Method and device for transmitting signaling
[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 7, 2022, with application number 202210637088.2 and application name “Method and Device for Transmitting Signaling” and the Chinese patent application filed with the China Patent Office on July 5, 2022, with application number 202210783842.3 and application name “Method and Device for Transmitting Signaling”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The embodiments of the present application relate to the field of communications, and more specifically, to a method and apparatus for transmitting signaling. Background Art
[0003] Ultra-wideband (UWB) technology is a wireless communication (or ranging, sensing, etc.) technology that utilizes nanosecond-scale, non-sinusoidal, narrow pulse signals. Due to its narrow pulses and extremely low radiation spectral density, UWB systems offer advantages such as strong multipath resolution, low power consumption, and enhanced security.
[0004] For ranging or perception scenarios, the accuracy of the measurement or perception results is closely related to the signal bandwidth. The larger the signal bandwidth, the higher the accuracy of the perception or ranging results. It is possible to consider sending and receiving the reference signal used for ranging or perception through the UWB system, while transmitting other reference signals and / or data through a narrowband protocol. This processing method can be understood as UWB ranging or perception assisted by a narrowband protocol.
[0005] In current narrowband protocol-assisted UWB ranging methods, during the ranging control phase, the responding end roughly estimates the number of UWB ranging signal segments required for the ranging phase of the current UWB ranging round based on the power strength of the narrowband signal received from the initiating end. This can mislead the initiating end in configuring ranging parameters, reducing system efficiency. Therefore, improving the performance of narrowband protocol-assisted UWB ranging or sensing methods has become an urgent issue.

[0151] The technical solution in this application will be described below with reference to the accompanying drawings.
[0152] The embodiments of the present application can be applied to wireless personal area networks (WPANs) based on ultra-wideband (UWB) technology. Currently, WPANs adopt the IEEE 802.15 standard. WPANs can be used for communication between small-scale digital auxiliary devices such as phones, computers, and accessories, with an operating range generally within 10 meters. Technologies supporting WPANs include Bluetooth, ZigBee, ultra-wideband (UWB), infrared connection technology (IR) from the Infrared Data Association (IrDA), and home radio frequency (HomeRF). Those skilled in the art will readily appreciate that the various aspects of the present application can be extended to other networks using various standards or protocols, such as wireless local area networks (WLANs), high-performance wireless LANs (HIPERLANs) (a wireless standard similar to IEEE 802.11, primarily used in Europe), wide area networks (WANs), and other currently known or later developed networks. From a network perspective, WPANs sit at the bottom layer of the overall network architecture, providing wireless connections between devices within a small area—point-to-point, short-range connections—and can be considered short-range wireless communication networks. Based on different application scenarios, WPANs are categorized into high-rate (HR) WPANs and low-rate (low) WPANs. HR WPANs can support various high-rate multimedia applications, including high-quality audio and video distribution, and multi-megabyte music and image file transfers. LR WPANs can be used for general daily tasks.
[0153] In a WPAN, devices can be categorized as full-function devices (FFDs) and reduced-function devices (RFDs) based on their communication capabilities. FFDs can communicate with each other and with each other. RFDs cannot communicate directly with each other and can only communicate with one FFD or forward data through an FFD. The FFD associated with an RFD is called the coordinator of that RFD. A coordinator can also control and associate with multiple FFDs. A coordinator is also called a control node. Each ad hoc network can have multiple coordinators. RFDs are primarily used for simple control applications, such as light switches and passive infrared sensors. They transmit relatively small amounts of data, consume minimal transmission and communication resources, and are therefore relatively inexpensive. A coordinator can also be called a personal area network (PAN) coordinator. A PAN coordinator can be understood as a type of coordinator, and a PAN coordinator can also be referred to as the central control node of a PAN. An FFD can serve as a PAN coordinator or coordinator, while an RFD cannot. The PAN coordinator is the master control node of the entire network, and each ad hoc network can only have one PAN coordinator, which has membership management, link information management, and packet forwarding functions. Optionally, the device in the embodiment of the present application can be a device that supports multiple WPAN standards such as 802.15.4a and 802.15.4z, as well as 802.15.4ab or later versions.

[0155] In an embodiment of the present application, the above-mentioned device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU) and a memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through a process, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system or a windows operating system. The application layer includes applications such as a browser, an address book, a word processing software, and an instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application. As long as it is possible to communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be an FFD or RFD, or a functional module in the FFD or RFD that can call and execute a program.
[0156] In addition, various aspects or features of the present application can be implemented as methods, apparatus, or articles of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier, or medium. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes, etc.), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memories (EPROMs), cards, sticks, or key drives, etc.). In addition, the various storage media described herein may represent one or more devices and / or other machine-readable media for storing information. The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing, and / or carrying instructions and / or data.
[0157] The embodiments of the present application may also be applicable to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X) network.

[0158] The above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited to this. It is described uniformly here and will not be repeated below.
[0159] Figure 1 is a schematic diagram of two application scenarios provided by the present application. In the system 101 shown in (A) of Figure 1, multiple FFD devices and multiple RFD devices form a star topology communication system, wherein one of the FFDs is a PAN controller. In the star topology communication system, the PAN controller transmits data with one or more other devices, that is, multiple devices can establish a one-to-many or many-to-one data transmission architecture. In the system 102 shown in (B) of Figure 1, multiple FFD devices and one RFD device form a peer-to-peer topology or mesh topology communication system, wherein one of the FFDs is a PAN controller. In the peer-to-peer topology communication system, a many-to-many data transmission architecture can be established between multiple different devices.
[0160] It should be understood that Figures 1(A) and 1(B) are simplified schematic diagrams for ease of understanding and do not limit the application scenarios of the present application. For example, the system 101 and / or the system 102 may also include other FFDs and / or RFDs. For another example, the PAN coordinator in the system 101 and / or the system 102 may also be a coordinator.
[0161] In order to facilitate understanding of the technical solutions of the embodiments of the present application, some terms or concepts that may be involved in the embodiments of the present application are first briefly described.
[0162] 1. UWB technology: A wireless communication / ranging / sensing technology that utilizes nanosecond-level, non-sinusoidal, narrow pulse signals, thus occupying a wide spectrum. Due to its narrow pulses and extremely low radiation spectral density, UWB systems offer advantages such as strong multipath resolution, low power consumption, and high confidentiality, facilitating coexistence with other systems, thereby improving spectrum utilization and system capacity.
[0163] With the Federal Communications Commission (FCC) approving UWB technology for civilian use in 2002, ultra-wideband (UWB) wireless communications have become a popular physical layer technology for short-range, high-speed wireless networks. Many world-renowned companies, research institutions, and standards organizations are actively engaged in the research, development, and standardization of UWB wireless communications technology. The Institute of Electrical and Electronics Engineers (IEEE) has incorporated UWB technology into its IEEE 802 series of wireless standards and has released the UWB-based WPAN standard IEEE 802.15.4a and its evolved version IEEE 802.15.4z. The development of the next-generation UWB WPAN standard 802.15.4ab is also underway.
[0164] Since UWB technology does not require the use of carriers in traditional communication systems, but instead transmits data by sending and receiving extremely narrow pulses of nanoseconds or less, it has very high requirements for the time synchronization of the transmitting and receiving devices. At the same time, due to its large communication bandwidth, the power consumption and complexity of the equipment are high when sending and receiving signals on ultra-wideband channels. Most UWB communication devices are battery-driven. The next generation standard hopes to further reduce the power consumption of the UWB system. Therefore, a narrowband signal-assisted method can be used to send and receive all signals except the reference signals for ranging and perception through a narrowband system, thereby reducing overall power consumption overhead.
[0165] 2. UWB signal power: Due to the large bandwidth of the ultra-wideband system, in order to reduce its interference with other narrowband devices during operation, the FCC has strictly limited the power spectral density of UWB signals. According to the Code of Federal Regulations (CFR), there are two main rules:
[0166] Rule 1: The maximum power spectral density (PSD) of the transmitted UWB signal, averaged over one millisecond, must not exceed 41.3 dBm per MHz.
[0167] Rule 2: The maximum power of the transmitted UWB signal within any 50M bandwidth cannot exceed 1 milliwatt.
[0168] Rule 1 limits the total energy transmitted by UWB within 1 millisecond (for example, 37nJ at 500MHz bandwidth). However, by concentrating this energy and transmitting it in a shorter period of time, the instantaneous power of the transmitted signal is increased, thereby expanding the signal coverage and improving the signal-to-noise ratio of the received signal at the receiving end. Based on this, in some scenarios where increased transmit power is required, the transmitter will split the UWB signal to be transmitted into multiple segments, each of which is less than 1 millisecond in length, and then send only one of the segments within each millisecond.
[0169] For ease of understanding, the UWB signal is briefly introduced with reference to FIG2 , which is a schematic diagram of a UWB signal provided in an embodiment of the present application.
[0170] As shown in Figure 2, the transmitter splits the UWB signal into multiple segmented signals (e.g., UWB segmented signal #1, UWB segmented signal #2, UWB segmented signal #3, etc.). Each segmented signal is less than 1 millisecond in duration, and one segmented signal is transmitted within each millisecond. Each segmented signal is also a UWB signal.
[0171] In addition, in this application, a "segmented signal" may also be referred to as a "block signal," "short signal," "partial signal," "segment," or "block," etc. The name of the segmented signal is not limited and can be used to identify that a UWB signal is split into multiple UWB signals, where each of the multiple split UWB signals has a duration of less than 1 millisecond, and a split UWB signal is sent within each millisecond. Optionally, the multiple segmented signals obtained by splitting the UWB signal may be identical. For example, the multiple segmented signals obtained by splitting the UWB signal may be preambles of the same configuration, where the preambles of the same configuration include, but are not limited to, the length of the preamble, the sequence used for the preamble, etc.
[0172] As can be seen from the above, splitting the UWB signal into multiple segments for segmented transmission can increase the instantaneous power of the UWB signal, but it cannot be increased indefinitely. Rule 2 actually limits the power increase multiple of UWB segmented transmission.
[0173] For example, in this application, UWB segmented transmission may also be referred to as multi-millesecond transmission (MMS).
[0174] 3. Impulse Radio Ultra Wideband (IR-UWB) System: Due to the large bandwidth of ultra-wideband systems, their devices need to have ultra-high-speed data transmission and reception capabilities. However, the spectrum efficiency of the pulse-based IR-UWB system is low. When transmitting the same information, the power consumption overhead required by the IR-UWB solution is much higher than that of other narrowband short-range protocols (such as Bluetooth or ZigBee).
[0175] 4. Ranging or perception: For ranging or perception scenarios, the accuracy of the measurement or perception results is related to the signal bandwidth. The larger the signal bandwidth, the higher the accuracy of the perception or ranging results. Therefore, it is possible to consider transmitting and receiving the reference signal used for ranging or perception through the UWB system, while transmitting other reference signals and / or data through a narrowband protocol, so as to ensure the accuracy of ranging and perception and save power consumption. Among them, the perception involved in this application can be understood as the underlying perception technology of the Internet of Things technology architecture, which is the primary link for the Internet of Things to obtain information and realize object control; ranging can be understood as the measurement of the distance between devices, including but not limited to the distance measurement between two objects in the Internet of Things.
