DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The following description is directed to several implementations for the purposes of illustrating the inventive aspects of various embodiments, however, those skilled in the art will readily recognize that the teachings herein can be applied in many different ways. Described implementations include those standards that support the following standards: Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard for ultra-wideband (UWB), IEEE 802.11 standard (including those identified as Wi-Fi® technology), Bluetooth® standard, code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), Global System for Mobile communications (GSM), GSM / General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband-CDMA (W-CDMA®), Evolution Data Optimized (EV-DO), 1xEV-DO, EV-DO Rev A, EV-DO Rev B, High Rate Packet Data (HRPD), High Speed ​​Packet Access (HSPA), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA), Evolved High Speed ​​Packet Access (HSPA+), Long Term EvolutionThe present invention may be implemented in any device, system, or network capable of transmitting and receiving radio frequency (RF) signals according to any communications standard, such as any of the LTE (LTE Evolution), Advanced Mobile Phone System (AMPS), or other known signals used to communicate within a wireless, cellular, or internet of things (IoT) network, such as a system utilizing 3G, 4G, 5G, 6G technologies, or further implementations thereof.

[0011] As used herein, an "RF signal" includes electromagnetic waves that transport information through space between a transmitter (or transmitting device) and a receiver (or receiving device). As used herein, a transmitter may transmit a single "RF signal" or multiple "RF signals" to a receiver. However, a receiver may receive multiple "RF signals" corresponding to each transmitted RF signal due to the propagation characteristics of RF signals through multiple channels or paths.

[0012] Additionally, unless otherwise specified, references to "reference signals," "positioning reference signals," "reference signals for positioning," and the like may be used to refer to signals used for positioning of user equipment (UE) in 5G New Radio (NR) networks. As described in more detail herein, such signals may include any of a variety of signal types, but may not necessarily be limited to Positioning Reference Signals (PRS) as defined in the relevant wireless standards.

[0013] Additionally, unless otherwise specified, the term "positioning" as used herein (including, for example, UWB-based positioning, cellular-based positioning, and hybrid cellular / UWB positioning) may include absolute location determination, relative location determination, ranging, or combinations thereof. Such positioning may include and / or be based on timing, angle, phase, or power measurements, or combinations thereof (which may include RF sensing measurements), for purposes of location or sensing services.

[0014] As previously mentioned, UWB-based positioning provides a high accuracy, low power positioning solution over other RF-based positioning techniques for wireless electronic devices. UWB-based positioning may be used in industrial applications by robots and / or other Internet of Things (IoT) devices in factory settings, indoor positioning of consumer electronics, etc. UWB-based positioning may be used in an ad-hoc manner as a standalone positioning technique between UWB positioning capable electronic devices (also referred to herein as "UWB devices"), but in some embodiments, UWB-based positioning may be used as one of many techniques for positioning electronic devices in a positioning system. FIG. 1 provides an example of such a positioning system.

[0015] 1 is a simplified diagram of a positioning system 100 in which a mobile device 105, a location server 160, and / or other components of the positioning system 100 can use techniques provided herein for a time alignment configuration for hybrid 5G and UWB positioning of a mobile device 105, according to one embodiment. Techniques described herein may be implemented by one or more components of the positioning system 100. The positioning system 100 can include a mobile device 105, one or more satellites 110 (also referred to as space vehicles (SVs)) for a Global Navigation Satellite System (GNSS), such as Global Positioning System (GPS), GLONASS, Galileo, or Beidou, base stations 120, access points (APs) 130, a location server 160, a network 170, and external clients 180. In general, the positioning system 100 can estimate the location of the mobile device 105 based on RF signals received by and / or sent from the mobile device 105, as well as known locations of other components (e.g., GNSS satellites 110, base stations 120, APs 130) that transmit and / or receive RF signals. Additional details regarding specific location estimation techniques are described below.

[0016] It should be noted that FIG. 1 provides only a generalized view of the various components, and that any or all of the components may be utilized where appropriate, and that each of the components may be replicated as necessary. In particular, while only one mobile device 105 is shown, it will be understood that many mobile devices (e.g., hundreds, thousands, millions, etc.) may utilize the positioning system 100. Similarly, the positioning system 100 may include more or fewer base stations 120 and / or APs 130 than those shown in FIG. 1. The illustrated connections connecting the various components in the positioning system 100 include data and signaling connections, which may include additional (intermediate) components, direct or indirect physical and / or wireless connections, and / or additional networks. Furthermore, components may be rearranged, combined, separated, substituted, and / or omitted depending on the desired functionality. In some embodiments, for example, the external client 180 may be directly connected to the location server 160. Those skilled in the art will recognize many modifications to the illustrated components.

[0017] Depending on the desired functionality, network 170 may include any of a variety of wireless and / or wireline networks. Network 170 may include any combination of, for example, public and / or private networks, local area networks and / or wide area networks, etc. Furthermore, network 170 may utilize one or more wired and / or wireless communication technologies. In some embodiments, network 170 may include, for example, a cellular or other mobile network, a wireless local area network (WLAN), a wireless wide-area network (WWAN), and / or the Internet. Examples of network 170 include LTE wireless networks, Fifth Generation (5G) wireless networks (also referred to as NR wireless networks or 5G NR wireless networks), Wi-Fi WLAN, and the Internet. LTE, 5G, and NR are wireless technologies defined or being defined by the 3rd Generation Partnership Project (3GPP). Network 170 may also include two or more networks and / or two or more types of networks. In a wireless cellular network (e.g., LTE or 5G), the mobile device 105 may be referred to as user equipment (UE).

[0018] The base stations 120 and access points (APs) 130 may be communicatively coupled to a network 170. In some embodiments, the base stations 120s may be owned, maintained, and / or operated by a cellular network provider and may utilize any of a variety of wireless technologies, as described herein below. Depending on the technology of the network 170, the base stations 120 may include a Node B, an evolved Node B (eNodeB or eNB), a base transceiver station (BTS), a radio base station (RBS), an NR NodeB (gNB), a Next Generation eNB (ng-eNB), etc. A base station 120 that is a gNB or ng-eNB may be part of a Next Generation Radio Access Network (NG-RAN), which may connect to a 5G Core Network (5GC) if the network 170 is a 5G network. The functions performed by base station 120 in previous generation networks (e.g., 3G and 4G) may be separated into different functional components (e.g., radio units (RUs), distributed units (DUs), and central units (CUs)) and layers (e.g., L1 / L2 / L3) in consideration of Open Radio Access Networks (O-RAN) and / or Virtualized Radio Access Networks (V-RAN or vRAN) in 5G or later networks, which may be executed on different devices in different locations connected, for example, via fronthaul, midhaul, and backhaul connections. As referred to herein, a "base station" (or ng-eNB, gNB, etc.) may include any or all of these functional components.The AP 130 may include, for example, a Wi-Fi AP or a Bluetooth AP or an AP with cellular capabilities (e.g., 4G LTE and / or 5G NR). Thus, the mobile device 105 can send and receive information to and from network connectivity devices, such as the location server 160, by accessing the network 170 via the base station 120 using the first communication link 133. Additionally or alternatively, the AP 130 may also be communicatively coupled to the network 170 such that the mobile device 105 can communicate with network connectivity devices, including the location server 160, and Internet connectivity devices using the second communication link 135 or via one or more other mobile devices 145.

