Description

Technical Field

[0001] The present disclosure relates generally to communication systems, and more particularly, to a mobile device with a low power (LP) wake-up receiver (LP-WUR). Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcast. 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.

[0003] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, or even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continued mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the 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). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0004] A simplified summary of one or more aspects is presented below to provide a basic understanding of these aspects. This summary is not an extensive review of all contemplated aspects. This summary neither identifies the key or important elements of all aspects, nor describes the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to a more detailed description presented later.

The apparatus may receive combined assistance data for a first set of low power (LP) positioning reference signals (LP-PRS), a second set of LP-PRS, a first set of associated downlink (DL) positioning reference signals (DL-PRS), and a second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of associated DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. The apparatus may receive the first set of LP-PRS and the second set of LP-PRS via a first receiver. The apparatus may receive the first set of associated DL-PRS and the second set of associated DL-PRS via a second receiver. The second receiver may be different from the first receiver. The apparatus may measure the first set of LP-PRS and the second set of LP-PRS based on the combined assistance data. The apparatus may update a priority for measuring the first set of associated DL-PRSs or the second set of associated DL-PRSs based on the measured first set of LP-PRSs and the measured second set of LP-PRSs.

[0006] In one aspect of the present disclosure, a method, a computer-readable medium, and an apparatus at a first network node are provided. The apparatus may send combined assistance data for a first set of LP-PRS, a second set of LP-PRS, a first set of associated DL-PRS, and a second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of associated DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. The apparatus may receive an indication of a priority for measuring the first set of associated DL-PRS or the second set of associated DL-PRS based on the first set of LP-PRS and the second set of LP-PRS.

[0007] In one aspect of the present disclosure, a method, a computer readable medium, and an apparatus at a second network node are provided. The apparatus may send a first set of LP-PRS and a second set of LP-PRS to a first receiver of a UE. The apparatus may send a first set of associated DL-PRS and a second set of associated DL-PRS to a second receiver. The second receiver may be different from the first receiver.

[0027] The specific embodiments described below in conjunction with the accompanying drawings are descriptions of various configurations and do not represent the only configurations in which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the specific embodiments include specific details. However, these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring such concepts.

[0028] 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 on the specific application and the design constraints imposed on the overall system.

[0029] As an example, an element or any part of an element or any combination of elements can be implemented as a "processing system", which includes one or more processors. 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 chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware configured to perform various functions described throughout the present disclosure. One or more processors in a processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.

[0030] Thus, in one or more example aspects, specific implementations and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available media that can be accessed by a computer. For example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of these 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.

[0031] Although various aspects, specific implementations and / or use cases are described in this application by the illustration of some examples, additional or different aspects, specific implementations and / or use cases may be generated in many different arrangements and scenarios. The various aspects, specific implementations and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes and packaging arrangements. For example, various aspects, specific implementations and / or use cases can be generated via integrated chip specific implementations and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, artificial intelligence (AI) enabled devices, etc.). Although some examples may or may not be specifically for use cases or applications, the described examples may have a wide range of applicability. Various aspects, specific implementations and / or use cases may be in the range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregated, distributed or original equipment manufacturer (OEM) devices or systems in conjunction with one or more technologies herein. In some actual settings, the equipment combined with the various aspects and features described may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.) The various techniques described herein can be practiced in a wide variety of devices of various sizes, shapes, and configurations, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc.

[0032] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. 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 network equipment (such as a base station (BS)) or one or more units (or one or more components) performing base station functions can be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as an aggregated base station (also referred to as an independent BS or a monolithic BS) or a decomposed base station.

[0033] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between 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 in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0034] Base station operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configurations such as those initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Various units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0035] Figure 1 1 is a diagram 100 illustrating an example of a wireless communication system and an access network. The illustrated wireless communication system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that may 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. The CU 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RU 140 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0036] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interfaces of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive signals or send signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive and / or send signals to one or more of the other units via a wireless transmission medium.

[0037] In some aspects, CU 110 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 110. CU 110 may be configured to handle user plane functions (i.e., central unit-user plane (CU-UP)), control plane functions (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 110 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 110 may be implemented to communicate with DU 130 for network control and signaling.

[0038] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 140. In some aspects, 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 for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to a functional split such as those defined by 3GPP. In some aspects, DU 130 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0039] The lower layer functions may be implemented by one or more RUs 140. In some deployments, the RU 140 controlled by the 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, etc.), or both, based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration may enable the implementation of the DU 130 and the CU 110 in a cloud-based RAN architecture (such as a vRAN architecture).

[0040] The SMO framework 105 may be configured to support RAN deployment and provisioning of non-virtualized network elements 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, which may be managed via an operation and maintenance interface (such as an O1 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 lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some specific implementations, the SMO framework 105 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 111) via the O1 interface. Additionally, in some specific implementations, the SMO framework 105 may communicate directly with one or more RUs 140 via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .

[0041] The non-RT RIC 115 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updating, 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 the near-RT RIC 125 (such as via an A1 interface). The near-RT RIC 125 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 110, one or more DUs 130, or both, and the O-eNB with the near-RT RIC 125.

[0042] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 125 and may be received from a non-network data source or from a network function at the SMO framework 105 or the non-RT RIC 115. 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 of performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0043] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Therefore, the base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component is indicated by a dotted line to indicate that each component may be included in the base station 102 or may not be included in the base station). The base station 102 provides an access point to the core network 120 for the UE 104. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). Small cells include femto cells, pico cells, and micro cells. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to RU 140 and / or downlink (DL) (also known as forward link) transmission from RU 140 to UE 104. The communication link may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link may be through one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum of up to Y MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.) bandwidth. These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL). Component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0044] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use 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). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0045] The wireless communication system may also include a Wi-Fi AP 150 that communicates with a UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in a 5 GHz unlicensed spectrum, etc. When communicating in an unlicensed spectrum, the UE 104 / AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0046] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5GNR, two initial operating bands have been 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 the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0047] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 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.

[0048] In view of the above, unless otherwise specified, if the term "6 GHz or less" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specified, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0049] The base station 102 and the UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. The base station 102 may send 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 send 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 direction and transmit direction for each of the base station 102 / UE 104. The transmit direction and receive direction of the base station 102 may be the same or may not be the same. The transmit direction and receive direction of the UE 104 may be the same or may not be the same.

