Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 078,164, entitled “DYNAMIC CONFIGURATION OF MEASUREMENT GAPS”, filed September 14, 2020, and U.S. Non-Provisional Patent Application No. 17 / 471,016, entitled “DYNAMIC CONFIGURATION OF MEASUREMENT GAPS”, filed September 9, 2021, both of which are assigned to the assignee of this application and are expressly incorporated herein by reference in their entirety. Technical Field

[0003] The various aspects of this disclosure generally relate to wireless communications. Background Technology

[0004] Wireless communication systems have undergone multiple generations of development, including first-generation analog radiotelephone service (1G), second-generation (2G) digital radiotelephone service (including temporary 2.5G and 2.75G networks), third-generation (3G) high-speed data, wireless services supporting the Internet, and fourth-generation (4G) services (e.g., Long Term Evolution (LTE) or WiMax). Currently, many different types of wireless communication systems are used, including cellular and Personal Communication Services (PCS) systems. Known examples of cellular systems include cellular analog Advanced Mobile Phone Systems (AMPS), and digital cellular systems based on Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), etc.

[0005] The fifth-generation (5G) wireless standard (known as New Radio (NR)) demands higher data transmission speeds, a greater number of connections, and better coverage, among other improvements. According to the Next Generation Mobile Networks Alliance (NGC), the 5G standard is designed to provide tens of megabits per second of data to each of tens of thousands of users, and 1 gigabit per second to dozens of workers on an office floor. To support large-scale sensor deployments, it should support hundreds of thousands of simultaneous connections. Therefore, the spectral efficiency of 5G mobile communications should be significantly improved compared to the current 4G standard. Furthermore, signaling efficiency should be improved and latency should be significantly reduced compared to the current standard. Summary of the Invention

[0038] In the following description and accompanying drawings, various aspects of this disclosure are provided for illustrative purposes with reference to various examples. Alternative aspects may be devised without departing from the scope of this disclosure. Furthermore, elements well-known in this disclosure will not be described in detail or will be omitted so as not to obscure the relevant details of this disclosure.

[0039] As used herein, the terms “exemplary” and / or “example” mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” and / or “example” is not necessarily to be construed as preferred or advantageous over other aspects. Similarly, the term “aspects of this disclosure” does not require that all aspects of this disclosure include the features, advantages, or patterns of the operation discussed.

[0040] Those skilled in the art will understand that the information and signals described below can be represented using any of a variety of different techniques and methods. For example, depending in part on the specific application, in part on the desired design, in part on the corresponding technology, the data, instructions, commands, information, signals, bits, symbols, and chips referenced throughout the following description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or optical particles, or any combination thereof.

[0041] Furthermore, multiple aspects can be described based on sequences of actions to be performed, for example, by elements of a computing device. It will be appreciated that the various actions described herein can be performed by specific circuitry (e.g., an application-specific integrated circuit (ASIC)), program instructions executed by one or more processors, or a combination of both. Furthermore, the sequences of actions described herein can be considered fully implemented on any form of non-transitory computer-readable storage medium on which a corresponding set of computer instructions is stored, which, when executed, will cause or instruct the associated processor of the device to perform the functions described herein. Therefore, various aspects of this disclosure can be implemented in several different forms, all of which are contemplated within the scope of the claimed subject matter. Moreover, for each aspect described herein, the corresponding form of any such aspect may be described herein as, for example, “logic configured” to perform the described actions.

[0042] As used herein, unless otherwise indicated, the terms “User Equipment” (UE) and “Base Station” (BS) are not intended to be specific or otherwise limited to any particular Radio Access Technology (RAT). Generally, a UE can be any wireless communication device used by a user to communicate over a wireless communication network (e.g., mobile phone, router, tablet computer, laptop computer, tracking device, wearable device (e.g., smartwatch, glasses, augmented reality (AR) / virtual reality (VR) headset, etc.), vehicle (e.g., car, motorcycle, bicycle, etc.), Internet of Things (IoT) device, etc.). A UE can be mobile or may (e.g., at certain times) be stationary and can communicate with a Radio Access Network (RAN). As used herein, the term “UE” can be interchangeably referred to as “Access Terminal” or “AT,” “Client Equipment,” “Wireless Equipment,” “Subscriber Equipment,” “Subscriber Terminal,” “Subscriber Station,” “User Terminal” or “UT,” “Mobile Equipment,” “Mobile Terminal,” “Mobile Station,” or variations thereof. Typically, a UE can communicate with a core network via the RAN, and through the core network, a UE can connect to external networks such as the Internet and to other UEs. Of course, other mechanisms for connecting to the core network and / or the Internet are also possible for the UE, such as through a wired access network, a wireless local area network (WLAN) network (e.g., based on IEEE 802.11, etc.).

[0043] Depending on the network in which it is deployed, a base station can communicate with a UE based on one of several RATs and may be alternatively referred to as an Access Point (AP), network entity, NodeB, evolved NodeB (eNB), next-generation eNB (ng-eNB), new radio (NR) Node B (also known as gNB or gNodeB), etc. A base station can primarily be used to support the UE's radio access, including supporting data, voice, and / or signaling connections for the supported UE. In some systems, the base station may only provide edge node signaling functions, while in others, it may provide additional control and / or network management functions. The communication link through which the UE signals to the base station is referred to as an uplink (UL) channel (e.g., reverse traffic channel, reverse control channel, access channel, etc.). The communication link through which the base station signals to the UE is referred to as a downlink (DL) or forward link channel (e.g., paging channel, control channel, broadcast channel, forward traffic channel, etc.). As used herein, the term traffic channel (TCH) can refer to either an uplink / reverse or downlink / forward traffic channel.

[0044] The term "base station" can refer to a single physical transmit-receive point (TRP) or multiple physical TRPs that may be co-located or non-co-located. For example, when the term "base station" refers to a single physical TRP, the physical TRP can be the antenna of a base station corresponding to a cell (or several cell sectors) of the base station. When the term "base station" refers to multiple co-located physical TRPs, the physical TRP can be an array of antennas of the base station (e.g., in a multiple-input multiple-output (MIMO) system or where the base station uses beamforming). When the term "base station" refers to multiple non-co-located physical TRPs, the physical TRP can be a distributed antenna system (DAS) (a network of spatially separated antennas connected to a common source via a transmission medium) or a remote radio headend (RRH) (a remote base station connected to the serving base station). Alternatively, non-co-located physical TRPs can be the serving base station receiving measurement reports from the UE and a neighboring base station where the UE is measuring its reference RF signal (or simply "reference signal"). Since a TRP is the point through which a base station transmits and receives wireless signals, as used herein, references to transmissions from or receptions at a base station will be understood to refer to the specific TRP of the base station.

[0045] In some implementations that support UE positioning, the base station may not support the UE's radio access (e.g., it may not support the UE's data, voice, and / or signaling connections), but it may instead send reference signals to the UE for measurement, and / or receive and measure the signals sent by the UE. Such a base station may be referred to as a positioning beacon (e.g., when sending signals to the UE) and / or a location measurement unit (e.g., when receiving and measuring signals from the UE).

[0046] An “RF signal” refers to an electromagnetic wave of a given frequency that transmits information across space between a transmitter and a receiver. As used herein, a transmitter may send a single “RF signal” or multiple “RF signals” to a receiver. However, due to the propagation characteristics of RF signals through multipath channels, a receiver may receive multiple “RF signals” corresponding to each transmitted RF signal. The same transmitted RF signal on different paths between the transmitter and receiver can be referred to as a “multipath” RF signal. As used herein, an RF signal may also be referred to as a “wireless signal” or simply a “signal,” where the term “signal” clearly refers to either a wireless signal or an RF signal, as will be apparent from the context.

[0047] Figure 1An exemplary wireless communication system 100 is illustrated according to various aspects. The wireless communication system 100 (also referred to as a wireless wide area network (WWAN)) may include various base stations 102 and various UEs 104. Base station 102 may include macro cell base stations (high-power cellular base stations) and / or small cell base stations (low-power cellular base stations). In one aspect, macro cell base stations may include eNBs and / or ng-eNBs (wherein wireless communication system 100 corresponds to an LTE network), or gNBs (wherein wireless communication system 100 corresponds to an NR network), or a combination of both, and small cell base stations may include femtocells, picocells, microcells, etc.

[0048] Base station 102 can collectively form a RAN and connect to core network 170 (e.g., Evolved Packet Core (EPC) or 5G Core (5GC)) via backhaul link 122, and connect to one or more location servers 172 (e.g., which may be part of core network 170 or external to core network 170) via core network 170. Among other functions, base station 102 can perform functions associated with one or more of the following: transmitting 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 for Non-Access Stratum (NAS) messages, NAS node selection, synchronization, RAN sharing, Multimedia Broadcast Multicast Service (MBMS), subscriber and device tracking, RAN Information Management (RIM), paging, location, and warning message delivery. Base station 102 can communicate with each other directly or indirectly (e.g., via EPC / 5GC) on backhaul link 134, which can be wired or wireless.

[0049] Base station 102 can wirelessly communicate with UE 104. Each of base stations 102 can provide communication coverage for a corresponding geographical coverage area 110. In one aspect, within each coverage area 110, one or more cells can be supported by base station 102. A “cell” is a logical communication entity used to communicate with a base station (e.g., via some frequency resources called carrier frequency, component carrier, carrier, frequency band, etc.) and can be associated with an identifier (e.g., Physical Cell Identifier (PCI), Virtual Cell Identifier (VCI), Cell Global Identifier (CGI)) used to distinguish cells operating on the same or different carrier frequencies. In some cases, different cells can be configured according to different protocol types that provide access to different types of UEs (e.g., Machine Type Communication (MTC), Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB), or others). Since a cell is supported by a specific base station, depending on the context, the term “cell” can refer to either or both of the logical communication entity that supports it and the base station. Furthermore, since the TRP is typically the physical transmission point of a cell, the terms “cell” and “TRP” are used interchangeably. In some cases, the term "cell" can also refer to the geographic coverage area (e.g., sector) of a base station, where a carrier frequency can be detected and used for communication within certain portions of the geographic coverage area 110.

[0050] While the geographic coverage areas 110 of adjacent macro cell base stations 102 may partially overlap (e.g., in handover areas), some of the geographic coverage areas 110 may substantially overlap with larger geographic coverage areas 110. For example, a small cell base station 102' may have a coverage area 110' that substantially overlaps with the coverage areas 110 of one or more macro cell base stations 102. A network that includes both small and macro cell base stations may be referred to as a heterogeneous network. A heterogeneous network may also include home eNBs (HeNBs) that can provide service to restricted groups referred to as Closed Subscriber Groups (CSGs).

