Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. non-provisional patent application serial number 17 / 452,553, entitled “USE OF EXISTING RRMMEASUREMENT GAP FOR PRS PROCESSING” and filed on October 27, 2021, which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates generally to communication systems and, more particularly, to wireless communications related to positioning. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcast. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at city, country, region, and even global levels. An example telecommunication standard is 5G New Air (NR). 5G NR is part of the continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)) and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable low latency communication (URLLC). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. It is necessary to further improve 5G NR technology. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0006] Some communication systems may also support a variety of cellular network-based positioning technologies, in which the geographic location of a wireless device may be determined based on measuring radio signals exchanged between the wireless device and other wireless devices. For example, the distance between the wireless device and a transmit receive point (TRP) may be estimated based on the time it takes for a reference signal (e.g., a positioning reference signal (PRS)) transmitted from the TRP to reach the wireless device. Other examples of cellular network-based positioning technologies may include downlink-based, uplink-based, and / or downlink- and uplink-based positioning methods. Summary of the invention

[0007] A simplified summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an extensive overview of all contemplated aspects, and is neither intended to identify key or important elements of all aspects, nor to describe the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be presented later.

[0008] In one aspect of the present disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus receives a first configuration for at least one radio resource management (RRM) measurement gap. The apparatus receives one or more positioning reference signals (PRS) prior to the at least one RRM measurement gap. The apparatus identifies whether the processing availability of a user equipment (UE) during the at least one RRM measurement gap is sufficient to process the one or more PRSs. The apparatus processes the one or more PRSs, wherein: in response to the processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap; and in response to the UE lacking the processing availability sufficient to process the one or more PRSs during the at least one RRM measurement gap, the one or more PRSs are processed at least partially outside the at least one RRM measurement gap.

[0009] In another aspect of the present disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus transmits a first configuration for at least one RRM measurement gap to a UE. The apparatus transmits one or more PRSs to the UE before the at least one RRM measurement gap. The apparatus receives a request for at least one PRS processing gap from the UE based on the at least one RRM measurement gap being insufficient to process the one or more PRSs.

[0037] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations with which the concepts described herein may be practiced. In order to provide a thorough understanding of the various concepts, the detailed description includes specific details. However, it is apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0038] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0039] For example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system", which includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform various functionalities described throughout the present disclosure. One or more processors in a processing system can execute software. Whether it is referred to as software, firmware, middleware, microcode, hardware description language or other names, software should be widely interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc.

[0040] Accordingly, in one or more example embodiments, the described functions can be implemented with hardware, software or any combination thereof. If implemented with software, the function can be stored or encoded on a computer-readable medium as one or more instructions or codes. Computer-readable media include computer storage media. Storage media can be any available medium that can be accessed by a computer. As an example and not limitation, 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 instructions or data structure forms that can be accessed by a computer.

[0041] Although aspects and embodiments are described in this application by the illustration of some examples, it will be understood by those skilled in the art that additional specific implementations and use cases may be generated in many other arrangements and scenarios. The innovation described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, specific implementations and / or uses can be generated via integrated chip specific implementations and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, artificial intelligence (AI) enabled devices, etc.). Although some examples may or may not specifically point to use cases or applications, the applicability of various types of described innovations may occur. Specific implementations can be the range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregation, distributed or original equipment manufacturer (OEM) equipment or systems that merge one or more aspects of the described innovation. In some actual environments, the equipment that merges the various aspects and features described may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / accumulators, etc.). The innovations described herein are intended to be practiced in a variety of devices of different sizes, shapes, and configurations, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc.

[0042] Figure 11 is a diagram 100 showing an example of a wireless communication system and access network. The wireless communication system (which is also referred to as a wireless wide area network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell includes a base station. A small cell includes a femto cell, a pico cell, and a micro cell.

[0043] Various aspects presented herein can improve the performance and efficiency of UE positioning sessions by reducing the number of PRS processing gaps requested by the UE. Various aspects presented herein can enable the UE to utilize one or more RRMMGs to process PRS based on one or more conditions so that the UE can process the PRS without requesting a processing gap for the PRS from a serving base station.

[0044] In certain aspects, the UE 104 may include a PRS processing gap determination component 198 configured to process the PRS using one or more RRM MGs without requesting a processing gap for the PRS from a serving base station. In one configuration, the PRS processing gap determination component 198 may be configured to receive a first configuration for at least one RRM measurement gap. In such a configuration, the PRS processing gap determination component 198 may receive one or more PRSs prior to the at least one RRM measurement gap. In such a configuration, the PRS processing gap determination component 198 may identify whether the processing availability of the UE during the at least one RRM measurement gap is sufficient to process the one or more PRSs. In such a configuration, the PRS processing gap determination component 198 may process the one or more PRSs, wherein: in response to the processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap; and in response to the lack of processing availability of the UE during the at least one RRM measurement gap sufficient to process the one or more PRSs, the one or more PRSs are processed at least partially outside of the at least one RRM measurement gap.

[0045] In certain aspects, the base station 102 / 180 (or the TRP of the base station 102 / 180) may include a PRS processing gap configuration component 199 configured to provide at least one PRS processing gap to the UE based on a request of the UE and / or based on whether the UE has sufficient processing availability to process the PRS within one or more RRM MGs. In one configuration, the PRS processing gap configuration component 199 may be configured to transmit a first configuration for at least one RRM measurement gap to the UE. In such a configuration, the PRS processing gap configuration component 199 may transmit one or more PRSs to the UE prior to the at least one RRM measurement gap. In such a configuration, the PRS processing gap configuration component 199 may receive a request for at least one PRS processing gap from the UE based on at least one RRM measurement gap being insufficient to process the one or more PRSs. In such a configuration, the PRS processing gap configuration component 199 may transmit a second configuration for at least one PRS processing gap to the UE based on the request.

[0046] The base station 102 configured for 4G LTE (which is collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can be connected to the EPC 160 through a first backhaul link 132 (e.g., an S1 interface). The base station 102 configured for 5G NR (which is collectively referred to as the Next Generation RAN (NG-RAN)) can be connected to the core network 190 through a second backhaul link 184. Among other functions, the base station 102 can perform one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 may communicate with each other directly or indirectly (eg, via the EPC 160 or the core network 190) via a third backhaul link 134 (eg, an X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 may be wired or wireless.

[0047] In some aspects, the base station 102 or 180 may be referred to as a RAN and may include aggregated components or disaggregated components. As an example of a disaggregated RAN, the base station may include a central unit (CU) 103, one or more distributed units (DU) 105, and / or one or more remote units (RU) 109, such as Figure 1As shown. The RAN can be decomposed by using the split between RU 109 and the aggregated CU / DU. The RAN can be decomposed by using the split between CU 103, DU 105 and RU 109. The RAN can be decomposed by using the split between CU 103 and the aggregated DU / RU. The CU 103 and one or more DUs 105 can be connected via an F1 interface. DU 105 and RU109 can be connected via a forwarding interface. The connection between CU 103 and DU 105 can be referred to as a mid-haul, and the connection between DU 105 and RU 109 can be referred to as a forwarding. The connection between CU 103 and the core network can be referred to as a backhaul. The RAN can be based on the functional split between various components of the RAN (e.g., between CU 103, DU 105 or RU 109). The CU can be configured to perform one or more aspects of a wireless communication protocol (e.g., one or more layers of a protocol stack), and the DU can be configured to handle other aspects of the wireless communication protocol (e.g., other layers of a protocol stack). In different embodiments, the split between the layers handled by the CU and the layers handled by the DU may occur at different layers of the protocol stack. As a non-limiting example, the DU 105 may provide a logical node for hosting at least a portion of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer based on the functional split. The RU may provide a logical node configured to host at least a portion of the PHY layer and radio frequency (RF) processing. The CU 103 may host, for example, higher layer functions above the RLC layer, such as the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer. In other embodiments, the split between the layer functions provided by the CU, DU, or RU may be different.

[0048] The access network may include one or more integrated access and backhaul (IAB) nodes 111 that exchange wireless communications with UE 104 or other IAB nodes 111 to provide access and backhaul to the core network. In an IAB network of multiple IAB nodes, an anchor node may be referred to as an IAB donor. An IAB donor may be a base station 102 or 180 that provides access to a core network 190 or EPC 160 and / or control of one or more IAB nodes 111. An IAB donor may include a CU 103 and a DU 105. An IAB node 111 may include a DU 105 and a mobile terminal (MT) 113. The DU 105 of an IAB node 111 may operate as a parent node, and the MT 113 may operate as a child node.

[0049] Base station 102 can communicate wirelessly with UE 104. Each base station in base station 102 can provide communication coverage for a corresponding geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102' can have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including both small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include a home evolved Node B (eNB) (HeNB), which can provide services to a restricted group called a closed subscriber group (CSG). The communication link 120 between base station 102 and UE 104 can include an uplink (UL) (also referred to as a reverse link) transmission from UE 104 to base station 102 and / or a downlink (DL) (also referred to as a forward link) transmission from base station 102 to UE 104. The communication link 120 can use multiple input multiple output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link can go through one or more operators. For each carrier allocated in the carrier aggregation for transmission in each direction with a total of up to Yx MHz (x component carriers), the base station 102 / UE 104 may use spectrum with a bandwidth of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.). 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). The 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).

[0050] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0051] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154, e.g., in a 5 GHz unlicensed spectrum, etc. When communicating in an unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) prior to communication to determine whether a channel is available.

[0052] The small cell 102' may operate in a licensed and / or unlicensed spectrum. When operating in an unlicensed spectrum, the small cell 102' may employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as used by the Wi-Fi AP 150. The small cell 102' employing NR in the unlicensed spectrum may improve the coverage of the access network and / or increase the capacity of the access network.