[0050] The base station 102 may include and / or be referred to as a gNB, a Node B, an 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 transmit receive point (TRP), a network node, a network entity, a network equipment, or some other suitable term. The base station 102 may 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 a RU, or as a disaggregated base station including one or more of a CU, a DU, and / or a RU. A set of base stations that may include disaggregated base stations and / or aggregated base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0051] 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. AMF 161 is a control node that handles signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identity handling, access authorization, and subscription management. 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, in general, 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, LMF 166, position determination entity (PDE), serving mobile location center (SMLC), mobile positioning center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. LMF 166 receives measurement and assistance information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may determine the location of UE 104 using one or more positioning methods. Positioning UE 104 may involve signal measurements, positioning estimates, and speed calculations based on these measurements. Signal measurements may be performed by UE 104 and / or serving base station 102. The measured signals may be based on a satellite positioning system (SPS) 170 (e.g., one or more of a global navigation satellite system (GNSS), a global positioning system (GPS), a non-terrestrial network (NTN), or other satellite positioning / positioning systems), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., an atmospheric pressure sensor, a motion sensor), an NR enhanced cell ID (NR E-CID) method, 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 one or more of other systems / signals / sensors.

[0052] Examples of UE 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as stations, mobile stations, subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, user agents, mobile clients, clients, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more supporting devices, such as in a device cluster arrangement. One or more of these devices may access the network collectively and / or individually.

[0053] Reference again Figure 1In certain aspects, the UE 104 may have a PRS measurement component 198 configured to receive combined assistance data for a first set of LP-PRS, a second set of LP-PRS, a first set of associated DL-PRS, and a second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of associated DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. The PRS measurement component 198 may be configured to receive the first set of LP-PRS and the second set of LP-PRS via a first receiver. The PRS measurement component 198 may be configured to receive the first set of associated DL-PRS and the second set of associated DL-PRS via a second receiver. The second receiver may be different from the first receiver. The PRS measurement component 198 may be configured to measure the first set of LP-PRS and the second set of LP-PRS based on the combined assistance data. The PRS measurement component 198 may be configured to update a priority for measuring a first set of associated DL-PRS or a second set of associated DL-PRS based on the measured first set of LP-PRS and the measured second set of LP-PRS. In some aspects, the base station 102 may have a PRS association component 197 configured to send combined assistance data for the first set of LP-PRS, the second set of LP-PRS, the first set of associated DL-PRS, and the second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of associated DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. The PRS association component 197 may be configured to receive an indication of a priority for measuring a first set of associated DL-PRS or a second set of associated DL-PRS based on the first set of LP-PRS and the second set of LP-PRS. In certain aspects, the base station 102 may have a PRS transmission component 199 configured to transmit a first set of LP-PRS and a second set of LP-PRS to a first receiver of the UE. The PRS transmission component 199 may be configured to transmit a first set of associated DL-PRS and a second set of associated DL-PRS to a second receiver. The second receiver may be different from the first receiver. Although the following description may focus on using LP-PAA and MR for positioning, the concepts described herein may be applicable to positioning using any two receivers of a wireless device, where one receiver may have less power or functionality than the other receiver.Although the following description may focus on 5G NR, the concepts described herein may be applicable to other similar areas such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0054] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG280 is a diagram illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL, or may be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A , Figure 2C In the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are full DL and full UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE is configured with the slot format through the received slot format indicator (SFI) (dynamically configured through DL control information (DCI) or semi-statically / statically configured through radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0055] FIG. 2A to FIG. 2DThe frame structure is illustrated, and various aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 subframes of equal size (1ms). Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4 or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For a normal CP, each time slot may include 14 symbols, and for an extended CP, each time slot may include 12 symbols. The symbol on the DL may be a CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) extended OFDM (DFT-s-OFDM) symbol (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). Symbol length / duration can be scaled with 1 / SCS.

[0056]

[0057] Table 1: Parameter set, SCS and CP

[0058] For normal CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Thus, for normal CP and parameter set μ, there are 14 symbols / slot and 2 μ timeslots / subframe. The subcarrier spacing can be equal to 2 μ *15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example of a parameter set μ=2 with a normal CP of 14 symbols per slot and 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is about 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP may have a specific parameter set and CP (normal or extended).

[0059] A resource grid may be used to represent a frame structure. Each slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0060] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0061] Figure 2B Examples of various DL channels within a subframe of a frame are illustrated. A 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 a BWP may be referred to as a control resource set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during a PDCCH monitoring opportunity on a CORESET, wherein the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. A secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as an SS block (SSB)). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent over the PBCH (such as the system information block (SIB)), and paging messages.

[0062] like Figure 2CAs illustrated, some of the REs carry DM-RS (indicated as R for a particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may send a DM-RS for a physical uplink control channel (PUCCH) and a DM-RS for a physical uplink shared channel (PUSCH). The PUSCH DM-RS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DM-RS may be sent in different configurations. The UE may send a sounding reference signal (SRS). The SRS may be sent in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0063] Figure 2D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0064] Figure 3370 is a block diagram of a base station 310 in an access network communicating with a UE 350. 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 functions. 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 functions associated with broadcasting of system information (e.g., MIB, SIB), 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 functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with 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 functions 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.

[0065] The transmit (Tx) processor 316 and the receive (Rx) processor 370 implement layer 1 functions associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transmission channel, forward error correction (FEC) decoding of the transmission channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The Tx processor 316 handles the mapping to the signal constellation 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 decoded and modulated symbols can then be divided into parallel streams. Subsequently, each stream can be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived from reference signals and / or channel state feedback sent 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 for transmission using a corresponding spatial stream.

[0066] At the UE 350, each receiver 354Rx receives a signal through its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to a receive (Rx) processor 356. The Tx processor 368 and the Rx processor 356 implement layer 1 functions associated with various signal processing functions. The Rx processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined into a single OFDM symbol stream by the Rx processor 356. 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 point sent by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0067] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0068] Similar to the functions described in conjunction with DL transmission performed by the base station 310, the controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions 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.

[0069] Channel estimates derived by the channel estimator 358 from a reference signal or feedback sent by the base station 310 may be used by the Tx processor 368 to select appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the Tx processor 368 may be provided to different antennas 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0070] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to an Rx processor 370.

[0071] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0072] At least one of the Tx processor 368, the Rx processor 356, and the controller / processor 359 may be configured to perform Figure 1 The PRS measurement component 198 combines various aspects.