[0051] The communication link 120 between base station 102 and UE 104 may include uplink (also known as reverse link) transmission from UE 104 to base station 102 and / or downlink (also known as forward link) transmission from base station 102 to UE 104. The communication link 120 may use MIMO antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link 120 may use one or more carrier frequencies. Carrier allocation may be asymmetric for downlink and uplink (e.g., more or fewer carriers may be allocated to the downlink compared to the uplink).

[0052] The wireless communication system 100 may also include a wireless local area network (WLAN) access point (AP) 150, which communicates with a WLAN station (STA) 152 via a communication link 154 in unlicensed spectrum (e.g., 5 GHz). When communicating in unlicensed spectrum, the WLAN STA 152 and / or WLAN AP 150 may perform a free channel assessment (CCA) or a listen-before-talk (LBT) before communication to determine whether the channel is available.

[0053] Small cell base station 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell base station 102' can employ LTE or NR technology and use the same 5GHz unlicensed spectrum as WLAN AP 150. Using LTE / 5G in unlicensed spectrum can improve coverage of the access network and / or increase its capacity. NR in unlicensed spectrum can be referred to as NR-U. LTE in unlicensed spectrum can be referred to as LTE-U, Licensed Assisted Access (LAA), or MulteFire.

[0054] The wireless communication system 100 may also include a millimeter-wave (mmW) base station 180, which can communicate with the UE 182 at mmW and / or near-mmW frequencies. Extremely high frequency (EHF) is a portion of the electromagnetic spectrum that contains radio frequency (RF). EHF ranges from 30 GHz to 300 GHz and has wavelengths between 1 mm and 10 mm. Radio waves in this band can be referred to as millimeter waves. Near-mmW can extend down to 3 GHz frequencies with wavelengths of 100 mm. Ultra-high frequency (SHF) bands extend between 3 GHz and 30 GHz, and are also referred to as centimeter waves. Communication using mmW / near-mmW radio bands has high path loss and relatively short range. The mmW base station 180 and the UE 182 can utilize beamforming (transmit and / or receive) on the mmW communication link 184 to compensate for the extremely high path loss and short range. Furthermore, it will be appreciated that in alternative configurations, one or more base stations 102 may also use mmW or near-mmW and beamforming for transmission. Therefore, it will be recognized that the foregoing description is merely illustrative and should not be construed as limiting the various aspects disclosed herein.

[0055] Transmit beamforming is a technique used to focus RF signals in a specific direction. Traditionally, when a network entity (e.g., a base station) broadcasts an RF signal, it broadcasts the signal in all directions (omnidirectionally). Using transmit beamforming, the network entity determines where a given target device (e.g., a UE) is located (relative to the transmitting network entity) and projects a stronger downlink RF signal in that specific direction, thus providing a faster (in terms of data rate) and stronger RF signal to (multiple) receiving devices. To change the directionality of the RF signal transmission, the network entity can control the phase and relative amplitude of the RF signal at each of one or more transmitters broadcasting the RF signal. For example, the network entity can use an array of antennas (called a "phased array" or "antenna array") that generates beams that can be "guided" to point RF waves in different directions without actually moving the antennas. Specifically, RF currents from the transmitters are fed to the individual antennas with a precise phase relationship so that radio waves from different antennas are superimposed to increase radiation in the desired direction while canceling out radiation in undesired directions.

[0056] Transmit beams can be quasi-co-located, meaning they appear to have the same parameters to the receiver (e.g., UE), regardless of whether the transmit antennas of the network entities are physically co-located. In NR, there are four types of quasi-co-location (QCL) relationships. Specifically, a given type of QCL relationship means that certain parameters of the second reference RF signal on the second beam can be derived from information about the source reference RF signal on the source beam. Therefore, if the source reference RF signal is QCL type A, the receiver can use the source reference RF signal to estimate the Doppler offset, Doppler spread, average delay, and delay spread of the second reference RF signal transmitted on the same channel. If the source reference RF signal is QCL type B, the receiver can use the source reference RF signal to estimate the Doppler offset and Doppler spread of the second reference RF signal transmitted on the same channel. If the source reference RF signal is QCL type C, the receiver can use the source reference RF signal to estimate the Doppler offset and average delay of the second reference RF signal transmitted on the same channel. If the source reference RF signal is of type QCL D, the receiver can use the source reference RF signal to estimate the spatial reception parameters of a second reference RF signal transmitted on the same channel.

[0057] In receive beamforming, a receiver uses a receive beam to amplify an RF signal detected on a given channel. For example, the receiver may increase the gain setting of an antenna array in a particular direction and / or adjust the phase setting of the antenna array in a particular direction to amplify (e.g., increase the gain level) the RF signal received from that direction. Therefore, when a receiver is considered to be beamforming in a certain direction, it means that the beam gain in that direction is high relative to the beam gain along other directions, or that the beam gain in that direction is the highest compared to the beam gain of all other receive beams available to the receiver in that direction. This results in a stronger received signal strength (e.g., reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR), etc.) of the RF signal received from that direction.

[0058] The receive beam can be spatially correlated. Spatial correlation means that the parameters of the transmit beam for the second reference signal can be derived from information about the receive beam of the first reference signal. For example, the UE can use a specific receive beam to receive one or more reference downlink reference signals (e.g., Position Reference Signal (PRS), Tracking Reference Signal (TRS), Phase Tracking Reference Signal (PTRS), Cell Specific Reference Signal (CRS), Channel State Information Reference Signal (CSI-RS), Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Synchronization Signal Block (SSB), etc.) from the base station. Then, the UE can form a transmit beam based on the parameters of the receive beam for transmitting one or more uplink reference signals (e.g., Uplink Position Reference Signal (UL-PRS), Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), PTRS, etc.) to the base station.

[0059] Note that, depending on the entity forming the beam, a "downlink" beam can be either a transmit beam or a receive beam. For example, if a base station is forming a downlink beam to transmit a reference signal to a UE, then the downlink beam is a transmit beam. However, if the UE is forming a downlink beam, then it is a receive beam used to receive downlink reference signals. Similarly, depending on the entity forming the beam, an "uplink" beam can be either a transmit beam or a receive beam. For example, if a base station is forming an uplink beam, then it is an uplink receive beam, and if the UE is forming an uplink beam, then it is an uplink transmit beam.

[0060] In 5G, the spectrum in which radio nodes (e.g., base stations 102 / 180, UE 104 / 182) operate is divided into multiple frequency ranges: FR1 (from 450 to 6000 MHz), FR2 (from 24250 to 52600 MHz), FR3 (above 52600 MHz), and FR4 (between FR1 and FR2). In multi-carrier systems (such as 5G), one of the carrier frequencies is called the “primary carrier” or “anchor carrier” or “primary serving cell” or “PCell,” and the remaining carrier frequencies are called “secondary carriers” or “secondary serving cells” or “SCell.” In carrier aggregation, the anchor carrier is the carrier operating on the primary frequency (e.g., FR1) used by UE 104 / 182 and the cell in which UE 104 / 182 either performs an initial Radio Resource Control (RRC) connection establishment procedure or initiates an RRC connection re-establishment procedure. The primary carrier carries all common and UE-specific control channels and can be a carrier in a licensed frequency (however, not always). A secondary carrier is a carrier operating on a second frequency (e.g., FR2). This carrier can be configured once an RRC connection is established between UE 104 and the anchor carrier, and it can be used to provide additional radio resources. In some cases, the secondary carrier may be a carrier on an unlicensed frequency. The secondary carrier may contain only the necessary signaling information and signals; for example, UE-specific signaling information and signals may not be present on the secondary carrier, as both the primary uplink and downlink carriers are typically UE-specific. This means that different UEs 104 / 182 within a cell can have different downlink primary carriers. The same applies to the uplink primary carrier. The network can change the primary carrier of any UE 104 / 182 at any time. For example, this is done to balance the load on different carriers. Since a “serving cell” (which is a PCell or SCell) corresponds to the carrier frequency / component carrier on which some base stations are communicating, the terms “cell,” “serving cell,” “component carrier,” “carrier frequency,” etc., are used interchangeably.

[0061] For example, still refer to Figure 1 One of the frequencies used by the macro cell base station 102 can be an anchor carrier (or "PCell"), and the other frequencies used by the macro cell base station 102 and / or the mmW base station 180 can be secondary carriers ("SCell"). Simultaneous transmission and / or reception on multiple carriers enables the UE 104 / 182 to significantly increase its data transmission and / or reception rates. For example, compared to the data rate obtained by a single 20MHz carrier, the aggregation of two 20MHz carriers in a multi-carrier system will theoretically typically result in a doubling of the data rate (i.e., 40MHz).

[0062] The wireless communication system 100 may also include one or more UEs (such as UE 190) that are indirectly connected to one or more communication networks via one or more device-to-device (D2D) peer-to-peer (P2P) links (referred to as "side links"). Figure 1 In the example, UE 190 has a D2D P2P link 192 with one of UEs 104 connected to one of base stations 102 (e.g., through which UE 190 can indirectly obtain cellular connectivity) and a D2DP2P link 194 with a WLAN STA 152 connected to a WLAN AP 150 (through which UE 190 can indirectly obtain WLAN-based internet connectivity). In the example, D2D P2P links 192 and 194 can be connected via, for example, LTE Direct (LTE-D), WiFi Direct (WiFi-D), etc. Any well-known D2D RAT support, etc.

[0063] The wireless communication system 100 may also include a UE 164, which can communicate with the macro cell base station 102 on the communication link 120 and / or with the mmW base station 180 on the mmW communication link 184. For example, the macro cell base station 102 may support PCells and one or more SCells for the UE 164, and the mmW base station 180 may support one or more SCells for the UE 164.

[0064] Figure 2A An example wireless network architecture 200 is illustrated. For example, the 5GC 210 (also known as the Next Generation Core (NGC)) can be functionally considered as control plane (C plane) functions 214 (e.g., UE registration, authentication, network access, gateway selection, etc.) and user plane (U plane) functions 212 (e.g., UE gateway functions, access data network, IP routing, etc.), which operate collaboratively to form the core network. The user plane interface (NG-U) 213 and the control plane interface (NG-C) 215 connect the gNB 222 to the 5GC 210, and specifically to the user plane functions 212 and control plane functions 214, respectively. In an additional configuration, the ng-eNB 224 can also connect to the 5GC 210 via the NG-C 215 to the control plane function 214 and the NG-U 213 to the user plane function 212. Furthermore, the ng-eNB 224 can communicate directly with the gNB 222 via a backhaul connection 223. In some configurations, the next-generation RAN (NG-RAN) 220 may have one or more gNBs 222, while other configurations include one or more of ng-eNBs 224 and gNBs 222. The gNB 222 or ng-eNB 224 (or both) may communicate with one or more UEs 204 (e.g., any UE described herein).