[0053] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified with the frequency range names FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, in various documents and articles, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0054] 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 designations FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6GHz-71GHz), FR4 (52.6Hz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0055] In view of the above aspects, unless otherwise specifically stated, it should be understood that if used in this article, the term "sub-6 GHz" and the like can broadly refer to frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" and the like are used in this article, it can broadly refer to frequencies that can include mid-band frequencies, can be within FR2, FR4, FR2-2 and / or FR5, or can be within the EHF band.

[0056] The base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), may include and / or be referred to as an eNB, a gNodeB (gNB), or another type of base station. Some base stations, such as gNB 180, may operate in traditional sub-6 GHz spectrum, in millimeter wave frequencies, and / or near millimeter wave frequencies to communicate with UE 104. When the gNB 180 operates in millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. The millimeter wave base station 180 may utilize beamforming 182 with the UE 104 to compensate for path loss and short range. The base station 180 and the UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0057] The base station 180 may transmit beamformed signals in one or more transmit directions 182' to the UE 104. The UE 104 may receive the beamformed signals from the base station 180 in one or more receive directions 182". The UE 104 may also transmit beamformed signals in one or more transmit directions to the base station 180. The base station 180 may receive beamformed signals in one or more receive directions from the UE 104. The base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of the base station 180 / UE 104. The transmit direction and receive direction of the base station 180 may be the same or different. The transmit and receive directions of the UE 104 may be the same or different.

[0058] The EPC 160 may include a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a packet data network (PDN) gateway 172. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Typically, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation and other functions. The PDN gateway 172 and the BM-SC 170 are connected to IP services 176. The IP services 176 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services. The BM-SC 170 may provide functionality for MBMS user service provision and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services in a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS traffic to base stations 102 belonging to a multicast broadcast single frequency network (MBSFN) area that broadcasts a specific service, and may be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0059] The core network 190 may include an access and mobility management function unit (AMF) 192, other AMFs 193, a session management function unit (SMF) 194, and a user plane function unit (UPF) 195. AMF 192 may communicate with a unified data management (UDM) 196. AMF 192 is a control node that handles signaling between UE 104 and the core network 190. In general, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 is connected to IP services 197. IP services 197 may include the Internet, intranet, IP multimedia subsystem (IMS), packet switching (PS) streaming (PSS) services, and / or other IP services.

[0060] Base stations may include and / or be referred to as gNBs, Node Bs, eNBs, access points, base transceiver stations, radio base stations, radio transceivers, transceiver functions, basic service sets (BSSs), extended service sets (ESSs), transmit receive points (TRPs), or some other suitable terminology. Base stations 102 provide access points to EPC 160 or core network 190 for UEs 104. Examples of UEs 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radio units, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some of UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as 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, handheld device, user agent, mobile client, client or some other appropriate term. In some scenarios, the term UE may also be applied to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network together and / or individually.

[0061] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B is a diagram 230 illustrating an example of DL channels 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 UL channels 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 the subcarrier set are dedicated to either DL or UL), or can be time division duplex (TDD) (wherein, for a particular set of subcarriers (carrier system bandwidth), subframes within the subcarrier set are dedicated to both DL and UL). Figure 2A , Figure 2CIn the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown with slot formats 1 and 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are DL and UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. The UE is configured with the slot format through the received slot format indicator (SFI) (dynamically configured through DL control information (DCI) or semi-statically / statically controlled through radio resource control (RRC) signaling). Note that the following description also applies to the 5GNR frame structure as TDD.

[0062] FIG. 2A to FIG. 2D The frame structure is illustrated, and various aspects of the present disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 subframes (1ms) of the same size. Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4 or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For a normal CP, each time slot may include 14 symbols, and for an extended CP, each time slot may include 12 symbols. The symbol on the DL may be a CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) extended OFDM (DFT-s-OFDM) symbol (also known as a single carrier frequency division multiple access (SC-FDMA) symbol) (for power-limited scenarios; limited to single-stream transmission). The number of slots within a subframe is based on the CP and numerology. The numerology defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration, which is equal to 1 / SCS.

[0063]

[0064] For normal CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Accordingly, for normal CP and parameter set μ, there are 14 symbols / slot and 2 μ timeslots / subframe. The subcarrier spacing can be equal to 2 μ*15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example of a parameter set μ=2 with a normal CP of 14 symbols per slot and 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is about 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP can have a specific parameter set and CP (normal or extended).

[0065] A resource grid may be used to represent the frame structure. Each slot includes a resource block (RB) (also called a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a number of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0066] like Figure 2A As shown in , some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0067] Figure 2BExamples of various DL channels within a subframe of an illustrated frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in one OFDM symbol of an RB. The PDCCH within a BWP may be referred to as a control resource set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during a PDCCH monitoring opportunity on the CORESET, wherein the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identity. The secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also called 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 (such as system information blocks (SIBs)) that is not transmitted through the PBCH, and paging messages.

[0068] like Figure 2C As shown, some 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 the DM-RS of the physical uplink control channel (PUCCH) and the DM-RS of the physical uplink shared channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or first 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 comb teeth. The SRS can be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0069] Figure 2DExamples of various UL channels within a subframe of an example frame. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0070] Figure 3 3 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, IP packets from the EPC 160 may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 functionality and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides: RRC layer functionality associated with broadcasting of system information (e.g., MIB, 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 transmission of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0071] 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) decoding / 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 for the signal constellation diagram based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols may then be divided into parallel streams. Subsequently, each stream may be 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 generate a physical channel for carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived from reference signals and / or channel state feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX may modulate a radio frequency (RF) carrier with a corresponding spatial stream for transmission.

[0072] At the UE 350, each receiver 354RX receives a signal through its corresponding antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be merged 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 symbol on each subcarrier and the reference signal are recovered and demodulated by determining the signal constellation point most likely to be transmitted by the base station 310. These soft decisions can be based on the channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted on the physical channel by base station 310. The data and control signals are then provided to controller / processor 359, which implements layer 3 functionality and layer 2 functionality.

[0073] 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 from the EPC 160. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0074] 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 transmission 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.

[0075] The TX processor 368 may use channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the base station 310 to select appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a corresponding spatial stream for transmission.

[0076] 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 respective antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to a RX processor 370.

[0077] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets from the UE 350. The IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0078] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform operations related to Figure 1 The PRS processing gap determination component 198 combines various aspects.

[0079] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform operations related to Figure 1 The PRS processing gap configuration component 199 combines various aspects.

[0080] The network may support several cellular network-based positioning techniques, such as downlink-based positioning methods, uplink-based positioning methods, and / or downlink and uplink-based positioning methods. Downlink-based positioning methods may include observed time difference of arrival (OTDOA) (e.g., in LTE), downlink time difference of arrival (DL-TDOA) (e.g., in NR), and / or downlink angle of departure (DL-AoD) (e.g., in NR). In the OTDOA or DL-TDOA positioning procedure, the UE may measure the difference between each arrival time (ToA) of a reference signal (e.g., positioning reference signal (PRS)) received from a paired base station (referred to as reference signal time difference (RSTD) measurement or arrival time difference (TDOA) measurement), and report these differences to a positioning entity (e.g., location management function (LMF)). For example, the UE may receive identifiers (IDs) of a reference base station (e.g., a serving base station) and multiple non-reference base stations in the assistance data. The UE may then measure the RSTD between the reference base station and each non-reference base station. Based on the known positions of the base stations involved and the RSTD measurements, the positioning entity can estimate the position of the UE. In other words, the position of the UE can be estimated based on measuring reference signals transmitted between the UE and one or more base stations and / or the transmit receive points (TRPs) of one or more base stations. Therefore, the PRS can enable the UE to detect and measure adjacent TRPs and perform positioning based on the measurements. For the purposes of this disclosure, the suffixes "based on..." and "assisted by..." may refer to a node responsible for performing positioning calculations (and may also provide measurements) and a node that provides measurements (but may not perform positioning calculations), respectively. For example, the operation of the UE providing measurements to a base station / positioning entity for calculating a positioning estimate may be described as "UE-assisted", "UE-assisted positioning" and / or "UE-assisted positioning calculation", while the operation of the UE calculating its own positioning may be described as "UE-based", "UE-based positioning" and / or "UE-based positioning calculation".

[0081] In some examples, the term "TRP" may refer to one or more antennas of a base station, and the term "base station" may refer to a complete unit (e.g., base station 102 / 180) including aggregated or disaggregated components, such as a combination of Figure 1Described. For example, as an example of a decomposed RAN, a base station may include a CU, one or more DUs, one or more RUs, and / or one or more TRPs. One or more decomposed components may be located at different locations. For example, different TRPs may be located at different geographical locations. In another example, a TRP may refer to a geographically co-located set of antennas (e.g., an antenna array (having one or more antenna elements)) that supports transmit point (TP) and / or receive point (RP) functions. Thus, a base station may transmit signals to and / or receive signals from other wireless devices (e.g., UE, another base station, etc.) via one or more TRPs. For the purposes of this disclosure, in some examples, the term "TRP" may be used interchangeably with the term "base station."

[0082] For DL-AoD positioning, the positioning entity can use beam reports from the UE on received signal strength measurements for multiple downlink transmit beams to determine the angle between the UE and the transmitting base station. The positioning entity can then estimate the UE's position based on the determined angle and the known location of the transmitting base station.

