CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. non-provisional patent application serial number 18 / 183,064, filed on March 13, 2023, entitled “REPEATER POWER MANAGEMENT FOR POSITIONING,” which is expressly incorporated herein by reference in its entirety. Technical Field

[0002] The present disclosure relates generally to communication systems and, more particularly, to wireless communications utilizing positioning. Background Art

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems 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), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and time division synchronous code division multiple access (TD-SCDMA).

[0004] 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 continued evolution of mobile broadband, promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., for 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 adopt these technologies. Summary of the Invention

[0027] A wireless communication network (such as a 5G NR network) can implement positioning measurements and operations for wireless devices. For example, the wireless communication network and / or wireless device can utilize measurements associated with specific signaling to determine one or more angles of arrival, power levels of transmitted / received signals, and the like for positioning operations. As an example, a network node (such as a base station) can provide downlink signaling to a wireless device (such as a UE), which can respond with corresponding uplink signaling indicating one or more angles of arrival, power levels of transmitted / received signals, and the like. Based on the received signaling, the network node or network entity (such as a location management function (LMF)) can perform operations to determine the wireless device's position.

[0028] However, scenarios may arise where such signaling may not be sufficient to determine an accurate positioning determination for a wireless device. For example, a network node may communicate / exchange with a wireless device via a relay. A relay (e.g., a network-controlled relay (NCR)) may be used to receive / forward positioning references used to locate the wireless device. In some cases, such a relay may forward DL / UL signaling between the network node and the wireless device (e.g., with no or minimal processing), with the network node thus being the logical source / destination for DL / UL signaling with respect to the wireless device. However, in such scenarios, the positioning and transmission characteristics (e.g., transmit power level) of the relay should be considered, as the relay is the physical source / destination for positioning purposes.

[0029] Various aspects generally relate to positioning systems. Some aspects more specifically relate to repeater power management for positioning. In some examples, a wireless device may be configured to receive at least one downlink transmission at a receive power level, wherein the at least one downlink transmission is associated with an initial transmit power level including at least one initial power characteristic, the at least one initial power characteristic being different from at least one repeater power characteristic of a repeater transmit power level associated with the at least one downlink transmission, wherein the initial transmit power level and the repeater transmit power level are associated with communications for a positioning session. The wireless device may also be configured to obtain an indication of the at least one repeater power characteristic of the repeater transmit power level. In some examples, a wireless device may be configured to transmit at least one downlink transmission, wherein the at least one downlink transmission is associated with a first transmit power level including at least one first power characteristic. The first wireless device may also be configured to obtain a first indication of a second transmit power level for the at least one downlink transmission, wherein the second transmit power level includes at least one second power characteristic different from the at least one first power characteristic of the first transmit power level, wherein the first transmit power level and the second transmit power level are associated with communications for a positioning session. The first wireless device may be further configured to transmit a second indication of the at least one second power characteristic of the second transmit power level.

[0030] Certain aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used to more accurately determine the location of a wireless device by considering the power level of signaling at a repeater and / or the location of the repeater when performing a positioning session. That is, a network node and / or network entity can be aware of a baseline (e.g., the power characteristics of repeaters in a communication path, rather than the power characteristics of the originating network node) from which the wireless device gathers information for received DL signaling in view of the repeater, and can determine a more accurate location for the wireless device.

[0031] The detailed description set forth below in conjunction 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. The detailed description includes specific details to provide a thorough understanding of the various concepts. However, these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0032] Several aspects of telecommunications 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 can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0033] As an example, an element, or any part 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, systems on a 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 the various functionalities described throughout this 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 to mean instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, processes, functions, or any combination thereof.

[0034] Thus, in one or more example aspects, implementations, and / or use cases, the functionality described 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 code on a computer-readable medium. Computer-readable media include computer storage media. A storage medium can be any available medium that can be accessed by a computer. By way of 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.

[0035] While aspects, implementations, and / or use cases are described herein through the lens of a few examples, additional or different aspects, implementations, and / or use cases may arise in many different arrangements and scenarios. The aspects, implementations, and / or use cases described herein may be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, the aspects, implementations, and / or use cases may arise via integrated chip implementations and other non-module component-based devices (e.g., end-user devices, vehicles, communications equipment, computing devices, industrial equipment, retail / purchase equipment, medical devices, artificial intelligence (AI)-enabled devices, etc.). While some examples may or may not be specifically targeted at use cases or applications, the examples described may have broad applicability. The aspects, implementations, and / or use cases may range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the techniques described herein. In some practical settings, devices incorporating the described aspects and features 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 involve multiple components for both 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 can be practiced in a wide variety of devices of various sizes, shapes, and configurations, including chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, and the like.

