Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202210637088.2, entitled “Signaling Transmission Method and Apparatus,” filed with the China National Intellectual Property Administration on 7 June 2022, and Chinese Patent Application No. 202210783842.3, entitled “Signaling Transmission Method and Apparatus,” filed with the China National Intellectual Property Administration on 5 July 2022, both of which are incorporated herein by reference in their entirety.

[0002] Embodiments of the present invention relate to the field of communications, and more specifically to signaling transmission methods and apparatus. [Background technology]

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

[0004] In ranging or detection scenarios, the accuracy of the measurement or detection results is highly dependent on the signal bandwidth. A larger signal bandwidth results in higher accuracy of the results obtained through detection or ranging. Therefore, a reference signal for ranging or detection can be considered to be received and transmitted using a UWB system, and another reference signal and / or data can be considered to be transmitted based on a narrowband protocol. This processing method can be understood as narrowband protocol-assisted UWB ranging or detection.

[0005] In current narrowband protocol-assisted UWB ranging methods, during the ranging control phase, the responder roughly estimates the number of UWB ranging signal fragments that need to be used in the ranging phase of the current UWB ranging round, based on the power intensity of the narrowband signal received from the initiator. This can confuse the initiator in configuring parameters during the ranging phase and reduce system efficiency. Therefore, improving the performance of narrowband protocol-assisted UWB ranging or detection methods is an urgent issue that needs to be addressed. [Overview of the project]

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

[0007] According to a first embodiment, a signaling transmission method is provided. The method may be performed by a receiving device or by a component of the receiving device (e.g., a chip or circuit). This is not limited to the method. For the sake of clarity, an example in which the method is performed by a receiving device is used below for illustrative purposes. It should be understood that the receiving device may be a measurement responder device or a measurement initiator device.

[0008] The signaling transmission method comprises the steps of: a receiving device receiving a first ultra-wideband UWB signal from a transmitting device; and the receiving device transmitting first indication information to the transmitting device, wherein 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, the receiving device determines the number of fragments of a second UWB signal to be transmitted based on the received first UWB signal, instead of determining the number of fragments of the UWB signal based on the narrowband signal. Compared to a solution that estimates the number of fragments of the UWB signal based on the narrowband signal, this technical solution has a more accurate number, reduces the possibility of misconfiguring the number of fragments of the UWB signal, and avoids or reduces the possibility of reduced system efficiency.

[0010] In addition, if the number of UWB signal fragments is incorrectly configured, the on-time of the receiver in the receiving / transmitting device may be improperly configured. However, this technical solution can avoid or reduce the possibility of the on-time of the receiver in the receiving / transmitting device being improperly configured, and further, it can avoid or reduce the possibility of excessively fast power consumption because the receiving / transmitting device cannot effectively sleep, and further, it can avoid or reduce the possibility of reduced operating time of the receiving / transmitting device.

[0015] In relation to the first aspect, in some implementations of the first aspect, the method further comprises the steps of: a receiving device receiving first configuration information from a transmitting device, wherein the first configuration information represents the configuration of a first UWB signal; and / or the receiving device receiving second configuration information from a transmitting device, wherein the second configuration information represents the configuration of a second UWB signal.

[0016] Based on the technical solution, the transmitting device may implement the relevant configuration of the UWB signal based on the configuration information, and as a result, the receiving device can successfully receive the UWB signal.

[0017] In relation to the first embodiment, in some implementations of the first embodiment, the method further comprises the step of a receiving device receiving second indication information from a transmitting device, where the second indication information indicates a second number of fragment signals of a second UWB signal, and the second indication information is determined based on the first indication information.

[0018] Based on the technical solution, the transmitting and receiving devices can negotiate an appropriate number of UWB signal fragments. This improves the accuracy of the solution.

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

[0021] In relation to the first embodiment, in some implementations of the first embodiment, a fifth UWB signal is used to determine the fifth number of fragment signals of the second UWB signal, and the fourth number of fragment signals of the second UWB signal is determined based on the first number of fragment signals of the second UWB signal and the fifth number of fragment signals of the second UWB signal.

[0148] The technical solution of this application will be described below with reference to the attached drawings.

[0149] Embodiments of this application are applicable to wireless personal area networks (WPANs) based on ultra-wideband (UWB) technology. Currently, the standard for WPANs is the Institute of Electrical and Electronics Engineers (IEEE) 802.15 series. WPANs 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 a WPAN is typically within 10 meters. Technologies that support wireless personal area networks include Bluetooth®, ZigBee®, ultra-wideband, infrared data association (IrDA) connectivity technology, and home radio frequency (HomeRF) technology. Those skilled in the art will readily understand that the various embodiments of this application can be extended to other networks using various standards or protocols, such as Wireless Local Area Networks (WLANs), High Performance Radio LANs (HIPERLANs) (a wireless standard similar to the IEEE 802.11 standard mainly used in Europe), and Wide Area Networks (WANs), or to other networks that are currently known or may be developed in the future. From a network configuration standpoint, WPAN is located at the lowest layer of the overall network architecture and is for wireless connections between devices within a small range, i.e., point-to-point short-range connections, and can be considered a short-range 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 a variety of high-speed multimedia applications, including high-quality audio-visual distribution, multi-megabyte music and image document transmission, etc.LR-WPAN may be used for general services in daily life.

[0150] In a Personal Area Network (PAN), devices can be classified into full-function devices (FFDs) and reduced-function devices (RFDs) based on their communication capabilities. FFD devices can communicate with each other, and FFD and RFD devices can communicate with each other. RFD devices cannot communicate directly with each other, but can communicate only with FFD devices or transfer data externally through one FFD device. An FFD device associated with an RFD is called an RFD coordinator. A coordinator can control and associate multiple FFDs. A coordinator is also called a control node. Multiple coordinators can exist in each ad-hoc network. RFD devices are primarily intended for simple control applications such as light switches and passive infrared sensors, transmitting small amounts of data and occupying few transmission and communication resources. Therefore, RFD devices are inexpensive. A coordinator may also be called a Personal Area Network (PAN) coordinator. A PAN coordinator may be understood as one type of coordinator, and is also referred to as a PAN central control node, etc. An FFD can function as a PAN coordinator or coordinator, while an RFD cannot function as a PAN coordinator or coordinator. A PAN coordinator is the main control node for the entire network, and each ad-hoc network may have only one PAN coordinator, which has member identification information management, link information management, and packet forwarding functions. Optionally, the devices in 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 the embodiments of this application, the device may be a communication server, router, switch, bridge, computer, mobile phone, home smart device, or in-vehicle communication device, etc.

[0152] In embodiments of the present application, the device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and 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 processes, such as the Linux® operating system, Unix® operating system, Android® operating system, iOS® operating system, or Windows® operating system. The application layer includes applications such as a browser, contacts, word processing software, and instant messaging software. In addition, the particular structure of the implementer of the method provided in embodiments of the present application is not particularly limited in embodiments of the present application, provided that a program that records the code of the method provided in embodiments of the present application can be operated to perform communication according to the method provided in embodiments of the present application. For example, the method provided in embodiments of the present application may be performed by an FFD or RFD, or by a functional module within an FFD or RFD that can call and execute a program.

[0153] In addition, aspects or features of the present application may be implemented as methods, apparatus or products using standard programming and / or engineering techniques. As used herein, the term “product” includes computer programs that can be accessed from any computer-readable component, carrier or medium. For example, computer-readable medium may include, but is not limited to, magnetic storage components (e.g., hard disks, floppy disks or magnetic tapes), optical discs (e.g., compact discs (CDs), digital versatile discs (DVDs)), smart cards and flash storage components (e.g., erasable programmable read-only memory (EPROMs)), cards, sticks or key drives). In addition, the various storage media described herein may represent one or more devices and / or other machine-readable media configured to store information. The term “machine-readable medium” may include, but is not limited to, wireless channels and various other media that can store, contain and / or carry instructions and / or data.

[0154] Alternatively, embodiments of the present invention are further applicable to wireless local area network systems such as Internet of Things (IoT) networks or Vehicle to Everything (V2X). Naturally, embodiments of the present invention are further applicable to other possible communication systems, such as long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunications systems (UMTS), worldwide interoperability for microwave access (WiMAX®) communication systems, 5th generation (5G) communication systems, and future 6th generation (6G) communication systems.

[0155] The aforementioned communication systems to which this application is applicable are merely illustrative examples, and the communication systems to which this application is applicable are not limited to these. This has been explained uniformly here and will not be explained in detail again below.