[0083] Uplink-based positioning methods may include UL-TDOA and UL-AoA. UL-TDOA is similar to DL-TDOA, but is based on uplink reference signals (e.g., sounding reference signals (SRS)) transmitted by the UE. For UL-AoA positioning, one or more base stations may measure the received signal strength of one or more uplink reference signals (e.g., SRS) received from the UE on one or more uplink receive beams. The positioning entity may use the signal strength measurement and the angle of the receive beam to determine the angle between the UE and the base station. Based on the determined angle and the known location of the base station, the positioning entity may then estimate the location of the UE.

[0084] Downlink and uplink-based positioning methods may include enhanced cell ID (E-CID) positioning and multi-round trip time (RTT) positioning (also referred to as "multi-cell RTT"). In the RTT procedure, the initiator (base station or UE) transmits an RTT measurement signal (e.g., PRS or SRS) to the responder (UE or base station), and the responder transmits an RTT response signal (e.g., SRS or PRS) back to the initiator. The RTT response signal may include the difference between the ToA of the RTT measurement signal and the transmission time of the RTT response signal (referred to as the receive-transmit (Rx-Tx) time difference). The initiator may calculate the difference between the transmission time of the RTT measurement signal and the ToA of the RTT response signal (referred to as the transmit-receive (Tx-Rx) time difference). The propagation time (also referred to as "flight time") between the initiator and the responder may be calculated using the Tx-Rx and Rx-Tx time differences. Based on the propagation time and the known speed of light, the distance between the initiator and the responder may be determined. For multi-RTT positioning, the UE may perform RTT procedures with multiple base stations so that the UE's position can be determined based on the known positions of the base stations (e.g., using multilateration). RTT and multi-RTT methods may be combined with other positioning techniques (such as UL-AoA and DL-AoD) to improve position accuracy.

[0085] The E-CID positioning method can be based on radio resource management (RRM) measurements. In E-CID, the UE can report the serving cell ID and timing advance (TA), as well as the identifiers, estimated timing and signal strength of the detected neighboring base stations. The UE's position is then estimated based on this information and the known location of the base stations.

[0086] To assist the positioning operation, a location server (e.g., a location server, LMF, or SLP) may provide assistance data to the UE. For example, the assistance data may include: an identifier of the base station (or cell / TRP of the base station) from which the reference signal is measured, reference signal configuration parameters (e.g., the number of consecutive positioning subframes, the periodicity of the positioning subframes, the silent sequence, the frequency hopping sequence, the reference signal identifier, the reference signal bandwidth, etc.), and / or other parameters applicable to a specific positioning method. Alternatively, the assistance data may originate directly from the base station (e.g., in an overhead message broadcast periodically, etc.). In some cases, the UE may be able to detect neighboring network nodes without using assistance data.

[0087] In the case of OTDOA or DL-TDOA positioning procedures, the auxiliary data may further include an expected RSTD value and associated uncertainty, or a search window around the expected RSTD. In some cases, the value range of the expected RSTD may be + / -500 microseconds (μs). In some cases, when any resource used for positioning measurement is in FR1, the value range of the uncertainty of the expected RSTD may be + / -32μs. In other cases, when all resources used for positioning measurement are in FR2, the value range of the uncertainty of the expected RSTD may be + / -8μs.

[0088] The position estimate may also be referred to as a positioning estimate, a position, a fix, a position fix, a fix, etc. The position estimate may be geodetic and include coordinates (e.g., latitude, longitude, and possibly altitude), or may be municipal and include a street address, a postal address, or some other verbal description of the location. The position estimate may be further defined relative to some other known location or in absolute terms (e.g., using latitude, longitude, and possibly altitude). The position estimate may include an expected error or uncertainty (e.g., by including an area or volume within which the position is expected to be contained with a specified or default confidence level). For purposes of this disclosure, reference signals may include PRS, tracking reference signals (TRS), phase tracking reference signals (PTRS), cell-specific reference signals (CRS), CSI-RS, demodulation reference signals (DMRS), PSS, SSS, SBS, SRS, etc., depending on whether the illustrated frame structure is for uplink or downlink communication. In some examples, a set of resource elements (REs) used for transmission of PRS is referred to as a "PRS resource". A set of resource elements may span multiple PRBs in the frequency domain and one or more consecutive symbols within a time slot in the time domain. In a given OFDM symbol in the time domain, a PRS resource may occupy consecutive PRBs in the frequency domain. In other examples, a "PRS resource set" may refer to a PRS resource set used for the transmission of a PRS signal, wherein each PRS resource may have a PRS resource ID. In addition, the PRS resources in a PRS resource set may be associated with the same TRP. A PRS resource set may be identified by a PRS resource set ID and may be associated with a specific TRP (identified by a TRP ID). In addition, the PRS resources in a PRS resource set may have the same periodicity, a common muting mode configuration, and / or the same cross-slot repetition factor. The periodicity may be the time from the first repetition of the first PRS resource of the first PRS instance to the same first repetition of the same first PRS resource of the next PRS instance. For example, the periodicity may have a length selected from: 2^μ*{4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320, 640, 1280, 2560, 5120, 10240} time slots, where μ=0, 1, 2, 3. The repetition factor may have a length selected from {1, 2, 4, 6, 8, 16, 32} time slots. The PRS resource ID in a PRS resource set may be associated with a single beam (or beam ID) transmitted from a single TRP (where one TRP may transmit one or more beams). That is, each PRS resource in a PRS resource set may be transmitted on a different beam, and therefore, a "PRS resource" (or simply "resource") may also be referred to as a "beam".In some examples, a "PRS instance" or "PRS opportunity" may be an instance of a periodically repeating time window (such as a group of one or more consecutive time slots) in which a PRS is expected to be transmitted. A PRS opportunity may also be referred to as a "PRS positioning opportunity," "PRS positioning instance," "positioning opportunity," "positioning instance," "positioning repetition," or simply "opportunity," "instance," and / or "repetition," etc.

[0089] A positioning frequency layer (PFL) (which may also be referred to as a "frequency layer") may be a set of one or more PRS resource sets with the same values ​​for certain parameters across one or more TRPs. Specifically, the set of PRS source sets may have the same subcarrier spacing and cyclic prefix (CP) type (e.g., meaning that all digital schemes that support PDSCH also support PRS), the same point A, the same downlink PRS bandwidth value, the same starting PRB (and center frequency) and / or the same comb size, etc. The point A parameter may take the value of the parameter ARFCN-ValueNR (where "ARFCN" stands for "absolute radio frequency channel number") and may be an identifier / code that specifies a physical radio channel pair for transmission and reception. In some examples, the downlink PRS bandwidth may have a granularity of 4 PRBs, with a minimum value of 24 PRBs and a maximum value of 272 PRBs. In other examples, up to 4 frequency layers have been configured, and up to 2 PRS resource sets may be configured per frequency layer per TRP.

[0090] The concept of frequency layer may be similar to component carrier (CC) and BWP, where CC and BWP may be used by one base station (or macro cell base station and small cell base station) to transmit data channels, and frequency layer may be used by multiple (e.g., three or more) base stations to transmit PRS. The UE may indicate the number of frequency layers it can support when the UE sends its positioning capabilities to the network (such as during an LTE positioning protocol session). For example, the UE may indicate whether it can support one or four PFLs.

[0091] Figure 44 is a diagram illustrating an example of UE positioning based on reference signal measurements in accordance with various aspects of the present disclosure. In one example, the position of a UE 404 may be estimated based on multi-cell round trip time (multi-RTT) measurements, where a plurality of TRPs 402 may perform round trip time (RTT) measurements on signals transmitted to and received from the UE 404 to determine an approximate distance of the UE 404 relative to each of the plurality of TRPs 402. Similarly, the UE 404 may perform RTT measurements on signals transmitted to and received from the TRPs 402 to determine an approximate distance of each TRP relative to the UE 404. Then, based at least in part on the approximate distances of the UE 404 relative to the plurality of TRPs 402, a location management function (LMF) associated with the TRPs 402 and / or the UE 404 may estimate the position of the UE 404. For example, the TRP 406 may transmit at least one downlink positioning reference signal (DL-PRS) 410 to the UE 404 and may receive at least one uplink sounding reference signal (UL-SRS) 412 transmitted from the UE 404. Based at least in part on measuring the RTT 414 between the transmitted DL-PRS 410 and the received UL-SRS 412, a serving base station associated with the TRP 406 or an LMF associated with the TRP 406 may identify a location (e.g., a distance) of the UE 404 relative to the TRP 406. Similarly, the UE 404 may transmit the UL-SRS 412 to the TRP 406 and may receive the DL-PRS 410 transmitted from the TRP 406. Based at least in part on measuring the RTT 414 between the transmitted UL-SRS 412 and the received DL-PRS 410, the UE 404 or an LMF associated with the UE 404 may identify the location of the TRP 406 relative to the UE 404. The multi-RTT measurement mechanism may be initiated by the LMF associated with the TRP 406 / 408 and / or the UE 404. The TRP may configure the UL-SRS resources to the UE via radio resource control (RRC) signaling. In some examples, the UE and the TRP may report the multi-RTT measurements to the LMF, and the LMF may estimate the location of the UE based on the reported multi-RTT metrics.