[0065] Another optional aspect may include location server 230, which can communicate with 5GC 210 to provide location assistance for (multiple) UEs 204. Location server 230 may be implemented as multiple separate servers (e.g., physically separate servers, different software modules on a single server, different software modules distributed across multiple physical servers, etc.), or alternatively, each may correspond to a single server. Location server 230 may be configured to support one or more location services for UE 204, which may connect to location server 230 via the core network, 5GC 210, and / or via the Internet (not shown). Furthermore, location server 230 may be integrated into a component of the core network, or alternatively, may be located outside the core network (e.g., a third-party server, such as an original equipment manufacturer (OEM) server or a service server).

[0066] Figure 2B The diagram illustrates another example wireless network architecture 250.5GC 260 (which can correspond to...). Figure 2AThe 5GC 260 can be functionally viewed as a control plane function provided by the Access and Mobility Management Function (AMF) 264 and a user plane function provided by the User Plane Function (UPF) 262, which work together to form the core network (i.e., 5GC 260). The AMF 264's functions include registration management, connection management, reachability management, mobility management, lawful interception, transmission of session management (SM) messages between one or more UEs 204 (e.g., any UE described herein) and the Session Management Function (SMF) 266, a transparent proxy service for routing SM messages, access authentication and access authorization, transmission of short message service (SMS) messages between the UE 204 and the Short Message Service Function (SMSF) (not shown), and a Security Anchor Function (SEAF). The AMF 264 also interacts with the Authentication Server Function (AUSF) (not shown) and the UE 204, and receives an intermediate key created as a result of the UE 204's authentication process. In the case of UMTS (Universal Mobile Telecommunications System) Subscriber Identity Module (USIM) authentication, the AMF 264 retrieves security material from the AUSF. The AMF 264 also includes Security Context Management (SCM). The SCM receives a key from the SEAF used to derive a network-specific key for access. The AMF 264 also includes location service management for regulatory services, transmission of location service messages between the UE 204 and the Location Management Function (LMF) 270 (which acts as a location server 230), transmission of location service messages between the NG-RAN 220 and the LMF 270, allocation of EPS-carried identifiers for interaction with the Evolved Packet System (EPS), and UE 204 mobility event notification. Furthermore, the AMF 264 supports functions for accessing non-3GPP (3rd Generation Partnership Project) networks.

[0067] The functions of UPF 262 include acting as an anchor point for intra / inter-RAT mobility (where applicable), acting as an external Protocol Data Unit (PDU) session point interconnecting to a data network (not shown), providing packet routing and forwarding, packet inspection, user plane policy rule enforcement (e.g., gating, redirection, traffic orientation), lawful eavesdropping (user plane collection), traffic usage reporting, quality of service (QoS) processing for the user plane (e.g., uplink / downlink rate enforcement, reflected QoS marking in the downlink), uplink traffic verification (mapping of Service Data Flow (SDF) to QoS Flow), transport-level packet marking in the uplink and downlink, downlink packet buffering and downlink data notification triggering, and issuing and forwarding one or more "end markers" to the source RAN node. UPF 262 can also support the transmission of location service messages on the user plane between UE 204 and a location server (such as SLP272).

[0068] The functions of SMF 266 include session management, UE Internet Protocol (IP) address allocation and management, selection and control of user plane functions, configuration of service orientation on UPF 262 for routing services to appropriate destinations, control of policy enforcement and QoS portions, and downlink data notification. The interface through which SMF 266 communicates with AMF 264 is called the N11 interface.

[0069] Another optional aspect may include an LMF 270, which can communicate with the 5GC 260 to provide location assistance to the UE 204. The LMF 270 can be implemented as multiple separate servers (e.g., physically separate servers, different software modules on a single server, different software modules distributed across multiple physical servers, etc.), or alternatively, each LMF 270 may correspond to a single server. The LMF 270 can be configured to support one or more location services for the UE 204, which is able to connect to the LMF 270 via the core network 5GC 260 and / or via the Internet (not shown). SLP 272 can support similar functions to LMF270, but LMF 270 can communicate with AMF 264, NG-RAN 220 and UE 204 on the control plane (e.g., using interfaces and protocols designed to transmit signaling messages rather than voice or data), while SLP 272 can communicate with UE 204 and external clients (e.g., third-party server 274) on the user plane (e.g., using protocols similar to Transmission Control Protocol (TCP) and / or IP designed to carry voice and / or data).

[0070] Another optional aspect may include a third-party server 274, which can communicate with LMF 270, SLP 272, 5GC 260 (e.g., via AMF 264 and / or UPF 262), NG-RAN 220, and / or UE 204 to obtain location information (e.g., location estimation) of UE 204. Therefore, in some cases, the third-party server 274 may be referred to as a Location Services (LCS) client or an external client. The third-party server 274 may be implemented as multiple separate servers (e.g., physically separate servers, different software modules on a single server, different software modules distributed across multiple physical servers, etc.), or alternatively, each may correspond to a single server.

[0071] User plane interface 263 and control plane interface 265 connect 5GC 260 (specifically UPF 262 and AMF 264, respectively) to one or more gNB 222 and / or ng-eNB 224 in NG-RAN 220. The interface between (multiple) gNB 222 and / or (multiple) ng-eNB 224 and AMF 264 is referred to as the "N2" interface, and the interface between (multiple) gNB 222 and / or (multiple) ng-eNB 224 and UPF 262 is referred to as the "N3" interface. (Multiple) gNB 222 and / or (multiple) ng-eNB 224 in NG-RAN 220 can communicate directly with each other via backhaul connection 223 (referred to as the "Xn-C" interface). One or more of gNB 222 and / or ng-eNB 224 can communicate with one or more UE 204 via a radio interface (referred to as the "Uu" interface).

[0072] The functionality of gNB 222 can be divided among gNB Central Unit (gNB-CU) 226, one or more gNB Distributed Units (gNB-DU) 228, and one or more gNB Radio Units (gNB-RU) 229. gNB-CU 226 is a logical node that includes base station functions such as transmitting user data, mobility control, radio access network sharing, positioning, and session management, in addition to those functions specifically allocated to gNB-DU(multiple) gNB-DU(228) 228. More specifically, gNB-CU 226 typically hosts the Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP) protocols of gNB 222. gNB-DU 228 is a logical node that typically hosts the Radio Link Control (RLC) and Media Access Control (MAC) layers of gNB 222. Its operation is controlled by gNB-CU 226. One gNB-DU 228 can support one or more cells, and a cell is supported by only one gNB-DU 228. The interface 232 between gNB-CU 226 and one or more gNB-DU 228 is referred to as the "F1" interface. The physical (PHY) layer functions of gNB 222 are typically managed by one or more independent gNB-RU 229s, which perform functions such as power amplification and signal transmission / reception. The interface between gNB-DU 228 and gNB-RU 229 is referred to as the "Fx" interface. Therefore, UE 204 communicates with gNB-CU 226 via the RRC, SDAP, and PDCP layers, with gNB-DU 228 via the RLC and MAC layers, and with gNB-RU 229 via the PHY layer.

[0073] Figure 3A , Figure 3B and Figure 3C Several example components (represented by corresponding boxes) are illustrated. These components may be incorporated into UE 302 (which may correspond to any UE described herein), base station 304 (which may correspond to any base station described herein), and network entity 306 (which may correspond to or include any network function described herein, including location server 230 and LMF 270, or alternatively may be independent of UE 302). Figure 2A and Figure 2B The NG-RAN 220 and / or 5GC 210 / 260 infrastructure (such as a private network) depicted herein are used to support the file transfer operations taught herein. It will be understood that, in different implementations, these components can be implemented in different types of devices (e.g., in an ASIC, in a system-on-a-chip (SoC), etc.). The components shown can also be incorporated into other devices in a communication system. For example, other devices in the system may include components similar to those described as providing similar functionality. Similarly, a given device may contain one or more of these components. For example, a device may include multiple transceiver components that enable the device to operate on multiple carriers and / or communicate via different technologies.

[0074] UE 302 and base station 304 each include one or more Wireless Wide Area Network (WWAN) transceivers 310 and 350, which provide components (e.g., components for transmitting, components for receiving, components for measuring, components for tuning, components for suppressing transmission, etc.) for communicating via one or more wireless communication networks (not shown), such as NR networks, LTE networks, GSM networks, etc. WWAN transceivers 310 and 350 may each be connected to one or more antennas 316 and 356 for communicating with other network nodes (such as other UEs, access points, base stations (e.g., eNB, gNB), etc.) via at least one designated RAT (e.g., NR, LTE, GSM, etc.) through a wireless communication medium of interest (e.g., a set of time / frequency resources in a specific spectrum). According to the specified RAT, WWAN transceivers 310 and 350 can be configured differently for transmitting and encoding signals 318 and 358 (e.g., messages, indications, information, etc.) respectively, and conversely for receiving and decoding signals 318 and 358 (e.g., messages, indications, information, pilots, etc.) respectively. Specifically, WWAN transceivers 310 and 350 respectively include one or more transmitters 314 and 354 for transmitting and encoding signals 318 and 358 respectively, and one or more receivers 312 and 352 respectively for receiving and decoding signals 318 and 358 respectively.

[0075] In at least some cases, UE 302 and base station 304 also each include one or more short-range wireless transceivers 320 and 360. The short-range wireless transceivers 320 and 360 can be connected to one or more antennas 326 and 366, respectively, and provide the capability to communicate via a wireless communication medium of interest through at least one designated RAT (e.g., WiFi, LTE-D, etc.). Components (e.g., components for transmitting, components for receiving, components for measuring, components for tuning, components for suppressing transmission, etc.) for communication between PC5, Dedicated Short-Range Communication (DSRC), Wireless Access for Vehicle Environments (WAVE), Near Field Communication (NFC), etc.) and other network nodes (such as other UEs, access points, base stations, etc.). According to the specified RAT, short-range wireless transceivers 320 and 360 can be configured differently for transmitting and encoding signals 328 and 368 (e.g., messages, indications, information, etc.) respectively, and conversely for receiving and decoding signals 328 and 368 (e.g., messages, indications, information, pilots, etc.) respectively. Specifically, short-range wireless transceivers 320 and 360 respectively include one or more transmitters 324 and 364 for transmitting and encoding signals 328 and 368 respectively, and one or more receivers 322 and 362 respectively for receiving and decoding signals 328 and 368 respectively. As specific examples, the short-range wireless transceivers 320 and 360 can be WiFi transceivers, transceiver and / or Transceivers, NFC transceivers, or vehicle-to-vehicle (V2V) and / or vehicle-to-everything (V2X) transceivers.

