[0001] The present Application for Patent claims priority to Greece Patent Application No. 20240100791 by HIRZALLAH et al., entitled “IDENTIFIERS FOR ARTIFICIAL INTELLIGENCE OR MACHINE LEARNING-BASED POSITIONING,” filed November 8, 2024, which is assigned to the assignee hereof, and expressly incorporated by reference in its entirety herein.FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications, including grouping types for network settings and associated identifiers for artificial intelligence or machine learning-based positioning.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. PB0021GR.WO (114958.5216)Qualcomm Ref.

[0067] Some wireless communication systems utilize measurements to generate a positioning estimate of a user equipment (UE). Artificial intelligence or machine learning (AI / ML) positioning may improve positioning accuracy in stringent non-line- of-sight (NLOS) conditions. In some approaches, a network node (e.g., a gNB or one or more transmission-reception points (TRPs)) may change network settings. Examples of network settings may include a TRP relative time difference, a TRP reference signal (e.g., positioning reference signal (PRS)), transmission power, a TRP reference signal beam shape, or proprietary network information, among other examples. A network node may change network settings without explicitly indicating one or more actual values or a range of values for the network settings, in some examples. Because changing network settings may impact reference signaling or other network behavior, aAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO13 change in network settings may cause a misalignment or lack of correspondence between the network settings and a UE-side AI / ML model, which may impact (e.g., reduce) positioning accuracy. For instance, an indication of network settings may not be provided to a UE.
[0068] In some examples of the techniques described herein, one or more network settings may be associated with (e.g., mapped to) an identifier. In some approaches, a network entity (e.g., location management function (LMF) may indicate one or more identifiers to a wireless device (e.g., UE) for checking an AI / ML model on the wireless device (e.g., UE). A challenge may arise where a network may have a plurality of network settings (e.g., TRP or ARP location and orientation information, beam shape and angle information, TRP relative time differences, TRP transmit or receive (Tx / Rx) timing errors, or Tx power, among other examples). For example, some network settings may have a correspondence with an associated identifier. Some examples of the techniques may provide that a UE and an LMF may exchange signaling related to grouping of network settings or a correspondence of network settings to an associated identifier.
[0069] 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 a diagram and 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 grouping types for network settings and associated identifiers for AI / ML-based positioning.
[0070] FIG. 1 shows an example of a wireless communications system 100 that supports grouping types for network settings and associated identifiers for AI / ML-based positioning 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 withAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO14 other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0071] 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).
[0072] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or 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.
[0073] 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 nodeAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO15 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.
[0074] 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 a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication link(s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link), among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0075] 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 oneAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO16 network node (e.g., a network node 105 or a single RAN node, such as a base station 140).
[0076] 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 TRP. One or more components of 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)).
[0077] 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 anAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO17RU 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 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network nodes 105) that are in communication via such communication links.
[0078] 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., IABAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO18 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.
[0079] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor), IAB node(s) 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, an IAB donor may refer to a RAN node with a wired or wireless connection to the core network 130. The IAB donor may include one or more of a CU 160, a DU 165, and an RU 170, in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and IAB node(s) 104 may communicate via an Fl interface according to a protocol that defines signaling messages (e.g., an Fl AP protocol). Additionally, or alternatively, the CU 160 may communicate with the core network 130 via an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs (e.g., including a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of another portion of a backhaul link.
[0080] 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 relayAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO19 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.
[0081] 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 115 relayed from the IAB donor) through one or more DUs (e.g., DUs 165). That is, data may be relayed to and from IAB node(s) 104 via signaling via an NR Uu interface to MT of IAB node(s) 104 (e.g., other IAB node(s)). Communications with IAB node(s) 104 may be scheduled by a DU 165 of the IAB donor or of IAB node(s) 104.
[0082] 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).
[0083] 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 digitalAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO20 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.
[0084] 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.
[0085] 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) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network 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).Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO21
[0086] 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).
[0087] 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).
[0088] 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.
[0089] 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 mayAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO22 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.
[0090] 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 a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
[0091] 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 / mflx■ Ay) seconds, for which fmaxmay represent a supported subcarrier spacing, and Ay may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).
[0092] 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,Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO23 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.
[0093] 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)).
[0094] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE).
[0095] 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 anyAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO24 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.
[0096] 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. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG), the UEs 115 associated with users in a home or office). A network 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.
[0097] 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.
[0098] 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 coverageAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO25 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.
[0099] 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.
[0100] Some UEs 115, such as MTC or loT devices, may be relatively low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network 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.
[0101] 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 beAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO26 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.
[0102] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC). The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0103] 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 communicationsAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO27 may be carried out between the UEs 115 without an involvement of a network node 105.
[0104] 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.
[0105] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network 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.
[0106] 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, relativeAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO28 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.
[0107] 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.
[0108] 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 backhaulAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO29 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.
[0109] 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.
[0110] 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.[OHl] 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.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO30
[0112] 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.
[0113] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0114] 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., baseAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO31 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.
[0115] 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.
[0116] 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.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO32
[0117] 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.
[0118] 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 spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).
[0119] 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) toAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO33 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.
[0120] 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 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0121] 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 baseAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO34 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).
[0122] 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 receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to- noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).
[0123] 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 130Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO35 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0124] 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.
[0125] Some wireless communication systems utilize measurements to generate a positioning estimate of a UE 115. AI / ML positioning may improve positioning accuracy in stringent NLOS conditions. In some approaches, a network node 105 (e.g., a gNB or one or more TRPs) may change network settings. Examples of network settings may include a TRP relative time difference, a TRP reference signal (e.g., PRS), transmission power, a TRP reference signal beam shape, or proprietary network information, among other examples. A network node 105 may change network settings without explicitly indicating one or more actual values or a range of values for the network settings, in some examples. Because changing network settings may impact reference signaling or other network behavior, a change in network settings may cause a misalignment or lack of correspondence between the network settings and a UE-side AI / ML model (for Case 1 or Case 2a as described with reference to FIG. 24, for example), which may impact (e.g., reduce) positioning accuracy. For instance, an indication of network settings may not be provided to a UE 115.
[0126] In some examples of the techniques described herein, one or more network settings may be associated with (e.g., mapped to) an identifier. In some approaches, a network entity (e.g., a location server 185 or LMF, among other examples) may indicate one or more identifiers to a wireless device (e.g., UE 115) for checking an AI / MLAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO36 model on the wireless device (e.g., UE 115). A challenge may arise where a network may have a plurality of network settings (e.g., TRP or ARP location and orientation information, beam shape and angle information, TRP relative time differences, TRP Tx / Rx timing errors, or Tx power, among other examples). For example, some network settings may have a correspondence with an associated identifier. Some examples of the techniques may provide that a UE 115 and a location server 185 (e.g., an LMF) may exchange signaling related to grouping of network settings or a correspondence of network settings to an associated identifier.
[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 (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that supports grouping types for network settings and associated identifiers for AI / ML-based positioning 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) in hardware (e.g., circuitry) or a combination of hardware and instructions (e.g., aAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO37 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., interception), traffic usage reporting, quality of service (QoS) handling for the U-planeAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO38(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).

In some examples, the LMF 265 may communicate with a UE 115-a or another device via a C-plane connection (e.g., using one or more interfaces or protocols for signaling control information, or separate from voice or payload data). In some aspects, the LMF 265 may be integrated into a component of the core network 130-a or may be external to the core network 130-a (e.g., on an external device 230, such as an original equipment manufacturer (OEM) server or other server).