[0019] The term "base station" as used herein may generally refer to a single physical transmission point or multiple co-located physical transmission points that may be located at a base station 120. A Transmission Reception Point (TRP) (also known as a transmit / receive point) corresponds to this type of transmission point, and the term "TRP" may be used interchangeably with the terms "gNB", "ng-eNB", and "base station" herein. In some cases, a base station 120 may include multiple TRPs, e.g., each TRP associated with a different antenna or different antenna array for the base station 120. As used herein, the transmission function of a TRP may be performed using a transmission point (TP) and / or the reception function of a TRP may be performed by a reception point (RP), which may be physically separate or distinct from the TP. However, a TRP may include both a TP and an RP. A physical transmission point may include an array of antennas of the base station 120 (e.g., as in the case of a Multiple Input-Multiple Output (MIMO) system and / or if the base station employs beamforming). The term "base station" may additionally refer to multiple non-co-located physical transmission points, which may be a Distributed Antenna System (DAS) (a network of spatially separated antennas connected to a common source via a transport medium) or a Remote Radio Head (RRH) (a remote base station connected to a serving base station).

[0020] The term "cell" as used herein may generally refer to a logical communication entity used for communication with base station 120 and may be associated with an identifier (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)) that distinguishes neighboring cells operating over the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., Machine-Type Communication (MTC), Narrowband Internet-of-Things (NB-IoT), Enhanced Mobile Broadband (eMBB), etc.) that may provide access to different types of devices. In some cases, the term "cell" may refer to a portion (e.g., a sector) of a geographic coverage area in which the logical entity operates.

[0021] The satellites 110 may be utilized for positioning of the mobile device 105 in one or more ways. For example, the satellites 110 (also referred to as space vehicles (SVs)) may be part of a GNSS, such as GPS, GLONASS, Galileo, or Beidou. Positioning using RF signals from GNSS satellites may include measuring multiple GNSS signals at a GNSS receiver of the mobile device 105 to perform code-based and / or carrier-based positioning, which may be highly accurate. Additionally or alternatively, the satellites 110 may be utilized for Non-Terrestrial Network (NTN)-based positioning, in which the satellites 110 may functionally operate as a TRP (or TP) of a network (e.g., an LTE and / or NR network) and may be communicatively coupled to the network 170. In particular, the reference signals (e.g., PRS) transmitted by the satellites 110 NTN-based positioning may be similar to the reference signals transmitted by the base stations 120 and may be coordinated by the location server 160. In some embodiments, the satellites 110 used for NTN-based positioning may be different from the satellites used for GNSS-based positioning.

[0022] Location server 160 may include servers and / or other computing devices configured to determine an estimated location of mobile device 105 and / or provide data (e.g., “assistance data”) to mobile device 105 to facilitate location measurement and / or location determination by mobile device 105. According to some embodiments, location server 160 may include a Home SUPL Location Platform (H-SLP), which may support a SUPL user plane (UP) location solution defined by the Open Mobile Alliance (OMA), and may support location services for mobile device 105 based on subscription information for mobile device 105 stored in location server 160. In some embodiments, location server 160 may include a Discovered SLP (D-SLP) or an Emergency SLP (E-SLP). The location server 160 may also include an Enhanced Serving Mobile Location Center (E-SMLC) that supports the location of the mobile device 105 using a control plane (CP) location solution for LTE radio access by the mobile device 105. The location server 160 may further include a Location Management Function (LMF) that supports the location of the mobile device 105 using a control plane (CP) location solution for NR or LTE radio access by the mobile device 105.

[0023] In a CP location solution, signaling for controlling and managing the location of the mobile device 105 may be exchanged between elements of the network 170 and to and from the mobile device 105 as signaling from the network 170's perspective using existing network interfaces and protocols. In a UP location solution, signaling for controlling and managing the location of the mobile device 105 may be exchanged between the location server 160 and the mobile device 105 as data from the network 170's perspective (e.g., data transported using Internet Protocol (IP) and / or Transmission Control Protocol (TCP)).

[0024] As mentioned previously (and described in more detail below), the estimated location of the mobile device 105 may be based on measurements of RF signals sent from and / or received by the mobile device 105. In particular, these measurements may provide information regarding the relative distance and / or angle of the mobile device 105 from one or more components in the positioning system 100 (e.g., GNSS satellites 110, APs 130, base stations 120). The estimated location of the mobile device 105 may be estimated geometrically (e.g., using multi-angulation and / or multi-lateration) based on the distance and / or angle measurements along with the known locations of the one or more components.

[0025] Terrestrial components such as APs 130 and base stations 120 may be fixed, although embodiments are not so limited. Mobile components may be used. For example, in some embodiments, the location of the mobile device 105 may be estimated based at least in part on measurements of RF signals 140 communicated between the mobile device 105 and one or more other mobile devices 145, which may be mobile or fixed. As shown, the other mobile devices may include, for example, a mobile phone 145-1, a vehicle 145-2, a static communication / positioning device 145-3, or other static and / or mobile devices capable of providing wireless signals used to position the mobile device 105, or combinations thereof. Wireless signals from the mobile device 145 used for positioning the mobile device 105 may include RF signals using, for example, Bluetooth (including Bluetooth Low Energy (BLE)), IEEE 802.11x (e.g., Wi-Fi), UWB, IEEE 802.15x, or combinations thereof. The mobile device 145 may additionally or alternatively use non-RF wireless signals for positioning of the mobile device 105, such as infrared signals or other optical techniques.

[0026] The mobile device 145 may include other mobile devices communicatively coupled to a cellular or other mobile network (e.g., network 170). When one or more other mobile devices 145 are used in determining the location of a particular mobile device 105, the mobile device 105 whose location is to be determined may be referred to as a "target mobile device" and each of the other mobile devices 145 used may be referred to as an "anchor mobile device." (In a cellular / mobile broadband network, the terms "anchor UE" and "target UE" may be used.) For purposes of determining the location of a target mobile device, the location of each of the one or more anchor mobile devices may be known and / or may be determined together with the target mobile device. Direct communication between the one or more other mobile devices 145 and the mobile device 105 may include sidelink and / or similar device-to-device (D2D) communication techniques. Sidelink, as defined by 3GPP, is a form of D2D communication under the cellular-based LTE and NR standards. UWB may be one such technology in which positioning of a target device (eg, mobile device 105) may be facilitated using measurements from one or more anchor devices (eg, mobile device 145).

