, 415-e, 415-f, 415-g, 415-h, 415-i, and 415-j may be an example of the wireless device 415 described with reference to FIG. 4. The first set 605 may include an anchor wireless device 415-a, and the second set 610 may include an anchor wireless device 415-e. The anchor wireless device 415-a may be utilized for AI / ML model assignments for the first set 605, and the anchor wireless device 415-e may be utilized for AI / ML model assignments for the second set 610. For instance, the anchor wireless device 415-a may be responsible for assigning an AI / ML model identifier to all of the other wireless devices 415-b, 415-c, and 415-d within the first set 605 as described herein. The anchor wireless device 415-e may be responsible for assigning an AI / ML model identifier to all of the other wireless devices 415-f, 415-g, 415-h, 415-i, and 415-j within the second set 610 as described herein.

[0193] FIG. 7 shows an example of a process flow 700 that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. The process flow 700 may include a wireless device 415-k, which may be an example of a UE 115, UE 115-a, UE 115-b, or wireless deviceAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO60415, as described herein. The process flow 700 may also include a network entity 405-e, which may be an example of a network node 105, network entity, gNB 255, CU 160-a, DU 165-a, RU 170-a, TRP, location server 185, LMF 265, external device 230, SLP 235, SEMF, or network entity 405 as described herein.

While TRPs and UEs are provided in the examples illustrated in FIG. 23, other devices (e.g., network entities, base stations, RRHs, RUs, APs, wireless devices, or stations, among other examples) may be similarly utilized in other examples. The examples of positioning techniques include downlinkbased positioning techniques, uplink-based positioning techniques, and downlink-and- uplink-based positioning techniques.

[0329] Examples of OTDOA or DL-TDOA 2305 are illustrated in FIG. 23. One or more of the OTDOA or DL-TDOA 2305 positioning techniques may be included in a downlink-based positioning procedure. In OTDOA or DL-TDOA 2305 positioning techniques, a UE may measure a difference between TOAs of reference signals (e.g., PRSs) received from one or more pairs of TRPs (e.g., TRP2 and TRP3). In someAttorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref. No. 2406099WO98 approaches, a difference in TOAs may be referred to as an RSTD or a TDOA measurement. A positioning device (e.g., the UE, a location server, an LMF, an SLP, or another device) may utilize the differences in TOAs to determine (e.g., estimate) a location of the UE.

[0330] In some aspects, the UE may receive an identifier (ID) associated with a reference TRP (e.g., a serving base station) and one or more IDs associated with one or more non-reference TRPs in received data (e.g., assistance data). The UE may measure the difference of TOAs between the reference TRP and each of the non-reference TRPs to produce RSTDs or TDOAs. In some aspects, the UE may report an indication of the RSTDs or TDOAs to the positioning device (e.g., a location server, LMF, an SLP, or another device). Based on established locations of the base stations and the RSTD measurements, the positioning device (e.g., the UE for UE-based positioning or a location server for UE-assisted positioning) may estimate the UE’s location.

[0331] An example of UL-TDOA 2310 is illustrated in FIG. 23. One or more of theUL-TDOA 2310 positioning techniques may be included in an uplink-based positioning procedure. UL-TDOA 2310 may have some similarities to DL-TDOA 2305. The UL- TDOA 2310 positioning techniques may be based on uplink reference signals (e.g., SRS) transmitted from the UE to multiple TRPs. For example, the UE transmits one or more uplink reference signals that are measured by a reference TRP (e.g., TRP3) and non-reference TRPs (e.g., TRP1 and TRP2). Each TRP then reports the reception time (which may be referred to as a relative time of arrival (RTOA)) of the reference signal(s) to a positioning device (e.g., a location server, LMF, SLP, or UE) that has information about the locations and relative timing of the TRPs. Based on the reception- to-reception (Rx-Rx) time differences between the reported RTOA of the reference TRP and the reported RTOA of each non-reference TRP, the locations of the TRPs, and the corresponding timing offsets, the positioning device may estimate the location of the UE using TDOA.

[0332] An example of DL-AOD 2315 is illustrated in FIG. 23. One or more of theDL-AOD 2315 positioning techniques may be included in a downlink-based positioning procedure. In DL-AOD 2315, a UE may obtain received signal strength measurements corresponding to multiple downlink transmit beams for one or more TRPs (e.g., TRP1 and TRP2). In some approaches, the UE reports the measurements to a positioningAttorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref. No. 2406099WO99 device. The positioning device may use the signal strength measurements of the multiple downlink transmit beams to determine the angle(s) (e.g., A0D1 and A0D2) between the UE and the transmitting TRP(s). The positioning device (e.g., location server, LMF, SLP, UE, or another device) may estimate the location of the UE based on the determined angle(s) and the established location(s) of the transmitting TRP(s).

[0333] An example of UL-AOA 2320 is illustrated in FIG. 23. One or more of the UL-AOA 2320 positioning techniques may be included in an uplink positioning procedure. In UL-AOA 2320, one or more TRPs (e.g., TRP1 and TRP2) measure the received signal strength of one or more uplink reference signals (e.g., SRSs) received from a UE on one or more uplink receive beams. In some aspects, the signal strength measurements may be reported to a positioning device. A positioning device (e.g., LFM, SLP, UE, or another device) may use the signal strength measurements and the angle(s) of the receive beam(s) to determine the angle(s) between the UE and the TRP(s). Based on the determined angle(s) and the established location(s) of the TRP(s), the positioning device may estimate the location of the UE.