[0073] At least one of the Tx processor 316, the Rx processor 370, and the controller / processor 375 may be configured to perform Figure 1 At least one of the Tx processor 316, the Rx processor 370, and the controller / processor 375 may be configured to perform the Figure 1 The PRS sending component 199 combines various aspects.

[0074] Figure 4 4 is a diagram illustrating an example of UE positioning based on reference signal measurement. UE 404 may be at time T SRS_TX UL-SRS 412 is sent and at time T PRS_RX A DL positioning reference signal (PRS) (DL-PRS) 410 is received. TRP 406 may be at time T SRS_RX Receive UL-SRS 412 and at time T PRS_TX 410. UE 404 may receive DL-PRS 410 before transmitting UL-SRS 412, or may transmit UL-SRS 412 before receiving DL-PRS 410. In both cases, a positioning server (e.g., location server 168) or UE 404 may determine the UL-SRS 412 based on ||T SRS_RX –T PRS_TX |–|T SRS_TX –T PRS_RX || to determine RTT 414. Thus, multi-RTT positioning may utilize UE ERx-Tx time difference measurements (ie, |T SRS_TX –T PRS_RX |) and DL-PRS reference signal received power (RSRP) (DL-PRS-RSRP), and the measured TRP Rx-Tx time difference measurement (ie, |T SRS_RX –T PRS_TX|) and UL-SRS-RSRP. UE 404 measures UE Rx-Tx time difference measurement (and DL-PRS-RSRP of received signals) using assistance data received from the positioning server, and TRP 402, 406 measures gNB Rx-Tx time difference measurement (and UL-SRS-RSRP of received signals) using assistance data received from the positioning server. These measurements may be used at the positioning server or UE 404 to determine RTT, which is used to estimate the position of UE 404. Other methods for determining RTT are possible, such as, for example, using DL-TDOA and / or UL-TDOA measurements.

[0075] DL-AoD positioning may utilize the measured DL-PRS-RSRP of downlink signals received from multiple TRPs 402, 406 at the UE 404. The UE 404 measures the DL-PRS-RSRP of the received signals using assistance data received from a positioning server, and the resulting measurements, along with the departure azimuth angle (A-AoD), departure zenith angle (Z-AoD), and other configuration information, are used to position the UE 404 relative to neighboring TRPs 402, 406.

[0076] DL-TDOA positioning can utilize the DL Reference Signal Time Difference (RSTD) (and DL-PRS-RSRP) of downlink signals received from multiple TRPs 402, 406 at the UE 404. The UE 404 uses the assistance data received from the positioning server to measure the DL RSTD (and DL-PRS-RSRP) of the received signals, and uses the resulting measurements along with other configuration information to position the UE 404 relative to neighboring TRPs 402, 406.

[0077] UL-TDOA positioning can utilize the UL relative time of arrival (RTOA) (and UL-SRS-RSRP) of uplink signals sent from UE 404 at multiple TRPs 402, 406. TRPs 402, 406 use assistance data received from a positioning server to measure the UL-RTOA (and UL-SRS-RSRP) of the received signal, and use the resulting measurements along with other configuration information to estimate the position of UE 404.

[0078] UL-AoA positioning may utilize the measured azimuth angle of arrival (A-AoA) and zenith angle of arrival (Z-AoA) of uplink signals sent from the UE 404 at multiple TRPs 402, 406. The TRPs 402, 406 measure the A-AoA and Z-AoA of the received signals using assistance data received from a positioning server, and the resulting measurements are used together with other configuration information to estimate the position of the UE 404.

[0079] Additional positioning methods may be used to estimate the position of the UE 404, such as, for example, UE-side UL-AoD and / or DL-AoA. It should be noted that data / measurements from various techniques may be combined in various ways to increase accuracy, determine and / or enhance certainty, supplement / complete measurements, and / or replace / provide missing information.

[0080] Figure 5A 500 is a diagram illustrating a UE 502 that wirelessly communicates with a TRP 504 and a TRP 505. The UE 502 has a radio 506 that is in an off mode or a sleep mode (i.e., a deep sleep mode), and a radio 508 that is in an on mode or an active mode. The radio 506 may be, for example, a main radio (MR) of the UE 502. The radio 508 may be, for example, a low power (LP) wake-up receiver (LP-WUR) of the UE 502. The radio 508 may be a companion receiver that monitors for a LP wake-up signal (LP-WUS). The radio 508 may have lower power consumption than the radio 506. If the UE 502 is not scheduled to send or receive data within a certain time period, the UE 502 may be configured to switch the radio 506 to an off mode or a sleep mode during the time period. In other words, the UE 502 may be configured to switch the radio 506 to a sleep mode unless there is something to send. Radio 508 may be in active mode, which monitors reception of signals such as LP-WUS. Radio 506 and radio 508 may share antenna 510 to communicate with one or more network nodes, such as communicating with TRP 504 via communication 512 or communicating with TRP 505 via communication 513. UE 502 may be configured to monitor communication 512 from TRP 505 or communication 513 from TRP 504 to find signals such as LP-WUS. In some aspects, radio 506 and radio 508 may use separate antennas to communicate with one or more network nodes. Although UE 502 is shown as having two radios, in other aspects, UE may have more than two radios, such as three radios, four radios, or more radios with similar power consumption levels or with different power consumption levels. Radio 506 may also be referred to as a high power radio (HPR). Radio 508 may be referred to as a low power radio (LPR). Radio 506 may be configured to receive and measure an Orthogonal Frequency Division Multiplexing (OFDM) waveform. Radio 508 may be configured to receive and measure an On-Off Keying (OOK) waveform or an Amplitude Shift Keying based modulation waveform. Radio 508 may not be configured to receive and measure an OFDM waveform.

[0081] Figure 5B is an example Figure 5B 500 of a UE 502 with radio 506 switched to on or active mode and radio 508 switched to off or inactive mode or sleep mode. If UE 502 is scheduled to send or receive data during a certain time period, UE 502 can be configured to switch radio 506 to on mode or active mode during that time period. In other words, UE 502 can be configured to switch radio 506 to active mode when there is something to send.

