[0003] Ultra wideband (UWB) technology is a wireless communication (or ranging, sensing, etc.) technology that uses nanosecond non-sinusoidal narrow pulse signals. Due to its narrow pulse and extremely low radiation spectrum density, the UWB system has the advantages of strong multipath resolution, low power consumption, and strong confidentiality.

[0004] For ranging or perception scenarios, the accuracy of the measurement or perception results is closely related to the signal bandwidth. The larger the signal bandwidth, the higher the accuracy of the perception or ranging results. It is possible to consider sending and receiving the reference signal used for ranging or perception through the UWB system, and transmitting other reference signals and / or data through a narrowband protocol. This processing method can be understood as UWB ranging or perception assisted by a narrowband protocol.

[0005] In the current UWB ranging method assisted by narrowband protocols, in the ranging control phase, the responding end roughly estimates the number of UWB ranging signal segments required for the ranging phase in the current UWB ranging round based on the power strength of the narrowband signal received from the initiating end, which may mislead the initiating end in configuring the parameters of the ranging phase and reduce system efficiency. Therefore, how to improve the performance of UWB ranging or sensing methods assisted by narrowband protocols has become an urgent problem to be solved. Summary of the invention

[0151] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0152] The embodiments of the present application can be applied to wireless personal area networks (WPAN) based on ultra-wideband (UWB) technology. The current standard adopted by WPAN is the Institute of Electrical and Electronics Engineers (IEEE) 802.15 series. WPAN can be used for communication between digital auxiliary devices within a small range such as telephones, computers, and auxiliary devices, and its working range is generally within 10m. Technologies supporting wireless personal area networks include Bluetooth, ZigBee, ultra-wideband, infrared data association (IrDA) infrared connection technology (infrared), home radio frequency (HomeRF), etc. It is easy for those skilled in the art to understand that various aspects involved in the present application can be extended to other networks using various standards or protocols. For example, Wireless Local Area Networks (WLAN), High Performance Radio LAN (HIPERLAN) (a wireless standard similar to the IEEE 802.11 standard, mainly used in Europe) and Wide Area Networks (WAN) or other networks now known or developed later. From the perspective of network composition, WPAN is located at the bottom layer of the entire network architecture and is used for wireless connections between devices within a small range, that is, point-to-point short-distance connections, which can be regarded as short-distance wireless communication networks. According to different application scenarios, WPAN is divided into high rate (HR)-WPAN and low rate (low rate)-WPAN. Among them, HR-WPAN can be used to support various high-rate multimedia applications, including high-quality audio and video distribution, multi-megabyte music and image document transmission, etc. LR-WPAN can be used for general business in daily life.

[0153] In WPAN, devices can be divided into full-function devices (FFD) and reduced-function devices (RFD) according to their communication capabilities. FFD devices can communicate with each other and with RFD devices. RFD devices cannot communicate directly with each other, but can only communicate with FFD devices, or forward data outward through an FFD device. The FFD device associated with the RFD is called the coordinator of the RFD. The coordinator can also control and associate multiple FFDs. The coordinator is also called a control node. There can be multiple coordinators in each ad hoc network. RFD devices are mainly used for simple control applications, such as light switches, passive infrared sensors, etc. The amount of data transmitted is small, and the transmission resources and communication resources are not occupied much. The cost of RFD devices is low. Among them, the coordinator can also be called a personal area network (PAN) coordinator. PAN coordinator can be understood as a type of coordinator, and PAN coordinator is also called the central control node of PAN, etc. FFD can be used as a PAN coordinator or coordinator, while RFD cannot be used as a PAN coordinator or coordinator. The PAN coordinator is the master node of the entire network, and there can be only one PAN coordinator in each ad hoc network, which has member identity management, link information management, and packet forwarding functions. Optionally, the device in the embodiment of the present application can be a device that supports multiple WPAN standards such as 802.15.4a and 802.15.4z, and 802.15.4ab or subsequent versions.

[0154] In the embodiments of the present application, the above-mentioned device may be a communication server, a router, a switch, a bridge, a computer or a mobile phone, a smart home device, a vehicle-mounted communication device, etc.

[0155] In an embodiment of the present application, the above-mentioned device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and a memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through a process, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a windows operating system. The application layer includes applications such as a browser, an address book, a word processing software, and an instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application, as long as it can communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be an FFD or an RFD, or a functional module in an FFD or RFD that can call a program and execute the program.

[0156] In addition, various aspects or features of the present application can be implemented as methods, devices or products using standard programming and / or engineering techniques. The term "product" used in this application covers computer programs that can be accessed from any computer-readable device, carrier or medium. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks or tapes, etc.), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards and flash memory devices (e.g., erasable programmable read-only memory (EPROM), cards, sticks or key drives, etc.). In addition, the various storage media described herein may represent one or more devices and / or other machine-readable media for storing information. The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing and / or carrying instructions and / or data.

[0157] The embodiments of the present application may also be applicable to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X). Of course, the embodiments of the present application may also be applicable to other possible communication systems, such as the Long Term Evolution (LTE) system, the LTE frequency division duplex (FDD) system, the LTE time division duplex (TDD) system, the universal mobile telecommunication system (UMTS), the worldwide interoperability for microwave access (WiMAX) communication system, the fifth generation (5G) communication system, and the future sixth generation (6G) communication system.

[0158] The above-mentioned communication system applicable to the present application is only an example for illustration, and the communication system applicable to the present application is not limited to this. A unified description is given here and no further elaboration is given below.

[0159] Figure 1 is a schematic diagram of two application scenarios provided by this application. Figure 1 In the system 101 shown in (A), multiple FFD devices and multiple RFD devices form a star topology communication system, in which one FFD is a PAN controller. In the star topology communication system, the PAN controller transmits data with one or more other devices, that is, multiple devices can establish a one-to-many or many-to-one data transmission architecture. Figure 1 In the system 102 shown in (B), multiple FFD devices and one RFD device form a communication system with a peer to peer topology or a mesh topology, in which one FFD is a PAN controller. In the communication system with a peer to peer topology, a many-to-many data transmission architecture can be established between multiple different devices.

[0160] It should be understood that Figure 1 (A) and Figure 1 (B) is a simplified schematic diagram for ease of understanding and does not limit the application scenarios of the present application. For example, the system 101 and / or the system 102 may also include other FFDs and / or RFDs. For another example, the PAN coordinator in the system 101 and / or the system 102 may also be a coordinator.

[0161] In order to facilitate understanding of the technical solutions of the embodiments of the present application, some terms or concepts that may be involved in the embodiments of the present application are first briefly described.

[0162] 1. UWB technology: It is a wireless communication / ranging / sensing technology that uses nanosecond non-sinusoidal narrow pulse signals, so it occupies a wide spectrum range. Due to its narrow pulse and extremely low radiation spectrum density, the UWB system has the advantages of strong multipath resolution, low power consumption, strong confidentiality, etc., which is conducive to coexistence with other systems, thereby improving spectrum utilization and system capacity.

[0163] With the approval of UWB technology for civilian use by the Federal Communications Commission (FCC) in 2002, ultra-wideband wireless communication has become one of the most popular physical layer technologies for short-distance, high-speed wireless networks. Many world-renowned companies, research institutions, and standardization organizations have actively invested in the research, development, and standardization of ultra-wideband wireless communication technology. The Institute of Electrical and Electronic Engineers (IEEE) has incorporated UWB technology into its IEEE 802 series of wireless standards and has released the WPAN standard IEEE 802.15.4a based on UWB technology, as well as its evolved version IEEE 802.15.4z. Currently, the formulation of the next-generation UWB technology WPAN standard 802.15.4ab has also been put on the agenda.

[0164] Since UWB technology does not require the use of carrier waves in traditional communication systems, but instead transmits data by sending and receiving extremely narrow pulses of nanoseconds or less, it has very high requirements for the time synchronization of the transceiver equipment. At the same time, due to its large communication bandwidth, when sending and receiving signals on ultra-wideband channels, the power consumption and complexity of the equipment are high, and most UWB communication devices are battery-driven. The next generation standard hopes to further reduce the power consumption of the UWB system, so a narrowband signal-assisted method can be used to send and receive all signals except for the reference signals for ranging and perception through a narrowband system, thereby reducing the overall power consumption overhead.

[0165] 2. Power of UWB signals: Since the bandwidth of the ultra-wideband system is very large, in order to reduce its interference to other narrowband devices during operation, the FCC has strictly restricted the power spectrum density of UWB signals. According to the Code of Federal Regulations (CFR), there are two main rules:

[0166] Rule 1: The maximum power spectral density (PSD) of the transmitted UWB signal cannot be greater than 41.3dBm per MHz on average within one millisecond.

[0167] Rule 2: The maximum power of the transmitted UWB signal within any 50M bandwidth cannot exceed 1 milliwatt.

[0168] Rule 1 limits the total energy transmitted by UWB within 1 millisecond (e.g. 37nJ at 500M bandwidth), but by concentrating the energy in a shorter period of time, the instantaneous power of the transmitted signal is increased to increase the signal coverage and the signal-to-noise ratio of the received signal at the receiving end. Based on this, in some scenarios where the transmission power needs to be increased, the transmitter splits the UWB signal to be transmitted into multiple segmented signals, each of which is less than 1 millisecond in length, and then only sends one of the segmented signals in each millisecond.

[0169] For ease of understanding, combined Figure 2 Briefly introduce UWB signal, Figure 2 It is a schematic diagram of a UWB signal provided in an embodiment of the present application.

[0170] from Figure 2 As can be seen from the figure, the transmitter splits the UWB signal to be transmitted into multiple segment signals (such as Figure 2 The UWB segment signal #1, UWB segment signal #2 and UWB segment signal #3 ... shown in FIG, each segment signal is less than 1 millisecond in time length, and one of the segment signals is sent in each millisecond. The signal type of the segment signal is also a UWB signal.

[0171] In addition, in the present application, "segmented signal" may also be referred to as "block signal", "short signal", "partial signal", "segment" or "block", etc. The name of the segmented signal is not limited, and can be used to identify that a certain UWB signal is split into multiple UWB signals, each of the multiple UWB signals after the split is less than 1 millisecond in time length, and a split UWB signal is sent in each millisecond. Optionally, the multiple segmented signals obtained by splitting the UWB signal can be the same, for example, the multiple segmented signals obtained by splitting the UWB signal are preambles of the same configuration, wherein the preambles of the same configuration include but are not limited to: the length of the preamble, the sequence used for the preamble, etc.

[0172] As can be seen from the above, splitting the UWB signal to be transmitted into multiple segmented signals for segmented transmission can increase the instantaneous power of the UWB signal, but it cannot be increased infinitely. Rule 2 actually limits the power increase multiple of UWB segmented transmission.

[0173] Exemplarily, in the present application, UWB segmented transmission may also be referred to as multi-millesecond transmission (MMS).

[0174] 3. Impulse Radio Ultra Wideband (IR-UWB) System: Due to the large bandwidth of the ultra-wideband system, its equipment needs to have ultra-high-speed data transmission and reception capabilities. However, the spectrum efficiency of the IR-UWB system based on pulse transmission is low. When transmitting the same information, the power consumption overhead required by the IR-UWB solution is much higher than that of other narrowband short-range protocols (for example, Bluetooth or ZigBee).

[0175] 4. Ranging or perception: For ranging or perception scenarios, the accuracy of the measurement or perception results is related to the signal bandwidth. The larger the signal bandwidth, the higher the accuracy of the perception or ranging results. Therefore, it is possible to consider sending and receiving reference signals used for ranging or perception through the UWB system, while transmitting other reference signals and / or data through narrowband protocols, thereby ensuring the accuracy of ranging and perception and saving power consumption. Among them, the perception involved in this application can be understood as the underlying perception technology of the Internet of Things technology architecture, which is the primary link for the Internet of Things to obtain information and realize object control; ranging can be understood as the measurement of the distance between devices, including but not limited to the distance measurement between two objects in the Internet of Things.

