SUBSAMPLE CONFIGURATION FOR POSITIONINGCROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Non-Provisional Patent Application Serial No. 18 / 582,542, entitled “SUBSAMPLE CONFIGURATION FOR POSITIONING” and filed on February 20, 2024, which is expressly incorporated by reference herein in its entirety.TECHNICAL FIELD

[0002] The present disclosure relates generally to communication systems, and more particularly, to a wireless positioning system.INTRODUCTION

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0004] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3 GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G LongTerm Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.BRIEF SUMMARY

[0058] The following description is directed to examples for the purposes of describing innovative aspects of this disclosure. However, a person having ordinary skill in the art may recognize that the teachings herein may be applied in a multitude of ways. Some or all of the described examples may be implemented in any device, system or network that is capable of transmitting and receiving radio frequency (RF) signals according to one or more of the Institute of Electrical and Electronics Engineers (IEEE) 1102.11 standards, the IEEE 1102.15 standards, the Bluetooth® standards asdefined by the Bluetooth Special Interest Group (SIG), or the Long Term Evolution (LTE), 3G, 4G or 5G (New Radio (NR)) standards promulgated by the 3rd Generation Partnership Project (3 GPP), among others. The described examples may be implemented in any device, system or network that is capable of transmitting and receiving RF signals according to one or more of the following technologies or techniques: code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), single-carrier FDMA (SC-FDMA), spatial division multiple access (SDMA), rate-splitting multiple access (RSMA), multi-user shared access (MUSA), single-user (SU) multiple-input multiple-output (MIMO) and multi-user (MU)- MIMO. The described examples also may be implemented using other wireless communication protocols or RF signals suitable for use in one or more of a wireless personal area network (WPAN), a wireless local area network (WLAN), a wireless wide area network (WWAN), a wireless metropolitan area network (WMAN), or an internet of things (loT) network.

[0059] Various aspects relate generally to wireless positioning systems. Some aspects more specifically relate to wireless positioning devices configured to subsample measurements based on one of a plurality of subsampling configurations.

[0060] In some examples, a wireless device, such as a user equipment (UE), a base station, or a transmission reception point (TRP) may select a subsampling configuration from a plurality of subsampling configurations. The wireless device may receive a set of positioning signals. The wireless device may measure the received set of positioning signals. The wireless device may calculate a subset of measurements of the measured set of positioning signals based on the selected subsampling configuration. The wireless device may output the calculated subset of measurements to a positioning model. For example, the wireless device may train the positioning model based on the calculated subset of measurements, the wireless device may calculate a set of positioning outputs based on the calculated subset of measurements, or the wireless device may transmit the calculated subset of measurements for the positioning model (e.g., to a location management function (LMF). The positioning model may be, for example, a positioning model trained using artificial intelligence machine learning (AI / ML).

[0061] In some examples, a network entity, such as an LMF may transmit an indicator of a plurality of subsampling configurations. The network entity may receive a positioning report including at least one of a set of measurements based on at least one of the plurality of subsampling configurations or a set of positioning outputs based on the at least one of the plurality of subsampling configurations. Subsampling may include selecting a subset of samples to use, for example by truncating a sample or by selecting samples associated with a subset of paths.

[0062] For positioning models at a network entity (e.g., LMF), a wireless device (e.g., UE, base station) may select and report a subset of samples and / or paths of measurements (e.g., channel impulse response (CIR), power delay profile (PDP), delay profile (DP)). If the subsampling method for training the positioning model is different from the subsampling method for using the positioning model to calculate positioning outputs, the positioning accuracy when using the positioning model to calculate positioning outputs may degrade. In some aspects, a wireless device may be configured by a network entity (e.g., an LMF) for a plurality of subsampling methods to determine subsampling measurements (i.e., path and / or sample measurements) for a positioning model. The wireless device may measure reference signals and determine subsampling measurements based on a selected subsampling method and may report an indicator of the selected subsampling method to the network entity along with the calculated subsampling measurements. The wireless device may be configured for the selected method by the network entity or the wireless device may be configured to select the subsampling method based on different criteria. For example, depending upon the multipath nature of a wireless device, some subsampling configurations may provide richer features than others. For example, in a rich multipath environment (e.g., large number of reflections), considering subsampling based on peaks may enrich the feature space and produce better positioning calculations than a subsampling method based on a strongest power / magnitude. In another example, if a channel has a limited number of peaks (e.g., low multipath order, smaller number of paths), subsampling with a stronger power / magnitude may produce more accurate results. The criteria may include, for example, a delay spread of a measured positioning signal (e.g., CIR, PDP, or DP measurement), a Rician factor (i.e., K-factor) of a measured positioning signal, a peak width, a number of paths, or a path order. The wireless device may select a subsampling configuration based on a measurement satisfying a range (e.g.,subsample based on peaks if the number of paths is greater or equal to a threshold value, subsample based on power / magnitude if the number of paths is less than or equal to a threshold value). A power of a signal may be computed based on the magnitude of a measurement of samples. In other words, the power may be a different scale than the magnitude, allowing both power and magnitude to express the same measurement in different ways.

[0063] In one aspect, the wireless device and network entity may agree on supported subsampling methods and corresponding identifiers (IDs) offline (e.g., without signaling such configurations). During operation, the wireless device and network entity may refer to the subsampling configurations based on the agreed upon subsampling IDs. In one aspect, a supported subsampling method be assigned as part of meta information associated with a positioning model when doing positioning model registration via an ID used to refer to the subsampling method. In one aspect, the subsampling method may be applied based on a beam, a transmission reception point (TRP), and / or a positioning frequency layer(PFL) basis. In one aspect, a network entity may configure both the subsampling method at one or both of a TRP and / or a UE.

[0064] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by configuring a wireless device to select from a plurality of subsampling configurations to measure positioning signals, the described techniques can be used to improve the accuracy and reliability of using positioning models to calculate a set of positioning outputs.

