[0001] This application claims the benefit of U.S. Application No. 18 / 609,864, filed March 19, 2024, entitled “COEXISTENCE OF UWB AND OTHERTRANSMISSIONS”, which has been assigned to the assignee of this application, and the entire contents of that U.S. application are incorporated herein by reference for all purposes. Background Technology

[0002] Wireless communication systems have gone through several generations of development, including first-generation analog wireless telephone service (1G), second-generation (2G) digital wireless telephone service (including transitional 2.5G and 2.75G networks), third-generation (3G) high-speed data wireless service with internet capabilities, and fourth-generation (4G) services (e.g., LTE or WiMax). ® This includes fifth-generation (5G) services (e.g., 5G New Radio (NR)) and sixth-generation (6G) services currently under development. There are many different types of wireless communication systems in use today, including cellular and Personal Communication Services (PCS) systems. Known examples of cellular systems include Advanced Cellular System (AMPS) based on analog cellular networks, and digital cellular systems based on Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Time Division Multiple Access (TDMA), and GSM TDMA variants.

[0003] The fifth-generation (5G) mobile standard demands higher data transmission speeds, a greater number of connections, better coverage, and other improvements. According to the Next Generation Mobile Networks Alliance (NGC), the 5G standard is designed to provide tens of megabits per second (Mbps) of data to each of tens of thousands of users, or 1 gigabit per second (Gbps) 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.

[0004] The sixth-generation (6G) network is expected to be significantly faster and more versatile than previous generations, and will be able to support new applications. 6G networks are expected to operate in frequency bands used by other applications, such as ultra-wideband (UWB) applications for communication in the 3.1 GHz to 10.6 GHz spectrum. For example, comprehensive specifications for UWB applications can be found in, for example, IEEE standards. 802.15.4z-2020 discusses the enhanced ultra-wideband (UWB) physical layer (PHY) and associated ranging techniques.

[0030] This document discusses techniques for facilitating UWB (Ultra-Wideband) signal transmission as part of a UWB session between User Equipments (UEs) while (e.g., partially or completely) avoiding interference from one or more radio signal transmissions, such as those at the same frequency as the UWB signal transmission. For example, a radio signaling device (e.g., a network entity, another UE (e.g., a UWB device)) may generate a first signal transmission schedule, and the UE may acquire (e.g., receive and / or learn) the first signal transmission schedule and determine a second signal transmission schedule (i.e., a UWB signal transmission schedule) to avoid overlap with the first signal transmission schedule (e.g., in time and frequency, directly or due to harmonics). The radio signaling device may determine the first signal transmission schedule based on receiving UWB scheduling information (e.g., the second signal transmission schedule) from the UE. As another example, the radio signaling device may receive UWB scheduling information from one or more UEs for one or more second signal transmission schedules, determine one or more first signal transmission schedules to avoid overlap with the second signal transmission schedules, and transmit the first signal transmission schedule to the UE. A UE that acquires (e.g., receives and / or learns) a first signaling schedule may or may not modify the corresponding UWB schedule based on the first signaling schedule. However, other specific implementations may be used.

[0031] The items and / or technologies described herein can provide one or more of the following capabilities, as well as others not mentioned. UWB sessions can be conducted in the presence of one or more other signaling sessions while avoiding interference between UWB and other signaling sessions. The success rate of UWB signal delivery within the range of other signal transmissions (e.g., unlocking a vehicle by a UE) can be improved. Cellular network sessions can, for example, enhance UE coverage and capabilities by operating on unlicensed frequency bands without impeding UWB execution. Other capabilities may be provided, and not every specific implementation of this disclosure is required to provide any, let alone all, of the capabilities discussed.

[0032] Obtaining the location of a mobile device accessing a wireless network can be useful for many applications, including emergency calls, personal navigation, consumer asset tracking, and locating friends or family members. In industrial applications, the location of mobile devices can be essential for asset tracking, robot control, and other kinematic operations that may require precise positioning of end effectors. Existing positioning methods include those based on measurements of radio signals transmitted from various devices or entities, including satellite spacecraft (SVs) and terrestrial wireless power sources in wireless networks, such as base stations and access points. Stations in a wireless network can be configured to transmit reference signals that enable mobile devices to perform positioning measurements. Positioning measurements can be used in various positioning methods that utilize reference signals transmitted by base stations for location determination in a manner similar to how LTE wireless networks utilize Positioning Reference Signals (PRS) and / or Cell-Specific Reference Signals (CRS).

[0033] Other positioning methods for obtaining the location of mobile devices (e.g., UWB devices) include one-sided two-way ranging (SS-TWR), two-sided two-way ranging (DS-TWR), or one-way ranging (OWR) for Time Difference of Arrival (TDOA) positioning methods. For example, SS-TWR involves measuring the round-trip delay of a single message from one device to another and the response transmitted back to the original device. DS-TWR is an extension of SS-TWR where two round-trip time measurements are used and these measurements are combined to give a TOF (Time of Flight) result with reduced error in the presence of uncorrected clock frequency offsets. TDOA is a technique for locating mobile devices (e.g., RFID devices) based on the relative arrival times of a single message or multiple messages. OWR is used for TDOA, and there are two TDOA scenarios. In the first TDOA scenario, messages are periodically broadcast by the mobile device to multiple fixed nodes that are synchronized in some way to make the arrival times comparable. Typically, the messages transmitted by the mobile device are referred to as flashes. In the second TDOA scenario, multiple synchronized nodes broadcast messages sequentially with known transmission time offsets relative to each other. For any pair of fixed synchronization nodes, the time difference of arrival of the flashing message in the first case or the broadcast message at the mobile device in the second case places the mobile device on the hyperbolic surface. Combining the results from multiple such pairs will produce the intersections between sets of hyperbolic surfaces, thus determining the location of the mobile device. In the second case, the transmission offset is considered when calculating the time difference of arrival of messages from the synchronization nodes.

[0034] The description herein can refer to a sequence of actions to be performed, for example, by elements of a computing device. The various actions described herein can be performed by special-purpose circuitry (e.g., an application-specific integrated circuit (ASIC)), by program instructions being executed by one or more processors, or by a combination of both. The sequence of actions described herein can be embodied in a non-transitory computer-readable medium storing a corresponding set of computer instructions that, when executed, will cause the associated processor to perform the functionality described herein. Therefore, the various examples described herein can be embodied in several different forms, all of which fall within the scope of this disclosure, including the claimed subject matter.

[0035] As used herein, the terms “User Equipment” (UE) and “Base Station” are not specific to or otherwise limited to any particular Radio Access Technology (RAT) unless otherwise indicated. Generally, a UE can be any wireless communication device (e.g., mobile phone, router, tablet computer, laptop computer, consumer asset tracking device, Internet of Things (IoT) device, etc.) used to communicate over a wireless communication network. A UE can be mobile or can (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 Terminal,” “Mobile Station,” “Mobile Equipment,” or variations thereof. Generally, 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 a UE, such as via a wired access network, WiFi, etc. ® Networks (e.g., based on IEEE (Institute of Electrical and Electronics Engineers) 802.11, etc.). In addition to exchanging information with each other via a network, or instead of exchanging information with each other via a network, two or more UEs can communicate directly.

[0036] Depending on the network in which the base station is deployed, the base station can operate according to one of several RATs when communicating with the UE. Examples of base stations include access points (APs), network nodes, Node Bs, evolved Node Bs (eNBs), or generic Node Bs (gNodeBs, gNBs). Furthermore, 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.

[0037] The UE can be represented by any of several types of devices, including but not limited to printed circuit boards (PCBs), compact flash memory devices, external or internal modems, wireless or wired phones, smartphones, tablet devices, consumer asset tracking devices, asset tags, etc. The communication link through which the UE can transmit signals to the RAN is called an uplink channel (e.g., reverse traffic channel, reverse control channel, access channel, etc.). The communication link through which the RAN can transmit signals to the UE is called a downlink 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 an uplink / reverse traffic channel or a downlink / forward traffic channel.

[0038] As used herein, depending on the context, the term "cell" or "sector" may correspond to one of a plurality of cells of a base station or to the base station itself. The term "cell" may refer to a logical communication entity used to communicate with a base station (e.g., on a carrier) and may be associated with identifiers to distinguish adjacent cells operating via the same or different carriers (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)). In some examples, a carrier may support multiple cells and may be configured with different cell types based on different protocol types that can provide access to different types of devices (e.g., Machine-Type Communication (MTC), Narrowband Internet of Things (NB-IoT), Enhanced Mobile Broadband (eMBB), or other protocol types). In some examples, the term "cell" may refer to a portion of the geographic coverage area on which a logical entity operates (e.g., a sector).

[0039] refer to Figure 1Examples of communication system 100 include UE 105, UE 106, radio access network (RAN) (here, fifth-generation (5G) next-generation (NG) RAN (NG-RAN) 135), 5G core network (5GC) 140, and server 150. UE 105 and / or UE 106 can be, for example, an IoT device, a location tracker device, a cellular phone, a vehicle (e.g., a car, truck, bus, ship, etc.), or another device. 5G network can also be referred to as a new radio (NR) network; NG-RAN 135 can be referred to as 5G RAN or NR RAN; and 5GC 140 can be referred to as NG core network (NGC). Standardization of NG-RAN and 5GC is underway within the 3rd Generation Partnership Project (3GPP). Therefore, NG-RAN 135 and 5GC 140 can follow current or future standards from 3GPP for 5G support. NG-RAN 135 can be another type of RAN, such as 3G RAN, 4G Long Term Evolution (LTE) RAN, etc. UE 106 can be configured and coupled similarly to UE 105 to transmit signals to and / or receive signals from similar other entities in system 100, but for simplicity of the figures, in Figure 1 Such signaling is not indicated in this document. Similarly, for simplicity, the discussion focuses on UE 105. Communication system 100 may utilize information from a constellation 185 of satellite spacecraft (SVs) 190, 191, 192, 193 from a satellite positioning system (SPS) such as GPS, GLONASS, Galileo, or BeiDou, or some other local or regional SPS (such as the Indian Regional Navigation Satellite System (IRNSS), the European Geostationary Navigation Coverage Service (EGNOS), or the Wide Area Augmentation System (WAAS)). Additional components of communication system 100 are described below. Communication system 100 may include additional or optional components.