[0176] Exemplarily, the UWB technical solution combining narrow-band assisted UWB and multi-millisecond transmission in the present application may also be referred to as narrow-band assisted multi-millisecond Ultra-wideband (NBA-MMS UWB).

[0177] For ease of understanding, the ranging and positioning system used in the above-mentioned ranging technology is briefly introduced in conjunction with 3. Figure 3 Schematic diagram of the architecture of the ranging and positioning system provided in the embodiment of the present application. Figure 3 As shown, the ranging and positioning system includes multiple devices (such as Figure 3 The device 1 and device 2 shown in the figure may be the apparatus involved in the embodiment of the present application, and each device includes at least a UWB module. Further, the device may also include a narrowband communication module. Among them, the UWB modules of device 1 and device 2 can perform any one of ranging positioning and communication. If the device includes a narrowband communication module, data can be transmitted between the narrowband communication modules of device 1 and device 2 through a wireless link.

[0178] In this application, the UWB module can be understood as a device, chip or system that implements UWB wireless communication technology; accordingly, the narrowband communication module can be understood as a device, chip or system that implements narrowband communication technology (such as Wi-Fi, Bluetooth, or Zigbee (Purple Bee Protocol)). In a device, the UWB module and the narrowband communication module can be different devices or chips. Of course, the UWB module and the narrowband communication module can also be integrated in one device or chip. The embodiments of this application do not limit the implementation of the UWB module and the narrowband communication module in the device. UWB technology enables communication devices to have high data throughput and high precision in device positioning.

[0179] The device involved in the present application may be a wireless communication chip, a wireless sensor or a wireless communication terminal. For example, a user terminal, a user device, an access device, a subscriber station, a subscriber unit, a mobile station, a user agent, and a user equipment that support Wi-Fi communication functions, wherein the user terminal may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, Internet of Things (IoT) devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), terminal, terminal equipment, portable communication devices, handheld devices, portable computing devices, entertainment devices, gaming devices or systems, global positioning system devices, or any other suitable devices configured to communicate over a wireless medium. In addition, the device may support 802.15.4ab or the next generation of 802.15.4ab. The device can also support multiple standards such as 802.15.4a, 802.15.4-2011, 802.15.4-2015 and 802.15.4z. The device can also support multiple wireless local area networks (WLAN) standards of the 802.11 family such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, and 802.11be next generation.

[0180] 5. Figure of merit (FoM) field: In the previous generation IEEE 802.15.4z standard and earlier UWB standards, the FoM field is used to evaluate the confidence of the ranging signal. Specifically, the FoM field is used to indicate the accuracy of estimating the arrival time of the ranging signal.

[0181] Exemplarily, the arrival time of the ranging signal is used to determine the ranging result, and the FoM field is used to indicate the accuracy of the estimated arrival time of the ranging signal. It can also be understood that the FoM field is used to evaluate the credibility of the ranging result. In this application, the FoM field can also be called a ranging confidence field, which is used to indicate the ranging confidence.

[0182] Specifically, the ranging confidence field is shown in Table 1 below:

[0183] Table 1: Ranging confidence field list

[0184] Bits:0-2 3-4 5-6 7 Confidence Confidence interval Confidence interval weighting factor Extended fields

[0185] The specific content and meaning of the "Confidence" field in Table 1 are shown in Table 2 below.

[0186] Table 2: Confidence field content

[0187]

[0188] The higher the confidence value in Table 2, the more reliable the current distance measurement result is. Among them, 'no FoM' in Table 2 means that the current distance measurement result is wrong or cannot be used.

[0189] 6. Ranging round: In the previous generation IEEE 802.15.4z standard, a single ranging process is defined as a ranging round. The minimum processing time unit of each ranging round is the ranging slot. In a ranging round, there are three phases: ranging control phase, ranging phase, and measurement report phase. Figure 4 As shown, Figure 4 This is a schematic diagram of the various stages of a UWB ranging wheel. Figure 4 It can be seen that in IEEE 802.15.4z, the ranging control phase includes one ranging time slot, while in the IEEE 802.15.4ab standard currently under discussion, the ranging control phase may include more than one ranging time slot.

[0190] It should be noted that the signaling transmission method provided in this application can be applied not only to UWB ranging assisted by narrowband protocol, but also to UWB sensing or other measurement processes assisted by narrowband protocol. Figure 4The ranging control phase shown in can be understood as a type of measurement control phase, the ranging phase can be understood as a type of measurement phase, and the ranging result reporting phase can be understood as a type of measurement result reporting phase. For example, when the method for transmitting signaling provided in this application is applied to the UWB perception process assisted by a narrowband protocol, the measurement control phase can be understood as the perception control phase, the measurement phase can be understood as the perception phase, and the measurement result reporting phase can be understood as the perception result reporting phase.

[0191] In addition, it should be noted that the names of the different stages in the above-mentioned single measurement round are only examples and do not constitute any limitation on the scope of protection of this application. For example, the above-mentioned measurement control stage can be understood as a stage for configuring the parameters required in the measurement round; for another example, the above-mentioned measurement stage can be understood as a stage for performing measurement; for another example, the above-mentioned measurement result reporting stage can be understood as a stage for reporting measurement results, and can also be called the end of the measurement stage.

[0192] For ease of understanding, the following Figure 5 A UWB ranging method assisted by a narrowband protocol is briefly introduced. Figure 5 It is a schematic diagram of a UWB ranging method. Figure 5 The initiator and responder are included. As an example but not limitation, the initiator may be a device with communication capability in the WPAN (e.g. Figure 1 Similarly, the responder can also be a device with communication capabilities in the WPAN (such as Figure 1 FFD or RFD shown in ).

[0193] In addition, the structures of the initiator and responder can be as follows Figure 3 The structure shown in the device 1 or the device 2 shown in , for example, the initiator and the responder include a UWB module and a narrowband communication module.

[0194] from Figure 5 It can be seen that the initiator and the responder exchange narrowband (NB) signals to complete the configuration and synchronization processes required for UWB NBA-MMS ranging. For example, the initiator sends a narrowband polling signal (Poll), and the responder responds with a response signal (Resp) to shake hands. Among them, the information carried by the Poll signal includes but is not limited to one or more of the following: ranging round related parameter configuration, ranging signal preamble related parameter configuration (preamble length, preamble sequence, etc.), UWB packet type (SP0~SP3), device role and time slot scheduling allocation, etc.

[0195] In the ranging control phase, the responding end roughly estimates the number of segmented signals of the UWB ranging signal that need to be used in the ranging phase in the current UWB ranging round according to the power strength of the NB signal received from the initiating end (e.g., when the power strength of the NB signal is large, the signal-to-noise ratio (SNR) is high, the signal quality is good, and the number of segmented signals used is determined to be small; or, when the power strength of the NB signal is small, the SNR is low, the signal quality is poor, and the number of segmented signals used is determined to be large), and feeds back the roughly estimated number of segmented signals of the UWB ranging signal to the initiating end. The initiating end refers to the number of segmented signals fed back by the responding end to determine the number of segmented signals of the UWB ranging signal required in the ranging phase.

[0196] Specifically, after receiving the response frame, the initiator uses segmented transmission on the UWB channel to measure the round-trip time with the responder. After the measurement is completed, the responder sends the measurement result (report) to the initiator through the narrowband system.

[0197] Combination of the above Figure 1 The following describes the application scenarios of the present invention and briefly introduces the basic concepts involved in the present invention. Figure 5 A UWB ranging method is briefly introduced. This method has the following problems:

[0198] NB channels and UWB channels have different bandwidths and signal waveforms, resulting in large differences in NB channel and UWB channel conditions and different channel attenuation levels. Specifically, UWB signals have ultra-short pulse durations of nanoseconds, high temporal resolution, and a wide transmission bandwidth. In an indoor multipath environment, a UWB receiver can coherently increase the pulse energy received from each multipath component to provide gain for the reception of a single path. According to existing research, in indoor multipath conditions, the UWB received signal level strength value can fluctuate within +-5dB relative to the average level strength value. Therefore, the probability of deep fading in UWB signals is low, and it can effectively resist multipath fading.

[0199] In contrast, NB signals are more susceptible to multipath signals. According to existing research, in the case of indoor multipath, the NB received signal level strength can fluctuate by -20 to -30 dB relative to the average value. Therefore, NB signals are more likely to experience deep fading and are less likely to resist multipath fading.

[0200] In summary, Figure 5Under the UWB ranging method shown, if the responding end uses the NB signal strength to roughly estimate the number of segmented signals of the UWB ranging signal required in the UWB ranging phase, serious distortion will occur, thereby misleading the initiating end to configure the parameters of the ranging phase, reducing the system efficiency. For example, the initiating end may incorrectly configure a large number of segmented signals of the UWB ranging signal for the ranging phase, resulting in a long ranging time, affecting the access of other ranging users and the implementation of ranging tasks, increasing system latency, and reducing system efficiency. In addition, an incorrect configuration of the number of segmented signals of the UWB signal may result in an inappropriate configuration of the receiver start-up period of the receiving end / transmitting end device, thereby causing the receiving end / transmitting end device to be unable to effectively sleep and consume power too quickly, affecting the working time of the receiving end / transmitting end device. In order to solve the problems existing in the above-mentioned UWB ranging method, the present application provides a method for transmitting signaling, by determining the number of segmented signals of the UWB signal transmitted in the measurement phase according to the UWB signal transmitted in the control phase, thereby improving the accuracy of determining the number of segmented signals of the UWB signal. The following will describe in detail the method for transmitting signaling provided by the present application in conjunction with the accompanying drawings.

[0201] The embodiments shown below do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of the present application. As long as it is possible to communicate according to the method provided in the embodiments of the present application by running a program that records the code of the method provided in the embodiments of the present application, for example, the execution subject of the method provided in the embodiments of the present application can be a transceiver device, or a functional module in the transceiver device that can call and execute the program.

[0202] In order to facilitate understanding of the embodiments of the present application, the following explanations are made.

[0203] First, in this application, "used to indicate" may include direct indication and indirect indication. When describing that a certain information is used to indicate A, it may include that the information directly indicates A or indirectly indicates A, but it does not mean that the information must carry A.

[0204] The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each piece of information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0205] Second, the first, second, and various numerical numbers (e.g., "#1", "#2", etc.) shown in the present application are only for convenience of description and are used to distinguish objects, and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different channels, etc., rather than to describe a specific order or sequence. It should be understood that the objects described in this way can be interchanged where appropriate so as to be able to describe solutions other than the embodiments of the present application.

[0206] Third, in this application, "pre-configuration" may include pre-definition, such as protocol definition. Among them, "pre-definition" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including each network element), and this application does not limit its specific implementation method.

[0207] Fourth, the "storage" involved in the embodiments of the present application may refer to storage in one or more memories. The one or more memories may be separately set or integrated in an encoder or decoder, a processor, or a communication device. The one or more memories may also be partially separately set and partially integrated in a decoder, a processor, or a communication device. The type of memory may be any form of storage medium, which is not limited by the present application.

[0208] Fifth, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0209] Sixth, the "protocol" involved in the embodiments of the present application may refer to a standard protocol in the communication field, for example, it may include a WiFi protocol and related protocols used in future communication systems, and the present application does not limit this.

[0210] Hereinafter, without loss of generality, the method for transmitting signaling provided by the embodiment of the present application is described in detail by taking the interaction between a transmitting end device and a receiving end device as an example. The transmitting end device may also be referred to as a transmitting end, and the receiving end device may also be referred to as a receiving end.