[0139] FIG. 3 shows an example of a network architecture 300 (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that supports grouping types for network settings and associated identifiers for AI / ML-basedAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO41 positioning 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. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO42 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. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO43 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. PB0021GR.WO (114958.5216)Qualcomm Ref.

The wireless communications system 400 also includes a network entity 405. The network entity 405 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, an 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 an RU 170-b, DU 165-b, or CU 160-b described with reference to FIG. 3.
[0148] The wireless device 415 may communicate with the network entity 405 using a link 425. The link 425 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, or sidelink network communications. For example, the wireless device 415 may transmit one or more uplink transmissions (not shown in FIG. 4), such as uplink control signals or uplink data signals, to the network entity 405 using the link 425, or the network entity 405 may transmit one or more downlink transmissions 410, such as downlink control signals or downlink data signals, to the wireless device 415 using the link 425.
[0149] A network setting may be a parameter or a condition of operation for a network entity 405 or network node. In some examples, network settings may be (or may correspond to) information related to one or more network nodes (e.g., gNB(s) or TRP(s)), one or more conditions (e.g., additional conditions) related to reference signal transmission at the network side (e.g., gNB or TRP side), network transmission (e.g.,Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref.

In some aspects, the network entity 405 (e.g., included in a core network) and a network node (e.g., included in a radio access network) may be included in a network. For instance, a network node (not shown in FIG. 4) may apply one or more network settings for communicating with the wireless device 415. The network node may be associated with the network entity 405. For instance, the network node may be a base station (e.g., gNB) that relays communications (e.g., signal(s) or information) between the wireless device 415 and the network entity 405.
[0150] Some examples of the one or more network settings may include (e.g., may not be limited to), information indicating a location of a TRP (or PRU) or an antenna reference point (ARP), an uncertainty of a location of a TRP or an ARP, an integrity of a location of a TRP or an ARP, a beam shape (of a TRP or PRS, for instance), a beam angle (e.g., pointing angle) (of a TRP or PRS, for instance), an average or confidence of a beam angle (e.g., pointing angle) (of a TRP or PRS, for instance), a range of a beam angle, an integrity of beam information, TRP beam antenna information, a transmit power (e.g., a PRS transmit power), a power integrity, a relative time difference between TRPs, an integrity of a relative time difference between TRPs, a transmit timing error (for a network node, TRP, or group of TRPs, for instance), an integrity of timing error, integrity information, an identifier of a group of network nodes (for network nodes or TRPs, for instance), an LOS or NLOS state (e.g., TRP expected LOS), PRU information, PRU calibration information, or calibration assistance information associated with a PRU, among other examples. In some examples, the wireless device 415, a network node, or the network entity 405 may communicate (e.g., output, transmit, obtain, or receive between each other) information indicating the one or more network settings.
[0151] Some examples of network settings of an information indicating a location of a TRP or ARP, or an integrity of a location of a TRP or ARP may include one or more of the following. An nr- TRP -Locationinfo field may provide location coordinates of one or more TRPs or location coordinates of antenna reference points for downlink PRS (DL-PRS) Resource Set(s) or DL-PRS Resources of the TRPs.

A dl-PRS-ResourceARP-ErrorCorrelationTime field may specify a DL-PRS Resource ARP Error Correlation Time, which may be an upper bound of a correlation time of a DL-PRS Resource ARP error. A dl-PRS-Re source Set ARP or dl-PRS-ResourceSetARP-Cartesian field may provide an antenna reference point location of a DL-PRS Resource Set relative to a trp-Location or trp- LocationCartesian location. If none of dl-PRS-ResourceSetARP or dl-PRS- ResourceSetARP-Cartesian is present, an antenna reference point location of a DL-PRS Resource Set may coincide with the trp-Location or trp-LocationCartesian location. An nr-IntegrityDL-PRS-ResourceSetARP-LocationBounds field may provide a mean or standard deviation ARP of a location error bound of a DL-PRS Resource Set of an overbounding model that bounds the antenna reference point location error of a DL-PRS Resource Set. The nr-IntegrityDL-PRS-ResourceSetARP-LocationBounds field may include one or more sub-fields units, including a meanLocationErrorBound or stdDevLocationErrorBound associated with an nr-IntegrityTRP-LocationBounds field. A dl-PRS-Resource-ARP-List field may provide antenna reference point location(s) of a DL-PRS Resource(s) associated with a Resource Set of a TRP together with integrity information. If the dl-PRS-Resource-ARP-List field is absent, the antenna reference point location(s) of the DL-PRS Resources may coincide with the dl-PRS-Re source Set ARP location or dl-PRS-ResourceSetARP-Cartesian.

[0152] Some examples network settings of a transmit power or power integrity (e.g., of a PRS) may include one or more of the following. A beamPowerList field may provide a relative power between DL-PRS Resources for an angle given by azimuth and elevation. A first BeamPowerElement in a list may provide a peak power for an angle and may be defined as 0 decibels (dB) power (e.g., the first value may be set to ‘0’ by a location server). One or more remaining BeamPowerElements in the list may provide a relative DL-PRS Resource power relative to a first element in the list. An nr-dl-prs- RelativePower field, except for a first element in a beamPowerList, may provide a relative power of a DL-PRS Resource, relative to a first element in the beamPowerList. For the first element in beamPowerList, the nr-dl-prs-RelativePower field may provide a peak power for an angle normalized to 0 dB. The nr-dl-prs-RelativePower field may have a scale factor 1 dB, or a range of 0 ot -30 dB. An nr-dl-prs-RelativePowerFine field may provide a relatively finer granularity for the nr-dl-prs-RelativePower. A total relative power of the DL-PRS Resource may be given by nr-dl-prs-RelativePower + nr- dl-prs-RelativePowerFine. The nr-dl-prs-RelativePowerFine may have a scale factor of 0.1 dB or a range 0 to -0.9 dB. For a first element in beamPowerList, the nr-dl-prs- RelativePowerFine field may not be utilized in some examples. An nr- IntegrityBeamPowerBounds field may specify a mean or a Standard Deviation beam power error bound for an overbounding model that bounds the beam power error. If the nr-IntegrityBeamPowerBounds field is absent, the nr-IntegrityBeamlnfoBounds for an instance of the beamPowerList may be the same as nr-IntegrityBeamlnfoBounds of a previous instance in the beamPowerList. If integrity bounds are provided, the nr- IntegrityBeamPowerBounds field may be included in a first instance of the beamPowerList. A meanBeamPower field may specify a Mean Beam Power Error bound, which may be a mean value for an overbounding model that bounds the beam power error of the DL-PRS Resources. The bound may be meanBeamPower + K * stdDevBeamPower or may be such that an associated probability to be exceeded may be lower than IRaiiocation for ir-Minimum < IRaiiocation < ir-Maximum, where K = normInv(IRaiiocation / 2) and ir-Minimum, where irMaximum may be provided in an IE NR-IntegrityServiceParameters. IRaiiocation may be a fraction of a Target Integrity Risk that represents an integrity risk budget available. The meanBeamPower may have a scale factor of 0.1 dB or a range of 0-12.7 dB. A stdDevBeamPower field may specify a Standard Deviation Beam Power Error bound, which may be a standard deviation for anAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO48 overbounding model that bounds the beam power error of DL-PRS Resources. The stdDevBeamPower field may have a scale factor of 0.1 degrees or a range 0-12.7 dB.