[0156] Figure 1 illustrates two application scenarios according to the present invention. In system 101 shown in Figure 1(A), multiple FFD devices and multiple RFD devices form a communication system having a star topology, with one FFD acting as 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 between multiple devices. In system 102 shown in Figure 1(B), multiple FFD devices and one RFD device form a communication system having a peer-to-peer topology or a mesh topology, with one FFD acting as a PAN controller. In a communication system having a peer-to-peer topology, a many-to-many data transmission architecture can be established between multiple different devices.

[0157] Figures 1(A) and 1(B) are simplified diagrams for ease of understanding and should be understood as not constituting limitations on the application scenarios of this invention. For example, system 101 and / or system 102 may further include another FFD and / or another RFD. In another example, the PAN coordinator in system 101 may be a coordinator, and / or the PAN coordinator in system 102 may be a coordinator.

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

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

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

[0161] UWB technology performs data transmission through the reception and transmission of nanosecond or sub-nanosecond and extremely narrow impulses, rather than carriers as in conventional communication systems, thus requiring high time synchronization for 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 over ultra-wideband channels, and most UWB communication devices are battery-powered. Next-generation standards are expected to further reduce the power consumption of UWB systems. Therefore, all signals except for ranging and sensing reference signals will be received and transmitted using narrowband signal-assisted methods in narrowband systems. This will reduce the overall power consumption overhead.

[0162] 2. Power of UWB signals: Due to the large bandwidth of operating ultra-wideband systems, the FCC imposes strict limits on the power spectral density of UWB signals to reduce interference with other narrowband devices. According to the Code of Federal Regulations (CFR), the following two rules exist:

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

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

[0165] Rule 1 limits the total energy transmitted by UWB within one millisecond (e.g., 37 nJ for a 500 MHz bandwidth). This energy is transmitted in a shorter time. This increases the instantaneous power of the transmitted signal, expands signal coverage, and improves the signal-to-noise ratio of the signal received at the receiver. Based on this, in some scenarios where increased transmission power is necessary, the transmitter divides the UWB signal to be transmitted into multiple fragment signals (each fragment signal having a duration of less than one millisecond), and then transmits only one fragment signal per millisecond.

[0166] To facilitate understanding, the UWB signal will be briefly explained with reference to Figure 2. Figure 2 is a diagram of the UWB signal according to one embodiment of the present invention.

[0167] Figure 2 shows 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 Figure 2). The duration of each fragment signal is less than 1 millisecond, and one of the fragment signals is transmitted at each millisecond interval. The signal type of the fragment signals is also a UWB signal.

[0168] In addition, the term "fragment signal" in this application may also be referred to as a "block signal," "short signal," "partial signal," "fragment," or "block." The name of the fragment signal is not limited and should be able to identify that a UWB signal is divided into multiple UWB signals. The duration of each of the multiple UWB signals obtained after division is less than 1 millisecond, and one of the UWB signals obtained after division is transmitted in each millisecond. The multiple fragment signals obtained by dividing the UWB signal may be the same, at any discretion. For example, the multiple fragment signals obtained by dividing the UWB signal are a preamble with 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.

[0169] From the above, it can be seen that the UWB signal to be transmitted is divided into multiple fragment signals for fragment transmission. This allows the instantaneous power of the UWB signal to be increased, but it is not possible to increase the instantaneous power indefinitely. Rule 2 actually limits the power increase factor of UWB-based fragment transmission.

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

[0171] 3. Impulse Radio Ultra-Wideband (IR-UWB) Systems: Due to the large bandwidth of ultra-wideband systems, devices in ultra-wideband systems need to have ultra-high-speed data reception and transmission capabilities. However, the spectral efficiency of IR-UWB systems based on impulse transmission is low, and the power consumption overhead required by IR-UWB solutions is much higher than that of other narrowband short-range protocols (e.g., Bluetooth or ZigBee) when transmitting the same information.

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

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

[0174] For ease of understanding, a ranging / positioning system to which the aforementioned ranging technique is applied will be briefly described with reference to Figure 3. Figure 3 is a diagram of the architecture of a ranging / positioning system according to one embodiment of the present invention. As shown in Figure 3, the ranging / positioning system includes a plurality of devices (device 1 and device 2 shown in Figure 3), which may be the apparatus in the embodiments of the present invention. Each device includes at least a UWB module, and a device may further include a narrowband communication module. Ranging, positioning, and communication may be performed between the UWB modules of device 1 and device 2. If these devices include a narrowband communication module, data transmission may be performed between the narrowband communication modules of device 1 and device 2 via a wireless link.

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

[0176] The devices in this application may be wireless communication chips, wireless sensors, or wireless communication terminals, such as user terminals, user devices, access devices, subscriber stations, subscriber units, mobile stations, user agents, and user equipment that support Wi-Fi communication functionality. User terminals may include various handheld devices, in-vehicle devices, wearable devices, Internet of Things (IoT) devices, or computing devices with wireless communication capabilities, 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 devices configured to perform network communication over a wireless medium. In addition, the devices may support the 802.15.4ab standard or the next-generation standard of 802.15.4ab. This device further supports multiple standards, including 802.15.4a, 802.15.4-2011, 802.15.4-2015, and 802.15.4z. It may also support multiple wireless local area network (WLAN) standards in the 802.11 family, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, and next-generation versions of 802.11be.

[0177] 5. Figure of Merit (FoM) Field: In previous generations of the 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 distance measurement signal is used to determine the distance measurement result. The fact that the FoM field indicates the accuracy of estimating the arrival time of the distance measurement signal can also be understood as the FoM field being used to evaluate the reliability level of the distance measurement result. In this application, the FoM field may also be referred to as the distance measurement reliability level field and indicates the distance measurement reliability level.

[0179] Specifically, the ranging reliability level fields are shown in Table 1 below. [Table 1: Rangefinder Reliability Level Field List] [Table 1]

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

[0181] A higher confidence level in Table 2 indicates that the current distance measurement result is more reliable, while "No FoM" in Table 2 indicates that the current distance measurement 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. A ranging round is divided into three phases: the ranging control phase, the ranging phase, and the measurement report phase. Figure 4 shows the phases of a UWB ranging round. As can be seen from Figure 4, in IEEE 802.15.4z, the ranging control phase includes one ranging slot, whereas in the currently discussed IEEE 802.15.4ab standard, 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 Figure 4 may be understood as the measurement control phase, the ranging phase may be understood as the measurement phase, and the ranging result reporting phase may be understood as the measurement result reporting phase. For example, the signaling transmission method provided in this application is applied to a narrowband protocol-assisted UWB detection procedure. The measurement control phase may be understood as the detection control phase, the measurement phase may be understood as the detection phase, and the measurement result reporting phase may be understood as the detection result reporting phase.

[0184] Furthermore, it should be noted that the names of the different phases of a single measurement round, as described above, are merely examples and do not constitute any limitation on the scope of protection 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 taking the measurement; and in yet another example, the measurement results reporting phase may be understood as the phase for reporting the measurement results, and may 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 Figure 5. Figure 5 is a diagram of the UWB ranging method. Figure 5 includes an initiator and a responder. The initiator may be a device with communication capabilities in the WPAN (e.g., an FFD or RFD shown in Figure 1), not an exclusive example. Similarly, the responder may be a device with communication capabilities in the WPAN (e.g., an FFD or RFD shown in Figure 1).

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

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

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

[0189] Specifically, after the initiator receives the response frame, it performs a round-trip time measurement with the responder using a fragment transmission method over a UWB channel. After the measurement is complete, the responder sends the measurement results (report) to the initiator using a narrowband system.

[0190] The above describes a scenario to which the embodiments of this application are applied with reference to Figure 1, further provides a brief explanation of the basic concepts in this application, and briefly describes the UWB distance measurement method with reference to Figure 5. This method has the following drawbacks.

[0191] NB channels and UWB channels have different bandwidths and signal waveforms. As a result, the conditions of NB channels and UWB channels differ significantly, leading to different channel attenuations. Specifically, UWB signals have nanosecond-level ultrashort impulse durations, high temporal resolution, and very wide transmission bandwidths. In indoor multipath environments, UWB receivers can coherently increase the impulse energy received from each multipath component to provide the gain of reception through a single path. According to existing studies, in indoor multipath cases, the level intensity value of a UWB received signal can vary from -5dB to +5dB relative to the average level intensity value. Therefore, the possibility of deep fading of UWB signals is low, which allows them to effectively withstand multipath fading.

[0192] In contrast, NB signals are more susceptible to multipath interference. Existing studies indicate that in indoor multipath scenarios, the level intensity of the received NB signal can vary by -20dB to -30dB relative to the average value. Therefore, the NB signal is more prone to deep fading, making it less tolerant of multipath fading.