[0334] Some positioning techniques or procedures may include a combination downlink-based and uplink-based positioning techniques. Examples of downlink-based and uplink-based positioning techniques may include E-CID positioning and multi- round-trip-time (RTT) positioning (which may be referred to as “multi-RTT” or “multicell RTT” when multiple cells are utilized).

[0335] In multi-RTT, a first device (e.g., a TRP or UE) may transmit a first RTT- related signal (e.g., a PRS or SRS) to a second device (e.g., the UE or TRP). The second device may transmit a second RTT-related signal (e.g., an SRS or PRS) back to the first device. Each device may measure a time difference between the TOA of the received RTT-related signal and the transmission time of the transmitted RTT-related signal. The time difference may be referred to as a reception-to-transmission (Rx-Tx) time difference. In some aspects, the Rx-Tx time difference measurement may be obtained or adjusted to include (e.g., include only) a time difference between nearest slot boundaries for the received and transmitted signals. The first device or the second device may send the corresponding Rx-Tx time difference measurements to a positioning device (e.g., a location server, LMF, SLP, UE, or other device), which may calculate a round trip propagation time (or RTT) between the two device based on the two Rx-Tx timeAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO100 difference measurements (e.g., as a sum of the two Rx-Tx time difference measurements). Additionally, or alternatively, one device may send a corresponding Rx-Tx time difference measurement to the other device, which may calculate the RTT. The distance between the two devices may be determined from the RTT and a signal speed (e.g., the speed of light).

[0336] An example of multi-cell RTT 2325 is illustrated in FIG. 23. One or more of the multi-RTT or multi-cell RTT techniques described may be included in an uplinkbased or downlink-based positioning procedure. In multi-cell RTT 2325, a first device (e.g., a UE or TRP) may perform an RTT positioning procedure with multiple second devices (e.g., multiple TRPs or UEs) to enable the location of the first device to be determined (e.g., using multilateration) based on distances to, and the established locations of, the second devices.

[0337] In some examples, RTT or multi-RTT techniques may be combined with one or more other positioning techniques (e.g., UL-AOA, DL-AOD, or other positioning techniques), to enhance location accuracy. Examples of combined DL-AOD and RTT 2330 positioning techniques are illustrated in FIG. 23.

[0338] E-CID positioning techniques (not shown in FIG. 23) may be based on radio resource management (RRM) measurements. In E-CID, a UE may obtain or report a serving cell ID, a timing advance (TA), identifiers of one or more detected neighbor TRPs, estimated timing of one or more detected neighbor TRPs, or a signal strength measurement of one or more detected neighbor TRPs. A positioning device (e.g., an LFM, SLP, UE, or another device) may utilize the serving cell ID, TA, identifiers, estimated timing, or signal strength measurements with one or more established locations of one or more TRPs to estimate the location of the UE.

[0339] In some approaches, a positioning device (e.g., location server, LMF, SLP, or another device) may provide assistance data to the UE. Assistance data is data to assist with one or more positioning operations (e.g., to detect one or more neighboring TRPs or to receive reference signaling). For instance, the assistance data may indicate IDs of the TRPs (e.g., IDs of one or more cells or TRPs corresponding to a network node) from which reference signals may be measured. In some examples, a positioning device may transmit assistance data or other information indicating one or moreAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO101 reference signal configuration parameters. The reference signal configuration parameter(s) may include or indicate a quantity of consecutive slots including PRS, a periodicity of consecutive slots including PRS, a muting sequence, a frequency hopping sequence, a reference signal identifier, a reference signal bandwidth, or one or more other parameters applicable to a positioning technique or procedure. Additionally, or alternatively, the assistance data may be sent from one or more TRPs (e.g., in periodically broadcasted overhead messages, a scheduled message, a unicast message, or a multicast message, among other examples). In some examples, a UE may be able to detect one or more neighboring TRPs (e.g., network entities) without the use of assistance data.

[0340] For OTDOA positioning techniques or DL-TDOA positioning techniques, the assistance data may indicate an expected RSTD value and an associated uncertainty or search window around the expected RSTD. For example, an expected RSTD value may have an associated uncertainty or search window with a range of ±500 microseconds (ps). In another example, when any of the resources used for the positioning measurement(s) are in frequency range 1 (FR1), an expected RSTD value may have an associated uncertainty or search window with a range of ±32 ps. In another example, when all of the resources used for the positioning measurement s) are in frequency range 2 (FR2), an expected RSTD value may have an associated uncertainty or search window with a range of ±8 ps.

[0341] In some examples, a location may be referred to as a position estimate, location estimate, position, position fix, or fix, among other examples. A location may be geodetic and include coordinates (e.g., latitude, longitude, or altitude) or may be civic and include a street address, postal address, or another description of a location. In some aspects, a location may be defined relative to another location or may be defined in absolute terms (e.g., latitude, longitude, or altitude). A location may include an indication of error or uncertainty (e.g., by including an area or volume within which the location may be included with a specified or default level of confidence).