[0076] In at least some cases, UE 302 and base station 304 also include satellite signal receivers 330 and 370. Satellite signal receivers 330 and 370 may be connected to one or more antennas 336 and 376, respectively, and may provide means for receiving and / or measuring satellite positioning / communication signals 338 and 378, respectively. Where satellite signal receivers 330 and 370 are satellite positioning system receivers, satellite positioning / communication signals 338 and 378 may be Global Positioning System (GPS) signals, Global Navigation Satellite System (GLONASS) signals, Galileo signals, BeiDou signals, Indian Regional Navigation Satellite System (NAVIC), Quasi-Zenith Satellite System (QZSS), etc. Where satellite signal receivers 330 and 370 are non-terrestrial network (NTN) receivers, satellite positioning / communication signals 338 and 378 may be communication signals originating from a 5G network (e.g., carrying control and / or user data). Satellite signal receivers 330 and 370 may include any suitable hardware and / or software for receiving and processing satellite positioning / communication signals 338 and 378, respectively. Satellite signal receivers 330 and 370 may appropriately request information and operations from other systems, and in at least some cases, perform calculations, respectively, using measurements obtained by any suitable satellite positioning system algorithm, to determine the locations of UE 302 and base station 304.

[0077] Base station 304 and network entity 306 each include one or more network transceivers 380 and 390, providing means (e.g., means for transmitting, means for receiving, etc.) for communicating with other network entities (e.g., other base stations 304, other network entities 306). For example, base station 304 may employ one or more network transceivers 380 to communicate with other base stations 304 or network entities 306 via one or more wired or wireless backhaul links. As another example, network entity 306 may employ one or more network transceivers 390 to communicate with one or more base stations 304 via one or more wired or wireless backhaul links, or to communicate with other network entities 306 via one or more wired or wireless core network interfaces.

[0078] Transceivers can be configured to communicate via wired or wireless links. A transceiver (whether wired or wireless) includes transmitter circuitry (e.g., transmitters 314, 324, 354, 364) and receiver circuitry (e.g., receivers 312, 322, 352, 362). In some implementations, the transceiver may be an integrated device (e.g., including transmitter and receiver circuitry in a single device); in some implementations, it may include separate transmitter and receiver circuitry; or in other implementations, it may be included in other ways. The transmitter and receiver circuitry of a wired transceiver (e.g., network transceivers 380 and 390 in some implementations) may be coupled to one or more wired network interface ports. Wireless transmitter circuitry (e.g., transmitters 314, 324, 354, 364) may include or be coupled to multiple antennas (e.g., antennas 316, 326, 356, 366), such as antenna arrays, which allow corresponding devices (e.g., UE 302, base station 304) to perform transmit "beamforming," as described herein. Similarly, wireless receiver circuitry (e.g., receivers 312, 322, 352, 362) may include or be coupled to multiple antennas (e.g., antennas 316, 326, 356, 366), such as antenna arrays, which allow corresponding devices (e.g., UE 302, base station 304) to perform receive beamforming, as described herein. In one aspect, transmitter and receiver circuitry may share the same multiple antennas (e.g., antennas 316, 326, 356, 366), such that the corresponding devices can only receive or transmit at a given time, and cannot receive or transmit simultaneously. Wireless transceivers (e.g., WWAN transceivers 310 and 350, short-range wireless transceivers 320 and 360) may also include network listening modules (NLMs) for performing various measurements.

[0079] As used herein, various wireless transceivers (e.g., transceivers 310, 320, 350, and 360, and network transceivers 380 and 390 in some implementations) and wired transceivers (e.g., network transceivers 380 and 390 in some implementations) may generally be described as "transceiver," "at least one transceiver," or "one or more transceivers." Thus, whether a particular transceiver is wired or wireless can be inferred from the type of communication being performed. For example, backhaul communication between network devices or servers is typically associated with signaling via a wired transceiver, while wireless communication between a UE (e.g., UE 302) and a base station (e.g., base station 304) is typically associated with signaling via a wireless transceiver.

[0080] UE 302, base station 304, and network entity 306 also include other components that can be used with the operations disclosed herein. UE 302, base station 304, and network entity 306 each include one or more processors 332, 384, and 394 for providing functions related to, for example, wireless communication, and for providing other processing functions. Processors 332, 384, and 394 can therefore provide components for processing, such as components for determining, components for calculating, components for receiving, components for transmitting, components for indicating, etc. In one aspect, processors 332, 384, and 394 may include, for example, one or more general-purpose processors, multi-core processors, central processing units (CPUs), ASICs, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), other programmable logic devices or processing circuits, or various combinations thereof.

[0081] UE 302, base station 304, and network entity 306 each include memory circuitry (e.g., each including a memory device) implementing memories 340, 386, and 396 for maintaining information (e.g., information indicating reserved resources, thresholds, parameters, etc.). Memories 340, 386, and 396 can therefore provide components for storage, retrieval, maintenance, etc. In some cases, UE 302, base station 304, and network entity 306 may each include positioning components 342, 388, and 398. Positioning components 342, 388, and 398 may be part of processing systems 332, 384, and 394, respectively, or hardware circuitry coupled to processors 332, 384, and 394, respectively, which, when executed, cause UE 302, base station 304, and network entity 306 to perform the functions described herein. In other respects, positioning components 342, 388, and 398 may be located external to processors 332, 384, and 394 (e.g., as part of a modem processing system, integrated with another processing system, etc.). Alternatively, positioning components 342, 388, and 398 may be memory modules stored in memories 340, 386, and 396, respectively, which, when executed by processors 332, 384, and 394 (or the modem processing system, another processing system, etc.), enable UE 302, base station 304, and network entity 306 to perform the functions described herein. Figure 3A The illustration shows possible locations of the positioning component 342, which may be part of, for example, one or more WWAN transceivers 310, memory 340, one or more processors 332 or any combination thereof, or may be a standalone component. Figure 3B The illustration shows possible locations of the positioning component 388, which may be part of, for example, one or more WWAN transceivers 350, memory 386, one or more processors 384 or any combination thereof, or may be a standalone component. Figure 3C The illustration shows possible locations of the positioning component 398, which may be part of, for example, one or more network transceivers 390, memory 396, one or more processors 394 or any combination thereof, or may be a standalone component.

[0082] UE 302 may include one or more sensors 344 coupled to processing system 332 to provide components for sensing or detecting motion and / or orientation information independent of motion data derived from signals received by one or more WWAN transceivers 310, one or more short-range wireless transceivers 320, and / or satellite signal receivers 330. As an example, the sensors 344 may include accelerometers (e.g., microelectromechanical systems (MEMS) devices), gyroscopes, geomagnetic sensors (e.g., compasses), altimeters (e.g., barometric altimeters), and / or other types of motion detection sensors. Furthermore, the sensors 344 may include multiple different types of devices, and their outputs may be combined to provide motion information. For example, the sensors 344 may use a combination of multi-axis accelerometers and orientation sensors to provide the ability to calculate position in two-dimensional (2D) and / or three-dimensional (3D) coordinate systems.

[0083] In addition, UE 302 includes a user interface 346, providing components for providing instructions to the user (e.g., audible and / or visual instructions) and / or receiving user input (e.g., when the user activates a probing device (such as a keyboard, touchscreen, microphone, etc.)). Although not shown, base station 304 and network entity 306 may also include user interfaces.

[0084] Referring more specifically to one or more processors 384, in the downlink, IP packets from network entity 306 can be provided to processor 384. One or more processors 384 can implement the functions of the RRC layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. One or more processors 384 may provide RRC layer functions associated with broadcasting system information (e.g., Master Information Block (MIB), System Information Block (SIB)), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-RAT mobility, and measurement configuration for UE measurement reporting; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with upper-layer PDU transmission, error correction via Automatic Repeat Request (ARQ), concatenation, segmentation, and reassembly of RLC Service Data Units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, scheduling information reporting, error correction, priority processing, and logical channel prioritization.

[0085] Transmitter 354 and receiver 352 implement Layer 1 (L1) functions associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. Transmitter 354 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The encoded and modulated symbols can then be split into parallel streams. Each stream can then be mapped to orthogonal frequency division multiplexing (OFDM) subcarriers, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domains, and then combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time-domain OFDM symbol stream. The OFDM symbol stream is spatially precoded to generate multiple spatial streams. Channel estimates from the channel estimator can be used to determine the coding and modulation scheme, as well as for spatial processing. Channel estimates can be derived from reference signals transmitted by UE 302 and / or channel condition feedback. Each spatial stream can then be provided to one or more different antennas 356. The transmitter 354 can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0086] At UE 302, receiver 312 receives signals through its respective antenna(s) 316. Receiver 312 recovers the information modulated onto the RF carrier and provides this information to one or more processors 332. Transmitter 314 and receiver 312 implement Layer 1 functions associated with various signal processing functions. Receiver 312 can perform spatial processing on this information to recover any spatial stream destined for UE 302. If multiple spatial streams are destined for UE 302, they can be combined by receiver 312 into a single OFDM symbol stream. Receiver 312 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal comprises separate OFDM symbol streams for each subcarrier of the OFDM signal. Symbols on each subcarrier, along with a reference signal, are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 304. These soft decisions can be based on a channel estimate calculated by a channel estimator. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 304 on the physical channel. The data and control signals are then provided to one or more processors 332, which implement layer 3 (L3) and layer 2 (L2) functions.

[0087] In the uplink, one or more processors 332 provide demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover IP packets from the core network. One or more processors 332 are also responsible for error detection.

[0088] Similar to the functions described in conjunction with downlink transmission of base station 304, one or more processors 332 provide RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with transmission of upper-layer PDUs, error correction via ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs to transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via Hybrid Automatic Repeat Request (HARQ), priority processing, and logical channel priority.

[0089] Transmitter 314 can use channel estimation derived from a reference signal or feedback transmitted by base station 304 by channel estimator to select appropriate coding and modulation schemes and facilitate spatial processing. The spatial stream generated by transmitter 314 can be provided to different(multiple) 316. Transmitter 314 can utilize the corresponding spatial stream to modulate the RF carrier for transmission.

[0090] Uplink transmissions are processed at base station 304 in a manner similar to that described in conjunction with the receiver function at UE 302. Receiver 352 receives signals through its respective antenna(s) 356. Receiver 352 recovers the information modulated onto the RF carrier and provides that information to one or more processors 384.

[0091] In the uplink, one or more processors 384 provide demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover IP packets from UE 302. IP packets from the one or more processors 384 can be provided to the core network. The one or more processors 384 are also responsible for error detection.