[0092] In other examples, the location of the UE may be estimated based on multiple antenna beam measurements, where the downlink angle of departure (DL-AoD) and / or uplink angle of arrival (UL-AoA) of the transmission between the UE and one or more TRPs may be used to estimate the location of the UE and / or the distance of the UE relative to each TRP. For example, referring back to Figure 6, with respect to DL-AoD, UE 404 may perform reference signal received power (RSRP) measurements of a DL-PRS set 416 transmitted from a plurality of transmit beams (e.g., DL-PRS beams) of TRP 408, and UE 404 may provide the DL-PRS beam measurements to a serving base station (or to an LMF associated with a base station). Based on the DL-PRS beam measurements, the serving TRP or LMF may derive a departure azimuth (e.g., Φ) and a departure zenith angle (e.g., θ) of the DL-PRS beam of TRP 408. The serving TRP or LMF may then estimate the positioning of UE 404 relative to TRP 408 based on the departure azimuth and departure zenith angle of the DL-PRS beam. Similarly, with respect to UL-AoA, the positioning of the UE may be estimated based on UL-SRS beam measurements measured at a different TRP (such as at TRP 402). Based on the UL-SRS beam measurement, the serving base station or the LMF associated with the serving base station can derive the arrival azimuth and arrival zenith angle of the UL-SRS beam from the UE, and the serving base station or the LMF can estimate the positioning of the UE and / or the distance of the UE relative to each of the TRPs based on the arrival azimuth and arrival zenith angle of the UL-SRS beam.

[0093] Figure 5A 500A is a diagram illustrating an example of a DL-PRS transmitted from multiple TRPs according to various aspects of the present disclosure. In one example, the serving base station may configure the DL-PRS to be transmitted from one or more TRPs in one time slot or across multiple time slots. If the DL-PRS is configured to be transmitted in one time slot, the serving base station may configure the starting resource element from each of the one or more TRPs in time and frequency. If the DL-PRS is configured to be transmitted across multiple time slots, the serving base station may configure the gap between the DL-PRS time slots, the periodicity of the DL-PRS, and / or the density of the DL-PRS in the time period. The serving base station may also configure the DL-PRS to start at any physical resource block (PRB) in the system bandwidth. In one example, the system bandwidth may be in the range of from 24 to 276 PRBs, with a step size of 4 PRBs (e.g., 24, 28, 32, 36, etc.). The serving base station may transmit a DL-PRS in a PRS beam, where the PRS beam may be referred to as a "PRS resource," and the entire set of PRS beams transmitted from a TRP on the same frequency may be referred to as a "PRS resource set" or a "PRS resource set," such as in conjunction with Figure 4 As described. Figure 5A As shown, DL-PRS transmitted from different TRPs and / or from different PRS beams may be multiplexed across symbols or time slots.

[0094] In some examples, each symbol of the DL-PRS may be configured with a comb structure in frequency, where the DL-PRS from a TRP of a base station may occupy every N subcarriers. The comb value N may be configured to be 2, 4, 6, or 12. The length of the PRS within a slot may be a multiple of N symbols, and the position of the first symbol within a slot may be flexible, as long as the slot consists of at least N PRS symbols. Diagram 500A shows an example of a comb-6 DL-PRS configuration, where the pattern for DL-PRS from different TRPs may be repeated after six (6) symbols.

[0095] Figure 5B 500B is a diagram illustrating an example of a UL-SRS transmitted from a UE according to various aspects of the present disclosure. In one example, the UL-SRS from the UE may be configured with a comb-4 pattern, where the pattern for the UL-SRS may be repeated after four (4) symbols. Similarly, the UL-SRS may be configured in one SRS resource of an SRS resource set, where each SRS resource may correspond to an SRS beam, and the SRS resource set may correspond to a set of SRS resources (e.g., beams) configured for a TRP. In some examples, the SRS resources may span 1, 2, 4, 8, or 12 consecutive OFDM symbols. In other examples, the comb size for the UL-SRS may be configured to be 2, 4, or 8.

[0096] Figure 6 600 is a diagram illustrating an example of estimating the positioning of a UE based on multi-RTT measurements from multiple TRPs according to various aspects of the present disclosure. The UE 602 may be configured by a serving base station to decode DL-PRS resources 612 corresponding to and transmitted from a first TRP 604 (TRP-1), a second TRP 606 (TRP-2), a third TRP 608 (TRP-3), and a fourth TRP 610 (TRP-4). The UE 602 may also be configured to transmit a UL-SRS on a UL-SRS resource set, which may include a first SRS resource 614, a second SRS resource 616, a third SRS resource 618, and a fourth SRS resource 620, so that a serving cell (e.g., the first TRP 604, the second TRP 606, the third TRP 608, and the fourth TRP 610) and other neighboring cells may be able to measure the UL-SRS resource set transmitted from the UE 602. For multi-RTT measurements based on DL-PRS and UL-SRS, since there may be a correlation between the UE's measurement of DL-PRS and the TRP's measurement of UL-SRS, the smaller the gap between the UE's DL-PRS measurement and the UE's UL-SRS transmission, the better the accuracy of estimating the UE's positioning and / or the UE's distance relative to each TRP may be.

[0097] It should be noted that the terms "positioning reference signal" and "PRS" generally refer to specific reference signals used for positioning in NR and LTE systems. However, as used herein, the terms "positioning reference signal" and "PRS" may also refer to any type of reference signal that can be used for positioning, such as but not limited to: PRS, TRS, PTRS, CRS, CSI-RS, DMRS, PSS, SSS, SSB, SRS, UL-PRS, etc. as defined in LTE and NR. In addition, the terms "positioning reference signal" and "PRS" may refer to downlink or uplink positioning reference signals, unless otherwise indicated by the context. If it is necessary to further distinguish the type of PRS, the downlink positioning reference signal may be referred to as "DL-PRS", and the uplink positioning reference signal (e.g., SRS, PTRS used for positioning) may be referred to as "UL-PRS". In addition, for signals that can be transmitted in both uplink and downlink (e.g., DMRS, PTRS), these signals may be prepended with "UL" or "DL" to distinguish the direction. For example, "UL-DMRS" may be distinguished from "DL-DMRS".

[0098] In some scenarios, the UE may receive multiple PRS resources from multiple TRPs via one or more PFLs, where the UE may not have the ability to process all of the multiple PRS resources. Thus, the UE may apply a predefined prioritization rule to prioritize the measurement of the PRS resources. Based on the predefined prioritization rule, the UE may measure a subset of the multiple PRS resources, and the UE may skip measuring another subset of the multiple PRS resources.

[0099] Figure 7700 is a diagram illustrating example DL PRS resource prioritization according to various aspects of the present disclosure. A UE may be configured with multiple PRS resources in the assistance data of a positioning session, wherein the number of PRS resources to be processed by the UE may exceed the processing capability of the UE. In one example, the UE may assume that the DL PRS resources in the assistance data are sorted in descending order of measurement priority. For example, if the UE is configured to receive or measure DL PRS resources via multiple frequency layers (e.g., PFLs), wherein each PFL may include PRS resources transmitted from multiple TRPs, the UE may measure the DL PRS resources based on priorities associated with the multiple frequency layers (e.g., from the first frequency layer to the last frequency layer), based on priorities associated with TRPs in each PFL (e.g., from the first TRP to the last TRP in the PFL), based on priorities associated with RPS resource sets associated with each TRP (e.g., from the first PRS resource set to the last TRP resource set in the TRP), and based on priorities associated with RPS resources within each PRS resource set (e.g., from the first PRS resource in the resource set to the last PRS resource), etc.

[0100] For example, as shown in diagram 700, the UE may be configured to receive DL PRS from a first frequency layer 702 (PFL 1) and a second frequency layer 704 (PFL 2). The first frequency layer 702 may include DL PRS transmitted from a first TRP 706 and a second TRP 708, wherein the first TRP 706 may transmit PRS using first PRS resources 716 and second PRS resources 718 in a first PRS resource set 710 and using first PRS resources 720 and second PRS resources 722 in a second PRS resource set 712, and the second TRP 708 may transmit PRS using first PRS resources 724 and second PRS resources 726 in a first PRS resource set 714. Similarly, the UE may also receive DL PRS from the second frequency layer 704 via multiple TRPs, PRS resource sets, and / or PRS resources.

[0101] In one example, if the UE does not have the ability to process all configured PRS resources, the UE may be configured to receive or measure the PRS received from the first frequency layer 702 before processing the PRS in the second frequency layer 704. Similarly, if there is also a third frequency layer (PFL 3) and a fourth frequency layer (PFL 4), the UE may be configured to first receive or measure the PRS received from the first frequency layer 702, then the PRS received from the second frequency layer 704, then the PRS received from the third frequency layer, and then the PRS received from the fourth frequency layer (e.g., the PRS is processed / measured based on PFL 1>PFL 2>PFL 3>PFL 4). If the UE does not have the ability to process / measure the PRS in the frequency layer, the UE may skip measuring the PRS in the frequency layer. For example, if the UE is configured to receive the PRS via the first frequency layer 702 and the second frequency layer 704, but the UE is just able to process / measure the PRS in the first frequency layer 702, the UE may skip the PRS measurement for the second frequency layer 704.

[0102] Similarly, within a frequency layer, if the UE does not have the ability to process all PRSs in the frequency layer, the UE may prioritize its PRS measurements based on the priority associated with the TRP. For example, the UE may be configured to receive or measure the PRS received from the first TRP 706 before processing the PRS from the second TRP 708. Similarly, if there is also a third TRP (TRP 3) and a fourth TRP (TRP 4), the UE may be configured to receive or measure the PRS received from the first TRP 706, then receive or measure the PRS from the second TRP 708, then receive or measure the PRS from the third TRP, and then receive or measure the PRS from the fourth TRP (e.g., the PRS is processed / measured based on TRP 1>TRP 2>TRP 3>TRP 4 with frequency layers). If the UE does not have the ability to process / measure the PRS from a TRP, the UE may skip measuring the PRS in that TRP. For example, if the UE is configured to receive PRS via the first TRP 706 and the second TRP 708 via the first frequency layer 702, but the UE is just able to process / measure the PRS in the first TRP 706, the UE may skip the PRS measurement for the second TRP 708.