[0193] In conclusion, in the UWB ranging method shown in Figure 5, serious distortion occurs if the responder roughly estimates the number of UWB ranging signal fragments required in the UWB ranging phase based on the NB signal strength. This leads to the initiator misconfiguring parameters in the ranging phase, reducing system efficiency. For example, the initiator may misconfigure a large number of UWB ranging signal fragments in the ranging phase. This results in excessively long ranging times, affecting access and implementation of ranging tasks for other ranging users, prolonging system delays, and reducing system efficiency. In addition, an inaccurate configuration of the number of UWB signal fragments prevents the receiving / transmitting device from effectively sleeping, affecting the operating duration of the receiving / transmitting device, which may lead to an inappropriate configuration of the receiver's on-time, and furthermore, excessively fast power consumption. To solve the problems in the aforementioned UWB ranging method, the present invention provides a signaling transmission method. The number of UWB signal fragments transmitted during the measurement phase is determined based on the UWB signal transmitted during the control phase. This improves the accuracy of determining the number of UWB signal fragments. The signaling transmission method provided in this application will be described in detail below with reference to the attached drawings.

[0194] The specific structure of the implementer of the method provided in the embodiments of the present application is not particularly limited in the following embodiments, provided that a program that records the code of the method provided in the embodiments of the present application can be executed in order to perform communication according to the method provided in the embodiments of the present application. For example, the method provided in the embodiments of the present application may be executed by a transceiver device or a functional module within a transceiver device that can call and execute a program.

[0195] To facilitate understanding of the embodiments of this application, the following explanation is provided.

[0196] First, in this application, "to show" may include "to show directly" and "to show indirectly." When one piece of information is described as showing A, this information may show A directly or indirectly, but this does not indicate that the information is reliably carrying A.

[0197] The information indicated by this information is referred to as the indicated information. In a particular implementation process, the indicated information may be indicated in multiple ways, for example, in a way in which the indicated information, such as the indicated information or an index of the indicated information, can be directly indicated. Alternatively, the indicated information may be indicated indirectly by indicating other information, and a correspondence exists between the other information and the indicated information. Alternatively, only a part of the indicated information may be indicated, and the other parts of the indicated information may be known or pre-agreed. For example, to reduce indication overhead to some extent, certain information may, alternatively, be indicated in a pre-agreed (e.g., specified in a protocol) arrangement sequence of multiple pieces of information. In addition, to reduce the indication overhead caused by indicating the same information separately, the common parts of all information may be identified and indicated in a unified way.

[0198] Secondly, the various numbers shown in this application, such as the first and second (e.g., "#1" and "#2"), are merely for illustrative purposes and are used to distinguish between subjects, but are not intended to limit the scope of the embodiments of this application. For example, these numbers are used to distinguish between different channels, but not to describe a specific order or sequence. Subjects described in this way are interchangeable in appropriate circumstances, and it should be understood that solutions other than the embodiments of this application may be described as a result.

[0199] Thirdly, in this application, “pre-configured” may include “pre-defined,” for example, defined in a protocol. “Pre-defined” can be implemented in a manner that pre-stores corresponding codes, tables, or other related information that may be for indications within a device (for example, including network elements). Specific implementations are not limited in this application.

[0200] Fourth, “storage” in embodiments of the present application may mean storage in one or more storage devices. These storage devices may be separately located or integrated into an encoder or decoder, processor or communication device. Alternatively, some of the storage devices may be separately located, or some of the storage devices may be integrated into a decoder, processor or communication device. The type of storage may be any form of storage medium; this is not limited to the present application.

[0201] Fifth, the term “and / or” as used herein is merely a correspondence to describe the related subjects, and three such relationships may exist. For example, A and / or B may refer to three cases: A alone exists, both A and B exist, and B alone exists. In addition, the letter “ / ” as used herein usually indicates an “or” relationship between the related subjects.

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

[0203] Without loss of generality, the signaling transmission method provided in the embodiments of this application will be described in detail below, using the interaction between a transmitting device and a receiving device as an example. The transmitting device may also be abbreviated as the transmitting side, and the receiving device may also be abbreviated as the receiving side.

[0204] As an example, and not an limitation, the transmitting device may be a device with communication capabilities in WPAN, such as an FFD or RFD. Similarly, the receiving device may also be a device with communication capabilities in WPAN, such as an FFD or RFD.

[0205] Please understand that the specific types and names of the transmitting and receiving devices are not limited in this application, provided that the transmitting and receiving devices are communication devices capable of receiving and transmitting UWB and NB signals.

[0206] Figure 6 is a schematic flowchart of a signaling transmission method according to one embodiment of the present invention. This method includes the following steps.

[0207] S610: The transmitting device sends 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 during 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 during the control phase. The measurement includes measurement processes such as distance measurement or detection performed based on the UWB signal. For example, the first round may be any distance measurement round; or, in another example, the first round may be any detection round.

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

[0210] In this embodiment, the first UWB signal is used to determine first indication information, which 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] The fragment signals included in the second UWB signal are, at will, identical. For example, the fragment signals included in the second UWB signal are preambles with the same configuration. The identical configuration of the preambles includes, but is not limited to, the preamble length and the sequence used by the preamble.

[0212] For clarity, the first UWB signal may be referred to as the UWB test signal, and the second UWB signal may be referred to as the UWB measurement signal. The second UWB signal includes the UWB ranging signal and / or the UWB detection signal. The second UWB signal can be understood as the UWB signal used to implement the measurement, transmitted during the measurement phase of the first round (e.g., the ranging phase or the detection phase).

[0213] It should be noted that the specific function of the second UWB signal is not limited to the embodiments of this application. The second UWB signal may be a UWB signal for distance measurement, or a UWB signal for detection, or a UWB signal that implements 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: the second UWB signal is divided into multiple fragment signals (shown in Figure 2) during the transmission process. The time length of each fragment signal is less than 1 millisecond, and therefore only one fragment signal is transmitted within each millisecond, and the number of multiple fragment signals is indicated as the first number. For example, the fragment signals included in multiple fragment signals are the same. For example, the fragment signals included in multiple fragment signals are preambles with 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.

[0215] If, optionally, the number of second UWB signal fragments expected by the transmitting device differs from the number of second UWB signal fragments expected by the receiving device, the transmitting and receiving devices may negotiate to obtain an appropriate number of second UWB signal fragments for transmission. The negotiation process is described below with reference to specific stages, and further details are not described here.

[0216] In possible implementations, the first indication information implicitly indicates the number of fragment signals. For example, the first indication information is a fragment number index, which indicates the first number of fragment signals in the second UWB signal expected by the transmitting device. In another example, the first indication information is an FoM value corresponding to the first UWB signal, which is used to determine the first number of fragment signals in the second UWB signal expected by the transmitting device.

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

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

[0219] FNI stands for Fragment Number Index.

[0220] In another example, the transmitting and receiving devices acquire or locally store a third mapping relationship (for example, the transmitting and receiving devices negotiate to determine and store the third mapping relationship, or the third mapping relationship is predefined in the protocol), which 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 may determine the number of fragment signals based on the locally stored third mapping relationship.

[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, if the value of the first indication information is 1, this indicates that the number of fragment signals is 1; if the value of the first indication information is 2, this indicates that the number of fragment signals is 2; ...; if 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] The above is merely an example to illustrate possible forms of the first indication information and should not constitute any limitation on the scope of protection of this application. Other indication information that may indicate the number of fragment signals is included in the scope of protection of this application. For example, the first indication information indicates the confidence level corresponding to a first UWB signal, and the confidence level corresponding to the first UWB signal is used to determine the first number of fragment signals of a second UWB signal expected by the transmitting device. For ease of explanation, the following example uses a fragment number index for illustrative purposes as the first indication information.

[0225] From the above, it can be seen 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 it. Optionally, the procedure of the method shown in Figure 6 further includes the following steps.

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

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

[0228] Step 1: The receiving device determines the 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 judged or estimated that the reliability level corresponding to the first UWB signal is high and, optionally, that the corresponding FoM value is large; or, if the quality of the first UWB signal is poor, it is estimated that the reliability level corresponding to the first UWB signal is low and, optionally, that the corresponding FoM value is small.

[0230] In this embodiment, it should be understood that the method for determining the reliability level corresponding to the first UWB signal based on the quality of the first UWB signal is not limited. For details, see the description of the step for determining the reliability level corresponding to the model in current related technologies based on signal quality. Further details will not be described here.