[0065] The detailed description set forth below in connection with the drawings describes various configurations and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

[0066] Several aspects of telecommunication systems are presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks,components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0067] By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. When multiple processors are implemented, the multiple processors may perform the functions individually or in combination. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise, shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.

[0068] Accordingly, in one or more example aspects, implementations, and / or use cases, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, such computer-readable media can include a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the types of computer- readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.

[0069] While aspects, implementations, and / or use cases are described in this application by illustration to some examples, additional or different aspects, implementations and / or use cases may come about in many different arrangements and scenarios. Aspects, implementations, and / or use cases described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, aspects, implementations, and / or use cases may come about via integrated chip implementations and other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, artificial intelligence (Al)-enabled devices, etc.). While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described examples may occur. Aspects, implementations, and / or use cases may range a spectrum from chip-level or modular components to non-modular, non-chip- level implementations and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more techniques herein. In some practical settings, devices incorporating described aspects and features may also include additional components and features for implementation and practice of claimed and described aspect. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes (e.g., hardware components including antenna, RF-chains, power amplifiers, modulators, buffer, processor(s), interleaver, adders / summers, etc.). Techniques described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc. of varying sizes, shapes, and constitution.

[0070] Deployment of communication systems, such as 5GNR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element, or a network equipment, such as a base station (BS), or one or more units (or one or more components) performing base station functionality, may be implemented in an aggregated or disaggregated architecture. For example, a BS (such as a Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), a transmission reception point(TRP), or a cell, etc.) may be implemented as an aggregated base station (also known as a standalone BS or a monolithic BS) or a disaggregated base station.

[0071] An aggregated base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A disaggregated base station may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other RAN nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU and RU can be implemented as virtual units, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0072] Base station operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an integrated access backhaul (IAB) network, an open radio access network (O- RAN (such as the network configuration sponsored by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Disaggregation may include distributing functionality across two or more units at various physical locations, as well as distributing functionality for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station, or disaggregated RAN architecture, can be configured for wired or wireless communication with at least one other unit.

[0073] FIG. 1 is a diagram 100 illustrating an example of a wireless communications system and an access network. The illustrated wireless communications system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that can communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units (such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) 125 via an E2 link, or a Non-Real Time (Non-RT) RIC 115 associated with a Service Management and Orchestration (SMO) Framework 105, or both). A CU 110 may communicate with one or more DUs 130 via respective midhaul links, such as an Fl interface. The DUs 130 may communicate with one ormore RUs 140 via respective fronthaul links. The RUs 140 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 140.

[0074] Each of the units, i.e., the CUs 110, the DUs 130, the RUs 140, as well as the Near- RT RICs 125, the Non-RT RICs 115, and the SMO Framework 105, may include one or more interfaces or be coupled to one or more interfaces configured to receive or to transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or to transmit signals over a wired transmission medium to one or more of the other units. Additionally, the units can include a wireless interface, which may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), configured to receive or to transmit signals, or both, over a wireless transmission medium to one or more of the other units.

[0075] In some aspects, the CU 110 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 110. The CU 110 may be configured to handle user plane functionality (i.e., Central Unit - User Plane (CU-UP)), control plane functionality (i.e., Central Unit - Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 110 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as an El interface when implemented in an O-RAN configuration. The CU 110 can be implemented to communicate with the DU 130, as necessary, for network control and signaling.

[0076] The DU 130 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 140. In some aspects, the DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules forforward error correction (FEC) encoding and decoding, scrambling, modulation, demodulation, or the like) depending, at least in part, on a functional split, such as those defined by 3 GPP. In some aspects, the DU 130 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 130, or with the control functions hosted by the CU 110.

[0077] Lower-layer functionality can be implemented by one or more RUs 140. In some deployments, an RU 140, controlled by a DU 130, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as 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, the RU(s) 140 can be implemented to handle over the air (OTA) communication with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 140 can be controlled by the corresponding DU 130. In some scenarios, this configuration can enable the DU(s) 130 and the CU 110 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0078] The SMO Framework 105 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements that may be managed via an operations and maintenance interface (such as an 01 interface). For virtualized network elements, the SMO Framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 190) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an 02 interface). Such virtualized network elements can include, but are not limited to, CUs 110, DUs 130, RUs 140 and Near-RT RICs 125. In some implementations, the SMO Framework 105 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O- eNB) 111, via an 01 interface. Additionally, in some implementations, the SMO Framework 105 can communicate directly with one or more RUs 140 via an 01interface. The SMO Framework 105 also may include a Non-RT RIC 115 configured to support functionality of the SMO Framework 105.

[0079] The Non-RT RIC 115 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence (Al) / machine learning (ML) (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near- RT RIC 125. The Non-RT RIC 115 may be coupled to or communicate with (such as via an Al interface) the Near-RT RIC 125. The Near-RT RIC 125 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 (such as via an E2 interface) connecting one or more CUs 110, one or more DUs 130, or both, as well as an O-eNB, with the Near-RT RIC 125.

[0080] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 125, the Non-RT RIC 115 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 125 and may be received at the SMO Framework 105 or the Non-RT RIC 115 from non-network data sources or from network functions. In some examples, the Non-RT RIC 115 or the Near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 115 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 105 (such as reconfiguration via 01) or via creation of RAN management policies (such as Al policies).

[0081] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Accordingly, a base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component indicated with dotted lines to signify that each component may or may not be included in the base station 102). The base station 102 provides an access point to the core network 120 for a UE 104. The base station 102 may include macrocells (high power cellular base station) and / or small cells (low power cellular base station). The small cells include femtocells, picocells, and microcells. A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs), which may provide service to a restricted group known as a closed subscriber group (CSG). The communication links between theRUs 140 and the UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to an RU 140 and / or downlink (DL) (also referred to as forward link) transmissions from an RU 140 to a UE 104. The communication links may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links may be through one or more carriers. The base station 102 / UEs 104 may use spectrum up to X MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Ex MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell).