[0211] As an example but not limitation, the transmitting device may be a device with communication capability in the WPAN, such as an FFD or an RFD; similarly, the receiving device may also be a device with communication capability in the WPAN, such as an FFD or an RFD.

[0212] It should be understood that the specific types and names of the transmitting device and the receiving device are not limited in this application, and any communication device that can send and receive UWB signals and NB signals is sufficient.

[0213] Figure 6 This is a schematic flow chart of a method for transmitting signaling provided in an embodiment of the present application, comprising the following steps:

[0214] S610: The transmitting end device transmits a first UWB signal to the receiving end device, or in other words, the receiving end device receives the first UWB signal from the transmitting end device.

[0215] Specifically, the transmitting device sends a first UWB signal to the receiving device in the control phase of the first round. The first round can be any measurement round in the measurement process, and the control phase is used to complete the initial configuration of the measurement round. The measurement includes a measurement process such as ranging or perception based on the UWB signal. For example, the first round is any ranging round; or, for example, the first round is any perception round.

[0216] For example, the receiving device receives a first UWB signal from the transmitting device in the ranging control phase, and the transmitting device needs at least one ranging time slot to send the first UWB signal. In this embodiment, the ranging control phase may include more than one ranging time slot, wherein at least one ranging time slot of the more than one ranging time slot is used to send the first UWB signal.

[0217] In this embodiment, the first UWB signal is used to determine first indication information, and the first indication information is used to indicate a first number of segmented signals of the second UWB signal. The segmented signals of the second UWB signal can be understood as segmented signals obtained by splitting the second UWB signal.

[0218] Optionally, the segmented signals included in the second UWB signal are identical, for example, the segmented signals included in the second UWB signal are preambles of identical configuration, wherein the preambles of identical configuration include but are not limited to: the length of the preamble, the sequence used by the preamble, and the like.

[0219] For the sake of distinction, the first UWB signal may be referred to as a UWB test signal, and the second UWB signal may be referred to as a UWB measurement signal. The second UWB signal includes a UWB ranging signal and / or a UWB sensing signal, and the second UWB signal may be understood as a UWB signal for implementing measurement transmitted during the first round of measurement phase (e.g., ranging phase, sensing phase, etc.).

[0220] It should be noted that the specific function of the second UWB signal in the embodiment of the present application is not limited. It can be a UWB signal for ranging, a UWB signal for sensing, or a UWB signal for realizing other measurement functions, which are not illustrated one by one here.

[0221] In addition, the first number of segmented signals of the second UWB signal can be understood as: the second UWB signal is split into a plurality of segmented signals (such as Figure 2 As shown), each segmented signal is less than 1 millisecond in time length, and then only one of the segmented signals is sent in each millisecond, wherein the number of the plurality of segmented signals is recorded as a first number. Exemplarily, the segmented signals in the plurality of segmented signals are the same, for example, the segmented signals in the plurality of segmented signals may be preambles of the same configuration, wherein the preambles of the same configuration include but are not limited to: the length of the preamble, the sequence used for the preamble, and the like.

[0222] Optionally, when the number of segmented signals of the second UWB signal expected by the transmitting device is different from the number of segmented signals of the second UWB signal expected by the receiving device, the transmitting device and the receiving device can negotiate to obtain a suitable number of segmented signals of the second UWB signal for transmission. The negotiation process will be described below in conjunction with specific steps and will not be repeated here.

[0223] As a possible implementation, the first indication information implicitly indicates the number of segmented signals. For example, the first indication information is a number index of segmented signals, and the number index of segmented signals is used to indicate the first number of segmented signals of the second UWB signal expected by the transmitting end device; for another example, the first indication information is a FoM value corresponding to the first UWB signal, and the FoM value is used to determine the first number of segmented signals of the second UWB signal expected by the transmitting end device.

[0224] For example, the transmitting device and the receiving device obtain or locally store a second mapping relationship (e.g., the transmitting device and the receiving device negotiate and determine and store the second mapping relationship, or the second mapping relationship is predefined by the protocol), and the second mapping relationship is a mapping relationship between the number index of the segmented signal and the number of the segmented signal. That is, after the transmitting device receives the number index of the segmented signal, it can determine the number of the segmented signal according to the second mapping relationship stored locally.

[0225] Exemplarily, the second mapping relationship is shown in Table 3a below:

[0226] Table 3a: Mapping relationship between the number index of segment signals and the number of segment signals

[0227]

[0228] Wherein, FNI represents the number index of the segmented signal (Fragment Number Index, FNI).

[0229] For another example, the transmitting end device and the receiving end device obtain or locally store a third mapping relationship (e.g., the transmitting end device and the receiving end device negotiate and determine and store the third mapping relationship, or the third mapping relationship is predefined by the protocol), and the third mapping relationship is a mapping relationship between the FoM value and the number of segmented signals. That is, after the transmitting end device receives the above FoM value, it can determine the number of segmented signals according to the locally stored third mapping relationship.

[0230] Exemplarily, the third mapping relationship is shown in Table 3b below:

[0231] Table 3b: Mapping relationship between FoM value and number of segmented signals

[0232] FoM value Number of segment signals 0 32 1 16 2 8 3 4 4 2 5 1 6 1 7 1

[0233] As another possible implementation, the first indication information displays the number of segmented signals. For example, the value of the first indication information is the number of segmented signals.

[0234] For example, when the first indication information value is 1, it indicates that the number of segmented signals is 1; when the first indication information value is 2, it indicates that the number of segmented signals is 2... and so on, when the first indication information value is N, it indicates that the number of segmented signals is N, where N is a positive integer.

[0235] It should be understood that the above is only an example of a possible form of the first indication information, and does not constitute any limitation on the protection scope of the present application. Other indication information that can be used to indicate the number of segmented signals is within the protection scope of the present application. For example, the first indication information indicates the confidence level corresponding to the first UWB signal, and the confidence level corresponding to the first UWB signal is used to determine the first number of segmented signals of the second UWB signal expected by the transmitting device. For ease of description, the following description takes the first indication information as an index of the number of segmented signals as an example.

[0236] From the above, it can be known that the first UWB signal is used to determine the first indication information. After receiving the first UWB signal, the receiving end device can determine the first indication information based on the first UWB signal. Optionally, Figure 6 The method flow shown also includes:

[0237] S620: The receiving end device determines first indication information according to the first UWB signal.

[0238] Specifically, the receiving end device determines the first indication information according to the first UWB signal, including the following steps:

[0239] Step 1: The receiving end device determines the confidence level corresponding to the first UWB signal according to the quality of the first UWB signal.

[0240] For example, when the quality of the first UWB signal is good, it is determined (or estimated) that the confidence corresponding to the first UWB signal is high, and optionally, the corresponding FoM value is large; or, when the quality of the first UWB signal is poor, it is estimated that the confidence corresponding to the first UWB signal is low, and optionally, the corresponding FoM value is small.

[0241] It should be understood that this embodiment does not limit how to determine the confidence level corresponding to the first UWB signal based on the quality of the first UWB signal. Reference may be made to the description of determining the confidence level corresponding to a model based on signal quality in the current related art, which will not be repeated here.

[0242] Further, after determining the confidence level corresponding to the first UWB signal, step 2 is performed.

[0243] Step 2: The receiving end device determines first indication information according to the confidence level corresponding to the first UWB signal.

[0244] For example, the confidence and the number of segmented signals of the second UWB signal have a mapping relationship (referred to as a first mapping relationship for ease of distinction), and the receiving end device can determine the number of segmented signals of the second UWB signal according to the confidence and the first mapping relationship, thereby determining the first indication information. The first mapping relationship is a mapping relationship between the confidence and the number of segmented signals.

[0245] Exemplarily, the first mapping relationship is shown in Table 4a and Table 4b below:

[0246] Table 4a: Example 1 of the mapping relationship between confidence and the number of segmented signals

[0247] Confidence Index Confidence Number of segment signals FNI 0 No FoM 32 101 1 20％ 16 100 2 55％ 8 011 3 75％ 4 010 4 85％ 2 001 5 92％ 1 000 6 97％ 1 000 7 99％ 1 000

[0248] Table 4b: Example 2 of the mapping relationship between confidence and the number of segmented signals

[0249] Confidence Index Confidence Number of segment signals FNI 0 No FoM 16 100 1 20％ 8 011 2 55％ 4 010 3 75％ 4 010 4 85％ 2 001 5 92％ 2 001 6 97％ 2 001 7 99％ 1 000

[0250] It should be noted that the above Table 4a and Table 4b indicate examples of possible forms of the above first mapping relationship, which do not constitute any limitation on the protection scope of the present application. The first mapping relationship may also have other forms that can be used to indicate the relationship between the confidence and the number of segmented signals. For example, the above Table 4a and Table 4b include two columns of confidence and the number of segmented signals, and the confidence index and FNI are optional. Examples are not given one by one here.

[0251] It can be seen from Table 4a and Table 4b above that the higher the confidence level corresponding to the first UWB signal, the higher the confidence level of the device in estimating the arrival time of the signal transmitted by the UWB system, and therefore, the smaller the number of UWB signal segment signals transmitted by the corresponding estimated UWB system.

[0252] Exemplarily, in order to enable the receiving end device to learn relevant configuration of the first UWB signal, optionally, Figure 6 The method flow shown also includes:

[0253] S611: The transmitting end device transmits first configuration information to the receiving end device, or in other words, the receiving end device receives the first configuration information from the transmitting end device.

[0254] The first configuration information is used to indicate the configuration of the first UWB signal.

[0255] Exemplarily, the first configuration information may be sent via a narrowband signal, such as being carried in the first narrowband signal. Specifically, in this embodiment, in order to improve the accuracy of receiving the first UWB signal, the receiving end device receives a first narrowband signal from the transmitting end device before receiving the first UWB signal, and the first narrowband signal includes the first configuration information, and the first configuration information is used to indicate the configuration of the first UWB signal.

[0256] For example, when the transmitting device is a ranging initiating device and the receiving device is a ranging responding device, the poll signal sent by the initiating end to the responding end during the ranging control phase includes first configuration information, and the first configuration information is used to indicate the configuration of the first UWB signal. For example, the poll signal includes but is not limited to: information indicating the length of the preamble code of the first UWB signal, information indicating the sequence used for the preamble code of the first UWB signal, etc. As a possible implementation method, the above-mentioned first UWB signal is a UWB signal sent during the control phase of the first measurement round in the measurement process, and the above-mentioned first configuration information can be carried by a narrowband signal transmitted during the control phase (such as a poll signal, a response signal, or a newly added narrowband signal sent during the control phase of the first measurement round).

[0257] As another possible implementation, if the above-mentioned first UWB signal is a UWB signal sent in the control phase of measurement round #1 after the first measurement round in the measurement process, then the above-mentioned first configuration information may not be sent. For example, the relevant configuration of the first UWB signal may follow the configuration of the UWB signal sent in the previous measurement round; or, the first configuration information may be carried in a poll signal sent in the control phase of measurement round #1; or, the first configuration information may also be sent before the poll signal sent in the control phase of measurement round #1.

[0258] Further, after determining the first indication information, the receiving end device sends the first indication information to the transmitting end device so that the transmitting end device learns the first number of segmented signals of the second UWB signal determined by the receiving end device. Figure 6 The method flow shown also includes:

[0259] S630: The receiving device sends first indication information to the sending device, or in other words, the sending device receives the first indication information from the receiving device.