[0176] For example, the UWB technical solution combining narrow-band assisted UWB and multi-millisecond transmission in the present application may also be referred to as narrow-band assisted multi millisecond Ultra-wideband (NBA-MMS UWB).
[0177] For ease of understanding, the ranging and positioning system used in the above-mentioned ranging technology is briefly introduced in conjunction with Figure 3. Figure 3 is a schematic diagram of the architecture of the ranging and positioning system provided in an embodiment of the present application. As shown in Figure 3, the ranging and positioning system includes multiple devices (such as device 1 and device 2 as shown in Figure 3), which can be the devices involved in the embodiment of the present application, and each device includes at least a UWB module. Furthermore, the device may also include a narrowband communication module. Among them, either ranging positioning or communication can be performed between the UWB modules of device 1 and device 2. If a narrowband communication module is included in the device, data transmission can be performed between the narrowband communication modules of device 1 and device 2 through a wireless link.
[0178] In this application, the UWB module can be understood as a device, chip or system that implements UWB wireless communication technology; accordingly, the narrowband communication module can be understood as a device, chip or system that implements narrowband communication technology (such as Wi-Fi, Bluetooth, or Zigbee (Purple Bee Protocol)). In a device, the UWB module and the narrowband communication module can be different devices or chips. Of course, the UWB module and the narrowband communication module can also be integrated into one device or chip. The embodiments of this application do not limit the implementation of the UWB module and the narrowband communication module in the device. UWB technology enables communication devices to have high data throughput and high-precision positioning of the device.
[0179] The device involved in this application can be a wireless communication chip, a wireless sensor or a wireless communication terminal. For example, a user terminal, a user device, an access device, a subscriber station, a subscriber unit, a mobile station, a user agent, and a user equipment that support Wi-Fi communication functions, wherein the user terminal can include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, Internet of Things (IoT) devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), terminal, terminal equipment, portable communication devices, handheld devices, portable computing devices, entertainment devices, gaming devices or systems, global positioning system devices or any other suitable devices configured to communicate over a wireless medium. In addition, the device can support 802.15.4ab standard or the next generation standard of 802.15.4ab. The device can also support multiple standards such as 802.15.4a, 802.15.4-2011, 802.15.4-2015, and 802.15.4z. It can also support various 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 802.11be next generation.
[0180] 5. Figure of Merit (FoM) field: In the previous generation IEEE 802.15.4z standard and earlier UWB standards, the FoM field is used to evaluate the confidence of the ranging signal. Specifically, the FoM field is used to indicate the accuracy of the estimated arrival time of the ranging signal.
[0181] Exemplarily, the arrival time of the ranging signal is used to determine the ranging result, and the FoM field is used to indicate the accuracy of the estimated arrival time of the ranging signal. It can also be understood that the FoM field is used to evaluate the credibility of the ranging result. In this application, the FoM field can also be referred to as a ranging confidence field, which is used to indicate the ranging confidence.
[0182] Specifically, the ranging confidence field is shown in Table 1 below:

[0184] The specific content and meaning of the "Confidence" field in Table 1 are shown in Table 2 below.
[0185] Table 2: Confidence field contents
[0186] The higher the confidence value in Table 2, the more reliable the current ranging result. 'no FoM' in Table 2 means the current ranging result is incorrect or unusable.
[0187] 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 the ranging slot. A ranging round is divided into three phases: the ranging control phase, the ranging phase, and the ranging result reporting phase, as shown in Figure 4, which is a schematic diagram of 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, while in the IEEE 802.15.4ab standard currently under discussion, the ranging control phase can include more than one ranging slot.
[0188] It should be noted that the method for transmitting signaling provided in this application can be applied not only to UWB ranging assisted by a narrowband protocol, but also to UWB perception or other measurement processes assisted by a narrowband protocol. Therefore, the ranging control phase shown in Figure 4 of this application can be understood as a type of measurement control phase, the ranging phase can be understood as a type of measurement phase, and the ranging result reporting phase can be understood as a type of measurement result reporting phase. For example, when the method for transmitting signaling provided in this application is applied to a UWB perception process assisted by a narrowband protocol, the measurement control phase can be understood as the perception control phase, the measurement phase can be understood as the perception phase, and the measurement result reporting phase can be understood as the perception result reporting phase.
[0189] It should also be noted that the names of the different phases in the aforementioned single measurement round are merely examples and do not limit the scope of protection of this application. For example, the aforementioned measurement control phase can be understood as the phase for configuring the parameters required in the measurement round; another example, the aforementioned measurement phase can be understood as the phase for performing measurements; and another example, the aforementioned measurement result reporting phase can be understood as the phase for reporting measurement results, and can also be referred to as the end of the measurement phase.
[0190] For ease of understanding, the following briefly describes a narrowband protocol-assisted UWB ranging method with reference to Figure 5. Figure 5 is a schematic diagram of the UWB ranging method. Figure 5 includes an initiator and a responder. By way of example and not limitation, the initiator can be a device with communication capabilities in a WPAN (such as the FFD or RFD shown in Figure 1); similarly, the responder can also be a device with communication capabilities in a WPAN (such as the FFD or RFD shown in Figure 1).
[0191] In addition, the structures of the initiator and the responder may be the structures shown in device 1 or device 2 shown in FIG3 , for example, the initiator and the responder include a UWB module and a narrowband communication module.
[0192] As shown in Figure 5, the initiator and responder exchange narrowband (NB) signals to complete the configuration and synchronization required for UWB NBA-MMS ranging. For example, the initiator sends a narrowband poll signal (Poll), and the responder responds with a response signal (Resp) to complete the handshake. The Poll signal carries information including, but not limited to, one or more of the following: ranging round-related parameter configuration, ranging signal preamble parameter configuration (preamble length, preamble sequence, etc.), UWB packet type (SP0-SP3), device role, and time slot scheduling allocation.
[0193] During the ranging control phase, the responding end roughly estimates the number of UWB ranging signal segments required for the ranging phase of the current UWB ranging round based on the power strength of the NB signal received from the initiating end (e.g., if the NB signal power strength is high, the signal-to-noise ratio (SNR) is high, and the signal quality is good, a small number of segments are determined to be used; or if the NB signal power strength is low, the SNR is low, and the signal quality is poor, a large number of segments are determined to be used). The responding end then feeds back this roughly estimated number of UWB ranging signal segments to the initiating end. The initiating end then determines the number of UWB ranging signal segments required for the ranging phase based on the number of segments fed back by the responding end.
[0194] Specifically, after receiving the response frame, the initiator uses segmented transmission on the UWB channel to measure the round-trip time with the responder. After the measurement is completed, the responder sends the measurement result (report) to the initiator through the narrowband system.
[0195] The above describes the applicable scenarios of the embodiment of the present application in conjunction with FIG1 , briefly introduces the basic concepts involved in the present application, and briefly introduces a UWB ranging method in conjunction with FIG5 . This method has the following problems:
[0196] NB and UWB channels have different bandwidths and signal waveforms, resulting in significantly different channel conditions and varying degrees of channel attenuation. Specifically, UWB signals have ultra-short pulse durations in the nanosecond range, high temporal resolution, and a wide transmission bandwidth. In indoor multipath environments, UWB receivers can coherently increase the pulse energy received from each multipath component, providing gain for reception along a single path. Existing research shows that under indoor multipath conditions, the UWB received signal level strength can fluctuate within + / - 5dB relative to the average level strength. Therefore, UWB signals are less likely to experience deep fades and are effectively resistant to multipath fading.
[0197] In contrast, NB signals are more susceptible to multipath. Existing research shows that in indoor multipath conditions, the received NB signal strength can fluctuate by as much as -20 to -30 dB relative to the average. Therefore, NB signals are more likely to experience deep fades and are less resilient to multipath fading.
[0198] In summary, under the UWB ranging method shown in Figure 5, if the responding end uses the NB signal strength to roughly estimate the number of segmented signals of the UWB ranging signal required in the UWB ranging phase, serious distortion will occur, thereby misleading the initiating end to configure the parameters of the ranging phase, reducing system efficiency. For example, the initiating end may incorrectly configure a large number of segmented signals of the UWB ranging signal for the ranging phase, resulting in a long ranging time, affecting the access of other ranging users and the implementation of ranging tasks, increasing system latency, and reducing system efficiency. In addition, the incorrect configuration of the number of segmented signals of the UWB signal may cause the receiver on-time period of the receiving end / transmitting end device to be improperly configured, thereby causing the receiving end / transmitting end device to be unable to effectively sleep and consume power too quickly, affecting the working time of the receiving end / transmitting end device. In order to solve the problems existing in the above-mentioned UWB ranging method, the present application provides a method for transmitting signaling, which improves the accuracy of determining the number of segmented signals of the UWB signal by determining the number of segmented signals of the UWB signal transmitted in the measurement phase based on the UWB signal transmitted in the control phase. The following will describe in detail the method for transmitting signaling provided by this application with reference to the accompanying drawings.
[0199] The embodiments shown below do not specifically limit the specific structure of the execution subject of the method provided in the embodiments of the present application. As long as it is possible to communicate according to the method provided in the embodiments of the present application by running a program that records the code of the method provided in the embodiments of the present application, for example, the execution subject of the method provided in the embodiments of the present application can be a transceiver device, or a functional module in the transceiver device that can call and execute the program.
[0200] In order to facilitate understanding of the embodiments of the present application, the following explanations are made.
[0201] First, in this application, "used to indicate" can include direct indication and indirect indication. When describing that a certain information is used to indicate A, it can include that the information directly indicates A or indirectly indicates A, but it does not mean that the information must contain A.
[0202] The information indicated by the information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, it is also possible to use the arrangement order of each piece of information that is agreed in advance (for example, stipulated in the protocol) to achieve the indication of specific information, thereby reducing the indication overhead to a certain extent. At the same time, it is also possible to identify the common parts of each piece of information and indicate them uniformly to reduce the indication overhead caused by indicating the same information separately.
[0203] Second, the first, second, and various numerical numbers (e.g., "#1," "#2," etc.) shown in this application are merely for convenience of description and are used to distinguish between objects. They are not intended to limit the scope of the embodiments of this application. For example, they distinguish between different channels. They are not intended to describe a specific order or precedence. It should be understood that the objects described in this manner can be interchanged where appropriate to describe solutions beyond the embodiments of this application.
[0204] Third, in this application, "pre-configuration" may include pre-definition, such as protocol definition. This "pre-definition" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., including various network elements). This application does not limit the specific implementation method.
[0205] Fourth, the term "storage" used in the embodiments of this application may refer to storage in one or more memories. The one or more memories may be provided separately or integrated into an encoder or decoder, a processor, or a communication device. The one or more memories may also be provided in part separately and in part integrated into a decoder, a processor, or a communication device. The memory may be any type of storage medium, and this application is not limited thereto.
[0206] Fifth, the term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
[0207] Sixth, the "protocol" involved in the embodiments of the present application may refer to a standard protocol in the communication field, for example, it may include a WiFi protocol and related protocols used in future communication systems, and the present application does not limit this.
[0208] In the following, without loss of generality, the method for transmitting signaling provided by the embodiment of the present application is described in detail by taking the interaction between a transmitting device and a receiving device as an example.