[0040] like Figure 1As shown, NG-RAN 135 includes NR nodeBs (gNBs) 110a and 110b and a next-generation eNodeB (ng-eNB) 114, and 5GC 140 includes Access and Mobility Management Functions (AMF) 115, Session Management Functions (SMF) 117, Location Management Functions (LMF) 120, and Gateway Mobile Location Center (GMLC) 125. gNBs 110a, 110b, and ng-eNB 114 are communicatively coupled to each other, each configured to conduct bidirectional wireless communication with UE 105, and each communicatively coupled to AMF 115 and configured to conduct bidirectional communication with AMF. gNBs 110a, 110b, and ng-eNB 114 may be referred to as base stations (BS). AMF 115, SMF 117, LMF 120, and GMLC 125 are communicatively coupled to each other, and the GMLC is communicatively coupled to an external client 130. The SMF117 can be used as the initial contact point for the Service Control Function (SCF) (not shown) to create, control, and delete media sessions. Base stations (such as gNB 110a, 110b, and / or ng-eNB 114) can be macrocells (e.g., high-power cellular base stations), small cells (e.g., low-power cellular base stations), or access points (e.g., short-range base stations configured to use short-range technologies such as WiFi). ® WiFi ® Direct connection (WiFi) ® -D), Bluetooth ® ,Bluetooth ® Low power (BLE), Zigbee ® (e.g., one or more of gNB 110a, 110b and / or ng-eNB 114) can be configured to communicate with UE 105 via multiple carriers. Each of gNB 110a, 110b and / or ng-eNB 114 can provide communication coverage for a corresponding geographic area (e.g., cell). Each cell can be divided into multiple sectors based on the base station antennas.

[0041] Figure 1Generalized examples of various components are provided, wherein any or all of the components may be appropriately utilized, and each component may be repeated or omitted as needed. Specifically, although a UE 105 is illustrated, many UEs (e.g., hundreds, thousands, millions, etc.) may be utilized in communication system 100. Similarly, communication system 100 may include a larger (or smaller) number of SVs (i.e., more or fewer than the four SVs 190-193 shown), gNBs 110a and 110b, ng-eNB 114, AMF 115, external client 130, and / or other components. The illustrated connections connecting the various components in communication 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, the components may be rearranged, combined, separated, replaced, and / or omitted according to desired functionality.

[0042] Although Figure 1 A 5G-based network is illustrated, but similar network implementations and configurations can be used for other communication technologies such as 3G, Long Term Evolution (LTE), etc. The specific implementations described herein (for 5G technology and / or for one or more other communication technologies and / or protocols) can be used to transmit (or broadcast) directional synchronization signals, receive and measure directional signals at a UE (e.g., UE 105), and / or provide location assistance to UE 105 (via GMLC 125 or other location servers), and / or calculate the location of UE 105 at a location-capable device (such as UE 105, gNB 110a, 110b, or LMF 120) based on measurement parameters received at UE 105 for such directional transmissions. Gateway Mobile Location Center (GMLC) 125, Location Management Function (LMF) 120, Access and Mobility Management Function (AMF) 115, SMF 117, ng-eNB (eNodeB) 114, and gNB (gNodeB) 110a, 110b are examples and may be replaced by, or include, various other location server functions and / or base station functions, respectively.

[0043] System 100 is capable of wireless communication because its components can communicate directly or indirectly (at least sometimes using a wireless connection), for example, via gNB 110a, 110b, ng-eNB 114 and / or 5GC 140 (and / or one or more other devices not shown, such as one or more other transceiver base stations). For indirect communication, the communication can be modified during transmission from one entity to another, for example, by changing the header information of data packets, changing the format, etc. UE 105 may include multiple UEs and may be mobile wireless communication devices, but can communicate wirelessly as well as via wired connections. UE 105 can be any of a variety of devices, such as smartphones, tablets, vehicle-based devices, etc., but these are merely examples, as UE 105 does not need to be any of these configurations, and other configurations of UEs can be used. Other UEs may include wearable devices (e.g., smartwatches, smart jewelry, smart glasses, or head-mounted devices, etc.). Other UEs, whether currently existing or developed in the future, may also be used. In addition, other wireless devices (whether mobile or not) can be implemented within system 100 and can communicate with each other and / or with UE 105, gNB 110a, 110b, ng-eNB 114, 5GC 140, and / or external client 130. For example, such other devices may include Internet of Things (IoT) devices, medical devices, home entertainment and / or automation devices, etc. 5GC 140 can communicate with external client 130 (e.g., a computer system), for example, to allow external client 130 (e.g., via GMLC 125) to request and / or receive location information about UE 105.

[0044] UE 105 or other devices can be configured to communicate in various networks and / or for various purposes and / or using various technologies (e.g., 5G, Wi-Fi). ® Communication, multi-frequency Wi-Fi ® Communication, satellite positioning, and one or more types of communication (e.g., GSM (Global System for Mobile Communications), CDMA (Code Division Multiple Access), LTE (Long Term Evolution), V2X (vehicle-to-everything communication, e.g., V2P (vehicle-to-pedestrian), V2I (vehicle-to-infrastructure), V2V (vehicle-to-vehicle), etc.), IEEE 802.11p, etc.). V2X communication can be cellular (Cellular-V2X (C-V2X)) and / or WiFi. ®(For example, DSRC (Dedicated Short Range Connection)). System 100 can support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals simultaneously on multiple carriers. Each modulated signal can be a Code Division Multiple Access (CDMA) signal, a Time Division Multiple Access (TDMA) signal, an Orthogonal Frequency Division Multiple Access (OFDMA) signal, a Single Carrier Frequency Division Multiple Access (SC-FDMA) signal, etc. Each modulated signal can be transmitted on different carriers and can carry pilot, overhead information, data, etc. UEs 105 and 106 can communicate with each other via UE-to-UE sidelink (SL) communication by transmitting on one or more sidelink (SL) channels (such as the Physical Sidelink Synchronization Channel (PSSCH), Physical Sidelink Broadcast Channel (PSBCH), or Physical Sidelink Control Channel (PSCCH)). Direct device-to-device communication (without a network) is generally referred to as sidelink communication, without limiting the communication to a specific protocol.

[0045] UE 105 may include and / or may be referred to as a device, mobile device, wireless device, mobile terminal, terminal, mobile station (MS), Secure User Plane Location Enabled (SUPL) terminal (SET), or some other name. Furthermore, UE 105 may correspond to a cellular phone, smartphone, laptop computer, tablet device, PDA, consumer asset tracking device, navigation device, Internet of Things (IoT) device, health monitor, security system, smart city sensor, smart meter, wearable tracker, or some other portable or mobile device. Typically, although not mandatory, UE 105 may use one or more Radio Access Technologies (RATs) to support wireless communication, such as Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), LTE, High Rate Packet Data (HRPD), IEEE 802.11 WiFi, etc. ® (Also known as Wi-Fi) ® ),Bluetooth ® (BT), WiMax (Global Microwave Access) ® 5G New Radio (NR) (e.g., using NG-RAN 135 and 5GC 140), etc. UE 105 can use a Wireless Local Area Network (WLAN) to support wireless communication, which can connect to other networks (e.g., the Internet) using, for example, digital subscriber line (DSL) or packet cable. Using one or more of these RATs allows UE 105 (e.g., via elements of 5GC 140) Figure 1(not shown in the image), or possibly via GMLC 125, to communicate with external client 130 and / or allow external client 130 (e.g., via GMLC 125) to receive location information about UE 105.

[0046] UE 105 may include a single entity or may include multiple entities, such as in a personal area network, where the user may employ audio, video, and / or data I / O (input / output) devices, and / or body sensors, as well as separate wired or wireless modems. An estimate of the location of UE 105 may be referred to as location, location estimate, location fixed, fixed, positioning, location estimation, or location fixed, and may be geographic, providing the location coordinates of UE 105 (e.g., latitude and longitude), which may or may not include an elevation component (e.g., height above sea level; height above ground level, floor level, or basement level, or depth below). Alternatively, the location of UE 105 may be expressed as a municipal location (e.g., a postal address or designation of a point or smaller area within a building, such as a specific room or floor). The location of UE 105 may be represented as an area or volume (geographically or municipally defined) within which UE 105 is expected to be located with a certain probability or confidence level (e.g., 67%, 95%, etc.). The location of UE 105 can be represented as a relative location, which includes, for example, distance and direction relative to a known location. This relative location can be represented as relative coordinates (e.g., X, Y (and Z) coordinates) defined relative to an origin at a known location, which can be, for example, geographically, municipally, or with reference to a point, area, or volume indicated, for example, on a map, floor plan, or building plan. In the description contained herein, the use of the term "location" can include any of these variations unless otherwise indicated. When calculating the location of the UE, local x, y, and (possibly also) z coordinates are typically solved, and then (if necessary) the local coordinates are converted to absolute coordinates (e.g., with respect to latitude, longitude, and altitude above or below mean sea level).

[0047] UE 105 can be configured to communicate with other entities using one or more of a variety of technologies. UE 105 can be configured to indirectly connect to one or more communication networks via one or more device-to-device (D2D) peer-to-peer (P2P) links. D2D P2P links can use any suitable D2D radio access technology (RAT) such as LTE Direct (LTE-D), WiFi, etc. ® Direct connection (WiFi) ® -D), Bluetooth ®Support is provided. One or more UEs in a UE group utilizing D2D communication may be located within the geographic coverage area of ​​a Transmit / Receive Point (TRP) (such as one or more of gNB 110a, 110b and / or ng-eNB 114). Other UEs in such a group may be outside such geographic coverage area or may be unable to receive transmissions from the base station for other reasons. A UE group communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE can transmit to other UEs in the group. The TRP can facilitate the scheduling of resources for D2D communication. In other cases, D2D communication may be performed between UEs without involving the TRP. One or more UEs in a UE group utilizing D2D communication may be located within the geographic coverage area of ​​a TRP. Other UEs in such a group may be outside such geographic coverage area or may be unable to receive transmissions from the base station for other reasons. A UE group communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE can transmit to other UEs in the group. TRP can facilitate the scheduling of resources used for D2D communication. In other cases, D2D communication can be performed between UEs without involving TRP.