[0027] According to some embodiments, one form of D2D communication used by the mobile device 105, such as when the mobile device 105 includes and / or is integrated into a vehicle, may include vehicle-to-everything (V2X) communication. V2X is a communication standard for vehicles and associated entities to exchange information about the traffic environment. V2X may include vehicle-to-vehicle (V2V) communication between V2X-enabled vehicles, vehicle-to-infrastructure (V2I) communication between vehicles and infrastructure-based devices (usually called roadside units (RSUs)), vehicle-to-person (V2P) communication between vehicles and nearby people (pedestrians, cyclists, and other road users), and the like. Additionally, V2X may use any of a variety of wireless RF communication technologies. Cellular V2X (CV2X) is a form of V2X that uses cellular-based communications, such as LTE (4G), NR (5G), and / or other cellular technologies in a direct communication mode defined by 3GPP. The mobile device 105 shown in FIG. 1 may correspond to a vehicle, an RSU, or a component or device on another V2X entity used to communicate V2X messages. Thus, in an embodiment in which V2X is used, the static communication / positioning device 145-3 (which may correspond to an RSU) and / or the vehicle 145-2 may communicate with the mobile device 105 and be used to determine the position of the mobile device 105 using techniques similar to those used by the base station 120 and / or the AP 130 (e.g., using multi-angulation and / or multi-lateration). It should be further noted that the mobile device 145 (which may include a V2X device), the base station 120, and / or the AP 130 may be used together (e.g., in a WWAN positioning solution) to determine the position of the mobile device 105 in accordance with some embodiments.

[0028] The estimated location of the mobile device 105 may be used in a variety of applications, such as to assist in direction finding or navigation for a user of the mobile device 105, or to assist another user (e.g., associated with the external client 180) in locating the mobile device 105. "Location" may also be referred to herein as a "location estimate," "estimated location," "location," "position," "position estimate," "position fix," "estimated position," "location fix," or "fix." The process of determining a location may be referred to as a "positioning," "position determination," "location determination," or the like. The location of the mobile device 105 may include the absolute location of the mobile device 105 (e.g., latitude and longitude and possibly altitude) or the relative location of the mobile device 105 (e.g., location expressed as a distance north-south, east-west, and possibly up-down from some other known fixed location (e.g., including the location of a base station 120 or AP 130) or some other location, such as the location of the mobile device 105 at some known prior time or the location of the mobile device 145 (e.g., another mobile device) at some known prior time). A location may be specified as a geodetic location including coordinates that may be absolute (e.g., latitude, longitude and optionally altitude), relative (e.g., relative to some known absolute location), or local (e.g., X, Y, and optionally Z coordinates according to a coordinate system defined for a local area such as a factory, warehouse, university campus, shopping mall, sports stadium, or convention center). A location may alternatively be a civic location, which may include one or more of a street address (e.g., including a country, state, county, city, road and / or street name or sign, and / or road number or street number), and / or a sign or name, such as a point, a building, a part of a building, a floor of a building, and / or a room within a building.The location may further include an uncertainty or error indication, such as the horizontal and possibly vertical distance over which the location is expected to be in error, or a representation of an area or volume (e.g., a circle or ellipse) within which the mobile device 105 is expected to be located with some level of confidence (e.g., 95% confidence).

[0029] The external client 180 may be a web server or remote application that may have some association with the mobile device 105 (e.g., that may be accessed by a user of the mobile device 105), or may be a server, application, or computer system that provides location services to some other user or users that may include obtaining and providing the location of the mobile device 105 (e.g., to enable services such as finding friends or relatives or locating children or pets). Additionally or alternatively, the external client 180 may obtain and provide the location of the mobile device 105 to an emergency services provider, a government agency, or the like.

[0030] FIG. 2A illustrates a scenario in which both UWB and cellular (5G NR) technologies may be used to position a target device 205, where the target device 205 may correspond to the mobile device 105 of FIG. 1. Generally, according to some embodiments, hybrid cellular / UWB positioning of a device (or simply "cellular / UWB positioning") may utilize both cellular and UWB positioning technologies to determine the location of a device capable of making positioning-related measurements in both cellular and UWB technologies. The use of both cellular and UWB technologies may utilize additional anchors (cellular anchors and / or UWB anchors) for positioning measurements, which may enable positioning of a device in situations where the use of a single technology does not, and / or with greater accuracy than the use of a single technology. Hybrid cellular / UWB positioning may also be referred to as (hybrid) "5G / UWB" or "NR / UWB" positioning when the cellular technology includes 5G NR.

[0031] In this scenario, the target device 205 may comprise a UE of a cellular network within the coverage area 210 of a base station 220, which may comprise the serving base station of the target device 205. Communication between the base station 220 and the target device 205 may occur over a network (Uu) interface 230, which may also be used to communicate DL and / or UL reference signals for the cellular aspects of hybrid cellular / UWB positioning. According to some embodiments, positioning of the target device 205 may be coordinated by the network via a location server (not shown), and related configuration and / or assistance data may be associated with the target device 205 by the base station 220 via the network interface 230.

[0032] In the UWB aspect of hybrid cellular / UWB positioning, the target device 205 may send and / or receive UWB RF signals from a UWB device 240 acting as a UWB anchor. The UWB RF signals may be coordinated using an out of band (OOB) interface 250, which may utilize, for example, Bluetooth, Wi-Fi, or similar wireless technology, which may have a corresponding wireless coverage area 245. According to some embodiments, the UWB aspect of hybrid cellular / UWB positioning may be coordinated by the target device 205 and / or the UWB device 240, or may be coordinated by a location server or other server (not shown). In some embodiments, configuration data and / or assistance data may be provided directly to the target device 205 and / or the UWB device 240 by the base station 220. In some embodiments, the configuration data and / or assistance data may be provided directly to the target device 205 by the base station 220 (e.g., via the network interface 230), and the target device 205 may relay the configuration data and / or assistance data to the UWB device 240 (e.g., via the OOB interface 250).

[0033] Although FIG. 2 shows a single base station 220 and a single UWB device 240, it should be noted that scenarios in which the hybrid cellular / UWB positioning of the target device 205 may involve one or more base stations and one or more UWB devices.

