Both of these Chinese patent applications are hereby incorporated by reference in their entirety.

Background Art

[0003] Ultra-wideband (UWB) technology is a wireless communication (such as ranging or sensing) technology that uses nanosecond-level non-sinusoidal narrow impulse signals. Due to its narrow impulse and extremely low spectral density of radiation, UWB systems have advantages such as strong multipath resolution, low power consumption, and high confidentiality.

[0004] In a ranging or sensing scenario, the accuracy of the measurement or sensing result is highly related to the signal bandwidth. A larger signal bandwidth indicates higher accuracy of the result obtained through sensing or ranging. Therefore, reference signals for ranging or sensing can be received and transmitted by using a UWB system, and it can be considered that another reference signal and / or data are transmitted based on a narrowband protocol. This processing method can be understood as narrowband protocol-assisted UWB ranging or sensing.

[0005] In the current narrowband protocol-assisted UWB ranging method, in the ranging control phase, the responder roughly estimates the number of fragment signals of the UWB ranging signal that need to be used in the ranging phase in the current UWB ranging round based on the power intensity of the narrowband signal received from the initiator. This may cause confusion in the parameter configuration of the initiator in the ranging phase and reduce the system efficiency. Therefore, how to improve the performance of the narrowband protocol-assisted UWB ranging or detection method has become an urgent issue to be solved.

Summary of the Invention

[0006] Embodiments of the present application provide a signaling transmission method. In a narrowband protocol-assisted UWB data measurement scenario, in order to reduce the possibility of misconfiguring the number of blocks of the UWB ranging signal, the number of blocks of the UWB ranging signal is determined based on the UWB test signal.

[0007] According to a first aspect, a signaling transmission method is provided. The method may be executed by a receiving device, or may be executed by a component (e.g., a chip or a circuit) of the receiving device. This is not limited. For ease of explanation, an example where the method is executed by a receiving device is used for explanation below. It should be understood that the receiving device may be a measurement responder device or a measurement initiator device.

[0008] The signaling transmission method includes: a step in which a receiving device receives a first ultra-wideband UWB signal from a transmitting device; and a step in which the receiving device transmits first indication information to the transmitting device, where the first indication information indicates a first number of fragment signals of a second UWB signal; and the first indication information is determined based on the first UWB signal.

[0009] Based on the technical solution, instead of determining the number of fragment signals of the UWB signal based on the narrowband signal, the receiving device determines the number of fragment signals of the second UWB signal to be transmitted based on the received first UWB signal. Compared with the solution of estimating the number of fragment signals of the UWB signal based on the narrowband signal, this technical solution has a more accurate number, reduces the possibility of incorrectly configuring the number of fragment signals of the UWB signal, and avoids or reduces the possibility of reducing system efficiency.

[0017] In connection with the first aspect, in some implementations of the first aspect, the method further includes: a receiving device receiving second indication information from the transmitting device, where the second indication information indicates a second number of fragment signals of the second UWB signal, and the second indication information is determined based on the first indication information.

[0018] Based on the technical solution, the transmitting device and the receiving device may negotiate the appropriate number of fragment signals of the UWB signal, thereby improving the accuracy of the solution.

[0020] Based on the technical solution, the transmitting device and the receiving device may exchange UWB signals of their respective UWB receivers. As a result, the transmitting device determines the number of block signals of the second UWB signal by comprehensively considering the quality of the received UWB signals of the respective UWB receivers of the transmitting device and the receiving device. Thereby, the accuracy of the solution is improved.

Mode for Carrying Out the Invention

[0148] Hereinafter, with reference to the accompanying drawings, the technical solution of the present application will be described.

[0149] Embodiments of the present application are applicable to a wireless personal area network (WPAN) based on Ultra-WideBand (UWB) technology. Currently, the standard for WPAN is the Institute of Electrical and Electronics Engineers (IEEE) 802.15 series. WPAN may be used for communication between digital auxiliary devices within a small range, such as telephones, computers, and auxiliary devices, and the operating range of WPAN is usually within 10 m. Technologies that support wireless personal area networks include Bluetooth (Bluetooth), ZigBee (ZigBee), ultra-wideband, Infrared Data Association (IrDA) connection technology (infrared), and Home Radio Frequency (HomeRF) technology, etc. Various aspects of the present application can be extended to other networks using various standards or protocols, such as Wireless Local Area Network (WLAN), High Performance Radio LAN (HIPERLAN) (a wireless standard similar to the IEEE 802.11 standard mainly used in Europe), Wide Area Network (WAN), or other networks that are currently known or will be developed in the future, which can be easily understood by those skilled in the art. From the perspective of network configuration, WPAN is located at the bottom layer of the entire network architecture and is for wireless connection between devices within a small range, that is, for point-to-point short-distance connection, and can be regarded as a short-distance wireless communication network. Based on different application scenarios, WPAN is further classified into high rate (HR)-WPAN and low rate (LR)-WPAN. HR-WPAN can be used to support various high-speed multimedia applications, including high-quality audio and video distribution, multi-megabyte music, and image and document transmission, etc.LR-WPAN may be for general services in daily life.

[0150] In WPAN, devices can be classified into full - function devices (FFD) and reduced - function devices (RFD) based on the communication capabilities of these devices. FFD devices can communicate with each other, and FFD devices and RFD devices can communicate with each other. RFD devices cannot communicate directly with each other, can only communicate with FFD devices, or transfer data externally through one FFD device. The FFD device associated with an RFD is called the coordinator of the RFD. Also, a coordinator can control and associate multiple FFDs. A coordinator is also called a control node. There can be multiple coordinators in each ad - hoc network. RFD devices are mainly for simple control applications such as lighting switches and passive infrared sensors, transmit a small amount of data, and occupy a small number of transmission and communication resources. Therefore, the cost of RFD devices is low. A coordinator can also be called a Personal Area Network (PAN) coordinator. A PAN coordinator can be understood as one type of coordinator, and a PAN coordinator is also called a PAN central control node, etc. An FFD can function as a PAN coordinator or a coordinator, while an RFD cannot function as a PAN coordinator or a coordinator. A PAN coordinator is the main control node of the entire network, and each ad - hoc network can have only one PAN coordinator with member identification information management, link information management, and packet transfer functions. Optionally, the devices in the embodiments of the present application may be devices that support multiple WPAN standards such as 802.15.4a, 802.15.4z, and 802.15.4ab or later versions.

[0151] In an embodiment of the present application, the device may be a communication server, a router, a switch, a bridge, a computer, a mobile phone, a home smart device, an in-vehicle communication device, or the like.

[0152] In an embodiment of the present application, the device includes a hardware layer, an operating system layer operating on the hardware layer, and an application layer operating 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 referred to as main memory). The operating system may be any one or more types of computer operating systems that implement service processing through a process, such as a Linux (registered trademark) operating system, a Unix (registered trademark) operating system, an Android (registered trademark) operating system, an iOS (registered trademark) operating system, or a Windows (registered trademark) operating system. The application layer includes applications such as a browser, a contact, word processing software, and instant messaging software. In addition, on the condition that a program recording the code of the method provided in the embodiment of the present application can be operated to execute communication according to the method provided in the embodiment of the present application, the specific structure of the execution subject of the method provided in the embodiment of the present application is not particularly limited in the embodiment of the present application. For example, the method provided in the embodiment of the present application may be executed by an FFD or an RFD, or a functional module capable of calling and executing a program within the FFD or the RFD.

[0153] In addition, aspects or features of the present application can be implemented as a method, apparatus, or product using standard programming and / or engineering techniques. As used herein, the term "product" includes a computer program that can be accessed from any computer-readable component, carrier, or medium. For example, computer-readable media can include, but are not limited to, magnetic storage components (e.g., hard disks, floppy disks, or magnetic tape), optical disks (e.g., compact disc (CD), digital versatile disc (DVD)), smart cards, and flash storage components (e.g., erasable programmable read-only memory (EPROM)), cards, sticks, or key drives. Additionally, the various storage media described herein can represent one or more devices and / or other machine-readable media configured to store information. The term "machine-readable media" can include, but is not limited to, wireless channels and various other media capable of storing, containing, and / or carrying instructions and / or data.

[0154] Alternatively, the embodiments of the present application are further applicable to wireless local area network systems such as the internet of things (IoT) network or vehicle to everything (V2X). Naturally, the embodiments of the present application are further applicable to other possible communication systems, for example, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunications system (UMTS), worldwide interoperability for microwave access (WiMAX (registered trademark)) communication systems, 5th generation (5G) communication systems, and future 6th generation (6G) communication systems.

[0155] The foregoing communication systems to which the present application is applicable are merely examples for illustration, and the communication systems to which the present application is applicable are not limited thereto. This will be uniformly described here and will not be elaborated again below.

[0156] Figure 1 is a diagram of two application scenarios according to the present application. In the system 101 shown in (A) of Figure 1, a plurality of FFD devices and a plurality of RFD devices form a communication system having a star topology, and one FFD is a PAN controller. In a communication system having a star topology, the PAN controller performs data transmission with one or more other devices, that is, a one-to-many or many-to-one data transmission architecture can be established among the plurality of devices. In the system 102 shown in (B) of Figure 1, a plurality of FFD devices and one RFD device form a communication system having a peer-to-peer topology or a mesh topology, and one FFD is a PAN controller. In a communication system having a peer-to-peer topology, a many-to-many data transmission architecture can be established among the plurality of different devices.

[0157] It should be understood that (A) and (B) of Figure 1 are merely simplified diagrams for easy understanding and do not constitute limitations regarding the application scenarios of the present application. For example, the system 101 and / or the system 102 may further include another FFD and / or another RFD. In another example, the PAN coordinator within the system 101 may be a coordinator, and / or the PAN coordinator within the system 102 may be a coordinator.

[0158] To facilitate understanding of the technical solutions in the embodiments of the present application, some terms or concepts that may be used in the embodiments of the present application will first be briefly described.

[0159] 1. UWB Technology: UWB technology uses non-sinusoidal narrow impulse signals at the nanosecond level. Therefore, it is a wireless communication vehicle ranging / detection technology that occupies a wide spectrum range. Due to its narrow impulses of radiation and extremely low spectral density, UWB systems have advantages such as strong multipath resolution, low power consumption, and high confidentiality, which are useful for coexistence with other systems, thereby improving spectrum utilization and system capacity.

[0160] Since the Federal Communications Commission (FCC) approved the introduction of UWB technology into the civilian field in 2002, ultra-wideband wireless communication has become one of the popular physical layer technologies for short-distance and high-speed wireless networks. Many world-famous companies, research institutions, and standardization organizations are actively engaged in the research, development, and standardization of ultra-wideband wireless communication technology. The Institute of Electrical and Electronics Engineers (IEEE) has incorporated UWB technology into the IEEE 802 series of wireless standards and published IEEE 802.15.4a, which is a WPAN standard based on UWB technology, and its evolved version, IEEE 802.15.4z. Currently, 802.15.4ab, which is the next-generation WPAN standard based on UWB technology, is on the agenda.

[0161] UWB technology performs data transmission through the reception and transmission of nanosecond-level or sub-nanosecond-level and extremely narrow impulses, rather than carriers in conventional communication systems. Therefore, it has high requirements for the time synchronization of transceiver devices. In addition, due to the large communication bandwidth of UWB technology, these devices have high power consumption and complexity when signals are received and transmitted in ultra-wideband channels. Most UWB communication devices are battery-powered. The next-generation standard is expected to further reduce the power consumption of UWB systems. Therefore, all signals except ranging and detection reference signals are received and transmitted in a narrow-band signal support mode in narrow-band systems. This reduces the overall power consumption overhead.

[0162] 2. Power of UWB Signals: Due to the large bandwidth of the ultra-wideband system during operation, the FCC has imposed strict restrictions on the power spectral density of UWB signals in order to reduce interference to other narrowband devices. According to the Code of Federal Regulations (CFR), there are the following two rules.

[0163] Rule 1: The average value of the maximum power spectral density (PSD) of the UWB signal transmitted within 1 millisecond shall not exceed 41.3 dBm per megahertz.

[0164] Rule 2: The maximum power of the UWB signal transmitted in any 50 MHz bandwidth shall not exceed 1 milliwatt.