[0048] Figure 1 The base stations (BS) in NG-RAN 135 shown include NR Node Bs (referred to as gNB 110a and gNB 110b). Each pair of gNBs 110a and 110b in NG-RAN 135 can be interconnected via one or more other gNBs. Access to the 5G network is provided to UE 105 via wireless communication with one or more of the gNBs 110a and 110b. These gNBs can use 5G to provide wireless communication access to the 5GC 140 on behalf of UE 105. Figure 1 In this context, it is assumed that the serving gNB of UE 105 is gNB 110a, but another gNB (e.g., gNB 110b) may act as the serving gNB or as a secondary gNB to provide additional throughput and bandwidth to UE 105 if UE 105 moves to another location.

[0049] Figure 1The base station (BS) in NG-RAN 135 shown may include ng-eNB 114, also known as Next Generation Evolved Node B. ng-eNB 114 may be connected to one or more of gNBs 110a and 110b in NG-RAN 135 via one or more other gNBs and / or one or more other ng-eNBs. ng-eNB 114 may provide LTE radio access and / or evolved LTE (eLTE) radio access to UE 105. One or more of gNBs 110a, 110b and / or ng-eNB 114 may be configured to act as a location-only beacon, which may transmit signals to assist in determining the location of UE 105, but may not receive signals from UE 105 or other UEs.

[0050] gNB 110a, 110b, and / or ng-eNB 114 may each include one or more TRPs. For example, each sector within a cell of the BS may include a TRP, but multiple TRPs may share one or more components (e.g., a shared processor but with separate antennas). System 100 may include only macro TRPs, or system 100 may have different types of TRPs, such as macro TRPs, pico TRPs, and / or femto TRPs. Macro TRPs may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by terminals with service subscriptions. Pico TRPs may cover a relatively small geographic area (e.g., a pico cell) and may allow unrestricted access by terminals with service subscriptions. Femto or home TRPs may cover a relatively small geographic area (e.g., a femto cell) and may allow restricted access by terminals associated with that femto cell (e.g., terminals of users in a home).

[0051] Each of the gNBs 110a, 110b, and / or ng-eNB 114 may include a Radio Unit (RU), a Distributed Unit (DU), and a Central Unit (CU). For example, the gNB 110b includes RU 111, DU 112, and CU 113. RU 111, DU 112, and CU 113 define the functionality of the gNB 110b. Although the gNB 110b is shown as having a single RU, a single DU, and a single CU, a gNB may include one or more RUs, one or more DUs, and / or one or more CUs. The interface between CU 113 and DU 112 is referred to as the F1 interface. RU 111 is configured to perform digital front-end (DFE) functions (e.g., analog-to-digital conversion, filtering, power amplification, transmit / receive) and digital beamforming, and includes part of the physical (PHY) layer. RU 111 may perform DFE using massive MIMO and may be integrated with one or more antennas of the gNB 110b. DU 112 hosts the Radio Link Control (RLC), Media Access Control (MAC), and Physical Layer of gNB 110b. A DU can support one or more cells, and each cell is supported by a single DU. The operation of DU 112 is controlled by CU 113. CU 113 is configured to perform functions for delivering user data, mobility control, radio access network sharing, location, session management, etc., although some functions are only assigned to DU 112. CU 113 hosts the Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP) of gNB 110b. UE 105 can communicate with CU 113 via the RRC, SDAP, and PDCP layers, with DU 112 via the RLC, MAC, and PHY layers, and with RU 111 via the PHY layer.

[0052] As pointed out, although Figure 1 The diagram depicts nodes configured to communicate according to 5G communication protocols, but nodes configured to communicate according to other communication protocols (such as, for example, LTE or IEEE 802.11x) can also be used. For instance, in an evolved packet system (EPS) providing LTE radio access to UE 105, the RAN may include an evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN), which may include base stations containing evolved Node Bs (eNBs). The core network for the EPS may include an evolved packet core (EPC). The EPS may include the E-UTRAN plus the EPC, where the E-UTRAN corresponds to... Figure 1 NG-RAN 135 in the figure and EPC corresponds to 5GC 140 in the figure.

[0053] gNB 110a, 110b, and ng-eNB 114 can communicate with AMF 115; for location functionality, AMF communicates with LMF 120. AMF 115 can support UE 105 mobility (including cell changes and handover) and can participate in supporting signaling connections with UE 105 and (possibly) data and voice bearers for UE 105. LMF 120 can communicate directly with UE 105, for example, wirelessly, or directly with gNB 110a, 110b, and / or ng-eNB 114. LMF 120 can support UE 105 positioning when UE 105 accesses NG-RAN 135, and can support various positioning procedures / methods, such as Auxiliary GNSS (A-GNSS), Observation Time Difference of Arrival (OTDOA) (e.g., Downlink (DL) OTDOA or Uplink (UL) OTDOA), Round Trip Time (RTT), Multi-Cell RTT, Real-Time Kinematics (RTK), Precise Point Positioning (PPP), Differential GNSS (DGNSS), Enhanced Cell ID (E-CID), Angle of Arrival (AoA), Angle of Departure (AoD), and / or other positioning methods. LMF 120 can process, for example, location service requests for UE 105 received from AMF 115 or GMLC 125. LMF 120 can connect to AMF 115 and / or GMLC 125. LMF 120 can be referred to by other names, such as Location Manager (LM), Location Function (LF), Commercial LMF (CLMF), or Value-Added LMF (VLMF). The node / system implementing LMF 120 may additionally or alternatively implement other types of location support modules, such as an Enhanced Serving Mobility Location Center (E-SMLC) or a Secure User Plane Location (SUPL) Location Platform (SLP). At least a portion of the location functionality (including the derivation of the location of UE 105) may be performed at UE 105 (e.g., using signal measurements obtained by UE 105 against signals transmitted by radio nodes (such as gNB110a, 110b, and / or ng-eNB 114), and / or auxiliary data provided to UE 105, for example, by LMF 120). AMF 115 may serve as a control node for handling signaling between UE 105 and 5GC 140 and may provide QoS (Quality of Service) streaming and session management. AMF 115 may support the mobility of UE 105 (including cell changes and handover) and may participate in supporting signaling connections with UE 105.

[0054] Server 150 (e.g., a cloud server) is configured to obtain the location estimate of UE 105 and provide it to external client 130. Server 150 may be configured, for example, to run a microservice / service for obtaining the location estimate of UE 105. Server 150 may, for example (e.g., by sending a location request to it), pull the location estimate from one or more of UE 105, gNB 110a, 110b (e.g., via RU 111, DU 112, and CU 113) and / or ng-eNB 114 and / or LMF 120. As another example, one or more of UE 105, gNB 110a, 110b (e.g., via RU 111, DU 112, and CU 113) and / or LMF 120 may push the location estimate of UE 105 to server 150.

[0055] GMLC 125 can support location requests for UE 105 received from external client 130 via server 150, and can forward such location requests to AMF 115 for forwarding to LMF 120, or can forward the location request directly to LMF 120. A location response from LMF 120 (e.g., containing a location estimate for UE 105) can be returned to GMLC 125 directly or via AMF 115, and GMLC 125 can then return the location response (e.g., containing the location estimate) to external client 130 via server 150. GMLC 125 is shown connected to both AMF 115 and LMF 120, but in some specific implementations it may not be connected to either AMF 115 or LMF 120.

[0056] like Figure 1 As a further example, the LMF 120 can use the new radio positioning protocol A (which may be referred to as NPPa or NRPPa) to communicate with gNB 110a, 110b and / or ng-eNB 114, which can be defined in 3GPP Technical Specification (TS) 38.455. NRPPa can be the same as, similar to or an extension of the LTE Positioning Protocol A (LPPa) defined in 3GPP TS 36.455, where NRPPa messages are transmitted via AMF 115 between gNB 110a (or gNB 110b) and LMF 120, and / or between ng-eNB 114 and LMF 120. Figure 1As a further example, LMF 120 and UE 105 can communicate using the LTE Location Protocol (LPP), which is defined in 3GPP TS 36.355. LMF 120 and UE 105 can also communicate using a new radio positioning protocol (which may be referred to as NPP or NRPP), which may be the same as, similar to, or an extension of LPP. Here, LPP and / or NPP messages can be transmitted between UE 105 and LMF 120 via AMF 115 and UE 105's serving gNB 110a, 110b, or serving ng-eNB 114. For example, LPP and / or NPP messages can be transmitted between LMF 120 and AMF 115 using the 5G Location Services Application Protocol (LCS AP), and between AMF 115 and UE 105 using the 5G Non-Access Stratum (NAS) protocol. The LPP and / or NPP protocols can be used to support the location of UE 105 using UE-assisted and / or UE-based positioning methods (such as A-GNSS, RTK, OTDOA, and / or E-CID). The NRPPa protocol can be used to support the location of UE 105 using network-based positioning methods (such as E-CID) (e.g., when used in conjunction with measurements obtained by gNB 110a, 110b, or ng-eNB 114) and / or can be used by LMF 120 to obtain location-related information from gNB 110a, 110b, and / or ng-eNB 114, such as defining parameters sent by directional SS or PRS from gNB 110a, 110b, and / or ng-eNB 114. LMF 120 can be co-located or integrated with gNB or TRP, or can be configured to be located away from gNB and / or TRP and communicate directly or indirectly with gNB and / or TRP.

[0057] Using a UE-assisted positioning method, UE 105 can obtain location measurements and transmit these measurements to a location server (e.g., LMF 120) for calculating a location estimate for UE 105. For example, location measurements may include one or more of the following: Received Signal Strength Indication (RSSI), Round-Trip Time (RTT), Reference Signal Time Difference (RSTD), Reference Signal Received Power (RSRP), and / or Reference Signal Received Quality (RSRQ) for gNB 110a, 110b, ng-eNB 114, and / or WLAN AP. Location measurements may additionally or alternatively include measurements of GNSS pseudorange, code phase, and / or carrier phase for SV 190-193.

[0058] Using a UE-based positioning method, UE 105 can obtain a location measurement (e.g., which may be the same as or similar to the location measurement of a UE-assisted positioning method) and can calculate the location of UE 105 (e.g., by means of auxiliary data received from a location server (such as LMF 120) or broadcast by gNB 110a, 110b, ng-eNB 114 or other base stations or APs).

