Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. patent application serial number 17 / 930,984, filed on September 9, 2022, entitled “MANAGEMENT OF POSITION REFERENCE SIGNALS AND MEASUREMENT GAPS,” 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 a user equipment (UE) that manages position reference signals (PRS) and measurement gaps (MGs). 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 a city, country, region, and even global level. An example telecommunication standard is 5G New Radio (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. 5GNR 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 4G Long Term Evolution (LTE) standards. 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. Summary of the invention

[0006] A simplified summary of one or more aspects is presented below to provide a basic understanding of these aspects. This summary is not an extensive review of all contemplated aspects. This summary neither identifies the key or important elements of all aspects, nor describes the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to a more detailed description presented later.

The apparatus may obtain a first indication of a first measurement gap resource associated with a first time period. The apparatus may receive a PRS set during a position reference signal (PRS) opportunity. The first portion of the PRS opportunity may not overlap with any portion of the first time period. The apparatus may measure the PRS set at the first portion of the PRS opportunity based on at least one of (i) the first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with a second time period overlapping with the first portion of the PRS opportunity, or (iii) a positioning processing window (PPW) associated with a third time period overlapping with the first portion of the PRS opportunity.

[0028] A user equipment (UE) may be scheduled to perform positioning reference signal (PRS) measurements and other measurements that may conflict with performing PRS measurements. In one aspect, a time period during which a UE may be scheduled to measure a PRS set (i.e., a PRS opportunity) may conflict with a time period during which a UE may be scheduled to measure a signal using a measurement gap resource (i.e., a measurement gap opportunity). In another aspect, a measurement gap opportunity may allow measurement of a signal such as a synchronization signal block (SSB) during a measurement gap opportunity, but may not allow measurement of a PRS during the same measurement gap opportunity. A UE with a PRS schedule that conflicts with a measurement gap schedule may be configured to resolve such conflicts in a timely manner by measuring a PRS set during a non-colliding time period, sending a request for a positioning processing window (PPW) for measuring a PRS set, or allocating a new measurement gap resource for measuring a PRS set.

[0029] In an aspect, a UE may obtain a first indication of a first measurement gap resource associated with a first time period. The UE may receive a PRS set during a PRS opportunity. The first portion of the PRS opportunity may not overlap with any portion of the first time period. The UE may measure the PRS set at the first portion of the PRS opportunity based on at least one of (i) a first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with a second time period overlapping with the first portion of the PRS opportunity, or (iii) a PPW associated with a third time period overlapping with the first portion of the PRS opportunity.

[0030] The specific embodiments described below in conjunction with the accompanying drawings are descriptions of various configurations and do not represent the only configurations in which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the specific embodiments include specific details. However, these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0031] Several aspects of telecommunication systems are presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] As an example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system", which includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic components, 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 referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.

[0033] Thus, in one or more example aspects, specific implementations and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available media that can be accessed by a computer. For example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0034] Although various aspects, specific implementations and / or use cases are described in this application by the illustration of some examples, additional or different aspects, specific implementations and use cases may be generated in many different arrangements and scenarios. The various aspects, specific implementations and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes and packaging arrangements. For example, various aspects, specific implementations and / or use cases can be generated via integrated chip specific implementations and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, artificial intelligence (AI) enabled devices, etc.). Although some examples may or may not be specifically for use cases or applications, the described examples may have a wide range of applicability. Various aspects, specific implementations and / or use cases may be in the range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregated, distributed or original equipment manufacturer (OEM) devices or systems in conjunction with one or more technologies herein. In some actual settings, the equipment combined with the various aspects and features described may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.) The various techniques described herein can be practiced in a wide variety of devices of various sizes, shapes, and configurations, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc.

[0035] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or a network equipment (such as a base station (BS), or one or more units (or one or more components) that perform base station functionality can be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as an aggregated base station (also referred to as an independent BS or a monolithic BS) or a decomposed base station.

[0036] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0037] Base station operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configuration such as that initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0038] Figure 1 1 is a diagram 100 illustrating an example of a wireless communication system and an access network. The illustrated wireless communication system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that may communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units, such as a near real-time (near RT) RAN intelligent controller (RIC) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework 105, or both. The CU 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RU 140 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0039] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interfaces of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive signals or send signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive and / or send signals to one or more of the other units via a wireless transmission medium.

[0040] In some aspects, CU 110 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 110. CU 110 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 110 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 110 may be implemented to communicate with DU 130 for network control and signaling.

[0041] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 140. In some aspects, DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to a functional split such as those defined by 3GPP. In some aspects, DU 130 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0042] The lower layer functionality may be implemented by one or more RUs 140. In some deployments, the RU 140 controlled by the DU 130 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, real-time and non-real-time aspects of control plane communications and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration may enable the DU 130 and CU 110 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0043] The SMO framework 105 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 190) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some specific implementations, the SMO framework 105 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 111) via the O1 interface. Additionally, in some specific implementations, the SMO framework 105 may communicate directly with one or more RUs 140 via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .

[0044] The non-RT RIC 115 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 125. The non-RT RIC 115 may be coupled to or in communication with the near-RT RIC 125 (such as via an A1 interface). The near-RT RIC 125 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 110, one or more DUs 130, or both, and the O-eNB with the near-RT RIC 125.