[0165] Rule 1 limits the total energy transmitted by UWB within 1 millisecond (for example, in the case of a 500 MHz bandwidth, it is 37 nJ). This energy is transmitted within a shorter time. As a result, the instantaneous power of the transmitted signal increases, the signal coverage expands, and the signal-to-noise ratio of the signal received on the receiving side increases. Based on this, in some scenarios where it is necessary to increase the transmission power, the transmitting side divides the UWB signal to be transmitted into multiple fragment signals (the time length of each fragment signal is less than 1 millisecond), and then transmits only one fragment signal per millisecond.

[0166] For easier understanding, with reference to FIG. 2, the UWB signal will be briefly described. FIG. 2 is a diagram of the UWB signal according to an embodiment of the present application.

[0167] It can be seen from FIG. 2 that the transmitting side divides the UWB signal to be transmitted into multiple fragment signals (for example, UWB fragment signal #1, UWB fragment signal #2, and UWB fragment signal #3 shown in FIG. 2). The time length of each fragment signal is less than 1 millisecond, and one of the fragment signals is transmitted per millisecond. The signal type of the fragment signal is also a UWB signal.

[0168] In addition, the "fragment signal" in the present application may also be referred to as "block signal", "short signal", "partial signal", "fragment" or "block", etc. The name of the fragment signal is not limited and can identify that the UWB signal is divided into a plurality of UWB signals. The time length of each of the plurality of UWB signals obtained after the division is less than 1 millisecond, and one UWB signal obtained after the division is transmitted at each millisecond. Optionally, the plurality of fragment signals obtained by dividing the UWB signal may be the same. For example, the plurality of fragment signals obtained by dividing the UWB signal are preambles having the same configuration. The same configuration of the preamble includes, but is not limited to, the preamble length and the sequence used by the preamble, etc.

[0169] It can be seen from the above that the transmission target UWB signal is divided into a plurality of fragment signals for fragment transmission. Thereby, the instantaneous power of the UWB signal can be increased, but the instantaneous power cannot be increased infinitely. Rule 2 actually limits the power increase multiple of UWB-based fragment transmission.

[0170] For example, in the present application, UWB-based fragment transmission may also be referred to as multi-millisecond (MMS) transmission.

[0171] 3. Impulse Radio Ultra-Wideband (IR-UWB) System: Due to the large bandwidth of the ultra-wideband system, the devices of the ultra-wideband system need to have ultra-high-speed data reception and transmission capabilities. However, the spectral efficiency of the IR-UWB system based on impulse transmission is low, and when the same information is transmitted, the power consumption overhead required by the IR-UWB solution means is much higher than that of another narrowband short-range protocol (for example, Bluetooth or ZigBee).

[0172] 4. Ranging or Detection: In a ranging or detection scenario, the accuracy of the measurement or detection result is related to the signal bandwidth. A larger signal bandwidth indicates higher accuracy of the result obtained through detection or ranging. Therefore, the reference signal for ranging or detection can be received and transmitted by using a UWB system, and another reference signal and / or data can be considered to be transmitted based on a narrowband protocol. This ensures ranging and detection accuracy and can also reduce power consumption. Detection in this application may be well understood as the lowest-layer detection technology in the Internet of Things technology architecture, which is the primary step for obtaining information and implementing object control in the Internet of Things. Ranging can be understood as the measurement of the distance between devices, including but not limited to the measurement of the distance between two objects in the Internet of Things.

[0173] For example, in this application, the UWB technical solution combining narrowband-assisted UWB and multi-millisecond transmission can also be referred to as Narrowband-assisted multi-millisecond Ultra-wideband (NBA-MMS UWB).

[0174] For ease of understanding, referring to FIG. 3, the ranging / positioning system to which the aforementioned ranging technology is applied will be briefly described. FIG. 3 is a diagram of the architecture of a ranging / positioning system according to an embodiment of this application. As shown in FIG. 3, the ranging / positioning system includes a plurality of devices (Device 1 and Device 2 shown in FIG. 3), which may be devices in the embodiments of this application. Each device includes at least a UWB module, and further, the device may further include a narrowband communication module. Any one of ranging, positioning, and communication can be executed between the UWB modules of Device 1 and Device 2. When these devices include narrowband communication modules, data transmission can be executed between the narrowband communication modules of Device 1 and Device 2 through a wireless link.

[0175] In this application, the UWB module can be understood as a device, chip, system, etc. that implements UWB wireless communication technology. Correspondingly, the narrowband communication module can be understood as a device, chip, system, etc. that implements narrowband communication technology (such as Wi-Fi (registered trademark), Bluetooth, or ZigBee (ZigBee protocol)). In one device, the UWB module and the narrowband communication module may be different devices or chips. Of course, the UWB module and the narrowband communication module can alternatively be integrated into one device or chip. Embodiments of this application do not limit the implementation of the UWB module and the narrowband communication module within this device. The UWB technology can enable the communication device to have high data throughput and enable device positioning to have high precision.

[0176] The device in this application may be a wireless communication chip, a wireless sensor or a wireless communication terminal, such as 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 supports Wi-Fi communication function. The user terminal may be various handheld devices, in-vehicle devices, wearable devices, Internet of Things (IoT) devices, or computing devices with wireless communication functions, or other processing devices connected to a wireless modem, various forms of user devices (user equipment, UE), mobile stations (MS), terminals, terminal devices, portable communication devices, handheld devices, portable computing devices, entertainment devices, game devices or systems, global positioning system devices, or any other suitable device configured to perform network communication via a wireless medium. In addition, this device may support the 802.15.4ab standard or the next-generation standard of 802.15.4ab. This device further supports multiple standards such as 802.15.4a, 802.15.4-2011, 802.15.4-2015, and 802.15.4z. This device further supports multiple wireless local area network (WLAN) standards of the 802.11 family, such as the next-generation versions of 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, and 802.11be.

[0177] 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 reliability level of the ranging signal. Specifically, the FoM field indicates the accuracy of estimating the arrival time of the ranging signal.

[0178] For example, the arrival time of the ranging signal is used to determine the ranging result. It can also be understood that the FoM field indicating the accuracy of estimating the arrival time of the ranging signal is used to evaluate the reliability level of the ranging result. In the present application, the FoM field may also be referred to as the ranging reliability level field and indicates the ranging reliability level.

[0179] Specifically, the ranging reliability level field is shown in Table 1 below. [Table 1: Ranging Reliability Level Field List]

Table 1

[0180] The meaning of the specific content of the "Reliability Level" field in Table 1 is shown in Table 2 below. [Table 2: Content of the Reliability Level Field]

Table 2

[0181] A higher reliability level value in Table 2 indicates that the current ranging result is more reliable, and "FoM None" in Table 2 indicates that the current ranging result is inaccurate or unusable.

[0182] 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 for each ranging round is a ranging slot. One ranging round is classified into three phases: a ranging control phase, a ranging phase, and a measurement report phase. FIG. 4 is a diagram of the phases of a UWB ranging round. In IEEE 802.15.4z, the ranging control phase includes one ranging slot, while in the currently discussed IEEE 802.15.4ab standard, it can be seen from FIG. 4 that the ranging control phase may include more than one ranging slot.

[0183] It should be noted that the signaling transmission method provided in this application is applicable not only to narrowband protocol-assisted UWB ranging, but also to narrowband protocol-assisted UWB detection or other measurement procedures. Therefore, in this application, the ranging control phase shown in FIG. 4 may be understood as a measurement control phase, the ranging phase may be understood as a measurement phase, and the measurement report phase may be understood as a measurement result report phase. For example, the signaling transmission method provided in this application is applicable to a narrowband protocol-assisted UWB detection procedure. The measurement control phase may be understood as a detection control phase, the measurement phase may be understood as a detection phase, and the measurement result report phase may be understood as a detection result report phase.

[0184] In addition, it should be further noted that the names of the different phases of the aforementioned single measurement round are merely examples and do not constitute any limitation regarding the protection scope of this application. For example, the measurement control phase may be understood as the phase for configuring the parameters required in the measurement round; in another example, the measurement phase may be understood as the phase for measurement; and in yet another example, the measurement result report phase may be understood as the phase for reporting the measurement results and may sometimes also be referred to as the end of the measurement phase.

[0185] For ease of understanding, the narrowband protocol-assisted UWB ranging method will be briefly described below with reference to FIG. 5. FIG. 5 is a diagram of the UWB ranging method. FIG. 5 includes an initiator and a responder. By way of non-limiting example, the initiator may be a device having a communication function in a WPAN (e.g., the FFD or RFD shown in FIG. 1). Similarly, the responder may be a device having a communication function in a WPAN (e.g., the FFD or RFD shown in FIG. 1).

[0186] In addition, the structure of the initiator and the structure of the responder may be the structure of device 1 or device 2 shown in FIG. 3. For example, the initiator and the responder each include a UWB module and a narrowband communication module.

[0187] It can be seen from FIG. 5 that narrowband (NB) signals are exchanged between the initiator and the responder to complete processes such as configuration and synchronization for UWB NBA-MMS ranging. For example, to perform a handshake, the initiator transmits a narrowband Poll signal, and the responder responds with a Resp signal. The information carried in the Poll signal includes one or more of, but is not limited to, ranging round-related parameter configuration, ranging signal preamble-related parameter configuration (such as preamble length and sequence used by the preamble), UWB packet type (SP0 to SP3), device role, and slot scheduling assignment, etc.

[0188] In the ranging control phase, the responder roughly estimates the number of fragment signals of the UWB ranging signal that need to be used in the ranging phase in the current UWB ranging round based on the power intensity of the NB signal received from the initiator (for example, when the power intensity of the NB signal is high, the signal-to-noise ratio (SNR) is high, and the signal quality is good, it is determined that a small number of fragment signals are used; or when the power intensity of the NB signal is low, the SNR is low, and the signal quality is low, it is determined that a large number of fragment signals are used), and feeds back the roughly estimated number of fragment signals of the UWB ranging signal to the initiator. The initiator determines the number of fragment signals of the UWB ranging signal required in the ranging phase based on the number of fragment signals fed back by the responder.

[0189] Specifically, after receiving the response frame, the initiator, together with the responder, performs round-trip time measurement in the form of fragment transmission on the UWB channel. After the measurement is completed, the responder uses a narrowband system to send the measurement result (report) to the initiator.

[0190] In the above, the scenario to which the embodiments of the present application are applied has been described with reference to FIG. 1. Further, the basic concept in the present application has been briefly described, and the UWB ranging method has been briefly described with reference to FIG. 5. This method has the following drawbacks.

[0191] The NB channel and the UWB channel have different bandwidths and signal waveforms. As a result, the conditions of the NB channel and the UWB channel will be significantly different, and the channel attenuation will also be different. Specifically, the UWB signal has an ultra-short impulse duration at the nanosecond level, high time resolution, and a very wide transmission bandwidth. In an indoor multipath environment, the UWB receiver can coherently increase the impulse energy received from each multipath component to provide the gain of reception via a single path. According to existing research, in an indoor multipath scenario, the level intensity value of the UWB received signal can vary from -5 dB to +5 dB with respect to the average level intensity value. Therefore, the possibility of deep fading of the UWB signal is low, and thus it can effectively withstand multipath fading.

[0192] In contrast, the NB signal is more likely to be affected by multipath signals. According to existing research, in an indoor multipath scenario, the level intensity of the NB received signal can vary from -20 dB to -30 dB with respect to the average value. Therefore, since the possibility of deep fading of the NB signal is high, it becomes difficult to withstand multipath fading.

[0193] In conclusion, in the UWB ranging method shown in FIG. 5, when the responder roughly estimates the number of fragment signals of the UWB ranging signal required in the UWB ranging phase based on the intensity of the NB signal, serious distortion occurs. As a result, the initiator misconfigures the parameters in the ranging phase, reducing the system efficiency. For example, the initiator may erroneously configure a large number of fragment signals of the UWB ranging signal in the ranging phase. This results in an overly long ranging time, affecting the access of another ranging user and the implementation of the ranging task, prolonging the system delay, and reducing the system efficiency. In addition, if the configuration of the number of fragment signals of the UWB signal is inaccurate, the receiving / transmitting device cannot effectively enter the sleep state, affecting the operating duration of the receiving / transmitting device. Therefore, the configuration of the on period of the receiver of the receiving / transmitting device may become inappropriate, and furthermore, the power consumption may become excessively high. To solve the problems in the aforementioned UWB ranging method, the present application provides a signaling transmission method. The number of fragment signals of the UWB signal transmitted in the measurement phase is determined based on the UWB signal transmitted in the control phase. This improves the accuracy of determining the number of fragment signals of the UWB signal. Hereinafter, with reference to the accompanying drawings, the signaling transmission method provided in the present application will be described in detail.