[0209] As an example but not limitation, the transmitting device may be a device with communication capabilities in the WPAN, such as an FFD or an RFD; similarly, the receiving device may also be a device with communication capabilities in the WPAN, such as an FFD or an RFD.
[0210] It should be understood that the specific types and names of the transmitting device and the receiving device are not limited in this application, and any communication device that can transmit and receive UWB signals and NB signals can be used.
[0211] FIG6 is a schematic flowchart of a method for transmitting signaling provided in an embodiment of the present application, comprising the following steps:
[0212] S610: The transmitting device transmits a first UWB signal to the receiving device, or in other words, the receiving device receives the first UWB signal from the transmitting device.
[0213] Specifically, during the control phase of a first round, the transmitting device sends a first UWB signal to the receiving device. This first round can be any measurement round in the measurement process, and the control phase is used to complete the initial configuration of the measurement round. The measurement includes ranging or sensing measurement processes based on the UWB signal. For example, the first round can be any ranging round; or, for another example, the first round can be any sensing round.
[0214] For example, a receiving device receives a first UWB signal from a transmitting device during a ranging control phase. The transmitting device requires at least one ranging time slot to transmit the first UWB signal. In this embodiment, the ranging control phase may include more than one ranging time slot, wherein at least one ranging time slot of the more than one ranging time slot is used to transmit the first UWB signal.
[0215] In this embodiment, the first UWB signal is used to determine first indication information, where the first indication information is used to indicate a first number of segmented signals of the second UWB signal.
[0216] Optionally, the segmented signals included in the second UWB signal are identical. For example, the segmented signals included in the second UWB signal are preambles with identical configurations, wherein the preambles with identical configurations include but are not limited to: the length of the preamble, the sequence used by the preamble, and the like.
[0217] For ease of distinction, the first UWB signal can be referred to as a UWB test signal, and the second UWB signal can be referred to as a UWB measurement signal. The second UWB signal includes a UWB ranging signal and / or a UWB sensing signal, and can be understood as a UWB signal transmitted during the first measurement phase (e.g., ranging phase, sensing phase, etc.) for measurement.
[0218] It should be noted that the specific function of the second UWB signal in the embodiment of the present application is not limited. It can be a UWB signal for ranging, a UWB signal for sensing, or a UWB signal for realizing other measurement functions. Examples are not given here one by one.
[0219] In addition, the first number of segmented signals of the second UWB signal can be understood as follows: the second UWB signal is split into multiple segmented signals during transmission (as shown in FIG. 2 ), each segmented signal having a duration of less than 1 millisecond, and then only one of the segmented signals is transmitted within each millisecond, wherein the number of the multiple segmented signals is recorded as the first number. Exemplarily, the segmented signals in the multiple segmented signals are identical, for example, the segmented signals in the multiple segmented signals can be preambles of the same configuration, wherein the preambles of the same configuration include, but are not limited to, the length of the preamble, the sequence used by the preamble, and the like.
[0220] Optionally, when the number of segmented signals of the second UWB signal expected by the transmitting device is different from the number of segmented signals of the second UWB signal expected by the receiving device, the transmitting device and the receiving device can negotiate to obtain a suitable number of segmented signals of the second UWB signal for transmission. The negotiation process will be described below in conjunction with specific steps and will not be repeated here.
[0221] As a possible implementation, the first indication information implicitly indicates the number of segmented signals. For example, the first indication information is a segmented signal number index, which is used to indicate the first number of segmented signals of the second UWB signal expected by the transmitting device. In another example, the first indication information is a FoM value corresponding to the first UWB signal, which is used to determine the first number of segmented signals of the second UWB signal expected by the transmitting device.
[0222] For example, the transmitting device and the receiving device obtain or locally store a second mapping relationship (e.g., the transmitting device and the receiving device negotiate and determine and store the second mapping relationship, or the second mapping relationship is predefined by a protocol), where the second mapping relationship is a mapping relationship between the number index of the segmented signals and the number of segmented signals. In other words, after receiving the aforementioned number index of the segmented signals, the transmitting device can determine the number of segmented signals based on the locally stored second mapping relationship.
[0223] For example, the second mapping relationship is shown in Table 3a below:
[0224] Table 3a: Mapping relationship between the number index of segment signals and the number of segment signals
[0225] Wherein, FNI represents the Fragment Number Index (FNI) of the segment signal.
[0226] For another example, the transmitting device and the receiving device obtain or locally store a third mapping relationship (e.g., the transmitting device and the receiving device negotiate and determine and store the third mapping relationship, or the third mapping relationship is predefined by a protocol), where the third mapping relationship is a mapping relationship between the FoM value and the number of segmented signals. In other words, after receiving the FoM value, the transmitting device can determine the number of segmented signals based on the locally stored third mapping relationship.
[0227] For example, the third mapping relationship is shown in Table 3b below:
[0228] Table 3b: Mapping between FoM values and the number of segmented signals
[0229] As another possible implementation, the first indication information indicates the number of segmented signals. For example, the value of the first indication information is the number of segmented signals.
[0230] For example, when the first indication information value is 1, it indicates that the number of segmented signals is 1; when the first indication information value is 2, it indicates that the number of segmented signals is 2... and so on. When the first indication information value is N, it indicates that the number of segmented signals is N, where N is a positive integer.
[0231] It should be understood that the above is merely an example of a possible form of the first indication information and does not constitute any limitation on the scope of protection of this application. Other indication information that can be used to indicate the number of segmented signals is within the scope of protection of this application. For example, the first indication information indicates the confidence level corresponding to the first UWB signal, and the confidence level corresponding to the first UWB signal is used to determine the first number of segmented signals of the second UWB signal expected by the transmitting device. For ease of description, the following description uses the first indication information as an index of the number of segmented signals as an example.
[0232] From the above, it can be seen that the first UWB signal is used to determine the first indication information. After receiving the first UWB signal, the receiving end device can determine the first indication information based on the first UWB signal. Optionally, the method flow shown in FIG6 further includes:
[0233] S620: The receiving device determines first indication information according to the first UWB signal.
[0234] Specifically, the receiving end device determines the first indication information according to the first UWB signal including the following steps:
[0235] Step 1: The receiving end device determines the confidence level corresponding to the first UWB signal according to the quality of the first UWB signal.
[0236] For example, when the quality of the first UWB signal is good, it is determined (or estimated) that the confidence corresponding to the first UWB signal is high, and optionally, the corresponding FoM value is large; or, when the quality of the first UWB signal is poor, it is estimated that the confidence corresponding to the first UWB signal is low, and optionally, the corresponding FoM value is small.
[0237] It should be understood that this embodiment does not limit how to determine the confidence level corresponding to the first UWB signal based on the quality of the first UWB signal. Reference may be made to the description of determining the confidence level corresponding to the model based on signal quality in the current related art, which will not be repeated here.
[0238] Furthermore, after determining the confidence level corresponding to the first UWB signal, step 2 is performed.
[0239] Step 2: The receiving device determines first indication information according to the confidence level corresponding to the first UWB signal.
[0240] For example, the confidence level and the number of segmented signals of the second UWB signal have a mapping relationship (referred to as a first mapping relationship for ease of distinction). The receiving device can determine the number of segmented signals of the second UWB signal based on the confidence level and the first mapping relationship, thereby determining the first indication information. The first mapping relationship is a mapping relationship between the confidence level and the number of segmented signals.
[0241] For example, the first mapping relationship is shown in Table 4a and Table 4b below:
[0242] Table 4a: Example 1 of the mapping relationship between confidence and the number of segmented signals
[0243] Table 4b: Example 2 of the mapping relationship between confidence and the number of segmented signals
[0244] It should be noted that Tables 4a and 4b above illustrate possible forms of the first mapping relationship and do not limit the scope of protection of this application. The first mapping relationship may also have other forms that can be used to indicate the relationship between the confidence level and the number of segmented signals. For example, Tables 4a and 4b above may include two columns: the confidence level and the number of segmented signals, with the confidence index and FNI being optional. Examples are not provided here one by one.
[0245] From Table 4a and Table 4b above, it can be seen that the higher the confidence level corresponding to the first UWB signal, the higher the confidence level of the device in estimating the arrival time of the signal transmitted by the UWB system. Therefore, the number of UWB signal segment signals transmitted by the corresponding estimated UWB system is smaller.
[0246] Exemplarily, in order to enable the receiving device to obtain relevant configuration of the first UWB signal, optionally, the method flow shown in FIG6 further includes:
[0247] S611: The transmitting device sends first configuration information to the receiving device, or in other words, the receiving device receives the first configuration information from the transmitting device.
[0248] The first configuration information is used to indicate the configuration of the first UWB signal.
[0249] Exemplarily, the first configuration information may be sent via a narrowband signal, such as being carried in the first narrowband signal. Specifically, in this embodiment, to improve the accuracy of receiving the first UWB signal, the receiving device receives a 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 is used to indicate the configuration of the first UWB signal.
[0250] For example, when the transmitting device is a ranging initiating device and the receiving device is a ranging responding device, the poll signal sent by the initiating end to the responding end during the ranging control phase includes first configuration information, and the first configuration information is used to indicate the configuration of the first UWB signal. For example, the poll signal includes but is not limited to: information indicating the length of the preamble code of the first UWB signal, information indicating the sequence used for the preamble code of the first UWB signal, etc. As a possible implementation method, the above-mentioned first UWB signal is a UWB signal sent during the control phase of the first measurement round in the measurement process, and the above-mentioned first configuration information can be carried by a narrowband signal transmitted during the control phase (such as a poll signal, a response signal, or a newly added narrowband signal sent during the control phase of the first measurement round).
[0251] As another possible implementation, if the above-mentioned first UWB signal is a UWB signal sent in the control phase of measurement round #1 after the first measurement round in the measurement process, then the above-mentioned first configuration information may not be sent. For example, the relevant configuration of the first UWB signal may follow the configuration of the UWB signal sent in the previous measurement round; or, the first configuration information may be carried in the poll signal sent in the control phase of measurement round #1; or, the first configuration information may also be sent before the poll signal sent in the control phase of measurement round #1.
[0252] Furthermore, after determining the first indication information, the receiving end device sends the first indication information to the transmitting end device so that the transmitting end device learns the first number of segmented signals of the second UWB signal determined by the receiving end device. The method flow shown in FIG6 further includes:
[0253] S630: The receiving device sends first indication information to the sending device, or in other words, the sending device receives the first indication information from the receiving device.
[0254] Exemplarily, the first indication information is transmitted via a narrowband signal. In other words, the first indication information can be a narrowband signal. As a possible implementation, in this embodiment, the receiving device can carry the first indication information in a predefined first information element and send it to the transmitting device (e.g., the first information element is transmitted via a narrowband signal). The predefined first information element is an information element that the transmitting device can parse. The first information element also includes a first address size description field and / or a first address field, wherein the first address size description field is used to indicate the address type of the device receiving the first information element, and the first address field is used to indicate the address of the device receiving the first information element.
