Abstract

A first network node or a second network node may transmit assistance data to a first radio at a user equipment (UE), which assistance data may include a configuration of a set of low power (LP) positioning reference signals (LP-PRS). The UE may receive the assistance data via the first radio. The first network node may transmit the set of LP-PRSs to a second radio at the UE. The UE may receive the set of LP-PRSs via the second radio. The second radio may have a lower power consumption than the first radio. In one embodiment, a first network node may transmit an LP wake-up signal (LP-WUS) that includes an indication to measure a set of LP-PRSs. The UE may receive the LP-WUS via a second radio component. The UE may measure the set of LP-PRSs based on the configuration of the set of LP-PRSs and in response to receiving the LP-WUS.

Description

Technical Field

[0001] The present disclosure relates generally to communication systems and, more particularly, to systems of wireless devices having a low power receiver (LPR) and / or a high power receiver (HPR). Background Art

[0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology 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 the city, national, regional, and even global levels. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the ongoing evolution of mobile broadband 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 communication (mMTC), and ultra-reliable low latency communication (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. Additionally, these improvements may also apply 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 in order to provide a basic understanding of these aspects. This summary is not an extensive overview of all contemplated aspects. The summary neither identifies key or critical 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 the more detailed description that is presented later.

The device may receive the set of LP-PRSs via a second radio component. The second radio component may have lower power consumption than the first radio component. The device may measure the set of LP-PRSs based on the configuration of the set of LP-PRSs.

[0006] In one aspect of the present disclosure, a method, a computer-readable medium, and a device at a first network node are provided. The device may send a set of LP-PRSs to a second radio component at the UE.

The first network node may include a transmit receive point (TRP).

[0007] In one aspect of the present disclosure, a method, a computer-readable medium, and a device at a second network node are provided. The device may send auxiliary data to a first radio component at the UE, and the auxiliary data may include a configuration of a first set of LP-PRSs.

[0036] The detailed description set forth below in connection with the accompanying drawings is a description of various configurations and does not represent the only configurations in which the concepts described herein may be practiced. For a thorough understanding of the various concepts, the detailed description includes specific details. However, the concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0037] Certain aspects of a telecommunications system are presented with reference to various devices and methods. These devices and methods are described in the following detailed description and illustrated in the 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 an element is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0038] As an example, an element, or any portion of an element, or any combination of elements can be implemented as a "processing system" that 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, system on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic components, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in the processing system can execute software. Software should be broadly construed to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, execution threads, procedures, functions, or any combination thereof, regardless of whether it is referred to as software, firmware, middleware, microcode, hardware description language, or other terms.

[0039] Thus, in one or more example aspects, embodiments, and / or use cases, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality can be stored or encoded on a computer-readable medium as one or more instructions or code. Computer-readable media includes computer storage media. Storage media can be any available media that can be accessed by a computer. By way of example, such computer-readable media can 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 capable of storing computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0040] While aspects, embodiments, and / or use cases are described by way of some examples in this application, additional or different aspects, embodiments, and use cases may arise in many different arrangements and scenarios. The aspects, embodiments, and / or use cases described herein may be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, aspects, embodiments, and / or use cases may be embodied via integrated chips and other non-module-component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchase devices, medical devices, artificial intelligence (AI)-enabled devices, etc.). Although some examples may or may not be specifically targeted at a use case or application, the examples described may have wide applicability. Aspects, embodiments, and / or use cases may range from chip-level or modular components to non-modular, non-chip-level embodiments, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the techniques herein. In some practical settings, devices incorporating the 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 includes 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 techniques described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated components, or disaggregated components, end-user devices, etc., of various sizes, shapes, and configurations.

[0041] The deployment of a communication system such as a 5G NR system can be arranged in many ways using various components or constituent parts. In a 5G NR system or network, network nodes, network entities, mobility elements of the network, radio access network (RAN) nodes, core network nodes, network elements, or 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), transmit receive point (TRP), or cell, etc.) may be implemented as an aggregated base station (also referred to as a stand-alone BS or monolithic BS) or a disaggregated base station.

[0042] A converged 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 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 among one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and 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).

[0043] Base station operation or network design may consider the converged 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 a network configuration as advocated 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 virtually distributing the functionality of at least one unit, which may enable flexibility in network design. The various units of a disaggregated base station or a disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0044] Figure 1 FIG. 100 is a diagram 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 respective midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via respective fronthaul links. The RU 140 may communicate with a respective UE 104 via one or more radio frequency (RF) access links. In some embodiments, the UE 104 may be served simultaneously by multiple RUs 140.

[0045] Each of these units (i.e., CU 110, DU 130, RU 140, and the near RT RIC 125, non-RT RIC 115, and SMO framework 105) may include one or more interfaces or be coupled to one or more interfaces that are configured to receive or transmit signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or the 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 the transmission medium. For example, the units may include a wired interface that is configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium. Additionally, the units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) that is configured to receive and / or transmit signals to one or more of the other units via a wireless transmission medium.

[0046] 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 that is configured to communicate signals with other control functions hosted by CU 110. 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 embodiments, CU 110 may be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units may communicate bi-directionally with the CU-CP units 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.

[0047] 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 the Radio Link Control (RLC) layer, 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 partially based on a functional split (such as those defined by 3GPP). In some aspects, DU 130 may further 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 the control functions hosted by CU 110.

[0048] Lower layer functionality may be implemented by one or more RUs 140. In some deployments, the RUs 140 controlled by the DU 130 may correspond to logical nodes that host 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, at least in part based on a functional split (such as a lower layer functional split). In such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communication with one or more UEs 104. In some embodiments, the real-time aspects and non-real-time aspects of the control plane and user plane communication 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 CU 110 in a cloud-based RAN architecture (such as a vRAN architecture).

[0049] The SMO framework 105 may be configured to support the deployment and provisioning of RANs for both 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 the O1 interface). For virtualized network elements, the SMO framework 105 may be configured to interact with a cloud computing platform (such as the 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 the O2 interface). Such virtualized network elements may include, but are not limited to, the CU 110, DU 130, RU 140, and near RT RIC 125. In some embodiments, the SMO framework 105 may communicate with hardware aspects of the 4G RAN, such as the Open eNB (O-eNB) 111, via the O1 interface. Additionally, in some embodiments, 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.