[0082] Certain UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL / UL wireless wide area network (WWAN) spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication may be through a variety of wireless D2D communications systems, such as for example, Bluetooth™ (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG)), Wi-Fi™ (Wi-Fi is a trademark of the Wi-Fi Alliance) based on the Institute of Electrical and Electronics Engineers (IEEE) 1102.11 standard, LTE, or NR.

[0083] The wireless communications system may further include a Wi-Fi AP 150 in communication with UEs 104 (also referred to as Wi-Fi stations (STAs)) via communication link 154, e.g., in a 5 GHz unlicensed frequency spectrum or the like. When communicating in an unlicensed frequency spectrum, the UEs 104 / AP 150 may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.

[0084] The electromagnetic spectrum is often subdivided, based on frequency / wavelength, into various classes, bands, channels, etc. In 5GNR, two initial operating bands havebeen identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

[0085] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend features of FR1 and / or FR2 into midband frequencies. In addition, higher frequency bands are currently being explored to extend 5GNR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6 GHz - 71 GHz), FR4 (71 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0086] With the above aspects in mind, unless specifically stated otherwise, the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0087] The base station 102 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate beamforming. The base station 102 may transmit a beamformed signal 182 to the UE 104 in one or more transmit directions. The UE 104 may receive the beamformed signal from the base station 102 in one or more receive directions. The UE 104 may also transmit a beamformed signal 184 to the base station 102 in one or more transmit directions. The base station 102 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 102 / UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 102 / UE 104. The transmit and receive directions for the base station 102 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.

[0088] The base station 102 may include and / or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a TRP, network node, network entity, network equipment, or some other suitable terminology. The base station 102 can be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, an aggregated (monolithic) base station with a baseband unit (BBU) (including a CU and a DU) and an RU, or as a disaggregated base station including one or more of a CU, a DU, and / or an RU. The set of base stations, which may include disaggregated base stations and / or aggregated base stations, may be referred to as next generation (NG) RAN (NG-RAN).

[0089] The core network 120 may include an Access and Mobility Management Function (AMF) 161, a Session Management Function (SMF) 162, a User Plane Function (UPF) 163, a Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. The AMF 161 is the control node that processes the signaling between the UEs 104 and the core network 120. The AMF 161 supports registration management, connection management, mobility management, and other functions. The SMF 162 supports session management and other functions. The UPF 163 supports packet routing, packet forwarding, and other functions. The UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identification handling, access authorization, and subscription management. The one or more location servers 168 are illustrated as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, the LMF 166, a position determination entity (PDE), a serving mobile location center (SMLC), a mobile positioning center (MPC), or the like. The GMLC 165 and the LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) for accessing UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to compute the position of the UE104. The NG-RAN may utilize one or more positioning methods in order to determine the position of the UE 104. Positioning the UE 104 may involve signal measurements, a position estimate, and an optional velocity computation based on the measurements. The signal measurements may be made by the UE 104 and / or the base station 102 serving the UE 104. The signals measured may be based on one or more of a satellite positioning system (SPS) 170 (e.g., one or more of a Global Navigation Satellite System (GNSS), global position system (GPS), non-terrestrial network (NTN), or other satellite position / location system), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., barometric pressure sensor, motion sensor), NR enhanced cell ID (NRE-CID) methods, NR signals (e.g., multi -round trip time (Multi -RTT), DL angle- of-departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle-of-arrival (UL-AoA) positioning), and / or other systems / signals / sensors.

[0090] Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similar functioning device. Some of the UEs 104 may be referred to as loT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc.). The UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices such as in a device constellation arrangement. One or more of these devices may collectively access the network and / or individually access the network.

[0091] Referring again to FIG. 1, in certain aspects, the UE 104 and / or a base station 102 may have a subsampling component 198 that may be configured to select a subsampling configuration from a plurality of subsampling configurations. Thesubsampling component 198 may be configured to receive a set of positioning signals. The subsampling component 198 may be configured to measure the received set of positioning signals. The subsampling component 198 may be configured to calculate a subset of measurements of the measured set of positioning signals based on the selected subsampling configuration. The subsampling component 198 may be configured to output the calculated subset of measurements to a positioning model, for example by training the positioning model based on the calculated subset of measurements, by calculating a set of positioning outputs based on the calculated subset of measurements, or by transmitting the calculated subset of measurements for the positioning model (e.g., to the LMF 166). In certain aspects, the base station 102, the core network 120, the one or more location servers 168, or the LMF 166 may have a subsampling configuration component 199 that may be configured to transmit an indicator of a plurality of subsampling configurations. The subsampling configuration component 199 may be configured to receive a positioning report including at least one of a set of measurements based on at least one of the plurality of subsampling configurations or a set of positioning outputs based on the at least one of the plurality of subsampling configurations.

[0092] FIG. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. FIG. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplexed (FDD) in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for either DL or UL, or may be time division duplexed (TDD) in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by FIGs. 2A, 2C, the 5G NR frame structure is assumed to be TDD, with subframe 4 being configured with slot format 28 (with mostly DL), where D is DL, U is UL, and F is flexible for use between DL / UL, and subframe 3 being configured with slot format 1 (with all UL). While subframes 3, 4 are shown with slot formats 1, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI), or semi- statically / statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI). Note that the description infra applies also to a 5G NR frame structure that is TDD.