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

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

[0233] For example, a mapping relationship (referred to as the first mapping relationship for clarity) exists between the reliability level and the number of fragment signals in the second UWB signal. The receiving device may determine the number of fragment signals in 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 Tables 4a and 4b below. [Table 4a: Example 1 of the mapping relationship between reliability level and number of fragmented signals] [Table 5] [Table 4b: Example 2 of the mapping relationship between reliability level and number of fragmented signals] [Table 6]

[0235] Tables 4a and 4b illustrate possible forms of the first mapping relationship by example and should be noted as not constituting any limitation on the scope of protection of this application. The first mapping relationship may alternatively be another form that may show a relationship between the reliability level and the number of fragment signals. For example, Tables 4a and 4b include two columns, reliability level and number of fragment signals, where the reliability level index and FNI are optional. The examples will not be described again here one by one.

[0236] From Tables 4a and 4b, it can be seen that the higher reliability level corresponding to the first UWB signal indicates a higher reliability level of the estimated arrival time of the signal transmitted by the device in the UWB system, and therefore indicates a fragment signal estimated accordingly for a smaller number of UWB signals 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, the procedure of the method shown in Figure 6 optionally further includes the following steps:

[0238] S611: The transmitting device sends 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 shows the configuration of the first UWB signal.

[0240] For example, the first configuration information may be transmitted via a narrowband signal. Specifically, in this embodiment, in order to improve the accuracy of receiving the first UWB signal, the receiving device receives the first narrowband signal from the transmitting device before receiving the first UWB signal, 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, if the transmitting device is a distance measuring initiator device, the receiving device is a distance measuring responder device, and the polling signal transmitted by the initiator to the responder in the distance measuring control phase includes first configuration information, the first configuration information indicating 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 and information indicating the sequence used by the preamble of the first UWB signal. 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 may be carried in a narrowband signal transmitted in the control phase (e.g., a polling signal, response signal, or newly added narrowband signal transmitted in the control phase of the first measurement round).

[0242] In another possible implementation, if the first UWB signal is a UWB signal transmitted in the control phase of measurement round #1 following the first measurement round in the measurement process, the first configuration information does not need to be transmitted; for example, the configuration of a UWB signal transmitted in a previous measurement round may be used as the associated configuration of the first UWB signal; or the first configuration information may be carried in a 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 the receiving device determines the first indication information, it transmits the first indication information to the transmitting device, and 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 Figure 6 further includes the following steps.

[0244] S630: The receiving device sends 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 over a narrowband. In other words, the first indication information may be a narrowband signal. In a possible implementation, in this embodiment, the receiving device may transmit a predefined first information element carrying the first indication information to the transmitting device, including the first indication information within a predefined first information element (for example, the first information element is transmitted over a narrowband). The predefined first information element is an information element that can be parsed 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 indicating the address type of the device receiving the first information element, and the first address field indicating the address of the device receiving 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 the 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 receiving the FFNE IE. The address size specifier field may also have an alternative name, provided that the address type of the device receiving the first information element is also indicated; this is not limited to the present application. The address type may include one or more of short addresses (i.e., address length of 2 octets) and long addresses (i.e., address length of 8 octets). Optionally, the indication rules are: 00 indicates no address, i.e., 0 octets; 01 indicates that it is reserved; 10 indicates a short address, i.e., two octets corresponding to 16 bits; and 11 indicates a long address, i.e., 8 octets corresponding to 64 bits. This matches the specifications of the previous generation UWB standard, IEEE 802.15.4z.

[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, the receiving device may broadcast the first information element after it has generated it.

[0249] In another possible implementation, the receiving device may directly transmit 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 first indication information to the transmitting device according to the source address of the first UWB signal it received.

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

[0252] For example, the higher layer of the transmitting device's protocol configures an FFNE IE and forwards the FFNE IE to the transmitting device's MAC layer.

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

[0254] In possible implementations, the newly added FFNE IE can be transmitted over a narrowband frequency range.

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

[0256] To make it easier to understand, the newly added FFNE IE will be explained 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, as can be seen from Table 6 below, 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 values 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 a data type IE.

[0259] Optionally, the message carrying the first indication information may be referred to as a UWB block number feedback message, which is a narrowband signal. In possible implementations, the receiver device's response (Resp) message for the polling message and the UWB block number feedback message fed back by the receiver device to the transmitter device may be contained within the same response message. That is, the receiver device does not need to respond immediately after receiving the polling message, but responds to both the polling message and the UWB test block by using a single message after receiving the first UWB signal to determine the first number of fragment signals of the second UWB signal. This is applicable to scenarios where a fast bidirectional narrowband handshake connection is not required between the transmitter and receiver devices.

[0260] For example, in a ranging slot after the transmitting and receiving devices have completed polling (Poll) initiation and response (Resp) respectively, the transmitting device sends a UWB (e.g., a first UWB signal) to the receiving device for testing (training) purposes. In other words, the receiving device's Resp message and the UWB block number feedback message that the receiving device feeds back to the initiator are two different messages. That is, after receiving the polling message, the receiving device may respond to the polling message, then receive the first UWB signal, determine a first number of fragments of the second UWB signal, and then send first indication information. This is applicable to scenarios where a fast bidirectional handshake connection needs to be performed between the initiator and responder.

[0261] The above merely illustrates, using an example, how a receiving device transmits the first indication information to a transmitting device, and should not constitute any limitation on the scope of protection of this application. In this embodiment, the method by which the receiving device transmits the first indication information to the transmitting device is not limited, provided that the first indication information can be transmitted to the transmitting device.

[0262] Optionally, after receiving the first indication information, the transmitting device may determine the first number of second UWB signal fragments expected by the receiving device. Alternatively, the transmitting device may use the second indication information to notify the receiving device of the second number of second UWB signal fragments expected by the transmitting device, or the transmitting device may use the second indication information to notify the receiving device of the fourth number of second UWB signal fragments expected by the transmitting device.

[0263] In this embodiment, the transmitting device determines the number of 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 decision based on a first number of fragment signals of a second UWB signal indicated by the received first indication information.

[0265] In Method 1, the procedure shown in Figure 6 further includes the following steps:

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

[0267] In possible implementations, 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 first round of measurement phase, the transmitting device performs the UWB measurement procedure based on the first number.

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

[0269] In other possible implementations, the second number is different from the first number. For example, the criteria factors that influence the determination of the second number by the transmitting device include, but are not limited to, the following:

[0270] (a) A first number that is fed back by multiple receiving devices when multiple receiving devices exist. For example, if the first numbers fed back by multiple receiving devices are different, the transmitting device uses the largest first number as the second number.

[0271] For example, when multiple transmitting devices are present, for how each transmitting device determines the second number of fragments of the second UWB signal, please refer to the aforementioned example where one transmitting device corresponds to multiple receiving devices. In other words, the example where multiple transmitting devices correspond to multiple receiving devices can be understood as multiple examples where one transmitting device corresponds to multiple receiving devices. Further details will not be explained here.

[0272] (b) Trust level history information of UWB signals from previous 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 in order 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 requires 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, if a receiving device feeds back a response (Resp) message to the transmitting device after sending a fifth UWB signal, the Resp message will include not only a response to the polling but also the first indication information that needs to be fed back to the transmitting device. It can be understood that the Resp message and the UWB block number feedback message fed back to the initiator by the receiving device will be combined.

[0282] Optionally, in Method 2, since the UWB test signal needs to be exchanged between the transmitting and receiving devices, the polling signal may be used to schedule and indicate the transmission order of the UWB test signal and narrowband signal between the transmitting and receiving devices during the distance measurement control phase.

[0283] For example, the polling signal indicates a slot occupied for transmitting a first UWB signal, a first indication information, a 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 to be transmitted in the measurement phase based on the narrowband signal (e.g., first indication information) and / or the received wideband signal (e.g., fifth UWB signal) responded by the receiving device.

[0286] For example, the transmitting device determines the number of fragment signals in the second UWB signal based on the first indication information received. This is similar to step S621, and will not be explained in detail again here.

[0287] In another example, the transmitting device determines the number of fragments of the second UWB signal transmitted during the measurement phase based on the received broadband signal (e.g., a fifth UWB signal). For example, the fifth UWB signal is used to determine the fifth number of fragments of the second UWB signal, and the transmitting device determines that the number of fragments 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 to be transmitted during the measurement phase based on the first indication information received and the received broadband signal (e.g., a fifth UWB signal).