[0050] The non-RT RIC 115 can 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 can be coupled to or communicate with the near-RT RIC 125 (such as via the A1 interface). The near-RT RIC 125 can 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 the E2 interface) that connects one or more CUs 110, one or more DUs 130, or both, and the O-eNB to the near-RT RIC 125.

[0051] In some embodiments, to generate an AI / ML model to be deployed in the near-RT RIC 125, the non-RT RIC 115 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 125 and can be received from non-network data sources or from network functions at the SMO framework 105 or at the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 can monitor long-term trends and patterns in performance and employ an AI / ML model to perform corrective actions via the SMO framework 105 (such as via reconfiguration of O1) or via creation of RAN management policies (such as A1 policies).

[0052] At least one of CU 110, DU 130, and RU 140 may be referred to as base station 102. Thus, base station 102 may include one or more of CU 110, DU 130, and RU 140 (each component is indicated by a dashed line to indicate that each component may or may not be included in base station 102). Base station 102 provides an access point to core network 120 for UE 104. Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). 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. The heterogeneous network may also include a home evolved Node B (eNB) (HeNB) that 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 an uplink (UL) (also referred to as a reverse link) transmission from UE 104 to RU 140 and / or a downlink (DL) (also referred to as a 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 over one or more carriers. For each carrier allocated in carrier aggregation with a total of up to Yx MHz (x component carriers) for transmission in each direction, base station 102 / UE 104 may use a spectrum with a bandwidth of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.). 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 than for 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 carriers may be referred to as secondary cells (SCells).

[0053] Certain UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 may use DL / UL wireless wide area network (WWAN) spectrum. 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 various 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.

[0054] The wireless communication system may also include a Wi-Fi AP 150 that communicates with the UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, e.g., in an unlicensed spectrum such as the 5 GHz unlicensed spectrum. When communicating in an unlicensed spectrum, the UE 104 / AP 150 may perform a Clear Channel Assessment (CCA) before communication to determine whether the channel is available.

[0055] The electromagnetic spectrum is generally subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as Frequency Range Designation FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Although a part of FR1 is greater than 6 GHz, in various documents and articles, FR1 is generally (interchangeably) referred to as the "sub-6 GHz" band. Regarding FR2, a similar naming issue sometimes occurs, which is generally (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 by the International Telecommunication Union (ITU) as the "millimeter wave" band.

[0056] The 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 may inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to the mid-band frequencies. In addition, higher bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as Frequency Range Designation FR2-2 (52.6 GHz - 71 GHz), FR4 (71 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher bands falls within the EHF band.

[0057] Considering the above aspects, unless otherwise specifically stated, if the term "sub-6 GHz" etc. is used in this document, it may broadly represent frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, if the term "millimeter wave" etc. is used in this document, it may broadly represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR2-2, and / or FR5, or can be within the EHF band.

[0058] Base station 102 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. Base station 102 may transmit beamformed signal 182 to UE 104 in one or more transmission directions. UE 104 may receive the beamformed signal from base station 102 in one or more reception directions. UE 104 may also transmit beamformed signal 184 to base station 102 in one or more transmission directions. Base station 102 may receive the beamformed signal from UE 104 in one or more reception directions. Base station 102 / UE 104 may perform beam training to determine the optimal reception direction and transmission direction for each of base station 102 / UE 104. The transmission direction and reception direction of base station 102 may be the same or may not be the same. The transmission direction and reception direction of UE 104 may be the same or may not be the same.

[0059] Base station 102 may include and / or be referred to as a gNB, Node B, eNB, access point, base station transceiver, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transmission reception point (TRP), network node, network entity, network equipment, or some other suitable term. Base station 102 may be implemented as an integrated access and backhaul (IAB) node, relay node, sidelink node, a convergent (monolithic) base station with a baseband unit (BBU) (including CU and DU) and RU, or as a disaggregated base station including one or more of CU, DU, and / or RU. A set of base stations including disaggregated base stations and / or convergent base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0060] 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 a control node that processes signaling between the UE 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 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, one or more Location Servers 168 may include one or more location / locationing servers, which may include one or more of the GMLC 165, LMF 166, a Position Determination Entity (PDE), a Serving Mobile Location Center (SMLC), a Mobile Positioning Center (MPC), etc. The GMLC 165 and LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE location information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to calculate the location of the UE 104. The NG-RAN may utilize one or more positioning methods to determine the location of the UE 104. Positioning the UE 104 may involve signal measurements, location estimation, and speed calculation based on these measurements. The signal measurements may be performed by the UE 104 and / or the serving base station 102. The measured signals may be based on a Satellite Positioning System (SPS) 170 (e.g., a Global Navigation Satellite System (GNSS), a Global Positioning System (GPS), a Non-Terrestrial Network (NTN), or one or more of other satellite positioning / location systems), an LTE signal, a Wireless Local Area Network (WLAN) signal, a Bluetooth signal, 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, an NR signal (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.

[0061] Examples of the UE 104 include cellular phones, smart phones, Session Initiation Protocol (SIP) phones, laptop computers, 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, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other device with similar functionality. Some of the UEs in the UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). The UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, cell phone, user agent, mobile client, client, or some other suitable term. In some scenarios, the term UE may also apply to one or more accessory devices, such as in a device cluster arrangement. One or more of these devices may access the network jointly and / or separately access the network.