[0153] Examples of network settings of beam angles, shapes, or integrity (e.g., of a PRS), may include one or more of the following. An nr-TRP-BeamAntennaAngles field may provide a relative power between DL-PRS Resources per angle per TRP. If the nr- TRP-BeamAntennaAngles field is absent and the field associated-DL-PRS-ID is present, the nr-TRP-BeamAntennaAngles for a TRP may be obtained from nr-TRP- BeamAntennaAngles of an associated TRP. A dl -PRS -Beaminfo Set field may provide DL-PRS beam information for each DL-PRS Resource of a DL-PRS Resource Set associated with a TRP. If the dl-PRS-BeamlnfoSet field is absent and a field associated- DL-PRS-ID is present, the dl-PRS-BeamlnfoSet for a TRP may be obtained from a dl- PRS-BeamlnfoSet of an associated TRP. A dl-PRS-Azimuth field may specify an azimuth angle of a boresight direction in which DL-PRS Resources associated with a DL-PRS Resource ID in the DL-PRS Resource Set may be transmitted. For a Global Coordinate System (GCS), an azimuth angle may be measured counter-clockwise from geographical North. For a Local Coordinate System (LCS), an azimuth angle may be measured counter-clockwise from an x-axis of the LCS. The dl-PRS-Azimuth may have a scale factor of 1 degree or a range of 0 to 359 degrees. A dl-PRS-Azimuth-fine field may provide a relatively finer granularity for the dl-PRS-Azimuth. A total azimuth angle of a boresight direction may be given by dl-PRS-Azimuth + dl-PRS-Azimuth- fine. The dl-PRS-Azimuth-fine field may have a scale factor of 0.1 degrees or a range 0 to 0.9 degrees. A dl -PRS -Elevation field may specify an elevation angle of a boresight direction in which DL-PRS Resources associated with a DL-PRS Resource ID in a DL- PRS Resource Set may be transmitted. For a Global Coordinate System (GCS), an elevation angle may be measured relative to zenith and positive to the horizontal direction (e.g., elevation of 0 degrees may point to zenith, or 90 degrees may point to a horizon). For an LCS, an elevation angle may be measured relative to a z-axis of the LCS (e.g., an elevation of 0 degrees may point to a z-axis, or 90 degrees may point to an x-y plane). The dl -PRS -Elevation field may have a scale factor of 1 degree or a range of 0 to 180 degrees. A dl-PRS-Elevati on-fine field may provide a relatively finer granularity for the dl-PRS-Elevati on. A total elevation angle of a boresight direction may be given by dl-PRS-Elevati on + dl-PRS-Elevation-fine. The dl-PRS-Elevation-fineAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO49 field may have a scale factor of 0.1 degrees or a range of 0 to 0.9 degrees. An nr- IntegrityBeamlnfoBounds field may provide an overbounding model that bounds spatial direction information of DL-PRS Resources. If the nr-IntegrityBeamlnfoBounds field is absent, an nr-IntegrityBeamlnfoBounds for an instance of the DL-PRS- BeamlnfoElement may be the same as the nr-IntegrityBeamlnfoBounds of a previous instance of the DL-PRS-BeamlnfoElement in DL-PRS-BeamlnfoResourceSet.

[0160] The one or more network settings may relate to communication or measurement of reference signaling used in association with an AI / ML-basedAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO53 positioning procedure. For example, one or more network nodes may transmit one or more reference signals to the wireless device 415, which the wireless device 415 may utilize to perform an AI / ML-based positioning procedure.
[0161] A positioning procedure may be one or more operations for estimating a location of a device (e.g., the wireless device 415 or a UE). For instance, a positioning procedure may include one or more operations of A-GNSS positioning, OTDOA positioning, E-CID positioning, sensor-based 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, 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, 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 procedures are described with reference to FIG. 21.
[0162] As used herein, the term “AI / ML-based positioning procedure” may refer to a positioning procedure performed with an Al model or ML model. An “AI / ML-based positioning procedure” may refer to direct AI / ML (D-AI / ML) positioning or assisted AI / ML positioning (A-AI / ML). An “AI / ML model” for positioning may refer generally to a physical AIML 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 procedure” may refer to a positioning procedure performed without an Al model or ML model. AI / ML-based positioning procedures may improve positioning accuracy.
[0163] A non-AI / ML-based positioning procedure may include one or more positioning 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, sensor-based positioning, WLAN-based positioning,Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO54Bluetooth-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 performed without the use of an AI / ML technique or model may be examples of a non-AI / ML-based positioning procedure.
[0164] An AI / ML-based positioning procedure may include one or more positioning 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, 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 performed with the use of an AI / ML technique(s) or model(s) may be examples of an AI / ML-based positioning procedure. For instance, an Al model may be trained to model one or more operations of a positioning 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.
[0165] A position may be information or data indicating a point, area, or region where an object (e.g., the wireless device 415) is located. A location may be expressed as coordinates (e.g., latitude, 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.
[0166] A measurement may be measured, generated, calculated, inferred, or predicted based on one or more samples, 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 qualityAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO55 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), or reception-to- transmission (Rx-Tx) time difference, among other examples. In some examples, a measurement may be data or an indicator that indicates one or more of the aforementioned values.
[0167] 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 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 positioning reference signal (PRS), a sounding reference signal (SRS), a demodulation reference signal (DMRS), or a tracking reference signal (TRS), among other examples.
[0168] The measurement s) may be processed to generate input (e.g., input data) to an AI / ML model, to generate training data (e.g., a training dataset), or may be utilized by an AI / ML model to generate an estimated (e.g., predicted) position or other measurements. Examples of input data, predicted measurements, and positions (e.g., locations) are provided with reference to FIG. 23A and FIG. 23B. In some aspects, an indication of one or more measurements or positions (e.g., one or more predicted 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.,Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO56 receive) an indication of one or more predicted measurements or positions based on the one or more processing operations associated with AI / ML.
[0169] In some examples, one or more AI / ML models may be stored or processed on the wireless device 415 (e.g., a UE or a network node) or on the network entity 405 (e.g., a network node or a location server). Examples of locations where an AI / ML model may be stored or processed are provided with reference to FIG. 24. One or more of the techniques described herein may be utilized to control (e.g., activate, deactivate, select, switch, transition to, or transition from) one or more AI / ML models.
[0170] In some aspects, the one or more network settings may impact reference signaling or AI / ML-based positioning procedure performance. For instance, one or more network settings may affect the accuracy, reliability, correspondence, or alignment between AI / ML training and prediction (e.g., inference). In some examples, an AI / ML model may be trained in correspondence with one or more network settings. If the one or more network settings change, AI / ML model performance may be reduced. Because the one or more network settings may impact reference signaling or AI / ML-based positioning procedure performance, it may be helpful to maintain a correspondence between an AI / ML-based positioning procedure and the network setting(s) utilized during training of the AI / ML-based positioning procedure (e.g., AI / ML model or function). The one or more identifiers described herein may be utilized to establish a correspondence with one or more AI / ML-based positioning procedures, or to control one or more AI / ML-based positioning procedures (e.g., perform LCM) to maintain a correspondence between one or more AI / ML-based positioning procedures and network settings, while avoiding an explicit indication of the network setting(s).