[0036] The deployment of a communication system, such as a 5G NR system, can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, a network node, a network entity, a mobility element of the 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 a converged or disaggregated architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), a NR base station, a 5G NB, an access point (AP), a transmit / receive point (TRP), or a cell) can be implemented as a converged base station (also known as a standalone base station or a monolithic base station) or a disaggregated base station.

[0037] A converged base station can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A disaggregated base station can be configured to utilize a protocol stack that is physically or logically distributed across 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 can be implemented within a RAN node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed across one or more other RAN nodes. A DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0038] Base station operation or network design can take into account the aggregated nature of base station functionality. For example, a disaggregated base station can be utilized in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (such as the network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Disaggregation can 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 can enable flexibility in network design. The various units of a disaggregated base station or disaggregated RAN architecture can be configured for wired or wireless communication with at least one other unit.

[0039] Figure 1 FIG100 is a diagram illustrating an example of a wireless communication system and 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, which 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, a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework 105, or both. The CUs 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as the F1 interface. The DUs 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RUs 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.

[0040] Each of the units (i.e., CU 110, DU 130, RU 140, as well as 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 transmit 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 the transmission medium. For example, these units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via the 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 transmit signals to one or more of the other units via the wireless transmission medium.

[0041] In some aspects, the 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), and the like. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by the CU 110. The CU 110 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some implementations, the CU 110 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 units may communicate bidirectionally with the CU-CP units via an interface, such as the E1 interface. As needed, the CU 110 may be implemented to communicate with the DU 130 for network control and signaling.

[0042] The 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, the DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) based at least in part on a functional split, such as those defined by 3GPP. In some aspects, the DU 130 may also host one or more lower PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 130 or with control functions hosted by the CU 110.

[0043] Lower layer functionality may be implemented by one or more RUs 140. In some deployments, a RU 140 controlled by a DU 130 may correspond to a logical node that hosts RF processing functionality or low PHY layer functionality (such as performing fast Fourier transforms (FFTs), inverse FFTs (iFFTs), digital beamforming, physical random access channel (PRACH) extraction and filtering), or both, based at least in part 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) communications with one or more UEs 104. In some implementations, both real-time and non-real-time aspects of control 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 CU 110 in a cloud-based RAN architecture, such as a vRAN architecture.

[0044] The SMO framework 105 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 105 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 105 can be configured to interact with a cloud computing platform (such as Open Cloud (O-Cloud) 190) to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces (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 implementations, the SMO framework 105 can communicate with 4G RAN hardware (such as the Open eNB (O-eNB) 111) via the O1 interface. Additionally, in some implementations, the SMO framework 105 can 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 .

[0045] The non-RT RIC 115 can be configured to include logic that enables 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 in communication with the near-RT RIC 125 (e.g., via an A1 interface). The near-RT RIC 125 can be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions via an interface (e.g., 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.

[0046] In some implementations, to generate AI / ML models 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 at the SMO framework 105 or the non-RT RIC 115 from non-network data sources or from network functions. In some examples, the non-RT RIC 115 or the near-RT RIC 125 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 AI / ML models to execute corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or by creating RAN management policies (such as A1 policies).

[0047] At least one of the CU 110, DU 130, and RU 140 may be referred to as a 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 a UE 104 with access to core network 120. 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 that includes 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 known as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmissions from UE 104 to RU 140 and / or downlink (DL) (also known as forward link) transmissions from RU 140 to UE 104. The communication link may utilize 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. Base station 102 / UE 104 may utilize spectrum with a bandwidth of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.) for each carrier allocated in a carrier aggregation for a total of up to Yx MHz (x component carriers) for transmission in each direction. The 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).

[0048] Certain UEs 104 may communicate with each other using device-to-device (D2D) communication links 158. D2D communication links 158 may utilize DL / UL wireless wide area network (WWAN) spectrum. D2D communication links 158 may utilize 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 accomplished via 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.