[0093] FIGs. 2A-2D illustrate a frame structure, and the aspects of the present disclosure may be applicable to other wireless communication technologies, which may have a different frame structure and / or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each slot may include 14 symbols, and for extended CP, each slot may include 12 symbols. The symbols on DL may be CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (for power limited scenarios; limited to a single stream transmission). The number of slots within a subframe is based on the CP and the numerology. The numerology defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration may scale with 1 / SCS.Table 1: Numerology, SCS, and CP

[0094] For normal CP (14 symbols / slot), different numerologies p 0 to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. For extended CP, the numerology 2 allowsfor 4 slots per subframe. Accordingly, for normal CP and numerology p, there are 14 symbols / slot and 2^ slots / subframe. The subcarrier spacing may be equal to 2 * 15 kHz, where g is the numerology 0 to 4. As such, the numerology p=0 has a subcarrier spacing of 15 kHz and the numerology p=4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIGs. 2A-2D provide an example of normal CP with 14 symbols per slot and numerology p=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 ps. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see FIG. 2B) that are frequency division multiplexed. Each BWP may have a particular numerology and CP (normal or extended).

[0095] A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs)) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0096] As illustrated in FIG. 2A, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0097] FIG. 2B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP may be referred to as a control resource set (CORESET). A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at greater and / or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe / symbol timing and aphysical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as SS block (SSB)). The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and paging messages.

[0098] As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE may transmit sounding reference signals (SRS). The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequencydependent scheduling on the UL.

[0099] FIG. 2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACK and / or negative ACK (NACK)). The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0100] FIG. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In the DL, Internet protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0101] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding / decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domain, and then combinedtogether using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier with a respective spatial stream for transmission.

[0102] At the UE 350, each receiver 354Rx receives a signal through its respective antenna 352. Each receiver 354Rx recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions may be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller / processor 359, which implements layer 3 and layer 2 functionality.

[0103] The controller / processor 359 can be associated with at least one memory 360 that stores program codes and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IPpackets. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0104] Similar to the functionality described in connection with the DL transmission by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0105] Channel estimates derived by a channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antenna 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a respective spatial stream for transmission.

[0106] The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318Rx receives a signal through its respective antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to a RX processor 370.

[0107] The controller / processor 375 can be associated with at least one memory 376 that stores program codes and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0108] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform aspects in connection with the subsampling component 198 of FIG. 1.

[0109] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform aspects in connection with the subsampling component 198 of FIG. 1.

[0110] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform aspects in connection with the subsampling configuration component 199 of FIG. 1.[OHl] FIG. 4 is a diagram 400 illustrating an example of a positioning based on positioning signal measurements. A positioning signal may be any reference signal which may be measured to calculate a position attribute or a location attribute of a wireless device, for example a positioning reference signal (PRS), a sounding reference signal (SRS), a channel state information (CSI) reference signal (CSI-RS), or a synchronization and signal block (SSB). The wireless device 402 may be a base station, such as a TRP, or a UE with a known position / location, such as a positioning reference unit (PRU) or a UE with a high-accuracy sensor that may identify the location of the UE, for example a GNSS sensor or a GPS sensor. The wireless device 406 may be a base station or a UE with a known position / location. The wireless device 404 may be a UE or a TRP configured to perform positioning to gather data, for example to gather data to train an artificial intelligence machine learning (AI / ML or AIML) model, test positioning signal strength or test positioning noise attributes in an area. The wireless device 404 may transmit UL-SRS 412 at time TSRS TX and receive DL positioning reference signals (PRS) (DL-PRS) 410 at time TPRS RX. The wireless device 406 may receive the UL-SRS 412 at time TSRS RX and transmit the DL-PRS 410 at time TPRS TX. The wireless device 404 may receive the DL-PRS 410 before transmitting the UL-SRS 412, or may transmit the UL-SRS 412 before receiving the DL-PRS 410. In both cases, a positioning server (e.g., location server(s)168, LMF 166) or the wireless device 404 may determine the RTT 414 based on ||TSRS_RX - TPRS_TX| - |TSRS_TX - TPRS R ||. Accordingly, multi-RTT positioning may make use of the UE Rx-Tx time difference measurements (i.e., |TSRS_TX - TPRS _RX|) and DL-PRS reference signal received power (RSRP) (DL-PRS-RSRP) of downlink signals received from multiple wireless devices 402, 406 and measured by the wireless device 404, and the measuredTRP Rx-Tx time difference measurements (i.e., |TSRS_RX - TPRS _TX|) and UL-SRS- RSRP at multiple wireless devices 402, 406 of uplink signals transmitted from wireless device 404. The wireless device 404 may measure the UE Rx-Tx time difference measurements (and optionally DL-PRS-RSRP of the received signals) using assistance data received from the positioning server, and the wireless devices 402, 406 may measure the gNB Rx-Tx time difference measurements (and optionally UL-SRS-RSRP of the received signals) using assistance data received from the positioning server. The measurements may be used at the positioning server or the wireless device 404 to determine the RTT. The RTT may be used to estimate the location of the wireless device 404. Other methods are possible for determining the RTT, such as for example using DL-TDOA and / or UL-TDOA measurements.

[0112] DL-AoD positioning may make use of the measured DL-PRS-RSRP of downlink signals received from multiple wireless devices 402, 406 at the wireless device 404. The wireless device 404 may measure the DL-PRS-RSRP of the received signals using assistance data received from the positioning server, and the resulting measurements may be used along with the azimuth angle of departure (A-AoD), the zenith angle of departure (Z-AoD), and / or other configuration information to locate the wireless device 404 in relation to the neighboring wireless devices 402, 406.

[0113] DL-TDOA positioning may make use of the DL reference signal time difference (RSTD) (and optionally DL-PRS-RSRP) of downlink signals received from multiple wireless devices 402, 406 at the wireless device 404. The wireless device 404 may measure the DL RSTD (and optionally DL-PRS-RSRP) of the received signals using assistance data received from the positioning server, and the resulting measurements may be used along with other configuration information to locate a position / location the wireless device 404 in relation to the neighboring wireless devices 402, 406.