[0171] The one or more network settings may be associated with one or more identifiers. An identifier may be a value, code, signal, index, or other information. In some examples, each of the one or more identifiers may be associated with one or more network settings of a network node (e.g., base station, gNB, TRP, or positioning reference unit (PRU). For instance, an identifier may represent or correspond to one or more network settings. In some approaches, the network entity 405 may include (e.g., store) a mapping, database, table (e.g., look-up table), list, array, index, tree, or other data structure indicating the association between the one or more of the identifiers and the one or more network settings (e.g., values or parameters of the network setting(s)).Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO57In some approaches, the one or more identifiers may not indicate actual quantities or values of the network setting(s). In some examples of the techniques described herein, an identifier that is associated with one or more network settings may not uniquely identify an AI / ML model or may not be an AI / ML model identifier (e.g., may not be an identifier that is specific to one AI / ML model).
[0172] In some examples, the network entity 405 (e.g., location server or LMF) may provide the wireless device 415 with one or more identifiers associated with one or more network settings. In some approaches, an indication of the one or more identifiers may be communicated (e.g., output, transmitted, obtained, or received) via signaling associated with an assistance data provision procedure or via a broadcast of assistance data. For example, signaling for providing the identifier(s) may be part of a “provide assistance data” procedure. Additionally, or alternatively, signaling for providing the identifier(s) may be part of a broadcast of assistance data signaling. For instance, the identifier(s) may be communicated via a positioning system information block (SIB).
[0173] In some aspects, one or more AI / ML-based positioning procedures (e.g., AI / ML model(s) or AI / ML function(s), among other examples) may correspond to one or more identifiers. For instance, the wireless device 415 may include (e.g., store) a mapping, database, table (e.g., look-up table), list, array, index, tree, or other data structure indicating a correspondence between one or more of the identifiers and one or more of the AI / ML-based positioning procedures (that may be impacted by one or more network settings or groups of network settings).
[0174] The wireless device 415 (e.g., UE) may communicate, with the network entity 405, information 440 related to at least one grouping type corresponding to a group of one or more network settings. For example, the wireless device 415 may transmit the information 440 to the network entity 405, or may receive the information 440 from the network entity 405. A grouping type may be a rule or manner for grouping network settings (e.g., whether network settings may be grouped individually or plurally or another condition(s) for grouping network settings as described herein). In some examples, as described herein, the one or more network settings may relate to communication or measurement of reference signaling used in association with an AI / ML-based positioning procedure, or the one or more network settings may beAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO58 associated with one or more identifiers. In some aspects, one or more identifiers may correspond to one or more grouping types.
[0175] Examples of grouping types may include a first grouping type or a second grouping type. The first grouping type may allow or provide one or more groups, where a group includes an individual or single network setting (e.g., an individual or single network condition or an individual or single network additional condition). For instance, each identifier of the one or more identifiers may correspond to one respective network setting in accordance with the first grouping type of the at least one grouping type. In some examples of the first grouping type, an identifier may correspond to a network setting (e.g., may explicitly correspond to a network condition or additional condition).
[0176] One or more approaches may be utilized for mapping one or more identifiers (e.g., one or more identifiers associated with one or more network settings) to one or more of the grouping types. In a first mapping for the first grouping type, for example, an individual identifier may be associated with a network setting or condition (e.g., with a single network setting or condition).
[0177] In some examples of a second mapping for the first grouping type, a superset identifier may indicate a set of identifiers associated with the one or more network settings in the group. For instance, a superset identifier (e.g., single superset identifier) may be utilized, where the superset identifier may include one or more portions. Each portion may correspond (e.g., explicitly correspond) to an individual network condition or additional condition. For instance, a superset identifier (e.g., one identifier) may correspond to a set of network settings or conditions (e.g., a set of one or more single network condition(s)), where each part of the identifier respectively corresponds to each network setting or condition. In some examples, the wireless device 415 may have (e.g., store) information indicating the portions or parts of the superset identifier or one or more boundaries corresponding to the portions or parts. The information may be provided (e.g., signaled) by a network entity (e.g., the network entity 405) or may be stored by the wireless device 415. For instance, the correspondence between the portions and the identifiers may be explicit to a UE. In some approaches, each identifier of the set of identifiers may be indicated by a respective set of bits that corresponds to one network setting. The superset identifier may be indicated by each respective set of bits. Examples of the first grouping type are provided with reference to FIG. 6.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO59
[0178] The second grouping type may provide one or more groups, where a group includes multiple network settings (e.g., multiple network conditions or multiple network additional conditions). An identifier may correspond to the multiple network settings in the group. For instance, the identifier of the one or more identifiers may correspond to multiple network settings in accordance with the second grouping type of the at least one grouping type.
[0179] In a third mapping for the second grouping type, an identifier (e.g., an identifier associated with one or more network settings) may correspond to a multiple network settings (e.g., a set of network settings or conditions). In a fourth mapping for the second grouping type, an identifier (e.g., an identifier associated with one or more network settings) may correspond multiple network settings (e.g., a set of network settings or conditions), where portions or parts of the identifier may correspond to one or more network settings or conditions (e.g., sets of network settings).
[0180] In some examples of the second grouping type, an identifier may be agnostic to one or more underlying individual network conditions or additional conditions. The identifier may correspond to a group of network settings or conditions without distinguishing between the network settings or conditions. For instance, a group of network settings (e.g., network conditions or additional conditions) may be indicated using an associated identifier (without explicitly indicating how the identifier maps to the network settings individually, for example). In some approaches, a multi-group identifier may be utilized. A multi-group identifier may be an identifier that identifies two or more groups of one or more network settings, or may be an identifier that corresponds to, indicates, or includes identifiers of two or more groups of one or more network settings (e.g., where one or more of the identifiers corresponds to the second grouping type, or where one or more of the identifiers has no direct mapping to an individual network setting, but to multiple settings or a group of settings). For instance, a multi-group identifier of the one or more identifiers may be indicated by a set of bits corresponding to the multiple network settings without an indicated mapping between the set of bits and the multiple network settings. Examples of the first grouping type are provided with reference to FIG. 6.
[0181] In some approaches, the information 440 may be, or may include, an indication of one or more grouping types (e.g., candidate grouping type(s)), capabilityAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO60 information (relating to a grouping type(s), for instance), or availability information indicating an availability of at least one grouping type, among other examples.
[0182] In some examples, to communicate the information 440 related to the at least one grouping type, the network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive), a first signal indicating candidate grouping types. At least one of the candidate grouping types may be mapped to at least one of the one or more identifiers. For instance, the first signal (e.g., long-term evolution positioning protocol (LPP) signaling) may be utilized for the wireless device 415 (e.g., UE) to receive, from the network entity 405 (e.g., LMF), one or more indications of candidate grouping types (e.g., potential grouping types, such as the first grouping type or second grouping type) of network settings (e.g., conditions) or mapping(s) (e.g., the first mapping, second mapping, third mapping, or fourth mapping, among other examples) to the one or more identifiers.
[0183] In some aspects, the first signal may be (or may include) at least a portion of a location request message, at least a portion of a unicast assistance data message, or at least a portion of a broadcast assistance data message. For instance, the first signal (e.g., information indicating one or more candidate grouping types) may be part of a location request message, part of an assistance data delivery message, may be communicated via unicast, may be communicated via broadcast (e.g., via a positioning system information block (posSIB) or a new posSIB type for an associated identifier). In some examples, the network entity 405 (e.g., LMF) may output (e.g., transmit), or the wireless device 415 (e.g., UE) may obtain (e.g., receive), the first signal based on a request communicated from the wireless device 415 to the network entity 405.