[0289] In possible implementations, a fifth UWB signal is used to determine the fifth number of fragments of the second UWB signal. Specifically, in scheme 2, the transmitting device may ultimately determine the fourth number of fragments of the second UWB signal to be transmitted in the measurement phase (e.g., the ranging phase or the sensing phase) for measurement purposes by referring to the first number of fragments of the second UWB signal indicated by the first indication information and the fifth number of fragments of the second UWB signal determined by the transmitting device based on the fifth UWB signal.

[0290] For example, the transmitting device may use the greater of the first number of fragments of the second UWB signal and the fifth number of fragments of the second UWB signal as the fourth number of fragments of the second UWB signal; or, the transmitting device may use the average of the first number of fragments of the second UWB signal and the fifth number of fragments of the second UWB signal as the fourth number of fragments of the second UWB signal. In this embodiment, it should be understood that, in the procedure for determining the fourth number of fragments of the second UWB signal, the transmitting device is not limited to how it determines the fourth number of fragments of the second UWB signal based on the first number of fragments of the second UWB signal and the fifth number of fragments of the second UWB signal, provided that the transmitting device takes into account the first indication information and / or the fifth UWB signal to be received. The transmitting device may use the second indication information to inform the receiving device of the number of fragments of the second UWB signal that it expects. The procedure shown in Figure 6 further includes the following steps:

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

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

[0293] In accordance with Method 1, the second indication information indicates the second number of fragment signals of the second UWB signal; or, in accordance with Method 2, the second indication information indicates the fourth number of fragment signals of the second UWB signal.

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

[0295] For example, the second indication information is carried in a notification message, which 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 to the embodiments of this application. The message carrying the second indication information may be referred to as a notification message or may have a different name.

[0297] Optionally, notification messages may be included within Range Control Messages (RCMs).

[0298] In possible implementations, the RCM still uses information elements defined in the previous generation IEEE 802.15.4z standard. The RCM is for the basic configuration and scheduling indication of ranging measurements and includes, but is not limited to, scheduling and indication of the transmission order of ranging-involved devices, configuration of ranging round parameters, configuration of ranging block structure parameters, and configuration of UWB channels and preambles for ranging. In this implementation, some information elements in existing RCMs are reused to schedule and indicate the transmission order of fragment signals of the UWB signal. This may improve backward compatibility of the solution.

[0299] In another possible implementation, the RCM may be a newly defined message containing one or more informational elements, intended for the basic configuration and scheduling indication of the UWB signal during the measurement phase.

[0300] No limitations are imposed on the RCM in this embodiment, and all messages that may be for the basic configuration of fragment signals of the UWB signal in the measurement phase and for scheduling indication are included in the scope of protection of this application. For example, the RCM in this embodiment may be a message that includes one or more information elements defined in an existing protocol and newly added information elements.

[0301] Similar to the first indication information described above, in a possible implementation of this embodiment, the second indication information may be carried by the transmitting device in a predefined second information element and transmitted to the receiving device, the second information element further including a second address size specifier field and a second address field, the second address size specifier field indicating the address type of the device receiving the second information element and the second address field indicating the address of the device receiving the second information element.

[0302] The format of the second information element is the same as that of the first information element, and we will not explain the details again here.

[0303] For example, the parameter configurations of the first UWB signal (and / or fifth UWB signal) and the second UWB signal may differ. For example, parameters such as the type and length of the preamble may differ. The initiator may update the configuration of the preamble of the second UWB signal (and / or fifth UWB signal), which may include, but is not limited to, updates to 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 Figure 6 further includes the following steps.

[0304] S632: The transmitting device sends second configuration information to the receiving device, or the receiving device receives second configuration information from the transmitting device.

[0305] The second configuration information describes 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 possible implementations, the second narrowband signal and the second indication information constitute a single narrowband signal. It can be understood that if the second narrowband signal carrying the second configuration information and the narrowband signal carrying the second indication information (e.g., a UWB block number feedback message) constitute a single narrowband signal, the signaling transmission time can be reduced and effectiveness can be guaranteed. In the procedure shown in Figure 6, the receiving device may be a measurement initiator device or a measurement responder device. The following describes the procedure of the signaling transmission method provided in this application when the receiving device plays a different role in the ranging process, with reference to specific examples.

[0307] Example 1: In a 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. The control device can be understood as a device for determining the relevant parameters in the ranging procedure.

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

[0309] Stage 1: The initiator device sends 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 (e.g., 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 Figure 6.

[0312] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0313] Stage 3: In the distance measurement and control phase, the initiator device transmits the first UWB signal to the responder device.

[0314] For a related explanation of the first UWB signal, please refer to the explanation of the first UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

[0315] Stage 4: The responder device sends the first indication information to the initiator device.

[0316] For a related explanation of the first indication information, please refer to the explanation of the first indication information in the embodiment shown in Figure 6. Further details will not be explained here.

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

[0318] Stage 5: The initiator device sends the second indication information to the responder device.

[0319] For a related explanation of the second indication information, please refer to the explanation of the second indication information in the embodiment shown in Figure 6. Further details will not be explained here.

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

[0321] For a related explanation of the second narrowband signal, please refer to the explanation of the second narrowband signal in the embodiment shown in Figure 6. Further details will not be explained here.

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

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

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

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

[0326] Stage 1: The initiator device sends 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 (e.g., 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 can be understood as the first narrowband signal in the embodiment shown in Figure 6.

[0329] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0330] Stage 3: In the distance measurement and control phase, the responder device transmits the first UWB signal to the initiator device.

[0331] Stage 4: The initiator device sends the first indication information to the responder device.

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

[0333] For a related explanation of the second narrowband signal, please refer to the explanation of the second narrowband signal in the embodiment shown in Figure 6. Further details will not be explained here.

[0334] After steps 1 through 5, the initiator and responder devices may transmit the UWB ranging signal based on a determined number of fragment signals of the UWB ranging signal and parameters configured using a second narrowband signal, in order to perform subsequent steps of UWB ranging.

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

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

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

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

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

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

[0341] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0342] Stage 3: In the distance measurement and control phase, the initiator device transmits the first UWB signal to the responder device.

[0343] Stage 4: The responder device sends the first indication information to the control device.

[0344] For a related explanation of the first indication information, please refer to the explanation of the first indication information in the embodiment shown in Figure 6. Further details will not be explained here.

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

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

[0347] The control device determines whether to transmit a second UWB signal based on a first number of blocks. If the control device decides to transmit a second UWB signal based on the first number of blocks, it sends indication information #1 to the receiving and transmitting devices. For example, information element #1 is broadcast, and information element #1 contains indication information #1. In another example, information elements #2 and #3 are sent to the receiving and transmitting devices, respectively, and information elements #2 and #3 each contain indication information #1.

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

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

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

[0351] Specifically, Figures 7(a) to 7(c) correspond to an example in which the transmitting device determines the number of fragment signals of the second UWB signal based on first indication information transmitted by the receiving device. As can be seen from the procedure shown in Figure 6, the transmitting device may further determine the number of fragment signals of the second UWB signal based on first indication information transmitted by the receiving device and / or a UWB test signal transmitted by the receiving device. Below, using an example in which the transmitting device is a distance measuring initiator device, the receiving device is a distance measuring responder device, and the initiator device is a control device, a specific procedure of the embodiment described in Figure 6 will be explained in which the transmitting device determines the number of fragment signals of the second UWB signal based on first indication information transmitted by the receiving device and / or a UWB test signal transmitted by the receiving device.

[0352] Possible implementations include the following steps:

[0353] Stage 1a: The initiator device sends a polling signal to the responder device.

[0354] For example, the polling signal indicates the transmission sequence of UWB test signals and narrowband signals between the initiator device and the responder device during the distance measurement control phase.

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

[0356] Stage 2a: In the distance measurement and control phase, the initiator device transmits a first UWB signal to the responder device.

[0357] For a related explanation of the first UWB signal, please refer to the explanation of the first UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

[0358] Stage 3a: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0359] For example, the responder device's response (Resp) message to a polling message, and the UWB block number feedback message that the responder device feeds back to the initiator device, are included in the same response message.

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

[0361] For a related explanation of the fifth UWB signal, please refer to the explanation of the fifth UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

[0363] For a related explanation of the second indication information, please refer to the explanation of the second indication information in the embodiment shown in Figure 6. Further details will not be explained here.

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

[0365] For a related explanation of the second narrowband signal, please refer to the explanation of the second narrowband signal in the embodiment shown in Figure 6. Further details will not be explained here.

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

[0367] The aforementioned stages 1a through 6a are shown in Figure 7(d). Note that the order of stages 1a through 6a is not limited.

[0368] Another possible implementation includes the following steps:

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

[0370] For example, the polling signal indicates the transmission sequence of UWB test signals and narrowband signals between the initiator device and the responder device during the distance measurement control phase.