[0342] Various examples of sidelink positioning techniques are illustrated in FIG. 23. Sidelink positioning techniques may include positioning techniques that are based on sidelink communication (e.g., based exclusively on sidelink communication orAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO102 based on sidelink communication jointly with other communication(s), such as Uu interface communication).

[0343] A first example of sidelink positioning 2335 is illustrated in FIG. 23. In the first example of sidelink positioning 2335, at least one peer UE with an established location may improve location estimation (e.g., Uu-based positioning, multi-cell RTT, DL-TDOA, or UL-TDOA, among other examples) for a target UE by providing an additional anchor (e.g., sidelink RTT (SL-RTT)).

[0344] A second example of sidelink positioning 2340 is illustrated in FIG. 23. In the second example of sidelink positioning 2340, different types (e.g., categories, classes, or capabilities) of UEs may be utilized. For example, first UEs and a second UE may be utilized. Relative to the second UE, the first UEs may have one or more increased capabilities, such as one or more additional sensors, a faster processor, greater memory capacity, one or more additional antenna elements, a higher transmit power capability, access to one or more additional frequency bands, or any combination thereof. In some aspects, the second UE may be a reduced capacity or “RedCap” UE. The second UE may be assisted by the first UEs to determine the location of the second UE. For instance, sidelink-based positioning or ranging procedures may be performed with the first UEs, which may enhance the location accuracy of the second UE.

[0345] A third example of sidelink positioning 2345 is illustrated in FIG. 23. The third example of sidelink positioning 2345 may be performed via one or more sidelink connections (e.g., via sidelink connections exclusively or jointly with one or more Uu- based connections). In the third example of sidelink positioning 2345, the UEs may perform peer-to-peer (P2P) positioning or ranging. Sidelink positioning may be helpful for out-of-coverage or public safety scenarios. For instance, the UEs may be out of coverage of a network and may determine a location or a relative distance and a relative position among the UEs using sidelink positioning techniques. In some examples, sidelink positioning may be performed by UEs in public safety scenarios (e.g., for police, firefighters, search-and-rescue, or paramedics, among other examples).

[0346] A fourth example of sidelink positioning 2350 is illustrated in FIG. 23. The fourth example of sidelink positioning 2350 may be performed via one or more sidelink connections (e.g., via sidelink connections exclusively or jointly with one or more Uu-Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO103 based connections). In the fourth example of sidelink positioning 2350, one or more of the UEs may determine a location or a relative distance and a relative position using sidelink positioning techniques, such as SL-RTT. For instance, one or more of the UEs may be out of coverage of a network and may determine a location or a relative distance and a relative position among the UEs using sidelink positioning techniques.

[0347] An example of relay positioning 2355 is illustrated in FIG. 23. In the example of relay positioning 2355, a relay UE (e.g., with an established location) may participate in the location estimation of a remote UE (without performing uplink reference signal transmission over the Uu interface, for instance). For example, the relay UE may receive a downlink PRS from a TRP and may relay an SL-PRS to the remote UE. In some cases, the remote UE may also receive another downlink PRS from the TRP. A positioning device (e.g., location server, LMF, SLP, UE, or other device) may utilize a downlink PRS measurement and an SL-PRS measurement with the established location of the relay UE to estimate the location of the remote UE.

[0348] An example of joint positioning 2360 is illustrated in FIG. 23. In the example of joint positioning 2360, multiple peer UEs (without established locations, for instance) may be located. In some approaches, multiple peer UEs may be jointly located in NLOS conditions by utilizing one or more constraints from one or more peer (e.g., neighboring or nearby) UEs. As illustrated in FIG. 23, RTT or TDOA techniques may be performed between TRP1 and each of the peer UEs, may be performed between TRP2 and each of the peer UEs, and may be performed between the peer UEs. In some examples, one or more of the peer UEs may report measurements from the RTT or TDOA technique(s) to a positioning device. The positioning device (e.g., location server, LMF, SLP, UE, or other device) may utilize the measurements from the RTT or TDOA technique(s) to estimate the locations of the peer UEs.

[0349] Some aspects of the techniques described herein may be performed in conjunction with one or more of the positioning techniques described with reference to FIG. 23. For instance, one or more samples of a reference signal (e.g., PRS, SRS, or other reference signal) may be measured or transmitted in accordance with one or more of the techniques described with reference to FIG. 4 for one or more of the positioning techniques. Some examples of the positioning techniques may be performed in one orAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO104 more wireless communications systems 2300, such as LTE and NR, where NR may support sidelink communications.

[0350] FIG. 24 shows an example of a node diagram 2400 that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. Al models are programmatic or algorithmic structures that simulate intelligent behavior. Machine learning models may be examples of Al models. Machine learning models are programmatic or algorithmic structures that may be trained to infer or predict an output based on an input. For example, a machine learning model may be trained using training input data and ground truth data.