[0194] In order to execute communication according to the method provided in the embodiment of the present application, on the condition that a program recording the code of the method provided in the embodiment of the present application can be executed, the specific structure of the execution subject of the method provided in the embodiment of the present application is not particularly limited in the following embodiments. For example, the method provided in the embodiment of the present application can be executed by a transceiver device or a functional module within the transceiver device that can call and execute the program.

[0195] The following description is provided to facilitate the understanding of the embodiments of the present application.

[0196] First, in the present application, "indicating" may include "directly indicating" and "indirectly indicating". When one piece of information is described as indicating A, this information may directly indicate A or indirectly indicate A, but this does not indicate that the information surely conveys A.

[0197] The information indicated by this information is referred to as the information to be indicated. In a specific implementation process, the information to be indicated can be indicated in a plurality of ways, for example, but not limited to, the information to be indicated, for example, the information to be indicated or the index of the information to be indicated can be directly indicated. Alternatively, the information to be indicated may be indirectly indicated by indicating other information, and there is a corresponding relationship between the other information and the information to be indicated. Alternatively, only a part of the information to be indicated may be indicated, and the other parts of the information to be indicated are known or pre-agreed. For example, in order to reduce the indication overhead to a certain extent, specific information can alternatively be indicated in a pre-agreed (for example, defined in a protocol) arrangement sequence of a plurality of information. In addition, in order to reduce the indication overhead caused by separately indicating the same information, the common part of all the information can be identified and indicated in a unified way.

[0198] Second, various numbers such as the first and second (for example, "♯1" and "♯2") indicated in the present application are only for ease of explanation and are used to distinguish objects, but are not intended to limit the scope of the embodiments of the present application. For example, these numbers are used to distinguish different channels, but are not for explaining a specific order or sequence. It should be understood that the objects so described are interchangeable in appropriate situations, and as a result, solution means other than the embodiments of the present application can be described.

[0199] Thirdly, in the present application, "predetermined" may include "predefined", for example, defined in a protocol. "Predefined" may be implemented in a manner of pre-storing corresponding codes, tables or other related information for indication in a device (including, for example, network elements). Specific implementations are not limited in the present application.

[0200] Fourthly, "storage" in the embodiments of the present application may mean being stored in one or more storages. The one or more storages may be separately arranged or integrated into an encoder or decoder, a processor or a communication device. Alternatively, a part of the one or more storages may be separately arranged and a part of the one or more storages may be integrated into a decoder, a processor or a communication device. The type of storage may be any form of storage medium. This is not limited in the present application.

[0201] Fifthly, the term "and / or" in this specification is merely for describing the corresponding relationship for related objects and indicates that three relationships may exist. For example, A and / or B may indicate three cases: only A exists, both A and B exist, and only B exists. In addition, the character " / " in this specification usually indicates an "or" relationship between related objects.

[0202] Sixthly, the "protocol" in the embodiments of the present application may be a standard protocol in the communication field and may include, for example, Wi-Fi protocol and related protocols applicable to future communication systems. This is not limited in the present application.

[0203] Without loss of generality, hereinafter, the signaling transmission method provided in the embodiments of the present application will be described in detail by taking the interaction between a transmission-side device and a reception-side device as an example. The transmission-side device may be abbreviated as the transmission side for short, and the reception-side device may be abbreviated as the reception side for short.

[0204] By way of example and not limitation, the transmitting device may be a device having a communication function in a WPAN, such as an FFD or an RFD. Similarly, the receiving device may also be a device having a communication function in a WPAN, such as an FFD or an RFD.

[0205] It should be understood that the specific types and names of the transmitting device and the receiving device are not limited in this application, provided that the transmitting device and the receiving device are communication devices capable of receiving and transmitting UWB signals and NB signals.

[0206] FIG. 6 is a schematic flowchart of a signaling transmission method according to an embodiment of the present application. This method includes the following steps.

[0207] S610: The transmitting device transmits a first UWB signal to the receiving device, or the receiving device receives a first UWB signal from the transmitting device.

[0208] Specifically, the transmitting device transmits a first UWB signal to the receiving device in the control phase of the first round. The first round may be any measurement round in the measurement procedure, and the initial configuration of the measurement round is completed in the control phase. The measurement includes a measurement process such as ranging or detection performed based on the UWB signal. For example, the first round is an arbitrary ranging round; or, in another example, the first round is an arbitrary detection round.

[0209] For example, the receiving device receives a first UWB signal from the transmitting device in the ranging control phase, and at least one ranging slot is required by the transmitting device to transmit the first UWB signal. In this embodiment, the ranging control phase may include more than one ranging slot, and at least one of the more than one ranging slots is for transmitting the first UWB signal.

[0210] In this embodiment, the first UWB signal is used to determine first indication information, and the first indication information indicates a first number of fragment signals of the second UWB signal. The fragment signals of the second UWB signal can be understood as fragment signals obtained by dividing the second UWB signal.

[0211] Optionally, the fragment signals included in the second UWB signal are the same. For example, the fragment signals included in the second UWB signal are preambles having the same configuration. The same configuration of the preamble includes, but is not limited to, the preamble length and the sequence used by the preamble.

[0212] For ease 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 detection signal. The second UWB signal can be understood as a UWB signal used to implement measurements transmitted in the first round of measurement phase (e.g., ranging phase or detection phase).

[0213] It should be noted that the specific function of the second UWB signal is not limited in the embodiments of the present application. The second UWB signal may be a UWB signal for ranging, or may be a UWB signal for detection, or may be a UWB signal implementing another measurement function. Examples are not listed here.

[0214] In addition, the first number of fragment signals of the second UWB signal can be understood as follows, that is, when the second UWB signal is divided into a plurality of fragment signals (shown in Figure 2) in the transmission process. The time length of each fragment signal is less than 1 millisecond. Therefore, only one fragment signal is transmitted within each millisecond, and the number of the plurality of fragment signals is shown as the first number. For example, the fragment signals included in the plurality of fragment signals are the same. For example, the fragment signals included in the plurality of fragment signals are preambles having the same configuration. The same configuration of the preamble includes, but is not limited to, the preamble length, the sequence used by the preamble, etc.

[0215] Optionally, when the number of fragment signals of the second UWB signal expected by the transmitting device is different from the number of fragment signals of the second UWB signal expected by the receiving device, the transmitting device and the receiving device can negotiate to obtain an appropriate number of fragment signals of the second UWB signal for transmission. Hereinafter, the negotiation process will be described with reference to specific stages and will not be described again in detail here.

[0216] In a possible implementation, the first indication information implicitly indicates the number of fragment signals. For example, the first indication information is a fragment signal number index, and the fragment signal number index indicates the first number of fragment signals of the second UWB signal expected by the transmitting device. In 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 fragment signals of the second UWB signal expected by the transmitting device.

[0217] For example, the transmitting device and the receiving device obtain or locally store a second mapping relationship (for example, the transmitting device and the receiving device negotiate to determine and store the second mapping relationship, or the second mapping relationship is predefined in the protocol). The second mapping relationship is a mapping relationship between the fragment signal number index and the number of fragment signals. In other words, after receiving the fragment signal number index, the transmitting device can determine the number of fragment signals based on the second mapping relationship stored locally.

[0218] For example, the second mapping relationship is shown in Table 3a below. [Table 3a: Mapping relationship between fragment signal number index and number of fragment signals] [Table 3]

[0219] FNI indicates the fragment number index (Fragment Number Index, FNI).

[0220] In another example, the transmitting device and the receiving device obtain or locally store a third mapping relationship (for example, the transmitting device and the receiving device negotiate to determine and store the third mapping relationship, or the third mapping relationship is predefined in the protocol). The third mapping relationship is a mapping relationship between the FoM value and the number of fragment signals. In other words, after receiving the FoM value, the transmitting device can determine the number of fragment signals based on the third mapping relationship stored locally.

[0221] For example, the third mapping relationship is shown in Table 3b below. [Table 3b: Mapping relationship between FoM value and number of fragment signals] [Table 4]

[0222] In another possible implementation, the first indication information explicitly indicates the number of fragment signals. For example, the value of the first indication information is the number of fragment signals.

[0223] For example, when the value of the first indication information is 1, this indicates that the number of fragment signals is 1; when the value of the first indication information is 2, this indicates that the number of fragment signals is 2;..., when the value of the first indication information is N, this indicates that the number of fragment signals is N, where N is a positive integer.

[0224] It should be understood that the above is only an example for explaining the possible forms of the first indication information and does not constitute any limitation on the protection scope of this application. Other indication information that can indicate the number of fragment signals is included in the protection scope of this application. For example, the first indication information indicates the reliability level corresponding to the first UWB signal, and the reliability level corresponding to the first UWB signal is used to determine the first number of fragment signals of the second UWB signal expected by the transmitting device. For the sake of easy explanation, hereinafter, an example in which the first indication information is an index of the number of fragment signals for explanation is used.

[0225] It can be understood from the above that the first UWB signal is used to determine the first indication information, and the receiving device can determine the first indication information based on the first UWB signal after receiving the first UWB signal. Optionally, the procedure of the method shown in FIG. 6 further includes the following steps.

[0226] S620: The receiving device determines the first indication information based on the first UWB signal.

[0227] Specifically, the receiving device determining the first indication information based on the first UWB signal includes the following steps.

[0228] Step 1: The receiving device determines a reliability level corresponding to the first UWB signal based on the quality of the first UWB signal.

[0229] For example, if the quality of the first UWB signal is good, it is determined or estimated that the reliability level corresponding to the first UWB signal is high, and optionally, the corresponding FoM value is large; or if the quality of the first UWB signal is low, it is estimated that the reliability level corresponding to the first UWB signal is low, and optionally, the corresponding FoM value is small.

[0230] It should be understood that in this embodiment, there is no limitation on how to determine the reliability level corresponding to the first UWB signal based on the quality of the first UWB signal. For details, refer to the description of the step of determining the reliability level corresponding to the model in the current related technology based on signal quality. Details will not be described again here.

[0231] Furthermore, after the reliability level corresponding to the first UWB signal is determined, Step 2 is executed.

[0232] Step 2: The receiving device determines the first indication information based on the reliability level corresponding to the first UWB signal.

[0233] For example, there is a mapping relationship (referred to as the first mapping relationship for easy distinction) between the reliability level and the number of fragment signals of the second UWB signal. The receiving device may determine the number of fragment signals of the second UWB signal based on the reliability level and the first mapping relationship in order to determine the first indication information. The first mapping relationship is the mapping relationship between the reliability level and the number of fragment signals.

[0234] For example, the first mapping relationship is shown in Table 4a and Table 4b below. [Table 4a: Example 1 of the mapping relationship between the reliability level and the number of fragment signals]

Table 5

[0235] Table 4a and Table 4b show possible forms of the first mapping relationship by way of examples, and it should be noted that they do not constitute any limitation on the protection scope of the present application. The first mapping relationship may alternatively be in another form that can show the relationship between the reliability level and the number of fragment signals. For example, Table 4a and Table 4b include two columns of the reliability level and the number of fragment signals, and the reliability level index and FNI are optional. Here, the examples will not be re-explained one by one.

[0236] It can be seen from Table 4a and Table 4b that a higher reliability level corresponding to the first UWB signal indicates a higher credibility level of the estimated arrival time of the signal transmitted by the device in the UWB system, and thus, a smaller number of fragment signals estimated accordingly for the UWB signal transmitted in the UWB system.

[0237] For example, in order to enable the receiving device to recognize the relevant configuration of the first UWB signal, optionally, the procedure of the method shown in FIG. 6 further includes the following steps.

[0238] S611: The transmitting device transmits the first configuration information to the receiving device, or the receiving device receives the first configuration information from the transmitting device.

[0239] The first configuration information indicates the configuration of the first UWB signal.

[0240] For example, the first configuration information can be transmitted through a narrowband signal. For example, the first configuration information is carried in the first narrowband signal. Specifically, in the present embodiment, in order to improve the accuracy of receiving the first UWB signal, before receiving the first UWB signal, the receiving device receives the first narrowband signal from the transmitting device, and the first narrowband signal includes the first configuration information, and the first configuration information indicates the configuration of the first UWB signal.