[0045] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 125 and may be received from a non-network data source or from a network function at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via creation of RAN management policies (such as A1 policies).

[0046] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Therefore, the base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component is indicated by a dotted line to indicate that each component may be included in the base station 102 or may not be included in the base station). The base station 102 provides an access point to the core network 120 for the UE 104. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). Small cells include femto cells, pico cells, and micro cells. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to RU 140 and / or downlink (DL) (also known as forward link) transmission from RU 140 to UE 104. The communication link may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link may be through one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum of up to Y MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.) bandwidth. These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL). Component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0047] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL wireless wide area network (WWAN) spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0048] The wireless communication system may also include a Wi-Fi AP 150 that communicates with a UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in a 5 GHz unlicensed spectrum, etc. When communicating in an unlicensed spectrum, the UE 104 / AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0049] 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 as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and articles. 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).

[0050] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-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 (71GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0051] In view of the above, unless otherwise specified, if the term "6 GHz or less" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specified, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0052] The base station 102 and the UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. The base station 102 may send a beamformed signal 182 to the UE 104 in one or more transmit directions. The UE 104 may receive the beamformed signal from the base station 102 in one or more receive directions. The UE 104 may also send a beamformed signal 184 to the base station 102 in one or more transmit directions. The base station 102 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 102 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of the base station 102 / UE 104. The transmit direction and receive direction of the base station 102 may be the same or may not be the same. The transmit direction and receive direction of the UE 104 may be the same or may not be the same.

[0053] The base station 102 may include and / or be referred to as a gNB, a Node B, an eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit receive point (TRP), a network node, a network entity, a network equipment, or some other suitable term. The base station 102 may be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, an aggregated (monolithic) base station with a baseband unit (BBU) (including a CU and a DU) and a RU, or as a decomposed base station including one or more of a CU, a DU, and / or a RU. A set of base stations that may include decomposed base stations and / or aggregated base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0054] The core network 120 may include an access and mobility management function (AMF) 161, a session management function (SMF) 162, a user plane function (UPF) 163, a unified data management (UDM) 164, one or more location servers 168, and other functional entities. AMF 161 is a control node that handles signaling between UE 104 and core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identity handling, access authorization, and subscription management. One or more location servers 168 are illustrated as including a gateway mobile location center (GMLC) 165 and a location management function (LMF) 166. However, in general, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, LMF 166, position determination entity (PDE), serving mobile location center (SMLC), mobile positioning center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. LMF 166 receives measurement and assistance information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may determine the location of UE 104 using one or more positioning methods. Positioning UE 104 may involve signal measurements, position estimation, and optional speed calculation based on these measurements. Signal measurements may be performed by UE 104 and / or serving base station 102. The measured signals may be based on a satellite positioning system (SPS) 170 (e.g., one or more of a global navigation satellite system (GNSS), a global positioning system (GPS), a non-terrestrial network (NTN), or other satellite positioning / positioning systems), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., an atmospheric pressure sensor, a motion sensor), an NR enhanced cell ID (NR E-CID) method, NR signals (e.g., multi-round trip time (multi-RTT), DL angle of departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning), and / or one or more of other systems / signals / sensors.

[0055] Examples of UE 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the UEs in UE 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as stations, mobile stations, subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, user agents, mobile clients, clients, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more supporting devices, such as in a device cluster arrangement. One or more of these devices may access the network collectively and / or individually.

[0056] Reference again Figure 1 In certain aspects, the UE 104 may have a PRS and measurement gap (MG) management component 198 configured to obtain a first indication of a first measurement gap resource associated with a first time period. The PRS and MG management component 198 may be configured to receive a PRS set during a PRS opportunity. The first portion of the PRS opportunity may not overlap with any portion of the first time period. The PRS and MG management component 198 may be configured to measure the PRS set at the first portion of the PRS opportunity based on at least one of (i) a first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with a second time period overlapping with the first portion of the PRS opportunity, or (iii) a PPW associated with a third time period overlapping with the first portion of the PRS opportunity. Although the following description may focus on managing PRS and MG resources, the concepts described herein may be applicable to other areas for managing disparate scheduled wireless signals, such as wireless signals from a serving cell and a non-serving cell or wireless signals from a terrestrial network node and a non-terrestrial network node.

[0057] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2DFIG280 is a diagram illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL, or may be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A , Figure 2C In the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are full DL and full UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE is configured with the slot format through the received slot format indicator (SFI) (dynamically configured through DL control information (DCI) or semi-statically / statically configured through radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0058] FIG. 2A to FIG. 2D The frame structure is illustrated, and various aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 subframes of equal size (1ms). Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For a normal CP, each time slot may include 14 symbols, and for an extended CP, each time slot may include 12 symbols. The symbol on the DL may be a CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) extended OFDM (DFT-s-OFDM) symbol (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 in a subframe is based on the CP and the parameter set. The parameter set defines the subcarrier spacing (SCS) (see

[0059] Table 1). Symbol length / duration can be scaled with 1 / SCS.