[0184] In some approaches, the wireless device 415 may output (e.g., transmit), or the network entity 405 may obtain (e.g., receive), a request for the first signal indicating the candidate grouping types. The first signal may be received based on the request. For instance, the request may be signaling (e.g., LPP signaling) for the wireless device 415 (e.g., UE) to request one or more indications from the network entity 405 (e.g., LMF) for one or more potential grouping types of network settings (e.g., conditions) or mapping(s) (e.g., the first mapping, second mapping, third mapping, or fourth mapping, among other examples) to one or more associated identifiers. In some approaches, theAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO61 request may be (e.g., may be communicated as) part of an assistance data request message.
[0185] In some approaches, to communicate the information 440 related to the at least one grouping type, the wireless device 415 may output (e.g., transmit), or the network entity 405 may obtain (e.g., receive), capability information indicating a capability of the wireless device 415 (e.g., UE) to utilize the at least one grouping type. For instance, signaling (e.g., LPP signaling) may be utilized for the wireless device 415 to provide the network entity 405 (e.g., LMF) one or more indications related to wireless device capabilities for potential grouping types (e.g., candidate grouping types) of network settings (e.g., conditions) or mapping(s) (e.g., the first mapping, second mapping, third mapping, or fourth mapping, among other examples) to one or more identifiers. In some approaches, the capability information may indicate whether the wireless device 415 supports receiving information in accordance with a first grouping type (e.g., individual network settings grouping type), in accordance with a second grouping type (e.g., multiple network settings grouping type), or multiple (e.g., both) grouping types. Additionally, or alternatively, the capability information may indicate whether the wireless device supports one or more network settings (e.g., different network conditions). In some examples, the capability information may be included in (e.g., communicated as) part of a capability provide message.
[0186] In some examples, the network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive) a request for the capability information. The capability information may be communicated (e.g., transmitted or received) based on the request (e.g., based on an LMF request to a UE).
[0187] In some aspects, to communicate the information 440 related to the at least one grouping type, the network entity 405 may output (e.g., transmit), or the wireless device 415 may obtain (e.g., receive) availability information indicating an availability of the at least one grouping type. For instance, the signaling may indicate an availability of one or more grouping types for network settings (e.g., conditions) when indicated using an associated identifier. The availability of the at least one grouping type may include an availability of a first grouping type for individual network setting grouping, a second grouping type for multiple network setting grouping, or a combination thereof. For instance, the availability information may indicate an availability of the firstAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO62 grouping type (e.g., individual network setting grouping), the second grouping type (e.g., multiple network setting grouping), or the first grouping type and the second grouping type. In some examples, a network setting (e.g., condition) may be grouped in accordance with one or more grouping types (e.g., the first grouping type and the second grouping type).
[0188] In some approaches, the information 440 related to the at least one grouping type may indicate one or more grouping types corresponding to at least one of the one or more network settings. For instance, signaling (e.g., information 440) may indicate detailed grouping types of network settings (e.g., conditions) when indicated using an associated identifier. In an example, network settings (e.g., conditions) of TRP location information and PRS Tx power may be indicated as corresponding to the first grouping type (e.g., individual grouping type) and the second grouping type (e.g., multiple grouping type). In another example, network settings (e.g., conditions) of PRS beam shape, PRS beam angle, and TRP relative time difference may be indicated as corresponding to the second grouping type (e.g., multiple grouping type). In yet another example, a network setting (e.g., condition) of TRP Tx timing error may be indicated as corresponding to the first grouping type (e.g., individual grouping type for one network setting). In some approaches, if the network entity 405 (e.g., LMF) supports (e.g., only supports) the second grouping type (e.g., multiple grouping type) when indicated with an associated identifier, another type may be signaled indicating that at least some (e.g., all) network settings (e.g., conditions) correspond to the second grouping type. For example, signaling this type may avoid signal all of network settings (e.g., in one list).
[0189] In some examples, the wireless device 415 may communicate, with the network entity 405, an indication of the identifier associated with the group of one or more network settings. For instance, signaling of an identifier (associated with a network setting(s), for example) may have one or more formats of correspondence to the network setting(s) (e.g., condi tion(s)).
[0190] In some aspects, the indication of the identifier may include a set of bits associated with one network setting, a set of bits comprising subsets of bits associated with respective network settings, a set of bits associated with multiple network settings, or a set of bits comprising subsets of bits associated with respective groups of one or more network settings. For example, the indication of the identifier (e.g., signaling) mayAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO63 include one or more of the following formats: a codeword or bitmap for a network setting (e.g., individual network condition); a codeword or bitmap for Ns network settings (e.g., Ns individual network conditions), where each network setting may be indicated as a sub-codeword or sub-bitmap of the codeword or bitmap; a codeword or bitmap for multiple network settings (e.g., multiple network conditions); or a codeword or bitmap for Ng multiple network settings (e.g., conditions), where each network setting (e.g., condition) may be indicated as a sub-codeword or sub-bitmap of the codeword or bitmap.
[0191] In some approaches, the wireless device 415 may communicate, with the network entity 405, data indicating a characteristic of the indication of the identifier. The characteristic may include a size of a subset of bits corresponding to one or more network settings, a boundary of a subset of bits corresponding to one or more network settings, an order of subsets of bits corresponding to one or more network settings, or a combination thereof. For instance, a size(s) or boundary(ies) for sub-codewords or subbitmaps may signaled (e.g., may be part of the signaling). Additionally, or alternatively, an order or mapping of a network setting (e.g., individual network condition) or multiple network settings (e.g., conditions) to sub-codewords or sub-bitmaps may be signaled (e.g., may be part of the signaling).
[0192] In some examples, a second grouping type may correspond to one or more network settings for which a first grouping type or a second grouping type is not indicated. For instance, one or more network settings (e.g., network condition(s)) may correspond to a second grouping type (e.g., multiple grouping type by default) unless a first grouping type (e.g., individual grouping type) or a second grouping type (e.g., multiple grouping type) is indicated. In some aspects, a first identifier may not correspond to a network setting for which a first grouping type or a second grouping type is not indicated. For example, a network setting (e.g., network condition) may have no correspondence to an identifier if the network setting is not listed under the first grouping type or second grouping type. In some approaches, a first identifier may not correspond to a network setting for which a first grouping type or a second grouping type is not indicated based on a communication of the identifier or the at least one grouping type. For instance, a network setting (e.g., network condition) may have no correspondence to an identifier if the network setting is not listed under a first groupingAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO64 type or second grouping type and at least one first grouping type or second grouping type is provided.
[0193] In some aspects, one or more of the signals or signaling described herein may be performed in accordance with a specification. In some approaches, the capability information signaling or request signaling may be performed (or may not be performed). In some examples, the network entity 405 (e.g., LMF) may implement (or may not implement) one or more requests (e.g., the request signaling) from the wireless device 415 (e.g., UE). Additionally, or alternatively, one or more of the operations or signaling described herein may be subject to wireless device 415 (e.g., UE) capability.
[0194] In some approaches, the network entity 405 may output (e.g., transmit), or the wireless device 415 may receive, an indication of one or more identifiers. In some approaches, the indication may be communicated via downlink control information (DCI), an RRC message, a medium access control-control (MAC-CE) message, LTE positioning protocol (LPP) signaling, or NR positioning protocol A (NRPPa) signaling, or assistance data, among other examples.
[0195] In some examples, the wireless device 415 may perform an operation to control the AI / ML-based positioning procedure based at least in part on an identifier associated with the one or more network settings in the group corresponding to the at least one grouping type. In some aspects, the operation associated with the AI / ML- based positioning procedure may include inputting at least one of the one or more identifiers to an AI / ML model during training. For example, an identifier may be utilized as AI / ML model input during training. The identifier may be utilized as an input to assist the AI / ML model in training to infer a position with increased accuracy. Additionally, or alternatively, an AI / ML model may be trained where different identifiers may be input to enable the AI / ML model to be trained to adapt to different network settings corresponding to different identifiers.