[0082] In some aspects, the TRP 504 may send a communication 512 including the on-demand LP-WUS to the radio 508 of the UE 502. In some aspects, the TRP 505 may send a communication 513 including the on-demand LP-WUS to the radio 508 of the UE 502. In response, the UE 502 may switch the radio 506 from Figure 5A Switch to inactive mode in Figure 5B When radio 506 is in active mode, UE 502 may send and receive data with TRP 504 via radio 506 using communication 552, or may send and receive data with TRP 505 via radio 506 using communication 513.

[0083] Using a low power radio, such as radio 508, can reduce overall power consumption and latency at UE 502 by minimizing the time that radio 506 is in active mode. If radio 506 is expensive in terms of power consumption, avoiding unnecessary wake-up of radio 506 can reduce power consumption at UE 502. If radio 508 consumes very low power compared to radio 506, radio 508 can be configured to frequently monitor LP-WUS signals during communication 512 or communication 513 to meet latency conditions of UE 502. In some aspects, radio 508 can be configured for paging reception from TRP 504 and / or TRP 505. In some aspects, radio 508 can be configured to monitor other LP signals, such as LP reference signal (LP-RS). UE 502 can use LP-RS for time tracking or frequency tracking. UE 502 can use LP-RS for radio resource management (RRM) measurements. By monitoring the LP-RS signal, UE 502 can offload serving cell RRM from radio 506 to radio 508 to reduce the frequency with which radio 506 is in active mode and help save power at UE 502 .

[0084] Figure 6is a UE 602 (such as a UE 604) configured to communicate with a serving network node 604, one or more neighbor network nodes (such as a neighbor network node 606), and a location management function (LMF) 608. Figure 1 UE 104 or Figure 5A and Figure 5B 600 of a communication flow diagram of a UE 502 in FIG. 600. In some aspects, the UE 602 may be configured to perform positioning measurements when the UE 602 is in a radio resource control (RRC) inactive state. By configuring the UE 602 to perform positioning measurements when the UE 602 is in an RRC inactive state, the UE 602 may perform positioning measurements without switching to an RRC connected mode or an RRC connected state. The UE 602 may have an HPR, such as Figure 5A and Figure 5B In the radio component 506 in the HPR, the HPR can measure DL-PRS signals from network nodes, such as the DL-PRS set 626 from the serving network node 604 or the DL-PRS set 628 from the neighbor network node 606.

[0085] UE 602 may send UE capabilities 609 to serving network node 604. UE capabilities 609 may include an indicator of the ability of UE 602 to receive and / or measure a DL-PRS set. For example, UE capabilities 609 may indicate a maximum number of resources that UE 602 can read within a certain period of time.

[0086] The assistance information controller 610 may be configured to communicate with the serving network node 604, the neighboring network node 606, and the LMF 608. The assistance information controller 610 may be, for example, Figure 1 120, near RT RIC 125, or non-RT RIC 115 in the core network 120, near RT RIC 125, or non-RT RIC 115 in the core network 120. When the UE 602 is in the RRC inactive mode, the auxiliary data controller 610 can provide auxiliary data to support downlink (DL) positioning. In one aspect, the LMF 608 can use the auxiliary information controller 610 to generate a long-term evolution (LTE) positioning protocol (LPP) message to configure the UE 602 for DL ​​positioning. The LPP message may include, for example, a non-access stratum (NAS) message. The LMF 608 can send the LPP 612 to the UE 602. The UE 602 can receive the LPP 612 from the LMF 608. In other aspects, the serving network node 604 can use the auxiliary information controller 610 to generate a positioning system information block (posSIB) to configure the UE 602 for DL ​​positioning. The serving network node 604 can send the posSIB 614 to the UE 602. The UE 602 can receive the posSIB from the serving network node.

[0087] At 616, UE 602 may switch to RRC inactive mode. UE 602 may have been preconfigured for DL ​​positioning using LPP 612 and / or posSIB 614. At 630, UE 602 may perform positioning measurements based on the received set of DL-PRS. Serving network node 604 may send a set of DL-PRS 626 that may be used for positioning. Neighboring network node 606 may send a set of DL-PRS 628 that may be used for positioning. UE 602 may have an HPR configured to be in active mode to receive the set of DL-PRS. UE 602 may receive the set of DL-PRS 626 from serving network node 604. UE 602 may receive the set of DL-PRS 628 from neighboring network node 606. Although in Figure 6 One neighbor network node is shown in the communication flow diagram 600 in FIG. 6 , but in other aspects, the UE 602 may receive DL-PRS from multiple neighbor network nodes.

[0088] At 630, the UE 602 may measure a DL-PRS set. The UE 602 may measure a DL-PRS set 626 received from the serving network node 604. The UE 602 may measure a DL-PRS set 628 received from the neighbor network node 606. In some aspects, the UE 602 may send a measurement report as an uplink (UL) small data transmission (UL-SDT) 632 to the serving network node 604. The UE 602 may send the UL-SDT 632 from its HDR. In some aspects, the UE 602 may send a location service (LCS) event report 634 to the LMF 608. The LCS event report 634 may be based on the measurements taken at 630. The UE 602 may send the LCS event report 634 from its HDR. In summary, UE 602 may send the measurements it took at 630 without transitioning to the RRC connected state, thereby remaining in the RRC inactive mode while sending the UL-SDT 632 and / or LCS event report 634.

[0089] In some aspects, the DL-PRS (such as DL-PRS set 626 and DL-PRS set 628) may exceed the ability of the UE 602 to receive and measure each of the DL-PRS. If the auxiliary data exceeds the ability of the UE 602 to process the DL-PRS, the UE 602 may be configured to prioritize the DL-PRS so as to measure a subset of the DL-PRS with the highest priority to the UE 602. In some aspects, the LMF 608 may determine the priority of the configured DL-PRS resources. For example, for each frequency layer, multiple TRPs (e.g., up to 64 TRPs) may be ranked according to priority. For each TRP in the multiple TRPs, the LMF 608 may rank up to two DL-PRS resource sets according to priority. The DL-PRS resource sets (e.g., up to 2 DL-PRS resource sets for up to 64 TRPs) may be ranked in descending order of priority for measurement. If the total number of DL-PRS resource sets exceeds the reported capability of UE 602, UE 602 may measure a subset of DL-PRS resource sets with the highest priority.

