Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for narrowband-assisted ultra-wideband message sequences. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0040] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0041] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0042] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0043] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network as well as other examples. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), a user equipment (UE) 120 or a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base station 110 is an entity that communicates with the UE 120. The base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). In addition, although the base station 110 Figure 1 10 is shown as an integral unit, but aspects of the present disclosure are not limited thereto. In some other aspects, the functionality of the base station 110 can be decomposed according to an open radio access network (O-RAN) architecture, etc. In such aspects, one or more of a centralized unit (CU), a distributed unit (DU), a radio unit (RU), etc. can individually or collectively perform the functions of the base station 110 described herein.

[0044] More specifically, in some aspects, the term "base station" (e.g., base station 110), "network node" or "network entity" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node and / or one or more components thereof. For example, in some aspects, a "base station", "network node" or "network entity" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC) or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station", "network node" or "network entity" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with base station 110). In some aspects, the term "base station", "network node" or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographical location or in different geographical locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station", "network node" or "network entity" may refer to any one or more of these different devices. In some aspects, the terms "base station", "network node" or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the terms "base station", "network node" or "network entity" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0045] Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used. A base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A base station 110 used for a macro cell may be referred to as a macro base station. A base station 110 used for a pico cell may be referred to as a pico base station. A base station 110 used for a femto cell may be referred to as a femto base station or a home base station. In Figure 1In the example shown in , BS 110a may be a macro base station for macro cell 102a, BS 110b may be a pico base station for pico cell 102b, and BS 110c may be a femto base station for femto cell 102c. A base station may support one or more (eg, three) cells.

[0046] In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move according to the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 can be interconnected with each other and / or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0047] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station 110 or a UE 120) and transmit transmissions of data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , BS 110d (eg, a relay base station) can communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 that relays communication may be referred to as a relay station, relay base station, relay, or the like.

[0048] The wireless network 100 may be a heterogeneous network that includes different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0049] The network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for the base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may also communicate directly with each other or indirectly via wireless or wired backhaul communication links.

[0050] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device and / or any other suitable device configured to communicate via a wireless medium.

[0051] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0052] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0053] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more side link channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0054] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0055] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0056] In view of the above examples, unless otherwise explicitly stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term can be broadly referred to as frequencies that can be lower than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that the term "millimeter wave" or the like, if used herein, can be broadly referred to as frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0057] In some aspects, a first wireless communication device as described herein may correspond to and / or may be associated with UE 120. In some aspects, the first wireless communication device may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 of the first wireless communication device may send a time and / or frequency synchronization message to a second wireless communication device using a first RF technology, wherein the time and / or frequency synchronization message is used to obtain synchronization information for the second RF technology; send a first set of ranging measurement signals associated with the second RF technology to the second wireless communication device; and receive a second set of ranging measurement signals associated with the second RF technology from the second wireless communication device, wherein the time and / or frequency synchronization message is sent in a first set of one or more ranging time slots, wherein at least a first ranging measurement signal in the first set of one or more ranging time slots is sent in a first ranging time slot after the first set of one or more ranging time slots, wherein at least a first ranging measurement signal in the second set of ranging measurement signals is received in the first ranging time slot, wherein at least a second ranging measurement signal in the first set of ranging measurement signals is sent in a second ranging time slot after the first ranging time slot, and wherein at least a second ranging measurement signal in the second set of ranging measurement signals is received in the second ranging time slot.

[0058] In some other aspects, the communication manager 140 of the first wireless device may send a time and / or frequency synchronization message to a second wireless communication device using a first RF technology, wherein the time and / or frequency synchronization message is used to obtain synchronization information for the second RF technology; send a first set of ranging measurement signals associated with the second RF technology to the second wireless communication device; and receive a second set of ranging measurement signals associated with the second RF technology from the second wireless communication device, wherein the time and / or frequency synchronization message is sent in a first set of one or more ranging slots, wherein the first set of ranging measurement signals is sent in a first ranging slot after the first set of one or more ranging slots, and wherein the second set of ranging measurement signals is received in a second ranging slot after the first ranging slot.

[0059] In some other aspects, the communication manager 140 of the first wireless communication device may send a time and / or frequency synchronization message to a second wireless communication device using a first RF technology, wherein the time and / or frequency synchronization message is used to obtain synchronization information for the second RF technology; send a first set of ranging measurement signals associated with the second RF technology to the second wireless communication device; and receive a second set of ranging measurement signals associated with the second RF technology from the second wireless communication device, wherein the time and / or frequency synchronization message is sent in a first set of one or more ranging time slots, wherein each ranging measurement signal in the first set of ranging measurement signals is sent in a corresponding ranging time slot after the first set of one or more ranging time slots, and wherein each ranging measurement signal in the second set of ranging measurement signals is received in a corresponding ranging time slot after the sending of the first set of ranging measurement signals. Additionally or alternatively, the communication manager 140 of the first wireless communication device may perform one or more other operations described herein.