[0049] 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 the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the UE 104 / AP 150 may perform a clear channel assessment (CCA) to determine whether the channel is available before communicating.

[0050] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, and so on, based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 extends beyond 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes arises with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, despite being distinct from the extremely high frequency (EHF) band (30 GHz to 300 GHz), which is designated as a "millimeter wave" band by the International Telecommunication Union (ITU).

[0051] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR research has identified the operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz to 24.25 GHz). Frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency 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 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.

[0052] With the above in mind, unless otherwise specified, if the term "sub-6 GHz" or the like 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. Furthermore, unless otherwise specified, if the term "millimeter wave" or the like 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.

[0053] 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 signals 182 to UE 104 in one or more transmit directions. UE 104 may receive beamformed signals from base station 102 in one or more receive directions. UE 104 may also transmit beamformed signals 184 to base station 102 in one or more transmit directions. Base station 102 may receive beamformed signals from UE 104 in one or more receive directions. Base station 102 / UE 104 may perform beam training to determine the optimal receive and transmit directions for each of base station 102 / UE 104. The transmit and receive directions of base station 102 may or may not be the same. The transmit and receive directions of UE 104 may or may not be the same.

[0054] The base station 102 may include and / or be referred to as a gNB, Node B, eNB, access point, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP, network node, network entity, network equipment, or some other suitable terminology. The base station 102 may be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, a converged (monolithic) base station having 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 collection of base stations that may include disaggregated base stations and / or converged base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0055] 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 handles 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. The one or more location servers 168 are exemplified 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. 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 positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and 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. Locating the UE 104 may involve signal measurements, position estimation, and optional velocity calculation based on these measurements. Signal measurements may be performed by the UE 104 and / or the base station 102 serving the UE 104. The measured signals may be based on one or more of a satellite positioning system (SPS) 170 (e.g., one or more of a global navigation satellite system (GNSS), 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), NR enhanced cell ID (NR E-CID) methods, NR signals (e.g., multi-round trip time (multi-RTT), DL angle of departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning), and / or other systems / signals / sensors.

[0056] Examples of UE 104 include a cellular phone, a smartphone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., an MP3 player), a camera, a game console, a tablet device, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similarly functional device. Some of UE 104 may be referred to as IoT devices (e.g., a parking meter, a gas pump, a toaster, a vehicle, a heart rate monitor, etc.). UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network collectively and / or individually.

[0057] Reference again Figure 1In certain aspects, UE 104 may include a power management component 198 ("component 198") that may be configured to receive at least one DL transmission at a received power level, wherein the at least one DL transmission is associated with an initial transmit power level comprising at least one initial power characteristic that is different from at least one relay power characteristic of a relay transmit power level associated with the at least one DL transmission, wherein the initial transmit power level and the relay transmit power level are associated with communications for a positioning session. Component 198 may also be configured to obtain an indication of the at least one relay power characteristic of the relay transmit power level. In certain aspects, base station 102 may include a power management component 199 ("component 199") that may be configured to transmit at least one DL transmission, wherein the at least one DL transmission is associated with a first transmit power level comprising at least one first power characteristic. Component 199 may also be configured to obtain a first indication of a second transmit power level for the at least one DL transmission, wherein the second transmit power level includes at least one second power characteristic different from the at least one first power characteristic of the first transmit power level, wherein the first transmit power level and the second transmit power level are associated with communications for a positioning session. Component 199 may be further configured to transmit a second indication of the at least one second power characteristic of the second transmit power level. In various aspects, component 199 may be configured to transmit adjustment information to the LMF, wherein the adjustment information includes at least one of a first range for a power level adjustment associated with the second transmit power level or a second range for a gain adjustment associated with the second transmit power level. In such aspects, component 199 may be configured to receive a request from the LMF, wherein the request indicates at least one of: a first target value within the first range for a power level adjustment, a first relative adjustment value within the first range for a power level adjustment, a second target value within the second range for a gain adjustment, or a second relative adjustment value within the second range for a gain adjustment. In such aspects, component 199 can be configured to transmit, to a network controlled repeater (NCR), an indication of at least one of a first target value, a first relative adjustment value, a second target value, or a second relative adjustment value. In various aspects, component 199 can be configured to receive a positioning information request from an LMF, wherein the positioning information request indicates a requested transmission characteristic associated with at least one synchronization signal block (SSB), the requested transmission characteristic comprising at least one of: a first target value for a power level adjustment of the at least one SSB, a first relative adjustment value for a power level adjustment of the at least one SSB, a second target value for a gain adjustment of the at least one SSB, or a second relative adjustment value for a gain adjustment of the at least one SSB.In such aspects, component 199 can be configured to transmit an indication of at least one of a first target value, a first relative adjustment value, a second target value, or a second relative adjustment value for the NCR. That is, aspects provide for relay power management for positioning measurements that implements extensions of TRP information (e.g., SSB transmit power and PRS resource transmit power) and / or PRS configuration responses (e.g., PRS resource transmit power) to provide transmit power and gain characteristics of relays (e.g., NCRs) for network nodes and network entities to be used for positioning determination of wireless devices in a positioning session.