[0103] In addition, within a TRP, if the UE does not have the ability to process all PRSs in the TRP, the UE may prioritize its PRS measurements based on the priority associated with the PRS resource set. For example, the UE may be configured to receive or measure the PRS received from the first PRS resource set 710 before processing the PRS from the second PRS resource set 712. Similarly, if there is also a third PRS resource set (PRS resource set 3) and a fourth PRS resource set (PRS resource set 4), the UE may be configured to first receive or measure the PRS received from the first PRS resource set 710, then the PRS received from the second PRS resource set 712, then the PRS received from the third PRS resource set, and then the PRS received from the fourth PRS resource set (e.g., the PRS is processed / measured based on PRS resource set 1>PRS resource set 2>PRS data set 3>PRS information set 4 with a TRP). If the UE does not have the ability to process / measure the PRS in the PRS resource set, the UE may skip measuring the PRS in the PRS resource set. For example, if the UE is configured to receive PRS from the first TRP 706 via the first PRS resource set 710 and the second PRS resource set 712, but the UE is just able to process / measure the PRS in the first PRS resource set 710, the UE may skip PRS measurement for the second PRS resource set 712.

[0104] Finally, within a PRS resource set, if the UE does not have the capability to process all PRSs in the PRS resource set, the UE may prioritize its PRS measurements based on the priority associated with the PRS resource. For example, the UE may be configured to receive or measure the PRS received from the first PRS resource 716 before processing the PRS from the second PRS resource 718. Similarly, if there are also third PRS resources (PRS resource 3) and fourth PRS resources (PRS resource 4), the UE may be configured to first receive or measure the PRS received from the first PRS resource 716, then the PRS received from the second PRS resource 718, then the PRS received from the third PRS resource, and then the PRS received from the fourth PRS resource (e.g., the PRS is processed / measured based on PRS resource 1>PRS resource 2>PRS resource 3>PRS resource 4 with a PRS resource set). If the UE does not have the capability to process / measure the PRS in a PRS resource, the UE may skip measuring the PRS in that PRS resource. For example, if the UE is configured to receive PRS via the first PRS resource 716 and the second PRS resource 718 of the first PRS resource set 710 , but the UE is just able to process / measure the PRS in the first PRS resource 716 , the UE may skip PRS measurement for the second PRS resource 718 .

[0105] Therefore, if the UE is configured with multiple PRS resources via multiple frequency layers, multiple TRPs, multiple PRS resource sets, and / or multiple PRS resources, the UE may sort the frequency layers according to priority (e.g., up to four frequency layers), also sort the TRPs per frequency layer according to priority (e.g., up to sixty-four (64) TRPs per frequency layer), sort the PRS resource sets per TRP according to priority (e.g., up to two resource sets per TRP), and / or sort the PRS resources per PRS resource set (e.g., up to sixty-four (64) PRS resources per PRS resource set). That is, within the positioning frequency layer, the DL PRS resources may be sorted in descending order of priority of measurement performed by the UE, with the reference indicated by nr-DL-PRS-ReferenceInfo as the highest priority for measurement, and assuming the following priorities: (1) up to 64 dl-PRS-IDs of the frequency layer are sorted according to priority; and up to 2 DL PRS resource sets per dl-PRS-ID of the frequency layer are sorted according to priority.

[0106] In some examples, there may be measurement period specifications specified for PRS-RSTD, PRS-RSRP, and / or UE Rx-Tx time difference, which may depend on various factors, such as UE PRS processing capabilities and / or number of samples, etc. In one example, the PRS-RSTD measurement period may be calculated based on the following equation (note that similar equations may apply to PRS-RSRP and UE Rx-Tx time difference):

[0107]

[0108] may correspond to the total number of samples to be measured, where the samples may correspond to all PRS resources within the validity period, denoted as T effect,i In addition, for the last sample, the UE can use T last =T i +T available_PRS,i , where T i May correspond to reported UE capabilities related to PRS processing.

[0109] In one example, CSSF PRS,i may be a factor used to control how measurement gaps (MGs) are shared between positioning measurements and mobility (radio resource management (RRM)) measurements. If the factor is one (1), it may indicate that there is no sharing of MG instances between positioning measurements and RRM measurements. N rxbeam It can be the Rx beam scanning factor. In some examples, N rxbeam For FR2, it can be equal to eight (8), and N rxbeamFor FR1, it can be equal to (1). The factor eight (8) in the above formula can be based on the following conservative assumption: Assuming that the UE maintains a constant Rx beam within each "instance / sample group", the UE can perform up to eight Rx beam scans across eight "instances / sample groups". may be factors that take into account the PRS processing UE capability with respect to the current PFL configuration. In one example, if the UE capability is large enough, these factors may be one (1) and this factor may not contribute to latency. N sample It can be the number of samples / instances (e.g., for a PRS with a periodicity of X ms, it can be assumed that at least N sample cycles are specified). T effect,i may correspond to an effective measurement periodicity (which is the use of MGRP, T PRS,i and the UE's reported capability T i exported). For example, Where T available_PRS,i =LCM(T PRS,i ,MGRP i ), which can take into account the alignment of MG periodicity with PRS periodicity. last may be the measurement duration of the last PRS RSTD sample, which may include sampling time and processing time, T last =T i +T available_PRS,i .

[0110] If a measurement gap for PRS measurement is configured for a UE, a UE DL PRS processing capability may be defined for the UE. In one example, for the purpose of DL PRS processing capability, the duration K ms of a DL PRS symbol within a P microsecond (ms) window corresponding to the maximum PRS periodicity in the localized frequency layer may be calculated as follows: (1) Type 1 duration calculation with UE symbol-level buffering capability, K = ∑ s∈S K s ,and (2) Type 2 duration calculation with UE slot-level buffering capability, Where S may be a set of time slots based on a digital scheme for DL ​​PRS of a serving cell within a Pms window in a positioning frequency layer, which includes potential DL PRS resources taking into account actual nr-DL-PRS-ExpectedRSTD, nr-DL-PRS-ExpectedRSTD-Uncertainty provided for each pair of DL PRS resource sets.

[0111] In one example, for a Type 1 duration calculation, can be the minimum interval in ms within a time slot s that corresponds to an integer number of OFDM symbols based on the digital scheme of the DL PRS of the serving cell that covers the union of potential PRS symbols and determines the PRS symbol occupancy within time slot s, where the interval The actual nr-DL-PRS-ExpectedRSTD, nr-DL-PRS-ExpectedRSTD-Uncertainty provided for each pair of DL PRS resource sets (target and reference) may be considered. In another example, for type 2 duration calculation, μ may be the number scheme of DL PRS, and |S| may be the cardinality of set S.

[0112] Figure 8 800 is a diagram illustrating an example of a DL-PRS transmission, processing, and reporting cycle for multiple UEs in accordance with various aspects of the present disclosure. A first UE 802 ("UE 1"), a second UE 804 ("UE 2"), and a third UE 806 ("UE 3") may be configured to use a "DDDSU" frame structure 810. In one example, the frame structure 810 may be configured with a time division duplex (TDD) 30kHz SCS, where the 30kHz SCS (μ=1) may have 20 slots per frame and the slot duration may be 0.5ms. Thus, each box of the DDDSU frame structure 810 may represent a 0.5ms slot. The DDDSU frame structure 810 may include a repetition of three downlink (D) slots, one special (S) slot, and one uplink (U) slot.

[0113] In one example, the first UE 802, the second UE 804, and / or the third UE 806 may receive one or more PRSs in the first three downlink time slots of the frame and transmit SRSs in the fourth time slot. The PRSs and SRSs may be received and transmitted as part of a downlink and uplink-based positioning session, such as an RTT positioning session, respectively. The three time slots in which the PRSs are received (i.e., measured) may correspond to PRS instances. In some examples, the PRS instances may be included within a few milliseconds (e.g., 2ms) of the start of a PRS transmission, processing, and reporting cycle. The SRS transmission (for downlink and uplink-based positioning procedures) may be close to the PRS instance (e.g., in the next time slot).

[0114] As shown in diagram 800, a first UE 802 may be configured with a PRS transmission, processing, and reporting cycle 820, a second UE 804 may be configured with a PRS transmission, processing, and reporting cycle 830, and a third UE 806 may be configured with a PRS transmission, processing, and reporting cycle 840. The PRS transmission, processing, and reporting cycles 820, 830, and 840 may be repeated periodically (e.g., every 10 ms) for a certain duration. Each UE may be expected to send a positioning report (e.g., its corresponding Rx-Tx time difference measurement) at the end of its PRS transmission, processing, and reporting cycle (e.g., every 10 ms). Each UE may send its report (e.g., a configured uplink grant) on a PUSCH. For example, the first UE 802 may send its report on a PUSCH 824, the second UE 804 may send its report on a PUSCH 834, and the third UE 806 may send its report on a PUSCH 844, and so on.

[0115] In some scenarios, different UEs may be configured with their own PRS processing windows (or simply "processing windows") or PRS processing gaps (or simply "processing gaps") for processing the PRS measured in the first three time slots of the frame (e.g., determining the ToA of the PRS and / or calculating the Rx-Tx time difference measurement, etc.). For example, the first UE 802 may be configured with a processing window 822, the second UE 804 may be configured with a processing window 832, and the third UE 806 may be configured with a processing window 842, etc. In this example, the length of each processing window may be 4 ms.