[0060] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different than described.

[0061] Figure 2 2 is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0062] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may further process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0063] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110, and a set of received signals (e.g., R received signals) may be provided to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples.

The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0065] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, among other examples. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2One or more antenna elements of one or more components in.

[0066] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, reference Figures 5 to 19 )Aspects of any of the methods described herein.

[0067] At the base station 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232 shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 5 to 19 )Aspects of any of the methods described herein.

[0068] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the UE 120 may perform one or more techniques associated with the narrowband-assisted ultra-wideband message sequence, as described in more detail elsewhere herein. In some aspects, the wireless communication device described herein is a UE 120, is included in a UE 120, or includes Figure 2 One or more components of UE 120 shown in FIG.

In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Fig.12 The process 1200 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0075] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0076] Figure 3 3 is a diagram illustrating an example 300 of RF components of a UE 120 according to the present disclosure. Although described in the context of a UE 120 for convenience, Figure 3 However, the aspects of the present disclosure are not limited thereto. In other aspects, in combination with Figure 3 Certain features and components of the described UE 120 may be incorporated into another wireless communication device (eg, a UWB device) without departing from the scope of the present disclosure.

[0077] In some cases, UE 120 may be equipped with multiple transceivers capable of operating various RF technologies. Figure 2In addition to the transceiver components described (which in some cases can be used to communicate over the wireless network 100, as described), the UE 120 can also be equipped with additional transceivers or similar components, such as transceivers associated with short-range wireless communication technologies. Short-range wireless communication implements wireless communication within a relatively short distance (e.g., within 30 meters). The Bluetooth protocol is an example of a wireless technology standard for exchanging data over a short distance using short-wavelength ultra-high frequency (UHF) radio waves from 2.4 gigahertz (GHz) to 2.485GHz. The Bluetooth low energy (BLE) protocol is used to communicate with devices operating at low energy consumption. Various other short-range wireless communication technologies can operate at similar wavelengths, such as wireless local area network (WLAN) technology, Zigbee, and ultra-wideband (UWB) technology, which are described in more detail below. In some aspects, certain technologies such as Bluetooth, BLE, WLAN, and Zigbee can operate using relatively narrow frequency bands compared to UWB technology, and therefore can be collectively referred to as narrowband (NB) technology.

[0078] like Figure 3 As shown in FIG. 1 , in some cases, UE 120 may include components for communicating using one or more short-range wireless communication technologies. For example, UE 120 may include UWB components (such as Figure 3 ) or related components. In some cases, the UWB transceiver 305 may include various components that implement UWB communications, such as a UWB signal generator / processor 310 and / or a UWB antenna or antenna array 315. As shown, the UWB signal generator / processor 310 and the UWB antenna or antenna array 315 may communicate with each other (e.g., via one or more buses and / or one or more other components).

[0079] One or more of the UWB transceiver 305, the UWB signal generator / processor 310, and the UWB antenna or antenna array 315 can implement UWB connectivity. UWB connectivity is a short-range wireless communication protocol that operates at very high frequencies compared to other short-range wireless communication technologies (e.g., Bluetooth, WLAN, Zigbee, etc.), and uses a relatively wide frequency band (e.g., 500 MHz or greater) compared to other short-range wireless communication technologies, which makes UWB useful for high-resolution positioning and localization purposes. In some cases, UWB technology can be used for location discovery, device ranging, etc. In some cases, a UWB transmitter (e.g., a UWB transceiver 305) can send many pulses across a wide spectrum of frequencies, and a corresponding UWB receiver (e.g., a UWB transceiver 305 located at another UWB-enabled device) can convert the pulses into data by listening to the familiar pulse sequence transmitted by the transmitter.

[0080] When multiple UWB devices are close to each other (e.g., when two UEs 120 including UWB components such as UWB transceivers 305 are close to each other), the two UWB devices may begin ranging or measuring the distance between each other. In such cases, the first UWB device (e.g., the UWB that first sends a UWB communication (sometimes referred to as a ranging measurement signal and / or a UWB measurement signal)) may be referred to as an initiator, and the second UWB device may be referred to as a responder. In some cases, measuring the distance between two UWB devices may be referred to as two-way ranging (TWR) because the measurement relies on two-way communication between the two UWB devices. More specifically, in TWR, the initiator and responder may measure the distance between each other using a time-of-flight (TOF) measurement, such as by multiplying the round-trip time of the signal by the speed of light and dividing by two. In some aspects, a UWB device may be able to determine the relative position of a peer device with a line of sight of up to 200 meters or a similar distance. In some aspects, the UWB device may be able to perform two-dimensional or three-dimensional positioning by additionally measuring the distance between the UWB device and a fixed beacon or anchor point and then using triangulation. In some cases, "TWR" may refer to a single-sided TWR or a double-sided TWR. "Single-sided TWR" may refer to a TWR based on two messages or message sets sent between an initiator and a responder (e.g., a polling message or a polling message set transmitted from the initiator to the responder, and a reply message or a reply message set transmitted from the responder to the initiator), while "double-sided TWR" may refer to a TWR based on three or more messages or message sets sent between an initiator and a responder (e.g., the above-mentioned polling and reply messages in addition to the final message or final message set transmitted from the initiator to the responder, and optionally, a report message or a report message set transmitted from the responder to the initiator).