[0090] The UE 602 may be configured to prioritize the subset of DL-PRS in any suitable manner, such as by prioritizing DL-PRS from TRPs that are physically closer to the UE 602. However, when the UE 602 is in an RRC connected state, the UE may prioritize the set of DL-PRS 626 from the serving network node 604 over the set of DL-PRS 628 from the neighbor network node 606 in response to detecting that the UE 602 is closer to the serving network node 604 than the neighbor network node 606, but may move closer to the neighbor network node 606 when the UE 602 is in an RRC inactive state. This may negatively impact positioning accuracy and positioning efficiency at the UE 602 because the UE 602 may no longer prioritize receiving and measuring DL-PRS from closer network nodes.

[0091] Although a UE 602 in an RRC inactive state may be configured to periodically measure all DL-PRS using its HPR for measuring DL-PRS, using the HPR so frequently may consume a lot of power. In some aspects, the UE 602 may configure the DL-PRS set 626 and the DL-PRS set 628 to align with the paging discontinuous reception (DRX) cycle of the UE 602, which may allow the UE 602 to put its HPR to sleep and periodically switch to active mode to receive DL-PRS. However, the network may send DL-PRS to multiple UEs in a cell, and the paging DRX cycle may be specific to each UE. Configuring the DL-PRS set 626 and the DL-PRS set 628 to align with the paging DRX cycle of the UE 602 may prevent other UEs from receiving DL-PRS that are not aligned with the DRX cycle of the UE 602. Although the network may adjust the configuration (e.g., periodicity, offset, duration) of the DL-PRS for some UEs in the RRC connected mode, the network may not be able to adjust the configuration of the DL-PRS for UEs in the RRC inactive mode. In some aspects, the UE 602 may be configured to monitor the DL-PRS set using the LPR rather than the HDR of the UE. However, some LPRs may not be configured to receive the DL-PRS set using an OFDM waveform. For example, the serving network node 604 may use an OFDM waveform to send the DL-PRS set 626, but the LPR of the UE 602 may have a lower complexity decoder that does not support OFDM waveforms (e.g., based on an envelope detector). In addition, due to limited measurement capabilities and narrowband capabilities, some LPRs may not provide the same positioning accuracy as the HPR of the UE 602. The assistance data of LPP 612 and / or posSIB 614 may configure UE 602 to perform a DL-TDOA positioning technique or a multi-cell round trip time (RTT) positioning technique, where the path delay is measured and the accuracy of the technique is dependent on the bandwidth of the measured signal. An LPR with limited ability to measure bandwidth may not be able to accurately perform such positioning techniques.

[0092] Therefore, it may be beneficial to improve positioning techniques using LPR to save power at the UE, for example, by performing joint positioning with both LPR and HPR to save power at the UE. In some aspects, the UE may be configured to receive combined assistance data for a first set of LP-PRS, a second set of LP-PRS, a first set of associated DL-PRS, and a second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. The UE may be configured to receive the first set of LP-PRS and the second set of LP-PRS via a first receiver. The UE may be configured to receive the first set of DL-PRS and the second set of associated DL-PRS via a second receiver. The second receiver may be different from the first receiver. The UE may be configured to measure the first set of LP-PRS and the second set of LP-PRS based on the combined assistance data. The UE may be configured to update a priority for measuring a first set of DL-PRS or a second set of associated DL-PRS based on the measured first set of LP-PRS and the measured second set of LP-PRS. The first network node may be configured to send combined assistance data for the first set of LP-PRS, the second set of LP-PRS, the first set of associated DL-PRS, and the second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. The first network node may be configured to receive an indication of a priority for measuring the first set of DL-PRS or the second set of associated DL-PRS based on the first set of LP-PRS and the second set of LP-PRS. The second network node may be configured to send the first set of LP-PRS and the second set of LP-PRS from the first TRP to the first receiver of the UE. The second network node may be configured to send the first set of associated DL-PRS and the second set of associated DL-PRS from the second TRP to the second receiver. The second receiver may be different from the first receiver.

[0093] Figure 7 is a UE 702 (such as a neighbor network node 706) configured to communicate with a serving network node 704, one or more neighbor network nodes (such as a neighbor network node 706), and a LMF 708. Figure 1 UE 104 or Figure 5A and Figure 5B700 of a communication flow diagram of a UE 502 in FIG. 700. In some aspects, the UE 702 may be configured to perform positioning measurements when the UE 702 is in an RRC inactive state. By configuring the UE 702 to perform positioning measurements when the UE 702 is in an RRC inactive state, the UE 702 may perform positioning measurements without switching to an RRC connected mode or an RRC connected state. The UE 702 may have an HPR, such as Figure 5A and Figure 5B The HPR may measure DL-PRS signals from network nodes, such as DL-PRS set 726 from serving network node 704 or DL-PRS set 728 from neighboring network node 706. UE 702 may also have LPRs, such as Figure 5A and Figure 5B 5 , the HPR may measure LP-PRS signals from network nodes, such as LP-PRS set 718 from serving network node 704 or LP-PRS set 720 from neighboring network node 706. Serving network node 704, neighboring network node 706, and LMF 708 may be considered as components of network 705 that communicate with each other, for example, via a plurality of backhaul links and / or midhaul links.

[0094] The DL-PRS may be sent using a high complexity waveform that the LPR of the UE 702 may not be configured to receive and measure. For example, the DL-PRS set 726 and / or the DL-PRS set 728 may be sent using an OFDM waveform. The LP-PRS may be sent using a low complexity waveform that the LPR of the UE 702 may be configured to receive and measure. For example, the LP-PRS set 718 and / or the LP-PRS set 720 may be sent using an OOK waveform or an amplitude shift keying based modulation waveform.

[0095] UE 702 may send UE capabilities 709 to serving network node 704. UE capabilities 709 may include an indicator of the ability of UE 702 to receive and / or measure a DL-PRS set and / or a LP-PRS set. For example, UE capabilities 709 may indicate a maximum number of resources that UE 702 can read within a certain period of time. The maximum number of resources for DL-PRS and LP-PRS may be indicated separately based on the capabilities of the corresponding receivers.