[0060]

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

[0062] For normal CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Thus, for normal CP and parameter set μ, there are 14 symbols / slot and 2 μ timeslots / subframe. The subcarrier spacing can be equal to 2 μ *15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example of a parameter set μ=2 with a normal CP of 14 symbols per slot and 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is about 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP may have a specific parameter set and CP (normal or extended).

[0063] A resource grid may be used to represent the frame structure. Each slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a number of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0064] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (indicated as R for a 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).

[0065] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. A physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within a BWP may be referred to as a control resource set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during a PDCCH monitoring opportunity on a CORESET, wherein the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. A secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as an SS block (SSB)). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information such as system information blocks (SIBs) that are not sent via the PBCH, and paging messages.

[0066] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may send a DM-RS for a physical uplink control channel (PUCCH) and a DM-RS for a physical uplink shared channel (PUSCH). The PUSCH DM-RS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DM-RS may be sent in different configurations. The UE may send a sounding reference signal (SRS). The SRS may be sent in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0067] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0068] Figure 3 375. The Controller / Processor 375 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, Internet Protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes 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 transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0069] The transmit (Tx) processor 316 and receive (Rx) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) coding / 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 handles the mapping to the signal constellation diagram based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols can then be divided into parallel streams. Each stream can then 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 together using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived from reference signals and / or channel state feedback sent by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier for transmission using a corresponding spatial stream.

[0070] 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 combined into a single OFDM symbol stream by the Rx processor 356. The Rx processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal may include a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier and the reference signal are recovered and demodulated by determining the most likely signal constellation point sent by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0071] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0072] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

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

[0074] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to an Rx processor 370.

[0075] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0076] At least one of the Tx processor 368, the Rx processor 356, and the controller / processor 359 may be configured to perform Figure 1 The PRS and MG measurement components 198 combine various aspects.

[0077] Figure 4 4 is a diagram illustrating an example of UE positioning based on reference signal measurement. UE 404 may be at time T SRS_TX UL-SRS 412 is sent and at time T PRS_RX A DL positioning reference signal (PRS) (DL-PRS) 410 is received. TRP 406 may be at time T SRS_RX Receive UL-SRS 412 and at time T PRS_TX 410. UE 404 may receive DL-PRS 410 before transmitting UL-SRS 412, or may transmit UL-SRS 412 before receiving DL-PRS 410. In both cases, a positioning server (e.g., location server 168) or UE 404 may determine the UL-SRS 412 based on ||T SRS_RX -T PRS_TX |-|T SRS_TX -T PRS_RX || to determine RTT 414. Thus, multi-RTT positioning may utilize UE ERx-Tx time difference measurements (i.e., |T SRS_TX -T PRS_RX |) and DL-PRS reference signal received power (RSRP) (DL-PRS-RSRP), and the measured TRP Rx-Tx time difference measurement (ie, |T SRS_RX -T PRS_TX |) and UL-SRS-RSRP. The UE 404 measures the UE Rx-Tx time difference measurement (and optionally the DL-PRS-RSRP of the received signal) using the assistance data received from the positioning server, and the TRP 402, 406 measures the gNB Rx-Tx time difference measurement (and optionally the UL-SRS-RSRP of the received signal) using the assistance data received from the positioning server. These measurements may be used at the positioning server or the UE 404 to determine the RTT, which is used to estimate the position of the UE 404. Other methods for determining the RTT are possible, such as, for example, using DL-TDOA and / or UL-TDOA measurements.

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

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

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

[0081] UL-AoA positioning may utilize the measured azimuth angle of arrival (A-AoA) and zenith angle of arrival (Z-AoA) of uplink signals sent from the UE 404 at multiple TRPs 402, 406. The TRPs 402, 406 measure the A-AoA and Z-AoA of the received signals using assistance data received from a positioning server, and the resulting measurements are used along with other configuration information to estimate the position of the UE 404.

[0082] Additional positioning methods may be used to estimate the position of the UE 404, such as, for example, UE-side UL-AoD and / or DL-AoA. Note that data / measurements from various techniques may be combined in various ways to increase accuracy, determine and / or enhance certainty, supplement / complete measurements, and / or replace / provide missing information.

[0083] Figure 5 500 is a diagram of a PRS schedule according to various aspects of the present disclosure. The PRS schedule diagram 500 may be used to schedule a UE such as Figure 1 UE 104 or Figure 4The UE may be scheduled to receive a first PRS set 501 (ie, PRS resource #1) from a first network node and may be scheduled to receive a second PRS set 503 (ie, PRS resource #2) from a second network node.

[0084] The first PRS set 501 may be configured to be received according to a PRS resource set period or a PRS resource set instance. The first PRS set 501 may have a PRS resource set period 502 of 10 slots. In other words, the first PRS set 501 may be scheduled to be received every 10 slots. The first PRS set 501 may have a PRS resource set offset 504 of 3 slots. In other words, the first PRS set 501 may be offset by 3 slots from the start of the period. The first PRS set 501 may have a PRS resource repetition value of two. In other words, the first PRS set 501 may have two PRSs, namely a first PRS and a second PRS. The first PRS set 501 may have a PRS resource time gap 510 of one. In other words, each retransmitted PRS of the first PRS set 501 may be retransmitted one slot after a previous transmission or retransmission. The first PRS set 501 may have a PRS resource offset 506 of one. In other words, the first PRS set 501 may be transmitted one time slot after the PRS resource set offset 504. The first PRS set 501 may be received by the UE in a PRS opportunity 512 in cycle 3.