[0092] For convenience, UE 302, base station 304 and / or network entity 306 are in Figure 3A , Figure 3B and Figure 3C The diagram shows various components that can be configured according to the various examples described herein. However, it will be understood that the components shown may have different functionalities in different designs. Specifically, Figures 3A to 3C Various components are optional in alternative configurations, and aspects include configurations that may differ due to design choices, cost, equipment usage, or other considerations. For example, in Figure 3A In such cases, a specific implementation of UE 302 may omit (multiple) WWAN transceivers 310 (e.g., wearable devices, tablets, PCs, or laptops may have Wi-Fi and / or Bluetooth capabilities but no cellular capabilities), or may omit (multiple) short-range wireless transceivers 320 (e.g., cellular only), or may omit satellite signal receivers 330, or may omit (multiple) sensors 344, and so on. In another example, in Figure 3B In certain cases, a specific implementation of base station 304 may omit (multiple) WWAN transceivers 350 (e.g., Wi-Fi "hotspot" access points without cellular capabilities), or (multiple) short-range wireless transceivers 360 (e.g., cellular only), or (satellite receiver 370), and so on. For the sake of brevity, descriptions of various alternative configurations are not provided herein, but they will be readily understood by those skilled in the art.

[0093] The various components of UE 302, base station 304, and network entity 306 can be communicatively coupled to each other via data buses 334, 382, ​​and 392, respectively. In one aspect, data buses 334, 382, ​​and 392 can form communication interfaces for UE 302, base station 304, and network entity 306, or can be portions of such communication interfaces. For example, when different logical entities are implemented in the same device (e.g., gNB and location server functions are combined in the same base station 304), data buses 334, 382, ​​and 392 can provide communication between them.

[0094] Figure 3A , Figure 3B and Figure 3C Components can be implemented in various ways. In some implementations, Figure 3A , Figure 3B and Figure 3C The components can be implemented in one or more circuits, such as one or more processors and / or one or more ASICs (which may include one or more processors). Here, each circuit may use and / or incorporate at least one memory component for storing information or executable code used by the circuit to provide the function. For example, some or all of the functions represented by blocks 310 to 346 may be implemented by the processor and(s) memory components of UE 302 (e.g., by executing appropriate code and / or by properly configuring the processor components). Similarly, some or all of the functions represented by blocks 350 to 388 may be implemented by the processor and(s) memory components of base station 304 (e.g., by executing appropriate code and / or by properly configuring the processor components). Likewise, some or all of the functions represented by blocks 390 to 398 may be implemented by the processor and(s) memory components of network entity 306 (e.g., by executing appropriate code and / or by properly configuring the processor components). For simplicity, various operations, behaviors, and / or functions are described herein as being performed "by the UE", "by the base station", "by the network entity", etc. However, it will be understood that these operations, behaviors and / or functions can actually be performed by specific components or combinations of components of the UE 302, base station 304, network entity 306, etc., such as processors 332, 384, 394, transceivers 310, 320, 350 and 360, memories 340, 386 and 396, positioning components 342, 388 and 398, etc.

[0095] In some designs, network entity 306 may be implemented as a core network component. In other designs, network entity 306 may operate differently from the network operator or cellular network infrastructure (e.g., NG RAN 220 and / or 5GC 210 / 260). For example, network entity 306 may be a component of a private network that can be configured to communicate with UE 302 via or independently of base station 304 (e.g., via a non-cellular communication link, such as WiFi).

[0096] NR supports various cellular network-based positioning technologies, including downlink-based, uplink-based, and downlink-and-uplink-based positioning methods. Downlink-based positioning methods include Observed Time Difference of Arrival (OTDOA) in LTE, Downlink Time Difference of Arrival (DL-TDOA) in NR, and Downlink Angle of Departure (DL-AoD) in NR. During OTDOA or DL-TDOA positioning, the UE measures the difference between the times of arrival (ToA) of reference signals (e.g., positioning reference signals (PRS)) received from paired base stations (called the Reference Signal Time Difference (RSTD) or Time Difference of Arrival (TDOA) measurement) and reports them to the positioning entity. More specifically, the UE receives identifiers of a reference base station (e.g., a serving base station) and multiple non-reference base stations in auxiliary data. The UE then measures the RSTD between the reference base station and each non-reference base station. Based on the known locations of the base stations involved and the RSTD measurement, the positioning entity can estimate the UE's location. For DL-AoD positioning, the base station measures the angle of the downlink transmit beam used to communicate with the UE and other channel attributes (e.g., signal strength) to estimate the UE's location.

[0097] Uplink-based positioning methods include uplink time difference of arrival (UL-TDOA) and uplink angle of arrival (UL-AoA). UL-TDOA is similar to DL-TDOA, but is based on uplink reference signals (e.g., SRS) transmitted by the UE. For UL-AoA positioning, the base station measures the angle of the uplink received beam used to communicate with the UE and other channel properties (e.g., gain level) to estimate the UE's location.

[0098] Downlink and uplink-based positioning methods include Enhanced Cell ID (E-CID) positioning and Multiple Round-Trip Time (RTT) positioning (also known as "Multi-Cell RTT"). During RTT, the initiator (base station or UE) sends an RTT measurement signal (e.g., PRS or SRS) to the responder (UE or base station), and the responder sends back an RTT response signal (e.g., SRS or PRS). The RTT response signal includes the difference between the ToA of the RTT measurement signal and the transmission time of the RTT response signal, called the received-transmit (Rx-Tx) measurement. The initiator calculates the difference between the transmission time of the RTT measurement signal and the ToA of the RTT response signal, called the "Tx-Rx" measurement. The propagation time (also known as "time of flight") between the initiator and the responder can be calculated based on the Tx-Rx and Rx-Tx measurements. Based on the propagation time and the known speed of light, the distance between the initiator and the responder can be determined. For multi-RTT positioning, the UE performs the RTT procedure with multiple base stations so that its location can be triangulated based on the known locations of the base stations. RTT and multiple RTT methods can be combined with other positioning technologies, such as UL-AoA and DL-AoD, to improve location accuracy.

[0099] The E-CID positioning method is based on Radio Resource Management (RRM) measurements. In E-CID, the UE reports the serving cell ID, timing advance (TA), and the identifiers, estimated times, and signal strengths of detected neighboring base stations. The UE's location is then estimated based on this information and the known locations of the base stations.

[0100] To assist in positioning operations, a location server (e.g., location server 230, LMF 270, SLP 272) can provide auxiliary data to the UE. For example, auxiliary data may include the identifier of a base station (or its cell / TRP), reference signals measured from that base station (or its cell / TRP), reference signal configuration parameters (e.g., the number of consecutive positioning slots, the periodicity of the positioning slots, silence sequences, frequency hopping sequences, reference signal identifier (ID), reference signal bandwidth, slot offset, etc.), and / or other parameters applicable to a particular positioning method. Alternatively, auxiliary data may be derived directly from the base station itself (e.g., in periodically broadcast overhead messages). In some cases, the UE may be able to detect neighboring network entities independently without using auxiliary data.

[0101] Location estimation can be referred to by other names, such as place estimate, location, location, location fix, etc. A location estimate can be geodetic and include coordinates (e.g., latitude, longitude, and possible altitude), or it can be municipal and include street addresses, postal addresses, or some other verbal description of the location. A location estimate can be further defined relative to some other known location or in absolute terms (e.g., using latitude, longitude, and possible altitude). A location estimate can include anticipated errors or uncertainties (e.g., by including an area or volume within which the location is expected to be included at some specified or default confidence level).

[0102] Various frame structures can be used to support downlink and uplink transmissions between network entities (e.g., base stations and UEs).

[0103] Figure 4A Figure 400 is an example illustrating a downlink frame structure according to various aspects of this disclosure.

[0104] Figure 4B Figure 430 illustrates an example of a channel within a downlink frame structure according to various aspects of this disclosure. Other wireless communication technologies may have different frame structures and / or different channels.

[0105] LTE (and in some cases NR) uses OFDM on the downlink and single-carrier frequency division multiplexing (SC-FDM) on the uplink. However, unlike LTE, NR can also choose to use OFDM on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are often also called tones, bins, etc. Each subcarrier can be modulated with data. Typically, modulation symbols are transmitted using OFDM in the frequency domain and SC-FDM in the time domain. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the subcarrier spacing can be 15 kHz, and the minimum resource allocation (resource block) can be 12 subcarriers (or 180 kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, the nominal FFT size could be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth can also be divided into subbands. For example, a subband can cover 1.8MHz (i.e., 6 resource blocks), and for system bandwidths of 1.25, 2.5, 5, 10, or 20MHz, there can be 1, 2, 4, 8, or 16 subbands respectively.

[0106] LTE supports a single set of parameters (numerology) (subcarrier spacing, symbol length, etc.). In contrast, NR can support multiple sets of parameters (μ), for example, subcarriers of 15kHz, 30kHz, 60kHz, 120kHz, and 240kHz or greater can be available. Table 1 below lists some of the different parameters for different NR parameter sets.

[0107]

[0108] Table 1

[0109] exist Figure 4A and Figure 4B In the example, a parameter set of 15kHz was used. Therefore, in the time domain, a 10-millisecond (ms) frame is divided into 10 equally sized subframes, each 1 ms, and each subframe includes a time slot. Figure 4A and Figure 4B In this representation, time is expressed horizontally as time increases from left to right (e.g., on the X-axis), while frequency is expressed vertically as frequency increases (or decreases) from bottom to top (e.g., on the Y-axis).

[0110] A resource grid can be used to represent time slots, each time slot comprising one or more concurrent resource blocks (RBs) (also known as physical RBs (PRBs)) in the frequency domain. The resource grid is further divided into multiple resource elements (REs). An RE can correspond to a symbol length in the time domain and a subcarrier in the frequency domain. Figure 4A and Figure 4B In the parameter set, for a normal cyclic prefix, the RB can contain 12 consecutive subcarriers in the frequency domain and 7 consecutive symbols in the time domain, for a total of 84 REs. For an extended cyclic prefix, the RB can contain 12 consecutive subcarriers in the frequency domain and 6 consecutive symbols in the time domain, for a total of 72 REs. The number of bits carried by each RE depends on the modulation scheme.

[0111] Some REs carry downlink reference (pilot) signals (DL-RS). DL-RS may include PRS, TRS, PTRS, CRS, CSI-RS, DMRS, PSS, SSS, SSB, etc. Figure 4A An exemplary location of an RE carrying a PRS (labeled "R") is illustrated.

[0112] The set of resource elements (REs) used to transmit PRS is called a "PRS resource". The set of resource elements can span multiple PRBs in the frequency domain and 'N' (e.g., one or more) consecutive symbols within a time slot in the time domain. In a given OFDM symbol in the time domain, the PRS resource occupies a consecutive PRB in the frequency domain.

[0113] The transmission of PRS resources within a given PRB has a specific comb size (also known as "comb density"). The comb size 'N' represents the subcarrier spacing (or frequency / modulation spacing) within each symbol of the PRS resource configuration. Specifically, for a comb size 'N', the PRS is transmitted in every Nth subcarrier of a symbol in the PRB. For example, for comb-4, for each fourth symbol of the PRS resource configuration, the RE corresponding to every fourth subcarrier (e.g., subcarriers 0, 4, 8) is used to transmit the PRS of the PRS resource. Currently, comb sizes of comb-2, comb-4, comb-6, and comb-12 are supported for DL-PRS. Figure 4A The illustration shows an exemplary PRS resource configuration for Comb-6 (which spans six symbols). That is, the position of the shaded REs (labeled "R") indicates the Comb-6 PRS resource configuration.