[0351] Machine learning models may be categorized as unsupervised or supervised. Unsupervised learning may be utilized to draw inferences and find patterns from input data without references to labeled outcomes. Two examples of unsupervised learning models include clustering and dimensionality reduction. Clustering is an unsupervised technique that involves the grouping, or clustering, of data points. Clustering techniques may include k-means clustering, hierarchical clustering, mean shift clustering, and density-based clustering. Dimensionality reduction may be a procedure for reducing a quantity of random variables under consideration by obtaining a set of principal variables. Dimensionality reduction may reduce the dimension of a feature set or reduce a quantity of features). Some dimensionality reduction techniques may be categorized as feature elimination or feature extraction. One example of dimensionality reduction may be referred to as principal component analysis (PCA). PCA may involve projecting higher dimensional data (e.g., three dimensions) to a lower-dimensional space (e.g., two dimensions), which may result in a lower dimension of data (e.g., two dimensions instead of three dimensions) while maintaining one or more variables in the model.

[0352] Supervised learning involves learning a function that maps an input to an output based on associated inputs and outputs. For instance, supervised learning may be utilized to draw inferences and find patterns from input data based on labeled data (e.g., training input data with associated ground truth data). A supervised model may subcategorized as a regression or classification model. Regression models may provide continuous outputs. One example of a regression model is a linear regression, which may determine a line that fits (e.g., best fits) input data. Extensions of linear regressionAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO105 include multiple linear regression (e.g., finding a plane of best fit) and polynomial regression (e.g., finding a curve of best fit).

[0353] In classification models, the output may be discrete. One example of a classification model is logistic regression. Logistic regression may be similar to linear regression, but may be used to model a probability for a finite quantity of outcomes. For example, a logistic regression may be utilized such that the output values may be between 0 and 1. Another example of a classification model is a support vector machine. For two classes of data, for example, a support vector machine may determine a hyperplane or a boundary between the two classes of data that maximizes a margin between the two classes. For instance, many planes may separate two classes, while one plane may maximize the margin or distance between the classes. Another example of a classification model is Naive Bayes, which is based on Bayes Theorem.

[0354] Other examples of classification models include decision tree models, random forest models, and neural network models, where an output may be discrete. In a decision tree model, a tree structure is defined with multiple nodes. Decisions may be used to move from a root node at the top of the decision tree to a leaf node (e.g., a node without a child node) at the bottom of the decision tree. A higher quantity of nodes in the decision tree model may correlate with higher decision accuracy.

[0355] Random forest models may utilize ensemble learning techniques that build from decision tree models. Random forests involve creating multiple decision trees using bootstrapped datasets of the original data and randomly selecting a subset of variables at each tier of the decision tree. The model may select the mode of all of the predictions of each decision tree. By relying on a “majority wins” model, the risk of error from an individual tree may be reduced.

[0356] Another example of a machine learning model is a neural network (NN). A neural network may be a network of functional nodes. Neural networks may utilize one or more input variables to traverse the nodes and generate one or more output variables. For example, a neural network may utilize an input vector to generate an output vector.

[0357] The Al model illustrated in FIG. 24 is an example of a neural network. The neural network includes an input layer i that receives n (one or more) inputs (illustrated as “Input 1,” “Input 2,” and “Input n”), one or more hidden layers (illustrated as hiddenAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO106 layers “hl,” “h2,” and “h3”) for processing the inputs from the input layer, and an output layer o that provides m (one or more) outputs (labeled “Output 1” and “Output m”). While examples of quantities of inputs n, hidden layers h, and outputs m are illustrated in FIG. 24, same or different quantities of inputs, hidden layers, or outputs may be utilized in other examples. In some approaches, the hidden layers h may include linear function(s) or activation function(s) that the nodes (illustrated as circles) of each successive hidden layer process from the nodes of the previous hidden layer.

[0358] In some aspects, the Al model illustrated in FIG. 24 or another Al model may be trained in accordance with one or more training techniques. In some examples of the training techniques described herein, one or more Al models (e.g., implemented by one or more devices) may be trained based on training input data (e.g., measurements of reference signals to or from various UEs) and ground truth data (e.g., locations of the various UEs), thereby enabling later determination of an output (e.g., an inferred or prediction location or measurement) when an Al model is executed with runtime input data (e.g., from other UEs).

[0359] Ground truth data may be data representing a target output associated with training input data. Ground truth data may be generated or observed (e.g., empirical) data. In some examples, ground truth data may indicate one or more observed locations (e.g., coordinates or addresses, among other examples) corresponding to training input data. Examples of training input data may include reference signal data (e.g., measurements of a PRS, SRS, reference signal of an SSB, CSI-RS, DMRS, or TRS, among other examples), signal data (e.g., signal strength data, RSRP data, RSRPP data, RS SI data, RSRQ data, SINR data, or SNR data, among other examples), channel data (e.g., CIR data, PDP data, DP data, CQI data, CSI data, decoding failure rate, or retransmission request rate, among other examples), AOA data, AOD data, TDOA data, RTT data, TA data, sensor data (e.g., image data, RF data, motion data, orientation data, or audio data, among other examples), or identifier data (e.g., cell ID data or service set identifier (SSID) data, among other examples), among other examples.