[0196] In some approaches, the operation may include mapping at least one of the one or more identifiers as metadata to an AI / ML model. For instance, the identifier(s) may be stored or linked to one or more AI / ML models as metadata. In some aspects, the identifiers may be utilized as metadata to select, activate, or switch to an AI / ML modelAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO65(from a set of AI / ML models, for instance) with metadata corresponding to an identifier (e.g., an identifier) indicated by the network entity 405.
[0197] In some examples, the operation may include training an AI / ML model based on at least one of the one or more identifiers. For instance, the identifier(s) may be utilized to train one or more AI / ML models for positioning. For instance, one or more of the identifiers may be utilized in association with (e.g., as metadata of) one or more AI / ML models, may be utilized as input to the one or more AI / ML models, may be utilized to sort collected data, or may be utilized to associate collected data with one or more AI / ML models. For instance, the wireless device 415 may collect data (e.g., one or more measurements of reference signals) in one or more periods when different identifiers are in use or indicated by the network entity 405. The collected data in each of the periods may be labeled, stored, or input for training each of the AI / ML models corresponding to each of the identifiers.
[0198] In some aspects, the wireless device 415 may transmit, or the network entity 405 or a server (e.g., an over-the-top (OTT) server) may obtain (e.g., receive) a message indicating at least one of the one or more identifiers associated with the one or more network settings of the network node. For example, one or more of the identifiers may be reported to an OTT server.
[0199] In some approaches, the one or more identifiers may be utilized in one or more aspects on the wireless device 415 (e.g., UE). For example, the operation associated with the AI / ML-based positioning procedure may include determining whether the wireless device 415 supports the AI / ML-based positioning procedure based at least in part on at least one of the one or more identifiers. In some aspects, one or more of the identifiers may be utilized by the wireless device 415 (e.g., UE) to determine (e.g., verify) whether the wireless device 415 may support AI / ML positioning. The wireless device 415 may indicate to the network entity 405 (e.g., LMF) whether the wireless device 415 supports AI / ML positioning based on whether the model metadata for a corresponding identifier matches an identifier indicated by the network entity 405. In some examples, the wireless device 415 may supports AI / ML- based positioning or may not support AI / ML positioning. In some examples, “support” of an AI / ML-based positioning procedure(s) may mean that the corresponding AI / ML- based positioning procedure(s) (e.g., the AI / ML positioning model(s) orAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO66 functionality(s)) may be supported whether or not the AI / ML-based positioning procedure(s) is downloaded, compiled, validated, verified, ready, or available at the wireless device 415. Depending on the determination, the wireless device 415 may determine whether to activate or deactivate AI / ML-based positioning.
[0200] In some examples, the operation may include controlling an AI / ML model based on at least one of the one or more identifiers. For instance, one or more of the identifiers may be utilized by the wireless device 415 (e.g., UE) to select or switch an AI / ML model for positioning (e.g., after training, during runtime, or during prediction, among other examples).
[0201] In some approaches, the operation may include inputting at least one of the one or more identifiers to an AI / ML model. For instance, one or more of the identifiers may be utilized by the wireless device 415 (e.g., UE) as model input during inference (e.g., to produce an inferred measurement s) or position(s)).
[0202] In some aspects, the wireless device 415 may transmit, or the network entity 405 may obtain (e.g., receive) an indication of the operation associated with the AI / ML- based positioning procedure. For instance, the wireless device 415 (e.g., UE) may utilize LPP signaling to indicate to the network entity 405 (e.g., LMF) whether the wireless device 415 has applied (or will apply) model selection or switching based on one or more of the identifiers. Additionally, or alternatively, the wireless device 415 may transmit information indicating (e.g., recommending) activation or deactivation of AI / ML positioning.
[0203] In some examples, the indication of the operation may indicate controlling an AI / ML model based at least in part on at least one of the one or more identifiers. For instance, the wireless device 415 may determine whether to perform an operation based on the indication of the one or more identifiers (e.g., in a case that the wireless device 415 includes an AI / ML-based positioning procedure corresponding to one or more of the indicated identifiers). The wireless device 415 may transmit an indication of the operation (e.g., activation, deactivation, switching, selecting, or transitioning to a non- AI / ML-based positioning procedure).
[0204] In some examples, network settings may be referred to as conditions, which may be divided into two categories: network-side additional conditions or wirelessAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO67 device-side additional conditions. For an AI / ML-enabled feature, additional conditions may refer to one or more aspects for the training of the model (but which may not be a part of wireless device 415 capability for the AI / ML-enabled feature).
[0205] For inference for wireless device-side models, to ensure correspondence or alignment between training and inference regarding one or more network-side additional conditions, one or more of the following options may be utilized: model identification to achieve alignment on the network-side additional condition between network-side and wireless device-side, model training at the network and transfer to wireless device 415, where the model has been trained under the additional condition, information or indication on network-side additional conditions provided to the wireless device 415, correspondence or alignment assisted by monitoring (by the wireless device 415 or network, the performance of wireless device-side candidate models or functionalities to select a model or functionality.
[0206] One or more options may be utilized for model identification. In a first option, model identification with data collection related configuration(s) or indication(s) may be performed. In a second option, model identification may be performed with dataset transfer. In a third option, model identification may be performed in a model transfer from network to the wireless device 415. In a fourth option, model identification may be carried out via standardization of reference models (for CSI compression). In a fifth option model identification may be performed via model monitoring.
[0207] In the first option, (e.g., model identification with data collection related configuration(s) or indication(s)) one or more of the following aspects may be utilized. A relationship between a model identifier and data collection related configuration(s) or indication(s) may be utilized. Information transmitted from the network to the wireless device 415 may be utilized. Information transmitted from the wireless device 415 to the network may be utilized.
[0208] In some approaches, wireless device-sided AI / ML model(s) may be developed (e.g., trained or updated) at the wireless device 415. One or more of the following aspects may be utilized in some examples. For data collection, the network signals a data collection related configuration(s) and an associated identifier(s). As usedAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO68 herein, an associated identifier may refer to an identifier associated with one or more network settings. The associated identifiers may be utilized in relation with networksided additional conditions. The wireless device 415 may collect the data corresponding to the associated identified s). One or more AI / ML models may be developed (e.g., trained or updated) at the wireless device 415 side based on the collected data corresponding to the associated identifier(s).
[0209] The wireless device 415 may (to facilitate AI / ML model inference) report information of the one or more AI / ML models corresponding to the associated identifiers to the network. A model identifier may be determined or assigned for each AI / ML model. In some examples, the reported information may indicate a relationship between the model identifier(s) and the associated identifier(s), how the model identifier(s) are determined or assigned (e.g., the network assigns the model identifier, the wireless device 415 assigns or reports the model identifier, or the associated identifier(s) may be assumed as a model identified s) (where a model identifier for each AI / ML model may not be determined or utilized), or the model identifier is determined via one or more rules. One or more of these procedures may be utilized with interaction of associated identifiers between the wireless device 415 and network for resolving the correspondence issue without model identification. Regarding the associated identifier, the wireless device 415 may assume that network-side additional conditions with the same associated identifier may be utilized (e.g., are reliable) at least within one or more cells in some approaches.