[0081] Return to Figure 3 , UE 120 may include additional transceivers or components, such as additional transceivers associated with different short-range wireless communication protocols. For example, UE 120 may include NB components (such as Figure 3) or related components. In some cases, the NB transceiver 320 may include various components that implement NB connectivity, such as a NB signal generator / processor 325 and / or a NB antenna or antenna array 330. As shown, the NB signal generator / processor 325 and the NB antenna or antenna array 330 may communicate with each other. In some cases, the NB transceiver 320 and / or other NB components of the UE 120 may be associated with one or more of Bluetooth connectivity, BLE connectivity, WLAN connectivity, Zigbee connectivity, etc., which may use relatively narrow frequency bands compared to UWB connectivity and / or may operate in a relatively low frequency range compared to UWB connectivity.

[0082] In some cases, the UWB components (e.g., UWB transceiver 305) and / or the NB components (e.g., NB transceiver 320) can communicate with each other or otherwise coexist with each other. For example, in some cases, the UWB transceiver 305 and / or the NB transceiver 320 can be connected to the processor 335. The processor 335 can control certain functions of the UWB transceiver 305 and / or the NB transceiver 320, including in some cases causing the UWB transceiver 305 and / or the NB transceiver 320 to operate in conjunction with each other. For example, in some cases, the processor 335 can control the UWB transceiver 305 and / or the NB transceiver 320 for the purpose of performing NB Assisted (NBA) UWB (NBA-UWB) technology (such as the NBA-UWB technology described below).

[0083] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0084] Figure 4 is a diagram illustrating an example 400 of a UWB packet structure and a multi-millisecond NB-assisted UWB packet structure according to the present disclosure.

[0085] As combined Figure 3 As described, in some cases, UE 120 or other UWB devices may send UWB packets between each other for the purpose of estimating the range (or distance) between devices, or for other purposes such as estimating the angular direction in which stations appear relative to each other. UE 120 or other UWB devices may also send UWB packets to exchange payload data between each other.

[0086] Like many other wireless communication systems (eg, WLAN, Bluetooth, or cellular services), UWB transmissions adhere to certain physical layer (PHY) frame formats or packet formats (the terms "packet" and "frame" are used interchangeably herein). Figure 4An example packet format for use in UWB transmissions is illustrated. More specifically, a UWB device may use a no data (ND) packet structure (as shown by reference numeral 405), an NBA-UWB packet structure (as shown by reference numeral 410), an NBA multi-millisecond UWB packet structure (as shown by reference numeral 415), or other similar packet structures.

[0087] The ND packet structure may include a preamble 420, a frame start delimiter (SFD) 425, and / or a scrambled timestamp sequence (STS) 430. In some aspects, the ND packet structure may be used to synchronize time and / or frequency between two UWB devices. For example, a first UWB device (e.g., an initiator) may send an ND packet, and another UWB device (e.g., a responder) may listen to the preamble 420. Once the preamble 420 is detected, the responder may listen to the SFD 425. The responder may use the SFD 425 to obtain frame timing. For example, a UWB packet may be sent by the initiator UWB at time 0, and thus the responder UWB device may timestamp the arrival of the UWB packet (e.g., the arrival of the preamble 420 and / or the SFD 425) to time 0. In addition, the responder may listen to the STS 430, which may be used in some cases for purposes such as channel estimation and / or timestamp verification for range estimation based on secure TOF. In some cases, preamble 420 may alternatively be referred to as a ranging preamble or a synchronization component (SYNC), and / or preamble 420 and SFD 425 (and optionally STS 430, if equipped) may be collectively referred to as a synchronization header (SHR). By receiving preamble 420, SFD 425, or / and STS 430, a responding UWB device may synchronize time and / or frequency with an initiating UWB device and thus receive a UWB transmission (e.g., preamble 420) for the purpose of TWR or for other purposes.