[0360] In some examples, ground truth data may indicate one or more measurements or values (e.g., AOA measurements, AOD measurements, TDOA measurements, RTT measurements, line-of-sight (LOS) angle(s), or other values) corresponding to training input data. Examples of training input data may includeAttorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref. No. 2406099WO107 reference signal data (e.g., measurements of a PRS, SRS, reference signal of an SSB, CSI-RS, DMRS, or TRS, among other examples), signal data (e.g., signal strength data, RSRP data, RS SI data, RSRQ data, SINR data, or SNR data, among other examples), channel data (e.g., CIR data, PDP data, DP data, CQI data, CSI data, decoding failure rate, or retransmission request rate, among other examples), TA data, sensor data (e.g., image data, RF data, motion data, orientation data, or audio data, among other examples), or identifier data (e.g., cell ID data or SSID data, among other examples), among other examples.

[0361] An Al model (e.g., the Al model illustrated in FIG. 24 or a machine learning model) may be trained by executing the Al model with the training data to produce an output, comparing the output with the ground truth data, and adjusting weights of the Al model to reduce a disparity between the output and the ground truth data. For example, one or more of the nodes or connections of the Al model may have an associated weight that may be adjusted to modify one or more of the outputs. In some approaches, a cost function may be utilized to compare the output with the ground truth data to indicate a cost (e.g., error or disparity). Adjustments to the weights that reduce the cost may be retained, advanced, or increased, while adjustments to the weights that increase the cost may be discarded, avoided, or decreased. Training procedures may be repeated or iterated to improve Al model performance.

[0362] Input data (e.g., runtime input data) may be provided to a trained Al model, which may infer or predict an output based on the input data. Some examples of Al models may be trained to infer or predict a location based on input data (e.g., reference signal data, signal data, channel data, AOA data, AOD data, TDOA data, RTT data, TA data, sensor data, or identifier data, among other examples). Some examples of Al models may be trained to infer or predict measurements or values (e.g., timing measurement(s), angle measurement s), AOA measurement(s), AOD measurement(s), TDOA measurement s), RTT measurements), LOS angle(s), or other values) based on input data.

[0363] Some examples of the techniques described herein may be performed in conjunction with one or more of the Al models described with reference to FIG. 24. For instance, an Al model may be split or executed in portions as described with reference to FIG. 4.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO108

[0364] FIG. 25A shows an example of a block diagram 2500-a that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. In some examples of the techniques described herein, a positioning device (e.g., location server, LMF, SnMF, SLP, UE, or other device) may utilize D-AI / ML positioning or sensing. In D-AI / ML positioning, one or more Al models 2510 (e.g., machine learning model(s) or D-AI / ML model(s)) may be trained to utilize input data 2505 to output (e.g., infer or predict) object data 2515 (e.g., location, velocity, range, position estimate, coordinates, or an address of an object). Examples of the input data 2505 may include reference signal data (e.g., measurements of a PRS, SRS, reference signal of an SSB, CSLRS, DMRS, or TRS, among other examples), signal data (e.g., signal strength data, RSRP data, RSRPP data, RSSI data, RSRQ data, SINR data, or SNR data, among other examples), channel data (e.g., CFR data, CIR data, PDP data, DP data, CQI data, CSI data, decoding failure rate, or retransmission request rate, among other examples), AOA data, AOD data, TDOA data, RTT data, TA data, RSTD data, difference of RSTDs (diff-RSTD) data, RTOA data, difference of RTOAs (diff-RTOA) data, sensor data (e.g., range map data, Doppler map data, space map data, image data, RF data, motion data, orientation data, or audio data, among other examples), or identifier data (e.g., cell ID data or SSID data, among other examples), among other examples.

[0365] FIG. 25B shows a block diagram 2500-b that supports information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. In some examples of the techniques described herein, a positioning device (e.g., location server, LMF, SLP, UE, or other device) may utilize A-AI / ML (or indirect) positioning. In A-AI / ML, one or more Al models 2530 (e.g., machine learning model(s) or “A-AI / ML” model(s)) may be trained to utilize input data 2525 to output (e.g., infer or predict) one or more inferred measurements 2535. For instance, an AI / ML model may output a new measurement or an enhancement of a measurement (e.g., LOS / NLOS identification, timing of measurement, angle of measurement, likelihood of measurement, an enhanced Doppler map, an enhanced range map, or an enhanced angle map, among other examples). The Al model(s) 2530 may be located at a wireless device or network entity (e.g., UE or network node). Examples of the input data 2525 may include reference signal data (e.g., measurements of a PRS, SRS, reference signal of anAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO109SSB, CSI-RS, DMRS, or TRS, among other examples), signal data (e.g., signal strength data, RSRP data, RSRPP data, RS SI data, RSRQ data, SINR data, or SNR data, among other examples), channel data (e.g., CFR data, CIR data, PDP data, DP data, CQI data, CSI data, decoding failure rate, or retransmission request rate, among other examples), AOA data, AOD data, TDOA data, RTT data, TA data, RSTD data, diff-RSTD data, RTOA data, diff-RTOA data, sensor data (e.g., range map data, Doppler map data, space map data, image data, RF data, motion data, orientation data, or audio data, among other examples), or identifier data (e.g., cell ID data or SSID data, among other examples), among other examples. Examples of the inferred measurements 2535 may include one or more intermediate positioning measurements, timing measurements, Rx- Tx time difference measurements (e.g., from the perspective of a wireless device or network node), RSTD measurements, RTOA measurements, angle measurements, AOA measurements, AOD measurements, TDOA measurements, RTT measurements, a LOS indicator, LOS angles, an enhanced Doppler map, an enhanced range map, or an enhanced angle map, among other examples.