[0114] UL-TDOA positioning may make use of the UL relative time of arrival (RTOA) (and optionally UL-SRS-RSRP) at multiple wireless devices 402, 406 of uplink signals transmitted from wireless device 404. The wireless devices 402, 406 may measure the UL-RTOA (and optionally UL-SRS-RSRP) of the received signals using assistance data received from the positioning server, and the resulting measurements may be used along with other configuration information to estimate the location of the wireless device 404.

[0115] UL-AoA positioning may make use of the measured azimuth angle of arrival (A-AoA) and zenith angle of arrival (Z-AoA) at multiple wireless devices 402, 406 of uplink signals transmitted from the wireless device 404. The wireless devices 402, 406 may measure the A-AoA and the Z-AoA of the received signals using assistance data received from the positioning server, and the resulting measurements may be used along with other configuration information to estimate the location of the wireless device 404.

[0116] Additional positioning methods may be used for estimating the location of the wireless device 404, such as for example, UE-side UL-AoD and / or DL-AoA. Note that data / measurements from various technologies may be combined in various ways to increase accuracy, to determine and / or to enhance certainty, to supplement / complement measurements, and / or to substitute / provide for missing information.

[0117] FIG. 5 is a diagram 500 illustrating a network entity 508 that may be configured to coordinate a wireless device 502 and a wireless device 506 to perform positioning with a wireless device 504. The location of the wireless device 502 and the wireless device 506 may be known to at least one of the devices, such as the wireless device 502, the wireless device 504, the wireless device 506, the network entity 508, and / or the server 520. The wireless device 502 may be a base station, a gNB, or a TRP. The wireless device 506 may be a base station, a gNB, or a TRP. The wireless device 504 may be a UE. In some aspects, the UE may be a PRU. A PRU may be a UE with a known location. For example, the PRU may be affixed in a known location or may be placed in a known location for a period of time, or the PRU may have a set of sensors (e.g., high-accuracy GNSS sensor) that may be used to accurately calculate the location of the PRU. In some aspects, the wireless device 504 may be a PRU configured to train a positioning model based on a set of inputs and a set of labels. In some aspects, the wireless device 504 may be a UE configured to use a positioning model to calculate a set of outputs based on a set of inputs, for example measurements of positioning signals. The network entity 508 may be connected to the wireless device 502 and the wireless device 506 via a physical link, for example a backhaul link or a midhaul link, or via a wireless link, such as an air interface (a UE-UTRAN (Uu)) link. The network entity 508 may be part of a core network, such as an LMF or a set of location servers. The network entity 508 may configure positioning occasionsbetween the wireless device 502, the wireless device 504, and the wireless device 506. The server 520 may be an over-the-top (OTT) server or some other server functionally connected to a network that communicates with the network entity 508, the wireless device 502 and / or the wireless device 506, and / or with the wireless device 504 via a wireless device, such as the wireless device 502 and / or the wireless device 506. The server 520 may have storage for storing positioning models, for example AI / ML positioning models, trained using sets of positioning signals received by a wireless device, such as the wireless device 502, the wireless device 504, and / or the wireless device 506.

[0118] To perform positioning, the network entity 508 may configure one or more of the wireless devices to transmit positioning signals at one another. For example, the wireless device 504 may transmit the set of positioning signals 512 at the wireless device 502. The set of positioning signals 512 may be a set of SRSs, SSBs, or CSI- RSs. The wireless device 502 may measure the set of positioning signals 512. The wireless device 502 may transmit the set of positioning signals 516 at the wireless device 504. The set of positioning signals 516 may be a set of PRSs, SSBs, or CSI- RSs. The wireless device 504 may measure the set of positioning signals 516. The wireless device 504 may transmit a set of positioning signals 514 at the wireless device 506. The set of positioning signals 514 may be a set of SRSs, SSBs, or CSI- RSs. The wireless device 506 may measure the set of positioning signals 514. The wireless device 506 may transmit a set of positioning signals 518 at the wireless device 504. The set of positioning signals 518 may be a set of PRSs, SSBs, or CSI- RSs. The wireless device 504 may measure the set of positioning signals 518. One or more of the wireless devices may measure the received positioning signals to calculate a positioning measurement that may be used to calculate a position / location of the wireless device 504, or may be used to calculate a position / location of the wireless device 504. For example, if the location of the wireless device 502 and the location of the wireless device 506 are known, the location of the wireless device 504 may be calculated based on a RTT between the wireless device 502 and the wireless device 504, and a RTT between the wireless device 504 and the wireless device 506. In another example, the wireless device 504 may calculate an angle of arrival (AoA) or an angle of departure (AoD) of the set of positioning signals 516, and may calculate an AoA or an AoD of the set of positioning signals 518. The calculated AoAs and / orAoDs may be used to calculate a position of the wireless device 504 if the location of the wireless device 502 and the location of the wireless device 506 are also known. Other measurements, such as RTOA, line-of-sight (LOS) identification (identifying whether there is a direct line-of-sight path between wireless devices), or multi-cell round trip time (multi-RTT) calculations may be performed to calculate the position of the wireless device 504, or to calculate a measurement that may be used to calculate the position of the wireless device 504.