[0096] The assistance information controller 710 may be configured to communicate with the serving network node 704, the neighboring network node 706, and the LMF 708. The assistance information controller 710 may be, for example, Figure 1120, near RT RIC 125, or non-RT RIC 115 in the core network 120, near RT RIC 125, or non-RT RIC 115 in the core network 120. When the UE 702 is in the RRC inactive mode, the auxiliary data controller 710 can provide auxiliary data to support downlink (DL) positioning. In one aspect, the LMF 708 can use the auxiliary information controller 710 to generate a long-term evolution (LTE) positioning protocol (LPP) message to configure the UE 702 for DL ​​positioning. The LPP message may include, for example, a non-access stratum (NAS) message. The LMF 708 can send the LPP 712 to the UE 702. The UE 702 can receive the LPP 712 from the LMF 708. In other aspects, the serving network node 704 can use the auxiliary information controller 710 to generate a positioning system information block (posSIB) to configure the UE 702 for DL ​​positioning. The serving network node 704 can send the posSIB 714 to the UE 702. The UE 702 can receive the posSIB from the serving network node. LPP 712 and / or posSIB 714 may include combined assistance data configuring an LP-PRS set and a DL-PRS set sent to UE 702, such as an LP-PRS set 718 from the serving network node 704, an LP-PRS set 720 from the neighboring network node 706, a DL-PRS set 726 from the serving network node 704, and / or a DL-PRS set from the neighboring network node 706.

[0097] The assistance data may include combined data including a configuration of associations between a first set of LP-PRSs and a first set of DL-PRSs and a second set of LP-PRSs and an associated second set of DL-PRSs. For example, the assistance data may associate a set of LP-PRSs 718 from a serving network node 704 with a set of DL-PRSs 726 from the serving network node 704, and may associate a set of LP-PRSs 720 from a neighboring network node 706 with a set of DL-PRSs 728 from the neighboring network node 706. In some aspects, the assistance data may distinguish between a set of LP-PRSs or a set of DL-PRSs from the same TRP. Examples of assistance data configurations are shown below as Table 2.

[0098]

[0099]

[0100] Table 2

[0101] The above table shows the TRP-level and PRS resource set-level associations between various LP-PRS and DL-PRS. The network may send three LP-PRS sets to the UE: [LP-PRS#1], [LP-PRS#2], and [LP-PRS#3, LP-PRS#4]. The network may also send three DL-PRS sets to the UE: [DL-PRS#1, DL-PRS#2, DL-PRS#3], [DL-PRS#4, DL-PRS#5, DL-PRS#6], and [DL-PRS#7, DL-PRS#8, DL-PRS#9]. The auxiliary data may associate the LP-PRS set [LP-PRS #1] with the DL-PRS set [DL-PRS #1, DL-PRS #2, DL-PRS #3], may associate the LP-PRS set [LP-PRS #2] with the DL-PRS set [DL-PRS #4, DL-PRS #5, DL-PRS #6], and may associate the LP-PRS set [LP-PRS #3, LP-PRS #4] with the DL-PRS set [DL-PRS #7, DL-PRS #8, DL-PRS #9]. The associated DL-PRS may be an associated DL-PRS associated with at least one LP-PRS.

[0102] The combined assistance data between the LP-PRS set and the DL-PRS set may be at the TRP level (i.e., TRP level association), the PRS resource set level (i.e., PRS resource set level association), or the resource level (i.e., resource level association). In one aspect, the combined assistance data between the LP-PRS set and the DL-PRS set at the TRP level may associate the LP-PRS transmitted from the TRP with the DL-PRS transmitted from the same TRP. For example, the LP-PRS set [LP-PRS#1] transmitted from TRP#1 in Table 2 may be associated with the DL-PRS set [DL-PRS#1, DL-PRS#2, DL-PRS#3] transmitted from TRP#1 in Table 2. In another example, the LP-PRS set transmitted from the serving network node 704 may be associated with the DL-PRS set [DL-PRS#1, DL-PRS#2, DL-PRS#3] transmitted from the serving network node 704. Figure 7 The LP-PRS set 718 in the service network node 704 may be transmitted from the service network node 704. Figure 7726 in the LP-PRS set. In one aspect, the combined assistance data between the LP-PRS set and the DL-PRS set at the PRS resource set level may associate the LP-PRS set with the DL-PRS set based on the boresight direction information (i.e., azimuth and / or elevation). For example, in Table 2, the LP-PRS set [LP-PRS #2] may be associated with the DL-PRS set [DL-PRS #4, DL-PRS #5, DL-PRS #6], and the LP-PRS set [LP-PRS #3, LP-PRS #4] may be associated with the DL-PRS set [DL-PRS #7, DL-PRS #8, DL-PRS #9]. Although each of the PRSs [LP-PRS#2, LP-PRS#3, LP-PRS#4, DL-PRS#4, DL-PRS#5, DL-PRS#6, DL-PRS#7, DL-PRS#8, DL-PRS#9] may be transmitted from the same TRP#2, they may belong to different associated sets. The combined assistance data may include line-of-sight direction information for each LP-PRS resource and each DL-PRS resource, and the UE 702 may establish an association (e.g., beam-level association) between the LP-PRS resource and the DL-PRS resource based on the same line-of-sight direction value. In one aspect, the combined assistance data between the LP-PRS set and the DL-PRS set at the resource level may explicitly associate each LP-PRS with the DL-PRS. Each LP-PRS resource may correspond to one or more DL-PRS resources in another DL-PRS resource set of the same TRP. In other words, while the TRP-level association may identify the association between an LP-PRS or DL-PRS and a TRP, and the PRS resource set-level association may identify the association between an LP-PRS set and a DL-PRS set, the resource-level association may identify the association between a unique identifier of an LP-PRS and a unique identifier of a DL-PRS.

[0103] The combined assistance data of the LPP 712 and / or posSIB 714 may provide the UE 702 with a spatial relationship between the LP-PRS set and the DL-PRS set (e.g., associating PRSs using the same or adjacent Tx beam from the TRP to the UE 702). Since the combined assistance data may associate any set of LP-PRS with any other set of DL-PRS, the UE 602 may not restrict the association to measure the associated resources of the LP-PRS set and the associated set of DL-PRS through the same Rx beam. The UE 602 may use the combined assistance data to determine the processing priority of the DL-PRS resources or to perform beam refinement for DL ​​Angle of Departure (DL-AoD), as explained below.