[0085] The second PRS set 503 may be configured to be received according to a PRS resource set period or a PRS resource set instance. The second PRS set 503 may have a PRS resource set period 502 of 10 slots. In other words, the second PRS set 503 may be scheduled to be received every 10 slots. The second PRS set 503 may have a PRS resource set offset 504 of 3 slots. In other words, the second PRS set 503 may be offset by 3 slots from the start of the period. The second PRS set 503 may have a PRS resource repetition value of two. In other words, the second PRS set 503 may have two PRSs, namely a first PRS and a second PRS. The second PRS set 503 may have a PRS resource time gap 510 of one. In other words, each retransmitted PRS of the second PRS set 503 may be retransmitted after one slot from the previous transmission or retransmission. The second PRS set 503 may have a PRS resource offset 508 of 4. In other words, the second PRS set 503 may be sent 4 time slots after the PRS resource set offset 504. The second PRS set 503 may be received by the UE in a PRS opportunity 514 in cycle 3.

[0086] Figure 5The illustrated PRS scheduling may be based on a reference signal transmitted by the UE, such as one or more SRSs transmitted by the UE.PRS opportunities 512 may not collide with PRS opportunities 514 because each opportunity is in a different time slot of its respective cycle.

[0087] In some aspects, the UE may be configured to perform intra-frequency PRS measurements when inter-frequency NR measurements or inter-frequency LTE measurements are configured. Inter-frequency NR measurements or inter-frequency LTE measurements may be scheduled to be measured during a measurement gap period or measurement gap opportunity. Such measurements may be, for example, SSB measurements. Such intra-frequency PRS measurements may collide with inter-frequency NR or LTE measurements during the measurement gap opportunity. When a collision occurs, the UE may be configured to prioritize measuring intra-frequency PRS or measuring inter-frequency measurements during the measurement gap. Therefore, if the PRS opportunity collides with the measurement gap opportunity, the PRS may be given a higher priority, resulting in the loss of the measurement gap opportunity, or the measurement gap may be given a higher priority, resulting in no PRS measurement. The PRS opportunity may be a time period in which the UE is configured to measure the PRS, and the measurement gap opportunity may be a time period in which the UE is configured to measure a measurement gap signal such as an SSB. Such opportunities may be scheduled by the base station and modified by the UE.

[0088] Figure 6 600 is a diagram of PRS and measurement gap scheduling according to various aspects of the present disclosure. The diagram 600 of PRS scheduling may be used to schedule a UE such as Figure 1 UE 104 or Figure 4 The UE may be scheduled to receive a first PRS set 601 (ie, PRS resource #1) from a first network node and may be scheduled to receive a second PRS set 603 (ie, PRS resource #2) from a second network node, similar to Figure 5 The first PRS set 601 and the second PRS set 503 in cycle 3 may be received by the UE in a PRS opportunity 612 in cycle 3. The second PRS set 603 may be received by the UE in a PRS opportunity 614 in cycle 3.

[0089] The UE may be configured to perform inter-frequency NR measurements during a measurement gap opportunity 616 located at slots 21 to 24. However, the measurement gap opportunity 616 may collide with a PRS opportunity 612 associated with the first PRS set 601 at slot 24 (shown as a collision slot 618). The PRS opportunity 612 associated with the first PRS set 601 may not collide with the measurement gap opportunity 616 at slot 26 (shown as a non-collision slot 620). If the UE is configured to give priority to PRS, the UE may measure the first PRS set 501 at slot 24 within the measurement gap opportunity 616. For example, the UE may perform PRS RSTD measurement at slot 24 during the PRS opportunity 612. Therefore, the UE may not perform inter-frequency measurements during the measurement gap opportunity 616. If the UE is configured to give priority to measurement gaps, the UE may perform inter-frequency NR measurements during the measurement gap opportunity 616. For example, the UE may measure and / or decode the inter-frequency SSB transmitted at time slot 24 during the measurement gap opportunity 616. Thus, the UE may not perform PRS RSTD measurements during the PRS opportunity 612.

[0090] Diagram 600 illustrates an example of a PRS opportunity 612 colliding with a measurement gap opportunity 616 having a measurement gap length of 4 slots. In NR cells configured with a measurement gap length of 6 slots or more, the probability of colliding with an intra-frequency PRS opportunity may be higher.

[0091] In some aspects, the UE may be configured to utilize both PRS measurements and gap measurements to achieve optimal functionality, such as intra-frequency PRS and inter-frequency gap measurements, when PRS occasions and measurement gap occasions collide with each other. Figure 7 700 is a diagram of a modified PRS and measurement gap scheduling according to various aspects of the present disclosure. The diagram 700 of PRS scheduling may be used to schedule a UE such as Figure 1 UE 104 or Figure 4 The UE may be scheduled to receive a first PRS set 701 (ie, PRS resource #1) from a first network node and may be scheduled to receive a second PRS set 703 (ie, PRS resource #2) from a second network node, similar to Figure 6 The first PRS set 601 and the second PRS set 603 in FIG.