[0260] Exemplarily, the first indication information is transmitted via narrowband. In other words, the first indication information may be a narrowband signal. As a possible implementation, in this embodiment, the receiving device may carry the first indication information in a predefined first information element and send it to the transmitting device (e.g., the first information element is transmitted via narrowband). The predefined first information element is an information element that the transmitting device can parse. The first information element also includes a first address size description field and / or a first address field, wherein the first address size description field is used to indicate the address type of the device receiving the first information element, and the first address field is used to indicate the address of the device receiving the first information element.

[0261] For example, the first information element is a predefined FoM-based UWB segment number estimation information element (FoMbased Fragment Number Estimation Information Element, FFNE IE). The design of FFNE IE is shown in Table 5:

[0262] Table 5: FFNE IE

[0263] Bits:0-1 2-4 5-7 Octets:0 / 2 / 8 Address Size Specifier FNI Reserved Address

[0264] Among them, the Address Size Specifier field indicates the address type of the device receiving the FFNE IE. The address size specification field can also be other names, as long as it can indicate the address type of the device receiving the first information element, and this application does not limit it. The address type may include one or more of the following: short address (i.e., address length is 2 bytes), long address (i.e., address length is 8 bytes). Optionally, the indication rule is consistent with the previous generation UWB standard IEEE 802.15.4z, that is:

[0265] -00: indicates no address, that is, 0 byte (Octet);

[0266] -01: ​​reserved;

[0267] -10: indicates a short address, which is 2 bytes (Octet), corresponding to 16 bits;

[0268] -11: indicates a long address, that is, 8 bytes (Octet), corresponding to 64 bits.

[0269] When the value of the Address Size Specifier field of the FFNE IE is 00, the Address field is 0, that is, it does not contain address information. It can be understood that the receiving end device broadcasts the FFNE IE. In other words, after the receiving end device generates the first information element, it can broadcast the first information element.

[0270] As another possible implementation manner, the receiving device may directly send the first indication information to the sending device without carrying the first indication information in the first information element.

[0271] For example, the receiving device sends the first indication information to the transmitting device according to the source address of the received first UWB signal.

[0272] For example, the newly added FFNE IE can be recognized and processed by a device that needs to perform ranging or sensing functions. As a possible implementation, the corresponding recognition and processing method of the newly added FFNE IE is similar to the recognition and processing method of the nested IE (e.g., RDM IE) specified in the existing protocol 802.15.4z, and the recognition and processing method of the nested IE in the existing protocol 802.15.4z can be referred to.

[0273] For example, the upper protocol layer of the sending device configures the FFNE IE and transmits it to the MAC layer of the sending device.

[0274] For another example, the MAC layer of the receiving end device transfers the received FFNE IE to the upper layer protocol of the receiving end device, and the upper layer of the protocol identifies and processes the FFNE IE.

[0275] As a possible implementation, the newly added FFNE IE can be transmitted via a narrowband frequency band.

[0276] As another possible implementation, the newly added FFNE IE can also be transmitted via the UWB band.

[0277] For ease of understanding, the newly added FFNE IE is introduced in detail below in conjunction with Table 6.

[0278] Table 6 below is an extension and continuation of Table 7-18 (Table 7-18) of the existing 802.15.4z protocol. For the sake of brevity, the existing definition of Table 7-18 in the protocol is not reflected in Table 6 below. Specifically, it can be seen from Table 6 below that the newly added FFNE IE can be added to the nested IE list defined in Table 7-18 (Table 7-18) of the existing 802.15.4z protocol as a newly added IE in the 802.15.4ab protocol or a subsequent version of the protocol. Specifically, a reserved sub-ID value (Sub-ID value) in the nested IE list defined in Table 7-18 (Table 7-18) of the existing 802.15.4z protocol can be used to indicate the newly added FFNE IE.

[0279] Table 6:

[0280] Sub-ID value IE Name Data Used by Created by T FFNE IE X Upper Layer Upper Layer

[0281] Wherein, T in Table 6 may be any one or more values ​​from 0x5d to 0x7f. Table 6 may be an extension and continuation of the nested IE list defined in Table 7-18 of the existing 802.15.4z protocol. X in Table 6 indicates that the FFNE IE belongs to the Data type IE.

[0282] Optionally, the message carrying the first indication information may be called a UWB block quantity feedback message, and the UWB block quantity feedback message is a narrowband signal. As a possible implementation method, the response message (Resp) of the receiving device to the Poll message and the UWB block quantity feedback message fed back by the receiving device to the transmitting device may be included in the same return message, that is, after receiving the Poll message, the receiving device may not need to respond immediately, but wait until the first number of segmented signals of the second UWB signal is received to determine, and then respond to the Poll message and the UWB test block at the same time through one message, which is suitable for scenarios where a fast two-way narrowband handshake connection is not required between the transmitting device and the receiving device.

[0283] Exemplarily, in a certain ranging time slot after the transmitting device and the receiving device complete the polling initiation (Poll) and response (Resp) respectively, the transmitting device sends a UWB block (such as the first UWB signal mentioned above) for testing (training) purposes to the receiving device. That is, the Resp message of the receiving device and the UWB block quantity feedback message fed back by the receiving device to the initiator are two different messages. That is to say, after receiving the Poll message, the receiving device can respond to the Poll message, and after receiving the first UWB signal to determine the first number of segmented signals of the second UWB signal, send the first indication information, which is suitable for scenarios where a fast two-way handshake connection needs to be carried out between the initiator and the responder.

[0284] It should be understood that the above is only an example of how the receiving device sends the first indication information to the sending device, and does not constitute any limitation on the scope of protection of this application. In this embodiment, there is no limitation on how the receiving device sends the first indication information to the sending end, and it is sufficient to be able to send the first indication information to the sending device.

[0285] Optionally, after receiving the above-mentioned first indication information, the transmitting end device can learn the first number of segmented signals of the second UWB signal expected by the receiving end device. The transmitting end device may also notify the receiving end device of the second number of segmented signals of the second UWB signal expected by the transmitting end device through the second indication information, or the transmitting end device may also notify the receiving end device of the fourth number of segmented signals of the second UWB signal expected by the transmitting end device through the second indication information.

[0286] In this embodiment, the transmitting end device determines the number of segment signals of the second UWB signal expected by the transmitting end device in the following two ways:

[0287] Method 1: The transmitting end device determines the first number of segmented signals of the second UWB signal indicated by the received first indication information.

[0288] In method 2, Figure 6 The method flow shown also includes:

[0289] S621: The transmitting end device determines a second number of segment signals of the second UWB signal according to a first number of segment signals of the second UWB signal.

[0290] As a possible implementation, the second number is the same as the first number. The transmitting end device agrees to transmit the second UWB signal based on the first number, and in the first round of measurement phase, the transmitting end device uses the first number to carry out the UWB measurement process.

[0291] In this implementation, the transmitting device may notify the receiving device through the second indication information that the UWB measurement process can be carried out based on the first quantity; or, the transmitting device may not notify the receiving device; or, the transmitting device may notify the receiving device through the confirmation information (ACK) that the UWB measurement process can be carried out based on the first quantity.

[0292] As another possible implementation, the second number is different from the first number. Exemplarily, the reference factors that affect the sending end device in determining the second number include but are not limited to:

[0293] a) When there are multiple receiving-end devices, each receiving-end device feeds back a first number. For example, when the first numbers fed back by the multiple receiving-end devices are different, the transmitting-end device uses the largest first number among them as the second number.

[0294] Exemplarily, when there are multiple transmitting devices, the method for each transmitting device to determine the second number of segmented signals of the second UWB signal can refer to the above-mentioned situation of one transmitting device to multiple receiving devices. That is to say, the situation of multiple transmitting devices to multiple receiving devices can be understood as a multiple-to-many situation, which will not be repeated here.

[0295] b) Confidence history information of the UWB signal from multiple previous measurement rounds.

[0296] Method 2: When the noise levels of the UWB receivers of the transmitting device and the receiving device are greatly different, it is necessary to consider the UWB reception signal qualities of the UWB receivers of the transmitting device and the receiving device together to determine the final number of UWB block signals.

[0297] In method 2, Figure 6 The method flow shown also includes:

[0298] S622: The receiving device sends a fifth UWB signal to the transmitting device. In other words, the transmitting device receives the fifth UWB signal from the receiving device.

[0299] Similar to the function of the first UWB signal sent by the transmitting device to the receiving device in S610 above, the fifth UWB signal is used by the transmitting device to estimate the number of segmented signals of the second UWB signal transmitted in the measurement phase (such as the ranging phase, the sensing phase, etc.) for implementing the measurement.

[0300] Exemplarily, the fifth UWB signal may also be referred to as a UWB test signal.

[0301] As a possible implementation manner, the first indication information fed back by the receiving device to the transmitting device and the fifth UWB signal initiated by the receiving device to the transmitting device are not limited in the order of sending time slots.

[0302] For example, the receiving device may first send the fifth UWB signal to the transmitting device, and then send the first indication information to the transmitting device, which is suitable for a scenario where the receiving device needs more time to process the first UWB signal from the transmitting device.

[0303] For another example, the receiving device may first send the first indication information to the transmitting device, and then send the fifth UWB signal to the transmitting device.

[0304] For example, after the receiving device sends the fifth UWB signal, it feeds back a response message (Resp) to the transmitting device. The Resp message not only includes a response to the Poll, but also includes the first indication information to be fed back to the transmitting device. It can be understood that the Resp message and the UWB block quantity feedback message fed back by the receiving device to the initiator are combined.

[0305] Optionally, in mode 2, since the UWB test signal needs to be exchanged between the transmitting device and the receiving device, the above-mentioned poll signal can also be used to schedule the transmission order of the UWB test signal and the narrowband signal of the transmitting device and the receiving device in the ranging control phase.

[0306] For example, the poll signal is used to indicate the time slots occupied by transmitting the first UWB signal, the first indication information, the fifth UWB signal, and the second indication information described below.

[0307] S623: The transmitting end device determines a fourth number of segmented signals of the second UWB signal according to the first indication information and / or the fifth UWB signal.

[0308] Exemplarily, in the second method, the transmitting device can determine the number of segmented signals of the second UWB signal transmitted in the measurement phase according to the narrowband signal responded by the receiving device (eg, the first indication information) and / or the received wideband signal (eg, the fifth UWB signal).

[0309] For example, the transmitting end device determines the number of segmented signals of the second UWB signal according to the received first indication information, which is similar to the above-mentioned step S621 and will not be described in detail here.

[0310] For another example, the transmitting end device determines the number of segmented signals of the second UWB signal transmitted in the measurement phase according to the received wideband signal (e.g., the fifth UWB signal). For example, the fifth UWB signal is used to determine the fifth number of segmented signals of the second UWB signal, and the transmitting end device determines that the number of segmented signals of the second UWB signal is greater than or equal to the fifth number.

[0311] For another example, the transmitting end device determines the number of segmented signals of the second UWB signal transmitted in the measurement phase according to the received first indication information and the broadband signal (eg, the fifth UWB signal).

[0312] As a possible implementation, the fifth UWB signal is used to determine the fifth number of segmented signals of the second UWB signal. Specifically, under the second method, the transmitting end device can combine the first number of segmented signals of the second UWB signal indicated by the first indication information and the fifth number of segmented signals of the second UWB signal determined by itself according to the fifth UWB signal, and finally determine the fourth number of segmented signals of the second UWB signal transmitted in the measurement phase (e.g., ranging phase, perception phase, etc.) for implementing measurement.