[0241] For example, when the transmitting device is a ranging initiator device, the receiving device is a ranging responder device, and the polling signal transmitted from the initiator to the responder in the ranging control phase includes the first configuration information, and the first configuration information indicates the configuration of the first UWB signal. For example, the polling signal includes, but is not limited to, information indicating the preamble length of the first UWB signal, information indicating the sequence used by the preamble of the first UWB signal, etc. In a possible implementation, the first UWB signal is a UWB signal transmitted in the control phase of the first measurement round in the measurement process, and the first configuration information can be carried in a narrowband signal transmitted in the control phase (for example, a polling signal, a response signal, or a newly added narrowband signal transmitted in the control phase of the first measurement round).

[0242] In another possible implementation, when the first UWB signal is a UWB signal transmitted in the control phase of measurement round #1 after the first measurement round in the measurement process, the first configuration information may not need to be transmitted. For example, the configuration of the UWB signal transmitted in the previous measurement round may be used as the related configuration of the first UWB signal; or the first configuration information may be carried in the polling signal transmitted in the control phase of measurement round #1; or the first configuration information may be transmitted before the polling signal is transmitted in the control phase of measurement round #1.

[0243] Furthermore, after determining the first indication information, the receiving device transmits the first indication information to the transmitting device. As a result, the transmitting device recognizes the first number of fragment signals of the second UWB signal determined by the receiving device. The procedure of the method shown in FIG. 6 further includes the following steps.

[0244] S630: The receiving device transmits the first indication information to the transmitting device, or the transmitting device receives the first indication information from the receiving device.

[0245] For example, the first indication information is transmitted through a narrow band. In other words, the first indication information may be a narrow band signal. In a possible implementation, in this embodiment, the receiving device may include the first indication information in a predefined first information element and transmit a predefined first information element carrying the first indication information to the transmitting device (for example, the first information element is transmitted through a narrow band). The predefined first information element is an information element that can be analyzed by the transmitting device. The first information element further includes a first address size specifier field and / or a first address field. The first address size specifier field indicates the address type of the device that receives the first information element, and the first address field indicates the address of the device that receives the first information element.

[0246] For example, the first information element is a predefined FoM-based UWB fragment number estimation information element (FFNE IE). The design of FFNE IE is shown in Table 5. [Table 5: FFNE IE]

Table 7

[0247] The address size specifier field indicates the address type of the device that receives the FFNE IE. The address size specifier field may have another name, provided that the address type of the device that receives the first information element can be indicated. This is not limited in the present application. The address type may include one or more of a short address (i.e., the address length is 2 octets) and a long address (i.e., the address length is 8 octets). Optionally, the indication rule is 00 indicates that there is no address, i.e., 0 octets; 01 indicates that it is reserved; 10 indicates a short address, i.e., 2 octets corresponding to 16 bits; and 11 indicates a long address, i.e., 8 octets corresponding to 64 bits which is consistent with that in the previous generation UWB standard IEEE802.15.4z.

[0248] If the value of the address size specifier field in the FFNE IE is 00 and the address field is 0, this indicates that no address information is included. It can be understood that the receiving device broadcasts the FFNE IE. In other words, after generating the first information element, the receiving device may broadcast the first information element.

[0249] In another possible implementation, the receiving device may directly send the first indication information to the transmitting device, and the first indication information does not need to be carried in the first information element.

[0250] 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.

[0251] For example, the newly added FFNE IE can be identified and processed by a device that needs to execute a ranging or detection function. In a possible implementation, the corresponding method for identifying and processing the newly added FFNE IE is similar to the method for identifying and processing nested IEs (e.g., RDM IE) defined in the existing protocol 802.15.4z. For details, refer to the method for identifying and processing nested IEs in the existing protocol 802.15.4z.

[0252] For example, the protocol upper layer of the transmitting device constructs the FFNE IE and transfers the FFNE IE to the MAC layer of the transmitting device.

[0253] In another example, the MAC layer of the receiving device transfers the received FFNE IE to the protocol upper layer of the receiving device, and the protocol upper layer executes identification information processing on the FFNE IE.

[0254] In a possible implementation, the newly added FFNE IE can be transferred in a narrowband frequency band.

[0255] In another possible implementation, the newly added FFNE IE can alternatively be transferred in the UWB frequency band.

[0256] For ease of understanding, the newly added FFNE IE will be described in detail below with reference to Table 6.

[0257] Table 6 is an expansion and extension of Tables 7 to 18 in the existing 802.15.4z protocol. For the sake of brevity, the existing definitions in Tables 7 to 18 in this protocol are not reflected in Table 6. Specifically, it can be seen from Table 6 below that the newly added FFNE IE is added to the nested IE list defined in Tables 7 to 18 in the existing 802.15.4z protocol and can be used as a newly added IE in the 802.15.4ab protocol or later versions of the protocol. Specifically, the reserved Sub-ID value within the nested IE list defined in Tables 7 to 18 in the existing 802.15.4z protocol can indicate the newly added FFNE IE. [Table 6]

Table 8

[0258] Table 6 may be any one or more values from 0x5d to 0x7f. Table 6 may be an expansion and extension of the nested IE list defined in Tables 7 to 18 in the existing 802.15.4z protocol. X in Table 6 indicates that the FFNE IE is an IE of the data type.

[0259] Optionally, a message that carries the first indication information may be referred to as a UWB block number feedback message, and the UWB block number feedback message is a narrowband signal. In a possible implementation, a response (Resp) message of a receiving device for a polling message and a UWB block number feedback message fed back by the receiving device to a transmitting device may be included in the same response message. That is, the receiving device does not have to respond immediately after receiving the polling message, but after receiving the first UWB signal, uses one message to determine the first number of fragment signals of the second UWB signal, and thus responds to both the polling message and the UWB test block. This is applicable to scenarios where a high-speed bidirectional narrowband handshake connection is not required between the transmitting device and the receiving device.

[0260] For example, in a ranging slot after the transmitting device and the receiving device have each completed a Poll start and a Resp, the transmitting device transmits a UWB (e.g., the first UWB signal) to the receiving device for test (training) purposes. In other words, the Resp message of the receiving device and the UWB block number feedback message fed back by the receiving device to the initiator are two different messages. That is, the receiving device may respond to the polling message after receiving the polling message, and then, after receiving the first UWB signal and determining the first number of fragment signals of the second UWB signal, transmit the first indication information. This is applicable to scenarios where a high-speed bidirectional handshake connection needs to be executed between the initiator and the responder.

[0261] The above description merely explains how the receiving device transmits the first indication information to the transmitting device by using an example, and it should be understood that it does not constitute any limitation on the protection scope of the present application. In this embodiment, on the condition that the first indication information can be transmitted to the transmitting device, how the receiving device transmits the first indication information to the transmitting side is not limited.

[0262] Optionally, after receiving the first indication information, the transmitting device can recognize the first number of the fragment signals of the second UWB signal expected by the receiving device. Alternatively, the transmitting device may notify the receiving device of the second number of the fragment signals of the second UWB signal expected by the transmitting device by using the second indication information, or the transmitting device may notify the receiving device of the fourth number of the fragment signals of the second UWB signal expected by the transmitting device by using the second indication information.

[0263] In this embodiment, the transmitting device determines the number of the fragment signals of the second UWB signal expected by the transmitting device in the following two ways.

[0264] Method 1: The transmitting device makes a determination based on the first number of the fragment signals of the second UWB signal indicated by the received first indication information.

[0265] In Method 1, the procedure of the method shown in FIG. 6 further includes the following steps.

[0266] S621: The transmitting device determines the second number of the fragment signals of the second UWB signal based on the first number of the fragment signals of the second UWB signal.

[0267] In a possible implementation, the second number is the same as the first number. The transmitting device agrees to transmit the second UWB signal based on the first number. In the measurement phase of the first round, the transmitting device executes a UWB measurement procedure based on the first number.

[0268] In this implementation, the transmitting device may notify the receiving device, by using the second indication information, that the UWB measurement procedure can be executed based on the first number; or, the transmitting device may not need to notify the receiving device; or, the transmitting device may notify the receiving device, by using the acknowledgement (ACK) information, that the UWB measurement procedure can be executed based on the first number.

[0269] In another possible implementation, the second number is different from the first number. For example, the reference factors that affect the determination of the second number by the transmitting device include, but are not limited to, the following.

[0270] (a) The first number feedback by these receiving devices when there are multiple receiving devices. For example, when the first numbers feedback by multiple receiving devices are different, the transmitting device uses the largest first number as the second number.

[0271] For example, when there are multiple transmitting devices, for the method of determining the second number of the fragment signals of the second UWB signal by each transmitting device, refer to the aforementioned case where one transmitting device corresponds to multiple receiving devices. In other words, the case where multiple transmitting devices correspond to multiple receiving devices can be understood as multiple cases where one transmitting device corresponds to multiple receiving devices. Details will not be elaborated here again.

[0272] (b) The reliability level history information of the UWB signals in the previous multiple measurement rounds

[0273] Method 2: When there is a large difference between the noise levels of the UWB receivers of the transmitting device and the receiving device, the quality of the UWB received signals of the transmitting device and the receiving device needs to be considered together to determine the final number of UWB signals.

[0274] Method 2: The procedure of the method shown in FIG. 6 further includes the following steps.

[0275] S622: The receiving device transmits a fifth UWB signal to the transmitting device, or the transmitting device receives a fifth UWB signal from the receiving device.

[0276] Similar to the function of the first UWB signal transmitted from the transmitting device to the receiving device in S610, the fifth UWB signal is used by the transmitting device to estimate the number of fragment signals of the second UWB signal transmitted in the measurement phase (e.g., the ranging phase or the detection phase) for measurement.

[0277] For example, the fifth UWB signal may also be referred to as a UWB test signal.

[0278] In a possible implementation, the first indication information fed back from the receiving device to the transmitting device and the transmission slot sequence of the fifth UWB signal initiated by the receiving device to the transmitting device are not limited.

[0279] For example, the receiving device may first transmit the fifth UWB signal to the transmitting device and then transmit the first indication information to the transmitting device. This is applicable to scenarios where the receiving device needs more time to process the first UWB signal from the transmitting device.

[0280] In another example, the receiving device may first transmit the first indication information to the transmitting device and then transmit the fifth UWB signal to the transmitting device.

[0281] For example, when the receiving device feeds back a response (Resp) message to the transmitting device after transmitting the fifth UWB signal, the Resp message not only includes a response to the polling, but also includes first indication information that needs to be fed back to the transmitting device. It can be understood that the Resp message fed back by the receiving device to the initiator and the UWB block number feedback message are combined.

[0282] Optionally, in Method 2, since UWB test signals need to be exchanged between the transmitting device and the receiving device, the polling signal can be used to schedule and indicate the transmission order of the UWB test signal and the narrowband signal between the transmitting device and the receiving device in the ranging control phase.

[0283] For example, the polling signal indicates the slots occupied for transmitting the first UWB signal, the first indication information, the fifth UWB signal, and the following second indication information.

[0284] S623: The transmitting device determines the fourth number of fragment signals of the second UWB signal based on the first indication information and / or the fifth UWB signal.

[0285] For example, in Method 2, the transmitting device may determine the number of fragment signals of the second UWB signal transmitted in the measurement phase based on the narrowband signal (e.g., the first indication information) responded by the receiving device and / or the broadband signal (e.g., the fifth UWB signal) received.

[0286] For example, the transmitting device determines the number of fragment signals of the second UWB signal based on the first indication information received. This is the same as in step S621, and for details, it will not be described again here.

[0287] In another example, the transmitting device determines the number of fragment signals of the second UWB signal transmitted in the measurement phase based on the received broadband signal (e.g., the fifth UWB signal). For example, the fifth UWB signal is used to determine the fifth number of fragment signals of the second UWB signal, and the transmitting device determines that the number of fragment signals of the second UWB signal is greater than or equal to the fifth number.

[0288] In another example, the transmitting device determines the number of fragment signals of the second UWB signal transmitted in the measurement phase based on the received first indication information and the received broadband signal (e.g., the fifth UWB signal).

[0289] In a possible implementation, the fifth UWB signal is used to determine the fifth number of fragment signals of the second UWB signal. Specifically, in Method 2, the transmitting device refers to the first number of fragment signals of the second UWB signal indicated by the first indication information and the fifth number of fragment signals of the second UWB signal determined by the transmitting device based on the fifth UWB signal, and can finally determine the fourth number of fragment signals of the second UWB signal transmitted in the measurement phase (e.g., the ranging phase or the detection phase) for measurement.