[0210] From a network perspective, for a wireless device part of a two-sided model may be utilized in the following example of model identification. A dataset may be transferred from the network or network-side to the wireless device 415 or wireless device-side via signaling. A wireless device part of the two-sided model(s) may be developed based on the dataset. The wireless device may report information of the wireless device part of the two-sided model(s) corresponding to the dataset to the network. A model may be trained on the network side or on the wireless device 415 side first.
[0211] In some approaches, the associated identifier may be utilized for training or inference correspondence or alignment for an AI / ML one or more beam management use cases. For instance, an associated identifier may be utilized to ensureAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO69 correspondence or alignment for network-side additional condition(s) across training and inference for a wireless device-sided model for beam management cases, where the network-side additional condition may impact the training and inference correspondence for multiple (e.g., different) sets of beams. In some examples, the associated identifier may be communicated within a CSI framework or outside of the CSI framework. In some approaches, the associated identifier may be utilized to control an AI / ML-based positioning procedure based on performance monitoring.
[0212] In some approaches, the associated identifier may be utilized to ensure a correspondence or alignment for training and inference for AI / ML-based positioning. For AI / ML based positioning Case 1 and Case 2a, for instance, the associated identifier may be utilized to coordinate network-side additional condition(s) (e.g., network settings) to ensure the correspondence or alignment between training and inference. In some cases, network-side additional conditions with the same associated identifier may be utilized within a cell, a TRP, or an area.
[0213] FIG. 5 shows an example of a wireless communications system 500 that supports grouping types for network settings and associated identifiers for AI / ML-based positioning in accordance with one or more aspects of the present disclosure. The wireless communications system 500 may include a wireless device 515, which may be an example of a UE 115, UE 115-a, UE 115-b, or a wireless device 415, as described herein. The wireless communications system 500 may also include a network 505, which may be an example of a network node 105, gNB 255, ng-eNB 260, CU 160, CU 160-a, CU 160-b, DU 165, DU 165-a, DU 165-b, RU 170, RU 170-a, RU 170-b, the location server 185, LMF 265, external device 230, SLP 235, a network entity 405, or a combination thereof, as described herein.
[0214] As illustrated in FIG. 5, the network 505 (e.g., network entity) may include one or more identifiers 510-b, which may be associated with one or more network settings 520. The one or more network settings 520 may be included in a group 530. The group 530 may correspond to a grouping type. For instance, the one or more network settings 520 may be grouped in accordance with the first grouping type or the second grouping type described with reference to FIG. 4. The association(s) between the one or more identifiers 510-b and the one or more network settings 520 may be structured as described with reference to FIG. 4. Grouping the network settings 520 inAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO70 accordance with a grouping type(s) may allow one or more of the identifiers 510-b to be associated with one or more of the network settings 520, which may allow for more efficient signaling (e.g., reduced bandwidth usage for signaling) of identifier(s) for multiple network settings, or may enable changes to one or more network settings 520 without explicitly identifying changes to the group(s) of the network settings.
[0215] The wireless device 515 may include one or more identifiers 510-a. At least one of the one or more identifiers 510-a may correspond to (e.g., may match) at least one of the one or more identifiers 510-b. One or more of the identifiers 510-a may correspond to one or more AI / ML-based positioning procedures 525 (e.g., AI / ML model(s) or AI / ML function(s) for producing measurement information related to positioning). The correspondence between the one or more identifiers 510-a and the one or more AI / ML-based positioning procedures 525 may be structured as described with reference to FIG. 4.
[0216] In some examples of the techniques described herein, the network 505 may output (e.g., transmit), or the wireless device 515 may receive, an indication of the one or more identifiers 510-b, where one or more of the identifiers 510-b may be associated with the group 530 of one or more network settings 520 of a network node. The group 530 of one or more network settings 520 may relate to communication of reference signaling for one or more AI / ML-based positioning procedures 525 or for measurement of reference signaling for one or more AI / ML-based positioning procedures 525. The wireless device 515 may performing one or more operations associated with one or more AI / ML-based positioning procedures based on the one or more identifiers 510-b associated with the group 530 of one or more network settings 520. For instance, the wireless device 515 may store one or more identifiers 510-a that match the one or more indicated identifiers 510-b. The wireless device 515 may train one or more AI / ML models corresponding to one or more identifiers 510-a, may input the one or more identifiers 510-a to one or more AI / ML models for training or inference, may map one or more of the identifiers 510-a as metadata to the one or more AI / ML models, may determine whether the wireless device 515 supports one or more AIML-based positioning procedures 525 based on one or more of the identifiers 510-a, or may control one or more AI / ML-based positioning procedures 525 based on the one or more identifiers 510-a. The grouping type(s) may enable the wireless device 515 to controlAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO71 the AI / ML-based positioning procedure 525 for changes to individual or multiple network settings 520. For instance, one or more AI / ML models for positioning may be trained based on the grouping type or identified s) 510-a. Accordingly, when an identifier is indicated by the network 505, the wireless device 515 may change or control the AI / ML model, which may have been trained corresponding to a group 530 of the one or more network settings 520.
[0217] FIG. 6 shows an example of a diagram 600 that supports grouping types for network settings and associated identifiers for AI / ML-based positioning in accordance with one or more aspects of the present disclosure. The diagram 600 illustrates examples of a first grouping type 605 and of a second grouping type 625. The first grouping type 605 may be an example of the first grouping type described with reference to FIG. 4. The second grouping type 625 may be an example of the second grouping type described with reference to FIG. 4. Each of the network settings described with reference to FIG. 6 may be related to, or may impact, one or more AI / ML-based positioning procedures. For instance, the network settings may impact reference signaling or a correspondence between a network setting (on a network side, for instance) and an AI / ML-based positioning procedure (which may be partially or completely performed at a wireless device, for instance).
[0218] As illustrated in FIG. 6, the first grouping type 605 may provide for an identifier (e.g., a single or individual identifier) to be associated with a network setting (e.g., a single or individual network setting). In an example of a first mapping 610 for the first grouping type 605, network setting A is associated with identifier 1, network setting B is associated with identifier 2, network setting C is associated with identifier 3, network setting D is associated with identifier 4, and network setting E is associated with identifier 5. Each of the network settings may be grouped in accordance with the first grouping type 605. For instance, network setting A may be included in group I, network setting B may be included in group II, network setting C may be included in group III, network setting D may be included in group IV, or network setting E may be included in group V. In accordance with the first grouping type 605, each of the groups includes a network setting (e.g., an individual network setting). Accordingly, when an identifier is utilized (e.g., signaled between a network entity and a wireless device), theAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO72 identifier with the first grouping type 605 may indicate that a network setting (e.g., an individual network setting) is associated with the identifier.
[0219] In an example of a second mapping 615 for the first grouping type 605, network setting A is associated with identifier 1, network setting B is associated with identifier 2, network setting C is associated with identifier 3, network setting D is associated with identifier 4, and network setting E is associated with identifier 5. Each of the network settings may be grouped in accordance with the first grouping type 605. For instance, network setting A may be included in group I, network setting B may be included in group II, network setting C may be included in group III, network setting D may be included in group IV, or network setting E may be included in group V. In accordance with the first grouping type 605, each of the groups includes a network setting (e.g., an individual network setting). Accordingly, when an identifier is utilized (e.g., signaled between a network entity and a wireless device), the identifier with the first grouping type 605 may indicate that a network setting (e.g., an individual network setting) is associated with the identifier. As further illustrated in the second mapping 615, a superset identifier 620 may be utilized, where the superset identifier 620 corresponds to group VI, which includes the network settings of group I, group II, group III, group IV, and group V. An example of an expression of the superset identifier 620 is also provided as a set of bits, where five subsets of the bits respectively correspond to each of identifier 1, identifier 2, identifier 3, identifier 4, and identifier 5. The size or boundaries of the subsets of the bits may be established or indicated, which may provide a correspondence between respective network settings and subsets of bits of the superset identifier 620.