[0313] Exemplarily, the transmitting end device uses the larger value of the first number of segmented signals of the second UWB signal and the fifth number of segmented signals of the second UWB signal as the fourth number of segmented signals of the second UWB signal; or, the transmitting end device uses the average of the first number of segmented signals of the second UWB signal and the fifth number of segmented signals of the second UWB signal as the fourth number of segmented signals of the second UWB signal. It should be understood that in this embodiment, there is no limitation on how the transmitting end device determines the fourth number of segmented signals of the second UWB signal based on the first number of segmented signals of the second UWB signal and the fifth number of segmented signals of the second UWB signal. The transmitting end device can take into account the received first indication information and / or the fifth UWB signal in the process of determining the fourth number of segmented signals of the second UWB signal. The transmitting end device can notify the receiving end device of the number of segmented signals of the second UWB signal expected by the transmitting end device through the second indication information. Figure 6 The method flow shown also includes:

[0314] S631: The sending end device sends second indication information to the receiving end device, or in other words, the receiving end device receives the second indication information from the sending end device.

[0315] Specifically, the second indication information is used to indicate the number of segmented signals of the second UWB signal transmitted in the first round of measurement phase.

[0316] Corresponding to the above-mentioned method 1, the second indication information is used to indicate the second number of segmented signals of the second UWB signal; corresponding to the above-mentioned method 2, the second indication information is used to indicate the fourth number of segmented signals of the second UWB signal.

[0317] Exemplarily, the second indication information is transmitted via a narrowband. In other words, the second indication information may be a narrowband signal.

[0318] Exemplarily, the second indication information is carried in a notification message, and the notification message is used to schedule and indicate the sending order of the segmented signals of the second UWB signal. The notification message may be a narrowband signal.

[0319] In addition, it should be noted that the message name is not limited in the embodiment of the present application. The above-mentioned message carrying the second indication information can be called a notification message or have other names.

[0320] Optionally, the notification message may be included in a Ranging Control Message (RCM).

[0321] As a possible implementation, the RCM uses the information element defined in the previous generation IEEE 802.15.4z standard. The RCM is used for basic configuration and scheduling instructions for ranging measurement, including but not limited to: scheduling instructions for the sending order of ranging participating devices, configuration of ranging round parameters, configuration of ranging block structure parameters, configuration of UWB channels and preambles used for ranging, etc. In this implementation, by reusing some information elements in the existing RCM, the sending order of segmented signals of the scheduling instructions UWB signal is realized, which can improve the backward compatibility of the solution.

[0322] As another possible implementation manner, the RCM may be a newly defined message including one or more information elements, and is used to perform basic configuration and scheduling instructions for the UWB signal in the measurement phase.

[0323] In this embodiment, there is no limitation on RCM, and messages that can be used to perform basic configuration and scheduling instructions for the segmented signals of the UWB signal in the measurement phase are within the protection scope of this application. For example, the RCM involved in this embodiment can also be a message including one or more information elements specified in the existing protocol and a newly added information element.

[0324] Similar to the first indication information mentioned above, as a possible implementation method, in this embodiment, the sending device can carry the second indication information in a predefined second information element and send it to the receiving device, wherein the second information element also includes a second address size description field and a second address field, wherein the second address size description field is used to indicate the address type of the device receiving the second information element, and the second address field is used to indicate the address of the device receiving the second information element.

[0325] The format of the second information element is similar to the format of the first information element described above, and will not be described in detail here.

[0326] Exemplarily, the parameter configurations of the first UWB signal (and / or the fifth UWB signal) and the second UWB signal may be different. For example, parameters such as the preamble type and length may be different. The initiator may update the configuration of the preamble of the second UWB signal (and / or the fifth UWB signal), including but not limited to: the preamble length, the sequence used for the preamble, etc. The update process may be carried by the narrowband signal NB. Optionally, Figure 6 The method flow shown also includes:

[0327] S632: The transmitting end device transmits the second configuration information to the receiving end device, or in other words, the receiving end device receives the second configuration information from the transmitting end device.

[0328] The second configuration information is used to indicate the configuration of the second UWB signal (and / or the fifth UWB signal). Exemplarily, the second configuration information may be sent via a narrowband signal, such as the second configuration information is carried in the second narrowband signal.

[0329] As a possible implementation, the second narrowband signal and the second indication information are one narrowband signal. It can be understood that when the second narrowband signal carrying the second configuration information and the narrowband signal carrying the second indication information (such as the UWB block quantity feedback message) are one narrowband signal, signaling transmission time can be saved and effectiveness can be ensured. Figure 6 In the process shown, the receiving device can be a measurement initiator or a measurement responder. The following describes the process of the signaling transmission method provided by the present application when the receiving device plays different roles in the ranging process with specific examples.

[0330] Example 1: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the control device in the ranging process. The control device can be understood as a device that determines relevant parameters in the ranging process.

[0331] Figure 7(a) is a schematic flow chart corresponding to Example 1, comprising the following steps:

[0332] Step 1: The initiating device sends a polling signal to the responding device.

[0333] Specifically, the polling signal includes but is not limited to: first ranging round related parameter configuration, UWB signal preamble related parameter configuration (such as preamble length, sequence used by preamble, etc.), UWB packet type (SP0-SP3), device role and time slot scheduling allocation, etc.

[0334] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0335] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0336] Step 3: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.

[0337] For the first UWB signal description, please refer to Figure 6 The description of the first UWB signal in the illustrated embodiment will not be repeated here.

[0338] Step 4: The responding device sends the first indication information to the initiating device.

[0339] For the description of the first indication information, please refer to Figure 6 The description of the first indication information in the illustrated embodiment will not be repeated here.

[0340] Exemplarily, the first indication information may be sent in combination with a response signal for responding to the above-mentioned polling signal. Figure 7 This situation is not shown in (a) in FIG.

[0341] Step 5: The initiating device sends second indication information to the responding device.

[0342] For the description of the second indication information, please refer to Figure 6 The description of the second indication information in the illustrated embodiment will not be repeated here.

[0343] Step 6: The initiating device sends a second narrowband signal to the responding device.

[0344] For the description of the second narrowband signal, please refer to Figure 6 The description of the second narrowband signal in the illustrated embodiment will not be repeated here.

[0345] After step 1 to step 6, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured by the second narrowband signal to perform subsequent processes of UWB ranging.

[0346] For example, the second indication information indicates that the number of segment signals of the UWB ranging signal is 4.

[0347] Example 2: The sending device is a responding device of ranging, the receiving device is an initiating device of ranging, and the sending device is a controlling device in the ranging process.

[0348] Figure 7 (b) is a schematic flow chart corresponding to Example 2, comprising the following steps:

[0349] Step 1: The initiating device sends a polling signal to the responding device.

[0350] Specifically, the polling signal includes but is not limited to: first ranging round related parameter configuration, UWB signal preamble related parameter configuration (such as preamble length, sequence used by preamble, etc.), UWB packet type (SP0-SP3), device role and time slot scheduling allocation, etc.

[0351] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0352] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0353] Step 3: In the ranging control phase, the responding device sends a first UWB signal to the initiating device.

[0354] Step 4: The initiating device sends first indication information to the responding device.

[0355] Step 5: The initiating device sends a second narrowband signal to the responding device.

[0356] For the description of the second narrowband signal, please refer to Figure 6 The description of the second narrowband signal in the illustrated embodiment will not be repeated here.

[0357] After step 1 to step 5, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured by the second narrowband signal to perform subsequent processes of UWB ranging.

[0358] For example, the first indication information indicates that the number of segment signals of the UWB ranging signal is 4.

[0359] Example 3: The transmitting device is an initiating device of ranging, the receiving device is a responding device of ranging, and also includes a control device.

[0360] Figure 7 (c) is a schematic flow chart corresponding to Example 3, comprising the following steps:

[0361] Step 1: The initiating device (or controlling device) sends a polling signal to the responding device.

[0362] Specifically, the polling signal includes but is not limited to: first ranging round related parameter configuration, UWB signal preamble related parameter configuration (such as preamble length, sequence used by preamble, etc.), UWB packet type (SP0-SP3), device role and time slot scheduling allocation, etc.

[0363] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0364] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0365] Step 3: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.

[0366] Step 4: The responding device sends the first indication information to the controlling device.

[0367] For the description of the first indication information, please refer to Figure 6 The description of the first indication information in the illustrated embodiment will not be repeated here.

[0368] Exemplarily, the first indication information may be sent in combination with a response signal for responding to the above-mentioned polling signal. Figure 7 (c) in FIG. 1 does not show this situation.

[0369] Step 5: The control device sends indication information #1 to the initiating device and the responding device respectively.

[0370] The control device determines whether to transmit the second UWB signal based on the first number of blocks. When the control device determines to transmit the second UWB signal based on the first number of blocks, the control device sends indication information #1 to the receiving device and the transmitting device. For example, broadcasting cell #1, cell #1 includes indication information #1; and for another example, sending indication cell #2 and cell #3 to the receiving device and the transmitting device, respectively, cell #2 and cell #3 include indication information #1.

[0371] Step 6: The initiating device (or the controlling device) sends a second narrowband signal to the responding device.

[0372] After step 1 to step 6, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured by the second narrowband signal to perform subsequent processes of UWB ranging.

[0373] For example, the above indication information #1 indicates that the number of segment signals of the UWB ranging signal is 4.

[0374] Specifically, Figure 7 (a) to (c) in the embodiment are directed to the transmitting end device determining the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving end device, Figure 6 It can be seen from the process shown in that the transmitting end device can also determine the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving end device and / or the UWB test signal sent by the receiving end. The following takes the transmitting end device as an initiating end device of ranging, the receiving end device as a responding end device of ranging, and the initiating end device as a control device in the ranging process as an example. In the case where the transmitting end device determines the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving end device and / or the UWB test signal sent by the receiving end, Figure 6 The specific process of the embodiment described.

[0375] As a possible implementation method, the following steps are included:

[0376] Step 1a: The initiating device sends a polling signal to the responding device.

[0377] Exemplarily, the polling signal is used to indicate the order of sending the UWB test signal and the narrowband signal of the initiating end device and the responding end device in the ranging control phase.

[0378] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0379] Step 2a: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.

[0380] For the first UWB signal description, please refer to Figure 6 The description of the first UWB signal in the illustrated embodiment will not be repeated here.

[0381] Step 3a: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0382] Exemplarily, a response message (Resp) of the responding device to the Poll message and a UWB block quantity feedback message fed back by the responding device to the initiating device are included in the same return message.

[0383] Step 4a: The responding device sends a fifth UWB signal to the initiating device.

[0384] The fifth UWB signal related description can refer to Figure 6 The description of the fifth UWB signal in the illustrated embodiment will not be repeated here.

[0385] Step 5a: The initiating end device sends second indication information to the responding end device.

[0386] For the description of the second indication information, please refer to Figure 6 The description of the second indication information in the illustrated embodiment will not be repeated here.

[0387] Step 6a: The initiating device sends a second narrowband signal to the responding device.

[0388] For the description of the second narrowband signal, please refer to Figure 6 The description of the second narrowband signal in the illustrated embodiment will not be repeated here.

[0389] After step 1a to step 6a, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured by the second narrowband signal to perform subsequent processes of UWB ranging.

[0390] The above steps 1a to 6a are as follows Figure 7 As shown in (d), it should be noted that the order of the above steps 1a to 6a is not limited.

[0391] Another possible implementation method includes the following steps:

[0392] Step 1b: The initiating device sends a polling signal to the responding device.

[0393] Exemplarily, the polling signal is used to indicate the order of sending the UWB test signal and the narrowband signal of the initiating end device and the responding end device in the ranging control phase.

[0394] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0395] Step 2b: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0396] Step 3b: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.

[0397] For the first UWB signal description, please refer to Figure 6 The description of the first UWB signal in the illustrated embodiment will not be repeated here.

[0398] Step 4b: The responding end device sends the first indication information to the initiating end device.

[0399] In this implementation, the Resp message sent by the responding device and the UWB block quantity feedback message fed back by the responding device to the initiating device are not combined.