[0092] exist Figure 66, the PRS opportunity 612 collides with the measurement gap opportunity 616 at slot 24. Even though slot 26 of the PRS opportunity 612 does not collide with the measurement gap opportunity 616, the UE may consider that the measurement gap opportunity 616 collides with all PRS opportunities 612, even slot 26, because the PRS opportunity 612 collides with the measurement gap opportunity 61 at slot 24. To avoid such a collision, the UE of diagram 700 may be configured to use the colliding slot 618 for gap measurement and the non-colliding slot 620 for PRS measurement such as RSTD measurement. Since the colliding slot 618 and the non-colliding slot 620 have the same retransmitted PRS in the PRS set 601, the UE can perform PRS measurement as long as the UE measures one of the two retransmitted PRSs in the PRS set 601.

[0093] Specifically, in Figure 7 , the UE may perform measurement gap measurements, such as inter-frequency NR measurements, during measurement gap opportunities 716, and may perform PRS measurements, such as measuring RSTD of PRSs in the first PRS set 701, during valid PRS opportunities 712. In other words, the UE may not measure PRSs 701 in the first PRS set 718, but may measure PRSs 701 in the first PRS set 720 during valid PRS opportunities 712. As long as the PRS resource repetition value associated with the PRS set is greater than one (which means that at least one PRS is retransmitted), the UE may skip measuring one or more PRSs in the PRS set. The UE may measure the second PRS set 703 during the PRS opportunity 714. This solution may provide an efficient way to detect collisions and efficiently manage PRS resources so that both measurement gap measurements and RSTD measurements may occur in tandem.

[0094] Figure 8 FIG. 8 is another diagram 800 of PRS and measurement gap scheduling according to various aspects of the present disclosure. The diagram 800 of PRS scheduling may be used to schedule a UE such as Figure 1 UE 104 or Figure 4404 in the UE 404). The UE may be scheduled to receive the PRS set 801 from the network node. The PRS set 801 may be configured to be received according to a PRS resource set period or a PRS resource set instance. The PRS set may have a PRS resource repetition value of two. In other words, the PRS set 801 may have two PRSs, namely a first PRS and a second PRS. The PRS set 501 may have PRS opportunities at subframes 7 and 8 at system frame number (SFN) 0. In other words, one PRS in the PRS set 801 may be at SFN 0, subframe 7, and another PRS in the PRS set 801 may be at SFN 0, subframe 8. The PRS set 801 may have a PRS resource time gap of zero. In other words, each retransmitted PRS of the PRS set 801 may be retransmitted immediately after the subframe from which it was previously transmitted or retransmitted. PRS set 801 may have a collision range 804 defined as three milliseconds (ms) before PRS opportunity 802 and two ms after PRS opportunity 802. In other words, collision range 804 of PRS set 801 may span from SFN 0, subframe 4 to SFN 1, subframe 0.

[0095] The UE may be configured to perform inter-frequency LTE measurements during measurement gap opportunities 806 located at SFN 1, subframe 0 to SFN 1, subframe 5. However, the measurement gap opportunity 806 collides with a collision range 804 of a PRS set 801 (or a PRS opportunity 802) associated with a first PRS set 801 at SFN 1, subframe 0 (shown as a collision subframe 808). If the UE is configured to give priority to PRS, the UE may measure the PRS set 801 during the PRS opportunity 802. For example, the UE may perform PRS RSTD measurements during the PRS opportunities 802 at SFN 0, subframes 7 and 8. Therefore, the UE may not perform inter-frequency measurements during the measurement gap opportunity 806 because the measurement gap opportunity 806 may collide with the collision range 804 of the PRS set 801. If the UE is configured to give priority to measurement gaps, the UE may perform inter-frequency LTE measurements during the measurement gap opportunity 806. For example, the UE may measure and / or decode the inter-frequency SSB transmitted at SFN 1, subframe 0 during the measurement gap opportunity 806. Therefore, the UE may not perform PRS RTD measurements during the PRS opportunity 802.

[0096] If the UE does not measure PRS set 801 at SFN 1, subframe 8, then the PRS opportunities 802 associated with PRS set 801 may not collide with the measurement gap opportunities 806. Fig. 9 is a diagram 900 of a modified PRS and measurement gap scheduling in accordance with various aspects of the present disclosure. Fig. 9900 is a diagram of a modified PRS and measurement gap scheduling according to various aspects of the present disclosure. The diagram 900 of PRS scheduling may be used to provide a UE such as Figure 1 UE 104 or Figure 4 The UE may be scheduled to receive a PRS set 901 from a network node, similar to Figure 8 PRS set 801 in.

[0097] exist Figure 8 , the PRS opportunity 802 collides with the measurement gap opportunity 806 at the colliding subframe 808. To avoid such a collision, the UE of diagram 900 may be configured to measure the PRS set 801 during the valid PRS opportunity 902 at SFN 0, subframe 7, and not to perform measurements during SFN 0, subframe 8. Since the PRS at SFN 0, subframe 7 and the PRS at SFN 0, subframe 8 have the same retransmitted PRS in the PRS set 901, the UE may perform PRS measurement as long as it measures one of the two retransmitted PRSs in the PRS set 801.