[0116] In some examples, the processing window of each UE may be offset from the processing windows of other UEs, but may still be within the UE's 10 ms PRS transmission, processing, and reporting cycle. In addition, there may still be a PUSCH opportunity for reporting the UE's measurements after the processing window. Even if there is a gap between the PRS instance and the processing windows of the second UE 804 and the third UE 806, there may be a limited time between measurement and reporting due to the short length of the UE's respective PRS transmission, processing, and reporting cycles 830 and 840.

[0117] A technical advantage of configuring offset processing windows for UEs may be higher spectrum utilization. Instead of all UEs processing PRS simultaneously after a PRS instance (and SRS transmission) and thus not processing other signals, different UEs may continue to transmit and receive while other UEs do not.

[0118] In some examples, the processing window can be a time window after the time when the UE receives and measures one or more PRSs. In other words, the processing window can be a time period during which the UE processes the PRS (e.g., to determine the ToA of the PRS for Rx-Tx time difference measurement or RSTD measurement) without having to measure any other signals. Thus, the processing window can also be referred to as a time period during which the UE prioritizes the PRS over other channels, which priority may include priority over data (e.g., PDSCH), control (e.g., PDCCH), and any other reference signal. However, as Figure 8 As shown, there may be a gap between the time of measurement and the processing gap.

[0119] In one example, if Fig. 9A As shown in FIG. 900A , the processing window may be configured to be adjacent to the measurement window. Fig. 9B As shown in diagram 900B of , there may be a gap between the processing window and the measurement window. The processing window or processing gap may be different from the measurement window (or "measurement gap"). In some examples, in the processing window, there may be no retuning gap as in the measurement gap. The retuning gap may be referred to as a retuning BWP gap, where the UE may use the retuning gap to perform BWP switching (e.g., switching from one BWP to another BWP). Therefore, the UE may not change its BWP, but continue with the BWP it had before the processing window. In addition, the location server (e.g., LMF) may determine the processing window, and the UE may not specify the processing window to send an RRC request to the serving base station and wait for a reply. As a result, the processing window may reduce signaling overhead and latency. Information related to the PRS processing window may be provided in the unicast assistance data received by the UE. The processing window may be associated with one or more PFLs, one or more PRS resource sets, one or more PRS resources, or any combination thereof.

[0120] In some examples, the UE may include a request for a specific processing window in the LPP Assistance Data Request message. Alternatively, the UE may include PRS processing window information in the LPP Provide Capabilities message. For example, the UE may include a processing window request for a "strict" PRS processing situation (e.g., a situation where there is a limited time between the measured PRS instance and the measurement report). The request may include the length of time of the PRS processing window that the UE may require for a low-latency PRS processing application. For example, for a PRS instance with "X" PRS resource sets, resources, or symbols, the UE may require 4ms of processing time. The location server may use this recommendation to send assistance data associated with a specific PRS processing window to the UE.

[0121] The processing window information configured to the UE and / or recommended by the UE may include: (1) an offset relative to: (a) the start or offset of a PRS instance (e.g., Figure 8 The processing window of the second UE 804 in FIG. 8 is offset by 4 ms from the start of the PRS instance), (b) the end of the PRS instance (e.g., Figure 8 ms from the start of the PRS instance), (c) a PRS resource offset, (d) a PRS resource set offset, and / or (e) a slot, subframe, or frame boundary (e.g., Figure 8 The processing window of the second UE 804 in the example embodiment may be 4.5 ms offset from the start of the frame); (2) the length and / or end time of the processing window; (3) whether the processing window is per UE, per band, per band combination (BC), per frequency range (e.g., FR1 or FR2), whether the processing window affects LTE; and / or (4) how many PRS resources, resource sets, or instances can be processed within a processing window of this length. In some cases, the location of the start / offset of the processing window may depend on the UE ID.

[0122] To configure a processing window for a UE, a location server (e.g., LMF) may first send an on-demand PRS configuration and a suggestion or recommendation or a request or request for a processing window for the UE to a serving base station of the UE. Note that the location server may not need to send the requested processing window at the same time as the on-demand PRS configuration (e.g., in the same message). The serving base station may then send a response to the location server. The response may be an acceptance of the requested processing window or a configuration of a different processing window. The location server then sends assistance data for the positioning session to the UE. The assistance data includes the PRS configuration and the associated processing window.

[0123] In some cases, the UE may utilize an autonomous processing window (i.e., autonomous PRS prioritization). In such cases, after a PRS instance, if no measurement gap is configured, the UE may drop or ignore all other traffic for a certain period of time without notifying the serving base station. In one aspect, there may be a maximum window that allows the UE to perform these autonomous PRS prioritizations. As an example, the UE may expect to complete PRS processing within "X" ms (e.g., 6 ms) after the end of a PRS instance, and within this "X" ms, the UE may select a period of "Y" ms (where "Y" is less than "X", such as 4 ms) during which the UE autonomously prioritizes PRS over other channels. During this window, it is up to the UE to decide whether to drop or ignore any other channels and processes (e.g., CSI processes) - the serving base station will not refrain from transmitting to the UE.

[0124] The UE may be configured to measure one or more neighboring cells, signals, and / or other carrier components from time to time. For example, the UE may measure signals transmitted from a neighboring cell while communicating with a serving cell. In some scenarios, if the neighboring cell and the serving cell operate at different frequencies and / or are based on different radio access technologies (RATs), the UE may be specified to suspend communication (e.g., Tx / Rx) with the serving cell to re-tune its RF module to adopt a different frequency and / or RAT, and the UE may resume connection with the serving cell after a certain duration.

[0125] In some examples, the duration that the UE suspends its communications with the serving cell (e.g., to measure inter-frequency neighbors and / or other RAT neighbors) may be referred to as a radio resource management (RRM) measurement gap (MG). Fig.10 1000 is a diagram illustrating an example RRM measurement gap according to various aspects of the present disclosure. A UE 1002 may receive a configuration for one or more RRM MGs 1006 (or an RRM MG mode configuration for one or more RRM MGs 1006) from a base station 1004, wherein the UE 1002 may use the one or more RRM MGs 1006 to re-tune its RF module to adapt to different frequencies and / or RATs, etc. For some networks (e.g., LTE), the length of each of the one or more RRM MGs 1006 may be fixed so that at least one synchronization signal (e.g., PSS and / or SSS) may be included within one RRM MG. For example, if the synchronization signal is transmitted with a periodicity of five (5) ms, the length of each of the one or more RRM MGs 1006 may be configured to be six (6) ms, thereby allowing a 0.5 ms re-tune of the RF module at the beginning and end of the RRM MG. For some other networks (e.g., 5GNR), the length of each RRM MG in one or more RRM MGs 1006 may be configurable / flexible. For example, the length of the RRM MG may be 1.5 ms, 3 ms, 3.5 ms, 4 ms, 5.5 ms, or 6 ms, etc., and the repetition period between the RRM MGs in one or more RRM MGs 1006 may be 20 ms, 40 ms, 80 ms, and / or 160 ms, etc. The base station 1004 may configure the RRM MG mode for the UE 1002 via RRC signaling, such as by using the MeasGapConfig information element (IE) within the MeasConfig IE of the RRC. The configuration may include two parts, wherein the first part may specify the control setup / release of the RRM MG, and the second part may specify the RRM MG configuration and control setup / release.

[0126] In some scenarios, such as Fig.11As shown in diagram 1100 of , if UE 1002 receives assistance data (AD) for positioning, base station 1004 may transmit one or more PRS 1008 to UE 1002 for measurement and processing by UE 1002 (e.g., measuring DL RSTD, DL PRS RSRP, and / or UE Rx-Tx time difference, etc.). In some examples, UE 1002 may have been configured with one or more RRM MGs 1006 by base station 1004 (e.g., via RRC), where UE 1002 may be aware of RRM MG scheduling and utilization of RRM MGs. Therefore, UE 1002 may also be aware of the amount of processing (e.g., percentage) available for one or more RRM MGs 1006 based on the measurement objects configured for one or more RRM MGs 1006. In addition, UE 1002 may also be aware of PRS processing utilization and / or its PRS processing capacity (e.g., the amount of time and / or resources used to process PRS). In some examples, RRM MG scheduling may be higher compared to PRS periodicity. For example, RRM MG may have a periodicity of 40 ms and 80 ms, while PRS periodicity may be approximately 160 ms, 320 ms, or greater.

[0127] Various aspects presented herein can improve the performance and efficiency of UE positioning sessions by reducing the number of PRS processing gaps requested by the UE. Various aspects presented herein can enable the UE to utilize one or more RRMMGs to process PRS based on one or more conditions so that the UE can process the PRS without requesting a processing gap for the PRS from a serving base station.

[0128] In one aspect of the present disclosure, based at least in part on the percentage or amount of UE processing available in one or more RRM MGs, the UE may determine whether there is sufficient processing availability in the one or more RRM MGs to process one or more PRSs received from the base station (e.g., based on the processing specified for PRS measurement). Then, if the UE determines that the processing availability in the one or more RRM MGs is sufficient to process the one or more PRSs, the UE may process the one or more PRSs during the one or more RRM MGs. In addition, the UE may be restrained from processing the one or more PRSs outside of the one or more RRM MGs, for example, the UE may be configured to hold the PRS measurement data and wait for the one or more RRM MGs to arrive, and then process the PRS measurement data. In some examples, the UE may use multiple RRM MGs to process the PRS measurement data for one PRS measurement opportunity. Therefore, the UE may also be configured not to request a processing gap for the one or more PRSs from the base station.