[0062] Refer again to Figure 1, in some aspects, the UE 104 may have an LP-PRS measurement component 198 configured to receive auxiliary data via a first radio component, where the auxiliary data may include the configuration of an LP-PRS set. The LP-PRS measurement component 198 may receive the LP-PRS set via a second radio component. The second radio component may have lower power consumption than the first radio component. The LP-PRS measurement component 198 may measure the LP-PRS set based on the configuration of the LP-PRS set. In some aspects, the base station 102 may have an LP-PRS transmission component 197 configured to transmit the LP-PRS set to the second radio component at the UE. The LP-PRS transmission component 197 may transmit an LP-WUS to the second radio component at the UE, where the LP-WUS may include an indication to measure the LP-PRS set. The second radio component may have lower power consumption than the first radio component at the UE. In some aspects, the base station 102 may have an LP-PRS configuration component 199 configured to transmit auxiliary data to the first radio component at the UE, where the auxiliary data may include the configuration of a first set of LP-PRSs. The LP-PRS configuration component 199 may receive a measurement report based on the measurement of the LP-PRS set from the UE from the first radio component at the UE. The first radio component may include a main radio component (MR), and the second radio component may include an LP wake-up receiver (LP-WUR). Although the following description may focus on positioning using a wireless device having an LP-WUR and a main radio component (MR), the concepts described herein may apply 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 domains, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0063] Figure 2A FIG. 200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG. 230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG. 250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG. 280 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), the subframes within that set of subcarriers are dedicated to DL or UL), or may be time division duplex (TDD) (where, for a particular set of subcarriers (carrier system bandwidth), the subframes within that set of subcarriers are dedicated to both DL and UL). In Figure 2A, Figure 2C In the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (where most are DL), where D is DL, U is UL, and F is flexibly usable between DL / UL, and subframe 3 is configured with slot format 1 (where all are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0 - 61. Slot formats 0 and 1 are all-DL and all-UL respectively. The other slot formats 2 - 61 include a mixture of DL, UL, and flexible symbols. The UE is configured with the slot format by the received slot format indicator (SFI) (configured dynamically by DL control information (DCI) or semi-statically / statically by radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0064] Figures 2A to 2D The frame structure is illustrated, and aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and / or different channels. One frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe can include one or more slots. The subframe can also include mini-slots, which can include 7, 4, or 2 symbols. Each slot can include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each slot can include 14 symbols, and for extended CP, each slot can include 12 symbols. The symbols on the DL can be cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) symbols. The symbols on the UL can be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (for power-constrained scenarios; limited to single-stream transmission). The number of slots within a subframe is based on the CP and the parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration can be scaled with 1 / SCS.

[0065]

[0066] Table 1: Parameter set, SCS, and CP

[0067] For normal CP (14 symbols / slot), the 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 slots / subframe. The subcarrier spacing can be equal to 2 μ*15 kHz, where μ is a parameter set from 0 to 4. Thus, the subcarrier spacing for parameter set μ = 0 is 15 kHz, and the subcarrier spacing for parameter set μ = 4 is 240 kHz. The symbol length / duration is negatively correlated with the subcarrier spacing. Figures 2A to 2D An example of parameter set μ = 2 with normal CP having 14 symbols per time slot and 4 time slots per subframe is provided. The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 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).

[0068] A resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also known as a physical RB (PRB)) that extends over 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.

[0069] As Figure 2A illustrated, some of the REs carry reference (pilot) signals (RSs) for the UE. The RSs can include demodulation RSs (DM-RSs) (designated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RSs) for channel estimation at the UE. The RSs can also include beam measurement RSs (BRSs), beam refinement RSs (BRRSs), and phase tracking RSs (PT-RSs).

[0070] Figure 2BIllustrates examples 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), where each CCE includes six Resource Element Groups (REGs), and each REG includes 12 consecutive Resource Elements (REs) in the OFDM symbols of an RB. The PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during a PDCCH monitoring occasion on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) can be in symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and the physical layer identity. The Secondary Synchronization Signal (SSS) can be in symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the 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 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 number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not sent via the PBCH (such as System Information Blocks (SIBs)), and paging messages.

[0071] As Figure 2C Illustrated, some of the REs carry DM-RS (denoted as R for a specific configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the previous one or two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS can be transmitted in different configurations. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of the subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the teeth of the comb. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0072] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at the position indicated in one configuration. The PUCCH carries uplink control information (UCI), such as a scheduling request, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and a 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.

[0073] Figure 3 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 functionality. Layer 3 includes the radio resource control (RRC) layer, and layer 2 includes the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, and the media access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with the broadcast 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 functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and re-ordering of RLC data PDUs; and MAC layer functionality associated with the 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 via HARQ, priority handling, and logical channel prioritization.

[0074] 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 the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The Tx processor 316 processes the mapping to the signal constellation diagram 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 encoded and modulated symbols may then be split into parallel streams. Subsequently, each stream may be mapped to OFDM subcarriers, multiplexed with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then combined together using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain OFDM symbol stream. The OFDM stream is precoded in space to generate multiple spatial streams. Channel estimates from the channel estimator 374 may be used to determine the encoding and modulation schemes, as well as for spatial processing. The channel estimates may be derived from reference signals transmitted by the UE 350 and / or channel state feedback. Then, each spatial stream may be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier with the corresponding spatial stream for transmission.

[0075] At the UE 350, each receiver 354Rx receives signals via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the 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 into a single OFDM symbol stream by the Rx processor 356. Then, the Rx processor 356 uses a fast Fourier transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency-domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier 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 the channel estimates computed by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals 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.

[0076] The controller / processor 359 may be associated with a memory 360 that stores program code 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 the ACK and / or NACK protocols to support HARQ operations.

[0077] Similar to the functionality described in connection with DL transmission performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction via 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 the mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel prioritization.

[0078] Channel estimates derived by the channel estimator 358 from reference signals or feedback transmitted by the base station 310 may be used by the Tx processor 368 to select appropriate decoding 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 a separate transmitter 354Tx. Each transmitter 354Tx modulates an RF carrier with the corresponding spatial stream for transmission.

[0079] UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver functionality at the UE 350. Each receiver 318Rx receives signals via its corresponding antenna 320. Each receiver 318Rx recovers the information modulated onto the RF carrier and provides this information to the Rx processor 370.

[0080] The controller / processor 375 may be associated with a memory 376 that stores program code 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 the ACK and / or NACK protocols to support HARQ operations.

[0081] At least one of Tx processor 368, Rx processor 356, and controller / processor 359 may be configured to perform aspects associated with Figure 1 LP-PRS measurement component 198 of

[0082] At least one of Tx processor 316, Rx processor 370, and controller / processor 375 may be configured to perform aspects associated with Figure 1 LP-PRS transmission component 197 of

[0083] At least one of Tx processor 316, Rx processor 370, and controller / processor 375 may be configured to perform aspects associated with Figure 1 LP-PRS configuration component 199 of