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

[0372] Stage 2b: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0373] Stage 3b: In the distance measurement and control phase, the initiator device transmits a first UWB signal to the responder device.

[0374] For a related explanation of the first UWB signal, please refer to the explanation of the first UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

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

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

[0378] For a related explanation of the fifth UWB signal, please refer to the explanation of the fifth UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

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

[0382] For a related explanation of the second narrowband signal, please refer to the explanation of the second narrowband signal in the embodiment shown in Figure 6. Further details will not be explained here.

[0383] The aforementioned stages 1b through 6b are shown in Figure 7(e).

[0384] Another possible implementation includes the following steps:

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

[0386] For example, the polling signal indicates the transmission sequence of UWB test signals and narrowband signals between the initiator device and the responder device during the distance measurement control phase.

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

[0388] Stage 2c: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0389] Stage 3c: In the distance measurement and control phase, the initiator device transmits the first UWB signal to the responder device.

[0390] For a related explanation of the first UWB signal, please refer to the explanation of the first UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

[0392] For a related explanation of the fifth UWB signal, please refer to the explanation of the fifth UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

[0394] 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. In addition, the responder device first sends the Resp message and then feeds back the UWB block number feedback message. This is applicable to scenarios where the responder device needs more time to process the UWB test signal from the initiator device.

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

[0396] For a related explanation of the second indication information, please refer to the explanation of the second indication information in the embodiment shown in Figure 6. Further details will not be explained here.

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

[0398] For a related explanation of the second narrowband signal, please refer to the explanation of the second narrowband signal in the embodiment shown in Figure 6. Further details will not be explained here.

[0399] The aforementioned stages 1c through 6c are shown in Figure 7(f).

[0400] Another possible implementation includes the following steps:

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

[0402] For example, the polling signal indicates the transmission sequence of UWB test signals and narrowband signals between the initiator device and the responder device during the distance measurement control phase.

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

[0404] Stage 2d: In the distance measurement and control phase, the initiator device transmits a first UWB signal to the responder device.

[0405] For a related explanation of the first UWB signal, please refer to the explanation of the first UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

[0407] Stage 4d: The responder device responds to the polling signal by sending a response signal to the initiator device.

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

[0409] For a related explanation of the fifth UWB signal, please refer to the explanation of the fifth UWB signal in the embodiment shown in Figure 6. Further details will not be explained again here.

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

[0411] For a related explanation of the second indication information, please refer to the explanation of the second indication information in the embodiment shown in Figure 6. Further details will not be explained here.

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

[0413] For a related explanation of the second narrowband signal, please refer to the explanation of the second narrowband signal in the embodiment shown in Figure 6. Further details will not be explained here.

[0414] The aforementioned stages 1d through 6d are shown in Figure 7(g).

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

[0416] In addition, Figures 7(d) to 7(g) show an example where the initiator device is a control device. When the responder device is a control device, the initiator device must return to the responder device the fifth number of UWB signal fragments determined based on the fifth UWB signal, and the responder device finally determines the number of UWB signal fragments based on the first UWB signal and the received information indicating the fifth number, and notifies the initiator device using a notification message.

[0417] The embodiments described above are explained using a one-to-one example, that is, one initiator device and one responder device. Note that the signaling transmission method shown in Figure 6 can be extended to one-to-many or many-to-many examples, that is, one initiator device and multiple responder devices, or multiple initiator devices and multiple responder devices.

[0418] For example, a one-to-many scenario is shown in Figure 7(h).

[0419] Polling messages in the ranging control phase may be used to schedule and indicate the transmission sequence of multiple UWB test signals and multiple narrowband signals between the initiator device and multiple responder devices during the ranging control phase.

[0420] For example, a slot is shown that is occupied by an initiator device to transmit UWB test signals and narrowband signals, and a slot is shown that is occupied by multiple responder devices to transmit multiple UWB test signals and multiple narrowband signals.

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

[0422] Optionally, notification messages in the distance measurement control phase may be used instead to schedule and indicate the transmission sequence of multiple second UWB signal fragments between the initiator device and multiple responder devices in the subsequent measurement phase.

[0423] For example, a notification message indicates a slot occupied by an initiator device and multiple responder devices to transmit a fragment signal.

[0424] The following example illustrates how an initiator device determines the number of fragment signals of the second UWB signal transmitted during the measurement phase in a one-to-many scenario.

[0425] There are N responder devices, and the number of fragment signals generated by each responder device is F1, F2...F in order. N Let's assume that it is estimated to be this.

[0426] In the case where the transmitting device determines the number of fragment signals of the second UWB signal based on the number of fragment signals fed back by the responder 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 the case where the transmitting device determines the number of fragment signals of the second UWB signal based on the number of fragment signals fed back by the responder device and the number of fragment signals estimated by the transmitting device,

[0429] Corresponding to the UWB test signals (for example, 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 ) That's it.

[0430] In the 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 above-described 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] As can be seen from the above, in the embodiment shown in Figure 6, the number of UWBs can be estimated in the distance measurement control phase based on the quality of the UWB test signal. Compared to existing solutions in which estimation is performed based on a narrowband NB signal, this solution is more accurate, reduces the possibility of misconfiguring the number of UWBs, and avoids or reduces the possibility of reduced system efficiency.

[0432] In addition, the embodiment shown in Figure 6 can avoid or reduce the possibility of improperly configured ON time for the receiver of the receiving / transmitting device, further avoid or reduce the possibility of excessively fast power consumption because the receiving / transmitting device cannot effectively sleep, and further avoid or reduce the possibility of reduced operating time for the receiving / transmitting device.

[0433] In addition, this invention further provides an alternative signaling transmission method to adjust the number of UWBs to an appropriate number in time based on the actual measurement effect of the current ranging round. This avoids a lot of wasted time in subsequent sequential ranging processes and improves system efficiency. The signaling transmission method will be described in detail below with reference to the attached drawings.

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

[0435] Figure 8 is a schematic flowchart of another signaling transmission method according to the present invention. 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 the UWB signal transmitted in the current measurement round for measurement (e.g., detection or ranging). The UWB signal is divided into multiple fragment signals for transmission in the transmission process. The transmitting device is the device that receives the multiple 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 in the current UWB signal is no longer appropriate, and that the number of fragment signals in the UWB signal needs to be changed (or updated).

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

[0440] For example, the transmitting device determines third indication information based on the quality of any of the received fragment signals. For a specific method of determining the number of fragment signals of the UWB signal to be transmitted based on the quality of the UWB signal, please refer to the description of the "step of determining first indication information based on the first UWB signal" in the embodiment shown in Figure 6. Further details will not be explained here.

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

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

[0443] The above is merely an example illustrating how third indication information is determined based on fragment signals, and should not constitute any limitation on the scope of protection of this application.

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

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

[0446] Similar to the first indication information described above, 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 including a third address size specifier field and a third address field, the third address size specifier field indicating the address type of the device receiving the third information element and the third address field indicating the address of the device receiving the third information element.

[0447] The format of the third information element is the same as that of the first information element, and we will not explain the details again here.

[0448] Optionally, the transmitting device may send second information to the control device instructing it to change the number of fragment signals in the third UWB signal. Optionally, the procedure of the method shown in Figure 8 further includes the following steps:

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

[0450] The second piece of information indicates that the number of fragment signals in the third UWB signal has changed. For example, the second piece of information can be triggered by using a Rangeing Change Request Information Element (RCR IE).

[0451] In possible implementations, the RCR IE still uses information elements defined in the previous generation IEEE 802.15.4z standard, and the RCR IE is intended to trigger range measurement change requests, including but not limited to changes in the range measurement round parameter configuration and changes in the range measurement block structure. In this implementation, existing information elements are reused to indicate changes in the number of fragment signals in the UWB signal. This may improve backward compatibility of the solution.

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

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

[0454] For example, the second piece of information may be transmitted through a narrowband, and the second piece of information may be a narrowband signal.

[0455] Specifically, after receiving the third indication information, the control device may use the first information to notify the transmitting device whether it agrees to change the number of fragment signals in the third UWB signal. The procedure of the method shown in Figure 8 further includes the following steps.

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

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

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

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

[0460] For example, the first piece of information is acknowledgment (ACK) information.

[0461] Optionally, in this implementation, the control device may, after transmitting acknowledgment information, further transmit a fourth indication information to indicate a third number of fragment signals of the third UWB signal; or, further transmit a fourth indication information to indicate a fourth number of fragment signals of the third UWB signal, the fourth number being different from the third number.