[0290] For example, the transmitting device uses the larger value of the first number of the fragment signals of the second UWB signal and the fifth number of the fragment signals of the second UWB signal as the fourth number of the fragment signals of the second UWB signal; or, the transmitting device uses the average value of the first number of the fragment signals of the second UWB signal and the fifth number of the fragment signals of the second UWB signal as the fourth number of the fragment signals of the second UWB signal. In this embodiment, in the procedure of determining the fourth number of the fragment signals of the second UWB signal, it should be understood that how the transmitting device determines the fourth number of the fragment signals of the second UWB signal based on the first number of the fragment signals of the second UWB signal and the fifth number of the fragment signals of the second UWB signal is not limited, provided that the transmitting device considers the received first indication information and / or the fifth UWB signal. The transmitting device can notify the receiving device of the number of the fragment signals of the second UWB signal expected by the transmitting device by using the second indication information. The procedure of the method shown in FIG. 6 further includes the following steps.

[0291] S631: The transmitting device transmits the second indication information to the receiving device, or the receiving device receives the second indication information from the transmitting device.

[0292] Specifically, the second indication information indicates the number of the fragment signals of the second UWB signal transmitted in the measurement phase of the first round.

[0293] Corresponding to Method 1, the second indication information indicates the second number of the fragment signals of the second UWB signal; or, corresponding to Method 2, the second indication information indicates the fourth number of the fragment signals of the second UWB signal.

[0294] For example, the second indication information is transmitted through a narrow band. In other words, the second indication information may be a narrow band signal.

[0295] For example, the second indication information is carried in a notification message, and the notification message is used to schedule and indicate the transmission order of the fragment signals of the second UWB signal. The notification message may be a narrowband signal.

[0296] In addition, it should be noted that the message name is not limited in the embodiments of the present application. The message carrying the second indication information may be referred to as a notification message, or may have another name.

[0297] Optionally, the notification message may be included in a ranging control message (Ranging Control Message, RCM).

[0298] In a possible implementation, the RCM still uses the information elements defined in the previous generation IEEE 802.15.4z standard. The RCM is for the basic configuration of ranging measurements and scheduling indications, including scheduling and indication of the transmission order of ranging participating devices, configuration of ranging round parameters, configuration of ranging block structure parameters, and configuration of UWB channels and preambles for ranging, but is not limited thereto. In this implementation, some information elements in the existing RCM are reused to schedule and indicate the transmission order of the fragment signals of the UWB signal. Thereby, the backward compatibility of the solution can be improved.

[0299] In another possible implementation, the RCM may be a newly defined message including one or more information elements, and is for the basic configuration of the UWB signal and scheduling indications in the measurement phase.

[0300] The RCM in this embodiment is not subject to any limitation, and all messages that can be for the basic configuration of the fragment signals of the UWB signal and the scheduling indication in the measurement phase are included in the protection scope of this application. For example, the RCM in this embodiment may be a message including one or more information elements defined in an existing protocol and newly added information elements.

[0301] Similar to the foregoing first indication information, in a possible implementation of this embodiment, the second indication information may be carried by a transmission-side device in a predefined second information element and transmitted to a reception-side device. The second information element further includes a second address size specifier field and a second address field. The second address size specifier field indicates the address type of the device that receives the second information element, and the second address field indicates the address of the device that receives the second information element.

[0302] The format of the second information element is the same as that of the first information element, and for details, it will not be described again here.

[0303] For example, 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 type and length of the preamble may be different. The initiator may update the configuration of the preamble of the second UWB signal (and / or the fifth UWB signal), and this update includes but is not limited to updates such as the preamble length and the sequence used by the preamble. The update procedure may be carried by a narrowband signal NB. Optionally, the procedure of the method shown in FIG. 6 further includes the following steps.

[0304] S632: The transmission-side device transmits the second configuration information to the reception-side device, or the reception-side device receives the second configuration information from the transmission-side device.

[0305] The second configuration information indicates the configuration of the second UWB signal (and / or the fifth UWB signal). For example, the second configuration information may be transmitted through a narrowband signal. For example, the second configuration information is carried in the second narrowband signal.

[0306] In a possible implementation, the second narrowband signal and the second indication information are one narrowband signal. When the second narrowband signal carrying the second configuration information and the narrowband signal carrying the second indication information (for example, the UWB block number feedback message) are one narrowband signal, it can be understood that the signaling transmission time can be reduced and the effectiveness can be guaranteed. In the procedure shown in FIG. 6, the receiving device may be a ranging initiator device or a ranging responder device. Hereinafter, the procedure of the signaling transmission method provided in the present application when the receiving device plays different roles in the ranging process will be described with reference to specific examples.

[0307] Example 1: In the ranging procedure, the transmitting device is a ranging initiator device, the receiving device is a ranging responder device, and the initiator device is a control device. The control device can be understood as a device for determining relevant parameters in the ranging procedure.

[0308] FIG. 7(a) is a schematic flowchart corresponding to Example 1 and includes the following steps.

[0309] Step 1: The initiator device transmits a polling signal to the responder device.

[0310] Specifically, the polling signal includes, but is not limited to, the first ranging round related parameter configuration, the UWB signal preamble related parameter configuration (for example, the preamble length and the sequence used by the preamble), the UWB packet type (SP0 to SP3), the device role, and the scheduling assignment.

[0311] For example, the polling signal can be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0312] Step 2: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0313] Step 3: In the ranging control phase, the initiator device transmits the first UWB signal to the responder device.

[0314] For the related description of the first UWB signal, refer to the description of the first UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0315] Step 4: The responder device transmits the first indication information to the initiator device.

[0316] For the related description of the first indication information, refer to the description of the first indication information in the embodiment shown in FIG. 6. Details will not be described again here.

[0317] For example, the first indication information and the response signal in response to the polling signal can be combined for transmission. FIG. 7(a) does not show this case.

[0318] Step 5: The initiator device transmits the second indication information to the responder device.

[0319] For the related description of the second indication information, refer to the description of the second indication information in the embodiment shown in FIG. 6. Details will not be described again here.

[0320] Step 6: The initiator device transmits the second narrowband signal to the responder device.

[0321] For the description related to the second narrowband signal, refer to the description of the second narrowband signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0322] After steps 1 to 6, the initiator device and the responder device may transmit a UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal and the parameters constituted by using the second narrowband signal, in order to execute subsequent procedures of UWB ranging.

[0323] For example, the second indication information indicates that the number of fragment signals of the UWB ranging signal is 4.

[0324] Example 2: In the ranging procedure, the transmitting device is a ranging responder device, the receiving device is a ranging initiator device, and the transmitting device is a control device.

[0325] FIG. 7(b) is a schematic flowchart corresponding to Example 2, and includes the following steps.

[0326] Step 1: The initiator device transmits a polling signal to the responder device.

[0327] Specifically, the polling signal includes, but is not limited to, the first ranging round related parameter configuration, the UWB signal preamble related parameter configuration (for example, preamble length, and the sequence used by the preamble), the UWB packet type (SP0 to SP3), the device role, and the scheduling assignment.

[0328] For example, the polling signal may be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0329] Step 2: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0330] Step 3: In the ranging control phase, the responder device transmits a first UWB signal to the initiator device.

[0331] Step 4: The initiator device transmits first indication information to the responder device.

[0332] Step 5: The initiator device transmits a second narrowband signal to the responder device.

[0333] For the related description of the second narrowband signal, refer to the description of the second narrowband signal in the embodiment shown in FIG. 6. Details will not be described here again.

[0334] After Steps 1 to 5, the initiator device and the responder device can transmit a UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal and the parameters constituted by using the second narrowband signal, in order to execute subsequent procedures of UWB ranging.

[0335] For example, the first indication information indicates that the number of fragment signals of the UWB ranging signal is 4.

[0336] Example 3: The transmitting device is a ranging initiator device, the receiving device is a ranging responder device, and a control device is further included.

[0337] FIG. 7(c) is a schematic flowchart corresponding to Example 3, and includes the following steps.

[0338] Step 1: The initiator device (or the control device) transmits a polling signal to the responder device.

[0339] Specifically, the polling signal includes, but is not limited to, a first ranging round related parameter configuration, a UWB signal preamble related parameter configuration (e.g., preamble length and sequence used by the preamble), a UWB packet type (SP0 to SP3), a device role, and a scheduling assignment.

[0340] For example, the polling signal can be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0341] Step 2: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0342] Step 3: In the ranging control phase, the initiator device transmits a first UWB signal to the responder device.

[0343] Step 4: The responder device transmits first indication information to the control device.

[0344] For the related description of the first indication information, refer to the description of the first indication information in the embodiment shown in FIG. 6. Details will not be described again here.

[0345] For example, the first indication information and the response signal in response to the polling signal can be combined for transmission. FIG. 7(c) does not show this case.

[0346] Step 5: The control device transmits indication information #1 to the initiator device and the responder device.

[0347] The control device determines whether to transmit a second UWB signal based on the first number of blocks. When the control device determines to transmit a second UWB signal based on the first number of blocks, the control device transmits indication information #1 to the receiving device and the transmitting device. For example, information element #1 is broadcast, and information element #1 includes indication information #1. In another example, information element #2 and information element #3 are transmitted to the receiving device and the transmitting device respectively, and information element #2 and information element #3 each include indication information #1.

[0348] Step 6: The initiator device (or control device) transmits a second narrowband signal to the responder device.

[0349] After steps 1 to 6, the initiator device and the responder device may transmit a UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal and the parameters constituted by using the second narrowband signal, in order to execute subsequent procedures of UWB ranging.

[0350] For example, indication information #1 indicates that the number of fragment signals of the UWB ranging signal is 4.

[0351] Specifically, FIGS. 7(a) to 7(c) correspond to a case where the transmitting device determines the number of fragment signals of the second UWB signal based on the first indication information transmitted by the receiving device. It can be understood from the procedure shown in FIG. 6 that the transmitting device can further determine the number of fragment signals of the second UWB signal based on the first indication information transmitted by the receiving device and / or the UWB test signal transmitted by the receiving side. Hereinafter, in the ranging procedure, an example will be used in which the transmitting device is a ranging initiator device, the receiving device is a ranging responder device, and the initiator device is a control device, so that the transmitting device determines the number of fragment signals of the second UWB signal based on the first indication information transmitted by the receiving device and / or the UWB test signal transmitted by the receiving side. The specific procedure of the embodiment described in FIG. 6 will be described.

[0352] In a possible implementation, the following steps are included.

[0353] Step 1a: The initiator device transmits a polling signal to the responder device.

[0354] For example, the polling signal indicates the transmission order of the UWB test signal and the narrowband signal between the initiator device and the responder device in the ranging control phase.

[0355] For example, the polling signal can be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0356] Step 2a: In the ranging control phase, the initiator device transmits the first UWB signal to the responder device.

[0357] For the related description of the first UWB signal, refer to the description of the first UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0358] Step 3a: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0359] For example, the response (Resp) message of the responder device for the polling message and the UWB block number feedback message fed back by the responder device to the initiator device are included in the same response message.

[0360] Step 4a: The responder device transmits a fifth UWB signal to the initiator device.

[0361] For the related description of the fifth UWB signal, refer to the description of the fifth UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0362] Step 5a: The initiator device transmits second indication information to the responder device.

[0363] For the related description of the second indication information, refer to the description of the second indication information in the embodiment shown in FIG. 6. Details will not be described again here.

[0364] Step 6a: The initiator device transmits a second narrowband signal to the responder device.

[0365] For the related description of the second narrowband signal, refer to the description of the second narrowband signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0366] After steps 1a to 6a, the initiator device and the responder device can transmit UWB ranging signals based on the determined number of fragment signals of the UWB ranging signal and the parameters constituted by using the second narrowband signal in order to execute subsequent procedures of UWB ranging.

[0367] The aforementioned steps 1a to 6a are shown in FIG. 7(d). It should be noted that the order of the aforementioned steps 1a to 6a is not limited.

[0368] In another possible implementation, the following steps are included.

[0369] Step 1b: The initiator device sends a polling signal to the responder device.

[0370] For example, the polling signal indicates the transmission order of the UWB test signal and the narrowband signal between the initiator device and the responder device in the ranging control phase.

[0371] For example, the polling signal can be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0372] Step 2b: The responder device sends a response signal to the initiator device in response to the polling signal.

[0373] Step 3b: In the ranging control phase, the initiator device sends the first UWB signal to the responder device.

[0374] For the related description of the first UWB signal, refer to the description of the first UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0375] Step 4b: The responder device sends the first indication information to the initiator device.

[0376] In this implementation, the Resp message sent by the responder device and the UWB block number feedback message fed back by the responder device to the initiator device are not combined.