[0114] A “PRS resource set” is a collection of PRS resources used for PRS signal transmission, where each PRS resource has a PRS resource ID. Furthermore, PRS resources in a PRS resource set are associated with the same TRP. A PRS resource set is identified by a PRS resource set ID and associated with a specific TRP (e.g., identified by a TRP ID). Additionally, PRS resources in a PRS resource set share the same periodicity, a common silence mode configuration, and the same repetition factor (e.g., PRS-ResourceRepetitionFactor) across time slots. Periodicity refers to the time from the first repetition of a first PRS resource in a first PRS instance to the same first repetition of the same first PRS resource in the next PRS instance. The period can have a value selected from 2... μ The lengths of time slots {4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320, 640, 1280, 2560, 5120, 10240} are given, where μ = 0, 1, 2, 3. The repetition coefficients can have lengths selected from time slots {1, 2, 4, 6, 8, 16, 32}.

[0115] In a PRS resource set, the PRS resource ID is associated with a single beam (or beam ID) transmitted from a single TRP (where the TRP can transmit one or more beams). That is, each PRS resource in a PRS resource set can be transmitted on a different beam, and therefore a "PRS resource" or simply a "resource" can also be referred to as a "beam." It should be noted that this has no effect on whether the UE knows the TRP and the beam transmitting the PRS.

[0116] A “PRS instance” or “PRS timing” is an instance of a periodic recurring time window (e.g., a set of one or more consecutive time slots) in which a PRS is expected to be sent. A PRS timing may also be referred to as a “PRS positioning timing,” “PRS positioning instance,” “positioning timing,” “positioning instance,” “positioning repetition,” or simply “timing,” “instance,” or “repetition.”

[0117] A “positioning frequency layer” (also simply “frequency layer”) is a collection of one or more PRS resource sets spanning one or more TRPs (with some parameters having the same value). Specifically, a collection of PRS resource sets has the same subcarrier spacing (SCS) and cyclic prefix (CP) type (meaning all parameter sets supported for PDSCH are also supported for PRS), the same point A, the same downlink PRS bandwidth value, the same starting PRB (and center frequency), and the same comb size. The point A parameter takes the value of the parameter ARFCN-ValueNR (where “ARFCN” stands for “absolute radio channel number”) and is an identifier / code that specifies a pair of physical radio channels used for transmission and reception. The downlink PRS bandwidth can have a granularity of four PRBs, with a minimum of 24 PRBs and a maximum of 272 PRBs. Currently, up to four frequency layers have been defined, and each TRP of each frequency layer can be configured with up to two PRS resource sets.

[0118] The concept of a frequency layer is similar to that of component carriers and bandwidth portions (BWPs), but the difference is that component carriers and BWPs are used by a single base station (or a macro cell base station and a small cell base station) to transmit data channels, while a frequency layer is used by several (usually three or more) base stations to transmit PRS (Positioning Signals). When a UE transmits its positioning capabilities to the network (such as during an LTE Positioning Protocol (LPP) session), it can indicate the number of frequency layers it can support. For example, a UE can indicate whether it can support one or four positioning frequency layers.

[0119] Figure 4B The diagram illustrates examples of various channels within a downlink time slot of a radio frame. In NR, channel bandwidth, or system bandwidth, is divided into multiple BWPs. A BWP is a contiguous set of PRBs, which are contiguous subsets of common RBs selected from a specific set of parameters on a particular carrier. Generally, a maximum of four BWPs can be specified in both the downlink and uplink. That is, a UE can be configured with a maximum of four BWPs in the downlink and a maximum of four BWPs in the uplink. At any given time, only one BWP (uplink or downlink) can be active, meaning the UE can only receive or transmit through one BWP at a time. In the downlink, the bandwidth of each BWP should be equal to or greater than the bandwidth of the SSB, but it may or may not contain the SSB.

[0120] refer to Figure 4B The Primary Synchronization Signal (PSS) is used by the UE to determine subframe / symbol timing and physical layer identifiers. The UE uses the Secondary Synchronization Signal (SSS) to determine the physical layer cell identifier group number and radio frame timing. Based on the physical layer identifier and physical layer cell identifier group number, the UE can determine the PCI. Based on the PCI, the UE can determine the location of the aforementioned DL-RS. The Physical Broadcast Channel (PBCH) carrying the MIB can logically be grouped with the PSS and SSS to form the SSB (also known as SS / PBCH). The MIB provides the number of RBs and the System Frame Number (SFN) in the downlink system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data and broadcast system information not transmitted via the PBCH, such as System Information Blocks (SIBs) and paging messages.

[0121] The Physical Downlink Control Channel (PDCCH) carries downlink control information (DCI) within one or more Control Channel Elements (CCEs). Each CCE includes one or more RE Group (REG) bundles (which can span multiple symbols in the time domain). Each REG bundle contains one or more REGs, and each REG corresponds to 12 resource elements (one resource block) in the frequency domain and one OFDM symbol in the time domain. The physical resource set used to carry the PDCCH / DCI is called the Control Resource Set (CORESET) in NR. In NR, the PDCCH is restricted to a single CORESET and transmitted along with its own DMRS. This enables UE-specific beamforming for the PDCCH.

[0122] exist Figure 4B In the example, each BWP has a CORESET, and the CORESET spans three symbols in the time domain (although it may only have one or two symbols). Unlike the LTE control channel, which occupies the entire system bandwidth, in NR, the PDCCH channel is located in a specific region (i.e., the CORESET) in the frequency domain. Therefore, Figure 4B The frequency components of the PDCCH shown are represented in the frequency domain as less than a single BWP. It should be noted that although the CORESET shown is continuous in the frequency domain, it does not have to be. Furthermore, the CORESET can span less than three symbols in the time domain.

[0123] The DCI within the PDCCH carries information about uplink resource allocation (persistent and non-persistent) and a description of the downlink data sent to the UE. Multiple (e.g., up to eight) DCIs can be configured in the PDCCH, and these DCIs can have one of several formats. For example, there are different DCI formats for uplink scheduling, non-MIMO downlink scheduling, MIMO downlink scheduling, and uplink power control. The PDCCH can be transmitted by 1, 2, 4, 8, or 16 CCEs to accommodate different DCI payload sizes or coding rates.

[0124] Figure 5 This diagram illustrates how the parameters of the measurement gap configuration 500, according to various aspects of this disclosure, specify the mode of the measurement gap 502. The measurement gap offset (MGO) is the offset between the start of the gap mode and the start of a time slot or subframe within the measurement gap repetition period (MGRP). Currently, there are approximately 160 offset values, but not all values ​​apply to all periods. More specifically, the offset values ​​range from '0' to 1 less than MGRP. Therefore, for example, if MGRP is 20 ms, the offset range can be from '0' to '19'. The measurement gap length (MGL) is the length of the measurement gap in milliseconds. The measurement gap length can have values ​​of 1.5 ms, 3 ms, 3.5 ms, 4 ms, 5.5 ms, or 6 ms. MGRP defines the repetition period (in milliseconds) of the measurement gap 502. It can have values ​​of 20 ms, 40 ms, 80 ms, or 160 ms. Although in Figure 5 As not shown, the measurement gap configuration 500 may also include a measurement gap timing advance (MGTA) parameter. If configured, the MGTA indicates the amount of time before the measurement gap 502 is configured to begin, or before the occurrence of a subframe. Currently, the MGTA for FR2 can be 0.25 ms, and the MGTA for FR1 can be 0.5 ms.

[0125] Currently, the introduction of additional MG modes with MGL ≥ 10ms and MGRP ≥ 80ms is under discussion. It has not yet been decided whether the new MG modes are suitable for RRM measurements, and details of the new MG modes have not been specified. Candidate values ​​for MGL include 10ms, 18ms, 20ms, 34ms, 40ms, and 50ms. Candidate values ​​for MGRP include 80ms, 160ms, 320ms, and 640ms. The combined values ​​of MGL and MGRP have not yet been specified, but combinations under discussion include MGL = 40ms and MGRP = 160ms, MGL = 34ms and MGRP = 160ms, and MGL = 18ms and MGRP = 160ms.

[0126] Figure 6The diagram illustrates the PRS signals, marked PRS1 to PRS2, transmitted within the PRS timing interval 602 in measurement gap 502. N The diagram shows the positioning reference signal 600. PRS1 is associated with a transmit / receive point (TRP), PRS2 with another TRP, and so on. Figure 6 In this configuration, each PRS is repeated four times, and the transmission of each PRS immediately follows the transmission of the next PRS in the time domain; for example, the PRS is "tightly packed" in the time domain. For each repetition, each TRP can use the same beam pattern or a different beam pattern. Figure 6 In this context, the PRS is transmitted throughout the entire duration of PRS timing 602, and PRS timing 602 only occupies a portion of measurement gap 502, but other configurations are also contemplated in this disclosure. Up to 256 TRPs can be configured using auxiliary data, meaning the UE may require longer measurement gaps to measure the PRS from all TRPs. These longer intervals need to be tracked periodically for use cases, and the longer intervals will impact NR throughput. In 3GPP Release 17 (Rel17), there is a provision for using the Tracking Reference Signal (TRS) as a positioning signal; the TRS is the NR signal used for tracking. Figure 7 An example TRS configuration is shown in the figure.

[0127] Figure 7 This diagram illustrates the tracking reference signals 700, labeled TRS1 to TRS4, ​​transmitted within the TRS timing 702 of the measurement gap 502. TRS1 is associated with one transmit / receive point (TRP), TRS2 with another TRP, and so on. Figure 7 The diagram shows TRS from four different cells, but other numbers of cells are expected. TRS can be used individually or in conjunction with PRS. For a given time slot, each TRS occupies four OFDM symbols, although different frequency offsets can be used on a single symbol to make the TRS appear as a 4-symbol comb-4 signal. TRS from different cells will not be tightly packed together, and each cell will have a different TRS offset. Figure 7 In this process, each TRS is repeated four times, and the transmission of the next TRS is not immediately followed in the time domain; for example, TRS are “sparsely packed” in the time domain. The UE will require long measurement intervals to measure long TRS timings 702.

[0128] Therefore, a technical challenge for UEs operating in networks supporting numerous PRS or TRS is that the corresponding PRS or TRS timings must be long enough to cover that duration, requiring at least an equally long measurement gap. However, long measurement gaps reduce NR throughput and increase UE power consumption.