[0098] Specifically, in Fig. 9 , the UE may perform PRS measurements during valid PRS opportunities 902, such as measuring RSTD of PRSs in PRS set 901, and may perform measurement gap measurements, such as inter-frequency LTE measurements, during measurement gap opportunities 906. In other words, the UE may not measure the PRS set at SFN 0, subframe 8, and may measure the PRS set at SFN 0, subframe 7. Therefore, the collision range 904 may not collide with the measurement gap opportunity 906. As long as the PRS resource repetition value associated with the PRS set is greater than one (which means that at least one PRS is retransmitted), the UE may skip measuring one or more PRSs in the PRS set. This solution may provide an efficient way to detect collisions and efficiently manage PRS resources so that both measurement gap measurements and RSTD measurements can occur in tandem.

[0099] Fig.10 1000 is a diagram of a measurement gap opportunity 1006 scheduled to allow a UE to measure an SSB set 1003, however the measurement gap opportunity 1006 may not allow the UE to measure a PRS set 1001 that does not overlap with the measurement gap opportunity 1006 in accordance with various aspects of the present disclosure. The measurement gap opportunity 1006 may be scheduled for a time that is not reserved for UL / DL transmissions 1005 with the UE.

[0100] The PRS set 1001 may be configured to be received according to a PRS resource set period or a PRS resource set instance. The PRS set 1001 may have a PRS resource set period of 20 time slots. In other words, the PRS set 1001 may be scheduled to be received every 20 time slots. The PRS set 1001 may have a PRS resource set offset of 0 time slots. In other words, the PRS set 1001 may be offset by 0 time slots from the start of the period. The PRS set 1001 may have a PRS resource repetition value of two. In other words, the PRS set 1001 may have two PRSs, namely a first PRS and a second PRS. The PRS set 1001 may have a PRS resource time gap of one. In other words, each retransmitted PRS of the PRS set 1001 may be retransmitted after one time slot from a previous transmission or retransmission. The PRS set 1001 may have a PRS resource offset of seven. In other words, the PRS set 1001 may be transmitted seven time slots after the PRS resource set offset. PRS set 1001 may be received by the UE in PRS opportunity 1002 in cycle 3 .

[0101] SSB set 1003 may be configured to be received according to an SSB opportunity set period or an SSB opportunity set instance. SSB set 1003 may have an SSB opportunity period of 20 slots. In other words, SSB set 1003 may be scheduled to be received every 20 slots. SSB set 1003 may have an SSB opportunity set offset of 2 slots. In other words, SSB set 1003 may be offset by 2 slots from the start of the period. SSB set 1003 may have a size of three slots. SSB set 1003 may be received by the UE in SSB opportunity 1004 in period 3.

[0102] The measurement gap opportunity 1006 may be configured to be scheduled during a time period that is not reserved for UL / DL transmission 1005 with the UE. The measurement gap opportunity 1006 may have a measurement gap period of 20 slots. In other words, the measurement gap opportunity 1006 may be scheduled every 20 slots. The measurement gap opportunity 1006 may have a measurement gap offset of one slot. In other words, the measurement gap opportunity 1006 may be offset from the start of the period by one slot. The measurement gap opportunity 1006 may have a size of five slots. A set of five slots may be the largest possible measurement gap opportunity, which prevents the measurement gap opportunity 1006 with five slots from covering both the SSB opportunity of three slots and the PRS opportunity of three slots.

[0103] The SSB opportunity 1004 may be scheduled by the UE's serving cell or a neighbor cell. The measurement gap opportunity 1006 may be configured to allow the UE to measure the SSB set 1003 during the SSB opportunity 1004, but may not be large enough to allow the UE to measure the SSB set 1003 and the PRS set 1001 during the measurement gap opportunity 1006. In some aspects, the UE may not be able to perform a positioning session because there is no gap configuration available for positioning. The positioning frequency layer (PFL) of the PRS set 1001 may be different from the UE's active BWP. The UE may be in a bad network condition where a handover event has begun, thereby preventing the UE from skipping measuring the SSB because decoding the SSB may have a critical priority for the UE. Although the UE may send a request to its serving cell to change the measurement gap opportunity 1006 to overlap with the PRS set 1001 instead of the SSB set 1003, the serving cell may reject this request because if the UE does not measure the SSB set 1003, there may be a chance of handover failure. The serving cell may not be able to allocate a measurement gap large enough to accommodate both the SSB opportunity 1004 and the PRS opportunity 1002. In some aspects, if the UE cannot accommodate both the SSB opportunity 1004 and the PRS opportunity 1002, the UE may abort the positioning session.

[0104] Fig.11 is a diagram 1100 of a measurement gap opportunity 1106 that has been opened by a UE to allow the UE to measure a portion of an SSB set 1103 and one PRS in a PRS set 1101 in accordance with various aspects of the present disclosure. The PRS set 1101 may be equivalent to Fig.10 The PRS set 1001 in , and the SSB set 1103 may be equivalent to Fig.10 However, the time slots reserved for UL / DL transmission 1105 may not allow UL / DL transmission during time slots 26 and 27 of cycle 3 to allow measurement gap opportunity 1106 to overlap with the first PRS in PRS set 1101 at time slot 27. Instead, the reserved time slot set for UL / DL transmission 1105 may allow UL / DL transmission during time slots 21 and 22 of cycle 3.