[0104] At 716, UE 702 may switch to RRC inactive mode. UE 702 may have been preconfigured for DL ​​positioning using LPP 712 and / or posSIB 714 via combined assistance data. Serving network node 704 may send LP-PRS set 718 to UE 702. UE may receive LP-PRS set 718 from serving network node 704. Neighboring network node 706 may send LP-PRS set 720 to UE 702. UE may receive LP-PRS set 720 from neighboring network node 706. At 722, UE 702 may perform positioning measurements based on the LP-PRS set received by UE 702 and configured by the combined assistance data. UE 702 may have an LPR configured to be in active mode to receive the LP-PRS set. UE 702 may receive LP-PRS set 718 from serving network node 704. UE 702 may receive LP-PRS set 720 from neighbor network node 706. Figure 7 One neighbor network node is shown in the communication flow diagram 700 in FIG. 7 , but in other aspects, the UE 702 may receive LP-PRS from multiple neighbor network nodes.

[0105] At 722, the UE 702 may measure a set of LP-PRSs. The UE 702 may measure a set of LP-PRSs 718 received from the serving network node 704. The UE 702 may measure a set of LP-PRSs 720 received from the neighbor network node 706. The UE 702 may prioritize measurements of a set of DL-PRSs based on the measurements of the set of LP-PRSs. Since the combined assistance data may associate a set of LP-PRSs with a set of DL-PRSs, the UE 702 may prioritize the LP-PRSs based on the measurements and may update the priority of the DL-PRSs using the prioritized list of LP-PRSs. The UE 702 may prioritize the LP-PRSs based on the measurements in any suitable manner. For example, UE 702 may rank the LP-PRSs based on the measured RSRP or RSSI of each LP-PRS, such that the LP-PRS with the highest RSRP or RSSI is ranked with the highest priority, and the LP-PRS with the lowest RSRP is ranked with the lowest priority. Then, UE 702 may rank the associated DL-PRS resources or the associated set of DL-PRSs according to the associated set of DL-PRSs of the UE. For example, referring back to Table 2, UE 702 may calculate that LP-PRS#2 has the highest RSRP, followed by LP-PRS#3, and then LP-PRS#1. The UE 702 may then re-prioritize the DL-PRS sets so that the DL-PRS set [DL-PRS #4, DL-PRS #5, DL-PRS #6] is prioritized highest, followed by the DL-PRS set [DL-PRS #7, DL-PRS #8, DL-PRS #9], and finally the DL-PRS set [DL-PRS #1, DL-PRS #2, DL-PRS #3]. The priority order list of the LP-PRS sets may be periodically updated to support potential changes in the location and / or positioning of the UE 702 over time.

[0106] At 730, UE 702 may perform positioning measurements based on the DL-PRS set received by UE 702. Serving network node 704 may send a DL-PRS set 726 that may be used for positioning. Neighboring network node 706 may send a DL-PRS set 728 that may be used for positioning. UE 702 may have an HPR configured to be in active mode to receive the DL-PRS set. The HPR of UE 702 may receive the DL-PRS set 726 from serving network node 704. The HPR of UE 702 may receive the DL-PRS set 728 from neighboring network node 706. Although in Figure 7One neighbor network node is shown in the communication flow diagram 700 in FIG. 7 , but in other aspects, the UE 702 may receive DL-PRS from multiple neighbor network nodes.

[0107] At 730, UE 702 may measure the DL-PRS set. At 722, UE 702 may update the priority of measuring the DL-PRS set based on the priority of the associated set of LP-PRS. For example, if returning to reference Table 2, if UE 702 calculates that LP-PRS#2 has the highest RSRP, followed by LP-PRS#3, and then LP-PRS#1, then UE 702 may prioritize measuring the DL-PRS set [DL-PRS#4, DL-PRS#5, DL-PRS#6] as the highest priority. If UE 702 has the capability to measure additional DL-PRS, UE 702 may measure the DL-PRS set [DL-PRS#7, DL-PRS#8, DL-PRS#9]. If UE 702 has the capability to measure additional DL-PRS, UE 702 may measure the DL-PRS set [DL-PRS#1, DL-PRS#2, DL-PRS#3] last.

[0108] In some aspects, the UE 702 may send the measurement report as an uplink (UL) small data transmission (UL-SDT) 732 to the serving network node 704. The UE 702 may send the UL-SDT 732 from its HDR. In some aspects, the UE 702 may send an LCS event report 734 to the LMF 708. The LCS event report 734 may be based on the measurements taken at 730. The UE 702 may send the LCS event report 734 from its HDR. In summary, the UE 702 may send its measurements taken at 730 without transitioning to an RRC connected state, thereby accurately prioritizing the DL-PRS using the measurements of the LP-PRS at 722, while remaining in an RRC inactive mode to send the UL-SDT 732 and / or the LCS event report 734.

[0109] Figure 8 is a UE 802 (such as a neighbor network node 806) configured to communicate with a serving network node 804, one or more neighbor network nodes (such as a neighbor network node 806), and a LMF 808. Figure 1 UE 104 or Figure 5A and Figure 5B UE 802 in the communication flow diagram 800. UE 802 can be configured to perform positioning measurements when UE 802 is in the RRC inactive state, similar to Figure 7 UE 702 in. UE 802 may have an HPR, such as Figure 5A and Figure 5B The HPR may measure DL-PRS signals from network nodes, such as DL-PRS set 826 from serving network node 804 or DL-PRS set 828 from neighboring network node 806. UE 802 may also have LPRs, such as Figure 5A and Figure 5B 806, the HPR may measure LP-PRS signals from network nodes, such as LP-PRS set 818 from serving network node 804 or LP-PRS set 820 from neighboring network node 806. Serving network node 804, neighboring network node 806, and LMF 808 may be considered as components of a network 805 that communicate with each other, for example, via a plurality of backhaul links and / or midhaul links.

[0110] The DL-PRS may be sent using a high complexity waveform that the LPR of the UE 802 may not be configured to receive and measure. For example, the DL-PRS set 826 and / or the DL-PRS set 828 may be sent using an OFDM waveform. The LP-PRS may be sent using a low complexity waveform that the LPR of the UE 802 may be configured to receive and measure. For example, the LP-PRS set 818 and / or the LP-PRS set 820 may be sent using an OOK waveform or an amplitude shift keying based modulation waveform.

[0111] UE 802 may send UE capabilities 809 to serving network node 804. UE capabilities 809 may include an indicator of the ability of UE 802 to receive and / or measure a DL-PRS set and / or a LP-PRS set. For example, UE capabilities 809 may indicate a maximum number of resources that UE 802 can read within a certain period of time.