[0034] 2B is a simplified diagram illustrating how positioning of a target device 205 may be performed, according to some embodiments. Here, measurements using cellular technology may include round trip signal propagation delay (RTT) measurements performed between the target device 205 and each of the first base station 220-1 and the second base station 220-2 to determine the distance between the target device 205 and the base station 220. (These distances are represented by circle 260.) In addition, as shown, measurements and UWB may include RTT measurements (also called two-way ranging (TWR) in UWB) performed to determine the distance between the target device 205 and one or more UWB anchors, such as the UWB device 240. (The distance between the target device 205 and the UWB device 240 is represented by circle 270.) Using multilateration, the location of the target device 205 may be determined as the location where the distance circles (circles 260 and 270) intersect. Because the distance may have some uncertainty, the resulting location of the target device 205 may also have some uncertainty.

[0035] 3A is a flow diagram illustrating the roles that different devices may assume with respect to a UWB ranging session (or simply "UWB session"). Here, each UWB device may be referred to as an enhanced ranging device (ERDEV). The ERDEV may be referred to by different terms (e.g., initiator / responder or controller / controller) at different layers of the network stack. The terms initiator and responder (described below) will be used at lower layers (e.g., UWB physical (PHY) layer and media access control (MAC) layer), and the terms controller and controller (also described below) may be used at higher layers (e.g., application layer of the ERDEV). Here, any ERDEV may correspond to target device 205 or UWB device 240 of FIG. 2, or mobile device 105 of FIG. 1.

[0036] As shown, for a pair of ERDEVs communicating with each other, the controller 310 is the ERDEV that sends control information 325 to a receiving ERDEV designated as the controllee 320. The control information 325 may include parameters for the UWB ranging session, such as timing, channel, etc. Although not shown, the controllee 320 may send acknowledgments to the control information 325, negotiate changes to the parameters, etc.

[0037] The exchange between the controller 310 and the controlley 320, including the transmission of the control information 325 and subsequent associated exchanges between the controller 310 and the controlley 320 regarding the control information, may occur out-of-band (OOB) using different wireless communication technologies (e.g., Bluetooth or Wi-Fi) prior to the ranging phase. In other words, a UWB session may be associated with a control phase and a ranging phase, where the control phase (which may occur over an OOB link) includes a preliminary exchange between the controller 310 and the controlley 320 of parameter values ​​for the ranging phase, and the subsequent ranging phase includes the portion of the UWB session where the devices exchange messages within the UWB band for ranging measurements. (Note, however, that some control information may be exchanged within the UWB band (e.g., the "ranging control phase" that occurs in the first slot of a UWB round. Thus, some aspects of the control phase may be considered to occur in-band after the preliminary OOB exchanges between the controller 310 and the controlley 320.)

[0038] A UWB session may occur later according to parameters provided in the control information. In the ranging phase of the UWB session, one ERDEV may play the role of initiator 330 and the other ERDEV may play the role of responder 340. As shown in FIG. 3A, the initiator 330 may start UWB ranging by sending a ranging start message 345 to the responder 340, which may respond with a ranging response message 350, and timing measurements may be made from these messages (by the device receiving the message) to perform two-way ranging (TWR). Depending on the parameters of the control information 325, additional exchanges may take place in the ranging phase between the initiator 330 and the responder 340 to enable additional ranging measurements.

[0039] The roles of initiator 330 and responder 340 may be indicated in the control information 325. Additionally, as shown in FIG. 3A, the controller 310 in the control phase may be the initiator 330 in the ranging phase of the UWB session. Alternatively, as shown in FIG. 3B, the controller 310 in the control phase may be the responder 340 in the ranging phase. The determination of which device is the initiator 330 and which is the responder 340 may depend on parameters set forth in the control information 325, in which case the controllee 320 will be either the responder 340 or the initiator 330, correspondingly. According to some embodiments, a controller / initiator may perform ranging with multiple controllees / responders.

[0040] Embodiments herein can help ensure that UWB and cellular measurements hybrid cellular / UWB positioning are aligned in the time domain to accurately reflect the location (e.g., at a given time) of a target UE. To do this, embodiments provide for measurement coordination between cellular reference signals and UWB positioning sessions. Figure 4 shows how this coordination can be performed according to some embodiments.

[0041] FIG. 4 is a flow diagram illustrating how a location server (e.g., an LMF in a 5G network) may be used to coordinate hybrid cellular / UWB positioning of a UE according to some embodiments. Here, a first UE 405 may communicate with a location server 410 to coordinate a UWB positioning session with one or more UWB devices 415 capable of UWB positioning. In some embodiments, the UWB device(s) 415 may be capable of 5G wireless communication and / or positioning and thus may be a UE(s) in a 5G wireless network. In some embodiments, the UWB device(s) 415 may not be capable of 5G wireless communication and / or positioning. Communication between the location server 410 and the first UE 405 may be via an associated communication protocol of the 5G wireless network, such as the LTE positioning protocol (LPP). The first UE 405 may include a target UE for which a position determination is desired.

[0042] As shown, the process may begin with an exchange of the first UE's UWB capabilities. This exchange may include the location server 410 requesting UWB capabilities, as indicated by arrow 420, to which the first UE 405 may respond by providing its UWB capabilities, as indicated by arrow 425. According to some embodiments, the first UE 405 (acting as a controller) may inform the location server 410 (acting as a controller) of information to negotiate UWB configuration parameters. This information may include conventional UWB configuration parameters as provided in the relevant UWB standard. Additionally or alternatively, the parameters may include quality of service (QOS) related parameters, such as pulse shape selection, desired accuracy (either by Tx or Rx), type of positioning algorithm to be utilized (allowing the location server to measure the latency involved), or any combination thereof.

[0043] Based on these UWB capabilities, the location server 410 can then provide UWB assistance data, as indicated by arrow 430. The UWB assistance data may also be based on prior knowledge of the location of the first UE 405 and the presence of nearby UWB device(s) 415 that have UWB capabilities.

[0044] The assistance data may include relevant parameters for conducting a UWB session between the UE 405 and the UWB device(s) 415. This may include the ranging method (e.g., one-way ranging (OWR), single-sided TWR (SS-TWR), double-sided TWR (DS-TWR)), number of controllers, multi-node mode (e.g., one-to-one or one-to-many), ranging message formats supported (SP0-SP3), time of flight (ToF) and / or angle of arrival (AoA) reporting, clock draft (which may include a numerical value, a range, or a threshold, such as whether the clock drift is within 25 ppm), scrambled timestamp sequence (STS) configuration (e.g., static or dynamic), maximum number of retries allowed, block stride (e.g., whether UWB blocks can be skipped), session start time until the first UWB packet is sent, block / round / slot duration, PRF mode (e.g., B PRF or H PRF). The assistance data may include a PRF, a channel number, a key rotation, or a CAP size range (e.g., minimum and maximum range values ​​for CAP size), or a combination thereof. Additionally or alternatively, the assistance data may indicate which UE should be the initiator and which UE should be the responder for each UWB session between the first UE 405 and the UWB device(s) 415.