[0088] In other cases, one or more UWB devices may be synchronized based on another RF technology, such as NB technology. In some cases, this may be referred to as NBA-UWB. Reference numeral 410 indicates an example of an NBA-UWB packet structure. In this example, NB packet 435 provides time and / or frequency synchronization information for a UWB packet, such as for a UWB measurement signal 440 (e.g., a UWB preamble or similar measurement signal). More specifically, a NB component associated with an initiator device (e.g., in conjunction with Figure 3 The NB transceiver 320 described above may send a NB packet 435, which in some cases may be used to provide initial time and / or frequency synchronization for subsequent UWB transmissions. Figure 4As shown in , in some cases, the initiator may send a NB packet 435 before time 0, and then subsequently send a UWB measurement signal 440 at time 0 (which in some cases may be just a ranging preamble (e.g., preamble 420) without SFD 425 and / or STS 430). The responder UWB device may receive the NB packet 435 and synchronize time and / or frequency accordingly to correctly receive the UWB measurement signal 440 at time 0. Time and frequency synchronization may be further achieved using UWB communication.

[0089] In other cases, multiple UWB transmissions may be synchronized and / or scheduled based on another RF technology, such as NB technology. For example, in some cases, NB packet 435 may synchronize and / or schedule multiple UWB transmissions that span more than one millisecond, and may therefore be referred to as NBA multi-millisecond UWB. Reference numeral 415 indicates an example of an NBA multi-millisecond UWB packet structure. In this example, NB packet 435 provides time and / or frequency synchronization information for multiple UWB packets, such as multiple UWB measurement signal 440 transmissions. More specifically, a NB component associated with an initiator device (e.g., in conjunction with Figure 3 4. The NB transceiver 320 described above may send a NB packet 435, which in some cases may include time and / or frequency synchronization information for multiple subsequent UWB transmissions. In other words, the NB component shares a clock source with the UWB component. In some cases, this initial synchronization process (e.g., establishing and providing initial timing and frequency synchronization for UWB measurements) may be referred to as Phase I or Phase 1.

[0090] like Figure 4As shown in , the initiator may send a NB packet 435 before time 0, and then subsequently send a first UWB measurement signal 440 at time 0 (which in some cases may be just the preamble 420 without the SFD 425 and / or STS 430). The initiator UWB may send additional packets (e.g., UWB measurement signals 440) separated by a given time period so that the UWB measurement may be performed over a longer duration (e.g., multiple milliseconds) than the structure described in conjunction with reference numerals 405 and 410. In some cases, each UWB packet and / or transmission may be referred to as a segment. Multiple one-millisecond segments may enable combining for purposes such as link budget gain. The responder UWB device may receive the NB packet 435 and synchronize time and / or frequency accordingly so as to correctly receive multiple UWB measurement signals 440 at time 0, time 1, time 2, etc. In some cases, the UWB measurement signal 440 may be measured for the purpose of a ranging process. Measuring the UWB segments using UWB connectivity may be referred to as Phase II or Phase 2. In some cases, the responder UWB device may send a measurement report to the initiator UWB device indicating the measurements performed during Phase II. The measurement report may be sent using the same RF connectivity as Phase I (e.g., the same NB connectivity used to send NB packet 435). In some cases, sending the measurement report may be referred to as Phase III or Phase 3.

[0091] In some cases, the NB technology used to send the NB packet 435 can be associated with an unlicensed national information infrastructure (UNII) radio band, such as a UNII-3 band (e.g., a band associated with a frequency range of 5.725 GHz to 5.850 GHz and a bandwidth of 125 MHz) or another UNII band (e.g., UNII-5 (5.925 GHz to 6.425 GHz frequency range and 500 MHz bandwidth), UNII-6 (6.425 GHz to 6.525 GHz frequency range and 100 MHz bandwidth), UNII-7 (6.525 GHz to 6.875 GHz frequency range and 350 MHz bandwidth), and / or UNII-8 (6.875 GHz to 7.125 GHz frequency range and 250 MHz bandwidth). Additionally or alternatively, the NB technology used to send the NB packet 435 can be associated with WLAN, Bluetooth, BLE, and / or offset quadrature phase shift keying (0-QPSK) technology such as Zigbee.

[0092] In some aspects, utilizing NB technology for time and / or frequency synchronization purposes (e.g., utilizing one of the NBA-UWB packet structures described above) can yield certain benefits over the UWB packet structure, such as enabling frequency hopping and / or enabling the transmission of an initial packet (e.g., NB packet 435) using a higher transmit power (e.g., 14 dBm) than UWB, which can be used for purposes such as range extension. In addition, multiple one millisecond segments can enable combining for purposes such as link budget gain, while using NB technology for clock synchronization purposes can reduce overhead on the UWB spectrum, thereby increasing transmission opportunities and improving ranging capabilities. However, NBA-UWB technology has not been adapted for the purposes of TWR, and therefore their application is limited.