[0058] Figure 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B is a diagram 230 illustrating an example of a DL channel within a 5G NR subframe. Figure 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D is a diagram 280 illustrating an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be frequency division duplex (FDD) (wherein, for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL), or time division duplex (TDD) (wherein, for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL). In the examples provided in Figures 2A and 2C, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (mostly DL), where D stands for DL, U stands for UL, and F stands for flexible use between DL / UL, and subframe 3 is configured with slot format 1 (wherein all are UL). While 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 mix of DL, UL, and flexible symbols. The UE is configured with the slot format via a received slot format indicator (SFI), either dynamically via DL control information (DCI) or semi-statically / statically via radio resource control (RRC) signaling. Note that the following description also applies to the 5G NR frame structure as TDD.

[0059] Figures 2A through 2D illustrate a frame structure, and aspects of the present disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more slots. A subframe may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For a normal CP, each slot may include 14 symbols, and for an extended CP, each slot may include 12 symbols. Symbols on the DL may be CP-orthogonal frequency division multiplexing (OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or discrete Fourier transform (DFT)-spread OFDM (DFT-s-OFDM) symbols (for power-limited scenarios; limited to single-stream transmission). The number of slots within a subframe depends on the CP and the numerology set. The numerology defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration is scalable with 1 / SCS.

[0060] µ SCS#timg# cyclic prefix 0 15 normal 1 30 normal 2 60 Normal, Extended 3 120 normal 4 240 normal 5 480 normal 6 960 normal

[0061] Table 1: Parameter set, SCS and CP

[0062] For normal CP (14 symbols / slot), different parameter sets µ 0 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 per slot and 2 per subframe. µ time slots. The subcarrier spacing can be equal to ,in For parameter sets 0 through 4, the subcarrier spacing for parameter set µ=0 is 15 kHz, and for parameter set µ=4, the subcarrier spacing is 240 kHz. Symbol length / duration is inversely correlated with subcarrier spacing. Figures 2A through 2D provide examples for a normal CP with 14 symbols per slot and a parameter set µ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 µs. Within a frame set, there may be one or more different bandwidth parts (BWPs) frequency-division multiplexed (see Figure 2B). Each BWP may have a specific parameter set and CP (normal or extended).

[0063] A resource grid can be used to represent the frame structure. Each slot consists of 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.

[0064] As illustrated in Figure 2A, some of the REs carry reference (pilot) signals (RSs) for the UE. The RSs may include a demodulation RS (DM-RS) (indicated as R for one specific configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) used for channel estimation at the UE. The RSs may also include a beamforming RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0065] Figure 2B illustrates examples of various downlink channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs). Each CCE consists of six resource element groups (REGs), with each REG comprising 12 contiguous REs within an OFDM symbol of a RB. The PDCCH within a BWP is referred to as a control resource set (CORESET). During PDCCH monitoring opportunities within a CORESET, a UE is configured to monitor PDCCH search spaces (e.g., common search space, UE-specific search space) for PDCCH candidates with different DCI formats and aggregation levels. Additional BWPs may be located at higher and / or lower frequencies across the channel bandwidth. The primary synchronization signal (PSS) may be within symbol 2 of specific subframes of a frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. The secondary synchronization signal (SSS) may be within symbol 4 of specific subframes of a 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), which carries the master information block (MIB), can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also known 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 via the PBCH (such as the system information block (SIB)), and paging messages.