[0045] The exchanges indicated by arrows 420 and 425 may be similar to the OOB exchanges made by a controller and a controllee in a control phase of a UWB session (e.g., as shown in Figures 3A and 3B), where the OOB technology used includes a 5G communication link (e.g., using LPP messages), the location server 410 includes the controller, and the first UE 405 includes the controllee. The UWB assistance data (provided at arrow 430) may include control information for the UWB session.

[0046] Optionally (as indicated by the dotted arrow 435), the location server 410 may request UWB location information from the first UE 405. The requested UWB location information may include UWB measurements performed by the first UE 405 and / or the UWB device(s) 415. According to some embodiments, the request may include new parameters for optimizing UWB and 5G measurements. This action may be performed by the location server 410 for UE-assisted positioning where the location server 410 determines the location of the first UE 405 and / or where the location of the first UE 405 is desired by the network (e.g., in response to a positioning request made by a positioning function in the mobile / cellular network or an external client). Alternatively, the location server 410 may not request UWB location information (e.g., in the case of UE-based positioning).

[0047] At block 440, the first UE 405 and the UWB device(s) 415 engage in one or more UWB sessions to perform UWB measurements. The UWB session(s) may be conducted according to parameters provided by the location server 410 in the assistance data.

[0048] The remaining actions in the process illustrated in FIG. 4 may depend on whether the position is determined by the first UE 405 (e.g., UE-based positioning) or whether the position is determined by the location server 410 (e.g., UE-assisted positioning). In the case of UE-based positioning, the UE may perform a positioning calculation, as illustrated in block 445. Alternatively, in the case of UE-assisted positioning (e.g., the location server 410 sends a request for UWB location information, as illustrated in arrow 435), the UE may provide the requested UWB location information to the location server, as illustrated in arrow 450. Upon receiving the UWB location information, the location server 410 may calculate the position of the first UE 405, as illustrated in block 455. To enable position determination, the UWB location information may include measurement information of UWB measurements performed during the UWB procedure of block 440. This information may include the measurement, the UE-UWB-ID, and a timestamp. It may also include location information of the UWB device(s) 415, if known. This location information may be provided to the first UE 405 by the UWB device(s) 415 during the UWB procedure of block 440. In the case of a UE-assisted mode, the location information may include a position estimate of the UE calculated by the UE.

[0049] Because the location server may be used to centrally coordinate UWB and cellular measurements for hybrid cellular / UWB positioning, the location server may implement optimizations to help ensure accurate positioning. As mentioned, this may include ensuring that cellular and UWB measurements are aligned in the time domain (e.g., occur within a threshold amount of time from each other). This may help to minimize changes in the wireless channel when cellular and UWB measurements are performed. Other optimizations may include ensuring that UWB sessions occurring during the same time do so using different frequencies or channels.

[0050] The location server may include configuration information in the assistance data (or any other data constituting the UWB and / or cellular positioning session in which UWB and cellular measurements are made) to help implement such optimization. This optimized configuration information may include, for example, a measurement time window in which both UWB and cellular measurements are to be made. Upon receiving this configuration information, the UE is expected to perform measurements in UWB and cellular within the proposed measurement time window. This may allow for time alignment to avoid errors due to UE mobility. This may also drive the start and duration of the UWB ranging session. The optimized configuration information may further include adjusting the cellular frequency (e.g., 5G band PRS) based on information regarding the channel frequency to be used for UWB and / or knowledge of the UWB band used. This may be done to help minimize any interference between cellular signal(s) (e.g., PRS) and UWB occurring in overlapping frequency bands and / or to increase diversity.

[0051] 5 is a timing diagram illustrating an approach to time domain alignment according to some embodiments. The diagram shows the relative timing for cellular (5G) measurements (using measurements of 5G PRS) and UWB measurements.

[0052] The PRS may be used for positioning in NR (and / or other cellular) wireless networks and may be transmitted by wireless network nodes, such as base stations (e.g., TRPs) and network-attached UEs communicatively coupled to the NR wireless network. Depending on the type of positioning performed, the PRS may be used for positioning measurements, such as time difference of arrival (TDOA), angle of departure (AoD), round-trip signal propagation delay (RTT), or combinations thereof. A "PRS instance" or "PRS opportunity" is one instance of a periodically repeating time window (e.g., a group of one or more contiguous slots in Orthogonal Frequency Division Multiplexing (OFDM) used in NR wireless networks) during which the PRS is expected to be transmitted. A PRS opportunity may also be referred to as a "PRS positioning occasion", "PRS positioning instance", "positioning occasion", "positioning instance", or simply an "opportunity" or "instance". Since the PRS may be broadcast, the first PRS 510 and the second PRS 520 may be received by either or both of the initiator and responder devices in a UWB positioning session (e.g., depending on their capabilities). The first PRS 510 and the second PRS 520 may include two instances of a PRS sequence (which may include more instances) transmitted in a periodicity 530. The default value of the periodicity 530 for the PRS is 160 ms, but this is configurable (e.g., by a location server) and may vary depending on the desired functionality.

[0053] Timing in a UWB session may occur over a time period divided into subparts according to a hierarchical structure. Similar to the TDMA method, a UWB session defines the timing during which ranging may occur. This timing includes one or more consecutive ranging blocks 540, which may have a configurable duration (e.g., 200 ms). Each ranging block 540 may be divided into one or more consecutive rounds 550 (e.g., N rounds), the number and length of which are configurable. The rounds 550 are further divided into different slots 560, also with a configurable number and length. According to some embodiments, a single round in each ranging block 540 may be used for UWB positioning to help reduce RF collisions.

[0054] Since the location server is aware of the parameters of the first and second PRSs 510, 520 (e.g., periodicity 530, duration (e.g., 4 ms), frequency, etc.), it can help ensure that the UWB ranging block 540 of a UWB positioning session for hybrid NR / UWB positioning is aligned with the first and second PRSs 510, 520 in an optimal manner by providing assistance data to configure the UWB device to help ensure this alignment. In particular, the location server (acting as a controller) can provide assistance data to a controlley UE (e.g., the first UE 405 of FIG. 4) that configures the controlley UE to specify the start of the ranging block 540, which round 550 should be used within the ranging block for UWB positioning, which number of slots should be used within the ranging round, or a combination thereof, based on the capabilities of the controlley UE.