[0093] Some techniques and apparatus described herein enable the use of NBA-UWB technology for TWR purposes, thereby enabling the transmission of initial synchronization packets using higher transmission power compared to UWB, enabling the combination of multiple one-millisecond segments for the purpose of link budget gain in TWR, and reducing the overhead on the UWB spectrum in TWR, thereby increasing transmission opportunities and improving TWR capabilities. Figures 5 to 11 Aspects of using NBA-UWB technology for the purpose of TWR are described.

[0094] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different than described.

[0095] Figures 5 to 11 is a diagram illustrating an example of an NBA-UWB sequence for a one-sided TWR according to the present disclosure.

[0096] first, Figure 5 An example 500 of sequential transmission for the purpose of single-sided TWR is shown. In this example, a message or packet indicated as "NB" can be associated with a first RF technology, which can be NB technology (e.g., one of Bluetooth, BLE, WLAN, or 0-QPSK technology such as Zigbee), and a message or packet indicated as "UWB measurement signal" can be associated with a second RF technology, which can be UWB technology. More specifically, the message or packet indicated as "UWB measurement signal" can be a ranging measurement signal and / or a UWB measurement signal. Additionally or alternatively, the message or packet indicated as "NB" can be transmitted via one of UNII-3, UNII-5, UNII-6, UNII-7, or UNII-8.

[0097] exist Figure 5In the example shown in , there is one measurement sequence (e.g., initiator (Tx) to responder (Rx) transmission), followed by another measurement sequence (e.g., responder (Tx) to initiator (Rx) transmission). In such aspects, and as indicated by reference numeral 505, in a first sequence (e.g., initiator to responder sequence), the initiator may transmit a time and / or frequency synchronization message 510 (e.g., a message using a first RF technology (such as NB technology)) that provides time and / or frequency synchronization information for multi-millisecond UWB preamble transmissions, etc., such as a plurality of ranging measurement signals 515 (e.g., ranging preamble messages). The initiator may then transmit a plurality of ranging measurement signals 515 at regular intervals (e.g., one per millisecond, as shown at time 0 to M-1) based at least in part on the synchronization information.

[0098] As indicated by reference numeral 520, in a second sequence (e.g., a responder to initiator sequence), the responder may optionally send a response message 525 (e.g., a message using a first RF technology, such as a NB technology). The response message 525 may provide time and / or frequency synchronization information for the initiator. However, in some other aspects, the responder may synchronize itself with the timing and frequency of the initiator (e.g., the responder's NB and UWB time are associated with the time and / or frequency synchronization message 510 (e.g., NB timing) and / or ranging measurement signal 515 (e.g., UWB timing) received from the initiator), and thus the responder may omit the time and frequency synchronization message in the response message 525. In other words, in some aspects, the responder's clock may be corrected based on the initiator's clock. Additionally or alternatively, the response message 525 may include a measurement report (e.g., a measurement report associated with measuring the ranging measurement signal 515), while in some other aspects, the measurement report may be included in a separate NB message, as described below in conjunction with Figure 6 525. Additionally or alternatively, the response message 525 may include information associated with a two-way handshake between the initiator and the responder. Additionally or alternatively, the response message 525 may include information associated with frequency correction (e.g., the response message 525 may indicate that the frequency correction is performed at the responder due to hardware limitations or otherwise). In some other aspects, the response message 525 may be omitted entirely.

[0099] As further shown by reference numeral 520, the responder may transmit multiple ranging measurement signals 530 at regular intervals (e.g., one per millisecond, as shown at times M+1 to 2M-1) based at least in part on synchronization information received from the time and / or frequency synchronization message 510 and / or based at least in part on timing information indicated by the ranging measurement signal 515 transmitted by the initiator. In some aspects, to accommodate different implementations, flexible intervals may be left between NB transmissions (e.g., time and / or frequency synchronization messages 510 and / or response messages 525) and UWB transmissions (e.g., ranging measurement signals 515, 530). Based at least in part on the transmission and reception of the ranging measurement signals 515, 530, the wireless communication device (e.g., the initiator) may perform one-sided TWR, etc.

[0100] In some aspects, such as Figure 5 As shown in , sequential transmission of ranging preamble sets may be undesirable due to the latency associated with bidirectional transmission of multiple segments (e.g., due to the latency associated with transmitting the entire first sequence before receiving the second sequence). Figure 5 In the example shown in , each wireless communication device (eg, initiator and responder) waits to receive all UWB segments before replying. Thus, in some aspects, NB messages and / or UWB messages may be interleaved to avoid such delays.