[0366] In A-AI / ML, the input data 2525 or Al model(s) 2530 may be structured in accordance with one or more approaches. Different model input structures may have different implications regarding model output accuracy, generalization, robustness, or model complexity.

[0367] In some approaches, a same Al model 2530 may be utilized (e.g., separately utilized) for input data 2525 from multiple (e.g., P) TRPs, where a separate input may be utilized for input data 2525 from each respective TRP. For instance, a first CIR corresponding to a first TRP may be utilized as an input for the Al model 2530 to generate a first TOA corresponding to the first TRP, a second CIR corresponding to a second TRP may be utilized as an input for the Al model 2530 to generate a second TOA corresponding to the second TRP, and an Kth CIR corresponding to an Kth TRP may be utilized as an input for the Al model 2530 to generate an Kth TOA corresponding to the Kth TRP. The first TOA, the second TOA, and the Kth TOA may be examples of the inferred measurements 2535.

[0368] In some approaches, different Al models 2530 (e.g., K Al models) may be utilized for input data 2525 from multiple (e.g., K) TRPs, where a separate input may be utilized for input data 2525 from each respective TRP. For instance, a first CIRAttorney Docket No. PB0009GR.WO (114958.5251)Qualcomm Ref. No. 2406099WO110 corresponding to a first TRP may be utilized as an input for a first Al model to generate a first TOA corresponding to the first TRP, a second CIR corresponding to a second TRP may be utilized as an input for a second Al model to generate a second TOA corresponding to the second TRP, and an Kth CIR corresponding to an Kth TRP may be utilized as an input for an Kth Al model to generate an Kth TOA corresponding to the Kth TRP. The first Al model, the second Al model, and the Kth Al model may be examples of the Al models 2530. The first TOA, the second TOA, and the Kth TOA may be examples of the inferred measurements 2535.

[0369] In some approaches, one Al model 2530 may be utilized (e.g., jointly or concurrently utilized) for input data 2525 from multiple (e.g., P) TRPs, where a separate input may be utilized for input data 2525 from each respective TRP. For instance, a first CIR corresponding to a first TRP, a second CIR corresponding to a second TRP, and an Kth CIR corresponding to an Kth TRP may be utilized as inputs for the Al model 2530 to generate a first TOA corresponding to the first TRP, a second TOA corresponding to the second TRP, and an Kth TOA corresponding to the Kth TRP. The first TOA, the second TOA, and the Kth TOA may be examples of the inferred measurements 2535.

[0370] The inferred measurement(s) 2535 may be provided to, or utilized by, a positioning device (e.g., location server, LMF, SnMF, SLP, UE, or other device) to output object data 2545 (e.g., location, velocity, range, a position estimate, coordinates, or an address of an object). For example, the positioning device may include a positioning component 2540. The positioning component may be, or may utilize, one or more other Al models (e.g., positioning model(s)) or non-AI models (constant false alarm rate (CFAR) detector, matched filter, trilateration with Chan’s algorithm, a Kalman filter, or an AI / ML sensing model, among other examples) to determine the object data 2545 (e.g., UE coordinates). In some examples, the Al model(s) 2530 and the positioning component 2540 may be implemented at the same device (e.g., location server, LMF, SLP, UE, or other device) or at different devices. For network-assisted positioning, for instance, a UE may apply the Al model(s) 2530 to generate the inferred measurement(s) 2535, which may be reported to an network entity (e.g., location server, LMF, or SnMF, among other examples). The network entity may apply the positioning component 2540 to generate the object data 2545. For UE-based positioning, a device (e.g., a network node, location server, LMF, or another UE with a sidelink connection toAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WOI l l the UE) may apply the Al model(s) 2530 to generate the inferred measurement(s) 2535, which may be reported to the UE, which may apply the positioning component 2540 to generate the object data 2545.

[0371] Some examples of the techniques described herein may be performed in conjunction with one or more of the D-AI / ML positioning or sensing described with reference to FIG. 25A or the A-AI / ML positioning or sensing described with reference to FIG. 25B. For instance, one or more samples of a reference signal (e.g., PRS, SRS, or other reference signal) may be examples of input data 2505 or input data 2525, or the Al model(s) 2510 or the Al model(s) 2530 may produce inferred measurements 2535 based on the samples.