[0255] 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:
[0256] Table 5: FFNE IE
[0257] Among them, the Address Size Specifier field indicates the address type of the device receiving the FFNE IE. The address size description field can also be other names, as long as it can indicate the address type of the device receiving the first information element, and this application does not limit it. The address type may include one or more of the following: short address (i.e., address length is 2 bytes), long address (i.e., address length is 8 bytes). Optionally, the indication rules are consistent with the previous generation UWB standard IEEE 802.15.4z, namely:
[0258] - 00: indicates no address, that is, 0 byte (Octet);
[0259] - 01: Reserved;
[0260] - 10: Indicates a short address, which is 2 bytes (Octet), corresponding to 16 bits;
[0261] - 11: Indicates a long address, which is 8 bytes (Octet), corresponding to 64 bits.
[0262] When the Address Size Specifier field value of the FFNE IE is 00, the Address field is 0, meaning it contains no address information. This can be understood as the receiving device broadcasting the FFNE IE. In other words, after generating the first information element, the receiving device can broadcast the first information element.
[0263] As another possible implementation manner, the receiving device may directly send the first indication information to the transmitting device without carrying it in the above-mentioned first information element.
[0264] For example, the receiving device sends the first indication information to the transmitting device according to the source address of the received first UWB signal.
[0265] For example, the newly added FFNE IE can be recognized and processed by devices that need to perform ranging or sensing functions. As a possible implementation method, the corresponding identification and processing method of the newly added FFNE IE is similar to the identification and processing method of nested IEs (e.g., RDM IE) specified in the existing protocol 802.15.4z. Reference can be made to the identification and processing method of nested IEs in the existing protocol 802.15.4z.
[0266] For example, the upper protocol layer of the sending device configures the FFNE IE and transmits it to the MAC layer of the sending device.
[0267] For another example, the MAC layer of the receiving device transmits the received FFNE IE to the upper layer protocol of the receiving device, and the upper layer of the protocol identifies and processes the FFNE IE.
[0268] As a possible implementation method, the newly added FFNE IE can be transmitted through a narrowband frequency band.
[0269] As another possible implementation method, the newly added FFNE IE can also be transmitted through the UWB band.
[0270] For ease of understanding, the following describes the newly added FFNE IE in detail with reference to Table 6.
[0271] Table 6 below is an extension and continuation of Table 7-18 of the existing 802.15.4z protocol. For the sake of brevity, the existing definition of Table 7-18 in the protocol is not reflected in Table 6 below. Specifically, as can be seen from Table 6 below, the newly added FFNE IE can be added to the nested IE list defined in Table 7-18 of the existing 802.15.4z protocol as a new IE in the 802.15.4ab protocol or later versions. Specifically, a reserved Sub-ID value in the nested IE list defined in Table 7-18 of the existing 802.15.4z protocol can be used to indicate the newly added FFNE IE.
[0272] Table 6:
[0273] In Table 6, T can be any one or more values between 0x5d and 0x7f. Table 6 can be an extension and continuation of the nested IE list defined in Table 7-18 of the existing 802.15.4z protocol. X in Table 6 indicates that the FFNE IE is a Data type IE.
[0274] Optionally, the message carrying the first indication information can be called a UWB block quantity feedback message, and the UWB block quantity feedback message is a narrowband signal. As a possible implementation method, the response message (Resp) of the receiving device to the Poll message and the UWB block quantity feedback message fed back by the receiving device to the transmitting device can be included in the same return message. That is to say, after receiving the Poll message, the receiving device does not need to respond immediately, but waits until the first number of segmented signals of the second UWB signal is received to determine the first number of segmented signals of the second UWB signal, and then responds to the Poll message and the UWB test block at the same time through one message. This is suitable for scenarios where a fast two-way narrowband handshake connection is not required between the transmitting device and the receiving device.
[0275] Exemplarily, in a certain ranging time slot after the transmitting device and the receiving device complete the polling initiation (Poll) and response (Resp) respectively, the transmitting device sends a UWB block (such as the first UWB signal mentioned above) for testing (training) purposes to the receiving device. That is, the Resp message of the receiving device and the UWB block quantity feedback message fed back by the receiving device to the initiator are two different messages. That is to say, after receiving the Poll message, the receiving device can respond to the Poll message, and after receiving the first UWB signal to determine the first number of segmented signals of the second UWB signal, send the first indication information. This is suitable for scenarios where a fast two-way handshake connection needs to be carried out between the initiator and the responder.
[0276] It should be understood that the above is only an example of how the receiving device sends the first indication information to the sending device, and does not constitute any limitation on the scope of protection of this application. In this embodiment, there is no limitation on how the receiving device sends the first indication information to the sending end, and it is sufficient to be able to send the first indication information to the sending device.
[0277] Optionally, after receiving the first indication information, the transmitting device can learn the first number of segmented signals of the second UWB signal expected by the receiving device. The transmitting device may also notify the receiving device of the second number of segmented signals of the second UWB signal expected by the transmitting device through the second indication information, or the transmitting device may also notify the receiving device of the fourth number of segmented signals of the second UWB signal expected by the transmitting device through the second indication information.
[0278] In this embodiment, the transmitting end device determines the number of segment signals of the second UWB signal expected by the transmitting end device in the following two ways:
[0279] Method 1: The transmitting end device determines the first number of segmented signals of the second UWB signal indicated by the received first indication information.
[0280] In the first embodiment, the method flow shown in FIG6 further includes:
[0281] S621: The transmitting end device determines a second number of segmented signals of the second UWB signal according to a first number of segmented signals of the second UWB signal.
[0282] As a possible implementation, the second number is the same as the first number. The transmitting device agrees to transmit the second UWB signal based on the first number, and in the first round of measurement, the transmitting device uses the first number to perform the UWB measurement process.
[0283] In this implementation mode, the transmitting device may notify the receiving device through the second indication information that the UWB measurement process can be carried out based on the first quantity; or, the transmitting device may not notify the receiving device; or, the transmitting device may notify the receiving device through the confirmation information (ACK) that the UWB measurement process can be carried out based on the first quantity.
[0284] As another possible implementation, the second number is different from the first number. Exemplarily, the reference factors that affect the sending end device in determining the second number include but are not limited to:
[0285] a) When there are multiple receiving end devices, each receiving end device feeds back a first number. For example, when the first numbers fed back by the multiple receiving end devices are different, the transmitting end device uses the largest first number among them as the second number.
[0286] Exemplarily, when there are multiple transmitting devices, the method for each transmitting device to determine the second number of segmented signals of the second UWB signal can refer to the above-mentioned situation of one transmitting device to multiple receiving devices, that is, the situation of multiple transmitting devices to multiple receiving devices can be understood as a multiple-to-many situation, which will not be repeated here.
[0287] b) Confidence history information of the UWB signal from multiple previous measurement rounds.
[0288] Method 2: When the noise levels of the UWB receivers of the transmitting device and the receiving device are significantly different, it is necessary to consider the UWB reception signal qualities of the UWB receivers of the transmitting device and the receiving device together to determine the final number of UWB block signals.
[0289] In the second approach, the method flow shown in FIG6 further includes:
[0290] S622: The receiving device sends a fifth UWB signal to the transmitting device, or in other words, the transmitting device receives the fifth UWB signal from the receiving device.
[0291] Similar to the function of the first UWB signal sent by the transmitting device to the receiving device in S610 above, the fifth UWB signal is used by the transmitting device to estimate the number of segmented signals of the second UWB signal transmitted in the measurement phase (such as the ranging phase, the perception phase, etc.) for implementing the measurement.
[0292] Exemplarily, the fifth UWB signal may also be referred to as a UWB test signal.
[0293] As a possible implementation manner, the first indication information fed back by the receiving device to the transmitting device and the fifth UWB signal initiated by the receiving device to the transmitting device are not limited in the order of sending time slots.
[0294] For example, the receiving device may first send the fifth UWB signal to the transmitting device, and then send the first indication information to the transmitting device. This is suitable for scenarios where the receiving device needs more time to process the first UWB signal from the transmitting device.
[0295] For another example, the receiving device may first send the first indication information to the transmitting device, and then send the fifth UWB signal to the transmitting device.
[0296] For example, after the receiving device sends the fifth UWB signal, it sends a response message (Resp) back to the transmitting device. This Resp message includes not only a response to the Poll, but also the first indication information to be fed back to the transmitting device. This can be understood as a combination of the Resp message and the UWB block quantity feedback message sent by the receiving device to the initiator.
[0297] Optionally, in mode 2, since UWB test signals need to be exchanged between the transmitting device and the receiving device, the above-mentioned poll signal can also be used to schedule the sending order of UWB test signals and narrowband signals of the transmitting device and the receiving device in the ranging control phase.
[0298] For example, the poll signal is used to indicate the time slots occupied by transmitting the first UWB signal, the first indication information, the fifth UWB signal, and the second indication information described below.
[0299] S623: The transmitting device determines a fourth number of segmented signals of the second UWB signal according to the first indication information and / or the fifth UWB signal.
[0300] Illustratively, in the second method, the transmitting device can determine the number of segmented signals of the second UWB signal transmitted in the measurement phase based on the narrowband signal (e.g., the first indication information) responded by the receiving device and / or the received wideband signal (e.g., the fifth UWB signal).
[0301] For example, the transmitting end device determines the number of segmented signals of the second UWB signal according to the received first indication information, which is similar to the above-mentioned step S621 and will not be repeated here.
[0302] For another example, the transmitting device determines the number of segmented signals of the second UWB signal transmitted during the measurement phase based on the received wideband signal (e.g., the fifth UWB signal). For example, the fifth UWB signal is used to determine a fifth number of segmented signals of the second UWB signal, and the transmitting device determines that the number of segmented signals of the second UWB signal is greater than or equal to the fifth number.
[0303] For another example, the transmitting end device determines the number of segmented signals of the second UWB signal transmitted in the measurement phase according to the received first indication information and the broadband signal (eg, the fifth UWB signal).
[0304] As a possible implementation, the fifth UWB signal is used to determine the fifth number of segmented signals of the second UWB signal. Specifically, under Method 2, the transmitting device may combine the first number of segmented signals of the second UWB signal indicated by the first indication information and the fifth number of segmented signals of the second UWB signal determined by the transmitting device based on the fifth UWB signal to ultimately determine the fourth number of segmented signals of the second UWB signal transmitted during the measurement phase (e.g., the ranging phase, the sensing phase, etc.) for implementing measurement.
[0305] Exemplarily, the transmitting end device uses the larger value of the first number of segmented signals of the second UWB signal and the fifth number of segmented signals of the second UWB signal as the fourth number of segmented signals of the second UWB signal; or, the transmitting end device uses the average of the first number of segmented signals of the second UWB signal and the fifth number of segmented signals of the second UWB signal as the fourth number of segmented signals of the second UWB signal. It should be understood that this embodiment does not limit how the transmitting end device determines the fourth number of segmented signals of the second UWB signal based on the first number of segmented signals of the second UWB signal and the fifth number of segmented signals of the second UWB signal. The transmitting end device only needs to take into account the received first indication information and / or the fifth UWB signal in the process of determining the fourth number of segmented signals of the second UWB signal. The transmitting end device can notify the receiving end device of the number of segmented signals of the second UWB signal expected by the transmitting end device through the second indication information. The method flow shown in Figure 6 also includes:
[0306] S631: The transmitting device sends second indication information to the receiving device, or in other words, the receiving device receives the second indication information from the transmitting device.
[0307] Specifically, the second indication information is used to indicate the number of segmented signals of the second UWB signal transmitted in the first round of measurement phase.