[0101] More specifically, Figure 6An example 600 is shown in which NB messages and / or UWB messages are interleaved with each other. More specifically, as indicated by reference numeral 605, the initiator and responder may exchange NB synchronization or similar messages prior to UWB transmission. For example, the initiator may send a time and / or frequency synchronization message 510 using NB technology, and optionally, the responder may send a response message 525 using NB technology. The initiator and responder may then exchange ranging measurement signals 515, 530, or similar UWB messages in an interleaved manner. More specifically, as indicated by reference numerals 610 and 615, the initiator and responder may exchange a first pair of UWB segments (e.g., a first ranging measurement signal 515 sent by the initiator and a first ranging measurement signal 530 sent by the responder) before exchanging a second pair of UWB segments (e.g., a second ranging measurement signal 515 sent by the initiator and a second ranging measurement signal 530 sent by the responder). In some aspects, and as indicated by reference numeral 620, the responder may additionally send a report message 625, which may include a measurement report associated with the TWR procedure. In some aspects, the measurement report may be sent using the same connectivity (e.g., NB connectivity) as the time and / or frequency synchronization message 510, and / or may be transmitted after the initiator and responder have exchanged interleaved ranging measurement signals 515, 530. In some aspects, in response to securely receiving the measurement report, the initiator may send an acknowledgment (ACK) message 630 using the same connectivity (e.g., NB connectivity) as the measurement report. In such aspects, if the NB report delivery has been successful, the ACK message 630 may advantageously free up memory for the measurement report until the next ranging block.

[0102] In some aspects, once the initiator and responder have synchronized time and / or frequency in a ranging round as described above, future synchronization (e.g., future transmissions of the time and / or frequency synchronization message 510) may be omitted. In some aspects, the need for transmission of the time and / or frequency synchronization message 510 in a subsequent TWR round may be negotiated by the initiator and responder. Additionally or alternatively, in some aspects, if the next TWR round is close in time, the time and / or frequency may not change significantly between the two TWR rounds and thus additional synchronization may be omitted. In some aspects, the time and frequency may be further refined during the UWB segment of the previous TWR round (e.g., using messages transmitted via the ranging measurement signals 515, 530) and may then be used for a subsequent TWR round without another transmission of the time and / or frequency synchronization message 510.

[0103] In some aspects, one or more messages sent by the responder (e.g., one or more of the response message 525 and / or the ranging measurement signal 530) can be used to signal an early termination request to the initiator. In some aspects, the responder can determine the number of UWB segments to be received (e.g., the number of ranging measurement signals 515), and can signal the early termination of the TWR process based at least in part on the number of UWB segments, etc. For example, in some aspects, the responder can measure the received power of the NB message, and based at least in part on the difference between the received power and / or the NB link budget and the UWB link budget, the responder can calculate how many UWB segments are required for a particular measurement. In such aspects, the responder can signal the number of required UWB segments in the NB response message (e.g., the response message 525). In some other aspects, based at least in part on determining that the UWB received power exceeds a threshold after coherent combining of the UWB segments, the responder can signal the early termination to the initiator. In such aspects, the early termination may be indicated to the initiator via a UWB measurement signal from the responder (eg, via one or more ranging measurement signals 530). Additionally, a special sequence design may be used for UWB segments to communicate early termination.

[0104] Figure 7 An example 700 of a UWB ranging session 705 in accordance with aspects of the present disclosure is shown. In some aspects, NB technology (such as BLE) can be used for discovery purposes and to establish the UWB ranging session 705 shown in example 700. This can include selecting a UWB channel to use, configuring ranging slots, rounds, and block durations using a NB connection (e.g., BLE connectivity), etc. More specifically, in some aspects, the UWB ranging session 705 can include one or more ranging blocks 710, wherein each ranging block 710 includes one or more ranging rounds 715, and wherein each ranging round 715 includes one or more ranging slots 720. In some aspects, the UWB ranging session 705 can be configured to include one UWB measurement per ranging round 715, and / or one ranging round 715 per ranging block 710. In addition, the ranging blocks 710, ranging rounds 715, and / or ranging slots 720 durations may be configured such that each ranging slot 720 is long enough to complete one UWB message, and such that the number of ranging slots 720 per ranging round 715 is large enough to complete one ranging measurement. In some aspects, the ranging slots 720 may be configured to have sufficient length to include one or more NB messages (e.g., time and / or frequency synchronization messages 510, response messages 525, report messages 625, ACK messages 630, or similar NB messages) and / or one or more UWB measurement signals (e.g., ranging measurement signals 515, ranging measurement signals 530, or similar UWB measurement signals), which are described below in conjunction with Figures 8 to 11Describe in more detail.