[0119] In some aspects, a positioning model may be used to calculate one or more positioning metrics based on the measurements. For example, based on the measurements of the set of positioning signals 512 and / or the set of positioning signals 514 transmitted by the wireless device 504, a position / location of the wireless device 504 may be calculated or estimated, or an intermediate measurement that may be used to calculate the position / location of the wireless device 504 may be calculated or estimated. Such a positioning metric may also be referred to as a positioning output. A positioning model may be trained using artificial intelligence (Al) / machine learning (ML) (AI / ML or AIML), based on a set of inputs (e.g., measurements of positioning signals, assistance information associated with the positioning signals) and a set of labels. A positioning signal may include any reference signal transmitted from a wireless device, such as a PRS, a SRS, an SSB, or a CSI-RS. An RS transmitted from a UE, such as a PRU, may be referred to as an uplink positioning signal, or an UL positioning signal. An RS transmitted from a base station, or TRP, may be referred to as a downlink positioning signal, or a DL positioning signal. A measurement may be a delay profile (DP), a power delay profile (PDP), a channel impulse response (CIR), a channel frequency response (CFR), or other measurement used for performing positioning on a target wireless device. A label may be a calculated, derived, or given (i.e., known) expected result associated with a set of inputs, such as a position / location of a wireless device 504 or an intermediate measurement (e.g., a timing measurement, an angle measurement, a LOS identification) that may be used to calculate the position / location of the wireless device 504. A set of inputs and a set of labels may be used for generating and / or training a positioning model using AI / ML.

[0120] When training a positioning model, measurements of positioning signals as inputs, clean or noisy labels (clean labels may have a quality metric greater or equal to a threshold, noisy labels may have a quality metric less than or equal to the threshold)as expected outputs, and training data assistance information as inputs or expected outputs. The positioning model may operate on any wireless device based on a set of inputs. For example, the wireless device 502 may have a positioning model configured to accept a set of positioning measurements and generate an estimate of a position / location of the wireless device 504. In another example, the wireless device 502 may have a positioning model configured to accept a set of positioning measurements and generate an intermediate measurement (e.g., a timing measurement, an angle measurement, a LOS identification) that may be used (by the wireless device 502, or another entity, such as the network entity 508, the wireless device 504, or the wireless device 506) to calculate the position / location of the wireless device 504. In another example, the network entity 508 may have a positioning model configured to accept a set of positioning measurements and generate an estimate of a position / location of the wireless device 504, or generate an intermediate measurement that may be used to calculate the position / location of the wireless device 504. In another example, the wireless device 504 may have a positioning model configured to accept a set of positioning measurements and generate an estimate of a position / location of the wireless device 504, or generate an intermediate measurement that may be used to calculate the position / location of the wireless device 504. In some aspects, the positioning measurements may be aggregated by the entity with the positioning model, for example the network entity 508 may aggregate measurements of the set of positioning signals 512 from the wireless device 502, measurements of the set of positioning signals 514 the wireless device 506 to use as inputs to a positioning model, measurements of the set of positioning signals 516 from the wireless device 504, and / or measurements of the set of positioning signals 518 from the wireless device 504.

[0121] A positioning model may be trained on a wireless device that performs positioning, such as the wireless device 502, the wireless device 504, the wireless device 506, the network entity 508, and / or the server 520. The inputs to the positioning model may include measurements of positioning signals, such as measurements of SRS, PRS, SSB, and / or CSI-RS. The inputs to the measurements may include assistance information associated with the measured positioning signals, such as BWP of a positioning signal resource, number of TRPs, beam information, positioning signal configuration). The labels / outputs for the positioning model may include a location,or an intermediate measurement. In one aspect, the server 520 may be an OTT server configured to train and store positioning models. In another aspect, the network entity 508 may be configured to train and store positioning models. In other words, the server 520 or the network entity 508 may be a training entity configured to train positioning models based on input measurements taken by a wireless device, such as the wireless device 502, the wireless device 504, and / or the wireless device 506, and based on labels either known (e.g., stored on memory) or calculated by at least one of the wireless device 502, the wireless device 504, the wireless device 506, and / or the network entity 508. A positioning model may be configured to calculate a set of outputs. The set of outputs may include, for example, position of a wireless device, a reference signal time difference (RSTD), a line of sight (LOS) indicator (e.g., whether there exists a direct line-of-sight path between wireless devices, the likelihood of whether there exists a direct line-of-sight path between wireless devices), a multipath timing indicator (e.g., a time of flight per path, a time of arrival per path with respect to a timing mark), a multipath power indicator (e.g., strength of a signal per path), a multipath phase indicator (e.g., phase of a signal per path), a reference signal received power (RSRP), and / or an angle of departure (AoD).

[0122] In some aspects, a positioning model may be configured to use measurements of positioning signals transmitted from a wireless device to calculate a position of the wireless device 504, or to calculate an intermediate measurement that may be used to calculate the position of the wireless device 504. The positioning model may be trained via a training entity, and may be used at the wireless device 502, at the wireless device 504, at the wireless device 506, or at the network entity 508. For example, a positioning model at the wireless device 504 may be configured to calculate the location of the wireless device 504 based on measurements of the set of positioning signals 516 and / or the set of positioning signals 518. In another example, the wireless device 502 may transmit a set of intermediate measurements to the network entity 508 so that the network entity 508 may calculate the location of the wireless device 504 based on the set of intermediate measurements. In another example, the wireless device 504 may transmit measurements of the set of positioning signals 516 and / or the set of positioning signals 518 to the network entity 508. The positioning model may be at the network entity 508. The positioning model at the network entity 508 may calculate the location of the wireless device 504 based on the transmittedmeasurements of the set of positioning signals 516 and / or the set of positioning signals 518 from the wireless device 504, the transmitted measurements of the set of positioning signals 512 from the wireless device 502, and / or the transmitted measurements of the set of positioning signals 514 from the wireless device 506. In other words, any of the wireless device 502, the wireless device 504, and / or the wireless device 506 may assist the network entity 508 in performing positioning using a trained positioning model.

[0123] In some aspects, a positioning model may be site-specific. For example, a first positioning model may be trained in a location, or a set of locations, associated with a first site having a first set of borders, and a second positioning model may be trained in a location, or a set of locations, associated with a second site having a second set of borders. A wireless device may be configured to use one of a plurality of sitespecific positioning models. For example, the wireless device may select a sitespecific positioning model based on its location, or may select a site-specific positioning model based on an indicator, for example a signal transmitted from the network entity 508 that indicates that a particular site-specific positioning model from a plurality of site-specific positioning models be selected.