[0308] Corresponding to the above-mentioned method 1, the second indication information is used to indicate the second number of segmented signals of the second UWB signal; corresponding to the above-mentioned method 2, the second indication information is used to indicate the fourth number of segmented signals of the second UWB signal.
[0309] Exemplarily, the second indication information is transmitted via a narrowband. In other words, the second indication information may be a narrowband signal.
[0310] Exemplarily, the second indication information is carried in a notification message, and the notification message is used to schedule and indicate the order of sending segmented signals of the second UWB signal.
[0311] In addition, it should be noted that the message name is not limited in the embodiments of the present application. The above-mentioned message carrying the second indication information can be called a notification message or have other names.
[0312] Optionally, the notification message may be included in a Ranging Control Message (RCM).
[0313] As a possible implementation, this RCM continues to use the information elements defined in the previous-generation IEEE 802.15.4z standard. This RCM is used for basic configuration and scheduling instructions for ranging measurements, including but not limited to: scheduling instructions for the transmission order of ranging participating devices, configuration of ranging round parameters, configuration of ranging block structure parameters, and configuration of the UWB channel and preamble used for ranging. In this implementation, by reusing some information elements in the existing RCM, scheduling instructions are implemented to determine the transmission order of segmented UWB signals, thereby improving the solution's backward compatibility.
[0314] As another possible implementation, the RCM may be a newly defined message including one or more information elements, used to perform basic configuration and scheduling instructions for the UWB signal in the measurement phase.
[0315] In this embodiment, there is no limitation on RCM. Any message that can be used to perform basic configuration and scheduling instructions for the segmented signals of the UWB signal during the measurement phase is within the scope of protection of this application. For example, the RCM involved in this embodiment can also be a message that includes one or more information elements specified in the existing protocol and a newly added information element.
[0316] Similar to the first indication information mentioned above, as a possible implementation method, in this embodiment, the sending device can carry the second indication information in a predefined second information element and send it to the receiving device, wherein the second information element also includes a second address size description field and a second address field, wherein the second address size description field is used to indicate the address type of the device receiving the second information element, and the second address field is used to indicate the address of the device receiving the second information element.
[0317] The format of the second information element is similar to the format of the first information element described above, and will not be repeated here.
[0318] For example, the parameter configurations of the first UWB signal (and / or the fifth UWB signal) and the second UWB signal may be different. For example, parameters such as the preamble type and length may be different. The initiator may update the configuration of the preamble of the second UWB signal (and / or the fifth UWB signal), including but not limited to: the preamble length, the sequence used for the preamble, etc. The update process may be carried by the narrowband signal NB. Optionally, the method flow shown in FIG6 further includes:
[0319] S632: The transmitting device sends the second configuration information to the receiving device, or in other words, the receiving device receives the second configuration information from the transmitting device.
[0320] The second configuration information is used to indicate the configuration of the second UWB signal (and / or the fifth UWB signal). Exemplarily, the second configuration information may be sent via a narrowband signal, such as being carried in the second narrowband signal.
[0321] As a possible implementation method, the above-mentioned second narrowband signal and the second indication information are a narrowband signal. It can be understood that when the second narrowband signal carrying the second configuration information and the narrowband signal carrying the second indication information (such as the UWB block quantity feedback message) are a narrowband signal, the signaling transmission time can be saved and the effectiveness can be guaranteed. In the process shown in Figure 6, the receiving end device can be the initiating end device of the measurement or the responding end device of the measurement. The following is a description of the process of the method for transmitting signaling provided by this application when the receiving end device plays different roles in the ranging process with reference to specific examples.
[0322] Example 1: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the controlling device in the ranging process. The controlling device can be understood as the device that determines the relevant parameters in the ranging process.
[0323] FIG7( a ) is a schematic flow chart corresponding to Example 1, which includes the following steps:
[0324] Step 1: The initiating device sends a polling signal to the responding device.
[0325] Specifically, the polling signal includes but is not limited to: first ranging round related parameter configuration, UWB signal preamble related parameter configuration (such as preamble length, preamble sequence, etc.), UWB packet type (SP0~SP3), device role and time slot scheduling allocation, etc.
[0326] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0327] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0328] Step 3: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.
[0329] For the description related to the first UWB signal, reference may be made to the description of the first UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0330] Step 4: The responding device sends first indication information to the initiating device.
[0331] For the description related to the first indication information, reference may be made to the description of the first indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0332] Exemplarily, the first indication information may be sent in combination with a response signal for responding to the above-mentioned polling signal. This situation is not shown in FIG7 (a).
[0333] Step 5: The initiating device sends second indication information to the responding device.
[0334] For the description related to the second indication information, reference may be made to the description of the second indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0335] Step 6: The initiating device sends a second narrowband signal to the responding device.
[0336] For the description related to the second narrowband signal, reference may be made to the description of the second narrowband signal in the embodiment shown in FIG6 , which will not be repeated here.
[0337] After steps 1 to 6, the initiating device and the responding device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured for the second narrowband signal to perform subsequent processes of UWB ranging.
[0338] For example, the second indication information indicates that the number of segment signals of the UWB ranging signal is 4.
[0339] Example 2: The sending device is the responding device of ranging, the receiving device is the initiating device of ranging, and the sending device is the controlling device in the ranging process.
[0340] FIG7( b ) is a schematic flow chart corresponding to Example 2, which includes the following steps:
[0341] Step 1: The initiating device sends a polling signal to the responding device.
[0342] Specifically, the polling signal includes but is not limited to: first ranging round related parameter configuration, UWB signal preamble related parameter configuration (such as preamble length, preamble sequence, etc.), UWB packet type (SP0~SP3), device role and time slot scheduling allocation, etc.
[0343] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0344] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0345] Step 3: In the ranging control phase, the responding device sends a first UWB signal to the initiating device.
[0346] Step 4: The initiating device sends first indication information to the responding device.
[0347] Step 5: The initiating device sends a second narrowband signal to the responding device.
[0348] For the description related to the second narrowband signal, reference may be made to the description of the second narrowband signal in the embodiment shown in FIG6 , which will not be repeated here.
[0349] After steps 1 to 5, the initiating device and the responding device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured for the second narrowband signal to perform subsequent processes of UWB ranging.
[0350] For example, the first indication information indicates that the number of segment signals of the UWB ranging signal is 4.
[0351] Example 3: The transmitting device is an initiating device of ranging, the receiving device is a responding device of ranging, and also includes a control device.
[0352] FIG7( c ) is a schematic flow chart corresponding to Example 3, which includes the following steps:
[0353] Step 1: The initiating device (or controlling device) sends a polling signal to the responding device.
[0354] Specifically, the polling signal includes but is not limited to: first ranging round related parameter configuration, UWB signal preamble related parameter configuration (such as preamble length, preamble sequence, etc.), UWB packet type (SP0~SP3), device role and time slot scheduling allocation, etc.
[0355] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0356] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0357] Step 3: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.
[0358] Step 4: The responding device sends the first indication information to the controlling device.
[0359] For the description related to the first indication information, reference may be made to the description of the first indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0360] Exemplarily, the first indication information may be sent in combination with a response signal for responding to the above-mentioned polling signal. This situation is not shown in (c) of FIG7 .
[0361] Step 5: The control device sends instruction information #1 to the initiating device and the responding device respectively.
[0362] The control device determines whether to transmit the second UWB signal based on the first number of blocks. When the control device determines to transmit the second UWB signal based on the first number of blocks, the control device sends indication information #1 to the receiving device and the transmitting device. For example, the control device broadcasts cell #1, which includes indication information #1; or sends indication cells #2 and #3 to the receiving device and the transmitting device, respectively, which include indication information #1.
[0363] Step 6: The initiating device (or the controlling device) sends a second narrowband signal to the responding device.
[0364] After steps 1 to 6, the initiating device and the responding device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured for the second narrowband signal to perform subsequent processes of UWB ranging.
[0365] For example, the above-mentioned indication information #1 indicates that the number of segment signals of the UWB ranging signal is 4.
[0366] Specifically, (a) to (c) in Figure 7 are directed to the transmitting device determining the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving device. It can be seen from the process shown in Figure 6 that the transmitting device can also determine the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving device and / or the UWB test signal sent by the receiving end. The following takes the transmitting device as the initiating device of ranging, the receiving device as the responding device of ranging, and the initiating device as the control device in the ranging process as an example to illustrate the specific process of the embodiment described in Figure 6 when the transmitting device determines the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving device and / or the UWB test signal sent by the receiving end.
[0367] As a possible implementation method, the following steps are included:
[0368] Step 1a: The initiating device sends a polling signal to the responding device.
[0369] Exemplarily, the polling signal is used to indicate the order in which the initiating device and the responding device transmit the UWB test signal and the narrowband signal in the ranging control phase.
[0370] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0371] Step 2a: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.
[0372] For the description related to the first UWB signal, reference may be made to the description of the first UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0373] Step 3a: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0374] Exemplarily, the response message (Resp) of the responding end device to the Poll message and the UWB block quantity feedback message fed back by the responding end device to the initiating end device are included in the same return message.
[0375] Step 4a: The responding device sends a fifth UWB signal to the initiating device.
[0376] For the description related to the fifth UWB signal, reference may be made to the description of the fifth UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0377] Step 5a: The initiating device sends second indication information to the responding device.
[0378] For the description related to the second indication information, reference may be made to the description of the second indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0379] Step 6a: The initiating device sends a second narrowband signal to the responding device.
[0380] For the description related to the second narrowband signal, reference may be made to the description of the second narrowband signal in the embodiment shown in FIG6 , which will not be repeated here.
[0381] After step 1a to step 6a, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal and the parameters configured for the second narrowband signal to perform subsequent processes of UWB ranging.
[0382] The above steps 1a to 6a are shown in (d) of FIG. 7 . It should be noted that the order of the above steps 1a to 6a is not limited.
[0383] Another possible implementation method includes the following steps:
[0384] Step 1b: The initiating device sends a polling signal to the responding device.
[0385] Exemplarily, the polling signal is used to indicate the order in which the initiating device and the responding device transmit the UWB test signal and the narrowband signal in the ranging control phase.
[0386] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0387] Step 2b: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0388] Step 3b: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.
[0389] For the description related to the first UWB signal, reference may be made to the description of the first UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0390] Step 4b: The responding device sends first indication information to the initiating device.
[0391] In this implementation, the Resp message sent by the responding device and the UWB block quantity feedback message fed back by the responding device to the initiating device are not combined.
[0392] Step 5b: The responding device sends a fifth UWB signal to the initiating device.
[0393] For the description related to the fifth UWB signal, reference may be made to the description of the fifth UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0394] Step 6b: The initiating device sends second indication information to the responding device.
[0395] For the description related to the second indication information, reference may be made to the description of the second indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0396] Step 7b: The initiating device sends a second narrowband signal to the responding device.
[0397] For the description related to the second narrowband signal, reference may be made to the description of the second narrowband signal in the embodiment shown in FIG6 , which will not be repeated here.
[0398] The above steps 1b to 6b are shown in (e) of FIG. 7 .
[0399] Another possible implementation method includes the following steps:
[0400] Step 1c: The initiating device sends a polling signal to the responding device.
[0401] Exemplarily, the polling signal is used to indicate the order in which the initiating device and the responding device transmit the UWB test signal and the narrowband signal in the ranging control phase.