[0055] FIG. 6A illustrates an example of how a location server may configure a UWB session to optimize hybrid NR / UWB positioning. Here, the location server provides assistance data to configure the controlley UE to use a selected round 610 of the ranging block 620 to be used for UWB positioning. The selected round 610 may be identified in the assistance data using its corresponding round index (e.g., round #2). To help ensure time domain alignment with NR positioning, a round may be selected for UWB positioning based on how close it is in time to the PRS. In FIG. 6A, the selected round 610 is the round in the ranging block 620 that is closest in time to the PRS 630 without overlapping in time with the PRS 630 (thereby avoiding potential interference). In general, a round may be selected based on whether it occurs within a threshold amount of time from the PRS. This time threshold may be based on the QoS capabilities of the controlley UE, the mobility of the controlley UE, the QoS requirements of the positioning session, or other such factors, or a combination thereof. The selected round 610 may occur after the closest PRS 630, as shown in FIG. 6A, or may occur before the closest PRS 630, as shown in FIG. 6B.

[0056] 7 illustrates an example of coordination of NR and UWB positioning sessions for hybrid NR / UWB positioning, where three UWB positioning sessions are conducted between three devices capable of both NR and UWB positioning (herein "NR / UWB devices"). The UWB sessions occur between a different pair of NR / UWB devices for each of session 1, session 2, and session 3, as shown in configuration 700. (In configuration 700, the shaded NR / UWB devices may include initiators for the UWB sessions. In this example, the same NR / UWB device is the initiator for both session 1 and session 2.)

[0057] In this example, PRS 710 may be broadcast (e.g., by a base station or other wireless network node of a 5G network) and received by all three NR / UWB devices. To avoid interference between PRS 710 and the UWB ranging sessions, the location server may configure the NR / UWB devices such that the UWB sessions occur after PRS 710, as shown. In this example, the ranging blocks for each of Session 1, Session 2, and Session 3 start at the same time, although in alternative embodiments, the sessions may occur at different times. To avoid RF collisions, the different sessions use different rounds for UWB positioning. (As indicated by the shading, Session 1 uses Round #1, Session 2 uses Round #2, and Session 3 uses Round #3.) 5G NR positioning may utilize multiple PRSs, and UWB ranging sessions may utilize multiple ranging blocks (which may use the same respective rounds, as shown in FIG. 7).

[0058] 7 shows just one example configuration. The time alignment between different UWB sessions and / or between UWB sessions and PRSs may vary depending on the desired functionality. Additional examples are provided in the following figures.

[0059] FIG. 8 illustrates another example of cooperation of NR and UWB positioning sessions for hybrid NR / UWB positioning. Here again, three UWB positioning sessions are performed (e.g., between three NR / UWB devices). However, in this example, the ranging blocks are offset in time from each other, and the same round (round #1) is selected in each ranging block for UWB positioning. This example does not show any overlap between ranging blocks of different sessions, but alternative embodiments may have overlap. Additionally or alternatively, different sessions may use different respective rounds for UWB positioning (e.g., rather than using the same respective round). The location server may configure the NR / UWB device with non-overlapping ranging blocks (e.g., rather than overlapping ranging blocks as shown in FIG. 7) to accommodate NR / UWB device capabilities, if the NR / UWB device may not be able to participate in multiple UWB positioning sessions at once.

[0060] 9 illustrates another example of NR and UWB positioning session coordination for hybrid NR / UWB positioning. In this example, UWB sessions (Session 1 and Session 2) are performed, with the ranging block for Session 1 configured to occur before PRS 910 and the ranging block for Session 2 configured to occur after PRS 910. As can be seen, this can allow UWB positioning to be more aligned with PRS 910 if both ranging blocks occur after (or before) PRS 910. Additionally, as shown, the rounds within the ranging block can be selected to align UWB positioning even more with PRS 910. Although, alternative embodiments may use rounds different from those illustrated.

[0061] 10 is a diagram showing yet another example of cooperation of NR and UWB positioning sessions for hybrid NR / UWB positioning. This example combines simultaneous (or overlapping) ranging blocks of different sessions (as shown in FIG. 7) with selecting rounds that are time-aligned close to the PRS 1010 (as shown in FIG. 9). In this case, the rounds in the ranging blocks of different sessions are selected to be close to the PRS 1010. However, to avoid interference with the PRS 1010, the rounds in the ranging blocks that overlap with the PRS 1010 (round #2) are not selected for UWB positioning.

[0062] As would be apparent to one skilled in the art, different combinations of the principles illustrated in Figures 7-10 may be applied in different hybrid NR / UWB positioning configurations depending on the desired functionality. That is, the ranging blocks and rounds selected for UWB positioning aligned with the PRS in any of a variety of ways to help optimize time alignment and reduce interference. Furthermore, depending on device capabilities, the location server may configure multiple UWB positioning sessions in parallel using different channels. For example, two pairs of devices may perform UWB positioning simultaneously (even using the same or overlapping rounds) without interference on different channels if different devices are used. (A single device may not be able to operate on two channels simultaneously given hardware limitations.) For devices involved in multiple positioning sessions simultaneously on different channels / frequencies, the location server may consider the time it may take to retune RF components from one frequency / channel to another when determining the hybrid NR / UWB positioning configuration. Additionally, alternative embodiments may use forms of hybrid cellular / UWB positioning that include additional and / or alternative cellular technologies (e.g., in addition to or as an alternative to 5G NR).

[0063] As mentioned previously, a UWB session may include multiple ranging blocks, and multiple ranging blocks may occur consecutively over a period of time. For a given UWB session, UWB measurements are made in the same round of each ranging block (e.g., the same round index is used for each ranging block) unless a new round index is specified (e.g., in new assistance data) or hopping is selected (in which case different rounds are used for different ranging blocks). In some implementations, the periodicity between PRSs (e.g., periodicity 530 in FIG. 5) may not be a multiple of the length of a ranging block. Thus, a given round in a first ranging block that does not overlap (and potentially collide) with a PRS may collide in a subsequent ranging block / PRS. Thus, a hopping mode for round usage in UWB positioning (also referred to herein as "UWB round hopping") may be used, where different rounds (e.g., rounds with different round indexes) are used in consecutive ranging blocks of a UWB session.

[0064] According to the relevant UWB standard, UWB round hopping utilizes a random sequence generator using the Advanced Encryption Standard (AES) that generates a randomized round index for every round in a given block. The sequence generator uses the session ID of the UWB session, which can help ensure that a secure pattern is generated. The use of a random sequence generator can help reduce collisions. However, since the hopping is random, random collisions can still occur.