[0372] In some examples of non-AI / ML-based positioning, a path finding procedure (e.g., LOSQuad, multiple signal classification (MUSIC), or matching pursuit (MP), among other examples), may utilize input data (e.g., reference signal data (e.g., PRS or SRS measurements) or channel data (e.g., CFR data, CIR data, PDP data, or DP data) to produce intermediate positioning measurements. Examples of the intermediate positioning measurements may include Rx-Tx time difference measurements (e.g., from the perspective of a wireless device or network node), RSTD measurements, RTOA measurements, a LOS indicator, or other values. The intermediate positioning measurements may be provided to a positioning engine, which may perform one or more procedures (e.g., trilateration with Chan’s algorithm or a Kalman filter, among other examples) to determine a location (e.g., UE coordinates). Some non-AI / ML-based positioning procedures (e.g., RAT-dependent positioning procedures) may fail in NLOS conditions. One or more AI / ML-based positioning procedures may enhance positioning accuracy in NLOS conditions because the AI / ML model(s) may learn a channel multipath profile and the profile’s mapping to location information.

[0373] FIG. 26 shows examples of block diagrams 2600 that support information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. A first use case 2605 (e.g., “Case 1”) may be an example of UE-based positioning or sensing, where the UE includes an Al model. In the first use case 2605, the Al model may be utilized for D-AI / ML positioning or sensing or A-AI / ML positioning or sensing (e.g., UE-based positioning or sensing with UE-side A- AI / ML or D-AI / ML). For example, a network node or UE may transmit a referenceAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO112 signal (e.g., PRS) to the UE. In a D-AI / ML positioning approach, the UE may execute the Al model based on measurements of the reference signal to determine a location. An indication of the location (e.g., UE coordinates) may be transmitted to the location server (e.g., LMF). In an A-AI / ML approach, the UE may execute the Al model based on measurements of the reference signal to determine one or more inferred measurements (e.g., based on the PRS). The UE may utilize the inferred measurement(s) to determine the location using another Al model or a non- Al model. An indication of the location may be transmitted to the location server.

[0374] A second use case 2610 (e.g., “Case 2a”) may be an example of UE-assisted or location server-based positioning, where the UE includes an Al model. In the second use case 2610, the Al model may be utilized for AI / ML assisted positioning or sensing (e.g., UE-assisted positioning or sensing with UE-side A-AI / ML). For example, a network node or UE may transmit a reference signal (e.g., PRS) to the UE. In the A- AI / ML approach, the UE may execute the Al model based on measurements of the reference signal to determine one or more inferred measurements (e.g., based on the PRS). For instance, the inferred measurement(s) may include PRS-based measurement(s) (e.g., an RSTD, LOS indicator, or UE Rx-Tx time difference, among other examples) as model output(s). An indication of the inferred measurement(s) may be transmitted to the location server (e.g., LMF or SnMF). The location server may utilize the inferred measurement(s) to determine the location using an Al model or non- AI model.

[0375] A third use case 2615 (e.g., “Case 2b”) may be an example of UE-assisted or location server-based positioning, where the location server (e.g., LMF or SnMF) includes an Al model (e.g., UE-assisted positioning or sensing with location server or SnMF-side D-AI / ML). In the third use case 2615, the Al model may be utilized for D- AI / ML positioning. For example, a network node or UE may transmit a reference signal (e.g., PRS) to the UE. The UE may measure the reference signal and transmit an indication of the measurement s) to the location server. In a D-AI / ML positioning approach, the location server may execute the Al model based on the measurement(s) of the reference signal to determine a location. For instance, the measurement(s) may include one or more PRS-based measurements as model input (e.g., CIR, PDP, DP, RSTD, diff-RSTD, RSRP, or RSRPP, among other examples).Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO113

[0376] A fourth use case 2620 (e.g., “Case 3a”) may be an example of network node-assisted positioning, where the network node includes an Al model. In the fourth use case 2620, the Al model may be utilized for A-AI / ML (e.g., network node or UE- assisted positioning or sensing with network node, UE, or SnMF-side A-AI / ML). For example, a UE may transmit a reference signal (e.g., SRS) to the network node. The network node may measure the reference signal. In the A-AI / ML approach, the network node may execute the Al model based on a measurement(s) of the reference signal to determine one or more inferred measurements (e.g., based on the SRS). For instance, the inferred measurement s) may include an SRS-based measurement as model output (e.g., an RTOA, LOS indicator, network node Rx-Tx time difference, among other examples). An indication of the inferred measurement(s) may be transmitted to the location server (e.g., LMF). The location server may utilize the inferred measurement s) to determine the location using an Al model or a non- Al model.

[0377] A fifth use case 2625 (e.g., “Case 3b”) may be an example of network nodeassisted positioning, where the location server (e.g., LMF or SnMF) includes an Al model. In the fifth use case 2625, the Al model may be utilized for D-AI / ML positioning (e.g., network node-assisted positioning or sensing with location server or SnMF-side D-AI / ML). For example, a UE may transmit a reference signal (e.g., SRS) to the network node. The network node may measure the reference signal (e.g., based on the SRS) and transmit an indication of the measurement s) to the location server. For instance, the measurement s) may include an SRS-based measurement as model input (e g., CIR, PDP, DP, RTOA, diff-RTOA, RSRP, or RSRPP, among other examples). In a D-AI / ML positioning approach, the location server may execute the Al model based on the measurements) of the reference signal to determine a location. Other examples may be implemented in which a UE, network node (e.g., gNB), location server (e.g., LMF or SnMF) utilizes AI / ML to report or computing sensing.