[0377] Step 5b: The responder device transmits a fifth UWB signal to the initiator device.

[0378] For the related description of the fifth UWB signal, refer to the description of the fifth UWB signal in the embodiment shown in FIG. 6. Details are not described here again.

[0379] Step 6b: The initiator device transmits second indication information to the responder device.

[0380] For the related description of the second indication information, refer to the description of the second indication information in the embodiment shown in FIG. 6. Details are not described here again.

[0381] Step 7b: The initiator device transmits a second narrowband signal to the responder device.

[0382] For the related description of the second narrowband signal, refer to the description of the second narrowband signal in the embodiment shown in FIG. 6. Details are not described here again.

[0383] The aforementioned steps 1b to 6b are shown in FIG. 7(e).

[0384] In another possible implementation, the following steps are included.

[0385] Step 1c: The initiator device transmits a polling signal to the responder device.

[0386] For example, the polling signal indicates the transmission order of UWB test signals and narrowband signals between the initiator device and the responder device in the ranging control phase.

[0387] For example, the polling signal can be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0388] Step 2c: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0389] Step 3c: In the ranging control phase, the initiator device transmits a first UWB signal to the responder device.

[0390] For the related description of the first UWB signal, refer to the description of the first UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0391] Step 4c: The responder device transmits a fifth UWB signal to the initiator device.

[0392] For the related description of the fifth UWB signal, refer to the description of the fifth UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0393] Step 5c: The responder device transmits first indication information to the initiator device.

[0394] In this implementation, the Resp message transmitted by the responder device and the UWB block number feedback message fed back by the responder device to the initiator device are not combined. In addition, the responder device first transmits the Resp message and then feeds back the UWB block number feedback message. This is applicable to scenarios where the responder device requires more time to process the UWB test signal from the initiator device.

[0395] Step 6c: The initiator device transmits second indication information to the responder device.

[0396] For the related description of the second indication information, refer to the description of the second indication information in the embodiment shown in FIG. 6. Details will not be described again here.

[0397] Step 7c: The initiator device transmits a second narrowband signal to the responder device.

[0398] For the related description of the second narrowband signal, refer to the description of the second narrowband signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0399] The above steps 1c to 6c are shown in FIG. 7(f).

[0400] In another possible implementation, the following steps are included.

[0401] Step 1d: The initiator device transmits a polling signal to the responder device.

[0402] For example, the polling signal indicates the transmission order of the UWB test signal and the narrowband signal between the initiator device and the responder device in the ranging control phase.

[0403] For example, the polling signal can be understood as the first narrowband signal in the embodiment shown in FIG. 6.

[0404] Step 2d: In the ranging control phase, the initiator device transmits a first UWB signal to the responder device.

[0405] For the related description of the first UWB signal, refer to the description of the first UWB signal in the embodiment shown in FIG. 6. Details will not be described again here.

[0406] Step 3d: The responder device transmits a fifth UWB signal to the initiator device.

[0407] Step 4d: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0408] For example, the responder device's response (Resp) message for the polling message and the UWB block number feedback message fed back by the responder device to the initiator device are included in the same response message.

[0409] For the related description of the fifth UWB signal, refer to the description of the fifth UWB signal in the embodiment shown in FIG. 6. Details are not described again here.

[0410] Step 5d: The initiator device transmits second indication information to the responder device.

[0411] For the related description of the second indication information, refer to the description of the second indication information in the embodiment shown in FIG. 6. Details are not described again here.

[0412] Step 6d: The initiator device transmits a second narrowband signal to the responder device.

[0413] For the related description of the second narrowband signal, refer to the description of the second narrowband signal in the embodiment shown in FIG. 6. Details are not described again here.

[0414] The aforementioned steps 1d to 6d are shown in FIG. 7(g).

[0415] Similarly, when the transmitting device determines the number of fragment signals of the second UWB signal based on the first indication information transmitted by the receiving device and / or the UWB test signal transmitted by the receiving side, in the ranging procedure, the case where the transmitting device is a ranging responder device, the receiving device is a ranging initiator device, and the transmitting device is a control device is the same as the case where the transmitting device is a ranging initiator device, the receiving device is a ranging responder device, and the initiator device is a control device in the ranging procedure. For example, in FIGS. 7(d) to 7(g), the device that transmits the first indication information and / or the first UWB signal is replaced by the initiator device, and the device that transmits the fifth UWB signal is replaced by the responder device. In this case, the case where the Resp message and the first indication information are combined for transmission does not occur.

[0416] In addition, FIGS. 7(d) to 7(g) show a case where the initiator device is a control device. When the responder device is a control device, the initiator device needs to return the fifth number of fragment signals of the UWB signal determined based on the fifth UWB signal to the responder device, and the responder device finally determines the number of fragment signals of the UWB signal based on the first UWB signal and the received information indicating the fifth number, and notifies the initiator device by using a notification message.

[0417] The foregoing embodiments have been described by way of example for a one-to-one case, that is, by using one initiator device and one responder device. It should be noted that the signaling transmission method shown in FIG. 6 can also be extended to one-to-many or many-to-many cases, that is, one initiator device and a plurality of responder devices, or a plurality of initiator devices and a plurality of responder devices.

[0418] For example, the one-to-many case is shown in FIG. 7(h).

[0419] The polling message in the ranging control phase can be used to schedule and indicate the transmission order of a plurality of UWB test signals and a plurality of narrowband signals between the initiator device and the plurality of responder devices in the ranging control phase.

[0420] For example, slots occupied by the initiator device to transmit UWB test signals and narrowband signals are shown, and slots occupied by the plurality of responder devices to transmit the plurality of UWB test signals and the plurality of narrowband signals are shown.

[0421] In a possible implementation, the initiator device may send a notification message in the ranging control phase to notify the number of fragment signals of the second UWB signal in the measurement phase.

[0422] Optionally, the notification message in the ranging control phase may alternatively be used to schedule and indicate the transmission order of the plurality of fragment signals of the second UWB signal between the initiator device and the plurality of responder devices in a subsequent measurement phase.

[0423] For example, the notification message indicates the slots occupied by the initiator device and the plurality of responder devices to transmit the fragment signals.

[0424] Hereinafter, how the initiator device determines the number of fragment signals of the second UWB signal transmitted in the measurement phase in a one-to-many case will be described using an example.

[0425] It is assumed that there are N responder devices, and the number of fragment signals generated by each responder device is F1, F2...F N in order.

[0426] In a case where the number of fragment signals of a second UWB signal is determined based on the number of fragment signals feedback by a responder device to a transmitting device:

[0427] The transmitting device, F1, F2... F N The maximum value in can be used as the number of fragment signals of the second UWB signal in the measurement phase.

[0428] In a case where the number of fragment signals of a second UWB signal is determined based on the number of fragment signals feedback by a responder device to a transmitting device and the number of fragment signals estimated by the transmitting device,

[0429] Corresponding to UWB test signals (e.g., a plurality of fifth UWB signals) transmitted by a plurality of responder devices, the transmitting device accordingly sets a plurality of numbers of fragment signals indicated as F N+1 , F N+2 ... F 2N A simple method for determining the final number of fragment signals of the second UWB signal is that the maximum number of fragment signals in F1, F2... F N and F N+1 , F N+2 ... F 2N is used as the number of fragment signals of the second UWB signal. That is, Number of fragment signals of the second UWB signal = max(F1, F2... F 2N ) is the case.

[0430] In a many-to-many case, for the method of determining the number of fragment signals of the second UWB signal by each initiator device, refer to the aforementioned one-to-many case. That is, the many-to-many case may be understood as a plurality of one-to-many cases, and the details will not be described again here.

[0431] In the embodiment shown in FIG. 6, it can be understood from the above that in the ranging control phase, the number of UWBs can be estimated based on the quality of the UWB test signal. Compared with the existing solution means where the estimation is performed based on the narrowband NB signal, this solution means is more accurate, reduces the possibility of misconfiguring the number of UWBs, and avoids or reduces the possibility of reducing system efficiency.

[0432] In addition, the embodiment shown in FIG. 6 can avoid or reduce the possibility that the on-period of the receiver of the receiving / transmitting device is inappropriately configured. Furthermore, it can avoid or reduce the possibility that the receiving / transmitting device cannot effectively sleep and thus power is consumed excessively fast. Moreover, it can avoid or reduce the possibility that the operating duration of the receiving / transmitting device is reduced.

[0433] In addition, the present application further provides another signaling transmission method to adjust the inappropriate number of UWBs to the appropriate number of UWBs within a time based on the actual measurement effect of the current ranging round. Thereby, a lot of time waste in subsequent continuous ranging processes is avoided and system efficiency is improved. Hereinafter, with reference to the accompanying drawings, the signaling transmission method will be described in detail.

[0434] Unless otherwise specified, the detailed description of some technical features in one embodiment can also be used to explain the corresponding technical features mentioned in another embodiment. For example, the specific description of the fragment signal of the UWB signal in the embodiment shown in FIG. 6 may be applied to an embodiment shown in FIG. 8, and the concept of the fragment signal does not need to be described in detail in the embodiment shown in FIG. 8. In another example in the embodiment shown in FIG. 6, the specific description of the step of determining the number of fragment signals of the UWB signal based on the reliability level of the UWB signal may be applicable to the embodiment shown in FIG. 8. Here, the examples will not be described again one by one.

[0435] FIG. 8 is a schematic flowchart of another signaling transmission method according to the present application. This method includes the following steps.

[0436] S810: The transmitting device determines third indication information based on at least one fragment signal of the fourth UWB signal.

[0437] The third indication information indicates the third number of fragment signals of the third UWB signal. The fourth UWB signal is a UWB signal transmitted in the current measurement round for measurement (e.g., detection or ranging). The UWB signal is divided into a plurality of fragment signals for transmission in the transmission process. The transmitting device is a device that receives the plurality of fragment signals.

[0438] In this embodiment, the transmitting device may determine the actual measurement effect of the current measurement round based on the quality of the received fragment signals, and may determine that the number of fragment signals of the current UWB signal is no longer appropriate, and the number of fragment signals of the UWB signal needs to be changed (or updated).

[0439] In a possible implementation, the transmitting device may determine the third indication information based on any fragment signal of the received fourth UWB signal.

[0440] For example, the transmitting device determines the third indication information based on the quality of any one of the received plurality of fragment signals. For the specific method of determining the number of fragment signals of the UWB signal to be transmitted based on the quality of the UWB signal, refer to the description of the "step of determining the first indication information based on the first UWB signal" in the embodiment shown in FIG. 6. Details will not be described again here.

[0441] In another possible implementation, the transmitting device may determine the third indication information based on a plurality of fragment signals of the received fourth UWB signal.

[0442] For example, the transmitting device determines the third indication information based on the average reliability level value of the received plurality of fragment signals.

[0443] The above is merely an example for explaining how to determine the third indication information based on the fragment signal, and it should be understood that it does not constitute any limitation regarding the protection scope of the present application.

[0444] S820: The transmitting device transmits the third indication information to the control device, or the control device receives the third indication information from the transmitting device.

[0445] For example, the third indication information is transmitted through a narrow band. In other words, the third indication information may be a narrow band signal.

[0446] Similar to the aforementioned first indication information, in a possible implementation of this embodiment, the third indication information may be carried by the transmitting device in a predefined third information element and transmitted to the control device. The third information element further includes a third address size specifier field and a third address field. The third address size specifier field indicates the address type of the device that receives the third information element, and the third address field indicates the address of the device that receives the third information element.

[0447] The format of the third information element is the same as that of the first information element, and for details, it will not be described again here.

[0448] Optionally, the transmitting device may transmit the second information to the control device to instruct to change the number of fragment signals of the third UWB signal. Optionally, the procedure of the method shown in FIG. 8 further includes the following steps.

[0449] S830: The transmitting device transmits the second information to the control device, or the control device receives the second information from the transmitting device.

[0450] The second information indicates that the number of fragment signals of the third UWB signal has been changed. For example, the second information is triggered by using a ranging change request information element (RCR IE).

[0451] In a possible implementation, the RCR IE still uses the information element defined in the previous generation IEEE 802.15.4z standard, and the RCR IE is for triggering ranging change requests including but not limited to changes in ranging round parameter configuration and ranging block structure. In this implementation, existing information elements are reused to indicate a change in the number of fragment signals of the UWB signal. Thereby, the backward compatibility of the solution can be improved.