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

[0463] Specifically, in this implementation, the control device may transmit a fourth indication to both the transmitting and receiving devices, which can then transmit the UWB signal based on the modified number of UWB signal fragments. Optionally, the procedure of the method shown in Figure 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 may be transmitted through a narrowband, and the fourth indication information may be a narrowband signal.

[0466] Similar to the first indication information described above, in a possible implementation of this embodiment, the fourth indication information may be carried by the transmitting device in a predefined fourth information element and transmitted to the control device, the fourth information element further including a fourth address size specifier field and a fourth address field, the fourth address size specifier field indicating the address type of the device receiving the fourth information element and the fourth address field indicating the address of the device receiving the fourth information element.

[0467] The format of the fourth information element is the same as that of the first information element, and we will not explain the details again here.

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

[0469] In another example, the control device sends a fourth information element #1 to the transmitting device, where the fourth address size specifier field and / or the fourth address field within the fourth information element #1 indicate that the device receiving the fourth information element #1 is the transmitting device. The fourth information element #1 contains fourth indication information. In addition, the control device sends a fourth information element #2 to the receiving device, where the fourth address size specifier field and / or the fourth address field within the fourth information element #2 indicate that the device receiving the fourth information element #2 is the receiving device. The fourth information element #2 contains fourth indication information.

[0470] In another possible implementation, the first piece of information indicates that there is no agreement to update the number of fragment signals in the third UWB signal.

[0471] In this embodiment, the case where the control device agrees to update the number of fragment signals of the third UWB signal is primarily considered, and it should be understood that the case where the control device does not agree to update the number of fragment signals of the third UWB signal is not described in this embodiment.

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

[0473] In this implementation, after receiving the fourth indication information, the transmitting and receiving devices may transmit a third UWB signal in the second round measurement phase based on the modified number of fragment signals, with the second round being a measurement round following the first round. An inappropriate number of fragment signals can be adjusted in time to an appropriate number of fragment signals based on the actual measurement effect of the current ranging round. This avoids a lot of wasted time in subsequent sequential ranging processes and improves system efficiency. In addition, this implementation can avoid or reduce the possibility of improperly configured receiver on-times in the receiving / transmitting devices, further avoid or reduce the possibility of excessively fast power consumption because the receiving / transmitting devices cannot sleep effectively, and further avoid or reduce the possibility of reduced operating time of the receiving / transmitting devices. Note that the fact that the second round is a measurement round following the first round can be understood as the second round being performed after the first round has finished.

[0474] After the first round is completed, the execution of the second round will include the following two cases:

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

[0476] Case 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 is completed. In other words, there may be a certain time interval between the second round and the first round. For example, there may be another ranging round between the second round and the first round. It can be understood that the duration between the end of the first round and the start of the second round is greater than a predetermined threshold.

[0477] The preset threshold values ​​are not limited to the embodiments of this application. For example, in Example 2, there may be intervals of several round durations between the end of the first round and the start of the second round. These intervals may be used in other ranging processes or may be idle.

[0478] For example, in Example 2, the interval duration between the end of the first round and the start of the second round being greater than a preset threshold includes the fact that the second round and the first round are not in the same distance measurement block. For example, the first round is a distance measurement round in the current distance measurement block, and the second round is a distance measurement round in the next distance measurement block (e.g., a distance measurement block adjacent to the current distance measurement block). In this case, there is an interval of several round durations between the second round and the first round. Some of these round intervals may be used in other distance measurement processes or may be idle. In another example, the first round may be a distance measurement round in the current distance measurement block, and the second round may be a distance measurement round in a subsequent distance measurement block (e.g., a distance measurement block that is at least one distance measurement block other than the current distance measurement block).

[0479] The aforementioned distance measurement block can be understood as a time length that includes one or more distance measurement rounds.

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

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

[0482] In this implementation, the transmitting and receiving devices may, after receiving the fourth indication information, transmit a third UWB signal in the second round measurement phase based on the number of modified fragment signals, where the second round is the measurement round following the first round; or, after receiving the fourth indication information, the transmitting and receiving devices may transmit a third UWB signal after the second point in the first round measurement phase based on the number of modified fragment signals. An inappropriate number of fragment signals can be adjusted in time to an appropriate number of fragment signals based on the actual measurement effect of the current ranging round. This avoids wasting a lot of time in the remaining time of the current ranging round measurement phase and in subsequent continuous ranging processes, improving system efficiency. In addition, this implementation can avoid or reduce the possibility of improperly configured on-times for the receivers of the receiving / transmitting devices, further avoid or reduce the possibility of excessively rapid power consumption because the receiving / transmitting devices cannot effectively sleep, and further avoid or reduce the possibility of reduced operating duration of the receiving / transmitting devices. In the procedure shown in Figure 8, the receiving device may be a measurement initiator device or a measurement responder device; or the initiator device and control device may be the same device, and the responder device and control device may be the same device. Below, the procedure of the signaling transmission method provided in this application when the receiving devices play 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 also included. The control device can be understood as a device for determining relevant parameters in the ranging procedure.

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

[0485] Stage 1: The initiator device sends a polling signal to the responder device.

[0486] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0487] Stage 3: Transmit UWB ranging signals between the initiator device and the responder device and perform ranging.

[0488] For distinction, the UWB distance measurement signal transmitted by the initiator device to the responder device during the distance measurement phase is shown as the fourth UWB signal #1, and the UWB distance measurement signal transmitted by the responder device to the initiator device is shown as the fourth UWB signal #2. In Example 4, the fourth UWB signal in the embodiment shown in Figure 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] Stage 4: The initiator device transmits the second information and the third indication information to the control device.

[0491] Stage 4 includes two possibilities.

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

[0493] Possibility 2: As shown in Figure 9(b), the initiator device transmits second information and third indication information during the distance measurement reporting phase.

[0494] Stage 5: The control device sends the first piece of information to the initiator device.

[0495] Stage 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 transmits the fourth indication information to the initiator device and the responder device. Several possibilities are included below.

[0497] If 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, it may begin transmitting the fourth indication information to the initiator device and the responder device before the ranging phase of the next ranging round begins (for example, the ranging result reporting phase of the current ranging round or the control phase of the next ranging round). Figure 9(a) illustrates 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. The next ranging round may be a ranging round adjacent to the current ranging round, or it may be a ranging round that is at least one ranging round separate from the current ranging round.

[0498] If the initiator device transmits the second information and the third indication information during the distance measurement reporting phase of the current distance measurement round, the control device may transmit the fourth indication information to the initiator device and the responder device during the distance measurement reporting phase of the current distance measurement round; or, it may begin transmitting the fourth indication information to the initiator device and the responder device before the distance measurement phase of the next distance measurement round begins (for example, during the control phase of the next distance measurement round). Figure 9(b) illustrates an example in which the fourth indication information is transmitted to the initiator device and the responder device during the distance measurement result reporting phase of the current distance measurement round.

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

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

[0501] Example 5: The transmitting device is a range-measuring responder device, the receiving device is a range-measuring initiator device, and a control device is also included.

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

[0503] Stage 1: The initiator device sends a polling signal to the responder device.

[0504] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0505] Stage 3: Transmit UWB ranging signals between the initiator device and the responder device and perform ranging.

[0506] For distinction, the UWB distance measurement signal transmitted by the initiator device to the responder device during the distance measurement phase is shown as the fourth UWB signal #1, and the UWB distance measurement signal transmitted by the responder device to the initiator device is shown as the fourth UWB signal #2. In Example 5, the fourth UWB signal in the embodiment shown in Figure 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] Stage 4: The responder device transmits the second information and the third indication information to the control device.

[0509] Stage 4 includes two possibilities.

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

[0511] Possibility 2: As shown in Figure 10(b), the responder device transmits second information and third indication information during the distance measurement reporting phase.

[0512] Stage 5: The control device sends the first piece of information to the responder device.

[0513] Stage 6: The control device sends 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. Several possibilities are included below.

[0515] If the initiator device transmits second information and third indication information in the current ranging phase, the control device may transmit fourth indication information to the initiator device and responder device in the current ranging phase; or, it may begin transmitting fourth indication information to the initiator device and responder device before the ranging phase of the next ranging round begins (for example, the ranging result reporting phase of the current ranging round or the control phase of the next ranging round). Figure 10(a) illustrates an example in which fourth indication information is transmitted to the initiator device and responder device in the ranging result reporting phase of the current ranging round.