[0400] Step 5b: The responding device sends a fifth UWB signal to the initiating device.

[0401] The fifth UWB signal related description can refer to Figure 6 The description of the fifth UWB signal in the illustrated embodiment will not be repeated here.

[0402] Step 6b: The initiating device sends second indication information to the responding device.

[0403] For the description of the second indication information, please refer to Figure 6 The description of the second indication information in the illustrated embodiment will not be repeated here.

[0404] Step 7b: The initiating device sends a second narrowband signal to the responding device.

[0405] For the description of the second narrowband signal, please refer to Figure 6 The description of the second narrowband signal in the illustrated embodiment will not be repeated here.

[0406] The above steps 1b to 6b are as follows Figure 7 As shown in (e) in .

[0407] As another possible implementation, the following steps are included:

[0408] Step 1c: The initiating device sends a polling signal to the responding device.

[0409] Exemplarily, the polling signal is used to indicate the order of sending the UWB test signal and the narrowband signal of the initiating end device and the responding end device in the ranging control phase.

[0410] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0411] Step 2c: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0412] Step 3c: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.

[0413] For the first UWB signal description, please refer to Figure 6 The description of the first UWB signal in the illustrated embodiment will not be repeated here.

[0414] Step 4c: The responding device sends a fifth UWB signal to the initiating device.

[0415] The fifth UWB signal related description can refer to Figure 6 The description of the fifth UWB signal in the illustrated embodiment will not be repeated here.

[0416] Step 5c: The responding end device sends the first indication information to the initiating end device.

[0417] In this implementation, the Resp message sent by the responding device and the UWB block number feedback message fed back by the responding device to the initiating device are not merged. The responding device first sends the Resp message and then feeds back the UWB block number feedback message, which is suitable for the scenario where the responding device needs more time to process the UWB test signal from the initiating device.

[0418] Step 6c: The initiating device sends second indication information to the responding device.

[0419] For the description of the second indication information, please refer to Figure 6 The description of the second indication information in the illustrated embodiment will not be repeated here.

[0420] Step 7c: The initiating device sends a second narrowband signal to the responding device.

[0421] For the description of the second narrowband signal, please refer to Figure 6 The description of the second narrowband signal in the illustrated embodiment will not be repeated here.

[0422] The above steps 1c to 6c are as follows Figure 7 As shown in (f) in .

[0423] As another possible implementation, the following steps are included:

[0424] Step 1d: The initiating device sends a polling signal to the responding device.

[0425] Exemplarily, the polling signal is used to indicate the order of sending the UWB test signal and the narrowband signal of the initiating end device and the responding end device in the ranging control phase.

[0426] Exemplarily, the polling signal can be understood as Figure 6 The illustrated embodiment involves a first narrowband signal.

[0427] Step 2d: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.

[0428] For the first UWB signal description, please refer to Figure 6 The description of the first UWB signal in the illustrated embodiment will not be repeated here.

[0429] Step 3d: The responding device sends a fifth UWB signal to the initiating device.

[0430] Step 4d: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0431] Exemplarily, a response message (Resp) of the responding device to the Poll message and a UWB block quantity feedback message fed back by the responding device to the initiating device are included in the same return message.

[0432] The fifth UWB signal related description can refer to Figure 6 The description of the fifth UWB signal in the illustrated embodiment will not be repeated here.

[0433] Step 5d: The initiating device sends second indication information to the responding device.

[0434] For the description of the second indication information, please refer to Figure 6 The description of the second indication information in the illustrated embodiment will not be repeated here.

[0435] Step 6d: The initiating device sends a second narrowband signal to the responding device.

[0436] For the description of the second narrowband signal, please refer to Figure 6 The description of the second narrowband signal in the illustrated embodiment will not be repeated here.

[0437] The above steps 1d to 6d are as follows Figure 7 As shown in (g) in .

[0438] Similarly, for the case where the transmitting device determines the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving device and / or the UWB test signal sent by the receiving end, wherein the transmitting device is a responding device of ranging, the receiving device is an initiating device of ranging, and the transmitting device is a control device in the ranging process, the case where the transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the control device in the ranging process is similar to the above-mentioned transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the control device in the ranging process. For example, Figure 7 In (d) to (g), the device sending the first indication information and / or the first UWB signal is replaced by the initiating device, and the device sending the fifth UWB signal is replaced by the responding device, and in this case the Resp message will not be sent in combination with the first indication information.

[0439] in addition, Figure 7 (d) to (g) show the case where the initiating device is a controlling device. If the responding device is a controlling device, the initiating device needs to return to the responding device the fifth number of segmented signals of the UWB signal determined based on the fifth UWB signal, and the responding device ultimately determines the number of segmented signals of the UWB signal based on the received information indicating the fifth number and the first UWB signal, and notifies the initiating device through a notification message.

[0440] The above embodiments are all described by taking a one-to-one situation as an example, that is, one initiating end device and one responding end device. Figure 6 The signaling transmission method shown can also be extended to one-to-many or many-to-many situations, that is, one initiating end device and multiple responding end devices, or multiple initiating end devices and multiple responding end devices.

[0441] For example, a one-to-many situation such as Figure 7 As shown in (h) in .

[0442] The Poll message in the ranging control phase can be used to schedule and indicate the sending order of multiple UWB test signals and multiple narrowband signals of the initiating device and multiple responding devices in the ranging control phase.

[0443] For example, the initiator device is respectively instructed to send the time slots occupied by the UWB test signal and the narrowband signal, and the multiple responders are instructed to send the time slots occupied by multiple UWB test signals and multiple narrowband signals.

[0444] As a possible implementation manner, the initiating end device may send a notification message in the ranging control phase to notify the number of segmented signals of the second UWB signal in the measurement phase.

[0445] Optionally, the notification message in the ranging control phase may also be used to schedule and indicate the order of sending segmented signals of multiple second UWB signals of the initiating end device and multiple responding end devices in a subsequent measurement phase.

[0446] For example, the announcement message is used to indicate the time slots occupied by the initiator device and multiple responder devices for sending segmented signals.

[0447] The following example illustrates how the initiating device determines the number of segmented signals of the second UWB signal transmitted in the measurement phase in a one-to-many situation.

[0448] Assuming there are N responder devices, the number of segmented signals generated by each responder device is estimated to be F1, F2...F N .

[0449] In the case where the transmitting end device determines the number of segment signals of the second UWB signal according to the number of segment signals fed back by the responding end device:

[0450] The sending device can convert F1, F2...F N The maximum value among is used as the number of segmented signals of the second UWB signal transmitted in the measurement phase.

[0451] In the case where the transmitting end device determines the number of segment signals of the second UWB signal according to the number of segment signals fed back by the responding end device and the number of segment signals estimated by itself:

[0452] Corresponding to the UWB test signals (eg, the fifth UWB signals) respectively sent by the multiple responding end devices, the transmitting end device accordingly sets the number of multiple segmented signals, which is recorded as F N+1 , F N+2 ...F 2N A simple method for determining the number of segment signals of the final second UWB signal is, F1, F2...F N and F N+1 , F N+2 ...F 2N The maximum number of segmented signals in is taken as the number of segmented signals of the second UWB signal, that is:

[0453] The number of segment signals of the second UWB signal = max(F1, F2...F 2N )

[0454] In the many-to-many case, the method for each initiating device to determine the number of segmented signals of the second UWB signal can refer to the above one-to-many case, that is, the many-to-many case can be understood as the many-to-many case, which will not be repeated here.

[0455] From the above, we can see that Figure 6In the embodiment shown, in the ranging control stage, the number of UWB blocks can be estimated based on the quality of the UWB test signal, which is more accurate than the existing solution based on the estimation of the narrowband NB signal, reduces the probability of incorrectly configuring the number of UWB blocks, and avoids or reduces the probability of reduced system efficiency.

[0456] also, Figure 6 The illustrated embodiment can avoid or reduce the probability of inappropriate configuration of the receiver on period of the receiving / transmitting device, thereby avoiding or reducing the probability of the receiving / transmitting device being unable to effectively sleep and consuming power too quickly, thereby avoiding or reducing the probability of a reduction in the working time of the receiving / transmitting device.

[0457] In addition, the present application also provides another method for transmitting signaling, which adjusts the inappropriate number of UWB blocks to the appropriate number of UWB blocks in time according to the actual measurement effect of the current ranging round, thereby avoiding wasting a lot of time in the subsequent continuous ranging process, thereby improving the system efficiency. The method for transmitting signaling will be described in detail below with reference to the accompanying drawings.

[0458] Unless otherwise specified, the specific description of some technical features in one embodiment can also be used to explain the corresponding technical features mentioned in other embodiments. Figure 6 The specific description of the segmented signal of the UWB signal in the embodiment shown can be applied to Figure 8 In the embodiment shown, Figure 8 The embodiment shown does not need to elaborate on the concept of segmented signals. For example, Figure 6 The specific description of determining the number of segmented signals of a UWB signal according to the confidence level of the UWB signal in the illustrated embodiment can be applied to Figure 8 In the embodiment shown, no further examples are given here.

[0459] Figure 8 It is a schematic flow chart of another method for transmitting signaling provided by the present application, comprising the following steps:

[0460] S810: The transmitting end device determines third indication information according to at least one segment signal of a fourth UWB signal.

[0461] The third indication information is used to indicate a third number of segmented signals of the third UWB signal. The fourth UWB signal is a UWB signal for measurement (e.g., sensing or ranging) transmitted in the current measurement round, and the UWB signal is split into multiple segmented signals for transmission during the transmission process, and the transmitting end device is a device that receives the multiple segmented signals.

[0462] In this embodiment, the transmitting end device can determine the actual measurement effect of the current measurement round according to the quality of the received segmented signal, and determine that the number of segmented signals of the current UWB signal is no longer appropriate and needs to be changed (or updated).

[0463] As a possible implementation manner, the transmitting end device may determine the third indication information according to any segment signal of the received fourth UWB signal.

[0464] For example, the transmitting end device determines the third indication information according to the quality of any one of the multiple segmented signals received. Specifically, the method of determining the number of segmented signals of the UWB signal to be transmitted according to the quality of the UWB signal can refer to Figure 6 The description of “determining the first indication information according to the first UWB signal” in the illustrated embodiment will not be repeated here.

[0465] As another possible implementation manner, the transmitting end device may determine the third indication information according to a plurality of segment signals of the received fourth UWB signal.

[0466] For example, the transmitting end device determines the third indication information according to the average confidence value of the multiple received segmented signals.

[0467] It should be understood that the above is only an example of how to determine the third indication information according to the segmented signal, and does not constitute any limitation on the protection scope of the present application.

[0468] S820: The transmitting device sends third indication information to the controlling device, or the controlling device receives the third indication information from the transmitting device.

[0469] Exemplarily, the third indication information is transmitted via a narrowband. In other words, the third indication information may be a narrowband signal.

[0470] Similar to the first indication information mentioned above, as a possible implementation method, in this embodiment, the sending device can carry the third indication information in a predefined third information element and send it to the control device, wherein the third information element also includes a third address size description field and a third address field, wherein the third address size description field is used to indicate the address type of the device receiving the third information element, and the third address field is used to indicate the address of the device receiving the third information element.

[0471] The format of the third information element is similar to the format of the first information element described above, and will not be repeated here.

[0472] Optionally, the transmitting device may send second information to the control device to instruct to change the number of segmented signals of the third UWB signal. Figure 8The method flow shown also includes:

[0473] S830: The transmitting device transmits second information to the controlling device, or the controlling device receives second information from the transmitting device.

[0474] The second information is used to indicate the change in the number of segmented signals of the third UWB signal. Exemplarily, the second information is triggered by a ranging change request message (Ranging Change Request Information Element, RCR IE).