[0084] Figure 4 FIG. 400 is a diagram illustrating an example of UE positioning based on reference signal measurement. UE 404 may transmit UL-SRS 412 at time T SRS_TX and receive downlink positioning reference signal (PRS) (DL-PRS) 410 at time T PRS_RX . TRP 406 may receive UL-SRS 412 at time T SRS_RX and transmit DL-PRS 410 at time T PRS_TX . 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 RTT 414 based on ||T SRS_RX –T PRS_TX |–|T SRS_TX –T PRS_RX ||. Thus, multi-RTT positioning may utilize UE Rx-Tx time difference measurements of downlink signals received from multiple TRPs 402, 406 and measured by UE 404 (i.e., |T SRS_TX –T PRS_RX |) and downlink positioning reference signal received power (RSRP) (DL-PRS-RSRP), as well as measured TRP Rx-Tx time difference measurements of uplink signals transmitted from UE 404 at multiple TRPs 402, 406 (i.e., |T SRS_RX –T PRS_TX(and UL-SRS-RSRP). The UE 404 uses the assistance data received from the positioning server to measure the UE Rx-Tx time difference measurement (and the DL-PRS-RSRP of the received signal), and the TRPs 402, 406 use the assistance data received from the positioning server to measure the gNB Rx-Tx time difference measurement (and the UL-SRS-RSRP of the received signal). These measurements can be used at the positioning server or the UE 404 to determine the RTT, which is used to estimate the location of the UE 404. Other methods for determining the RTT are possible, such as using DL-TDOA and / or UL-TDOA measurements.

[0085] DL-AoD positioning can utilize the measured DL-PRS-RSRP of the downlink signals received at the UE 404 from multiple TRPs 402, 406. The UE 404 uses the assistance data received from the positioning server to measure the DL-PRS-RSRP of the received signal, and the resulting measurement, together with the azimuth of departure (A-AoD), zenith angle of departure (Z-AoD), and other configuration information, is used to position the UE 404 relative to the neighboring TRPs 402, 406.

[0086] DL-TDOA positioning can utilize the DL reference signal time difference (RSTD) (and DL-PRS-RSRP) of the downlink signals received at the UE 404 from multiple TRPs 402, 406. The UE 404 uses the assistance data received from the positioning server to measure the DL RSTD (and DL-PRS-RSRP) of the received signal, and the resulting measurement, together with other configuration information, is used to position the UE 404 relative to the neighboring TRPs 402, 406.

[0087] UL-TDOA positioning can utilize the UL relative time of arrival (RTOA) (and UL-SRS-RSRP) of the uplink signals transmitted from the UE 404 at multiple TRPs 402, 406. The TRPs 402, 406 use the assistance data received from the positioning server to measure the UL-RTOA (and UL-SRS-RSRP) of the received signal, and the resulting measurement, together with other configuration information, is used to estimate the location of the UE 404.

[0088] UL-AoA positioning can utilize the measured azimuth of arrival (A-AoA) and zenith angle of arrival (Z-AoA) of the uplink signals transmitted from the UE 404 at multiple TRPs 402, 406. The TRPs 402, 406 use the assistance data received from the positioning server to measure the A-AoA and Z-AoA of the received signal, and the resulting measurement, together with other configuration information, is used to estimate the location of the UE 404.

[0089] Additional positioning methods can be used to estimate the location of UE 404, such as UE-side UL-AoD and / or DL-AoA. Note that data / measurements from various techniques can be combined in various ways to increase accuracy, determine and / or enhance certainty, supplement / complete measurements, and / or replace / provide missing information.

[0090] Figure 5A FIG. 500 illustrates UE 502 communicating wirelessly with TRP 504 and TRP 505. UE 502 has a radio component 506 in a closed or sleep mode (i.e., deep sleep mode), and a radio component 508 in an on or active mode. The radio component 506 can be, for example, the main radio component (MR) of UE 502. The radio component 508 can be, for example, a low-power (LP) wake-up radio component (LP-WUR) of UE 502. The radio component 508 can be a companion receiver that monitors an LP wake-up signal (LP-WUS). The radio component 508 can have lower power consumption than the radio component 506. If UE 502 is not scheduled to transmit or receive data during a certain period of time, UE 502 can be configured to switch the radio component 506 to the closed or sleep mode during that period. In other words, UE 502 can be configured to switch the radio component 506 to the sleep mode unless there is something to transmit. The radio component 508 can be in the active mode, monitoring the reception of signals such as LP-WUS. The radio component 506 and the radio component 508 can share an antenna 510 to communicate with one or more network nodes (such as TRP 504 via communication 512 or TRP 505 via communication 513). UE 502 can be configured to monitor communication 512 from TRP 505 or communication 513 from TRP 504 to monitor signals such as LP-WUS. In some aspects, the radio component 506 and the radio component 508 can use separate antennas to communicate with one or more network nodes. Although UE 502 is shown as having two radio components, in other aspects, the UE can have more than two radio components, such as three radio components, four radio components, or more radio components with similar power consumption levels or with different power consumption levels. The radio component 506 can also be referred to as a high-power radio component (HPR). The radio component 508 can be referred to as a low-power radio component (LPR). The radio component 506 can be configured to receive and measure an orthogonal frequency division multiplexing (OFDM) waveform. The radio component 508 can be configured to receive and measure an on-off keying (OOK) waveform or an amplitude-shift keying-based modulation waveform. The radio component 508 is not configured to receive and measure an OFDM waveform.

[0091] Figure 5B is an illustration Figure 5B of UE 502 in FIG. 550, where radio component 506 is switched to an on or active mode and radio component 508 is switched to an off or inactive mode or a sleep mode. If UE 502 is scheduled to transmit or receive data during a certain time period, UE 502 may be configured to switch radio component 506 to an on mode or an active mode during that time period. In other words, UE 502 may be configured to switch radio component 506 to an active mode when there is something to transmit. In some aspects, TRP 504 may send communication 512 to radio component 508 of UE 502, and the communication includes on-demand LP-WUS. In some aspects, TRP 505 may send communication 513 to radio component 508 of UE 502, and the communication includes on-demand LP-WUS. In response, UE 502 may switch radio component 506 from Figure 5A the inactive mode in Figure 5B to the active mode in

[0092] When radio component 506 is in the active mode, UE 502 may send and receive data with TRP 504 via radio component 506 using communication 552, or may send and receive data with TRP 505 via radio component 506 using communication 513.

[0093] Figure 6600 is a diagram illustrating an example LP-RS 602, which may be a waveform based on on-off keying (OOK). The baseline LP-RS 602 may be transmitted by a transmitting device such as Figure 5A and Figure 5B The TRP 504 or TRP 505 in LP-RS 602 is constructed by repeating the mother signal S on consecutive symbols based on the binary index sequence and the Manchester decoding scheme. LP-RS 602 may include four bits: bit 610, bit 620, bit 630, and bit 640. Bit 610 and bit 620 both convey a zero value. Bit 630 and bit 640 both convey a one value.