[0220] As illustrated in FIG. 6, the second grouping type 625 may provide for an identifier (e.g., a single or individual identifier) to be associated with multiple network settings. In an example of a third mapping 630 for the second grouping type 625, network setting A, network setting B, network setting C, network setting D, and network setting E are associated with identifier 1. The network settings may be grouped in accordance with the second grouping type 625. For instance, network setting A, network setting B, network setting C, network setting D, and network setting E may be included in group I. Accordingly, when an identifier is utilized (e.g., signaled between a network entity and a wireless device), the identifier with the second grouping type 625Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO73 may indicate that multiple network settings are associated with the identifier (without specifically indicating which network settings are associated with the identifier, for instance).
[0221] In an example of a fourth mapping 635 for the second grouping type 625, network setting A and network setting B are associated with identifier 1. Network setting C, network setting D, and network setting E are associated with identifier 2. Each of the network settings may be grouped in accordance with the second grouping type 625. For instance, network setting A and network setting B may be included in group I. Network setting C, network setting D, and network setting E may be included in group II. In accordance with the second grouping type 625, each of the groups includes multiple network settings. Accordingly, when an identifier is utilized (e.g., signaled between a network entity and a wireless device), the identifier with the second grouping type 625 may indicate that multiple network setting are associated with the identifier. As further illustrated in the fourth mapping 635, a multi -group identifier 640 may be utilized, where the multi-group identifier 640 corresponds to group I and group II, which includes the network settings of group I and group II. An example of an expression of the multi-group identifier 640 is also provided as a set of bits, where two subsets of the bits respectively correspond to each of identifier 1 and identifier 2. Because individual subsets of bits may not uniquely correspond to respective network settings, the multi-group identifier 640 may allow indicating multiple groups of network settings without uniquely corresponding to individual network settings.
[0222] FIG. 7 shows an example of a process flow 700 that supports grouping types for network settings and associated identifiers for AI / ML-based positioning in accordance with one or more aspects of the present disclosure. The process flow 700 may include a UE 115-c, which may be an example of a UE 115, UE 115-a, UE 115-b, wireless device 415, or wireless device 515, as described herein. The process flow 700 may also include a location server 185-a, which may be an example of the location server 185, LMF 265, external device 230, SLP 235, network entity 405, or network 505, as described herein.
[0223] In the following description of the process flow 700, the communications between the UE 115-c and the location server 185-a may be transmitted in a different order than the example order shown, or the operations performed by the UE 115-c or theAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO74 location server 185-a may be performed in different orders or at different times. One or more operations may be omitted from the process flow 700, or one or more other operations may be added to the process flow 700.

[0349] FIG. 21 shows an example of a wireless communications system 2100 that supports grouping types for network settings and associated identifiers for AI / ML-based positioning in accordance with one or more aspects of the present disclosure. Various positioning techniques are illustrated in the context of the wireless communications systems 2100. Some examples of the positioning procedures described herein may be performed in accordance with one or more aspects of the positioning techniques. While TRPs and UEs are provided in the examples illustrated in FIG. 21, 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 ofAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO109 positioning techniques include downlink-based positioning techniques, uplink-based positioning techniques, and downlink-and-uplink-based positioning techniques.
[0350] Examples of OTDOA or DL-TDOA 2105 are illustrated in FIG. 21. One or more of the OTDOA or DL-TDOA 2105 positioning techniques may be included in a downlink-based positioning procedure. In OTDOA or DL-TDOA 2105 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 TRPS). In some 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.
[0351] 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.
[0352] An example of UL-TDOA 2110 is illustrated in FIG. 21. One or more of the UL-TDOA 2110 positioning techniques may be included in an uplink-based positioning procedure. UL-TDOA 2110 may have some similarities to DL-TDOA 2105. The UL- TDOA 2110 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 theAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO110 corresponding timing offsets, the positioning device may estimate the location of the UE using TDOA.
[0353] An example of DL-AOD 2115 is illustrated in FIG. 21. One or more of the DL-AOD 2115 positioning techniques may be included in a downlink-based positioning procedure. In DL-AOD 2115, 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 positioning device. The positioning device may use the signal strength measurements of the multiple downlink transmit beams to determine the angle(s) (e.g., AOD1 and AOD2) 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).
[0354] An example of UL-AOA 2120 is illustrated in FIG. 21. One or more of the UL-AOA 2120 positioning techniques may be included in an uplink positioning procedure. In UL-AOA 2120, 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.
[0355] 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).
[0356] 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 receivedAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WOI l lRTT-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 time 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).
[0357] An example of multi-cell RTT 2125 is illustrated in FIG. 21. 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 2125, 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.
[0358] 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 2130 positioning techniques are illustrated in FIG. 21.
[0359] E-CID positioning techniques (not shown in FIG. 21) 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.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO112
[0360] 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 more 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.
[0361] 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.
[0362] 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 definedAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO113 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).
[0363] Various examples of sidelink positioning techniques are illustrated in FIG. 21. Sidelink positioning techniques may include positioning techniques that are based on sidelink communication (e.g., based exclusively on sidelink communication or based on sidelink communication jointly with other communication(s), such as Uu interface communication).
[0364] A first example of sidelink positioning 2135 is illustrated in FIG. 21. In the first example of sidelink positioning 2135, 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)).
[0365] A second example of sidelink positioning 2140 is illustrated in FIG. 21. In the second example of sidelink positioning 2140, 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.
[0366] A third example of sidelink positioning 2145 is illustrated in FIG. 21. The third example of sidelink positioning 2145 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 2145, 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 relativeAttorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO114 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).
[0367] A fourth example of sidelink positioning 2150 is illustrated in FIG. 21. The fourth example of sidelink positioning 2150 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 fourth example of sidelink positioning 2150, 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.
[0368] An example of relay positioning 2155 is illustrated in FIG. 21. In the example of relay positioning 2155, 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.
[0369] An example of joint positioning 2160 is illustrated in FIG. 21. In the example of joint positioning 2160, 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. 21, 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.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO115
[0370] 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. 21. 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 or more wireless communications systems 2100, such as LTE and NR, where NR may support sidelink communications.
[0371] FIG. 22 shows an example of a node diagram 2200 that supports grouping types for network settings and associated identifiers for AI / ML-based positioning 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.
[0372] 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.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO116
[0373] 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 regression include multiple linear regression (e.g., finding a plane of best fit) and polynomial regression (e.g., finding a curve of best fit).
[0374] 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.
[0375] 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.
[0376] 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.Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO117
[0377] 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.
[0378] The Al model illustrated in FIG. 22 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 hidden 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. 22, 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.
[0379] In some aspects, the Al model illustrated in FIG. 22 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).
[0380] 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,Attorney Docket No. PB0021GR.WO (114958.5216)Qualcomm Ref. No. 2407955WO118RTT 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.
[0381] In some examples, ground truth data may indicate one or more measurements or values (e.g., AOA measurements, AOD measurements, TDOA measurements, RTT measurements, LOS angle(s), or other values) 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, CSLRS, DMRS, or TRS, among other examples), signal data (e.g., signal strength data, RSRP data, RSSI 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...