[0065] While some embodiments may utilize such random hopping, some embodiments may utilize a designated hopping pattern that may be determined by the location server and provided to the cellular / UWB device via the assistance data. That is, since the location server may know the PRS transmission timing, the location server may determine (e.g., prior to UWB positioning in a hybrid cellular / UWB positioning session) whether a collision may occur between the PRS transmission and the round used for UWB positioning, for example, if a static round index is used for the UWB positioning session. To help avoid collisions (and avoid any possible collisions that may occur if random hopping is utilized), the location server may determine a hopping pattern that avoids collisions with the PRS transmission (and other UWB mono sessions that the location server may be aware of) and include the hopping pattern in the assistance data to the cellular / UWB device(s) of the affected UWB positioning session(s). According to some embodiments, this predetermined hopping pattern may be multicast by the location server to multiple cellular / UWB devices (e.g., over a secure link as part of UWB assistance data), which may be wirelessly relayed to the multiple cellular / UWB devices, e.g., via one or more base stations of the cellular network.

[0066] Although embodiments described herein illustrate providing UWB assistance data for each UWB positioning session, embodiments are not so limited. Embodiments may include, for example, providing UWB assistance data applicable to more than one UWB positioning session (e.g., positioning sessions occurring in succession). Thus, according to some embodiments, parameters and / or other information provided to a UWB device for use in a UWB positioning session may apply to a set of one or more UWB positioning sessions.

[0067] Figure 11A is a flow diagram of a method 1100-A for cellular / UWB positioning, according to one embodiment. The means for performing the functions illustrated in one or more of the blocks illustrated in Figure 11A may be performed by hardware and / or software components of a server (e.g., a computer server). Exemplary components of a computer system that may include a server are illustrated in Figure 14, which is described in more detail below.

[0068] In block 1110, the function includes sending a request from the server to the first wireless device, the first wireless device capable of transmitting both cellular and UWB wireless signals, for capability information including information regarding the capability of the first wireless device to perform UWB positioning. According to some embodiments, the exchange between the server and the first wireless device may be similar to the exchange between a controller and a controllee in a control phase of a UWB positioning session. Thus, the server may act as a controller and the first wireless device may act as a controllee. The communication between the server and the first wireless device may be relayed by one or more additional devices (e.g., a base station of a cellular wireless network, such as an LTE or NR network). Means for performing the functions in block 1110 may include a bus 1405, a processor(s) 1410, a memory 1435, a communications subsystem 1430 (e.g., including an optional wireless communications interface 1433 and / or an optional UWB transceiver 1434), and / or other components of computer system 1400, as shown in FIG. 14 and described below.

[0069] The function at block 1120 includes receiving a response from the first wireless device at the server including capability information. The capability information (including information regarding the capability of the first wireless device to perform UWB positioning) may include capability information including channel capabilities, measurement capabilities (type of measurement, accuracy / precision, etc.), timing capabilities (e.g., availability of UWB positioning), message format capabilities, etc. Also, as mentioned, the device may also provide QoS related parameters for the s UWB positioning session. Thus, according to some embodiments of method 1100-A, the response received at block 1120 may further include QoS parameters including information indicating pulse shape, desired accuracy, or type of positioning algorithm for the first set of one or more UWB positioning sessions, or a combination thereof. Means for performing the functions in block 1120 may include a bus 1405, a processor(s) 1410, a memory 1435, a communications subsystem 1430 (e.g., including an optional wireless communications interface 1433 and / or an optional UWB transceiver 1434), and / or other components of computer system 1400, as shown in FIG. 14 and described below.

[0070] The functions in block 1130 include determining first UWB assistance data for the first wireless device, the first UWB assistance data including one or more parameters for a first set of one or more UWB positioning sessions between the first wireless device and the second wireless device, based at least in part on (i) the capability information and (ii) information regarding one or more positioning signals transmitted in the cellular wireless network. As mentioned, the server may include a location server (e.g., an LMF server) that may have knowledge of where a PRS is transmitted in the cellular wireless system and will be used by one or more devices participating in the first set of one or more UWB positioning sessions. Thus, the server may determine the first UWB assistance data that time-aligns the UWB positioning measurements with the PRS (e.g., in the manner shown in the previously described embodiment). The one or more parameters of the first set of one or more UWB positioning sessions may include configurations that convey this time domain alignment. According to some embodiments, the one or more parameters for the first set of one or more UWB positioning sessions include a starting time of a ranging block, a round of a ranging block to use, a number of slots to use within a round of a ranging block, or a frequency channel to use, or a combination thereof. Additionally or alternatively, as previously described, the server may determine a hopping pattern to use during the set of one or more UWB positioning sessions to avoid interference with the PRS. Thus, some embodiments of method 1100-A may further include determining a hopping pattern for round use in the first set of one or more UWB positioning sessions based on information regarding one or more positioning signals transmitted in the cellular wireless network, and the one or more parameters for the first set of one or more UWB positioning sessions include the determined hopping pattern.Means for performing the functions in block 1130 may include a bus 1405, a processor(s) 1410, a memory 1435, a communication subsystem 1430, and / or other components of the computer system 1400, as shown in FIG. 14 and described below.

[0071] At block 1140, the method 1100-A includes sending the first UWB assistance data from the server to the first wireless device. As mentioned, according to some embodiments, the cellular wireless network may include an NR wireless network and the server may include an LMF of the cellular wireless network. In such embodiments, the request, response, or the first UWB assistance data, or a combination thereof, may be communicated via LPP. Additionally or alternatively, the one or more positioning signals may include one or more positioning reference signal (PRS) instances. However, other types of signals used for positioning, such as a tracking reference signal (TRS), a Channel-State Information Reference Signal (CSI-RS), etc., may be used.

[0072] The means for performing the functions in block 1140 may include bus 1405, processor(s) 1410, memory 1435, communication subsystem 1430 (e.g., including optional wireless communication interface 1433 and / or optional UWB transceiver 1434), and / or other components of computer system 1400, as shown in FIG. 14 and described below. [We should have another flow diagram that captures the operations / functions from the UE's perspective (e.g., receiving a request for capability information from a location server, providing capability information to a server, receiving assistance data from a server including UWB ranging configuration information, performing UWB ranging based on the configuration information, etc.).]

[0073] As mentioned in the previously described embodiments, configuring the first wireless device for cellular / UWB positioning may implement one or more additional features depending on the desired functionality. As shown in Figures 6A and 6B, a round of UWB ranging blocks closest to the PRS may be selected to help ensure time alignment. Thus, according to some embodiments of method 1100-A, one or more parameters for a first set of one or more UWB positioning sessions may specify using one selected round from multiple rounds of ranging blocks. For a particular positioning signal of one or more positioning signals, the selected round may be closest in time to the particular positioning signal of the multiple rounds, and the selected round may not overlap in time with the particular positioning signal.