[0129] To address these technical challenges, the following solution is proposed: allowing multiple measurement gap (MG) configurations to be configured for each tracking session, and providing a mechanism by which the UE can dynamically change the size and / or location of the MG. In some aspects, the size and / or location of the MG can be set based on the characteristics of the PRS or TRS signals measured by the UE. For example, the UE can narrow the MG to focus on several PRS and / or TRS signals with high quality. Narrower MG reduces the time the UE must spend listening to the PRS, resulting in lower UE power consumption and longer battery life, as well as allowing more time for data transmission, which increases throughput. For on-demand PRS, this solution can be used to improve PRS overhead, for example, by reducing the number of PRS that the UE needs to decode in tracking mode. Another advantage is that the location server / gNB can stop scheduling PRS outside of the requested MG, which will improve overall system throughput. Yet another advantage is that when the base station provides multiple MG configurations to the UE, these MG configurations can be broadcast or multicast.

[0130] Figure 8 The illustration shows an example of multiple measurement gaps based on several aspects. (It can be described as configuring multiple measurement gaps, or it can be described as having a configuration with multiple measurement gaps). Figure 8 This diagram illustrates PRS / TRS timing 800, which includes multiple PRS and / or TRS measurements and four measurement gaps labeled MG1, MG2, MG3, and MG4. Each measurement gap has a different combination of MGL and MGO values. Some MGs (such as MG1 and MG2) may have the same MGO value but different MGL values. Other MGs (such as MG2 and MG3) may have the same MGL value but different MGO values. Figure 8 In the example shown, MG1 covers the entire PRS / TRS period 800 and beyond; MG2 covers PRS1 to PRS3, MG3 covers PRS6 to PRS8, and MG3 covers PRS3 to PRS6. In some respects, MGs can be associated with a reference cell used for measurement reporting. For example, when MG1 is used, the UE can transmit measurement reports to the cell associated with PRS1, but when MG3 is used, PRS1 is not within the measurement interval, so the UE can transmit measurement reports to the cell associated with PRS8. Figure 8 This is illustrative rather than restrictive: therefore, the number, length, and offset of various measurement gaps can vary and still remain within the scope of the concepts presented herein.

[0131] Figure 9A and Figure 9BThis is a signal message transmission diagram illustrating a portion of an exemplary method 900 for wireless communication according to various aspects. Figure 9A and Figure 9B The interaction between UE 302, base station 304 and network entity (NE) 306 is illustrated. In some respects, NE 306 may be an entity on a core network (e.g., core network 170), and in some respects may be or include location server 172.

[0132] exist Figure 9A In the sequence, at position 902, UE 302, BS 304, and NE 306 initiate a location session, and at position 904, NE 306 provides PRS configuration to UE 302. Optionally, at position 906, UE 302 is provided with multiple measurement gap (MG) configurations, labeled MG1, MG2, MG3, etc. For illustrative purposes, data from... Figure 8 The measuring gaps are configured as MG1, MG2, MG3, and MG4. Although for the sake of simplicity in explanation... Figure 9A and 9B The example shown refers to PRS, but the same concept can be applied to TRS or a combination of PRS and TRS. In some respects, multiple MG configurations can be broadcast or ensembled to multiple UEs.

[0133] At 908, UE 302 sends a request to BS 304 to use the measurement gap using MG1. For example, UE 302 requests to use a measurement gap spanning all PRS during PRS timing. At 910, BS 304 sends an MG response instructing UE 302 to use MG1. In this exchange, BS 304 allows UE 302 to use the requested MG configuration, but this is not always the case. At 912, UE 302 measures PRS1 through PRS8, and at 914, UE 302 determines that PRS1 through PRS3 have good signals and PRS4 through PRS8 have poor signals (or UE 302 determines that PRS1 through PRS3 have better signals than the other PRSs).

[0134] At 916, UE 302 transmits a measurement gap request to use MG2; for example, UE 302 requests to use a measurement gap spanning PRS1 to PRS3 but not PRS4 to PRS8. At 918, BS 304 transmits an MG response instructing UE 302 to use MG2. Starting at 920, UE 302 measures PRS1 to PRS3 but not PRS4 to PRS8. By measuring a subset of PRS less than all PRSs during the PRS timing, UE 302 can reduce its power consumption and / or increase its throughput. UE 302 continues to use MG2 as long as it is valid, for example, until MG2 expires.

[0135] At 922, MG2 expires. MG2 can expire after a set duration, after a threshold number of PRS measurements have been performed, in response to some other triggering conditions, or a combination of the above. In some respects, when MG2 expires, UE 302 returns to the default measurement interval configuration, such as MG1. Therefore, in Figure 9A In the sequence, at 924, UE 302 sends an MG request to BS 304 to use MG1, and at 926, BS 304 grants the request. Starting at 928, UE 302 again measures all PRSs, namely PRS1 to PRS8, during the PRS timing.

[0136] exist Figure 9A In the example shown, each MG can be associated with a timer that determines when to stop using the MG. In some respects, a default MG can be associated with a timer that determines when to start or restart using the default MG, regardless of how long another measurement gap configuration has been active. In some respects, this can be a periodic timer, which can be triggered by some triggering events, or a combination thereof.

[0137] exist Figure 9B In step 930, UE 302 determines that PRS7 and PRS8 have better signals than other PRSs (or have signals while other PRSs do not), and therefore at 932, UE 302 sends an MG request to BS 304 to use MG3, meaning UE 302 will use the measurement gap spanning PRS7 to PRS9 and not spanning PRS1 to PRS6. At 934, BS 304 responds with an indication that UE 302 should use MG4 instead of the requested MG3. From 936 until MG4 expires, UE 302 measures PRS4 to PRS6. Figure 9B The illustration shows a point where UE 302 may not always obtain the MG configuration it requests.

[0138] Furthermore, there may be a situation where UE 302 finds no available PRS signal with acceptable signal quality. For example, at 938, UE 302 does not find a good PRS signal. In some respects, UE 302 may determine that it is not using an MG configuration with the best chance of detecting a good PRS (e.g., with the widest measurement gap or covering the largest number of PRSs). In this case, at 940, UE 302 may optionally negotiate with base station 304 to change to an MG configuration with the best chance of detecting a good PRS, such as MG0 in this example. At 942, UE 302 may optionally re-measure using the changed MG configuration. Figure 9BIn the example above, UE 302 still cannot find a PRS signal with acceptable signal quality. Therefore, at 944, UE 302 can request a new MG configuration set, and at 946, BS 304 provides UE 302 with the new MG configuration set, i.e., at least one of the MG configurations in the new set is different from the configuration in the old set. Figure 9B In the example shown, the new MG configuration defines five new MGs, MG5 through MG9. In some respects, the new MG configuration can be broadcast or multicast to multiple UEs, for example, to other UEs in the same area, or to other UEs that also failed to find an acceptable PRS using their current MG configurations. At 948, UE 302 sends an MG request to BS 304 to use one of the multiple MGs (e.g., MG5), which can be the MG with the widest span, and at 950, BS 304 grants the request. Figure 9B In the example shown, MG5 spans a new PRS set, such as PRS9 to PRS. 16 Alternatively, the new MG configuration can define different MGs spanning different groups of existing PRSs instead of the new PRS set, or different MGs spanning a mixture of previously used PRSs and new PRSs. At 952, UE 302 measures PRS9 to PRS. 16 .

[0139] There are multiple metrics that UE 302 can use to identify a good PRS. For example, a good PRS or TRS can be identified based on signal strength (e.g., RSRP, SINR, etc.), the quality of timing measurements based on PRS or TRS, and / or based on dilution of precision (DOP) metrics. For example, if UE 302 only measures a subset of PRS or TRS that are geographically co-located or otherwise do not provide sufficiently geographically distinct signals, thus reducing the accuracy of location calculation, UE 302 may choose not to limit itself to measuring only that subset, for fear of diminishing the accuracy of the positioning activity.

[0140] Figure 10A and Figure 10B This is a flowchart illustrating a portion of an example process 1000 associated with the dynamic configuration of the measurement gap according to various aspects of this disclosure. In some implementations, Figure 10A and Figure 10B One or more processing blocks can be executed by a user equipment (UE) (e.g., UE 104). In some implementations, Figure 10A and Figure 10B One or more processing blocks can be executed by another device or a group of devices that are separate from or include the UE. Additionally or alternatively, Figure 10A and Figure 10B One or more processing blocks may be executed by one or more components of UE 302, such as processor(s) 332, memory 340, WWAN transceiver(s) 310, short-range wireless transceiver(s) 320, satellite signal receiver 330, sensor(s) 344, user interface 346, and positioning component(s) 342, any or all of which may be components for performing the operations of process 1000.

[0141] like Figure 10A As shown, process 1000 may include determining a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs, each MG having a measurement gap length (MGL) and a measurement gap offset (MGO) (box 1002). Components for performing the operations of box 1002 may include processor(s) 332, memory 340, or WWAN transceiver(s) 310 of UE 302. For example, in some aspects, determining the plurality of MG configurations includes, for example, receiving the plurality of MG configurations from a base station or from a core network entity (such as an LMS or LMF) via transceiver(s) 312. In some aspects, determining the plurality of MG configurations includes receiving the plurality of MG configurations via RRC signaling.

[0142] like Figure 10A As further illustrated, process 1000 may include transmitting a first request (block 1004) to the serving base station using a first MG configuration from multiple MG configurations. Components for performing the operations of block 1004 may include multiple processors 332, memory 340, or multiple WWAN transceivers 310 of UE 302. For example, UE 302 may use multiple transmitters 314 to transmit the first request.

[0143] like Figure 10A As further illustrated, process 1000 may include receiving a response to the first request from a serving base station or from a core network entity such as an LMS or LMF (block 1006). Components for performing the operations of block 1006 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312(s) to receive the response to the first request. The response to the request will indicate the MG configuration that the UE should use. In some respects, the MG configuration indicated by the response to the first request may be the same as or different from the first MG configuration. That is, the MG configuration that the UE should use may be the MG configuration requested by the UE, or it may not be the MG configuration requested by the UE.

[0144] like Figure 10AAs further illustrated, process 1000 may include measuring a first set of location signals using an MG configuration indicated by a response to a first request (block 1008). Components for performing the operation of block 1008 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of the UE 302. For example, the UE may use receiver(s) 312(s) to measure the first set of location signals.

[0145] like Figure 10A As further illustrated, process 1000 may include selecting a second MG configuration from a plurality of MG configurations based on measurements of a first set of positioning signals (block 1010). Components for performing the operation of block 1010 may include processor(s) 332, memory 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use processor(s) 332 to select a second MG configuration from a plurality of MG configurations stored in memory 340 based on measurements of the first set of positioning signals made by receiver(s) 312.