[0124] Measurements of positioning signals may be performed by measuring channels between a target device (e.g., the wireless device 504) and a set of network nodes (e.g., the wireless device 502 and the wireless device 506). The wireless device 504 may transmit a positioning signal, such as an SRS, an SSB, or a CSI-RS. The wireless device 502 and / or the wireless device 506 may measure the positioning signal for data collection purposes to train a positioning model. The wireless device 504 and / or the wireless device 506 may transmit a positioning signal, such as a PRS, an SSB, or a CSI-RS. The wireless device 504 may measure the positioning signal for data collection purposes to train the positioning model. The wireless device 502, the wireless device 504, and / or the wireless device 506 may measure a positioning signal resource in a plurality of ways, for example the measurement may be a channel impulse response (CIR), a channel frequency response (CFR), a power delay profile (PDP), a delay profile (DP), a set of reflection paths, a reception-transmission (Rx- Tx) time difference, a received signal strength indicator (RS SI), a reference signal received power (RSRP), a reference signal received power per path (RSRPP), a reference signal received quality (RSRQ), a time of arrival (To A), a time of departure(ToD), a reference signal time difference (RSTD), an angle of arrival (AoA), and / or an angle of departure (AoD).

[0125] While the diagram 500 illustrates two positioning neighbor wireless devices, wireless device 502 and wireless device 506, configured to perform positioning with one positioning target wireless device, wireless device 504, to calculate a position / location of the wireless device 504, any number of positioning neighbor wireless devices may be configured to perform positioning with any number of positioning target wireless devices. For example, four positioning neighbor wireless devices may be configured to calculate the position / location of two positioning target wireless devices, three positioning neighbor wireless devices may be configured to calculate the position / location of one positioning target wireless device, or two positioning neighbor wireless devices may be configured to calculate the position / location of one positioning target wireless device.

[0126] A measurement of a positioning signal (PRS, SRS, SSB) may include a channel frequency response (CFR) measurement, a channel impulse response (CIR) measurement, a power delay profile (PDP) measurement, or a delay profile (DP) measurement. A wireless device may measure a CFR by applying channel estimation in a frequency domain based on a positioning signal sequence (e.g., a PRS sequence, an SRS sequence) mapped to a set of OFDM signals. The wireless device may measure a CIR based on a CFR, for example by applying an inverse fast Fourier transform (IFFT) to the CFR (i.e., CIR = IFFT (CFR)). The wireless device may calculate a CIR as the largest measurement size, where the CIR includes a list of measurements where each measurement contains the information of a delay, power, and phase of a positioning signal. The wireless device may subsample a CIR by applying truncation to such a CIR. The CIR may also correspond with a set of time, power / magnitude, and / or phase information that are derived from the output of an IFFT of the CFR. The wireless device may measure a PDP be calculating the absolute value of a CIR (i.e., abs (CIR)) at a particular measurement point. The wireless device may calculate a PDP by correlating a plurality of time and power information derived from the CIR. The wireless device may calculate a PDP as a smaller measurement size than the CIR, where the PDP includes a list of measurements where each measurement contains the information of a delay and power of a positioning signal. The wireless device may subsample a PDP by applying truncation to the PDP. Thewireless device may calculate a DP by correlating timing information of CIR or PDP measurements with the significant power information or peak information. The wireless device may calculate a DP by correlating a plurality of timing information derived from a CIR or PDP. In some aspects, the wireless device may calculate a DP by degenerating the PDP (e.g., the timing representation of the PDP). The wireless device may calculate a DP as a smallest measurement size, where the DP includes a list of measurements where each measurement contains the information of a delay. The wireless device may subsample a DP by applying truncation to the DP.

[0127] In some aspects, a positioning model may be trained using subsampled measurements, for example truncated measurements, specific values of samples (e.g., local maximum values, local minimum values), or samples associated with specified paths (e.g., first received path, direct LOS path). A wireless device that measures positioning signals (e.g., a CIR, PDP, or DP measurement of a PRS, SRS, or SSB) may use a predefined methodology to subsample measurements to use for a positioning model. The subsampled measurements may be used to train a positioning model along with a set of labels, or may be used to calculate positioning outputs using a trained positioning model. In some aspects, where the positioning model is not on a wireless device that receives and measures positioning signals (e.g., at the network entity 508, at the server 520), wireless resources may be conserved by transmitting subsampled measurements to the entity with the positioning model. The wireless device receiving positioning signals may subsample a measurement (e.g., CIR / PDP / DP) of a positioning signal (e.g., PRS, SRS, SSB) using a subsampling configuration to select a subset of the measurements to report. A wireless device, for example the wireless device 502, the wireless device 504, or the wireless device 506, may report subsampled measurements of a positioning signal using a predefined methodology, for example by selecting a subset of specific measurements, measurements associated with a subset of samples, or measurements associated with a subset of paths, for reporting to the device with the positioning model (e.g., the network entity 508, the server 520). The network entity 508 may exchange control signals with such a wireless device to ensure that subsampling is aligned between the wireless device and the device with the positioning model.

[0128] In some aspects, the wireless device may keep a plurality of subsampling configurations in device memory at a time if the subsampling configurations arefrequently activated (e.g., at least once every ten minutes), allowing the wireless device to dynamically switch between subsampling configurations kept in device memory. The wireless device may be configured to activate a plurality of positioning models activated (e.g., loaded in memory and ready to use to calculate a positioning output based on input measurements), where each of the plurality of positioning models corresponds with a different subsampling configuration. In some aspects, the plurality of positioning models may consider different periodicity (e.g., alternating) of their measurement occasions to provide different positioning accuracy. In such aspects, the positioning models may appear to be running simultaneously, even if they may be utilized in an alternating fashion. For example, a positioning model with high complexity (e.g., larger processing time) may be configured to accept a first subsampling configuration running on a longer repetition of measurement occasion (e.g., every 4 measurement occasions) when compared to a positioning model with a lower complexity (e.g., lower processing time) running on a shorter repetition of measurement occasion (e.g., 3 measurement occasions in a row, then skipping one measurement occasion). The positioning model with higher complexity be more accurate than the positioning model with lower complexity, and may bolster the calculations of the positioning model with lower complexity.