[0129] On the other hand, if the UE determines that the processing availability in one or more RRM MGs is insufficient to process one or more PRSs, the UE may be configured to request a PRS processing gap for processing one or more PRSs from the base station. The UE may then maintain the PRS measurement data, wait for the arrival of one or more RRM MGs and the requested PRS processing gap, and then process the PRS measurement data. In some examples, the UE may use multiple RRM MGs and / or PRS processing gaps to process PRS measurement data for one PRS measurement opportunity. In another example, the UE may also request the base station to align the PRS processing gap with the RRM MG so that the UE may process the PRS measurement data uninterruptedly via the RRM MG and the PRS measurement gap. In other words, the PRS processing gap may be aligned with an existing RRM MG or may be independently scheduled.

[0130] Fig.12 1200 is a communication flow illustrating an example of a UE utilizing an RRM MG to process a PRS according to various aspects of the present disclosure. The numbers associated with the communication flow 1200 do not specify a particular time sequence and are only used as a reference for the communication flow 1200.

[0131] At 1210, UE 1202 may receive a configuration for one or more RRM MGs 1206 (or an RRM MG mode for one or more RRM MGs 1206) from base station 1204, wherein UE 1202 may use one or more RRM MGs 1206 to re-tune its RF module to adopt a different frequency and / or RAT, etc.

[0132] At 1212, the UE 1202 may receive one or more PRSs 1208 from the base station 1204. The one or more PRSs 1208 may be associated with a UE positioning session (e.g., configured by the LMF), and the UE 1202 may receive the one or more PRSs 1208 at least before some of the one or more RRM MGs 1206, such as shown at 1220.

[0133] At 1214, the UE 1202 may identify whether the processing availability of the UE 1202 during the one or more RRM MGs 1206 is sufficient to process the one or more PRSs 1208. For example, if the UE 1202 is using 25% (e.g., based on CPU processing volume, amount of time, etc.) of its available processing resources during the one or more RRM MGs 1206 (e.g., for RF retuning and / or neighbor cell measurements, etc.), the UE 1202 may have 75% of its available processing resources left for other tasks. The UE 1202 may also determine the amount of processing resources designated for processing the one or more PRSs 1208. For example, the UE 1202 may be designated to use 60% of its available processing resources to process the one or more PRSs 1208.

[0134] At 1216, based at least in part on whether there is sufficient processing availability during one or more RRM MGs 1206 to process one or more PRSs 1208, the UE 1202 may determine whether to process one or more PRSs 1208 during one or more RRM MGs 1206 and whether to request at least one PRS processing gap from the base station 1204.

[0135] In one aspect of the present disclosure, if the UE 1202 determines that there is sufficient processing availability to process one or more PRSs 1208 during one or more RRM MGs 1206, the UE 1202 may process the one or more PRSs 1208 during the one or more RRM MGs 1206 without requesting a PRS processing gap (e.g., or an additional time gap) from the base station 1204. For example, Fig.13 As shown in diagram 1300 of , UE 1202 may process one or more PRS 1208 during one or more RRM MGs 1206, such as shown at 1302. In addition, UE 1202 may be restrained from processing one or more PRS 1208 outside of one or more RRM MGs 1206, for example, UE 1202 may be configured to save PRS measurement data for one or more PRS 1208 and wait for one or more RRM MGs 1206 to arrive, and then process the PRS measurement data during one or more RRM MGs 1206, such as shown at 1304. In some examples, UE 1202 may use more than one RRM MG to process PRS measurement data for one PRS measurement opportunity. Therefore, when there is sufficient processing availability to process one or more PRS 1208 during one or more RRM MGs 1206, the UE may not specify or request a PRS processing gap or additional processing gap from base station 1204.

[0136] In another aspect of the disclosure, if the UE 1202 determines that there is insufficient processing availability to process one or more PRSs 1208 during one or more RRM MGs 1206, as shown at 1218, the UE 1202 may be configured to request at least one PRS processing gap 1222 (or additional time gap) from the base station 1204 for processing the one or more PRSs 1208. In response, as shown at 1224, the base station 1204 may configure the at least one PRS processing gap 1222 for the UE 1202.

[0137] Then, if Fig.14A and Fig. 14B As shown in diagrams 1400A and 1400B of , the UE 1202 may store PRS measurement data for one or more PRSs 1208, wait for one or more RRM MGs 1206 and the requested PRS processing gap 1222 to arrive, and then process the PRS measurement data during the one or more RRM MGs 1206 and the requested PRS processing gap 1222. Similarly, in some scenarios, the UE 1202 may use multiple RRM MGs and / or multiple PRS processing gaps to process PRS measurement data for one PRS measurement opportunity. In addition, the UE 1202 may be restrained from processing one or more PRSs 1208 outside of the one or more RRM MGs 1206 and outside of the PRS processing gap 1222.

[0138] In one example, UE 1202 may also request base station 1204 to align PRS processing gaps 1222 with one or more RRMMGs 1206, such as Fig. 14B Thus, UE 1202 may process PRS measurement data uninterruptedly via one or more RRM MGs 1206 (or some of one or more RRM MGs 1206) and PRS measurement gaps 1222. In another example, as Fig.14A As shown at 1402, the PRS processing gap 1222 may be independently scheduled, may not be aligned with one or more RRM MGs 1206, may overlap with at least one of the one or more RRM MGs 1206, etc.

[0139] Thus, aspects presented herein may improve resource usage and performance associated with a UE positioning session by enabling the UE to utilize at least a portion of an RRM MG to process PRS, thereby effectively reducing the number of PRS processing gaps specified by the UE for processing PRS.

[0140] Fig.151500 is a flow chart of a method of wireless communication. The method may be performed by a UE or a component of a UE (e.g., UE 104, 350, 404, 602, 802, 804, 806, 1002, 1202; device 1702; a processing system, which may include memory 360 and may be the entire UE 350, or a component of the UE 350, such as TX processor 368, RX processor 356 and / or controller / processor 359). The method may enable the UE to process PRS using one or more RRM MGs based on one or more conditions, so that the UE may process the PRS without requesting a processing gap for the PRS from a serving base station.

[0141] At 1502, a device may receive a first configuration for at least one RRM measurement gap, such as in conjunction with Fig.12 For example, at 1210, UE 1202 may receive configurations for one or more RRM MGs 1206 from base station 1204 via an RRC message. Receipt of a first configuration for at least one RRM measurement gap may be, for example, by Fig.17 The RRM measurement gap processing component 1740 and / or the receiving component 1730 of the device 1702 in the embodiment can be performed. In some examples, the duration of each RRM measurement gap in the at least one RRM measurement gap can be between 40 milliseconds and 80 milliseconds.

[0142] At 1504, the UE may receive one or more PRSs prior to at least one RRM measurement gap, such as in conjunction with Fig.12 For example, at 1212, UE 1202 may receive one or more PRS 1212 prior to one or more RRM MGs 1206. The reception of the one or more PRS may be performed by, for example Fig.17 The PRS measurement component 1742 and / or the receiving component 1730 of the device 1702 may be performed.

[0143] In one example, one or more PRSs may be received from at least one TRP. Similarly, a first configuration for at least one RRM measurement gap may be received from at least one TRP.

[0144] At 1506, the UE may calculate the processing availability of the UE during at least one RRM measurement gap based at least in part on the UE capabilities of the UE, such as in conjunction with Fig.12 The calculation of processing availability can be done by, for example Fig.17 The processing availability calculation component 1748 of the device 1702 is executed.

[0145] At 1508, the UE may calculate an amount of resources designated for processing one or more PRSs based at least on a PRS processing capability associated with the UE, such as in conjunction with Fig.12 The amount of resources designated for processing one or more PRSs may be calculated by, for example Fig.17 The PRS resource calculation component 1750 of the device 1702 is executed.

[0146] At 1510, the UE may identify whether the UE's processing availability during at least one RRM measurement gap is sufficient to process one or more PRSs, such as in conjunction with Fig.12 For example, at 1214, UE 1202 may identify whether the processing availability of UE 1202 during RRM MG 1206 is sufficient to process PRS 1208. The identification of whether the processing availability of the UE during at least one RRM measurement gap is sufficient to process one or more PRSs may be determined by, for example Fig.17 The processing availability determination component 1744 of the device 1702 is executed.

[0147] In one example, to identify whether the processing availability of the UE during at least one RRM measurement gap is sufficient to process one or more PRSs, the UE may calculate a percentage of the processing availability of the UE during at least one RRM measurement gap based on one or more measurement objects configured for the at least one RRM measurement gap.

[0148] At 1512, the UE may process the one or more PRSs, wherein: in response to processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap; and in response to a lack of processing availability of the UE sufficient to process the one or more PRSs during the at least one RRM measurement gap, the one or more PRSs are processed at least partially outside of the at least one RRM measurement gap, such as in conjunction with Fig.12 For example, at 1216, based on whether the processing availability of UE 1202 during RRM MG 1206 is sufficient to process PRS 1208, UE 1202 may process PRS 1208 during RRM MG 1206 or outside of RRM MG 1206. Processing of one or more PRSs may be performed by, for example Fig.17 In one example, in response to receiving one or more PRSs at a PRS measurement window that does not overlap with at least one RRM measurement gap (e.g., one or more PRSs are at different locations from at least one RRM measurement gap), the UE may continue to process the one or more PRSs outside of the at least one RRM measurement gap.

[0149] At 1514, the UE may refrain from requesting a PRS processing gap from the base station based on the UE's processing availability during at least one RRM measurement gap being sufficient to process one or more PRSs, such as in conjunction with Fig.12 The suppression of the request PRS processing gap may be performed by, for example Fig.17 The processing gap request component 1752 of the device 1702 is executed.