[0059] Using a network-based positioning method, one or more base stations (e.g., gNB 110a, 110b and / or ng-eNB 114) or APs can obtain location measurements (e.g., measurements of RSSI, RTT, RSRP, RSRQ, or Time of Arrival (ToA) of signals transmitted by UE 105) and / or can receive measurements obtained by UE 105. One or more base stations or APs can transmit the measurements to a location server (e.g., LMF 120) for calculating a location estimate for UE 105.

[0060] The information provided to the LMF 120 by the gNB 110a, 110b and / or ng-eNB 114 using NRPPa may include timing and configuration information for directing SS or PRS transmissions, as well as location coordinates. The LMF 120 may provide some or all of this information as supplementary data to the UE 105 in LPP and / or NPP messages via NG-RAN 135 and 5GC140.

[0061] The LPP or NPP message transmitted from LMF 120 to UE 105 can command UE 105 to perform any of a variety of tasks depending on the desired functionality. For example, the LPP or NPP message may contain instructions for UE 105 to obtain measurements of GNSS (or A-GNSS), WLAN, E-CID, and / or OTDOA (or some other positioning method). In the case of E-CID, the LPP or NPP message may command UE 105 to obtain measurements supported by one or more of gNB 110a, 110b, and / or ng-eNB 114 (or by some other type of base station such as eNB or WiFi). ® One or more measurement parameters (e.g., beam ID, beamwidth, average angle, RSRP, RSRQ measurements) of directional signals transmitted within a specific cell supported by the AP. UE 105 can transmit these measurement parameters back to LMF 120 via serving gNB110a (or serving ng-eNB 114) and AMF 115 in an LPP or NPP message (e.g., within a 5G NAS message).

[0062] As noted, while a communication system 100 is described in relation to 5G technology, the communication system 100 can be implemented to support other communication technologies (such as GSM, WCDMA, LTE, etc.) for supporting and interacting with mobile devices (such as UE 105) (e.g., to provide voice, data, location, and other functionalities). In some such specific implementations, the 5GC 140 can be configured to control different air interfaces. For example, the 5GC 140 can use non-3GPP interoperability functions (N3IWF) within the 5GC 140. Figure 1 (Not shown) Connected to a WLAN. For example, the WLAN may support IEEE 802.11 WiFi for UE 105. ® Access, and may include one or more WiFi networks. ® AP. Here, the N3IWF can connect to the WLAN and other components in 5GC 140, such as AMF 115. In some examples, both NG-RAN 135 and 5GC 140 can be replaced by one or more other RANs and one or more other core networks. For example, in EPS, NG-RAN 135 can be replaced by E-UTRAN containing eNBs, and 5GC 140 can be replaced by EPC containing a Mobility Management Entity (MME) instead of AMF 115, an E-SMLC instead of LMF 120, and a GMLC that can be similar to GMLC 125. In such EPS, the E-SMLC can use LPPa instead of NRPPa to transmit location information to and receive location information from eNBs in the E-UTRAN, and can use LPP to support UE 105's positioning. In these other examples, the location of UE 105 using directional PRS can be supported in a manner similar to that described herein for 5G networks. The difference is that the functions and procedures described herein for gNB 110a, 110b, ng-eNB114, AMF 115, and LMF 120 can, in some cases, be alternatively applied to other network elements, such as eNBs and WiFi. ® AP, MME, and E-SMLC.

[0063] As noted, in some examples, positioning functionality can be achieved at least in part using directional SS or PRS beams transmitted by base stations (such as gNB 110a, 110b and / or ng-eNB 114) at the location of the UE (e.g., whose location is to be determined). Figure 1 Within the range of UE 105. In some instances, the UE can use directional SS or PRS beams from multiple base stations (such as gNB 110a, 110b, ng-eNB 114, etc.) to calculate the UE's location.

[0080] Also refer to Figure 6 Network entity 600 includes a processor 610, a transceiver 620, and a memory 630 that are communicatively coupled to each other via a bus 640. Even when mentioned in the singular, network entity 600 may include one or more network entities, processor 610 may include one or more processors, transceiver 620 may include one or more transceivers (e.g., one or more transmitters and / or one or more receivers), and memory 630 may include one or more memories.

Memory 630 may be configured similarly to memory 330, for example, including software having processor-readable instructions configured to cause processor 610 to perform functions.

[0081] The description herein may refer to the functions performed by processor 610, but this includes other specific implementations, such as the case where processor 610 performs software and / or firmware (stored in memory 630). The description herein may refer to the functions performed by network entity 600 as an abbreviation for the functions performed by one or more suitable components of network entity 600 (e.g., processor 610 and memory 630). Processor 610 (possibly in conjunction with memory 630 and, appropriately, transceiver 620) may include RAT unit 650. RAT unit 650 may be configured to schedule RAT signaling based on UWB scheduling information received from the UE. RAT unit 650 is further discussed below, and any functions that may be generally referred to as the functions performed by processor 610 or generally referred to as the functions performed by network entity 600, wherein network entity 600 is configured to perform these functions, are described.

[0082] Also refer to Figure 7The signaling environment 700 includes a base station 710 and UEs 720 and 730. Each of UEs 720 and 730 may be an example of UE 500. In this example, UE 720 is a smartphone, and UE 730 is a vehicle or at least a part of such a vehicle. Base station 710 may include one or more of TRPs 300 and may be configured to provide RAT signals, for example, it may be used as a base station for a cellular network. UE 720 may be configured to communicate with base station 710 via RAT signaling (e.g., the transmission (e.g., switching) of RAT signal 740). UE 720 may obtain (e.g., receive and / or learn from base station 710) a first signal transmission schedule (e.g., RAT transmission schedule). The RAT schedule (which may be referred to as the RAT transmission schedule) may include indications of timing for RAT frames, subframes within a corresponding frame, time slots within a corresponding subframe, and symbols within a corresponding time slot. UEs 720 and 730 can be configured to communicate with each other via UWB signaling (e.g., the delivery of UWB signal 750). New spectrum can be used for next-generation (e.g., 6G) RAT signals, and this new spectrum may overlap with the UWB spectrum. Using the same spectrum as UWB devices for RAT signals can interfere with UWB signals, especially since UWB signal transmit power is -14.3 dBm or less, while RAT signal transmit power can be around 40 dBm. Interference with UWB communication may be a concern for UWB device manufacturers (e.g., vehicle manufacturers who have used UWB signaling to achieve a 99.9% success rate in enabling digital car key functionality (e.g., unlocking, locking, starting, and / or locking the vehicle). To help achieve a 99.9% success rate, UWB unit 550 and / or RAT unit 650 can help mitigate or avoid interference between RAT signals (e.g., FR3 signals with frequencies between 7.125 GHz and 24.25 GHz) and UWB signals (signals with frequencies between 3.1 GHz and 10.6 GHz). To help mitigate or avoid such interference, UWB unit 550 and RAT unit 650 can implement one or more coexistence techniques. UE 720 can connect to a RAT network and / or can be used as a UWB controller. As a complement or alternative to base station 710, signaling environment 700 may include wireless communication device 760 (and possibly one or more other wireless signaling devices). The wireless signaling device can be configured to transmit (e.g., send and / or receive) signals 770 that can interfere with one or more signals received by UE 720 (e.g., RAT signals (e.g., SL signals) and / or UWB signals, etc.). Alternatively, UE 720 may transmit a signal 780 that may interfere with UWB signal 750 (e.g., one or more RAT signals in RAT signal 740 and / or one or more other UWB signals, etc.).

[0083] UWB devices can use pulse-based radio signaling (e.g., short-pulse UWB) instead of OFDM-based signaling (multi-band OFDM UWB (MB-OFDM-UWB)). Short-pulse UWB signaling transmits energy per bit spread across the entire UWB channel bandwidth (e.g., 1.37 GHz, 4 GHz, etc.) with varying pulse amplitude and / or pulse polarity without using an RF carrier, while MB-OFDM-UWB uses a 4 MHz bandwidth channel to transmit each bit.

[0084] Using short-pulse UWB signaling systems offers several advantages over MB-OFDM-UWB signaling systems and other OFDM-based systems. For example, short-pulse UWB signaling systems provide better fading characteristics compared to MB-OFDM-UWB signaling systems (e.g., Gaussian modeling versus Rayleigh modeling fading, and / or less than 1% of the channel experiencing fading of 2 dB or more). As other examples, short-pulse UWB signaling systems operate more accurately than MB-OFDM-UWB signaling systems without FEC (forward error correction), without RAKE processing, with lower peak-to-average RF, and / or longer battery life. Short-pulse UWB also does not use traditional modulation and demodulation techniques such as Fast Fourier Transform (FFT), but can use time-domain or space-time processing techniques. Short-pulse UWB can utilize various pulse shapes (e.g., Gaussian pulses, single-cycle pulses, Hermitian pulses, etc.), and the shape used can be selected based on pulse characteristics in the time and frequency domains, as well as other factors such as bandwidth utilization, interference mitigation, power spectral density, multipath fading and inter-symbol interference, design complexity, power consumption, distance, and trade-offs for ultrafast sampling. In some cases, short-pulse UWB can benefit from high-speed analog-to-digital converters (ADCs) and high-speed digital-to-analog converters (DACs) to handle the extremely wide bandwidth used; however, other methods exist for handling ultrafast sampling, such as using time-hopping techniques and direct sequence decoding techniques.

[0085] Multi-band OFDM UWB divides the spectrum into several frequency sub-bands and applies OFDM within each band; other OFDM systems typically operate within fixed frequency bands. The complex waveform created by combining multiple sub-bands generates the final waveform used for transmission in MB-OFDM-UWB. Multi-band OFDM UWB also differs from other OFDM systems in that it does not use guard intervals; it uses simpler modulation schemes, such as binary phase-shift keying (BPSK) or quadrature phase-shift keying (QPSK) with 64 or 256 quadrature amplitude modulation (QAM); it uses constant power levels; while other OFDM systems can use power control to change channel conditions, etc.