[0074] As mentioned in FIGS. 7-10, the location server may configure the multiple UWB sessions to be optimally time-aligned with the PRS according to some embodiments. Accordingly, some embodiments of method 1100-A may further include sending second UWB assistance data including one or more parameters for a second set of one or more UWB positioning sessions, where the second UWB assistance data may be sent from the server to the first wireless device, the second wireless device, or a third wireless device, or a combination thereof. In such an embodiment, the one or more parameters for the first set of one or more UWB positioning sessions may specify using a first round of a first ranging block having a first round index, and the one or more parameters for the second set of one or more UWB positioning sessions may specify using a second round of a second ranging block having a second round index different from the first round index, where the first ranging block and the second ranging block overlap in time.

[0075] As shown in Figures 7 and 10, overlapping ranging blocks may use different rounds to optimize time alignment with the PRS. Thus, according to some embodiments of method 1100-A, for a particular positioning signal of one or more positioning signals that is closest in time to a first round, the first round may occur after the particular positioning signal, and the second round may occur after the first round. According to some embodiments, for a particular positioning signal of one or more positioning signals that is closest in time to a first round, the first and second ranging blocks may overlap in time with the particular positioning signal, and the first round may occur before the particular positioning signal, and the second round may occur after the particular positioning signal.

[0076] As shown in Figures 8 and 9, separate ranging blocks may be used for time alignment. According to some embodiments of the method 1100-A, the one or more parameters for a first set of one or more UWB positioning sessions specify using a first round of a first ranging block having a first round index, and the one or more parameters for a second set of one or more UWB positioning sessions specify using a second round of a second ranging block having a second round index, where the first ranging block and the second ranging block do not overlap in time. In such an embodiment, for a particular positioning signal of the one or more positioning signals that is closest in time to the first ranging block, the first ranging block may occur after the particular positioning signal, the second ranging block may occur after the first round, and the second round index may be the same as the first round index. According to some embodiments, for a particular positioning signal of one or more positioning signals that is closest in time to a first ranging block, the first ranging block may occur before the particular positioning signal and the second ranging block may occur after the particular positioning signal.

[0077] Figure 11B is a flow diagram of a method 1100-B for cellular / UWB positioning, according to one embodiment. The means for performing the functions illustrated in one or more of the blocks illustrated in Figure 11B may be performed by hardware and / or software components of a UWB device. Exemplary components of a UWB device are illustrated in Figures 12 and 13, which are described in more detail below.

[0078] In block 1150, the function includes receiving a request for capability information from a server at a first wireless device capable of transmitting both cellular and UWB wireless signals. As mentioned, according to some embodiments, the exchange between the server and the first wireless device may be similar to the exchange between a controller and a controlee in a control phase of a UWB positioning session. Thus, the server may act as a controller and the first wireless device may act as a controlee. The communication between the server and the first wireless device may be relayed by one or more additional devices (e.g., a base station of a cellular wireless network, such as, for example, an LTE or NR network). Means for performing the function in block 1150 may include a bus 1205, a processor(s) 1210, a memory 1260, a wireless communication interface 1230 (including an optional UWB transceiver 1235), and / or other components of the mobile UWB device 1200, as shown in FIG. 12 and described below. The means for performing the functions in block 1150 may alternatively include a bus 1305, a processor(s) 1310, a memory 1360, a wireless communication interface 1330 (including an optional UWB transceiver 1335), and / or other components of the stationary UWB device 1300, as shown in FIG. 13 and described below.

[0079] The function at block 1160 includes sending a response from the first wireless device to the server including capability information including information regarding the capability of the first wireless device to perform UWB positioning. The capability information (including information regarding the capability of the first wireless device to perform UWB positioning) may include capability information including channel capabilities, measurement capabilities (type of measurement, precision / accuracy, etc.), timing capabilities (e.g., availability of UWB positioning), message format capabilities, etc. Also, as mentioned, the device may also provide QoS related parameters for the s UWB positioning session. Thus, according to some embodiments of method 1200-B, the response received at block 1160 may further include QoS parameters including information indicating pulse shape, desired accuracy, or type of positioning algorithm for the first set of one or more UWB positioning sessions, or a combination thereof. Means for performing the functions in block 1160 may include bus 1205, processor(s) 1210, memory 1260, wireless communication interface 1230 (including optional UWB transceiver 1235), and / or other components of mobile UWB device 1200, as shown in Figure 12 and described below.

[0080] The functions in block 1170 may include receiving first UWB assistance data from a server at the first wireless device, the first UWB assistance data including one or more parameters for a first set of one or more UWB positioning sessions between the first wireless device and the second wireless device. As mentioned, the server may include a location server (e.g., an LMF server) that may have knowledge of where the PRS is transmitted in the cellular wireless system and used by one or more devices participating in the first set of one or more UWB positioning sessions. Thus, the server may determine the first UWB assistance data that time-aligns the UWB positioning measurements with the PRS (e.g., in the manner shown in the previously described embodiment). The one or more parameters of the first set of one or more UWB positioning sessions may include configurations that convey this time domain alignment. According to some embodiments, the one or more parameters for the first set of one or more UWB positioning sessions include a starting time of a ranging block, a round of ranging blocks to use, a number of slots to use within a round of ranging blocks, or a frequency channel to use, or a combination thereof. Additionally or alternatively, as previously described, the server may determine a hopping pattern to use in the set of one or more UWB positioning sessions to avoid interference with the PRS. Thus, in some embodiments of method 1100-B, the one or more parameters for the first set of one or more UWB positioning sessions include the determined hopping pattern. Means for performing the functions in block 1170 may include bus 1205, processor(s) 1210, memory 1260, wireless communication interface 1230 (including optional UWB transceiver 1235), and / or other components of mobile UWB device 1200, as shown in FIG. 12 and described below.The means for performing the functions in block 1170 may alternatively include a bus 1305, a processor(s) 1310, a memory 1360, a wireless communication interface 1330 (including an optional UWB transceiver 1335), and / or other components of the stationary UWB device 1300, as shown in FIG. 13 and described below.

As mentioned, according to some embodiments, the cellular wireless network may include an NR wireless network and the server may include an LMF of the cellular wireless network. In such embodiments, the request, response, or first UWB assistance data, or a combination thereof, may be communicated via LPP. Additionally or alternatively, the one or more positioning signals may include one or more positioning reference signal (PRS) instances. Although, other types of signals used for positioning, such as tracking reference signals (TRS), channel state information reference signals (CSI-RS), etc., may be used.