[0452] In another possible implementation, the RCR IE may be a newly defined information element, indicating a change in the number of fragment signals of the UWB signal.

[0453] The RCR IE is not limited in this embodiment, and all information elements that can indicate a change in the number of fragment signals of the UWB signal are included in the protection scope of this application.

[0454] For example, the second information is transmitted through a narrow band, and the second information may be a narrow band signal.

[0455] Specifically, after receiving the third indication information, the control device can notify the transmitting device whether to agree to change the number of fragment signals of the third UWB signal by using the first information. The procedure of the method shown in FIG. 8 further includes the following steps.

[0456] S840: The control device transmits the first information to the transmitting device, or the transmitting device receives the first information from the control device.

[0457] The first information indicates whether it is agreed to change the number of fragment signals of the third UWB signal.

[0458] For example, the first information is transmitted through a narrow band, and the first information may be a narrow band signal.

[0459] In a possible implementation, the first information instructs to agree to update the number of fragments of the third UWB signal.

[0460] For example, the first information is an acknowledgement (ACK) information.

[0461] Optionally, in this implementation, after transmitting the acknowledgement information, the control device may further transmit fourth indication information for indicating the third number of fragment signals of the third UWB signal; or may further transmit fourth indication information for indicating the fourth number of fragment signals of the third UWB signal, where the fourth number is different from the third number.

[0462] In another example, the first information is the fourth indication information.

[0463] Specifically, in this implementation, the control device may transmit the fourth indication information to both the transmitting device and the receiving device, and as a result, the transmitting device and the receiving device can then transmit the UWB signal based on the changed number of fragment signals of the UWB signal. Optionally, the procedure of the method shown in FIG. 8 further includes the following steps.

[0464] S850: The control device transmits the fourth indication information to the transmitting device and the receiving device, or the transmitting device and the receiving device receive the fourth indication information from the control device.

[0465] For example, the fourth indication information is transmitted through a narrow band, and the fourth indication information may be a narrow band signal.

[0466] Similar to the aforementioned first indication information, in a possible implementation of this embodiment, the fourth indication information may be carried by the transmission-side device in a predefined fourth information element and transmitted to the control device. The fourth information element further includes a fourth address size specifier field and a fourth address field. The fourth address size specifier field indicates the address type of the device that receives the fourth information element, and the fourth address field indicates the address of the device that receives the fourth information element.

[0467] The format of the fourth information element is the same as that of the first information element, and for details, it will not be described again here.

[0468] For example, the control device broadcasts the fourth information element.

[0469] In another example, the control device transmits the fourth information element #1 to the transmission-side device, and the fourth address size specifier field and / or the fourth address field in the fourth information element #1 indicate that the device that receives the fourth information element #1 is the transmission-side device. The fourth information element #1 includes the fourth indication information. In addition, the control device transmits the fourth information element #2 to the receiving-side device, and the fourth address size specifier field and / or the fourth address field in the fourth information element #2 indicate that the device that receives the fourth information element #2 is the receiving-side device. The fourth information element #2 includes the fourth indication information.

[0470] In another possible implementation, the first information indicates that the number of fragment signals of the third UWB signal has not been agreed to be updated.

[0471] In this embodiment, cases where the control device agrees to update the number of fragment signals of the third UWB signal are mainly considered. It should be understood that cases where the control device does not agree to update the number of fragment signals of the third UWB signal are not described in this embodiment.

[0472] In a possible implementation, the transmitting device may send the first information and the third indication information to the control device in the measurement reporting phase of the first round. In this implementation, the control device may send the fourth indication information to the transmitting device and the receiving device in the measurement reporting phase of the first round; or the control device may send the fourth indication information to the transmitting device and the receiving device before the measurement phase of the second round.

[0473] In this implementation, after receiving the fourth indication information, the transmitting device and the receiving device may transmit the third UWB signal based on the changed number of fragment signals in the measurement phase of the second round. The second round is the measurement round after the first round. The inappropriate number of fragment signals can be adjusted to the appropriate number of fragment signals within a time based on the actual measurement effect of the current ranging round. Thereby, a lot of time waste in subsequent consecutive ranging processes is avoided, and the system efficiency is improved. In addition, this implementation can avoid or reduce the possibility that the on-period of the receiver of the receiving / transmitting device is inappropriately configured. Furthermore, it can avoid or reduce the possibility that the receiving / transmitting device cannot effectively sleep and thus the power is consumed excessively fast. Moreover, it can avoid or reduce the possibility that the operating duration of the receiving / transmitting device is reduced. It should be noted that the fact that the second round is the measurement round after the first round can be understood as that the second round is executed after the first round ends.

[0474] After the first round ends, the execution of the second round includes the following two cases.

[0475] Example 1: The second round and the first round are two adjacent ranging rounds. Specifically, the second round can be executed immediately after the first round ends. The end point of the first round is the start point of the second round, or the duration between the end point of the first round and the start point of the second round is less than a preset threshold value, and it can be understood that another ranging round is not included in the duration.

[0476] Example 2: The second round and the first round are not adjacent ranging rounds. Specifically, the second round is not executed immediately after the first round ends. In other words, there may be a specific time interval between the second round and the first round. For example, there is another ranging round between the second round and the first round. It can be understood that the duration between the end point of the first round and the start point of the second round is greater than a preset threshold value.

[0477] The value of the preset threshold is not limited in the embodiments of the present application. For example, in Example 2, there may be an interval of the duration of several rounds between the end point of the first round and the start point of the second round. The intervals of several rounds may be used in other ranging processes or may be idle.

[0478] For example, in Scenario 2, the interval duration between the end of the first round and the start of the second round being greater than a preset threshold value implies that the second round and the first round are not the same ranging block. For example, the first round is the ranging round in the current ranging block, and the second round is the ranging round in the next ranging block (e.g., a ranging block adjacent to the current ranging block). In this case, there is an interval of the duration of several rounds between the second round and the first round. The intervals of several rounds may be used in other ranging processes or may be idle. In another example, the first round is the ranging round in the current ranging block, and the second round may be the ranging round in a subsequent ranging block (e.g., a ranging block that is at least one other ranging block different from the current ranging block).

[0479] The aforementioned ranging block can be understood as having a time duration including one or more ranging rounds.

[0480] In another possible implementation, the transmitting device can send the first information and the third indication information to the control device at a first time point in the measurement phase of the first round. In this implementation, the control device can send the fourth indication information to the transmitting device and the receiving device before the measurement phase of the second round; or the control device can send the fourth indication information to the transmitting device and the receiving device at a second time point in the measurement phase of the first round.

[0481] The third UWB signal includes the UWB signal transmitted in the measurement phase of the second round and / or the UWB signal transmitted after the second time point in the measurement phase of the first round, and the second time point is after the first time point.

[0482] In this implementation, after receiving the fourth indication information, the transmitting device and the receiving device may transmit a third UWB signal based on the changed number of fragment signals in the second round of measurement phase, where the second round is a measurement round after the first round; alternatively, after receiving the fourth indication information, the transmitting device and the receiving device may transmit a third UWB signal based on the changed number of fragment signals after the second time point in the measurement phase of the first round. The inappropriate number of fragment signals can be adjusted within a time to an appropriate number of fragment signals based on the actual measurement effect of the current ranging round. Thereby, much time waste in the remaining time of the measurement phase of the current ranging round and many subsequent continuous ranging processes is avoided, and the system efficiency is improved. In addition, this implementation can avoid or reduce the possibility that the on-period of the receiver of the receiving / transmitting device is inappropriately configured, and further can avoid or reduce the possibility that the receiving / transmitting device cannot effectively sleep and thus power is consumed excessively fast, and further can avoid or reduce the possibility that the operating duration of the receiving / transmitting device is reduced. In the procedure shown in FIG. 8, the receiving device may be a measurement initiator device or a measurement responder device; alternatively, the initiator device and the control device are the same device, and the responder device and the control device are the same device. Hereinafter, the procedure of the signaling transmission method provided in the present application when the receiving device plays different roles in the ranging process will be described with reference to specific examples.

[0483] Example 4: The transmitting device is a ranging initiator device, the receiving device is a ranging responder device, and a control device is further included. The control device can be understood as a device for determining relevant parameters in the ranging procedure.

[0484] FIGS. 9(a) and 9(b) are schematic flowcharts corresponding to Example 4 and include the following steps.

[0485] Step 1: The initiator device transmits a polling signal to the responder device.

[0486] Step 2: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0487] Step 3: Transmit a UWB ranging signal between the initiator device and the responder device to perform ranging.

[0488] For distinction, the UWB ranging signal transmitted from the initiator device to the responder device in the ranging phase is shown as the fourth UWB signal #1, and the UWB ranging signal transmitted from the responder device to the initiator device is shown as the fourth UWB signal #2. In the case of Example 4, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #2.

[0489] The initiator device determines the third indication information based on the received fragment signal of the fourth UWB signal #2.

[0490] Step 4: The initiator device transmits the second information and the third indication information to the control device.

[0491] Step 4 includes two possibilities.

[0492] Possibility 1: As shown in FIG. 9(a), the initiator device transmits the second information and the third indication information in the current ranging phase.

[0493] Possibility 2: As shown in FIG. 9(b), the initiator device transmits the second information and the third indication information in the ranging report phase.

[0494] Step 5: The control device transmits the first information to the initiator device.

[0495] Step 6: The control device sends the fourth indication information to the initiator device and the responder device.

[0496] Specifically, after receiving the third indication information, the control device sends the fourth indication information to the initiator device and the responder device. The following several possibilities are included.

[0497] If the initiator 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 initiator device and the responder device in the current ranging phase; or before the ranging phase of the next ranging round starts (for example, in the ranging result reporting phase of the current ranging round or the control phase of the next ranging round), it may start sending the fourth indication information to the initiator device and the responder device. In FIG. 9(a), an example where the fourth indication information is sent to the initiator device and the responder device in the ranging result reporting phase of the current ranging round is used for illustration. The next ranging round may be a ranging round adjacent to the current ranging round, or may be a ranging round that is at least one other ranging round different from the current ranging round.

[0498] If the initiator device sends the second information and the third indication information in the ranging report phase of the current ranging round, the control device may send the fourth indication information to the initiator device and the responder device in the ranging report phase of the current ranging round; or before the ranging phase of the next ranging round starts (for example, in the control phase of the next ranging round), it may start sending the fourth indication information to the initiator device and the responder device. In FIG. 9(b), an example where the fourth indication information is sent to the initiator device and the responder device in the ranging result reporting phase of the current ranging round is used for illustration.

[0499] After stages 1 to 6, the initiator device and the responder device may transmit a UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal to perform subsequent procedures of UWB ranging.

[0500] For example, the fourth indication information indicates that the number of fragment signals of the UWB ranging signal is 8. In one possibility, after receiving the fourth indication information, the initiator device and the responder device directly use the changed number of fragment signals within a period after the number of fragment signals in the ranging phase of the current ranging round is changed to perform ranging. In another possibility, after receiving the fourth indication information, the initiator device and the responder device use the changed number of fragment signals in the next UWB ranging round to perform UWB ranging.

[0501] Example 5: The transmitting device is a ranging responder device, the receiving device is a ranging initiator device, and a control device is further included.

[0502] FIG. 10(a) and FIG. 10(b) are schematic flowcharts corresponding to Example 4 and include the following steps.

[0503] Step 1: The initiator device transmits a polling signal to the responder device.

[0504] Step 2: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0505] Step 3: Transmit a UWB ranging signal between the initiator device and the responder device to perform ranging.

[0506] For the sake of distinction, the UWB ranging signal transmitted from the initiator device to the responder device in the ranging phase is shown as the fourth UWB signal #1, and the UWB ranging signal transmitted from the responder device to the initiator device is shown as the fourth UWB signal #2. In the case of Example 5, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #1.

[0507] The responder device determines the third indication information based on the received fragment signal of the fourth UWB signal #1.

[0508] Step 4: The responder device transmits the second information and the third indication information to the control device.

[0509] Step 4 includes two possibilities.

[0510] Possibility 1: As shown in FIG. 10(a), the responder device transmits the second information and the third indication information in the current ranging phase.

[0511] Possibility 2: As shown in FIG. 10(b), the responder device transmits the second information and the third indication information in the ranging report phase.

[0512] Step 5: The control device transmits the first information to the responder device.

[0513] Step 6: The control device transmits the fourth indication information to the initiator device and the responder device.

[0514] Specifically, after receiving the third indication information, the control device transmits the fourth indication information to the initiator device and the responder device. The following several possibilities are included.