[0066] As illustrated in Figure 2C , some of the REs carry DM-RS (indicated as R for a specific configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit the DM-RS for the Physical Uplink Control Channel (PUCCH) and the DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be sent in the first or first two symbols of the PUSCH. The PUCCH DM-RS can be sent in different configurations depending on whether a short or long PUCCH is transmitted and the specific PUCCH format used. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be sent in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the comb structures within the comb structure. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0067] FIG2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, 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 buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0068] Figure 3Figure 3 is a block diagram of a base station 310 communicating with a UE 350 in an access network. In the DL, Internet Protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements Layer 3 and Layer 2 functionality. Layer 3 includes 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 Medium Access Control (MAC) layer. The controller / processor 375 provides RRC layer functionality 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 functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with delivery of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0069] The transmit (TX) processor 316 and 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 transport channels, forward error correction (FEC) coding / decoding of transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles the mapping onto signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-order phase-shift keying (M-PSK), and M-order quadrature amplitude modulation (M-QAM)). The coded and modulated symbols are then separated into parallel streams. Each stream is then mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying the time-domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. The channel estimates may be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier using a corresponding spatial stream for transmission.

[0070] At the UE 350, each receiver 354Rx receives a signal via 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 functionality associated with various signal processing functions. The RX processor 356 performs 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. 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, along with the reference signal, are recovered and demodulated by determining the most likely signal constellation point transmitted by the base station 310. These soft decisions may 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 a controller / processor 359, which implements layer 3 and layer 2 functionality.

[0071] 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 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 an ACK and / or NACK protocol to support HARQ operations.

[0072] Similar to the functionality described in conjunction with DL transmissions 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 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 functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0073] Channel estimates derived by the channel estimator 358 based on a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0074] 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 the RX processor 370.

[0075] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. Memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and 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.

[0076] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform a combined Figure 1 At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform a combined Figure 1 Aspects of component 199.

[0077] Figure 4 FIG4 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 Receive DL Positioning Reference Signal (PRS) (DL-PRS) 410. TRP 406 may be at time T SRS_RX Receive UL-SRS 412 and at time T PRS_TX 410. The UE 404 may receive the DL-PRS 410 before transmitting the UL-SRS 412, or may transmit the UL-SRS 412 before receiving the DL-PRS 410. In both cases, the positioning server (eg, location server 168) or the UE 404 may determine the UL-SRS 412 based on the || T SRS_RX – T PRS_TX | – |T SRS_TX – T PRS_RX || to determine RTT 414. Thus, multi-RTT positioning may utilize UE Rx-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 uses assistance data received from the positioning server to measure the UE Rx-Tx time difference measurement (and optionally the DL-PRS-RSRP of the received signal), and TRP 402, 406 uses assistance data received from the positioning server to measure the gNB Rx-Tx time difference measurement (and optionally the UL-SRS-RSRP of the received signal). These measurements can be used at the positioning server or UE 404 to determine the 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.

[0078] DL-AoD positioning may utilize the measured DL-PRS-RSRP of downlink signals received at a UE 404 from multiple TRPs 402, 406. The UE 404 uses assistance data received from a positioning server to measure the DL-PRS-RSRP of the received signals, and the resulting measurements, along with the azimuth angle of departure (A-AoD), the zenith angle of departure (Z-AoD), and other configuration information, are used to position the UE 404 relative to neighboring TRPs 402, 406.

[0079] DL-TDOA positioning may utilize the DL Reference Signal Time Difference (RSTD) (and optionally DL-PRS-RSRP) of downlink signals received at a UE 404 from multiple TRPs 402, 406. The UE 404 uses assistance data received from a positioning server to measure the DL RSTD (and optionally DL-PRS-RSRP) of the received signals, and the resulting measurements, along with other configuration information, are used to position the UE 404 relative to neighboring TRPs 402, 406.

[0080] UL-TDOA positioning may utilize the UL relative time of arrival (RTOA) (and optionally UL-SRS-RSRP) of uplink signals transmitted from a UE 404 at multiple TRPs 402, 406. The TRPs 402, 406 use assistance data received from a positioning server to measure the UL-RTOA (and optionally UL-SRS-RSRP) of the received signals, and the resulting measurements, along with other configuration information, are used to estimate the position of the UE 404.

[0081] 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 a 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 along with other configuration information to estimate the position of the UE 404.