[0516] If the initiator device transmits the second information and the third indication information during the distance measurement reporting phase of the current distance measurement round, the control device may transmit the fourth indication information to the initiator device and the responder device during the distance measurement reporting phase of the current distance measurement round; or, it may begin transmitting the fourth indication information to the initiator device and the responder device before the distance measurement phase of the next distance measurement round begins (for example, during the control phase of the next distance measurement round). Figure 10(b) illustrates an example in which the fourth indication information is transmitted to the initiator device and the responder device during the distance measurement result reporting phase of the current distance measurement round.

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

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

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

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

[0521] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0522] Stage 3: Transmit UWB ranging signals between the initiator device and the responder device and perform ranging.

[0523] For distinction, the UWB distance measurement signal transmitted by the initiator device to the responder device during the distance measurement phase is shown as the fourth UWB signal #1, and the UWB distance measurement signal transmitted by the responder device to the initiator device is shown as the fourth UWB signal #2. In Example 4, the fourth UWB signal in the embodiment shown in Figure 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] Stage 4: The initiator device sends a third indication message to the responder device.

[0526] Stage 4 includes two possibilities.

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

[0528] Possibility 2: As shown in Figure 11(b), the initiator device transmits a third indication information during the distance measurement reporting phase.

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

[0530] For example, if the initiator device transmits a third indication in the current ranging phase, the responder device, after receiving the third indication, directly uses the modified number of fragment signals in the ranging phase of the current ranging round to perform ranging. Alternatively, the initiator and responder devices use the modified number of fragment signals in the next UWB ranging round to perform UWB ranging.

[0531] In another example, if the initiator device transmits a third indication during the distance measurement reporting phase, the initiator and responder devices use the modified number of fragment signals in the next UWB distance measurement round to perform UWB distance measurement.

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

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

[0534] Stage 1: The initiator device sends a polling signal to the responder device.

[0535] Stage 2: The responder device responds to the polling signal by sending a response signal to the initiator device.

[0536] Stage 3: Transmit UWB ranging signals between the initiator device and the responder device and perform ranging.

[0537] For distinction, the UWB distance measurement signal transmitted by the initiator device to the responder device during the distance measurement phase is shown as the fourth UWB signal #1, and the UWB distance measurement signal transmitted by the responder device to the initiator device is shown as the fourth UWB signal #2. In Example 4, the fourth UWB signal in the embodiment shown in Figure 8 is the fourth UWB signal #2.

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

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

[0540] Stage 4 includes two possibilities.

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

[0542] Possibility 2: As shown in Figure 12(b), the initiator device transmits second information and third indication information during the distance measurement reporting phase.

[0543] Stage 5: The responder device sends the fourth indication information to the initiator device.

[0544] Specifically, after the responder device receives the third indication information, it sends the fourth indication information to the initiator device. Several possibilities are included below.

[0545] If the initiator device transmits second information and third indication information in the current ranging phase, the responder device may transmit fourth indication information to the initiator device in the current ranging phase; or, it may begin transmitting fourth indication information to the initiator device before the ranging phase of the next ranging round begins (for example, the ranging result reporting phase of the current ranging round or the control phase of the next ranging round). Figure 12(a) illustrates an example in which fourth indication information is transmitted to the initiator device and the responder device in the ranging result reporting phase of the current ranging round.

[0546] If the initiator device transmits the second information and the third indication information during the distance measurement reporting phase of the current distance measurement round, the responder device may transmit the fourth indication information to the initiator device during the distance measurement reporting phase of the current distance measurement round; or, it may begin transmitting the fourth indication information to the initiator device before the distance measurement phase of the next distance measurement round begins (for example, during the control phase of the next distance measurement round). Figure 12(b) illustrates an example in which the fourth indication information is transmitted to the initiator device and the responder device during the distance measurement result reporting phase of the current distance measurement round.

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

[0548] Alternatively, in the ranging process, if the receiving device is a ranging responder device and the responder device is a 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 does not need to be determined based on third indication information transmitted by the initiator device. For example, after steps 1 and 3 are performed, the following steps are performed.

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

[0550] Stage 4a includes two possibilities.

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

[0552] Possibility 2: As shown in Figure 12(d), the responder device transmits a fourth indication during the distance measurement reporting phase.

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

[0554] The procedures shown in Figures 6 and 8 describe in detail how to determine the number of UWB signal fragments transmitted during the measurement phase based on the UWB test signal, and how to indicate the number of UWB signal fragments.

[0555] In possible implementations, the transmission device determining the number of UWB signal fragments transmitted during the measurement phase is a procedure that does not need to be triggered.

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

[0557] For example, the receiving device is a range-measuring responder device, and the transmitting device is a range-measuring initiator device. If, during the measurement reporting phase of the first round, the responder device needs to change the number of UWB signal fragments transmitted in the measurement phase of a subsequent round (e.g., the second round), the following information is required: Change request messages, the number of updated fragment signals (e.g., the FFNE IE message mentioned above), or information related to changes in the number of fragment signals in the UWB signal, etc. At least one of these is carried in a reporting message (e.g., a narrowband signal) related to the distance measurement result and returned to the transmitting device. The change request message instructs the number of fragment signals in the UWB signal to be changed. For example, the change request message may be the RCR IE described above.

[0558] In other words, information related to changes in the number of UWB signal fragments, and report messages returned by the responder device to the initiator device related to the distance measurement results, can be combined for reporting in a single message.

[0559] In another example, if, during the measurement phase of the first round, the receiving device needs to change the number of UWB signal fragments transmitted in the measurement phase of a subsequent round (e.g., the second round), the receiving device may send a change request message (e.g., a narrowband signal) to the transmitting device, which is used to request a change in the number of UWB signal fragments transmitted in the measurement phase of the subsequent round (e.g., the second round), and the change request message contains the following information: Information related to changes in the number of UWBs, such as change request messages, the number of updated fragment signals (e.g., the FFNE IE message mentioned above), or changes in the number of UWBs. It includes at least one of the following. The change request message instructs to change the number of fragment signals in the UWB signal. For example, the change request message may be the RCR IE described above.

[0560] In other words, information related to the number of UWB signal fragments transmitted during the measurement phase process, i.e., information related to the distance measurement results and reporting messages, does not need to be combined for transmission. For example, the order of transmission slots for change request messages, and the UWB signals sent from the receiving device to the transmitting device, can be swapped to make them applicable to different scenarios.

[0561] For example, a change request message might be sent after the receiving device has sent the UWB signal to the transmitting device, which is applicable in scenarios where the receiving device needs more time to process the fragmented UWB signal from the initiator. In another example, a change request message might be sent before the receiving device has sent the UWB signal to the transmitting device, which is applicable in scenarios where the receiving device needs to respond quickly to the transmitting device.

[0562] In addition, it should be noted that the aforementioned procedure for triggering an update of the number of UWB signal fragments by the receiving device is applicable to other scenarios; that is, the trigger procedure may be independent. For example, the method for determining the number of UWB signal fragments before the change request is not limited. If the receiving device needs to change the number of UWB signal fragments, the trigger procedure may be used to trigger an update of the number of UWB signal fragments.

[0563] For example, the method for determining the number of UWB signal fragments before a change request may be the aforementioned method for determining the number of UWB signal fragments based on a UWB test signal in the distance measurement control phase, or it may be another existing or future method for determining the number of UWB signal fragments.

[0564] For easier understanding, the procedure by which the receiving device triggers an update of the number of UWB signal fragments is described in detail with reference to Figures 12(e) through 12(g).

[0565] Possibility 1: The receiving device sends a change request message to the transmitting device during the measurement result reporting phase of the current measurement round, triggering an update to the number of UWB signal fragments in the next measurement round.

[0566] Possibility 1: As shown in Figure 12(e), the change request message may be carried in the reporting message related to the distance measurement result.

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

[0568] The examples shown in Figures 12(f) and 12(g) demonstrate that the order of the transmission slots for change request messages, and the UWB signals sent from the receiving device to the transmitting device, may be interchangeable.

[0569] In the procedure for triggering the update of the number of UWB signal fragments shown in Figures 12(e) to 12(g), the receiving device is a responder device and the transmitting device is an initiator device; or, the receiving device is an initiator device and the transmitting device is a responder device. In addition, in the examples shown in Figures 12(e) to 12(g), the transmitting device is a control device. Alternatively, the control device may be a third-party or receiving device, and the procedure is the same as in Figures 12(e) to 12(g), and will not be described in detail again.

[0570] Note that the procedure described above for triggering an update of the number of UWB signal fragments can be used in combination with the procedure described above for determining the number of UWB signal fragments.

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

The execution order of the processes should be determined based on their function and the internal logic of the processes, and should not be construed as any limitation on the processes of the implementation of the embodiments of this application.