[0402] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0403] Step 2c: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0404] Step 3c: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.
[0405] For the description related to the first UWB signal, reference may be made to the description of the first UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0406] Step 4c: The responding device sends a fifth UWB signal to the initiating device.
[0407] For the description related to the fifth UWB signal, reference may be made to the description of the fifth UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0408] Step 5c: The responding device sends first indication information to the initiating device.
[0409] In this implementation, the Resp message sent by the responding device is not combined with the UWB block number feedback message sent back to the initiating device. The responding device sends the Resp message first, followed by the UWB block number feedback message. This is suitable for scenarios where the responding device needs more time to process the UWB test signal from the initiating device.
[0410] Step 6c: The initiating device sends second indication information to the responding device.
[0411] For the description related to the second indication information, reference may be made to the description of the second indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0412] Step 7c: The initiating device sends a second narrowband signal to the responding device.
[0413] For the description related to the second narrowband signal, reference may be made to the description of the second narrowband signal in the embodiment shown in FIG6 , which will not be repeated here.
[0414] The above steps 1c to 6c are shown in (f) of FIG. 7 .
[0415] Another possible implementation method includes the following steps:
[0416] Step 1d: The initiating device sends a polling signal to the responding device.
[0417] Exemplarily, the polling signal is used to indicate the order in which the initiating device and the responding device transmit the UWB test signal and the narrowband signal in the ranging control phase.
[0418] Exemplarily, the polling signal may be understood as the first narrowband signal involved in the embodiment shown in FIG. 6 .
[0419] Step 2d: In the ranging control phase, the initiating device sends a first UWB signal to the responding device.
[0420] For the description related to the first UWB signal, reference may be made to the description of the first UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0421] Step 3d: The responding device sends a fifth UWB signal to the initiating device.
[0422] Step 4d: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0423] Exemplarily, the response message (Resp) of the responding end device to the Poll message and the UWB block quantity feedback message fed back by the responding end device to the initiating end device are included in the same return message.
[0424] For the description related to the fifth UWB signal, reference may be made to the description of the fifth UWB signal in the embodiment shown in FIG6 , which will not be repeated here.
[0425] Step 5d: The initiating device sends second indication information to the responding device.
[0426] For the description related to the second indication information, reference may be made to the description of the second indication information in the embodiment shown in FIG6 , which will not be repeated here.
[0427] Step 6d: The initiating device sends a second narrowband signal to the responding device.
[0428] For the description related to the second narrowband signal, reference may be made to the description of the second narrowband signal in the embodiment shown in FIG6 , which will not be repeated here.
[0429] The above steps 1d to 6d are shown in (g) of FIG. 7 .
[0430] Similarly, for the case where the above-mentioned transmitting device determines the number of segmented signals of the second UWB signal based on the first indication information sent by the receiving device and / or the UWB test signal sent by the receiving end, wherein the transmitting device is the responding device of ranging, the receiving device is the initiating device of ranging, and the transmitting device is the control device in the ranging process, the case is similar to the above-mentioned transmitting device being the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the control device in the ranging process. For example, the device that sends the first indication information and / or the first UWB signal in (d) to (g) of Figure 7 is replaced by the initiating device, and the device that sends the fifth UWB signal is replaced by the responding device, and in this case the Resp message will not be sent in combination with the first indication information.
[0431] In addition, (d) to (g) in Figure 7 show the case where the initiating device is a controlling device. If the responding device is a controlling device, the initiating device needs to return to the responding device the fifth number of segmented signals of the UWB signal determined based on the fifth UWB signal, and the responding device finally determines the number of segmented signals of the UWB signal based on the received information indicating the fifth number and the first UWB signal, and notifies the initiating device through a notification message.
[0432] The above embodiments are all described using a one-to-one scenario as an example, i.e., one initiating device and one responding device. It should be noted that the signaling transmission method shown in FIG6 can also be extended to a one-to-many or many-to-many scenario, i.e., one initiating device and multiple responding devices, or multiple initiating devices and multiple responding devices.
[0433] For example, the one-to-many situation is shown in (h) in FIG. 7 .
[0434] The Poll message in the ranging control phase can be used to schedule and instruct the initiator device and multiple responders on the order of sending multiple UWB test signals and multiple narrowband signals in the ranging control phase.
[0435] For example, the initiator device is instructed to send the time slots occupied by the UWB test signal and the narrowband signal, and the multiple responder devices are instructed to send the time slots occupied by multiple UWB test signals and multiple narrowband signals.
[0436] As a possible implementation manner, the initiating end device may send a notification message in the ranging control phase to notify the number of segmented signals of the second UWB signal in the measurement phase.
[0437] Optionally, the notification message in the ranging control phase may also be used to schedule and indicate a sending order of segmented signals of multiple second UWB signals of the initiating end device and multiple responding end devices in a subsequent measurement phase.
[0438] For example, the announcement message is used to indicate the time slots occupied by the initiating end device and multiple responding end devices in sending segmented signals.
[0439] The following example illustrates how the initiating device determines the number of segmented signals of the second UWB signal transmitted during the measurement phase in a one-to-many situation.
[0440] Assume that there are N responding end devices, and the number of segmented signals generated by each responding end device is estimated to be F1, F2…F N .
[0441] For the case where the transmitting end device determines the number of segment signals of the second UWB signal according to the number of segment signals fed back by the responding end device:
[0442] The sending device can F1, F2...F N The maximum value among is used as the number of segmented signals of the second UWB signal transmitted in the measurement phase.
[0443] Regarding the case where the transmitting end device determines the number of segment signals of the second UWB signal based on the number of segment signals fed back by the responding end device and the number of segment signals estimated by itself:
[0444] Corresponding to the UWB test signals (eg, multiple fifth UWB signals) respectively sent by multiple responding end devices, the transmitting end device accordingly sets the number of multiple segmented signals, which is recorded as F N+1 ,F N+2 …F 2N A simple method for determining the number of segment signals of the final second UWB signal is, F1, F2...FN and F N+1 ,F N+2 …F 2N The maximum number of segmented signals in the second UWB signal is used as the number of segmented signals of the second UWB signal, that is: The number of segmented signals of the second UWB signal = max(F1, F2…F 2N )
[0445] In the many-to-many case, the method for each initiating end device to determine the number of segmented signals of the second UWB signal can refer to the above one-to-many case, that is, the many-to-many case can be understood as the many-to-many case, which will not be repeated here.
[0446] From the above, it can be seen that in the embodiment shown in Figure 6, in the ranging control stage, the number of UWB blocks can be estimated based on the quality of the UWB test signal. Compared with the existing solution based on the estimation of the narrowband NB signal, it will be more accurate, reduce the probability of incorrectly configuring the number of UWB blocks, and avoid or reduce the probability of reduced system efficiency.
[0447] In addition, the embodiment shown in Figure 6 can avoid or reduce the probability of inappropriate configuration of the receiver on period of the receiving / transmitting device, thereby avoiding or reducing the probability that the receiving / transmitting device cannot effectively sleep and consumes power too quickly, thereby avoiding or reducing the probability of a reduction in the working time of the receiving / transmitting device.
[0448] In addition, this application also provides another method for transmitting signaling, which adjusts the inappropriate number of UWB blocks to the appropriate number of UWB blocks in a timely manner according to the actual measurement effect of the current ranging wheel, thereby avoiding wasting a lot of time in the subsequent continuous ranging process, thereby improving system efficiency. The method for transmitting signaling will be described in detail below with reference to the accompanying drawings.
[0449] Unless otherwise specified, the specific description of certain technical features in one embodiment can also be applied to the explanation of corresponding technical features mentioned in other embodiments. For example, the specific description of segmented signals of a UWB signal in the embodiment shown in FIG6 can be applied to the embodiment shown in FIG8 , and the concept of segmented signals does not need to be elaborated in the embodiment shown in FIG8 . For another example, the specific description of determining the number of segmented signals of a UWB signal based on the confidence level of the UWB signal in the embodiment shown in FIG6 can also be applied to the embodiment shown in FIG8 . Examples will not be given one by one here.
[0450] FIG8 is a schematic flow chart of another method for transmitting signaling provided by the present application, comprising the following steps:
[0451] S810: The transmitting end device determines third indication information according to at least one segment signal of a fourth UWB signal.
[0452] The third indication information is used to indicate a third number of segmented signals of the third UWB signal. The fourth UWB signal is a UWB signal for measurement (e.g., sensing or ranging) transmitted in the current measurement round. The UWB signal is split into multiple segmented signals for transmission during transmission, and the transmitting device is a device that receives the multiple segmented signals.
[0453] In this embodiment, the transmitting end device can determine the actual measurement effect of the current measurement round based on the quality of the received segmented signal, and determine that the number of segmented signals of the current UWB signal is no longer appropriate and needs to be changed (or updated).
[0454] As a possible implementation manner, the transmitting end device may determine the third indication information according to any segment signal of the received fourth UWB signal.
[0455] For example, the transmitting device determines the third indication information based on the quality of any one of the multiple segmented signals received. Specifically, the method of determining the number of segmented signals of the UWB signal to be transmitted based on the quality of the UWB signal can refer to the description of "determining the first indication information based on the first UWB signal" in the embodiment shown in Figure 6, which will not be repeated here.
[0456] As another possible implementation manner, the transmitting end device may determine the third indication information according to multiple segment signals of the received fourth UWB signal.
[0457] For example, the transmitting end device determines the third indication information according to the average confidence value of the multiple received segmented signals.
[0458] It should be understood that the above is merely an example of how to determine the third indication information based on the segmented signal, and does not constitute any limitation on the scope of protection of this application.
[0459] S820: The transmitting device sends third indication information to the control device, or the control device receives the third indication information from the transmitting device.
[0460] Exemplarily, the third indication information is transmitted via a narrowband. In other words, the third indication information may be a narrowband signal.
[0461] Similar to the first indication information mentioned above, as a possible implementation method, in this embodiment, the sending device can carry the third indication information in a predefined third information element and send it to the control device, wherein the third information element also includes a third address size description field and a third address field, wherein the third address size description field is used to indicate the address type of the device receiving the third information element, and the third address field is used to indicate the address of the device receiving the third information element.
[0462] The format of the third information element is similar to the format of the first information element described above, and will not be repeated here.
[0463] Optionally, the transmitting device may send a second message to the control device to instruct the control device to change the number of segmented signals of the third UWB signal. Optionally, the method flow shown in FIG8 further includes:
[0464] S830: The transmitting device sends second information to the control device, or the control device receives the second information from the transmitting device.
[0465] The second information is used to indicate a change in the number of segmented signals of the third UWB signal. Exemplarily, the second information is triggered by a ranging change request message (Ranging Change Request Information Element, RCR IE).
[0466] As a possible implementation, the RCR IE uses the information elements defined in the previous generation IEEE 802.15.4z standard. This RCR IE is used to trigger ranging change requests, including but not limited to changes in ranging round parameter configuration and ranging block structure. In this implementation, by reusing existing information elements, the number of segments indicating UWB signals can be changed, improving the solution's backward compatibility.
[0467] As another possible implementation, the RCR IE may be a newly defined information element, used to indicate a change in the number of segmented signals of the UWB signal.