[0082] 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 / refine measurements, and / or replace / provide missing information.

[0083] For the purposes of this disclosure, a positioning session may refer to the transmission, reception, and measurement of reference signals for the purpose of determining a positioning result or status (e.g., position, heading, velocity, etc.) of a target entity. The target entity may be any object (e.g., a person, a vehicle, a wireless device (such as a UE), etc.) for which a positioning session is performed, for example, to determine its position, velocity, heading, etc.

[0084] A wireless communication network and / or wireless device may utilize measurements associated with specific signaling to determine one or more angles of arrival, power levels of transmitted / received signals, and the like for positioning operations. As an example, a network node (such as a base station) may provide downlink signaling to a wireless device (such as a UE), which may respond with corresponding uplink signaling indicating one or more angles of arrival, power levels of transmitted / received signals, and the like. Based on the received signaling, the network node or a network entity (such as a LMF) may perform operations to determine the wireless device's position. However, scenarios may arise where such signaling may not be sufficient to determine an accurate positioning determination for the wireless device. For example, a network node may communicate / exchange information with a wireless device via a relay. A relay (e.g., a network-controlled relay (NCR)) may be used to receive / forward positioning references used to locate the wireless device. In some cases, such a relay may forward downlink / uplink signaling between the network node and the wireless device (e.g., with no or minimal processing), and the network node may thus be the logical source / destination of downlink / uplink signaling for the wireless device. However, in such scenarios, the positioning and transmission characteristics of the repeaters should be considered since the repeaters are the physical sources / destination for positioning purposes.

[0085] Aspects of repeater power management for positioning herein enable improved and more accurate positioning determination for wireless devices. In some examples, a wireless device may be configured to receive at least one downlink transmission at a receive power level, wherein the at least one downlink transmission is associated with an initial transmit power level including at least one initial power characteristic, the at least one initial power characteristic being different from at least one repeater power characteristic of a repeater transmit power level associated with the at least one downlink transmission, wherein the initial transmit power level and the repeater transmit power level are associated with communications for a positioning session. The wireless device may also be configured to obtain an indication of the at least one repeater power characteristic of the repeater transmit power level. In some examples, a wireless device may be configured to transmit at least one downlink transmission, wherein the at least one downlink transmission is associated with a first transmit power level including at least one first power characteristic. A first wireless device may also be configured to obtain a first indication of a second transmit power level for the at least one downlink transmission, wherein the second transmit power level includes at least one second power characteristic different from the at least one first power characteristic of the first transmit power level, wherein the first transmit power level and the second transmit power level are associated with communications for a positioning session. The first wireless device may be further configured to transmit a second indication of the at least one second power characteristic of the second transmit power level.

[0086] Certain aspects of the subject matter described in this disclosure consider the power level of signaling at a relay and / or the position of the relay when performing a positioning session to more accurately determine the position of a wireless device. That is, a network node and / or network entity may be aware of a baseline (e.g., the power characteristics of relays in a communication path, rather than the power characteristics of an originating network node) from which the wireless device gathers information for received DL signaling in view of the relay, and may determine a more accurate position for the wireless device.

[0087] For example, Figure 5 FIG. 5 is a diagram 500 illustrating a repeater 506 in various aspects. Figure 5 As shown, the relay 506 can receive a DL signal 508 from the network node 502 and forward the DL signal (shown as signal 508′) to a wireless device (e.g., a remote UE 504). Similarly, the relay 506 can receive a UL signal 510 from the remote UE 504 and forward the UL signal (shown as signal 510′) to the network node 502. Although the relay 506 can forward the DL signal 508 and / or the UL signal 510 (e.g., without processing or with minimal processing), the network node 502 (e.g., a base station) can be the logical or originating source / destination of the DL / UL signaling, respectively, and the relay 506 can be considered the physical source / destination for positioning purposes.