[0129] In some aspects, the network entity 508 may be configured to activate a subsampling method at a wireless device (e.g., the wireless device 502, the wireless device 504, or the wireless device 506) via a command issued from the network entity 508 to the wireless device. The wireless device may calculate a subsample of a set of measurements based on the activated method and report the subsampled measurements to the network entity 508. In some aspects, a wireless device may be configured to autonomously select a configured method. The network entity 508 may provide a variety of configured methods to the wireless device, or a set of positioning models associated with the configured methods (e.g., a set of positioning model IDs that have been trained using the configured methods). The wireless device may calculate a subsample of a set of measurements based on the activated method and report the subsampled measurements to the network entity 508 along with an indicator of the autonomously selected configured method.

[0130] As used herein, a subsample may include a selected path of a set of paths received by the wireless device or a selected sample of a set of samples received by the wirelessdevice. A sample may refer to a signal processing entity that is correlated with a set of timing information, power / magnitude information, and phase information. A path may refer to a geometrical description of a signal trajectory from a transmitting device to a receiving device. A path may also be correlated with a set of timing information, power / magnitude information, and phase information. A subsample may correspond with a path. A subsample may be used to describe a path. A wireless device may process a set of samples to obtain timing, power / magnitude, and phase information associated with a path. For example, a wireless device may apply interpolation between samples to obtain timing, power / magnitude, and phase information associated with a path. In another example, a wireless device may apply a super resolution method (e.g., multiple signal classification (MUSIC) or matrix pencil) to obtain timing, power / magnitude, and phase information associated with a path.

[0131] FIG. 6A is a diagram 600 illustrating an example of a positioning model 602. The positioning model 602 may be trained using direct positioning labels. For example, the positioning model 602 may be trained using a set of measurement inputs 604 and a set of label inputs 603. The set of measurement inputs 604 may include, for example, a set of measurements of SRS positioning signals, a set of measurements of PRS positioning signals, and / or a set of measurements of SSB positioning signals. The measurements may include a CFR, a CIR, a PDP, and / or a DP. The set of label inputs 603 may include, for example, a location of a wireless device, for example a PRU / UE with a known location, or a sensor that can accurately calculate the location of the wireless device (e.g., a GPS sensor, a camera). The positioning model 602 may be trained using AI / ML techniques to calculate the set of label inputs 603 based on the set of measurement inputs 604.

[0132] Once the positioning model 602 is trained, the positioning model 602 may be used to calculate a set of outputs 606 based on the set of measurement inputs 604. The set of outputs 606 may include an estimate of the location of a wireless device that received and measured a set of positioning signals, or that transmitted a set of positioning signals for measuring at another wireless device. The positioning model 602 may be referred to as a direct positioning model that directly calculates a location of a wireless device. In some aspects, the positioning model 602 may be trained using AI / ML techniques, in which case the positioning model 602 may be referred to as a direct AI / ML positioning model.

[0133] FIG. 6B is a diagram 650 illustrating an example of a positioning model 652. The positioning model 652 may be trained using intermediate measurement labels. Intermediate measurements may be measurements that may be used to calculate a location of a wireless device. For example, the positioning model 652 may be trained using a set of inputs 654 and a set of labels 653. The set of inputs 654 may include, for example, a set of measurements of SRS positioning signals, a set of measurements of PRS positioning signals, and / or a set of measurements of SSB positioning signals. The measurements may include a CFR, a CIR, a PDP, and / or a DP. The set of labels 653 may include, for example, a set of timing measurements (e.g., ToA, ToD), a set of angle measurements (e.g., AoA, AoD), or a line-of-sight (LOS) identification (e.g., a probability that there exists a direct line of sight between a wireless device that transmits a positioning signal and a wireless device that receives a positioning signal). The set of labels 653 may be obtained by known environmental conditions, for example a training entity may know that there exists a barrier that blocks a direct LOS between two wireless devices, or a training entity may know the AoD of a positioning signal that is transmitted from a wireless device. The wireless device may be a PRU / UE in a known environment where intermediate measurements are known. The positioning model 652 may be trained using AI / ML techniques to calculate the set of labels 653 based on the set of inputs 654.

[0134] Once the positioning model 652 is trained, the positioning model 652 may be used to calculate a set of outputs 656 based on the set of inputs 654.

Sets should be interpreted as a set of elements where the elements number one or more. Accordingly, for a set of X, X would include one or more elements. When at least one processor is configured to perform a set of functions, the at least one processor, individually or in any combination, is configured to perform the set of functions. Accordingly, eachprocessor of the at least one processor may be configured to perform a particular subset of the set of functions, where the subset is the full set, a proper subset of the set, or an empty subset of the set. A processor may be referred to as processor circuitry. A memory / memory module may be referred to as memory circuitry. If a first apparatus receives data from or transmits data to a second apparatus, the data may be received / transmitted directly between the first and second apparatuses, or indirectly between the first and second apparatuses through a set of apparatuses. A device configured to “output” data or “provide” data, such as a transmission, signal, or message, may transmit the data, for example with a transceiver, may send the data to a component of the device that transmits the data, or may send the data to a component of the device. A device configured to “obtain” data, such as a transmission, signal, or message, may receive, for example with a transceiver, may obtain the data from a component of the device that receives the data, or may obtain the data from a component of the device. Information stored in a memory includes instructions and / or data.