[0105] In some aspects, NB connectivity can be used to synchronize the start time of the ranging session 705. For example, NB connectivity or a component associated with NB connectivity can pass a time parameter (sometimes referred to as UWB_Time_T0, as shown at reference numeral 725) to UWB connectivity or a component associated with UWB connectivity to mark the start of the ranging session 705. In some aspects, the duration of each ranging block 710 can determine the frequency of ranging measurements. For example, in some aspects, a single-sided TWR measurement can be completed per ranging block 710, and thus a shorter duration ranging block 710 can result in a more frequent TWR measurement, while a longer duration ranging block 710 can result in a less frequent TWR measurement. In addition, in some aspects, round hopping can be configured so that the index of the ranging round 715 changes from one ranging block 710 to the next ranging block 710. For example, when round hopping is enabled, the round index can be selected in each ranging block 710 based at least in part on a specified round hopping function.

[0106] In some aspects, ranging session 705 can be based at least in part on a combination of Figure 5 to Figure 6 First, as described by Figure 8 As shown in example 800, and with respect to combining Figure 5 The sequential transmission of UWB segments described above may assign one ranging slot to each sequence of NB messages and corresponding UWB segments. More specifically, a first sequence (e.g., a time and / or frequency synchronization message 510 and a ranging measurement signal 515 sent by an initiator) may be assigned to a first ranging slot (e.g., ranging slot 0), and a second sequence (e.g., a response message 525 (if used) and a ranging measurement signal 530 sent by a responder) may be assigned to a second ranging slot (e.g., ranging slot 1).

[0107] Alternatively, if Fig. 9 As shown in example 900, and again with respect to the combination Figure 5The sequential transmission of UWB segments described above, each NB transmission may be assigned one or more ranging slots, and each set of UWB segments may be assigned one ranging slot. More specifically, a first NB message (e.g., a time and / or frequency synchronization message 510 transmitted by an initiator) may be assigned a first set of one or more ranging slots (as shown in ranging slots 0 to N-1), a first set of UWB segments (e.g., a ranging measurement signal 515 transmitted by an initiator) may be assigned to a first ranging slot (e.g., ranging slot N), a second NB message (e.g., a response message 525 transmitted by a responder, if used) may be assigned a second set of one or more ranging slots (as shown in ranging slots N+1 to 2N), and a second set of UWB segments (e.g., a ranging measurement signal 530 transmitted by a responder) may be assigned to a second ranging slot (e.g., ranging slot 2N+1).

[0108] Alternatively, if Fig.10 Example 1000 is shown, and again with respect to the combination Figure 5 The sequential transmission of UWB segments described above, each NB transmission may be assigned one or more ranging slots, and each UWB segment may be assigned one ranging slot. More specifically, a first NB message (e.g., a time and / or frequency synchronization message 510 transmitted by an initiator) may be assigned a first set of one or more ranging slots (e.g., ranging slots 0 to N-1), a first UWB segment transmitted by an initiator (e.g., a first ranging measurement signal 515 transmitted by an initiator) may be assigned to a first ranging slot (e.g., ranging slot N), a second UWB segment transmitted by an initiator (e.g., a second ranging measurement signal 515 transmitted by an initiator) may be assigned to a second ranging slot (e.g., ranging slot N+1), and so on for the remaining UWB segments transmitted by the initiator (e.g., in the depicted example, up to ranging slot N+M-1). In addition, a second NB message (e.g., response message 525 sent by the responder) may be assigned a second set of one or more ranging slots (as shown in ranging slots N+M to 2N+M-1), a first UWB segment sent by the responder (e.g., a first ranging measurement signal 530 sent by the responder) may be assigned to the ranging slot after the second NB message (e.g., ranging slot 2N+M), and so on for the remaining UWB segments sent by the responder (e.g., in the depicted example, up to ranging slot 2N+2M-1).

[0109] As Fig.11 Example 1100 is shown, and regarding the combination Figure 6In some aspects of the interleaved transmission of UWB segments described, each NB transmission may be assigned one or more ranging slots, and each pair of interleaved UWB segments may be assigned one ranging slot. More specifically, a first NB message (e.g., a time and / or frequency synchronization message 510 sent by an initiator) and, if used, a second NB message (e.g., a response message 525 sent by a responder) may be assigned a first set of one or more ranging slots (e.g., ranging slots 0 to N-1). In addition, the interleaved first pair of UWB segments sent by the initiator and the responder (e.g., the first ranging measurement signal 515 sent by the initiator and the first ranging measurement signal 530 sent by the responder) can be assigned to a first ranging slot (e.g., ranging slot N), the interleaved second pair of UWB segments sent by the initiator and the responder (e.g., the second ranging measurement signal 515 sent by the initiator and the second ranging measurement signal 530 sent by the responder) can be assigned to a second ranging slot (e.g., ranging slot N+1), and so on for the remaining pairs of UWB segments. In addition, any additional NB messages (e.g., the report message 625 sent by the responder and / or the ACK message 630 sent by the initiator) can be assigned a second set of one or more ranging slots (as shown in ranging slots N+2 to 2N+1).