[0150] At 1516, the UE may transmit a request for at least one PRS processing gap to the base station based on the at least one RRM measurement gap being insufficient to process one or more PRSs, such as in conjunction with Fig.12 For example, at 1218, UE 1202 may transmit a request for at least one PRS processing gap 1222 to base station 1204. The transmission of the request for at least one PRS processing gap may be performed by, for example, Fig.17 The processing gap request component 1752 and / or the transmitting component 1734 of the device 1702 in the embodiment are executed.

[0151] At 1518, the UE may receive a second configuration for at least one PRS processing gap from the base station based on the request, such as in conjunction with Fig.12 For example, at 1224, UE 1202 may receive a configuration for configuring at least one PRS processing gap 1222 from base station 1204. Receipt of a second configuration for at least one PRS processing gap may be performed by, for example Fig.17 The processing gap processing component 1754 and / or the receiving component 1730 of the device 1702 are executed.

[0152] In one example, the request for at least one PRS processing gap may further instruct the base station to align the at least one PRS processing gap with the at least one RRM measurement gap, and the second configuration may align the at least one PRS processing gap with the at least one RRM measurement gap.

[0153] Fig.16 1600 is a flow chart of a method of wireless communication. The method may be performed by a UE or a component of a UE (e.g., UE 104, 350, 404, 602, 802, 804, 806, 1002, 1202; device 1702; a processing system, which may include memory 360 and may be the entire UE 350, or a component of the UE 350, such as TX processor 368, RX processor 356 and / or controller / processor 359). The method may enable the UE to process PRS using one or more RRM MGs based on one or more conditions, so that the UE may process the PRS without requesting a processing gap for the PRS from a serving base station.

[0154] At 1602, the UE may receive a first configuration for at least one RRM measurement gap, such as in conjunction with Fig.12 For example, at 1210, UE 1202 may receive a configuration for one or more RRM MGs 1206 from base station 1204 via an RRC message. Receipt of a first configuration for at least one RRM measurement gap may be, for example, by Fig.17 The RRM measurement gap processing component 1740 and / or the receiving component 1730 of the device 1702 in the embodiment can be performed. In some examples, the duration of each RRM measurement gap in the at least one RRM measurement gap can be between 40 milliseconds and 80 milliseconds.

[0155] At 1604, the UE may receive one or more PRSs prior to at least one RRM measurement gap, such as in conjunction with Fig.12 For example, at 1212, UE 1202 may receive one or more PRS 1212 prior to one or more RRM MGs 1206. The reception of the one or more PRS may be performed by, for example Fig.17 The PRS measurement component 1742 and / or the receiving component 1730 of the device 1702 may be performed.

[0156] In one example, one or more PRSs may be received from a base station or at least one TRP. Similarly, a first configuration for at least one RRM measurement gap may be received from a base station or at least one TRP.

[0157] In another example, the UE may calculate the processing availability of the UE during at least one RRM measurement gap based at least in part on the UE capabilities of the UE, such as in conjunction with Fig.12 The calculation of processing availability can be done by, for example Fig.17 The processing availability calculation component 1748 of the device 1702 is executed.

[0158] In another example, the UE may calculate the amount of resources designated for processing one or more PRSs based at least on a PRS processing capability associated with the UE, such as in conjunction with Fig.12 The amount of resources designated for processing one or more PRSs may be calculated by, for example Fig.17 The PRS resource calculation component 1750 of the device 1702 is executed.

[0159] At 1610, the UE may identify whether the UE's processing availability during at least one RRM measurement gap is sufficient to process one or more PRSs, such as in conjunction with Fig.12For example, at 1214, UE 1202 may identify whether the processing availability of UE 1202 during RRM MG 1206 is sufficient to process PRS 1208. The identification of whether the processing availability of the UE during at least one RRM measurement gap is sufficient to process one or more PRSs may be determined by, for example Fig.17 The processing availability determination component 1744 of the device 1702 is executed.

[0160] In one example, to identify whether the processing availability of the UE during at least one RRM measurement gap is sufficient to process one or more PRSs, the UE may calculate a percentage of the processing availability of the UE during at least one RRM measurement gap based on one or more measurement objects configured for the at least one RRM measurement gap.

[0161] At 1612, the UE may process the one or more PRSs, wherein: in response to processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap; and in response to a lack of processing availability of the UE sufficient to process the one or more PRSs during the at least one RRM measurement gap, the one or more PRSs are processed at least partially outside of the at least one RRM measurement gap, such as in conjunction with Fig.12 For example, at 1216, based on whether the processing availability of UE 1202 during RRM MG 1206 is sufficient to process PRS 1208, UE 1202 may process PRS 1208 during RRM MG 1206 or outside of RRM MG 1206. Processing of one or more PRSs may be performed by, for example Fig.17 In one example, in response to receiving one or more PRSs at a PRS measurement window that does not overlap with at least one RRM measurement gap (e.g., the one or more PRSs are at different locations from the at least one RRM measurement gap), the UE may continue to process the one or more PRSs outside of the at least one RRM measurement gap.

[0162] In one example, the UE may refrain from requesting a PRS processing gap from the base station based on the UE's processing availability being sufficient to process one or more PRSs during at least one RRM measurement gap, such as in conjunction with Fig.12 The suppression of the request PRS processing gap may be performed by, for example Fig.17 The processing gap request component 1752 of the device 1702 is executed.

[0163] In another example, the UE may transmit a request for at least one PRS processing gap to the base station based on at least one RRM measurement gap being insufficient to process one or more PRSs, such as in conjunction with Fig.12 For example, at 1218, UE 1202 may transmit a request for at least one PRS processing gap 1222 to base station 1204. The transmission of the request for at least one PRS processing gap may be performed by, for example, Fig.17 The processing gap request component 1752 and / or the transmitting component 1734 of the device 1702 in the embodiment are executed.

[0164] In another example, the UE may receive a second configuration for at least one PRS processing gap from the base station based on the request, such as in conjunction with Fig.12 For example, at 1224, UE 1202 may receive a configuration for configuring at least one PRS processing gap 1222 from base station 1204. Receipt of a second configuration for at least one PRS processing gap may be performed by, for example Fig.17 The processing gap processing component 1754 and / or the receiving component 1730 of the device 1702 are executed.

[0165] In another example, the request for at least one PRS processing gap may further instruct the base station to align the at least one PRS processing gap with the at least one RRM measurement gap, and the second configuration may align the at least one PRS processing gap with the at least one RRM measurement gap.

[0166] Fig.171700 is a diagram illustrating an example of a hardware implementation for a device 1702. The device 1702 may be a UE, a component of a UE, or may implement UE functionality. In some aspects, the device 1702 may include a baseband processor 1704 (also referred to as a modem) coupled to at least one transceiver 1722 (e.g., one or more RF transceivers and / or antennas). The at least one transceiver 1722 may be associated with or include a receiving component 1730 and / or a transmitting component 1734. In some aspects, the device 1702 may also include one or more subscriber identity modules (SIM) cards 1720, an application processor 1706 coupled to a secure digital (SD) card 1708 and a screen 1710, a Bluetooth module 1712, a wireless local area network (WLAN) module 1714, a global positioning system (GPS) module 1716, or a power supply 1718.

The baseband processor 1704 also includes a receiving component 1730, a communication manager 1732, and a transmitting component 1734. In a non-limiting example, the receiving component 1730 and the transmitting component 1734 may include at least one transceiver and / or at least one antenna subsystem. The communication manager 1732 includes one or more of the illustrated components.

[0168] The apparatus may include executing Fig.15 and Fig.16 Each box in the flowchart of the algorithm is an additional component. Therefore, Fig.15 and Fig.16 Each block in the flowchart of can be performed by a component, and the device may include one or more of those components. These components can be one or more hardware components that are specifically configured to perform the process / algorithm, implemented by a processor configured to perform the process / algorithm, stored in a computer-readable medium so as to be implemented by a processor, or some combination thereof.

[0169] As shown, the device 1702 may include various components configured for various functions. In one configuration, the device 1702 (and specifically the baseband processor 1704) includes means for receiving a first configuration for at least one RRM measurement gap (e.g., an RRM measurement gap processing component 1740 and / or a receiving component 1730). The device 1702 includes means for receiving one or more PRSs prior to at least one RRM measurement gap (e.g., a PRS measurement component 1742 and / or a receiving component 1730). The device 1702 includes means for identifying whether the processing availability of the UE during the at least one RRM measurement gap is sufficient to process the one or more PRSs (e.g., a processing availability determination component 1744). The device 1702 includes means for processing one or more PRSs, wherein in response to a processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap, and in response to a lack of processing availability of the UE during the at least one RRM measurement gap sufficient to process the one or more PRSs, the one or more PRSs are processed at least in part outside of the at least one RRM measurement gap (e.g., a PRS processing component 1746 and / or a receiving component 1730). The device 1702 includes means for calculating the processing availability of the UE during the at least one RRM measurement gap based at least in part on a UE capability of the UE (e.g., a processing availability calculation component 1748). The device 1702 includes means for calculating an amount of resources designated for processing the one or more PRSs based at least on a PRS processing capability associated with the UE (e.g., a PRS resource calculation component 1750). The device 1702 includes means for refraining from requesting a PRS processing gap from a base station based on the processing availability of the UE during the at least one RRM measurement gap being sufficient to process the one or more PRSs (e.g., a processing gap request component 1752). The device 1702 includes means for transmitting a request for at least one PRS processing gap to a base station based on at least one RRM measurement gap being insufficient to process one or more PRSs (e.g., processing gap requesting component 1752 and / or transmitting component 1734). The device 1702 includes means for receiving a second configuration for at least one PRS processing gap from the base station based on the request (e.g., processing gap processing component 1754 and / or receiving component 1730).