[0146] In some aspects, selecting a second MG configuration from multiple MG configurations based on measurements of a first set of positioning signals includes: identifying a first subset of positioning signals from the first set of positioning signals based on a quality metric; and selecting a second MG configuration from multiple MG configurations based on the first subset of positioning signals. In some aspects, the quality metric includes a reference signal received power (RSRP) value, a reference signal received quality (RSRQ) value, a signal-to-interference-plus-noise ratio (SINR) value, the quality of timing measurements, an accuracy attenuation metric, or various combinations thereof.

[0147] In some aspects, the first subset of positioning signals satisfies a quality metric, and selecting a second MG configuration based on the first subset of positioning signals includes selecting an MG configuration having MGs that include the first subset of positioning signals. In some aspects, selecting an MG configuration having MGs that include the first subset of positioning signals includes selecting an MG configuration having the minimum MG that includes the first subset of positioning signals.

[0148] In some aspects, the first subset of positioning signals fails to meet quality metrics, and selecting a second MG configuration based on the first subset of positioning signals includes selecting an MG configuration that excludes MGs from the first subset of positioning signals. In some aspects, selecting an MG configuration that includes MGs from the first subset of positioning signals includes selecting an MG configuration that includes the largest MG that excludes the first subset of positioning signals.

[0149] like Figure 10AAs further illustrated, process 1000 may include transmitting a second request (block 1012) to the serving base station using a second MG configuration from multiple MG configurations. Components for performing the operations of block 1012 may include multiple processors 332, memory 340, or multiple WWAN transceivers 310 of the UE 302. For example, the UE may use multiple transmitters 314 to transmit the second request. In some aspects, the second MG configuration indicates a reference cell for measurement reporting, and the method further includes transmitting a measurement report to the reference cell indicated by the second MG configuration. Figure 8 In the example shown, when MG configuration MG4 is selected, the UE can send measurement reports to the cell associated with PRS4 instead of the default cell, which in this example is the cell associated with PRS1.

[0150] like Figure 10A As further illustrated, process 1000 may include receiving a response to the second request from the serving base station (block 1014). Components for performing the operations of block 1014 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of the UE 302. For example, the UE 302 may use receiver(s) 312(s) to receive the response to the second request. In some aspects, the MG configuration indicated by the response to the second request may be the same as or different from the second MG configuration. That is, the MG configuration to be used by the UE may or may not be the second MG configuration requested by the UE.

[0151] like Figure 10A As further illustrated, process 1000 may include measuring a second set of location signals using an MG configuration indicated by a response to a second request (block 1016). Components for performing the operations of block 1016 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312(s) to measure the second set of location signals.

[0152] In some aspects, at least one positioning signal in at least one set of the first positioning signal set or the second positioning signal set includes a positioning reference signal (PRS) or a tracking reference signal (TRS).

[0153] like Figure 10BAs shown, in some aspects, process 1000 may further include detecting a first trigger condition (block 1018). Components for performing the operations of block 1018 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use processor(s) 332 to detect an internal trigger condition, or may use receiver(s) 312 to detect an external trigger condition. In some aspects, detecting the first trigger condition includes: detecting that a time limit for using the second MG configuration has expired; detecting that a threshold number of measurements using the second MG configuration has been met; or receiving an instruction to stop using the second MG configuration.

[0154] like Figure 10B As further illustrated, process 1000 may also include transmitting a request to the serving base station to use a default MG configuration from multiple MG configurations, the default MG configuration defining a default MG (block 1020). Components for performing the operations of block 1020 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of the UE 302. For example, the UE may use transmitter(s) 314 to transmit the request.

[0155] like Figure 10B As further illustrated, process 1000 may also include receiving a response from the serving base station to a request for using the default MG configuration (block 1022). Components for performing the operation of block 1022 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312 to receive the response.

[0156] like Figure 10B As further illustrated, process 1000 may also include measuring a third location signal set using an MG configuration indicated by a response to a request to use a default MG configuration (block 1024). Components for performing the operations of block 1024 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312(s) to measure the third location signal set. In some aspects, the default MG configuration includes a first MG configuration, the default MG includes the first MG, and the third location signal set includes the first location signal set.

[0157] The process of identifying a subset of location signals, selecting a MG that covers only those location signals, and using that MG until instructed to return to the default MG can be repeated indefinitely, for example, by returning to... Figure 10A Point A in the flowchart.

[0158] Process 1000 may include additional implementations, such as any single implementation or any combination of implementations described below and / or in conjunction with one or more other processes described elsewhere herein. While Figure 10 shows example blocks of process 1000, in some implementations, process 1000 may include additional blocks, fewer blocks, different blocks, or different arrangements of blocks compared to those shown in Figure 10. Additionally or alternatively, two or more blocks of process 1000 may be executed in parallel.

[0159] Figure 11A , Figure 11B and Figure 11C This is a flowchart illustrating a portion of an example process 1100 associated with the dynamic configuration of the measurement gap according to various aspects of this disclosure. In some implementations, Figures 11A to 11C One or more processing blocks can be executed by the UE (e.g., UE 104). In some implementations, Figures 11A to 11C One or more processing blocks can be executed by another device or a group of devices that are separate from or include the UE. Additionally or alternatively, Figures 11A to 11C One or more processing blocks may be executed by one or more components of UE 302, such as processor(s) 332, memory 340, WWAN transceiver(s) 310, short-range wireless transceiver(s) 320, satellite signal receiver 330, sensor(s) 344, user interface 346, and positioning component(s) 342, any or all of which may be components for performing the operations of process 1100.

[0160] like Figure 11A As shown, process 1100 may include determining a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs, each MG having a measurement gap length (MGL) and a measurement gap offset (MGO), and indicating a reference cell for measurement reporting (box 1102). Components for performing the operations of box 1102 may include processor(s) 332, memory 340, or WWAN transceiver(s) 310 of UE 302. For example, in some aspects, determining the plurality of MG configurations includes, for example, receiving the plurality of MG configurations from a base station or from a core network entity (such as an LMS or LMF) via transceiver(s) 312. In some aspects, determining the plurality of MG configurations includes receiving the plurality of MG configurations via RRC signaling.

[0161] like Figure 11AAs further illustrated, process 1100 may include measuring a first set of positioning signals using one of a plurality of MG configurations (block 1104). Components for performing the operations of block 1104 may include a plurality of processors 332, a memory 340, or a plurality of WWAN transceivers 310 of the UE 302. For example, the UE 302 may use a plurality of receivers 312 to measure the first set of positioning signals.

[0162] like Figure 11A As further illustrated, process 1100 may include reporting measurements to a reference cell for a measurement report indicated by an MG configuration (block 1106). Components for performing the operations of block 1106 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use transmitter(s) 314 to report measurements.

[0163] like Figure 11B As shown, in some aspects, process 1100 may also include transmitting a second request (block 1108) to the serving base station using a second MG configuration from multiple MG configurations. Components for performing the operation of block 1108 may include multiple processors 332, memory 340, or multiple WWAN transceivers 310 of UE 302. For example, UE 302 may use multiple transmitters 314 to transmit the second request.

[0164] In some aspects, transmitting the second request includes selecting a second MG configuration from a plurality of MG configurations based on measurements of the first set of positioning signals.

[0165] In some aspects, selecting a second MG configuration from multiple MG configurations based on measurements of a first set of positioning signals includes: identifying a first subset of positioning signals from the first set of positioning signals based on a quality metric; and selecting a second MG configuration from multiple MG configurations based on the first subset of positioning signals.

[0166] In some respects, quality metrics include the Reference Signal Received Power (RSRP) value, the Reference Signal Received Quality (RSRQ) value, the Signal-to-Interference-plus-Noise Ratio (SINR) value, the quality of timing measurements, accuracy attenuation metrics, or various combinations thereof.

[0167] In some respects, the first subset of positioning signals satisfies a quality metric, and the selection of a second MG configuration based on the first subset of positioning signals includes selecting an MG configuration having an MG that includes the first subset of positioning signals.

[0168] In some respects, selecting an MG configuration having an MG that includes a first subset of positioning signals includes selecting an MG configuration having a minimum MG that includes a first subset of positioning signals.

[0169] In some respects, the first subset of positioning signals fails to meet quality metrics, and the selection of a second MG configuration based on the first subset of positioning signals includes selecting an MG configuration that excludes MGs from the first subset of positioning signals.

[0170] In some respects, selecting an MG configuration that includes a subset of the first positioning signals includes selecting an MG configuration that excludes the largest MG from the first subset of positioning signals.

[0171] like Figure 11B As further illustrated, process 1100 may include receiving a response to the second request from the serving base station (block 1110). Components for performing the operations of block 1110 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312 to receive a response to the second request.

[0172] like Figure 11B As further illustrated, process 1100 may include measuring a second set of location signals using the MG configuration indicated by the response to the second request (block 1112). Components for performing the operation of block 1112 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312 to measure the second set of location signals.

[0173] like Figure 11B As further illustrated, process 1100 may include reporting measurements to a reference cell for a measurement report indicated by the MG configuration in response to the second request (block 1114). Components for performing the operations of block 1114 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use transmitter(s) 314 to report measurements.

[0174] In some respects, one of the multiple MG configurations is identified as the default MG configuration.

[0175] like Figure 11CAs shown, in some aspects, process 1100 may further include detecting a first trigger condition (block 1116). Components for performing the operations of block 1116 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use processor(s) 332 to detect an internal trigger condition, or may use receiver(s) 312 to detect an external trigger condition. In some aspects, detecting the first trigger condition includes: detecting that a time limit for using the second MG configuration has expired; detecting that a threshold number of measurements using the second MG configuration has been met; or receiving an instruction to stop using the second MG configuration.

[0176] like Figure 11C As further illustrated, process 1100 may also include transmitting a request to the serving base station to use a default MG configuration from multiple MG configurations, the default MG configuration defining a default MG (block 1118). Components for performing the operations of block 1118 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of the UE 302. For example, the UE may use transmitter(s) 314 to transmit the request.

[0177] like Figure 11C As further shown, process 1100 may also include receiving a response from the serving base station to a request for using the default MG configuration (block 1120). Components for performing the operations of block 1120 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312 to receive the response.

[0178] like Figure 11C As further illustrated, process 1100 may also include measuring a third location signal set using an MG configuration indicated by a response to a request to use a default MG configuration (block 1122). Components for performing the operations of block 1122 may include processor(s) 332, memory(s) 340, or WWAN transceiver(s) 310 of UE 302. For example, UE 302 may use receiver(s) 312(s) to measure the third location signal set. In some aspects, the default MG configuration includes a first MG configuration, the default MG includes the first MG, and the third location signal set includes the first location signal set.

[0179] Process 1100 may include additional implementations, such as any single implementation or any combination of implementations described below and / or in conjunction with one or more other processes described elsewhere herein.