[0110] In some aspects, the NB messages described above may require more than one ranging slot (e.g., each NB message duration may be longer than one ranging slot) and thus may be assigned a set of multiple ranging slots, as described. Additionally or alternatively, in some aspects, there may be a configurable offset between NB messages and UWB segments based at least in part on a negotiation in a specific implementation. Further, in some aspects, one or more of the NB messages may be sent outside of the ranging session 705. More specifically, in some aspects, a NB message sent outside of the ranging session 705 (e.g., a NB message sent prior to the ranging session 705) may pass a time parameter (e.g., UWB_Time_T0, as shown at reference numeral 725) to the UWB connectivity or a component associated with the UWB connectivity to mark the start of the ranging session 705. In other words, in some aspects, the NB setup may be completed prior to implementing the ranging slot structure for the UWB messages. This may be because fitting NB transmissions into a fixed number of ranging slots may be challenging, particularly for implementations where a fast turnaround time between NB messages and UWB segments is preferred.

[0111] As indicated above, Figures 5 to 11 are provided as examples. Other examples can be found in the Figures 5 to 11 Different than described.

[0112] Fig.12 is a diagram illustrating an example process 1200 performed, for example, by a first wireless communication device in accordance with the present disclosure. The example process 1200 is an example in which a first wireless communication device (eg, UE 120) performs operations associated with a narrowband-assisted ultra-wideband message sequence.

[0113] like Fig.12 As shown in , in some aspects, process 1200 may include sending a time and / or frequency synchronization message to a second wireless communication device using a first RF technology, wherein the time and / or frequency synchronization message is used to obtain synchronization information for the second RF technology (block 1210). For example, a first wireless communication device (e.g., using Fig.16 The communication manager 1608, the sending component 1604 and / or the NB component 1614 depicted in the figure can perform the operations of box 1210, as described above.

[0114] like Fig.12 As further shown in FIG. 1 , in some aspects, process 1200 may include sending a first set of ranging measurement signals associated with a second RF technology to a second wireless communication device (block 1220). For example, a first wireless communication device (e.g., using Fig.16 The communication manager 1608, TWR component 1610, and / or UWB component 1612 depicted in FIG. 16A may perform the operations of block 1220 as described above.

[0115] like Fig.12 As further shown in FIG. 1 , in some aspects, process 1200 may include: receiving a second set of ranging measurement signals associated with a second RF technology from a second wireless communication device, wherein the time and / or frequency synchronization message is sent in a first set of one or more ranging slots, wherein at least a first ranging measurement signal in the first set of ranging measurement signals is sent in a first ranging slot after the first set of one or more ranging slots, wherein at least a first ranging measurement signal in the second set of ranging measurement signals is received in the first ranging slot, wherein at least a second ranging measurement signal in the first set of ranging measurement signals is sent in a second ranging slot after the first ranging slot, and wherein at least a second ranging measurement signal in the second set of ranging measurement signals is received in the second ranging slot (block 1230). For example, a first wireless communication device (e.g., using Fig.16 The communication manager 1608, TWR component 1610 and / or UWB component 1612 depicted in FIG. 120 may perform the operations of block 1230 as described above.

[0116] Process 1200 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0117] In a first aspect, the first wireless communication device is an initiator device and the second wireless communication device is a responder device.

[0118] In a second aspect, alone or in combination with the first aspect, the first RF technology is a narrowband technology and the second RF technology is an ultra-wideband technology.

[0119] In a third aspect, alone or in combination with one or more of the first and second aspects, process 1200 includes sending a plurality of ranging measurement signals to the second wireless communication device within a plurality of milliseconds.

[0120] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the first set of ranging measurement signals is interleaved with the second set of ranging measurement signals, so that the first ranging measurement signal in the second set of ranging measurement signals is received from the second wireless communication device after the first wireless communication device sends the first ranging measurement signal in the first set of ranging measurement signals and before the first wireless communication device sends the second ranging measurement signal in the first set of ranging measurement signals, and so that the second ranging measurement signal in the second set of ranging measurement signals is received from the second wireless communication device after the first wireless communication device sends the second ranging measurement signal in the first set of ranging measurement signals.

[0121] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 1200 includes: receiving a response message from the second wireless communication device using the first RF technology, wherein the response message is received after sending the time and / or frequency synchronization message and before sending the first ranging measurement signal in the first set of ranging measurement signals.

[0122] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the response message is received in the first set of one or more ranging slots.

[0123] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the response message includes an early termination request from the second wireless communication device.

[0124] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the early termination request indicates that the two-way ranging process should be terminated after a plurality of transmitted ranging measurement signals.

[0125] In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, the plurality of transmitted ranging measurement signals are based at least in part on received power measurements associated with the time and / or frequency synchronization message.