[0094] When the corresponding index is one, the symbol may start with S (on signal) followed by zero (off signal). When the corresponding index is zero, the symbol may start with zero (off signal) followed by S (on signal). The mother signal S may be generated by an inverse fast Fourier transform (IFFT) output of a Zadoff-Chu sequence mapped to multiple subcarriers. The sequence length may be used to define the signal bandwidth of LP-RS 602. When the LP-WUR uses an envelope detector to detect the LP-RS, the mother signal S may not be used to signal the UE. In some aspects, the binary index sequence may have good autocorrelation characteristics and cross-correlation characteristics. For example, the binary index sequence may have a Gold sequence and may provide a cell ID.

[0095] Although the LP-RS 602 may be based on an OOK waveform as shown, the LP-RS may be based on any waveform of low complexity, such as a modulation waveform based on amplitude shift keying.

[0096] 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 location management function (LMF) 708. Figure 1 UE 104 in or Figure 5A and Figure 5B 700 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 a radio resource control (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 RRC connected state. The UE 702 may have an HPR (such as Figure 5A and Figure 5B ), the HPR may measure DL-PRS from a network node, such as a DL-PRS set 726 from a serving network node 704 or a DL-PRS set 728 from a neighboring network node 706.

[0097] The auxiliary information controller 710 may be configured to communicate with the serving network node 704, the neighbor network node 706, and the LMF 708. The auxiliary information controller 710 may be, for example Figure 1 the core network 120, the near RT RIC 125, or the non-RT RIC 115 in. When the UE 702 is in the RRC inactive mode, the auxiliary information controller 710 may provide auxiliary data to support downlink (DL) positioning. In one aspect, the LMF 708 may 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 may send the LPP 712 to the UE 702. The UE 702 may receive the LPP 712 from the LMF 708. The LPP may include auxiliary data that includes the configuration of the DL-PRS 726 or a set of DL-PRSs 728. In other aspects, the serving network node 704 may 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 may send the posSIB 714 to the UE 702. The UE 702 may receive the posSIB from the serving network node.

[0098] At 716, the UE 702 may switch to the RRC inactive mode. The UE 702 may have been pre-configured to use the LPP 712 and / or the posSIB 714 for DL positioning. At 730, the UE 702 may perform positioning measurements based on the received set of DL-PRSs. The serving network node 704 may send a set of DL-PRSs 726 that can be used for positioning. The neighbor network node 706 may send a set of DL-PRSs 728 that can be used for positioning. The UE 702 may have an HPR configured to be in the active mode to receive the set of DL-PRSs. The UE 702 may receive the set of DL-PRSs 726 from the serving network node 704. The UE 702 may receive the set of DL-PRSs 728 from the neighbor network node 706. Although one neighbor network node is shown in the communication flow diagram 700 in Figure 7 in other aspects, the UE 702 may receive DL-PRSs from multiple neighbor network nodes.

[0099] At 730, the UE 702 may measure the DL-PRS set. The UE 702 may measure the DL-PRS set 726 received from the serving network node 704. The UE 702 may measure the DL-PRS set 728 received from the neighbor network node 706. In some aspects, the UE 702 may send a 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 HPR. In some aspects, the UE 702 may send a location service (LCS) event report 734 to the LMF 708. The LCS event report 734 may be based on the measurements made at 730. The UE 702 may send the LCS event report 734 from its HPR. In summary, the UE 702 may send the measurements it makes at 730 without transitioning to the RRC connected state, thus remaining in the RRC inactive mode while sending the UL-SDT 732 and / or the LCS event report 734.

[0100] Although the UE 702 may be configured to use its HPR to periodically measure all DL-PRSs to frequently update the priorities for measuring DL-PRSs, using the HPR so frequently may consume a large amount of power. In some aspects, the UE 702 may be configured to align the DL-PRS set 726 and the DL-PRS set 728 with the paging discontinuous reception (DRX) cycle of the UE 702, which may allow the UE 702 to put its HPR to sleep and periodically switch to the active mode to receive the DL-PRS. However, the network may send the DL-PRS to multiple UEs in the cell, and the paging DRX cycle may be specific to each UE. Aligning the DL-PRS set 726 and the DL-PRS set 728 with the paging DRX cycle of the UE 702 may prevent other UEs from receiving the DL-PRS that is not aligned with the DRX cycle of the UE 702. 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 idle mode. In some aspects, the UE 702 may be configured to use the LPR instead of its HPR to monitor the DL-PRS set. However, some LPRs may not be configured to receive the DL-PRS set. For example, the serving network node 704 may use the OFDM waveform to send the DL-PRS set 726, but the LPR of the UE 702 may have a lower complexity decoder that does not support the OFDM waveform (e.g., based on an envelope detector).

[0101] Therefore, it may be beneficial to improve the positioning technique using LPR to save power at the UE, for example, by using an LP-RS design that can be received and measured by an LPR (e.g., a low-complexity LP-WUR). The LP-RS can be constructed based on a waveform of OOK (e.g., the LP-RS 602 in Figure 6 or based on another low-complexity waveform (e.g., a modulation waveform based on amplitude shift keying). Such LP-RS can be monitored by an LPR such as an LP-WUR for positioning measurements, thereby reducing UE power consumption. In one aspect, a second network node may send a configuration of an LP-PRS set for the UE. The UE may receive the configuration of the LP-PRS set. A first network node may send the LP-PRS set to the LP-WUR of the UE for the UE. The UE may use the LP-WUR to receive the LP-PRS set. The first network node may send an LP-WUS that includes an indication of measuring the LP-PRS set. The UE may receive the LP-WUS that includes an indication of measuring the LP-PRS set. The UE may measure the LP-PRS set based on the configuration of the LP-PRS set and the indication of measuring the LP-PRS set.