[0086] Also refer to Figure 8A and Figure 8B UWB devices can be controllers or subjects, and can be initiators or responders. A UWB device is a device, such as a UE, configured to use UWB signals to communicate with another UWB device. A UWB controller (which may be referred to herein as the controller) is an Enhanced Ranging Device (ERDEV) configured to control a UWB ranging session, define ranging parameters, and provide ranging parameters to another UWB device by transmitting Ranging Control Messages (RCMs). RCMs can be transmitted via a UWB link and / or via another communication link (e.g., WiFi or NR (New Radio)). RCMs contain metrics on how the UWB session will function (e.g., the selected channel, transmit power, timing information). The controller can be configured to update the ranging parameters during an ongoing session by, for example, periodically transmitting Ranging Control Update Messages (RCUMs). A UWB subject (which may be referred to herein as the subject) is an ERDEV configured to use the ranging parameters received from the controller in the RCM or RCUM to send and / or receive UWB ranging messages. An initiator is an ERDEV that initiates a ranging transfer by transmitting a Ranging Initiation Message (RIM) to a responder using information from the RCM. A controller or controller can be either the initiator or the responder. A responder is an ERDEV that responds to a RIM received from the initiator by transmitting a Ranging Response Message (RRM) to the initiator. The RIM and / or RRM can be measured for positioning, for example, to determine Time of Arrival (ToA) estimates and / or Angle of Arrival (AoA) estimates. The initiator and responder provide bidirectional ranging, which corrects for clock skew errors between the initiator and responder, improving the accuracy of the ToA estimate and the overall distance (and therefore positioning) estimate. For example, as... Figure 8A As shown, controller 810 transmits RCM 831 to controller 820. Controller 810, acting as initiator 812, transmits RIM 832 to controller 820, acting as responder 822. Responseer 822 responds to RIM 832 by transmitting RRM 833 to initiator 812. As another example, as... Figure 8B As shown, controller 810 transmits RCM 831 to controller 820. Controller 820, acting as initiator 812, transmits RIM 832 to controller 810, acting as responder 822. Responder 822 responds to RIM 832 by transmitting RRM 833 to initiator 812.

[0087] Also refer to Figure 9A UWB session consists of consecutive ranging blocks, which are time blocks. Each ranging block (such as ranging block 910) can have a duration between 200ms and 250ms. Each ranging block includes multiple rounds, for example, rounds 9201, 9202, 9203...920. N-1 920 N Each round lasts between 10ms and 20ms. Rounds 9201-920 N Each of the components comprises ranging time slots 930, with each time slot within 930 having a duration between 1 ms and 2.66 ms. The ranging packets within a time slot may have an SP3 format (similar to PRS) and may have a duration of up to 1 ms, for example, approximately 150 μs, while the remainder of the time slot may be reserved for handling delays. Rounds 9201-920 are located within ranging block 910. N The number N can be configured by the UWB controller (e.g., controller 810). Transmission for any given ranging block occurs within a selected round of the rounds, during which neither UWB device in the session transmits during the other (unselected) rounds. The selected round for any particular ranging block can be statically configured by the controller in the RCM, or it can be selected according to a hopping mode. The hopping mode can be a formula known to both the initiator and the responder, and the initiator and the responder can independently apply this formula to transmit and receive ranging messages. The round structure and the selection of rounds can help avoid interference between UWB sessions, as multiple UWB sessions can exist close to each other without any central control over the multiple sessions.

[0088] Also refer to Figure 10 Ranging round 1000 is divided into time slots that can be used for various purposes. For example, the first time slot 1010 can be used for the ranging control phase and is therefore reserved for transmitting RCM. A set of time slots 1020 is assigned to the ranging phase and is used by the initiator and responder to transmit RIM and RRM respectively in alternating time slots. Multiple RIMs and RRMs can be transmitted to achieve the desired result (e.g., one or more measurements with sufficient accuracy). An optional measurement reporting phase may include time slot 1030, during which the initiator and responder can transmit measurements that can be used to calculate the distance between the initiator and responder. The duration of a RAT frame can be 10 ms, and therefore if ranging round 1000 comprises 10 time slots, each with a duration of approximately 1 ms, the duration of a RAT frame is approximately the duration of ranging round 1000. Similarly, RAT subframes can be 1 ms long, which is the same as the minimum duration of a UWB ranging time slot.

[0089] Also refer to Figure 11The signaling and processing flow 1100, used to determine and provide UWB scheduling based on another signal transmission schedule, includes the stages shown. Flow 1100 is an example flow and not a limiting one. Flow 1100 can be modified, for example, by adding one or more messages and / or one or more stages and / or splitting one or more messages and / or one or more stages into multiple messages and / or stages. In flow 1100, signals can be passed between radio signaling device 1101, UE 1103, and UE 1104. Radio signaling device 1101 may include, for example, a UE, or a core network entity (CNE), or a TRP, or a combination of CNE and TRP, etc. CNE may be an example of network entity 600. TRP may be an example of TRP 300. Radio signaling device 1101 may be an example of UE 500 or another device capable of transmitting (e.g., transmitting and / or receiving) radio signals. Radio signaling device 1101 may transmit radio signals non-exclusively and may transmit both radio signals and guidance (e.g., wired) signals. Wireless signaling device 1101 includes at least one radio component (each radio component is part of a transmitter, receiver, or transceiver) for wireless signal transmission. UEs 1103 and 1104 can be examples of UE 500, where UE 1103 acts as a UWB controller and UE 1104 acts as a UWB controller. For example, UE 1103 may be intended to initiate a UWB ranging session with vehicles in a low-vehicle-density area (e.g., near a house in a suburban community). For example, if UE 1103 is part of or connected to a network entity (e.g., a server) via wireless signaling device 1101, UE 1103 may be referred to as a connected UE.

[0090] At stage 1110, UE 1103 may obtain a first signaling schedule. For example, at sub-stage 1112, radio signaling device 1101 may generate a first signaling schedule, such as a RAT schedule or a UWB schedule, but for this discussion, we assume a RAT schedule. A RAT schedule may include indications of timing for RAT frames, subframes within a corresponding frame, time slots within a corresponding subframe, and symbols within a corresponding time slot. The RAT schedule includes parameters for downlink (DL) signaling (e.g., channel, time slot offset, etc.). Radio signaling device 1101 may determine the RAT schedule based on one or more parameters of the UWB session transmitted by UE 1103, for example, as described below regarding... Figure 13This is discussed in stage 1310. If the radio signaling device 1101 includes a CNE and a TRP, the CNE can determine a RAT scheduling message with a RAT schedule and send the RAT scheduling message to the TRP for radio transmission by the TRP, and the RAT scheduling message can be received by one or more of UEs 1103 and 1104. The radio signaling device 1101 can send a first signaling schedule message 1114 with a first signaling schedule, and message 1114 can be received by UE 1103. The radio signaling device 1101 can send the first signaling schedule message 1114 to UE 1103 (e.g., periodically) (e.g., from the TRP in DCI (Downlink Control Information) embedded in the PDCCH (Physical Downlink Control Channel). As another example, the radio signaling device 1101 (e.g., another UE) can generate the first signaling schedule as a sidelink signaling schedule or a UWB signaling schedule. In this scenario, the radio signaling device 1101 may include a UE, such as UE 1103. The radio signaling device 1101 may determine the first signaling schedule based on one or more parameters of the UWB session provided by UE 1103, for example, as described below. Figure 13 This is discussed in stage 1310. The radio signaling device 1101 may transmit a first signal transmission schedule message 1114 with a first signal transmission schedule, and the UE 1103 may receive and decode message 1114 to obtain the first signal transmission schedule. As another example, the UE 1103 may obtain the first signal transmission schedule by receiving a first signal 1116 (e.g., a RAT signal (e.g., a DL signal, SL signal) or a UWB signal) transmitted by the radio signaling device 1101 according to (e.g., indicated in the first signal transmission schedule message 1114) the first signal transmission schedule. At sub-stage 1118, the UE 1103 may listen to (e.g., scan) the channel of the first signal 1116, measure the first signal 1116, determine the first signal 1116 that satisfies an interference threshold, and detect the pattern of the first signal 1116 that satisfies the interference threshold. For example, the first signal that satisfies the interference threshold may be a first signal received with a signal strength exceeding a signal strength interference threshold, or a first signal having a SINR (signal-to-interference-plus-noise ratio) exceeding a SINR interference threshold. For example, the signal strength interference threshold could be -85dBm (which could be approximately the receiver sensitivity value), corresponding to an SINR that drops below (not exceeding) -10dB below the SINR threshold.

[0091] At stage 1120, a second signal transmission schedule (in this case, a UWB signal transmission schedule) based on the first signal transmission schedule (obtained at stage 1110) can be generated and transmitted to UE 1104. For example, at sub-stage 1122, UE 1103, acting as a UWB controller, can generate a UWB schedule based on the first signal transmission schedule (e.g., a RAT signal transmission schedule (such as a sidelink signal transmission schedule), or a UWB signal transmission schedule, etc.). UE 1103's UWB unit 550 can use one or more parameters of the first signal transmission schedule to select the UWB round, time slot, and (appropriately) the UWB transmission offset within these time slots (relative to the UWB signaling available between UEs 1103 and 1104 to avoid signal overlap (in time and frequency, directly or via harmonics) of UWB and other signals (e.g., RAT signals, UWB signals, etc.)). This helps avoid interference from other signals to the UWB signal. The UWB transmission offset is a time offset for ranging packets within a time slot from the boundary (e.g., the start) of that time slot. The offset delays transmission within the time slot, where the ranging packet duration is approximately 150 μs and the time slot is at least 1 ms. UE 1103 may synchronize with radio signaling device 1101 (to which UE 1103 is connected) and establish a time reference for the UWB session. For example, the time boundaries of the UWB session and another signaling session (e.g., RAT session) are aligned, or any time offset between the boundaries of another signaling session and the UWB session is known to UE 1103. UE 1103 may generate a UWB signaling schedule based on the selected UWB round and time slot, and send the UWB schedule as a second signaling schedule in a second signaling schedule message 1124 (which may be RCM or RCUM and may be referred to as a ranging control message) to UE 1104, which will act as the UWB controller. The second signaling schedule message 1124 may indicate parameters of the second signaling schedule, such as one or more signaling offsets. The UWB unit 550 may select the ranging block duration, the number of ranging rounds in each ranging block, and the number of ranging time slots within each ranging round. The UWB unit 550 may be configured to make these selections based on the latency requirements of the UWB session and / or one or more durations of the signaling schedule of another signaling session (e.g., RAT frame duration, RAT subframe duration, and / or RAT symbol duration, or UWB ranging block duration, UWB ranging round duration, and / or UWB ranging time slot duration). Each ranging block (between 200ms and 250ms) may only perform one UWB ranging measurement, and therefore, if latency requirements are stringent, the UE 1103 may set a small block size (duration).For example, equipment manufacturers (e.g., automotive companies) can apply shorter ranging blocks to reduce latency to the desired level for unlocking a vehicle. This can also improve estimation accuracy due to more frequent measurements, which may result in higher power consumption. The UWB unit 550 can select a set of round indices (across ranging blocks), a set of slot indices within each of the selected rounds, and a set of slot offsets within each of the selected slots, which do not overlap (in time and frequency) with one or more active signaling transmissions in another signaling session (i.e., a UWB session other than that between UEs 1103 and 1104), and UWB transmissions are scheduled to occur during these slot offsets.