[0112] The assistance information controller 810 may be configured to communicate with the serving network node 804, the neighboring network node 806, and the LMF 808. The assistance information controller 810 may be, for example, Figure 1120, near RT RIC 125, or non-RT RIC 115 in the core network 120, near RT RIC 125, or non-RT RIC 115 in the core network 120. When the UE 802 is in the RRC inactive mode, the auxiliary data controller 810 can provide auxiliary data to support downlink (DL) positioning. In one aspect, the LMF 808 can use the auxiliary information controller 810 to generate a long-term evolution (LTE) positioning protocol (LPP) message to configure the UE 802 for DL ​​positioning. The LPP message may include, for example, a non-access stratum (NAS) message. The LMF 808 can send the LPP 812 to the UE 802. The UE 802 can receive the LPP 812 from the LMF 808. In other aspects, the serving network node 804 can use the auxiliary information controller 810 to generate a positioning system information block (posSIB) to configure the UE 802 for DL ​​positioning. The serving network node 804 can send the posSIB 814 to the UE 802. The UE 802 can receive the posSIB from the serving network node. The LPP 812 and / or posSIB 814 may include combined assistance data configuring an LP-PRS set and a DL-PRS set sent to the UE 802, such as an LP-PRS set 818 from the serving network node 804, an LP-PRS set 820 from the neighboring network node 806, a DL-PRS set 826 from the serving network node 804, and / or a DL-PRS set from the neighboring network node 806.

[0113] The auxiliary data can be similar to Figure 7 The auxiliary data may also be represented by Table 2 above.

[0114] At 816, UE 802 may switch to RRC inactive mode. UE 802 may have been preconfigured for DL ​​positioning using LPP 812 and / or posSIB 814 via combined assistance data. Serving network node 804 may send LP-PRS set 818 to UE 802. UE may receive LP-PRS set 818 from serving network node 804. Neighboring network node 806 may send LP-PRS set 820 to UE 802. UE may receive LP-PRS set 820 from neighboring network node 806. At 822, UE 802 may perform positioning measurements based on the LP-PRS set received by UE 802 and configured by the combined assistance data. UE 802 may have an LPR configured to be in active mode to receive the LP-PRS set. UE 802 may receive LP-PRS set 818 from serving network node 804. UE 802 may receive LP-PRS set 820 from neighbor network node 806. Figure 8One neighbor network node is shown in the communication flow diagram 800 in FIG. 8 , but in other aspects, the UE 802 may receive LP-PRS from multiple neighbor network nodes.

[0115] At 822, UE 802 may measure a set of LP-PRSs. UE 802 may measure a set of LP-PRSs 818 received from serving network node 804. UE 802 may measure a set of LP-PRSs 820 received from neighbor network node 806. In some aspects, UE 802 may use the measurement of the set of LP-PRSs to perform a first step of a two-step beam refinement for DL-AoD. For example, each TRP of serving network node 804 may transmit set of LP-PRSs 818 using a relatively wide beam, and each TRP of neighbor network node 806 may transmit set of LP-PRSs 820 using a relatively wide beam.

[0116] At 822, the UE 802 may measure the RSRP of each of the LP-PRS set 818 and the LP-PRS set 820. The UE 802 may send a measurement report 824 of the most suitable RSRP to the LMF 808 based on the measurements taken at 822. The LMF 808 may receive the measurement report 824 from the UE 802. At 823, the LMF 808 may estimate a rough position of the UE 802 based on the measurement report 824. The LMF 808 may send a DL-PRS resource set 825 to the UE 802. The UE 802 may receive the DL-PRS resource set 825 from the LMF 808. The DL-PRS resource set 825 may indicate the DL-PRS resource corresponding to the strongest narrow beam from the TRP with the most suitable measured RSRP. The DL-PRS resource 825 may be sent as an LPP. The DL-PRS resource 825 may be sent as assistance data. In some aspects, the assistance data may indicate what additional DL-PRS resources the UE 802 may report for each LP-PRS.

[0117] At 830, the UE 802 may perform positioning measurements based on the DL-PRS resource set 825 received from the LMF 808. The UE 802 may send an updated measurement report 836 based on the DL-PRS resource set 825. The LMF 808 may receive the updated measurement report 836 from the UE 802. In summary, the UE 802 may use its LPR at 822 to measure the LP-PRS resource set with a wide beam as the LP-PRS set 818 and the LP-PRS set 820. Using the association information received as the DL-PRS resource set 825 received from the LMF 808, the UE 802 may use its HPR at 830 to measure the DL-PRS resources associated with the LP-PRS resource set with a narrow beam.

At 902, the UE may receive combined assistance data for a first set of LP-PRS, a second set of LP-PRS, a first set of associated DL-PRS, and a second set of associated DL-PRS. The combined assistance data may include a first association configuration between the first set of LP-PRS and the first set of associated DL-PRS and a second association configuration between the second set of LP-PRS and the second set of associated DL-PRS. For example, 902 may be performed by Figure 7 720, DL-PRS set 726, and DL-PRS set 728 as the LPP 712 from the LMF 708 and / or the posSIB 714 from the serving network node 704. The combined assistance data may include a first association configuration between the LP-PRS set 718 and the DL-PRS set 726 and a second association configuration between the LP-PRS set 720 and the DL-PRS set 728. In addition, 902 may be performed by Fig.12 Component 198 in is executed.

[0119] At 904, the UE may receive a first set of LP-PRS and a second set of LP-PRS via a first receiver, and receive a first set of associated DL-PRS and a second set of associated DL-PRS via a second receiver. The second receiver may be different from the first receiver. For example, 904 may be Figure 7 702 in the embodiment of the present invention may receive an LP-PRS set 718 from a serving network node 704 and an LP-PRS set 720 from a neighboring network node 706 via an LPR at the UE 702, and receive a DL-PRS set 726 from the serving network node 704 and a DL-PRS set 728 from the neighboring network node 706 via an HPR at the UE 702.

The UE 702 may update the priority of a subset of the DL-PRS resource set based on the measured LP-PRS set 718 and the measured LP-PRS set 720. In one aspect, for each L-PRS, there may be an associated subset of DL-PRS resources. If the UE 702 assumes that one LP-PRS is a high priority based on the measurement of the LP-PRS, then in response, the UE 702 may assume that the associated DL-PRS is a high priority. UE 702 may update the priority for measuring DL-PRS set 726 or DL-PRS set 728 based on the RSRP associated with LP-PRS set 718 and the RSRP set associated with LP-PRS set 720 at 722.