[0468] In this embodiment, no limitation is imposed on the RCR IE, and any information element that can be used to indicate a change in the number of segmented signals of a UWB signal is within the protection scope of this application.
[0469] Exemplarily, the second information is transmitted via a narrowband, and the second information may be a narrowband signal.
[0470] Specifically, after receiving the third indication information, the control device may notify the transmitting device through the first information whether it agrees to change the number of segments of the third UWB signal. The method shown in FIG8 further includes:
[0471] S840: The control device sends first information to the sending end device, or the sending end device receives the first information from the control device.
[0472] The first information is used to indicate whether to agree to change the number of segments of the third UWB signal.
[0473] Exemplarily, the first information is transmitted via a narrowband, and the first information may be a narrowband signal.
[0474] As a possible implementation manner, the first information indicates agreement to update the number of segments of the third UWB signal.
[0475] For example, the first information is confirmation information (ACK).
[0476] Optionally, in this implementation mode, after the control device sends the confirmation information, it can also indicate the third number of segmented signals of the third UWB signal by sending a fourth indication information; or, it can also indicate the fourth number of segmented signals of the third UWB signal by sending a fourth indication information, and the fourth number is different from the third number.
[0477] For another example, the first information is the fourth indication information.
[0478] Specifically, in this implementation, the control device may send fourth indication information to both the transmitting device and the receiving device, so that the transmitting device and the receiving device can subsequently perform UWB signal transmission based on the changed number of segmented signals of the UWB signal. Optionally, the method flow shown in FIG8 further includes:
[0479] S850: The control device sends 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.
[0480] Exemplarily, the fourth indication information is transmitted via a narrowband, and the fourth indication information may be a narrowband signal.
[0481] Similar to the first indication information mentioned above, as a possible implementation method, in this embodiment, the sending device can carry the fourth indication information in a predefined fourth information element and send it to the control device, wherein the fourth information element also includes a fourth address size description field and / or a fourth address field, wherein the fourth address size description field is used to indicate the address type of the device receiving the fourth information element, and the fourth address field is used to indicate the address of the device receiving the fourth information element.
[0482] The format of the fourth information element is similar to the format of the first information element described above, and will not be repeated here.
[0483] For example, the control device broadcasts the fourth information element.
[0484] For another example, the control device sends a fourth information cell #1 to a transmitting device. The fourth address size specification field and / or the fourth address field in the fourth information cell #1 indicate that the device receiving the fourth information cell #1 is the transmitting device. The fourth information cell #1 includes fourth indication information. Furthermore, the control device sends a fourth information cell #2 to a receiving device. The fourth address size specification field and / or the fourth address field in the fourth information cell #2 indicate that the device receiving the fourth information cell #2 is the receiving device. The fourth information cell #2 includes fourth indication information.
[0485] As another possible implementation manner, the first information indicates the number of segment signals that do not agree to update the third UWB signal.
[0486] It should be understood that this embodiment mainly considers the case where the control device agrees to update the number of segment signals of the third UWB signal, and does not elaborate on the case where the control device disagrees to update the number of segment signals of the third UWB signal.
[0487] As a possible implementation, the transmitting device may send the first information and the third indication information to the control device during the first round of measurement reporting. In this implementation, the control device may send the fourth indication information to the transmitting device and the receiving device during the first round of measurement reporting; or
[0488] The control device may send fourth indication information to the transmitting device and the receiving device before the second round of measurement phase.
[0489] In this implementation, after receiving the fourth indication information, the transmitting device and the receiving device can transmit a third UWB signal based on the changed number of segmented signals in the second round of measurement. The second round is the measurement round after the first round. According to the actual measurement effect of the current ranging round, the number of inappropriate segmented signals can be adjusted to the number of appropriate segmented signals in a timely manner to avoid wasting a lot of time in the subsequent multiple consecutive ranging processes, thereby improving system efficiency. In addition, this implementation can avoid or reduce the probability of inappropriate configuration of the receiver on-time period of the receiving / transmitting device, thereby avoiding or reducing the probability that the receiving / transmitting device cannot effectively sleep and consumes power too quickly, thereby avoiding or reducing the probability of a reduction in the working time of the receiving / transmitting device. It should be noted that the above-mentioned second round is the measurement round after the first round, which can be understood as: the second round is carried out after the end of the first round.
[0490] The second round will be launched after the first round, including the following two situations:
[0491] Case 1: The second round and the first round are adjacent measuring rounds. Specifically, the second round can begin immediately after the first round ends. This can be understood as the end time of the first round being the start time of the second round, or the duration between the end time of the first round and the start time of the second round is less than a preset threshold and no other measuring rounds are included in this duration.
[0492] Case 2: The second round and the first round are not adjacent distance measuring rounds. Specifically, the second round does not start immediately after the first round ends. In other words, there can be a certain amount of time between the second and first rounds, for example, there are other distance measuring rounds between the second and first rounds. This can be understood as the time between the end of the first round and the start of the second round being greater than a preset threshold.
[0493] The size of the preset threshold is not limited in the embodiment of the present application. For example, in case 2, the end time of the first round and the start time of the second round may be separated by the duration of several rounds, wherein these separated rounds can be used for other ranging processes or left idle.
[0494] For example, in case 2, the interval between the end time of the first round and the start time of the second round being greater than the preset threshold includes: the second round and the first round are not within the same ranging block. For example, the first round is a ranging round within the current ranging block, while the second round is a ranging round within the next ranging block (e.g., a ranging block adjacent to the current ranging block). In this case, the interval between the second round and the first round is the duration of several rounds, where these interval rounds can be used for other ranging processes or left idle. For another example, the first round is a ranging round within the current ranging block, while the second round can be a ranging round within a subsequent ranging block (e.g., a ranging block separated from the current ranging block by at least one ranging block).
[0495] The distance measuring block mentioned above can be understood as the time length including one or more distance measuring wheels.
[0496] As another possible implementation, the transmitting device may send the first information and the third indication information to the control device at the first moment in the first round of measurement phase. In this implementation, the control device may send the fourth indication information to the transmitting device and the receiving device before the second round of measurement phase; or
[0497] The control device may send fourth indication information to the transmitting device and the receiving device at the second moment in the measurement phase of the first round.
[0498] The third UWB signal includes a UWB signal transmitted in the second round of measurement phase and / or a UWB signal transmitted after a second time in the first round of measurement phase, where the second time is later than the first time.
[0499] In this implementation, after receiving the fourth indication information, the transmitting device and the receiving device may transmit a third UWB signal based on the changed number of segmented signals during the second measurement round, the second round being the measurement round following the first round. Alternatively, after receiving the fourth indication information, the transmitting device and the receiving device may transmit a third UWB signal based on the changed number of segmented signals after the second moment in the first measurement round. Based on the actual measurement results of the current ranging round, the number of inappropriate segmented signals can be promptly adjusted to the appropriate number of segmented signals, thereby avoiding wasting time during the remaining time of the measurement phase of the current ranging round and during subsequent consecutive ranging rounds, thereby improving system efficiency. Furthermore, this implementation can avoid or reduce the probability of inappropriate receiver on-time configuration of the receiving / transmitting device, thereby avoiding or reducing the probability of the receiving / transmitting device failing to effectively sleep and consuming power excessively, and thereby avoiding or reducing the probability of a reduction in the operating time of the receiving / transmitting device. In the process shown in Figure 8, the receiving device can be the initiating device of the measurement or the responding device of the measurement; alternatively, the initiating device and the control device are the same device, and the responding device and the control device are the same device. The following describes, with specific examples, the process of the signaling transmission method provided in this application when the receiving device plays different roles in the ranging process.
[0500] Example 4: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and also includes a control device. The control device can be understood as a device that determines relevant parameters in the ranging process.
[0501] FIG9 is a schematic flow chart corresponding to Example 4, which includes the following steps:
[0502] Step 1: The initiating device sends a polling signal to the responding device.
[0503] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0504] Step 3: The initiating device and the responding device transmit UWB ranging signals to perform ranging.
[0505] For the sake of distinction, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this fourth example, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #2.
[0506] The initiating device determines third indication information according to the received segment signal of the fourth UWB signal #2.
[0507] Step 4: The initiating device sends the second information and the third indication information to the control device.
[0508] Step 4 includes two possibilities:
[0509] Possibility 1: The initiating device sends the second information and the third indication information in the current ranging phase, as shown in FIG9 (a).
[0510] Possibility 2: The initiating device sends the second information and the third indication information during the ranging reporting phase, as shown in FIG9( b ).
[0511] Step 5: The control device sends the first information to the initiating device.
[0512] Step 6: The control device sends fourth indication information to the initiating device and the responding device.
[0513] Specifically, after receiving the third indication information, the control device sends the fourth indication information to the initiating end device and the responding end device. The following possibilities are included:
[0514] When the initiating device sends the second information and the third indication information during the current ranging phase, the control device may send the fourth indication information to the initiating device and the responding device during the current ranging phase. Alternatively, the control device may also begin sending the fourth indication information to the initiating device and the responding device before the start of the ranging phase of the next ranging round (e.g., the ranging result reporting phase of the current ranging round or the control phase of the next ranging round). FIG9 (a) illustrates sending the fourth indication information to the initiating device and the responding device during the ranging result reporting phase of the current ranging round as an example. The next ranging round may be a ranging round adjacent to the current ranging round, or may be a ranging round separated from the current ranging round by at least one ranging round.
[0515] When the initiating device sends the second information and the third indication information during the ranging reporting phase of the current ranging round, the control device may send the fourth indication information to the initiating device and the responding device during the ranging reporting phase of the current ranging round; or, the control device may also start sending the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the control phase of the next ranging round). FIG9 (b) shows an example of sending the fourth indication information to the initiating device and the responding device during the ranging result reporting phase of the current ranging round.
[0516] After step 1 to step 6, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform subsequent processes of the UWB ranging.
[0517] For example, the fourth indication information indicates that the number of segment signals of the UWB ranging signal is 8. One possibility is that, after receiving the fourth indication information, the initiating device and the responding device directly use the changed number of segment signals to perform ranging in the period after the number of segment signals in the ranging phase of the current ranging round is changed. Another possibility is that, after receiving the fourth indication information, the initiating device and the responding device will use the changed number of segment signals to perform UWB ranging in the next UWB ranging round.
[0518] Example 5: The transmitting device is a responding device of ranging, the receiving device is an initiating device of ranging, and also includes a control device.
[0519] FIG10 is a schematic flow chart corresponding to Example 4, which includes the following steps:
[0520] Step 1: The initiating device sends a polling signal to the responding device.
[0521] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0522] Step 3: The initiating device and the responding device transmit UWB ranging signals to perform ranging.
[0523] For the sake of distinction, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this fifth example, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #1.
[0524] The responding end device determines third indication information according to the received segment signal of the fourth UWB signal #1.
[0525] Step 4: The responding device sends the second information and the third indication information to the control device.
[0526] Step 4 includes two possibilities:
[0527] Possibility 1: The responding end device sends the second information and the third indication information in the current ranging phase, as shown in FIG10(a).
[0528] Possibility 2: The responding end device sends the second information and the third indication information during the ranging reporting phase, as shown in FIG10( b ).
[0529] Step 5: The control device sends the first information to the responding device.
[0530] Step 6: The control device sends fourth indication information to the initiating device and the responding device.