[0092] At stage 1130, UEs 1103 and 1104 may transmit one or more UWB signals 1132 between them. The UWB signals 1132 may be transmitted according to a second signaling schedule generated at stage 1120 to avoid interference with the first signal 1116, thereby enabling the desired functionality of the UWB signals 1132. For example, UWB communication can be implemented in environments with dense wireless devices, such as to unlock vehicles using, for example, RAT communication and / or UWB communication in the presence of many vehicles.

[0093] Also refer to Figure 12UE 1103 (acting as a UWB controller) can schedule UWB sessions to avoid interference with RAT transmissions. UE 1103 (e.g., UWB unit 550) can generate UWB schedule 1210 such that the active / ongoing transmission times of RAT schedule 1220 (overlapping frequencies) do not overlap with the active / ongoing transmission times of UWB schedule. Therefore, RAT signaling and UWB signaling can operate in TDM (Time Division Multiplexing) mode at the RAT frame level. RAT schedule 1220 is divided into frame 1221, subframes 1222 within frame 1221, one or more time slots 1223 within each subframe of subframe 1222, and symbols 1224 within each time slot 1223 (e.g., 14 symbols in each time slot 1223), and UWB schedule is divided into blocks, rounds within blocks, and time slots within rounds. Ranging rounds can be scheduled by UE 1103 during inactive RAT frames. UE 1103 can use knowledge of the DRX (Discontinuous Receive) mode (and the corresponding unused RAT frames) to determine UWB scheduling (e.g., where UWB ranging rounds are scheduled within unused RAT frames). At a finer-grained scheduling level, UE 1103 can schedule UWB ranging slots and transmit offsets to overlap ranging packets with one or more inactive symbols within a RAT slot (which may have been scheduled for uplink (UL) or flexible) to help avoid interference. UWB ranging packets are contained within UWB ranging slots and have a duration of at least 150 μs, RAT symbols have a duration of 66.67 μs or less (where the length depends on the parameter set / SCS (subcarrier spacing)), and UWB ranging packets can be scheduled to overlap with inactive RAT symbols. Figure 12 As illustrated in the example, in the case of a 15kHz SCS, RAT slot 1223 will be 1ms, and therefore each RAT subframe 1222 (which is 1ms) will contain a single RAT slot. For example, UWB ranging packet 1230 (UWB RP) can be scheduled to overlap with a portion of inactive symbols 1240, 1241, and 1242 of RAT scheduling 1220 based on the offset 1250 of this ranging packet within UWB slot 1260, in order to avoid overlap with active RAT symbol 1270.

[0094] about Figure 11 and Figure 12The techniques discussed may be particularly useful for inter-device coexistence, thereby avoiding interference from signal transmissions from different devices. The techniques discussed herein can also be used to facilitate intra-device coexistence (IDC). Due to the extreme proximity of multiple radio transceivers within a single UE operating on the same and / or adjacent frequencies or subharmonic frequencies, the interference power received by a co-located receiver from the transmitter may be much higher than the receiver is configured to receive the desired signal. This paper discusses techniques for time-division multiplexing of signaling for different co-located devices (e.g., transmitters and receivers of corresponding transceivers), for example, by adapting RAT scheduling to UWB scheduling. (For LTE and Bluetooth) ® Previous technologies for the coexistence of LTE and ISM / GNSS used some subframes for LTE and for Bluetooth. ® Or the assignment of other subframes in ISM / GNSS.

[0095] Also refer to Figure 13 The signaling and processing flow 1300, used to determine and provide the first signaling schedule based on the second signaling schedule for the IDC, includes the stages shown, and wherein the second signaling schedule is a UWB signaling schedule. Flow 1300 is an example flow and not a limiting one. Flow 1300 can be modified, for example, by adding one or more messages and / or one or more stages and / or splitting one or more messages and / or one or more stages into multiple messages and / or stages. In flow 1300, signaling is passed between the radio signaling device 1330 (which includes, herein, CNE / scheduler 1301 and TRP 1302) and the UE 1303. CNE / scheduler 1301 may be an example of network entity 600. TRP 1302 may be an example of TRP 300. UE 1303 may be an example of UE 500, wherein UE 1303 acts as a UWB controller. For example, UE 1303 may intend to initiate a UWB ranging session with a vehicle. In the example shown, radio signaling device 1330 includes CNE / scheduler 1301 and TRP 1302. Radio signaling device 1330 may alternatively include a UE or another device, for example, for SL signaling and / or UWB signaling. The discussion of procedure 1300 focuses on the illustrated example of radio signaling device 1330 including CNE / scheduler 1301 and TRP 1302; however, procedure 1300 is applicable to other specific implementations, such as where radio signaling device 1330 is a UE.

[0096] At phase 1310, UE 1303 determines the UWB session parameters for the UWB scheduling (second signaling scheduling), configures the UWB controller (e.g., a vehicle) for the UWB session, and reports the UWB scheduling to TRP 1302. At sub-phase 1312, UE 1303 (e.g., UWB unit 550) determines the parameters for the UWB scheduling, which may include the start of the UWB ranging block, the periodicity of the UWB ranging block, the number and duration of ranging rounds within the ranging block, the number and duration of ranging time slots within the ranging rounds, the ranging hopping pattern, and the time slot allocation within the ranging rounds. To enable preemptive communication between the UWB scheduling and the radio signaling device 1330 (here, CNE / scheduler 1301), the UWB session parameters may be limited to a single set of parameters (the set of parameters known to be supported by the controller). Alternatively, these parameters may have been pre-configured and stored (e.g., in memory 530) from an earlier session between the same two devices (i.e., UE 1303 and the controller). UE 1303 may send a UWB scheduling message 1314 indicating one or more of the parameters for UWB scheduling, and TRP 1302 may forward the UWB scheduling to radio signaling device 1330, in this example, CNE / scheduler 1301, in a UWB scheduling message 1316. UE 1303 may respond to triggers (e.g., movement of UE 1303, approximate location of UE 1303 within the trigger zone, or UE 1303 receiving Bluetooth signals periodically transmitted to UE 1303). ® The UE 1303 may send a UWB scheduling message 1314 in response to a verification (or other short-range radio protocol) check, or another trigger. The UE 1303 may request support from the CNE / scheduler 1301 in the IDC report packet of the UWB scheduling message 1314. The UE 1303 may, for example, request the CNE / scheduler 1301 to avoid the only frequency band that the UE 1303 is configured to use (e.g., for UWB signaling). The UWB scheduling message 1314 may provide a set of reserved durations to be avoided by the CNE / scheduler 1301 in RAT scheduling (e.g., start and stop times for UWB transmission), instead of providing detailed UWB scheduling to the CNE / scheduler 1301 via TRP 1302.

[0097] UE 1303 may indicate UWB scheduling parameters for coarse-grained scheduling or fine-grained scheduling of RAT signaling. For coarse-grained scheduling, UWB scheduling message 1314 may indicate high-level information, such as the continuous time period (e.g., an entire ranging round) that can be reserved for UWB transmission. This can be used to disable an entire RAT subframe (or an entire UWB ranging block or an entire UWB ranging time slot) for UWB signaling by CNE / scheduler 1301. UWB scheduling message 1314 may indicate potential UWB channels that can be used, round duration, start time of the next expected round, and / or UWB packet error rate (e.g., over past time intervals). This packet error rate is the packet loss rate attributable to interference. One or more parameters indicated in UWB scheduling message 1314 for coarse-grained scheduling may be indicated by a bitmap. For example, 0s and 1s in specific positions of UWB scheduling message 1314 may indicate whether a corresponding channel will be used for UWB scheduling. As another example, a 0 in a specific position corresponding to a known round duration in UWB scheduling message 1314 can indicate that the corresponding round duration will not be used, while a 1 in a specific position corresponding to the round duration indicates that the corresponding round duration will be used. As another example, one or more parameters can be represented by binary values. For example, channel number 9 can be indicated by binary 1001, and / or the start of the next expected round can be indicated by a binary indication of the time duration in seconds (or minutes).

[0098] For fine-grained scheduling, UWB scheduling message 1314 may indicate lower-level information from which more granular RAT scheduling (e.g., finer time granularity for RAT signaling versus finer time granularity available for UWB signaling) can be determined. For example, fine-grained signaling may be at the UWB slot and RAT symbol resolution level, allowing CNE / scheduler 1301 to determine whether to disable or enable it on a symbol-to-symbol basis. UWB scheduling message 1314 may indicate potential UWB channels that can be used, block duration, block periodicity, round index (which may, for example, change periodically), round duration, minimum number of slots within a round, slot duration, and / or UWB packet error rate, etc. One or more parameters for fine-grained scheduling indicated in UWB scheduling message 1314 may be indicated by a bitmap.

[0099] CNE / scheduler 1301 may request UE 1303 to provide coarse-grained or fine-grained scheduling information. For example, CNE / scheduler 1301 may send a granularity request message 1305 to UE 1303 (e.g., via TRP 1302). For example, granularity request message 1305 may indicate to UE 1303 that CNE / scheduler 1301 wants UE 1303 to send coarse-grained scheduling information in UWB scheduling message 1314 (e.g., when CNE / scheduler 1301 is busy (e.g., due to a congested environment)). As another example, granularity request message 1305 may indicate to UE 1303 that CNE / scheduler 1301 wants UE 1303 to send fine-grained scheduling information in UWB scheduling message 1314 (e.g., when CNE / scheduler 1301 is not busy (e.g., due to a less congested environment around CNE / scheduler 1301, such as a single UE in the neighborhood)). As another example, granularity request message 1305 may indicate to UE 1303 that CNE / scheduler 1301 is willing to determine fine-grained RAT scheduling, and therefore UE 1303 may send fine-grained scheduling information in UWB scheduling message 1314.