[0475] As a possible implementation, the RCR IE uses the information element defined in the previous generation IEEE 802.15.4z standard, and the RCR IE is used to trigger the ranging change request, including but not limited to: the change of ranging round parameter configuration, the change of ranging block structure, etc. In this implementation, by reusing the existing information element, the number of segmented signals indicating the UWB signal is changed, which can improve the backward compatibility of the solution.

[0476] As another possible implementation manner, the RCR IE may be a newly defined information element, which is used to indicate a change in the number of segment signals of the UWB signal.

[0477] In this embodiment, no limitation is imposed on the RCR IE, and any information element that can be used to indicate a change in the number of segmented signals of a UWB signal is within the protection scope of this application.

[0478] Exemplarily, the second information is transmitted via a narrowband, and the second information may be a narrowband signal.

[0479] Specifically, after receiving the third indication information, the control device may notify the transmitting end device through the first information whether it agrees to change the number of segments of the third UWB signal. Figure 8 The method flow shown also includes:

[0480] S840: The control device sends first information to the sending end device, or the sending end device receives the first information from the control device.

[0481] The first information is used to indicate whether to agree to change the number of segments of the third UWB signal.

[0482] Exemplarily, the first information is transmitted via a narrowband, and the first information may be a narrowband signal.

[0483] As a possible implementation manner, the first information indicates that updating the number of segments of the third UWB signal is agreed.

[0484] For example, the first information is confirmation information (ACK).

[0485] Optionally, in this implementation mode, after the control device sends the confirmation information, it can also indicate the third number of segmented signals of the third UWB signal by sending fourth indication information; or, it can also indicate the fourth number of segmented signals of the third UWB signal by sending fourth indication information, and the fourth number is different from the third number.

[0486] As another example, the first information is fourth indication information.

[0487] Specifically, in this implementation, the control device may send fourth indication information to both the transmitting device and the receiving device, so that the transmitting device and the receiving device may subsequently perform UWB signal transmission based on the number of segmented signals of the changed UWB signal. Optionally, Figure 8 The method flow shown also includes:

[0488] S850: The control device sends fourth indication information to the transmitting-end device and the receiving-end device, or the transmitting-end device and the receiving-end device receive the fourth indication information from the control device.

[0489] Exemplarily, the fourth indication information is transmitted via a narrowband, and the fourth indication information may be a narrowband signal.

[0490] Similar to the first indication information mentioned above, as a possible implementation method, in this embodiment, the sending device can carry the fourth indication information in a predefined fourth information element and send it to the control device, wherein the fourth information element also includes a fourth address size description field and / or a fourth address field, wherein the fourth address size description field is used to indicate the address type of the device receiving the fourth information element, and the fourth address field is used to indicate the address of the device receiving the fourth information element.

[0491] The format of the fourth information element is similar to the format of the first information element described above, and will not be described in detail here.

[0492] For example, the control device broadcasts the fourth information element.

[0493] For another example, the control device sends a fourth information cell #1 to a transmitting device, and the fourth address size description field and / or the fourth address field in the fourth information cell #1 indicate that the device receiving the fourth information cell #1 is a transmitting device. The fourth information cell #1 includes fourth indication information. And, the control device sends a fourth information cell #2 to a receiving device, and the fourth address size description field and / or the fourth address field in the fourth information cell #2 indicate that the device receiving the fourth information cell #2 is a receiving device. The fourth information cell #2 includes fourth indication information.

[0494] As another possible implementation manner, the first information indicates the number of segment signals that do not agree to update the third UWB signal.

[0495] It should be understood that this embodiment mainly considers the case where the control device agrees to update the number of segment signals of the third UWB signal, and does not elaborate on the case where the control device disagrees to update the number of segment signals of the third UWB signal.

[0496] As a possible implementation, the transmitting device may send the first information and the third indication information to the control device in the first round of measurement reporting phase. In this implementation, the control device may send the fourth indication information to the transmitting device and the receiving device in the first round of measurement reporting phase; or,

[0497] The control device may send fourth indication information to the transmitting end device and the receiving end device before the second round of measurement phase.

[0498] In this implementation, after receiving the fourth indication information, the transmitting device and the receiving device can transmit the third UWB signal based on the changed number of segmented signals in the second round of measurement phase, and the second round is the measurement round after the first round. According to the actual measurement effect of the current ranging round, the number of inappropriate segmented signals can be adjusted to the number of appropriate segmented signals in time to avoid wasting more time in the subsequent continuous ranging process, thereby improving system efficiency. In addition, this implementation can avoid or reduce the probability of inappropriate configuration of the receiver start-up period of the receiving end / transmitting end device, thereby avoiding or reducing the probability that the receiving end / transmitting end device cannot effectively sleep and consumes power too quickly, thereby avoiding or reducing the probability of a reduction in the working time of the receiving end / transmitting end device. It should be noted that the above-mentioned second round is the measurement round after the first round, which can be understood as: the second round is carried out after the first round ends.

[0499] Among them, the second round will be carried out after the first round, including the following two situations:

[0500] Case 1: The second round and the first round are two adjacent distance measuring rounds. Specifically, the second round can be started immediately after the first round ends, which can be understood as the end time of the first round is the start time of the second round, or the time between the end time of the first round and the start time of the second round is less than a preset threshold and no other distance measuring rounds are included in the time.

[0501] Case 2: The second round and the first round are not adjacent distance measuring rounds. Specifically, the second round does not start immediately after the first round ends. In other words, there can be a certain time interval between the second round and the first round, for example, there are other distance measuring rounds between the second round and the first round. It can be understood that the time between the end time of the first round and the start time of the second round is greater than the preset threshold.

[0502] The size of the preset threshold is not limited in the embodiment of the present application. For example, in case 2, the end time of the first round and the start time of the second round may be separated by the duration length of several rounds, wherein these separated rounds may be used for other ranging processes or left vacant.

[0503] Exemplarily, in case 2, the interval between the end time of the first round and the start time of the second round being greater than the preset threshold includes: the second round and the first round are not in the same ranging block, for example, the first round is a ranging round in the current ranging block, and the second round is a ranging round in the next ranging block (such as a ranging block adjacent to the current ranging block), at this time, the duration of several rounds is separated between the second round and the first round, wherein these several rounds can be used for other ranging processes or left vacant. For another example, the first round is a ranging round in the current ranging block, and the second round can be a ranging round in a subsequent ranging block (such as a ranging block separated from the current ranging block by at least one ranging block).

[0504] The above-mentioned distance measuring block can be understood as the time length including one or more distance measuring wheels.

[0505] As another possible implementation, the transmitting end device may send the first information and the third indication information to the control device at the first moment in the first round of measurement phase. In this implementation, the control device may send the fourth indication information to the transmitting end device and the receiving end device before the second round of measurement phase; or,

[0506] The control device may send fourth indication information to the transmitting end device and the receiving end device at the second moment in the measurement phase of the first round.

[0507] The third UWB signal includes a UWB signal transmitted in a second round of measurement phase and / or a UWB signal transmitted after a second time in the first round of measurement phase, where the second time is later than the first time.

[0508] In this implementation, after receiving the fourth indication information, the transmitting end device and the receiving end device can transmit the third UWB signal based on the changed number of segmented signals in the second round of measurement phase, and the second round is the measurement round after the first round; or, after receiving the fourth indication information, the transmitting end device and the receiving end device can transmit the third UWB signal based on the changed number of segmented signals after the second moment in the first round of measurement phase. According to the actual measurement effect of the current ranging round, the number of inappropriate segmented signals can be adjusted to the number of appropriate segmented signals in time, avoiding wasting more time in the remaining time of the measurement phase of the current ranging round and in the subsequent continuous multiple ranging processes, thereby improving system efficiency. In addition, this implementation can avoid or reduce the probability of inappropriate configuration of the receiver start-up period of the receiving end / transmitting end device, thereby avoiding or reducing the probability that the receiving end / transmitting end device cannot effectively sleep and consumes power too quickly, thereby avoiding or reducing the probability of a reduction in the working time of the receiving end / transmitting end device. Figure 8 In the process shown, the receiving device can be the initiating device of the measurement, or the responding device of the measurement; or, the initiating device and the control device are the same device, and the responding device and the control device are the same device. The following is a specific example to illustrate the process of the method for transmitting signaling provided by the present application when the receiving device plays different roles in the ranging process.

[0509] Example 4: The transmitting device is an initiating device of ranging, the receiving device is a responding device of ranging, and also includes a control device. The control device can be understood as a device that determines relevant parameters in the ranging process.

[0510] Fig. 9 The schematic flow chart corresponding to Example 4 includes the following steps:

[0511] Step 1: The initiating device sends a polling signal to the responding device.

[0512] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0513] Step 3: The initiator device and the responder device transmit UWB ranging signals to perform ranging.

[0514] In order to distinguish, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this example 4, the above Figure 8 The fourth UWB signal in the illustrated embodiment is fourth UWB signal #2.

[0515] The initiating end device determines the third indication information according to the received segment signal of the fourth UWB signal #2.

[0516] Step 4: The initiating device sends the second information and the third indication information to the control device.

[0517] Step 4 includes two possibilities:

[0518] Possibility 1: The initiating device sends the second information and the third indication information in the current ranging phase. Fig. 9 As shown in (a).

[0519] Possibility 2: The initiating device sends the second information and the third indication information during the ranging reporting phase. Fig. 9 As shown in (b).

[0520] Step 5: The control device sends the first information to the initiating device.

[0521] Step 6: The control device sends fourth indication information to the initiating device and the responding device.

[0522] Specifically, after receiving the third indication information, the control device sends the fourth indication information to the initiating end device and the responding end device. The following possibilities are included:

[0523] When the initiating device sends the second information and the third indication information in the current ranging phase, the control device may send the fourth indication information to the initiating device and the responding device in the current ranging phase; or, the control device may also start to send the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the ranging result reporting phase of the current ranging round or the control phase of the next ranging round), Fig. 9 In (a), sending the fourth indication information to the initiating end device and the responding end device during the ranging result reporting phase of the current ranging wheel is used as an example. The next ranging wheel may be a ranging wheel adjacent to the current ranging wheel, or may be a ranging wheel separated from the current ranging wheel by at least one ranging wheel.

[0524] When the initiating device sends the second information and the third indication information in the ranging reporting phase of the current ranging round, the control device may send the fourth indication information to the initiating device and the responding device in the ranging reporting phase of the current ranging round; or, the control device may also start to send the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the control phase of the next ranging round), Fig. 9 (b) is illustrated by taking sending the fourth indication information to the initiating end device and the responding end device in the ranging result reporting phase of the current ranging round as an example.

[0525] After step 1 to step 6, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform the subsequent process of UWB ranging.

[0526] For example, the fourth indication information indicates that the number of segment signals of the UWB ranging signal is 8. One possibility is that after the initiator device and the responder device receive the fourth indication information, in the period after the number of segment signals in the ranging phase of the current ranging round is changed, the changed number of segment signals is directly used to carry out ranging; another possibility is that after the initiator device and the responder device receive the fourth indication information, the changed number of segment signals will be used to carry out UWB ranging in the next UWB ranging round.

[0527] Example 5: The transmitting device is a responding device of ranging, the receiving device is an initiating device of ranging, and also includes a control device.

[0528] Fig.10 The schematic flow chart corresponding to Example 4 includes the following steps:

[0529] Step 1: The initiating device sends a polling signal to the responding device.

[0530] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0531] Step 3: The initiator device and the responder device transmit UWB ranging signals to perform ranging.

[0532] In order to distinguish, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this example five, the above Figure 8 The fourth UWB signal in the illustrated embodiment is fourth UWB signal #1.