[0088] For example, the power level of the DL signal 508' received at the remote UE 504 from the relay 506 may be different from the DL signal 508 originally transmitted from the network node 502. As an example, due to the gain configuration / capability of the relay 506, the backhaul channel path loss, etc., the power level of the DL SSB / PRS of the DL signal 508' received at the remote UE 504 may be different from the DL signal 508 originally transmitted from the network node 502. When the transmit power level of the DL SSB / PRS is exchanged between the wireless device and a network entity (e.g., LMF) as part of the TRP information and / or PRS configuration response for a positioning session, the network entity may not be aware of the impact caused by the relay 506 when receiving the DL signal 508'. Aspects of the present disclosure for relay power management for positioning enable improved and more accurate positioning determination for the wireless device. For example, the transmit power characteristics of a DL reference signal (DL-RS) (such as an SSB, a DL-PRS, etc.) of a relay (such as the relay 506) may be transmitted at a power level that varies based on and / or according to the DL-RSRP of the relay 506, the amplification gain of the relay 506, etc. The DL-RSRP of the relay 506 may vary due to backhaul channel variations, beam changes, etc., and the amplification gain of the relay 506 may vary to avoid self-oscillation, power amplifier saturation, etc. Alternatively, the relay 506 may be configured to forward the DL-RS signal at a constant output power, and in such a case, the gain may be autonomously varied by the relay 506 to compensate for RSRP variations, while setting a maximum value that may be sufficiently small to avoid self-oscillation or power amplifier saturation.

[0089] The network node 502 may know and / or set the output transmit power of the repeater 506 and exchange associated information with the LMF via core network signaling. However, because the repeater 506 may be configured to forward signals at a constant gain, or because the gain setting of the repeater 506 may be dynamically / autonomously changed to avoid self-oscillation and / or power amplifier saturation, or in the absence of power control for the repeater 506, the network node 502 may know the range of values ​​(or maximum values) for the transmit / output power level but may not know the actual value, the amplification gain, or when the repeater 506 dynamically changes the amplification gain / transmit power level, the exact value configured at the repeater 506 may not be dynamically indicated to the LMF.

[0134] A wireless communication network and / or wireless device may utilize measurements associated with specific signaling to determine one or more angles of arrival, power levels of transmitted / received signals, and the like for positioning operations. As an example, a network node (such as a base station) may provide downlink signaling to a wireless device (such as a UE), which may respond with corresponding uplink signaling indicating one or more angles of arrival, power levels of transmitted / received signals, and the like. Based on the received signaling, the network node or a network entity (such as a LMF) may perform operations to determine the wireless device's position. However, scenarios may arise where such signaling may not be sufficient to determine an accurate positioning determination for the wireless device. For example, a network node may communicate / exchange information with a wireless device via a relay. A relay (e.g., a network-controlled relay (NCR)) may be used to receive / forward positioning references used to locate the wireless device. In some cases, such a relay may forward downlink / uplink signaling between the network node and the wireless device (e.g., with no or minimal processing), and the network node may thus be the logical source / destination of downlink / uplink signaling for the wireless device. However, in such scenarios, the positioning and transmission characteristics of the repeaters should be considered since the repeaters are the physical sources / destination for positioning purposes.

[0135] Aspects of repeater power management for positioning herein enable improved and more accurate positioning determination for wireless devices. In some examples, a wireless device may be configured to receive at least one downlink transmission at a receive power level, wherein the at least one downlink transmission is associated with an initial transmit power level including at least one initial power characteristic, the at least one initial power characteristic being different from at least one repeater power characteristic of a repeater transmit power level associated with the at least one downlink transmission, wherein the initial transmit power level and the repeater transmit power level are associated with communications for a positioning session. The wireless device may also be configured to obtain an indication of the at least one repeater power characteristic of the repeater transmit power level. In some examples, a wireless device may be configured to transmit at least one downlink transmission, wherein the at least one downlink transmission is associated with a first transmit power level including at least one first power characteristic. A first wireless device may also be configured to obtain a first indication of a second transmit power level for the at least one downlink transmission, wherein the second transmit power level includes at least one second power characteristic different from the at least one first power characteristic of the first transmit power level, wherein the first transmit power level and the second transmit power level are associated with communications for a positioning session. The first wireless device may be further configured to transmit a second indication of the at least one second power characteristic of the second transmit power level.

[0136] Certain aspects of the subject matter described in this disclosure consider the power level of signaling at a relay and / or the position of the relay when performing a positioning session to more accurately determine the position of a wireless device. That is, a network node and / or network entity may be aware of a baseline (e.g., the power characteristics of relays in a communication path, rather than the power characteristics of an originating network node) from which the wireless device gathers information for received DL signaling in view of the relay, and may determine a more accurate position for the wireless device.