[0100] At stage 1320, the radio signaling device 1330 (in this example, CNE / scheduler 1301 (e.g., RAT unit 650)) can use the UWB schedule received from UE 1303 via TRP 1302 to determine a first signal transmission schedule, in this example, a RAT schedule (or in another example, a UWB signal transmission schedule, etc.). RAT unit 650 can generate a new RAT schedule or modify an existing one. CNE / scheduler 1301 can determine the RAT schedule to avoid interference of RAT signals with UWB signals transmitted according to the UWB schedule indicated in UWB scheduling message 1316. For example, the RAT schedule can be used with a specific beam of TRP 1302 to attempt to limit the number of UEs affected by RAT transmission, while accommodating UEs requesting CNE / scheduler 1301 to set the RAT schedule to avoid interference with the requesting UE (here, UE 1303). CNE / scheduler 1301 may send the determined first signaling schedule (here, the RAT schedule) to TRP 1302 in a first signaling schedule message (RAT schedule message 1324 in this example), and TRP 1302 may forward the first signaling schedule to UE 1303 in a RAT schedule message 1326 (e.g., in DCI using PDCCH). UE 1303 may (or may not) modify the UWB schedule based on the received first signaling schedule. If UE 1303 modifies the UWB schedule, UE 1303 may attempt to ensure that UWB transmissions according to the modified UWB schedule do not overlap with signaling transmissions according to the first signaling schedule (e.g., received in RAT schedule message 1326).

[0101] Also refer to Figure 14The signaling and processing flow 1400, used to determine and provide a first signaling schedule (RAT schedule in this example) based on a second signaling schedule (UWB schedule in this example, for IDC), includes the phases shown. Flow 1400 is an example flow and not a limiting one. Flow 1400 can be modified, for example, by adding one or more messages and / or one or more phases and / or splitting one or more messages and / or one or more phases into multiple messages and / or phases. In flow 1400, signaling is passed between one or more radio signaling devices 1405 (including, herein, CNE / scheduler 1401 and one or more TRPs 1402), multiple UEs 1403, and LMF 1404. CNE / scheduler 1401 may be an example of network entity 600. TRPs 1402 may each be an example of TRP 300. UEs 1403 may each be an example of UE 500, where UE 1403 acts as a UWB controller. In the example shown, radio signaling device 1405 includes CNE / scheduler 1401 and TRP 1402. Radio signaling device 1405 may include one or more UEs (e.g., instead of the example shown with CNE / scheduler 1401 and TRP 1402) for example, for SL signaling and / or UWB signaling, and / or one or more other devices. The discussion of procedure 1400 focuses on the example shown with radio signaling device 1405 including CNE / scheduler 1401 and TRP 1402, but procedure 1400 is applicable to other specific implementations, such as where radio signaling device 1405 is one or more UEs.

[0102] At stage 1410, UE 1403 may determine one or more sets of UWB scheduling parameters for the corresponding UWB session with the corresponding controller. One or more of the sets of UWB scheduling parameters may be pre-configured (e.g., determined from one or more previous UWB sessions).

[0103] At stage 1420, the UE may (e.g., via TRP 1402) send a corresponding location information message 1422 to LMF 1404. Each location information message in location information message 1422 may include location information, such as a coarse location estimate of the corresponding UE 1403 (e.g., based on eCID or SPS measurement), and / or one or more location measurements (e.g., SPS measurement, PRS measurement) that can be used by LMF 1404 to determine the corresponding location estimate of the corresponding UE 1403. Sending location information message 1422 may be omitted from procedure 1400, and if sent, it may be sent using LPP and / or another suitable protocol.

[0104] At stage 1430, LMF 1404 may obtain and / or determine the location of UE 1404, and send the UE's location to radio signaling device 1405 in UE location message 1432 (or multiple location messages). For example, LMF 1404 may send one or more UE location messages with the location (i.e., location estimate) of UE 1403 to CNE / scheduler 1401.

[0105] At stage 1440, the radio signaling device 1405 (CNE / scheduler 1401 in this example) determines the parameters of a UWB scheduling request and sends these requested parameters to UE 1403 in a corresponding UWB scheduling message 1442. The requested parameters can be determined by CNE / scheduler 1401 to attempt to avoid interference between UWB sessions of UE 1403. For example, CNE / scheduler 1401 can determine the requested parameters based on the premise that one or more pairs of UE 1403 are close enough to cause interference between different pairs of UE 1403's UWB sessions. The requested parameters can, for example, request that UWB signaling for potentially interfering different UWB sessions be time-division multiplexed (with non-overlapping time windows for UWB transmission) to avoid such interference. The requested parameters can request the granularity of this time-division multiplexing at the RAT subframe level, RAT slot level, or RAT symbol level (e.g., as...). Figure 12 (As shown). CNE / Scheduler 1401 may determine which UWB sessions may interfere with each other based on one or more UE locations provided at stage 1420 and / or one or more UE locations determined at stage 1430. Stage 1440 is optional because radio signaling device 1405 (here, CNE / Scheduler 1401) may not obtain or determine UE locations, and / or may not request or recommend UWB parameters to avoid interference between UWB sessions of UE 1403.

[0106] At stage 1450, UE 1403 may send a UWB schedule for the corresponding UWB session to radio signaling device 1405 (in this example, to TRP 1402) in a UWB scheduling message 1452 (e.g., an IDC report). One or more UWB schedules in the UWB schedule may be determined by one or more UEs in UE 1403 based on one or more UWB schedule requests in one or more UWB schedule messages in UWB scheduling message 1442.

[0107] At stage 1460, in this example, TRP 1402 may relay UWB scheduling to CNE / scheduler 1401 in one or more UWB scheduling messages 1462. TRP 1402 may send UWB scheduling message 1462 for each UWB scheduling message in UWB scheduling message 1452, or may bundle two or more UWB schedulings in a UWB scheduling to each of one or more UWB scheduling messages 1462. For example, if radio signaling device 1405 includes a UE but does not include CNE / scheduler 1401 and TRP 1402, then stage 1460 may be omitted.

[0108] At stage 1470, in this example, CNE / scheduler 1401 may send one or more first signaling schedules (here, one or more RAT schedules) to one or more TRPs in TRP 1402 in one or more first signaling schedule messages. In this example, one or more RAT schedules are sent in one or more RAT schedule messages 1472. The RAT schedules may be determined by CNE / scheduler 1401, for example, based on the UWB schedule received at stage 1460 (e.g., similar to sub-stage 1322 discussed above) to avoid interference between RAT transmissions and UWB transmissions. If the radio signaling device 1405 includes a UE but not CNE / scheduler 1401 and TRP 1402, the transmission of the first signaling schedules between CNE / scheduler 1401 and TRP 1402 at stage 1480 may be omitted.

[0109] At stage 1480, radio signaling device 1405 (TRP 1402 in this example) may send (e.g., relay or forward) a first signaling schedule (RAT schedule in this case) determined to UE 1403 in one or more RAT scheduling messages 1482. The RAT schedule may be different for each TRP in TRP 1402 (or for each radio signaling device in radio signaling device 1405). Each RAT scheduling message in RAT scheduling message 1482 may use the PDCCH from TRP 1402 (or another appropriate protocol and channel for another specific implementation of radio signaling device 1405) as DCI transmission.

[0110] refer to Figure 15 For further reference Figures 1 to 14 Method 1500 for scheduling UWB ranging sessions includes the phases shown. However, method 1500 is merely an example and not a limitation. Method 1500 can be modified, for example, by adding, removing, rearranging, combining, performing one or more phases concurrently, and / or by splitting one or more individual phases into multiple phases.

[0111] At stage 1510, method 1500 includes a first signaling schedule for obtaining a first available signaling time for a first radio signal. For example, at stage 1110, UE 1103 may receive the first signaling schedule (e.g., RAT schedule) in a first signaling schedule message 1112 for radio signaling device 1102. As another example, UE 1103 may learn the first signaling schedule from a first signal 1116. The first radio signal may be the same signal (e.g., a repetition of the same signal, e.g., an instance) or it may be a different signal. Processor 510 (possibly in conjunction with memory 530 and possibly with transceiver 520 (e.g., radio receiver 244 and antenna 246)) may include components for obtaining the first signaling schedule. As another example, processor 510 of UE 1103 may retrieve the first signaling schedule from memory 530 (e.g., in response to a trigger, e.g., receiving a signal from TRP 1102). Processor 510 (possibly in conjunction with memory 530) may include components for obtaining the first signaling schedule. The first wireless signal can be a RAT signal, a UWB signal, etc., and can be transmitted by UE 1103 or by another device (e.g., TRP 1102).

[0112] At stage 1520, method 1500 includes sending a ranging control message from a first UWB device to a second UWB device, the ranging control message instructing a second signal transmission schedule, the second signal transmission schedule including a second available signal transmission time for a second radio signal including a UWB signal, wherein the second available signal transmission time is based on a first available signal transmission time. For example, at stage 1120, UE 1103 may send a UWB schedule to UE 1104 in a second signal transmission schedule message 1124. Processor 510 (possibly combined with memory 530 and transceiver 520 (e.g., radio transmitter 242 and antenna 246)) may include components for transmitting the ranging control message.