[0102] Figure 8 is a communication flow diagram 800 of a UE 802 (such as Figure 1 the UE 104 in Figure 5A and Figure 5B the UE 502 in Figure 5A and Figure 5B ), which is configured to communicate with a serving network node 804, one or more neighbor network nodes (such as a neighbor network node 806), and an LMF 808. In some aspects, the UE 802 may be configured to perform positioning measurements when the UE 802 is in the RRC inactive state. By configuring the UE 802 to perform positioning measurements when the UE 802 is in the RRC inactive state, the UE 802 can perform positioning measurements without switching to the RRC connected mode or the RRC connected state. The UE 802 may have an HPR (such as Figure 5A and Figure 5B the radio component 506 in

[0103] The auxiliary information controller 810 may be configured to communicate with the serving network node 804, the neighbor network node 806, and the LMF 808. The auxiliary information controller 810 may be, for example, Figure 1The core network 120, the near RT RIC 125, or the non-RT RIC 115 in. When the UE 802 is in the RRC inactive mode, the auxiliary information controller 810 may provide auxiliary data to support DL positioning using LP-RS (such as LP-PRS). In one aspect, the LMF 808 may use the auxiliary information controller 810 to generate an LPP message to configure the UE 802 for DL positioning (e.g., positioning measurements based on LP-PRS). The LPP message may include, for example, a NAS message. The LMF 808 may send the LPP 812 to the UE 802. The UE 802 may receive the LPP 812 from the LMF 808. The LPP 812 may include auxiliary data for positioning measurements. The auxiliary data may include the configuration of LP-PRS, such as the LP-PRS set 820 from the serving network node 804 and / or the LP-PRS set 822 from the neighbor network node 806. Each of the LP-PRS set 820 and the LP-PRS set 822 may be considered a subset of the LP-PRS set configured by the auxiliary data. In other aspects, the serving network node 804 may 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 may send the posSIB 814 to the UE 802. The UE 802 may receive the posSIB from the serving network node. The posSIB 814 may include auxiliary data for positioning measurements. The positioning measurements may include the configuration of one or more LP-PRS sets, such as the LP-PRS set 820 from the serving network node 804 and / or the LP-PRS set 822 from the neighbor network node 806. The positioning measurements based on LP-PRS may be applied to enhanced cell ID (E-CID). The positioning measurements based on LP-PRS may be applied to the positioning method based on the DL angle of departure (DL-AoD).

[0104] At 816, the UE 802 may switch to the RRC inactive mode. The UE 802 may have been pre-configured for DL positioning using the LPP 812 and / or the posSIB 814. At 818, the UE 802 may switch its HPR to the off mode or the sleep mode, and may switch its LPR to the on mode or the active mode. In some aspects, the UE 802 may be configured to always keep its LPR in the active mode regardless of whether it is in an RRC connection or a non-RRC connection, because the LPR may not consume too much power. The serving network node 804 may send the LP PRS set 820 to the UE 802. The UE 802 may receive the LP-PRS set 820 from the serving network node 804. The neighbor network node 806 may send the LP PRS set 822 to the UE 802. The UE 802 may receive the LP-PRS set 822 from the neighbor network node 806. Although inFigure 8 A neighboring network node is shown, but multiple neighboring network nodes may be configured to send LP-PRS sets to UE 802. UE 802 may have an LPR configured to be in an active mode to receive LP-PRS sets.

[0105] In some aspects, wireless devices that send LP-PRS sets to UE 802 (such as serving network node 804 that sends LP-PRS set 820 and neighboring network node 806 that sends LP-PRS set 822) may be configured to send LP-PRS sets based on a minimum signal duration. The minimum signal duration may be, for example, at least 40 milliseconds (ms). In other words, the transmitting device may support a long enough signal duration so that even for a low SNR of the LPR of UE 802, single detection can be performed to reduce positioning latency. The transmitting device may be configured to use a long signal duration in combination with a large periodicity to ensure that the overhead of LP-PRS does not exceed a threshold, such as more than 200 ms per second.

[0106] In some aspects, the transmitting device (such as serving network node 804 that sends LP-PRS set 820 and neighboring network node 806 that sends LP-PRS set 822) may be configured to use long sequences or short sequences extended by covering codes. In one aspect, the transmitting device may use a long signal duration. The length of the LP-PRS that the transmitting device may use is equal to the total number of symbols in the duration of the LP-PRS. In another aspect, the transmitting device may use a short signal LP-PRS sequence with a covering code. The transmitting device may split the LP-PRS time-domain signal into multiple segments (e.g., N segments, or repeated copies), where the sequence of the i-th segment may be defined by i d(n) = c(n) ⊕ b(i), where b(i) may be a covering code, c(n) may be a short LP-PRS sequence, and ⊕ may represent binary addition. In some aspects, the transmitting device may design a binary covering code to achieve combination, so as to cumulatively obtain relevant results across repetitions in an explicit manner. In some aspects, the covering codes may all be zero values, which may result in a simple repetition of the short sequences used in each segment.

[0107] At 830, the UE 802 may perform positioning measurements based on the received LP-PRS set. The UE 802 may measure the LP-PRS set 820 received from the serving network node 804. The UE 802 may measure the LP-PRS set 822 received from the neighbor network node 806. The measurements of the LP-PRS set 820 and / or the LP-PRS set 822 may be based on the configuration in the assistance data, such as the resources allocated to the LP-PRS indicated by the configuration or the scheduling of the LP-PRS indicated by the configuration. In some aspects, the UE 802 may calculate the RSRP of these LP-PRS sets based on measuring the LP-PRS set 820 and / or the LP-PRS set 822. In some aspects, the UE 802 may calculate the reference signal strength indicator (RSSI) of these LP-PRS sets based on measuring the LP-PRS set 820 and / or the LP-PRS set 822. The UE 802 may generate a measurement report based on the calculated RSRP and / or the calculated RSSI of the LP-PRS set.

[0108] At 831, the UE may switch its HPR to the on or active mode and may switch its LPR to the off or inactive mode. In some aspects, the UE 802 may send the measurement report as a UL-SDT 832 to the serving network node 804. The UE 802 may send the UL-SDT 832 from its HPR. In some aspects, the UE 802 may send the measurement report as an LCS event report 834 to the LMF 808. The LCS event report 834 may be based on the measurements performed at 830. The UE 802 may send the LCS event report 834 from its HPR. In summary, the UE 802 may send the measurements it performed at 830 without transitioning to the RRC connected state, thus remaining in the RRC inactive mode and saving power by keeping its HPR in the sleep mode while receiving and measuring the LP-PRS set. The UE 802 may switch its HPR to the active mode based on the measurements of the LP PRS set to send the UL-SDT 832 and / or the LCS event report 834. The UL-SDT 832 may include multiple transmissions, such as one transmission having a measurement report for the LP-PRS set 820 and another transmission having a measurement report for the LP-PRS set 822. The LCS event report 834 may include multiple transmissions, such as one transmission having a measurement report for the LP-PRS set 820 and another transmission having a measurement report for the LP-PRS set 822.