[0105] The measurement gap opportunity 1106 may be kept 5 slots large, allowing the UE to measure the first PRS of PRS set 1101 at slot 27 during valid PRS opportunity 1104, and to measure a portion of SSB set 1103, specifically SSB set 1103, at slots 23 and 24 during SSB opportunity 1102. However, the collision slot 1108 collides with the reserved slot for UL / DL transmission 1105, which prevents the measurement gap opportunity 1106 from allowing SSB set 1103 to be measured in its entirety by the UE. The UE may be configured to open the measurement gap opportunity 1106 in situations where both SSB measurements and positioning measurements are critical to the UE, such as when both have a priority above a threshold (e.g., handover and 911 initiated positioning measurements occur simultaneously). The UE may optimize its procedures to allow decoding of at least one PRS signal as well as SSBs that the UE may be able to measure / decode. The UE may be configured to minimize the loss of SSB signals and thus open its own measurement gaps appropriately when the data scheduling is not heavy (ie, less than or equal to a threshold).

[0106] Fig.12 FIG. 1200 is a diagram of a measurement gap opportunity 1206 that has been opened by a UE to allow the UE to measure an SSB set 1203 and a PRS set 1201 in accordance with various aspects of the present disclosure. The PRS set 1201 may be equivalent to Fig.10 The PRS set 1001 in and the SSB set 1203 may be equivalent to Fig.10 However, the set of slots reserved for UL / DL transmission 1205 may not allow UL / DL transmission during slots 26, 27, and 28 of cycle 3 to allow measurement gap opportunities 1206 to overlap with the PRS set 1201 at slots 27 and 28.

[0107] The measurement gap opportunity 1206 may be greater than Fig.10 1202 during the valid PRS opportunity 1202, thereby allowing the UE to measure the first PRS in the PRS set 1201 at time slot 27 during the valid PRS opportunity 1202, and measure the entire SSB set 1203 during the SSB opportunity 1204. The UE may be configured to open the measurement gap opportunity 1206 in the case where the SSB measurement and positioning measurement are critical to the UE, such as when both have a priority above a threshold (e.g., handover and 911 initiated positioning measurements occur at the same time). The UE may optimize its process to allow decoding of at least one PRS signal and the SSB that the UE may be able to measure / decode. The UE may be configured to minimize the loss of the SSB signal by measuring the entire SSB set 1203 while still allowing the UE to measure at least one PRS in the PRS set 1201, thereby opening its own measurement gap in a timely manner when the data scheduling is not heavy (i.e., less than or equal to the threshold).

[0108] Fig.13 is a diagram 1300 of a PPW opportunity 1306 that has been requested by a UE to allow the UE to measure an SSB set 1303 and a PRS set 1301 in accordance with various aspects of the present disclosure. The PRS set 1301 may be equivalent to Fig.10 The PRS set 1001 and SSB set 1303 in Fig.10 The SSB set 1003 in , and the UL / DL transmission set 1305 may be equivalent to Fig.10 The UE may ignore the measurement gaps scheduled by the network in order to measure the signal during the PPW opportunities 1306. However, due to the granted PPW, the network may not schedule any UL / DL transmissions during time slots 26 to 30.

[0109] PPW opportunity 1306 may be greater than Fig.10 1304, thereby allowing the UE to measure the PRS set 1301 during the PRS opportunity 1302 and the entire SSB set 1303 during the SSB opportunity 1304. The UE may be configured to request the PPW opportunity 1306 in the case where SSB measurements and positioning measurements are critical to the UE, such as when both have a priority above a threshold (e.g., handover and 911 initiated positioning measurements occur simultaneously). The UE may request a PPW for the PFL that is different from the PRS set 1301 and may measure the PRS set 1301 using only the time period allocated to the PPW. In other words, the UE may consider the PPW opportunity 1306 to be the same as the measurement gap opportunity and may tune to any suitable frequency, such as the PFL corresponding to the PRS set 1301. The UE may be preconfigured to prioritize the PRS over the PPW, thereby allowing the UE to ignore the PFL associated with the PPW. In some aspects, the UE may be configured to request a PPW of a size required to decode the PRS set 1301 (e.g., slots 26 to 29), thereby extending the effective length of the measurement gap without requesting all slots 21 to 30. In some aspects, the UE may be configured to both open its own measurement gaps and request a PPW, which may reduce PRS resource processing to have less impact on serving cell channel performance loss.

[0110] Fig.14 1400 is a flow chart of a method of wireless communication. The method may be performed by a UE (e.g., UE 104, UE 350, UE device 1604). At 1402, the UE may obtain a first indication of a first measurement gap resource associated with a first time period. 1402 may be performed by Fig.16 The component 198 in is executed. The measurement gap resource can be a scheduled frequency band that the UE can use to measure a signal (such as an SSB) during the measurement gap.

[0111] At 1404, the UE may receive a PRS set during a PRS opportunity, wherein a first portion of the PRS opportunity may not overlap with any portion of the first time period. Fig.16 Component 198 in is executed.