[0113] Specific implementations of method 1500 may include one or more of the following features. In an example implementation, the second available signal transmission time is time-division multiplexed with the first available signal transmission time. In another example implementation, method 1500 further includes synchronizing the first UWB device with a radio signaling device from which it obtains a first signal transmission schedule. For example, at stage 1120, UE 1103 may synchronize with radio signaling device 1102 (from which UE 1103 receives or learns the first signal transmission schedule). Processor 510 (possibly combined with memory 530 and transceiver 520 (e.g., radio transmitter 242, radio receiver 244, and antenna 246)) may include components for synchronizing with the radio signaling device. In another example implementation, a ranging control message indicates at least one second signal transmission offset relative to a ranging time slot boundary to avoid overlap between the transmission of any second radio signal in the second radio signal and at least one of the first available signal transmission times. For example, the second signaling schedule message 1124 may indicate an offset 1250 such that the transmission of ranging packets may occur during a duration of 1230 (within time slot 1260) that does not overlap with time slot 1270, even if portions of time slots 1260 and 1270 do overlap. In another example implementation, at least one of the second available signaling transmission times corresponds to an unscheduled reception time in a discontinuous reception mode schedule. In another example implementation, method 1500 further includes determining the second signaling schedule based on UWB latency requirements. For example, at sub-stage 1122, UE 1103 (e.g., UWB unit 550) may determine the UWB schedule based on the latency requirements of the UWB session. Processor 510 (possibly in conjunction with memory 530) may include components for determining the second signaling schedule based on UWB latency requirements. In another example implementation, method 1500 includes determining a second signal transmission schedule based on at least one of the following: signal transmission frame duration, signal transmission subframe duration, signal transmission symbol duration, ranging round duration, or ranging time slot duration. For example, at sub-stage 1122, UE 1103 (e.g., UWB unit 550) may determine the UWB schedule based on at least one of the following: base station signal transmission frame duration, base station signal transmission subframe duration, base station signal transmission symbol duration, ranging round duration, or ranging time slot duration of the signal transmission schedule of radio signaling device 1102 (e.g., TRP, another UE, or UE 1103). Processor 510 (possibly combined with memory 530) may include components for determining the second signal transmission schedule based on at least one of the following: signal transmission frame duration, signal transmission subframe duration, signal transmission symbol duration, ranging round duration, or ranging time slot duration.

[0114] Additionally or alternatively, specific implementations of method 1500 may include one or more of the following features. In an example implementation, method 1500 includes sending at least one parameter of a planned UWB ranging signal transmission schedule from a first UWB device to a radio signaling device, the at least one parameter including: (1) the start of a UWB ranging block and the periodicity of the UWB ranging block; or (2) a first number of ranging rounds within a ranging block and the duration of the ranging rounds; or (3) a second number of ranging time slots within each ranging round and the duration of the ranging time slots; or (4) a ranging round transition pattern; or (5) a ranging round time slot allocation; or (6) any combination of two or more of (1) to (5). For example, UE 1103 may send one or more of these UWB session parameters to CNE 1101 for CNE 1101 to generate a RAT schedule. Processor 510 (possibly combined with memory 530 and transceiver 520 (e.g., wireless transmitter 242 and antenna 246)) may include components for transmitting at least one parameter of the intended UWB ranging signal transmission schedule. In another example implementation, obtaining the first signal transmission schedule includes detecting a pattern of a first wireless signal that satisfies an interference threshold. For example, at sub-state 1118, UE 1103 may measure the first signal 1116 and detect a pattern of the first signal 1116 that exceeds an interference threshold (e.g., a signal strength threshold or a SINR threshold). Processor 510 (possibly combined with memory 530 and transceiver 520 (e.g., wireless receiver 244 and antenna 246)) may include components for detecting a pattern of the first wireless signal that satisfies an interference threshold.

[0115] refer to Figure 16 For further reference Figures 1 to 14 Method 1600 for scheduling the transmission of signals by a wireless signaling device includes the phases shown. However, method 1600 is merely an example and not a limitation. Method 1500 may be modified, for example, by adding, removing, rearranging, combining, performing one or more phases concurrently, and / or by splitting one or more individual phases into multiple phases.

[0116] At stage 1610, method 1600 includes a second signal transmission schedule at a radio signaling device for obtaining a second available signal transmission time for a second radio signal, the second radio signal being a UWB (Ultra-Wideband) signal for a UWB ranging session between a first UWB device and a second UWB device. For example, at stage 1310, radio signaling device 1330 may obtain a UWB signal transmission schedule. For example, a UE or CNE / scheduler 1301 (via TRP 1302) may receive a UWB schedule in a UWB schedule message 1316 indicating the UWB transmission time for a UWB session between UE 1303 and the controller. Processor 610 (possibly in conjunction with memory 630 and transceiver 620 (e.g., radio receiver 444 and antenna 446 and / or wired receiver 454)) may include components for obtaining the second signal transmission schedule. Processor 510 (possibly in conjunction with memory 530, transceiver 520 (e.g., wireless receiver 244 and antenna 246 and / or wired receiver 254)) may include components for obtaining a second signal transmission schedule. As another example, at stage 1450 or at stages 1450, 1460, wireless signaling device 1405 may receive UWB schedules.

[0117] At stage 1620, method 1600 includes transmitting a first signaling schedule from a radio signaling device to a first UWB device and based on a second signaling schedule for a first available signaling time for the first radio signaling. For example, at stage 1320, radio signaling device 1330 may transmit RAT schedule message 1326 to UE 1303 (e.g., CNE / scheduler 1301 may transmit RAT schedule for UE 1303 in RAT schedule message 1324, and TRP 1302 may transmit RAT schedule message 1326 to UE 1303, or UE may transmit message 1326 to UE 1303). Processor 610 (possibly in combination with memory 630 and transceiver 620 (e.g., radio transmitter 442 and antenna 446 and / or wired transmitter 452)) may include components for transmitting the first signaling schedule. The processor 510 (which may be combined with memory 530, transceiver 520 (e.g., wireless transmitter 242 and antenna 246 and / or wired transmitter 252)) may include components for transmitting a first signal transmission schedule.

[0118] Specific implementations of method 1600 may include one or more of the following features. In an example implementation, the first available signal transmission time and the second available signal transmission time are time-division multiplexed. In another example implementation, the UWB ranging session is the first UWB ranging session, and method 1600 further includes: obtaining a third signal transmission schedule for a third available signal transmission time of a third radio signal, the third radio signal being a UWB signal of a second UWB ranging session between a third UWB device and a fourth UWB device, wherein the first UWB device and the third UWB device are within a threshold distance of each other; and transmitting a first signal transmission schedule from a radio signaling device to the third UWB device and based on the second signal transmission schedule and the third signal transmission schedule for the first available signal transmission time of the first radio signal transmission, wherein the first available signal transmission time for the first radio signal transmission is time-division multiplexed with the second and third available signal transmission times.

The corresponding UE in 1403 sends one or more second signal transmission schedules (e.g., RAT schedules), wherein at least one of the second signal transmission schedules is configured such that the first available signal transmission time does not overlap with the second available signal transmission time (UWB signal transmission time) of any of the multiple UWB sessions. Processor 610 (possibly in conjunction with memory 630, transceiver 620 (e.g., radio receiver 444 and antenna 446 and / or wired receiver 454)) may include components for obtaining a third signal transmission schedule.

[0119] Additionally or alternatively, specific implementations of method 1600 may include one or more of the following features. In an example implementation, the first signaling schedule depends on a continuous time period reserved for UWB signaling as indicated in the second signaling schedule. In another example implementation, the first signaling schedule allocates coarse-grained availability for UWB signaling based on one or more parameters of the second signaling schedule, wherein each time duration allocated for UWB signaling is at least a subframe of the first signaling schedule if the first signaling schedule is a cellular signaling schedule or a sidelink signaling schedule, or at least a time slot of the first signaling schedule if the first signaling schedule is a UWB signaling schedule. In another example implementation, the first signaling schedule allocates fine-grained availability for UWB signaling based on one or more parameters of the second signaling schedule, wherein the time duration allocated for UWB signaling is a single symbol of the first signaling schedule. In another example implementation, the first signaling schedule depends on the UWB packet error rate received by the radio signaling device from the first UWB device.

[0224] A wireless communication system is a system in which communication is wirelessly transmitted between wireless communication devices, that is, through the propagation of electromagnetic waves and / or sound waves through the atmosphere rather than through wires or other physical connections. A wireless communication system (also called a wireless communication system or wireless communication network) may not transmit all communication wirelessly, but is configured to transmit at least some communication wirelessly. Furthermore, the term "wireless communication device" or similar terms do not require the device to be functionally exclusive or even primarily used for communication, do not require that communication using the wireless communication device be exclusive or even primarily wireless, and do not require that the device be a mobile device, but rather indicate that the device includes wireless communication capabilities (one-way or two-way), for example, including at least one radio component (each radio component being part of a transmitter, receiver, or transceiver) for wireless communication.

[0225] Specific details are provided in this description to offer a thorough understanding of the example configurations, including specific implementations. However, the configurations can be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail to avoid obscuring these configurations. The description herein provides example configurations and does not limit the scope, applicability, or configuration of the claims. Rather, the preceding description of the configurations provides a description for implementing the described techniques. Various changes can be made to the function and arrangement of the elements.

[0226] As used herein, the terms “processor-readable medium,” “machine-readable medium,” and “computer-readable medium” refer to any medium that participates in providing data that enables a machine to operate in a particular manner. Using a computing platform, various processor-readable media may involve providing instructions / code to a processor for execution, and / or may be used to store and / or carry such instructions / code (e.g., as signals). In many specific implementations, processor-readable media are physical and / or tangible storage media. Such media can take many forms, including but not limited to non-volatile and volatile media. Non-volatile media include, for example, optical discs and / or magnetic disks. Volatile media include, but are not limited to, dynamic memory.

[0227] Having described several example configurations, various modifications, alternative constructions, and equivalents can be used. For example, the above elements can be components of a larger system, where other rules may take precedence over or otherwise modify the application of this disclosure. Furthermore, several operations may be performed before, during, or after considering the above elements. Accordingly, the above description does not limit the scope of the claims.

[0228] Unless otherwise indicated, the terms "about" and / or "approximately" as used herein when referring to measurable values ​​(such as quantities, durations of time, etc.) cover variations of ±20%, ±10%, ±5%, or ±0.1% from the specified value, as appropriate in the context of the systems, devices, circuits, methods, and other specific embodiments described herein. Similarly, unless otherwise indicated, the term "substantially" as used herein when referring to measurable values ​​(such as quantities, durations of time, physical properties (such as frequencies), etc.) also covers variations of ±20%, ±10%, ±5%, or ±0.1% from the specified value, as appropriate in the context of the systems, devices, circuits, methods, and other specific embodiments described herein.

[0229] A statement that a value exceeds (or is greater than or higher than) a first threshold is equivalent to a statement that a value meets or exceeds a second threshold slightly greater than the first threshold. For example, in the resolution of the computing system, the second threshold is one value higher than the first threshold. A statement that a value is less than the first threshold (or within or below the first threshold) is equivalent to a statement that a value is less than or equal to a second threshold slightly lower than the first threshold. For example, in the resolution of the computing system, the second threshold is one value lower than the first threshold.