[0378] Some examples of the techniques described herein may provide positioning or sensing accuracy enhancements for D-AI / ML positioning or sensing, or for A-AI / ML positioning or sensing. D-AI / ML use cases may include Case 1 (e.g., UE-based positioning with a UE-side Al model and D-AI / ML positioning), Case 2b (e.g., UE- assisted or location server-based positioning with an location server-side Al model and D-AI / ML positioning), Case 3b: NG-RAN node assisted positioning with an locationAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO114 server-side Al model and D-AI / ML positioning). A-AI / ML use cases may include Case 2a (e.g., UE-assisted or location server-based positioning with a UE-side Al model and A-AI / ML positioning) or Case 3a (e.g., NG-RAN node assisted positioning with a gNB- side Al model and A-AI / ML positioning.

[0379] For direct AI / ML positioning (e.g., Case 2b or Case 3b), one or more types of measurements may be utilized as model inference input, which may impact performance or associated signaling overhead. Some examples of measurements may include CIR, PDP, RSRP, RSRPP, or RSTD, among others. For A-AI / ML assisted positioning with UE-assisted (Case 2a) and NG-RAN node assisted positioning (Case 3a), one or more measurements may be signaled in a measurement report. For instance, a measurement report may be utilized to carry model output to an LMF. A measurement report may include data indicating a TOA, path phase, RSTD, LOS indicator or NLOS indicator, or RSRPP. Some measurement reports may include soft information or relatively high resolution information of an RSTD. One or more types of model inference output may be utilized to provide performance benefits. Examples of model inference outputs may include a timing estimate (e.g., a report to an LMF may be derived based on, or may be different from, the model inference output), an LOS or NLOS indicator. In some approaches, assistance signaling (e.g., reference signal configurations) may be utilized with a procedure to facilitate model inference for a UE- side model or a network-side model.

[0380] Some examples of the techniques described herein may be performed in conjunction with one or more of the use cases (e.g., the first use case 2605, the second use case 2610, the third use case 2615, the fourth use case 2620, or the fifth use case 2625) described with reference to FIG. 26. It should be noted that while examples of some use cases are illustrated in FIG. 26, other use cases in which a device (e.g., wireless device, network entity, UE, network node, location server, or LMF, among other examples) may receive a reference signal, measure a reference signal, report measurements, infer measurements, infer a location, or report a location may be implemented.

[0381] For AI / ML assisted positioning with UE-assisted positioning (Case 2a) or NG-RAN node-assisted positioning (Case 3a), a measurement report may include or indicate a model output to the location server. A measurement report may includeAttorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO115 information indicating TOA, path phase, RSTD, a LOS or NLOS indicator, or RSRPP. In some approaches, a measurement report may include probabilistic (e.g., soft) information or an increased resolution of RSTD. One or more Al model inference outputs may improve performance, such as timing estimation (where a report to the location server may be derived based on the Al model inference output or may be different from the model inference output, for instance), or a LOS or NLOS indicator. Assistance signaling (e.g., reference signal configuration information) may be utilized to facilitate model inferencing for a UE-side or network-side model(s).

[0382] For AI / ML assisted positioning (e.g., Case 3a), an LOS indicator, NLOS indicator, or timing information may be supported for reporting. If an LOS indicator or NLOS indicator is reported, the indicator can be reported as a soft indicator or a hard indicator. If timing information is reported, the timing information may be reported via UL RTOA or gNB Rx-Tx time difference. For AI / ML assisted positioning (e.g., Case 2a), an LOS indicator, NLOS indicator, or timing information may be supported for reporting. If the LOS indicator or NLOS indicator is reported, the indicator may be reported as a soft indicator or a hard indicator. If timing information is reported, the timing information may be reported via downlink RSTD or UE Rx-Tx time difference.

[0383] FIG. 27 shows examples of sensing modes 2700 that support information signaling for AI / ML-based positioning or sensing in accordance with one or more aspects of the present disclosure. Various sensing modes are illustrated in the context of one or more devices (e.g., TRPs and UEs). While TRPs are illustrated in FIG. 27, a TRP may instead be a base station (e.g., gNB) in some examples. The objects illustrated in FIG. 27 may be devices (e.g., UEs, AGVs, or vehicles, among other examples) or passive objects (e.g., roads, signs, barriers, or rocks, among other examples).

[0384] One or more sensing operations may be performed in accordance with one or more of the techniques described herein. Sensing operations may include monostatic sensing (e.g., radar-like sensing, where a sensing transmitter and a sensing receiver may be co-located in the same entity) or bistatic sensing (e.g., where a sensing receiver and sensing transmitter are located in different entities). Multi-static sensing may be performed in some examples, where multiple sensing transmitters or receivers may be utilized.Attorney Docket No. PB0009GR.WQ (114958.5251)Qualcomm Ref. No. 2406099WO116

[0385] In some approaches, one or more reflections of a sensing signal sent from a sensing transmitter may be received by a sensing receiver and processed to determine one or more characteristics of the sensed object or an environment (e.g., location). In sensing operations, one or more sensing signal reflections may be received. The sensing signal reflections may be processed locally (e.g., in a device that received the sensing signal reflections) or may be communicated to another device for processing. For instance, a device may execute one or more AI / ML models to determine a position of the object based on the sensing signal reflections.