[0112] At 1406, the UE may measure the PRS set at the first portion of the PRS opportunity based on at least one of (i) a first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with the second time period overlapping with the first portion of the PRS opportunity, or (iii) a PPW associated with a third time period overlapping with the first portion of the PRS opportunity. 1406 may be performed by Fig.16 198 in the component 198. The PPW can be a window requested by the UE from the network node serving the UE, during which the UE can measure signals, such as SSB, PDSCH, or PDCCH. The PPW can allocate resources and time periods to the UE during which the network node does not schedule any UL or DL ​​transmissions with the UE, similar to measurement gap opportunities. During the PPW, the UE can choose whether to focus on any resources other than those associated with the PPW, thereby allowing the UE to measure PRS even though the PRS may be transmitted using resources other than those associated with the PPW.

[0113] Fig.15 1500 is another flow chart of a method of wireless communication. The method may be performed by a UE (e.g., UE 104, UE 350, UE device 1604). At 1502, the UE may obtain a first indication of a first measurement gap resource associated with a first time period. 1502 may be performed by Fig.16 Component 198 in is executed.

[0114] At 1504, the UE may receive a PRS set during a PRS opportunity, wherein a first portion of the PRS opportunity may not overlap with any portion of the first time period. Fig.16 Component 198 in is executed.

[0115] At 1506, the UE may measure the PRS set at the first portion of the PRS opportunity based on at least one of (i) a first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with the second time period overlapping with the first portion of the PRS opportunity, or (iii) a PPW associated with a third time period overlapping with the first portion of the PRS opportunity. 1506 may be performed by Fig.16 Component 198 in is executed.

[0116] At 1508, the UE may allocate a second measurement gap resource associated with a second time period overlapping with the first portion of the PRS opportunity and / or send a request for a PPW associated with a third time period overlapping with the first portion of the PRS opportunity. Fig.16 Component 198 in is executed.

[0117] At 1510, the UE may receive an RRC configuration including a set of preconfigured measurement gap time periods, wherein the second time period may be selected based on the RRC configuration. Fig.16 Component 198 in is executed.

[0118] At 1512, the UE may select a second time period from a set of preconfigured measurement gap time periods. Fig.16 Component 198 in is executed.

[0119] At 1514, the UE may select a second time period to overlap with a first portion of PRS opportunities and not overlap with a second portion of PRS opportunities, wherein the first portion of PRS opportunities may include a first PRS in a PRS set and the second portion of PRS opportunities may include a second PRS in the PRS set, wherein the first PRS and the second PRS may be associated with the same PRS measurement. Fig.16 Component 198 in is executed.

[0120] At 1516, the UE may receive a configuration for the PPW that prioritizes measurement of the PRS over inter-frequency transmissions, wherein a request for the PPW associated with the third time period may be sent for a first PFL, wherein the PRS set may be further measured at a second PFL different from the first PFL. 1516 may be performed by Fig.16 Component 198 in is executed.

[0121] Fig.161600 is a diagram illustrating an example of a hardware implementation for an apparatus 1604. The apparatus 1604 may be a UE, a component of a UE, or may implement UE functionality. In some aspects, the apparatus 1604 may include a cellular baseband processor 1624 (also referred to as a modem) coupled to one or more transceivers 1622 (e.g., a cellular RF transceiver).

In some aspects, the apparatus 1604 may also include one or more subscriber identity module (SIM) cards 1620 and an application processor 1606 coupled to a secure digital (SD) card 1608 and a screen 1610.

The additional memory module 1626 may also be considered a computer-readable medium / memory. Each computer-readable medium / memory 1624', 1606', 1626 may be non-transitory. The cellular baseband processor 1624 and the application processor 1606 are each responsible for general processing, including executing software stored on the computer-readable medium / memory. The software, when executed by the cellular baseband processor 1624 / application processor 1606, enables the cellular baseband processor 1624 / application processor 1606 to perform the various functions described above. The computer-readable medium / memory may also be used to store data manipulated by the cellular baseband processor 1624 / application processor 1606 when executing the software. The cellular baseband processor 1624 / application processor 1606 may be a component of the UE 350 and may include the memory 360 and / or at least one of the Tx processor 368 , the Rx processor 356 , and the controller / processor 359 .In one configuration, the device 1604 may be a processor chip (modem and / or applications) and include only the cellular baseband processor 1624 and / or the application processor 1606, and in another configuration, the device 1604 may be an entire UE (eg, see. Figure 3 350) and includes additional modules of device 1604.

[0122] As discussed above, component 198 is configured to obtain a first indication of a first measurement gap resource associated with a first time period. Component 198 may be configured to receive a PRS set during a PRS opportunity. The first portion of the PRS opportunity may not overlap with any portion of the first time period.

Component 198 may be one or more hardware components specifically configured to perform the process / algorithm, implemented by one or more processors configured to perform the process / algorithm, stored in a computer-readable medium for implementation by one or more processors, or some combination thereof. As shown, the device 1604 may include a variety of components configured for various functions. In one configuration, the apparatus 1604 (and in particular the cellular baseband processor 1624 and / or the application processor 1606) may include means for obtaining a first indication of a first measurement gap resource associated with a first time period. The apparatus 1604 may include means for receiving a PRS set during a PRS opportunity.