[0531] Specifically, after receiving the third indication information, the control device sends the fourth indication information to the initiating end device and the responding end device. The following possibilities are included:
[0532] When the initiating device sends the second information and the third indication information in the current ranging phase, the control device may send the fourth indication information to the initiating device and the responding device in the current ranging phase; or, the control device may also start sending the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the ranging result reporting phase of the current ranging round or the control phase of the next ranging round). FIG10 (a) shows an example of sending the fourth indication information to the initiating device and the responding device in the ranging result reporting phase of the current ranging round.
[0533] When the initiating device sends the second information and the third indication information during the ranging reporting phase of the current ranging round, the control device may send the fourth indication information to the initiating device and the responding device during the ranging reporting phase of the current ranging round; or, the control device may also start sending the fourth indication information to the initiating device and the responding device before the ranging phase of the next ranging round starts (e.g., the control phase of the next ranging round). FIG10 (b) shows an example of sending the fourth indication information to the initiating device and the responding device during the ranging result reporting phase of the current ranging round.
[0534] After step 1 to step 6, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform subsequent processes of the UWB ranging.
[0535] Example 6: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the initiating device is the controlling device in the ranging process.
[0536] FIG11 is a schematic flow chart corresponding to Example 6, which includes the following steps:
[0537] Step 1: The initiating device sends a polling signal to the responding device.
[0538] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0539] Step 3: The initiating device and the responding device transmit UWB ranging signals to perform ranging.
[0540] For the sake of distinction, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this fourth example, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #2.
[0541] The initiating device determines third indication information according to the received segment signal of the fourth UWB signal #2.
[0542] Step 4: The initiating device sends third indication information to the responding device.
[0543] Step 4 includes two possibilities:
[0544] Possibility 1: The initiating device sends the third indication information in the current ranging phase, as shown in FIG11(a).
[0545] Possibility 2: The initiating device sends the third indication information during the ranging reporting phase, as shown in FIG11( b ).
[0546] After step 1 to step 4, the initiating end device and the responding end device may transmit the UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform subsequent processes of the UWB ranging.
[0547] For example, when the initiating device sends the third indication information in the current ranging phase, after receiving the third indication information, the responding device directly uses the changed number of segmented signals to carry out ranging in the time period after the number of segmented signals in the ranging phase of the current ranging round is changed; another possibility is that the initiating device and the responding device will use the changed number of segmented signals to carry out UWB ranging in the next UWB ranging round.
[0548] For another example, when the initiating device sends the third indication information in the ranging reporting phase, the initiating device and the responding device will use the changed number of segmented signals to perform UWB ranging in the next UWB ranging round.
[0549] Example 7: The transmitting device is the initiating device of ranging, the receiving device is the responding device of ranging, and the responding device is the controlling device in the ranging process.
[0550] FIG12 is a schematic flow chart corresponding to Example 7, which includes the following steps:
[0551] Step 1: The initiating device sends a polling signal to the responding device.
[0552] Step 2: The responding end device sends a response signal to the initiating end device in response to the above-mentioned polling signal.
[0553] Step 3: The initiating device and the responding device transmit UWB ranging signals to perform ranging.
[0554] For the sake of distinction, the UWB ranging signal sent by the initiating device to the responding device during the ranging phase is recorded as the fourth UWB signal #1, and the UWB ranging signal sent by the responding device to the initiating device is recorded as the fourth UWB signal #2. In the case of this fourth example, the fourth UWB signal in the embodiment shown in FIG. 8 is the fourth UWB signal #2.
[0555] The initiating device determines third indication information according to the received segment signal of the fourth UWB signal #2.
[0556] Step 4: The initiating device sends the second information and the third indication information to the responding device.
[0557] Step 4 includes two possibilities:
[0558] Possibility 1: The initiating device sends the second information and the third indication information in the current ranging phase, as shown in FIG12(a).
[0559] Possibility 2: The initiating device sends the second information and the third indication information during the ranging reporting phase, as shown in FIG12(b).
[0560] Step 5: The responding device sends fourth indication information to the initiating device.
[0561] Specifically, after receiving the third indication information, the responding end device sends the fourth indication information to the initiating end device. The following possibilities are included:
[0562] When the initiating device sends the second information and the third indication information in the current ranging phase, the responding device may send the fourth indication information to the initiating device in the current ranging phase; or, it may also start sending the fourth indication information to the initiating device before the ranging phase of the next ranging round begins (e.g., the ranging result reporting phase of the current ranging round or the control phase of the next ranging round). FIG12 (a) shows an example of sending the fourth indication information to the initiating device and the responding device in the ranging result reporting phase of the current ranging round.
[0563] When the initiating device sends the second information and the third indication information during the ranging reporting phase of the current ranging round, the responding device may send the fourth indication information to the initiating device during the ranging reporting phase of the current ranging round; or, it may also start sending the fourth indication information to the initiating device before the ranging phase of the next ranging round begins (e.g., the control phase of the next ranging round). FIG12(b) shows an example of sending the fourth indication information to the initiating device and the responding device during the ranging result reporting phase of the current ranging round.
[0564] After step 1 to step 5, the initiating end device and the responding end device may transmit a UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform subsequent processes of the UWB ranging.
[0565] Alternatively, when the receiving device is a responding device for ranging, and the responding device is a controlling device in the ranging process, the controlling device may directly indicate the number of segmented signals of the UWB ranging signal, without having to determine the number of segmented signals of the UWB ranging signal based on the third indication information sent by the initiating device. For example, after executing steps 1 and 3 above, execute:
[0566] Step 4a: The responding end device sends fourth indication information to the initiating end device.
[0567] Step 4a includes two possibilities:
[0568] Possibility 1: The responding end device sends the fourth indication information in the current ranging phase, as shown in FIG12(c).
[0569] Possibility 2: The responding end device sends the fourth indication information during the ranging reporting phase, as shown in FIG12(d).
[0570] After step 1 to step 4a, the initiating end device and the responding end device may transmit a UWB ranging signal based on the determined number of segmented signals of the UWB ranging signal to perform subsequent processes of the UWB ranging.
[0571] The processes shown in FIG6 and FIG8 describe in detail how to determine the number of segment signals of the UWB signal transmitted in the measurement phase based on the UWB test signal and how to indicate the number of segment signals of the UWB signal.
[0572] As a possible implementation manner, the above-mentioned process of the transmitting end device determining the number of segmented signals of the UWB signal transmitted during the measurement phase is a process that does not require triggering.
[0573] As another possible implementation, the transmitting device determines the number of segmented signals of the UWB signal transmitted during the measurement phase based on a process triggered by a trigger request sent by the receiving device.
[0574] For example, the receiving device is a ranging responding device, and the transmitting device is a ranging initiating device. During the measurement reporting phase of the first round, if the responding device needs to change the number of segmented signals of the UWB signal transmitted during the measurement phase of a subsequent round (e.g., the second round), the reporting message related to the ranging result returned to the transmitting device (e.g., a narrowband signal) shall carry at least one of the following information:
[0575] A change request message, an updated number of segment signals (e.g., the FFNE IE message described above), information related to a change in the number of segment signals of the UWB signal, etc. The change request message is used to indicate a change in the number of segment signals of the UWB signal. For example, the change request message may be the RCR IE described above.
[0576] That is, the information related to the change in the number of segmented signals of the UWB signal can be combined with the reporting message related to the ranging result returned by the responding end device to the initiating end device and reported in one message.
[0577] For another example, if the receiving device needs to change the number of segmented signals of the UWB signal transmitted in the measurement phase of the subsequent round (e.g., the second round) during the measurement phase of the first round, the receiving device may send a change request message (e.g., a narrowband signal) to the transmitting device. The change request message is used to request a change in the number of segmented signals of the UWB signal transmitted in the measurement phase of the subsequent round (e.g., the second round). The change request message includes at least one of the following information:
[0578] A change request message, the updated number of segment signals (e.g., the FFNE IE message described above), information related to the change in the number of UWB blocks, etc. The change request message is used to indicate a change in the number of segment signals of the UWB signal. For example, the change request message can be the RCR IE described above.
[0579] This means that information related to the number of UWB signal segments is transmitted during the measurement phase, meaning it does not need to be combined with the ranging result report. For example, the order of the transmission time slots of the change request message and the UWB signal sent by the receiving device to the transmitting device can be interchanged to accommodate different scenarios.
[0580] For example, the change request message is sent after the receiving device sends the UWB signal to the sending device, which can be adapted to the scenario where the receiving device needs more time to process the segmented signal of the UWB signal from the initiator; for another example, the change request message is sent before the receiving device sends the UWB signal to the sending device, which can be adapted to the scenario where the receiving device needs to respond quickly to the sending device.
[0581] Furthermore, it should be noted that the aforementioned process for triggering an update of the number of UWB signal segments by a receiving device can be applied to other scenarios, meaning that the triggering process can be independent. For example, there is no restriction on the method used to determine the number of UWB signal segments prior to the change request. When a receiving device needs to change the number of UWB signal segments, the triggering process can be used to trigger an update of the number of UWB signal segments.
[0582] Illustratively, the method for determining the number of segmented signals of the UWB signal before the change request may be the aforementioned method based on the UWB test signal in the ranging control phase, or other existing or future methods for determining the number of segmented signals of the UWB signal.
[0583] For ease of understanding, the process of triggering the receiving device to update the number of segmented signals of the UWB signal is described in detail with reference to (e) to (g) in FIG. 12 .
[0584] Possibility 1: During the measurement result reporting phase of the current measurement round, the receiving device sends a change request message to the transmitting device to trigger an update of the number of segment signals of the UWB signal in the next measurement round.
[0585] In a first possibility, the change request message may be carried in a report message related to the ranging result, as shown in FIG12(e).
[0586] Possibility 2: During the measurement phase of the current measurement round, the receiving device sends a change request message to the transmitting device to trigger an update of the number of segmented signals of the UWB signal for the next measurement round, as shown in (f) and (g) of Figure 12 .
[0587] As shown in (f) and (g) of FIG12 , the change request message and the UWB signal sent by the receiving device to the transmitting device can be exchanged in the order of the sending time slots.
[0588] In the process for triggering an update of the number of segmented signals in a UWB signal shown in (e) to (g) of Figure 12 above, the receiving device is the responding device and the transmitting device is the initiating device; alternatively, the receiving device is the initiating device and the transmitting device is the responding device. Furthermore, in the cases shown in (e) to (g) of Figure 12, the transmitting device is the controlling device, which can also be a third party or the receiving device. The process is similar to that of (e) to (g) of Figure 12 and will not be further described.
[0589] It should be noted that the above-mentioned process of triggering the update of the number of segment signals of the UWB signal can be used in combination with the above-mentioned process of determining the number of segment signals of the UWB signal.
[0590] For example, with respect to the situation shown in FIG6 or FIG8, the transmitting end device receives a change request message from the receiving end device during the measurement result reporting phase and / or measurement phase of the previous measurement round before the number of segmented signals of the UWB signal is determined in the current measurement round. For example, the transmitting end device receives a change request message from the receiving end device before step S611; or
[0591] After determining the number of UWB signal segment signals in the current measurement round, the receiving device sends a change request message to the transmitting device during the measurement result reporting phase and / or measurement phase of the current measurement round to update the number of UWB signal segment signals 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.