[0515] When the initiator device transmits the second information and the third indication information in the current ranging phase, the control device may transmit the fourth indication information to the initiator device and the responder device in the current ranging phase; or, before the ranging phase of the next ranging round starts (for example, in the ranging result reporting phase of the current ranging round or the control phase of the next ranging round), it may start transmitting the fourth indication information to the initiator device and the responder device. In FIG. 10(a), an example in which the fourth indication information is transmitted to the initiator device and the responder device in the ranging result reporting phase of the current ranging round is used for illustration.

[0516] When the initiator device transmits the second information and the third indication information in the ranging report phase of the current ranging round, the control device may transmit the fourth indication information to the initiator device and the responder device in the ranging report phase of the current ranging round; or, before the ranging phase of the next ranging round starts (for example, in the control phase of the next ranging round), it may start transmitting the fourth indication information to the initiator device and the responder device. In FIG. 10(b), an example in which the fourth indication information is transmitted to the initiator device and the responder device in the ranging result reporting phase of the current ranging round is used for illustration.

[0517] After steps 1 to 6, the initiator device and the responder device may transmit the UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal to perform subsequent procedures of UWB ranging.

[0518] Example 6: In the ranging procedure, the transmitting device is the ranging initiator device, the receiving device is the ranging responder device, and the initiator device is the control device.

[0519] Figs. 11(a) and 11(b) are schematic flowcharts corresponding to Example 6 and include the following steps.

[0520] Step 1: The initiator device sends a polling signal to the responder device.

[0521] Step 2: The responder device sends a response signal to the initiator device in response to the polling signal.

[0522] Step 3: Transmit a UWB ranging signal between the initiator device and the responder device to perform ranging.

[0523] For distinction, the UWB ranging signal transmitted from the initiator device to the responder device in the ranging phase is shown as the fourth UWB signal #1, and the UWB ranging signal transmitted from the responder device to the initiator device is shown as the fourth UWB signal #2. In the case of Example 4, the fourth UWB signal in the embodiment shown in Fig. 8 is the fourth UWB signal #2.

[0524] The initiator device determines the third indication information based on the received fragment signal of the fourth UWB signal #2.

[0525] Step 4: The initiator device sends the third indication information to the responder device.

[0526] Step 4 includes two possibilities.

[0527] Possibility 1: As shown in Fig. 11(a), the initiator device sends the third indication information in the current ranging phase.

[0528] Possibility 2: As shown in Fig. 11(b), the initiator device sends the third indication information in the ranging report phase.

[0529] After stages 1 through 4, the initiator device and the responder device may transmit a UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal to perform subsequent procedures of UWB ranging.

[0530] For example, when the initiator device transmits third indication information in the current ranging phase, after receiving the third indication information, the responder device directly uses the changed number of fragment signals within the period after the number of fragment signals in the ranging phase of the current ranging round is changed to perform ranging. In another possibility, the initiator device and the responder device use the changed number of fragment signals in the next UWB ranging round to perform UWB ranging.

[0531] In another example, when the initiator device transmits third indication information in the ranging report phase, the initiator device and the responder device use the changed number of fragment signals in the next UWB ranging round to perform UWB ranging.

[0532] Example 7: In the ranging procedure, the transmitting device is the ranging initiator device, the receiving device is the ranging responder device, and the responder device is the control device.

[0533] Figures 12(a) and 12(g) are schematic flowcharts corresponding to Example 7 and include the following steps.

[0534] Step 1: The initiator device transmits a polling signal to the responder device.

[0535] Step 2: The responder device transmits a response signal to the initiator device in response to the polling signal.

[0536] Step 3: Transmit a UWB ranging signal between the initiator device and the responder device to perform ranging.

[0537] For the sake of distinction, the UWB ranging signal transmitted from the initiator device to the responder device in the ranging phase is shown as the fourth UWB signal #1, and the UWB ranging signal transmitted from the responder device to the initiator device is shown as the fourth UWB signal #2. In the case of Example 4, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #2.

[0538] The initiator device determines the third indication information based on the received fragment signals of the fourth UWB signal #2.

[0539] Step 4: The initiator device transmits the second information and the third indication information to the responder device.

[0540] Step 4 includes two possibilities.

[0541] Possibility 1: As shown in FIG. 12(a), the initiator device transmits the second information and the third indication information in the current ranging phase.

[0542] Possibility 2: As shown in FIG. 12(b), the initiator device transmits the second information and the third indication information in the ranging report phase.

[0543] Step 5: The responder device transmits the fourth indication information to the initiator device.

[0544] Specifically, after receiving the third indication information, the responder device transmits the fourth indication information to the initiator device. The following several possibilities are included.

[0545] When the initiator device transmits the second information and the third indication information in the current ranging phase, the responder device may transmit the fourth indication information to the initiator device in the current ranging phase; or, before the ranging phase of the next ranging round starts (for example, the ranging result reporting phase of the current ranging round or the control phase of the next ranging round), it may start transmitting the fourth indication information to the initiator device. In FIG. 12(a), an example where the fourth indication information is transmitted to the initiator device and the responder device in the ranging result reporting phase of the current ranging round is used for illustration.

[0546] When the initiator device transmits the second information and the third indication information in the ranging report phase of the current ranging round, the responder device may transmit the fourth indication information to the initiator device in the ranging report phase of the current ranging round; or, before the ranging phase of the next ranging round starts (for example, the control phase of the next ranging round), it may start transmitting the fourth indication information to the initiator device. In FIG. 12(b), an example where the fourth indication information is transmitted to the initiator device and the responder device in the ranging result reporting phase of the current ranging round is used for illustration.

[0547] After steps 1 to 5, the initiator device and the responder device may transmit the UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal to execute the subsequent procedures of UWB ranging.

[0548] Alternatively, in the ranging process, when the receiving device is the ranging responder device and the responder device is the control device, the control device may directly indicate the number of fragment signals of the UWB ranging signal, and the number of fragment signals of the UWB ranging signal need not be determined based on the third indication information transmitted by the initiator device. For example, after steps 1 and 3 are executed, the following steps are executed.

[0549] Step 4a: The responder device transmits fourth indication information to the initiator device.

[0550] Step 4a includes two possibilities.

[0551] Possibility 1: As shown in FIG. 12(c), the responder device transmits fourth indication information in the current ranging phase.

[0552] Possibility 2: As shown in FIG. 12(d), the responder device transmits fourth indication information in the ranging reporting phase.

[0553] After steps 1 to 4a, the initiator device and the responder device may transmit the UWB ranging signal based on the determined number of fragment signals of the UWB ranging signal to execute subsequent procedures of UWB ranging.

[0554] In the procedures shown in FIGS. 6 and 8, how to determine the number of fragment signals of the UWB signal transmitted in the measurement phase based on the UWB test signal and how to indicate the number of fragment signals of the UWB signal are described in detail.

[0555] In a possible implementation, determining the number of fragment signals of the UWB signal transmitted by the transmitting device in the measurement phase is a procedure that need not be triggered.

[0556] In another possible implementation, determining the number of fragment signals of the UWB signal transmitted by the transmitting device in the measurement phase is a procedure triggered based on a trigger request sent by the receiving device. For example, the transmitting device may be a control device.

[0557] For example, the receiving device is a ranging responder device, and the transmitting device is a ranging initiator device. In the first round of measurement reporting phase, if the responder device needs to change the number of fragment signals of the UWB signal transmitted in the measurement phase of a subsequent round (e.g., the second round), the following information, namely, a change request message, the updated number of fragment signals (e.g., the FFNE IE message described above), or information related to the change in the number of fragment signals of the UWB signal, etc. At least one of them is carried in a reporting message (e.g., a narrowband signal) related to the ranging result and returned to the transmitting device. The change request message instructs to change the number of fragment signals of the UWB signal. For example, the change request message may be the RCR IE described above.

[0558] That is, information related to the change in the number of fragment signals of the UWB signal and the reporting message returned by the responder device to the initiator device related to the ranging result can be combined for reporting in one message.

[0559] In another example, in the measurement phase of the first round, if the receiving device needs to change the number of fragment signals of the UWB signal transmitted in the measurement phase of a subsequent round (e.g., the second round), the receiving device may send a change request message (which may be a narrowband signal, for example) to the transmitting device. The change request message is used to request to change the number of fragment signals of the UWB signal transmitted in the measurement phase of a subsequent round (e.g., the second round). The change request message contains the following information, namely, A change request message, the updated number of fragment signals (e.g., the above-mentioned FFNE IE message), or information related to a change in the number of UWB, etc. includes at least one of them. The change request message instructs to change the number of fragment signals of the UWB signal. For example, the change request message may be the above-mentioned RCR IE.

[0560] That is, information related to the number of fragment signals of the UWB signal transmitted in the process of the measurement phase, that is, information related to the ranging result and the report message do not need to be combined for transmission. For example, the order of the transmission slots of the change request message and the UWB signal transmitted from the receiving device to the transmitting device can be exchanged to be applicable to different scenarios.

[0561] For example, the change request message is transmitted after the receiving device transmits the UWB signal to the transmitting device, which is applicable to scenarios where the receiving device needs more time to process the fragment signals of the UWB signal from the initiator. In another example, the change request message is transmitted before the receiving device transmits the UWB signal to the transmitting device, which is applicable to scenarios where the receiving device needs to respond quickly to the transmitting device.

[0562] In addition, it should be noted that the above-mentioned procedure for triggering the update of the number of fragment signals of the UWB signal by the receiving device is applicable to another scenario, that is, the trigger procedure may be independent. For example, the method of determining the number of fragment signals of the UWB signal before the change request is not limited. When the receiving device needs to change the number of fragment signals of the UWB signal, the trigger procedure can be used to trigger the update of the number of fragment signals of the UWB signal.

[0563] For example, the method of determining the number of fragment signals of the UWB signal before the change request may be the aforementioned method of determining the number of fragment signals of the UWB signal based on the UWB test signal in the ranging control phase, or may be another existing or future method of determining the number of fragment signals of the UWB signal.

[0564] For ease of understanding, with reference to FIGS. 12(e) to 12(g), the procedure for the receiving device to trigger the update of the number of fragment signals of the UWB signal will be described in detail.

[0565] Possibility 1: The receiving device transmits a change request message to the transmitting device in the measurement result reporting phase of the current measurement round to trigger the update of the number of fragment signals of the UWB signal in the next measurement round.

[0566] Possibility 1: As shown in FIG. 12(e), the change request message may be carried in a report message related to the ranging result.

[0567] Possibility 2: As shown in FIGS. 12(f) and 12(g), the receiving device transmits a change request message to the transmitting device in the measurement phase of the current measurement round to trigger the update of the number of fragment signals of the UWB signal in the next measurement round.

[0568] It can be seen from the examples shown in FIGS. 12(f) and 12(g) that the order of the transmission slots of the change request message and the UWB signal transmitted by the receiving device to the transmitting device may be exchanged.

[0569] In the procedure for triggering the update of the number of fragment signals of the UWB signal shown in FIGS. 12(e) to 12(g), the receiving device is the responder device, and the transmitting device is the initiator device; or the receiving device is the initiator device, and the transmitting device is the responder device. Additionally, in the example shown in FIGS. 12(e) to 12(g), the transmitting device is the control device. Alternatively, the control device may be a third party or the receiving device, and the procedure is the same as that in FIGS. 12(e) to 12(g), and will not be described again in detail.

[0570] It should be noted that the above-described procedure for triggering the update of the number of fragment signals of the UWB signal can be used in combination with the above-described procedure for determining the number of fragment signals of the UWB signal.

[0571] For example, in the example shown in FIG. 6 or FIG. 8, in the measurement result reporting phase and / or the measurement phase of the previous measurement round before the number of fragment signals of the UWB signal is determined in the current measurement round, the transmitting device receives a change request message from the receiving device. For example, before step S611, the transmitting device receives a change request message from the receiving device; or After the number of fragment signals of the UWB signal is determined in the current measurement round, in the measurement result reporting phase and / or the measurement phase of the current measurement round, the receiving device transmits a change request message to the transmitting device to update the number of fragment signals of the UWB signal to be transmitted in the next measurement round. For example, after step S632, the receiving device transmits a change request message to the transmitting device.

[0572] It should be understood that the sequence numbers of the above-described processes do not mean the execution order. The execution order of the processes should be determined based on the functions and the internal logic of the processes, and should not be construed as any limitation on the implementation process of the embodiments of the present application.