[0533] The responding end device determines the third indication information according to the received segment signal of the fourth UWB signal #1.

[0534] Step 4: The responding device sends the second information and the third indication information to the controlling device.

[0535] Step 4 includes two possibilities:

[0536] Possibility 1: The responding end device sends the second information and the third indication information in the current ranging phase. Fig.10 As shown in (a).

[0537] Possibility 2: The responding end device sends the second information and the third indication information during the ranging reporting phase. Fig.10 As shown in (b).

[0538] Step 5: The control device sends the first information to the responding device.

[0539] Step 6: The control device sends fourth indication information to the initiating device and the responding device.

[0540] Specifically, after receiving the third indication information, the control device sends the fourth indication information to the initiating end device and the responding end device. The following possibilities are included:

[0541] When the initiating device sends the second information and the third indication information in the current ranging phase, the control device may send the fourth indication information to the initiating device and the responding device in the current ranging phase; or, the control device may also start to send the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the ranging result reporting phase of the current ranging round or the control phase of the next ranging round), Fig.10 (a) is illustrated by taking sending the fourth indication information to the initiating end device and the responding end device in the ranging result reporting phase of the current ranging round as an example.

[0542] When the initiating device sends the second information and the third indication information in the ranging reporting phase of the current ranging round, the control device may send the fourth indication information to the initiating device and the responding device in the ranging reporting phase of the current ranging round; or, the control device may also start to send the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the control phase of the next ranging round), Fig.10 (b) is illustrated by taking sending the fourth indication information to the initiating end device and the responding end device in the ranging result reporting phase of the current ranging round as an example.

[0543] After step 1 to step 6, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform the subsequent process of UWB ranging.

[0544] Example 6: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the controlling device in the ranging process.

[0545] Fig.11 The schematic flow chart corresponding to Example 6 includes the following steps:

[0546] Step 1: The initiating device sends a polling signal to the responding device.

[0547] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0548] Step 3: The initiator device and the responder device transmit UWB ranging signals to perform ranging.

[0549] In order to distinguish, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this example 4, the above Figure 8 The fourth UWB signal in the illustrated embodiment is fourth UWB signal #2.

[0550] The initiating end device determines the third indication information according to the received segment signal of the fourth UWB signal #2.

[0551] Step 4: The initiating device sends third indication information to the responding device.

[0552] Step 4 includes two possibilities:

[0553] Possibility 1: The initiating device sends the third indication information in the current ranging phase. Fig.11 As shown in (a).

[0554] Possibility 2: The initiating device sends the third indication information during the ranging reporting phase. Fig.11 As shown in (b).

[0555] After step 1 to step 4, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform the subsequent process of UWB ranging.

[0556] For example, when the initiating device sends the third indication information in the current ranging phase, after receiving the third indication information, the responding device directly uses the changed number of segmented signals to carry out ranging in the time period after the number of segmented signals in the ranging phase of the current ranging round is changed; another possibility is that the initiating device and the responding device will use the changed number of segmented signals to carry out UWB ranging in the next UWB ranging round.

[0557] For another example, when the initiating device sends the third indication information in the ranging reporting phase, the initiating device and the responding device will use the changed number of segmented signals to perform UWB ranging in the next UWB ranging round.

[0558] Example 7: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the responding device is the controlling device in the ranging process.

[0559] Fig.12 The schematic flow chart corresponding to Example 7 includes the following steps:

[0560] Step 1: The initiating device sends a polling signal to the responding device.

[0561] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.

[0562] Step 3: The initiator device and the responder device transmit UWB ranging signals to perform ranging.

[0563] In order to distinguish, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this example 4, the above Figure 8 The fourth UWB signal in the illustrated embodiment is fourth UWB signal #2.

[0564] The initiating end device determines the third indication information according to the received segment signal of the fourth UWB signal #2.

[0565] Step 4: The initiating device sends the second information and the third indication information to the responding device.

[0566] Step 4 includes two possibilities:

[0567] Possibility 1: The initiating device sends the second information and the third indication information in the current ranging phase. Fig.12 As shown in (a).

[0568] Possibility 2: The initiating device sends the second information and the third indication information during the ranging reporting phase. Fig.12 As shown in (b).

[0569] Step 5: The responding device sends fourth indication information to the initiating device.

[0570] Specifically, after receiving the third indication information, the responding end device sends the fourth indication information to the initiating end device. The following possibilities are included:

[0571] When the initiating device sends the second information and the third indication information in the current ranging phase, the responding device may send the fourth indication information to the initiating device in the current ranging phase; or, the responding device may also start to send the fourth indication information to the initiating device before the ranging phase of the next ranging round starts (e.g., the ranging result reporting phase of the current ranging round or the control phase of the next ranging round), Fig.12 (a) is illustrated by taking sending the fourth indication information to the initiating end device and the responding end device in the ranging result reporting phase of the current ranging round as an example.

[0572] When the initiating device sends the second information and the third indication information in the ranging reporting phase of the current ranging round, the responding device may send the fourth indication information to the initiating device in the ranging reporting phase of the current ranging round; or, the responding device may also start to send the fourth indication information to the initiating device before the ranging phase of the next ranging round starts (e.g., the control phase of the next ranging round), Fig.12 (b) is illustrated by taking sending the fourth indication information to the initiating end device and the responding end device in the ranging result reporting phase of the current ranging round as an example.

[0573] After step 1 to step 5, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform the subsequent process of UWB ranging.

[0574] Alternatively, when the receiving device is a responding device of ranging, and the responding device is a control device in the ranging process, the control device can directly indicate the number of segmented signals of the UWB ranging signal, without determining the number of segmented signals of the UWB ranging signal based on the third indication information sent by the initiating device. For example, after executing the above steps 1 and 3, execute:

[0575] Step 4a: The responding end device sends fourth indication information to the initiating end device.

[0576] Step 4a includes two possibilities:

[0577] Possibility 1: The responding end device sends the fourth indication information in the current ranging phase. Fig.12 As shown in (c).

[0578] Possibility 2: The responding end device sends the fourth indication information during the ranging reporting phase. Fig.12 As shown in (d).

[0579] After step 1 to step 4a, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform the subsequent process of UWB ranging.

[0580] Figure 6 and Figure 8 In the illustrated process, how to determine the number of segmented signals of the UWB signal transmitted in the measurement phase based on the UWB test signal and how to indicate the number of segmented signals of the UWB signal are described in detail.

[0581] As a possible implementation manner, the above-mentioned process in which the transmitting end device determines the number of segmented signals of the UWB signal transmitted in the measurement phase is a process that does not need to be triggered.

[0582] As another possible implementation, the transmitting device determines the number of segmented signals of the UWB signal transmitted during the measurement phase based on a process triggered by a trigger request sent by the receiving device. For example, the transmitting device may be a control device.

[0583] For example, the receiving device is a ranging responding device, and the sending device is a ranging initiating device. In the measurement reporting phase of the first round, if the responding device needs to change the number of segmented signals of the UWB signal transmitted in the measurement phase of the subsequent round (e.g., the second round), the reporting message related to the ranging result returned to the sending device (e.g., a narrowband signal) carries at least one of the following information:

[0584] A change request message, the updated number of segment signals (such as the FFNE IE message described above), information related to the change in the number of segment signals of the UWB signal, etc. The change request message is used to indicate the change in the number of segment signals of the UWB signal, for example, the change request message can be the RCR IE described above.

[0585] That is, the information related to the change in the number of segmented signals of the UWB signal can be combined with the report message related to the ranging result returned by the responding end device to the initiating end device and reported in one message.

[0586] For example, if the receiving device needs to change the number of segmented signals of the UWB signal transmitted in the measurement phase of the subsequent round (e.g., the second round) during the measurement phase of the first round, the receiving device may send a change request message (e.g., a narrowband signal) to the transmitting device. The change request message is used to request a change in the number of segmented signals of the UWB signal transmitted in the measurement phase of the subsequent round (e.g., the second round). The change request message includes at least one of the following information:

[0587] Change request message, the updated number of segmented signals (such as the FFNE IE message mentioned above), information related to the change of the number of UWB blocks, etc. The change request message is used to indicate the change of the number of segmented signals of the UWB signal, for example, the change request message can be the RCR IE mentioned above.

[0588] That is to say, the information related to the number of segmented signals of the UWB signal is transmitted during the measurement phase, that is, it does not need to be combined with the reporting message related to the ranging result. For example, the change request message and the UWB signal sent by the receiving device to the transmitting device can be interchanged in the order of sending time slots to adapt to different scenarios.

[0589] For example, the change request message is sent after the UWB signal sent by the receiving device to the transmitting device, which can be adapted to the scenario where the receiving device needs more time to process the segmented signal of the UWB signal from the initiator. For another example, the change request message is sent before the UWB signal sent by the receiving device to the transmitting device, which can be adapted to the scenario where the receiving device needs to respond quickly to the transmitting device.

[0590] In addition, it should be noted that the above-mentioned process of triggering the receiving device to update the number of segmented signals of the UWB signal can be applied to other scenarios, that is, the triggering process can be independent. For example, there is no limit on the method used to determine the number of segmented signals of the UWB signal before the change request. When the receiving device needs to change the number of segmented signals of the UWB signal, the triggering process can be used to trigger the update of the number of segmented signals of the UWB signal.

[0591] Exemplarily, the method for determining the number of segmented signals of the UWB signal before the change request may be the above-mentioned method based on the UWB test signal in the ranging control phase, or may be other existing or future methods for determining the number of segmented signals of the UWB signal.

[0592] For ease of understanding, combined Fig.12 (e) to (g) in the figure introduce in detail the process of triggering the receiving device to update the number of segmented signals of the UWB signal.

[0593] Possibility 1: During the measurement result reporting phase of the current measurement round, the receiving end device sends a change request message to the transmitting end device to trigger an update of the number of segment signals of the UWB signal of the next measurement round.

[0594] In a first possibility, the change request message may be carried in a report message related to the ranging result. Fig.12 As shown in (e).

[0595] Possibility 2: During the measurement phase of the current measurement round, the receiving device sends a change request message to the transmitting device to trigger an update of the number of segmented signals of the UWB signal for the next measurement round. Fig.12 As shown in (f) and (g).

[0596] Depend on Fig.12 As shown in (f) and (g), the change request message and the UWB signal sent by the receiving device to the transmitting device can be exchanged in the order of sending time slots.

[0597] Above Fig.12In the process of triggering the update of the number of segmented signals of the UWB signal shown in (e) to (g), the receiving device is the responding device and the sending device is the initiating device; or, the receiving device is the initiating device and the sending device is the responding device. In addition, Fig.12 In the cases shown in (e) to (g) in FIG. 1 , the sending device is the control device, and the control device can also be a third party or a receiving device. The process is the same as Fig.12 (e) to (g) are similar and will not be repeated here.

[0598] It should be noted that the above-mentioned process of triggering the update of the number of segment signals of the UWB signal can be used in combination with the above-mentioned process of determining the number of segment signals of the UWB signal.

[0599] For example, for Figure 6 or Figure 8 In the case shown, the transmitting end device receives a change request message from the receiving end device during the measurement result reporting phase and / or measurement phase of the previous measurement round before the number of segmented signals of the UWB signal is determined in the current measurement round. For example, before step S611, the transmitting end device receives a change request message from the receiving end device; or,

[0600] After determining the number of segmented signals of the UWB signal in the current measurement round, the receiving end device sends a change request message to the transmitting end device during the measurement result reporting phase and / or measurement phase of the current measurement round, in order to update the number of segmented signals of the UWB signal transmitted in the next measurement round. For example, after step S632, the receiving end device sends a change request message to the transmitting end device.

[0601] It should be understood that the sequence numbers of the above processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