[0109] The LP-PRS set can be configured to be periodic, semi-persistent, or aperiodic. In some aspects, LP-WUS can be used to trigger positioning measurements of the LP-PRS, or LP-WUS can be used to indicate the presence of the LP-PRS. For example, the serving network node 804 can send LP-WUS to the UE 802 before sending the LP-PRS set 820, and the neighbor network node 806 can send LP-WUS to the UE 802 before sending the LP-PRS set 822. In other words, the LP-PRS set 820 in the communication flowchart 800 can be considered to include LP-WUS followed by the LP-PRS set, and / or the LP-PRS set 822 can be considered to include LP-WUS followed by the LP-PRS set. In some aspects, in response to receiving LP-WUS indicating the presence of the LP-PRS, the UE 802 can reconfigure one or more components of its LPR for receiving and / or decoding the LP-PRS. In one aspect, the UE 802 can reconfigure the analog-to-digital converter (ADC) of its LPR to use more bits to receive or measure the LP-PRS set 820 or the LP-PRS set 822. For example, the UE 802 can reconfigure its ADC from single-bit operation to multi-bit operation. The UE 802 can reconfigure one or more components in response to receiving LP-WUS indicating the LP-PRS set.

[0110] The LP-PRS set can be configured with a reduced signal bandwidth to support low signal-to-noise ratio radio components (SNR). Figure 9A FIG. 900 is a diagram illustrating an example of LP-PRS with a reduced signal bandwidth.

[0111] Figure 9A FIG. 900 is a diagram illustrating an example of LP-RS with a normal signal bandwidth. The signal 902 can span the entire bandwidth of the LPR of the UE (such as Figure 5A and Figure 5B the radio component 508 therein). The signal 902 can use N resource blocks (RBs) that span the entire bandwidth that the LPR of the UE can receive and measure. The signal 902 can represent LP-WUS sent from the network node to the UE, and the LP-WUS can use the entire signal bandwidth that the LPR of the UE may be able to receive.

[0112] Figure 9B is an illustration related to Figure 9AIllustration 910 of an example of an LP-RS having a reduced contiguous signal bandwidth compared to illustration 900 in []. Signal 914 may not use the RBs of portion 912 or portion 916 of the LPR bandwidth. Signal 914 may use N / 2 RBs of the LPR bandwidth. The smaller bandwidth allows the LPR to process signal 914 at a lower sampling rate. This may reduce the complexity at the UE and may also reduce the power consumption at the UE while maintaining good detection performance. In some aspects, a transmitting network node (such as Figure 8 the serving network node 804 or the neighbor network node 806 in []) may apply power boosting to the signal with the smaller bandwidth to ensure that the total received signal power of signal 914 does not decrease by a threshold amount compared to signal 902. Signal 914 may represent an LP-PRS transmitted from a network node to a UE. By using a smaller signal bandwidth for the LP-PRS (e.g., signal 914 in illustration 910) than for the LP-WUS (e.g., signal 902 in illustration 900), the UE may use a smaller measurement complexity to receive and / or measure the LP-PRS than for the LP-WUS. By using a smaller signal bandwidth for the LP-PRS than for the LP-WUS, the network node may transmit the LP-PRS at a higher power level than the LP-WUS, which may increase the SNR of the LP-PRS compared to the LP-WUS.

[0113] Figure 9C Illustration 920 is an example of an LP-RS having a first portion 922 and a second portion 926 in a reduced non-contiguous signal bandwidth. The LP-RS may not use the RBs of portion 924 of the LPR bandwidth. The first portion 922 of the signal and the second portion 926 of the signal may use a total of N / 2 RBs, similar to Figure 9B signal 914 in illustration 910 in []. Similarly, the smaller bandwidth may allow the LPR to process the LP-RS of illustration 920 at a lower sampling rate than Figure 9A signal 902 in illustration 900 in []. The non-contiguous bandwidth may provide better frequency diversity. Although the signal in illustration 920 is shown as being split into two portions, in other aspects, the signal may be split into more than two portions, such as three, four, or more portions. The UE may use additional processing overhead to separate out the narrowband components of the signal and properly recombine them before an envelope detector. In some aspects, the UE may recombine the first portion 922 of the signal and the second portion 926 of the signal by concatenating RBs. The signal combining the first portion 922 of the signal and the second portion 926 of the signal may represent an LP-PRS transmitted from a network node to a UE.

[0114] In some aspects, an LP-PRS set may be configured with a repeating pattern to improve performance and SNR.

[0115] Figure 10A FIG. 1000 is an illustration showing an example of a repeating pattern of LP-PRS1002. LP-PRS1002 can be sequentially mapped to K symbols numbered from 1 to K. LP-PRS1002 can be repeated based on an offset 1004. LP-PRS1002 can be repeated N times. The number of symbols K, the number of repetitions N, and the offset 1004 can each be configured by a network entity (such as Figure 8 the LMF 808 or the auxiliary information controller 810 in FIG. 808). In some aspects, the network entity can improve performance by allowing coherent combination across repeated LP-PRSs.

[0116] Figure 10B FIG. 1050 is an illustration showing an example of another repeating pattern of LP-PRS1052. LP-PRS1052 can map the number of repetitions N of each symbol of the LP-PRS. After mapping one modulation symbol, the symbol can be repeated N times to complete a set of symbols, such as the first set of symbols 1060. Then, the transmitting node can continue to map other modulation symbols and repeat the symbol N times to complete the symbol. For example, after repeating the first modulation symbol N times to generate the first set of symbols 1060, the transmitting node can repeat the second modulation symbol N times to generate the second set of symbols 1070 until all K symbols have been generated. LP-PRS1052 can have better performance than Figure 10A the LP-PRS1002 in FIG. 808 because LP-PRS1052 may have a relaxed specification for memory access if the demodulation result is stored in an external memory. The repeating pattern of LP-PRS1052 can also be referred to as a non-sequential set of symbols because the second symbol does not immediately follow the first symbol. Instead, the first symbol is repeated N times as the first set of symbols 1060 until the second set of symbols is repeated N times as the second set of symbols 1070.

[0117] Figure 11 FIG. 1100 is a flowchart of a wireless communication method. The method can be performed by a UE (e.g., UE 104, UE 350, UE404, UE 502, UE 702, UE 802; apparatus 1804). At 1102, the UE can receive auxiliary data via a first radio component, and the auxiliary data can include the configuration of an LP-PRS set. For example, 1102 can be performed by Figure 8 the UE 802 in FIG. 808, which can receive the LPP 812 including the auxiliary data via the HPR of the UE 802, and the auxiliary data includes the configuration of an LP-PRS set (such as the LP-PRS set 820 and / or the LP-PRS set 822). 1102 can also be performed by Figure 8be performed by the UE 802 therein, which may receive, via the HPR of the UE 802, the posSIB 814 that may include the auxiliary data, and the auxiliary data includes the configuration of the LP-PRS set (such as the LP-PRS set 820 and / or the LP-PRS set 822). In addition, 1102 may be performed by Figure 18 the component 198 therein.

[0118] At 1104, the UE may receive the LP-PRS set via a second radio component, where the second radio component may have lower power consumption than the first radio component. For example, 1104 may be performed by Figure 8 the UE 802 therein, which may receive the LP-PRS set 820 and / or the LP-PRS set 822 via the LPR of the UE 802. The LPR of the UE 802 may have lower power consumption than the HPR of the UE 802. In addition, 1104 may be performed by Figure 18 the component 198 therein.

[0119] At 1106, the UE may measure the LP-PRS set based on the configuration of the LP-PRS set. For example, 1106 may be performed by Figure 8 the UE 802 therein, which may measure the LP-PRS set 820 and / or the LP-PRS set 822 at 803 based on the configuration of the LP-PRS set of the auxiliary data from the LPP 812 or the posSIB 814. In addition, 1106 may be performed by Figure 18 the component 198 therein.

[0120] Figure 12 is a flowchart 1200 of a wireless communication method. The method may be performed by a UE (such as UE 104, UE 350, UE404, UE 502, UE 702, UE 802; device 1804). At 1201, the UE may receive at least one of an LPP message or a posSIB that may include the auxiliary data. For example, 1201 may be performed by Figure 8 the UE 802 therein, which may receive the LPP 812 that may include the auxiliary data from the LMF 808 or the posSIB 814 that may include the auxiliary data from the serving network node 804. In addition, 1201 may be performed by Figure 18 the component 198 therein.

[0121] At 1202, the UE may receive the auxiliary data via a first radio component, and the auxiliary data may include the configuration of the LP-PRS set. For example, 1202 may be performed by Figure 8be performed by the UE 802 in [description of the context], which may receive, via the HPR of the UE 802, LPP 812 that may include auxiliary data including the configuration of an LP-PRS set (such as LP-PRS set 820 and / or LP-PRS set 822). 1202 may also be performed by Figure 8 the UE 802 in [description of the context], which may receive, via the HPR of the UE 802, posSIB 814 that may include auxiliary data including the configuration of an LP-PRS set (such as LP-PRS set 820 and / or LP-PRS set 822). Additionally, 1202 may be performed by Figure 18 component 198 in [description of the context].

[0122] At 1203, the UE may receive an LP-WUS via a second radio component, where the LP-WUS may include an indication associated with an LP-PRS set. For example, 1203 may be performed by Figure 8 the UE 802 in [description of the context], which may receive the LP-WUS via the LPR at the UE 802, and the LP-WUS may include an indication associated with an LP-PRS set. For example, LP-PRS set 820 may include an LP-WUS followed by an LP-PRS set, and LP-PRS set 822 may include an LP-WUS followed by an LP-PRS set. Additionally, 1203 may be performed by Figure 18 component 198 in [description of the context].

[0123] At 1204, the UE may receive an LP-PRS set via a second radio component, where the second radio component may have lower power consumption than the first radio component. For example, 1204 may be performed by Figure 8 the UE 802 in [description of the context], which may receive LP-PRS set 820 and / or LP-PRS set 822 via the LPR of the UE 802. The LPR of the UE 802 may have lower power consumption than the HPR of the UE 802. Additionally, 1204 may be performed by Figure 18 component 198 in [description of the context].

[0124] At 1206, the UE may measure an LP-PRS set based on the configuration of the LP-PRS set. For example, 1206 may be performed by Figure 8 the UE 802 in [description of the context], which may measure LP-PRS set 820 and / or LP-PRS set 822 at 803 based on the configuration of the LP-PRS set of the auxiliary data from LPP 812 or posSIB 814. Additionally, 1206 may be performed by Figure 18 component 198 in [description of the context].

[0125] At 1208, the UE may receive LP-WUS using a second signal bandwidth. For example, 1208 may be performed by the UE 802 in Figure 8 , which may receive LP-WUS using a second signal bandwidth (such as the bandwidth of signal 902 of all N RBs using the LPR bandwidth in Figure 9A ). Additionally, 1208 may be performed by the component 198 in Figure 18 .

[0126] At 1210, the UE may receive a set of LP-PRS using a first signal bandwidth. The first signal bandwidth may be less than the second signal bandwidth. For example, 1210 may be performed by the UE 802 in Figure 8 , which may receive the set of LP-PRS using a first signal bandwidth (such as the bandwidth of signal 914 of N / 2 RBs using the LPR bandwidth in Figure 9B or the bandwidth of signal of N / 2 RBs using the LPR bandwidth having a first part 922 and a second part 926 in Figure 9C ). Figure 9B The bandwidth of signal 914 in Figure 9C or the bandwidth of the signal having a first part 922 and a second part 926 in Figure 9A is less than the bandwidth of signal 902 in Figure 18 . Additionally, 1210 may be performed by the component 198 in

[0127] At 1212, the UE may receive a first subset of the set of LP-PRS from a first network node via a second radio component. For example, 1212 may be performed by the UE 802 in Figure 8 , which may receive the set of LP-PRS 820 from the serving network node 804 via the LPR of the UE 802. 1212 may be performed by the UE 802 in Figure 8 , which may receive the set of LP-PRS 822 from the neighbor network node 806 via the LPR of the UE 802. Additionally, 1212 may be performed by the component 198 in Figure 18 .

[0128] At 1214, the UE may receive a second subset of the set of LP-PRS from a second network node via a second radio component. The first network node may be different from the second network node.
