Description

Method and device for transmitting signaling

This application claims priority to the Chinese patent application filed with the China Patent Office on April 14, 2022, with application number 202210388761.3 and application title "Method and Device for Transmitting Signaling", the entire content of which is incorporated into this application by reference. .

Technical field

The embodiments of the present application relate to the field of communications, and more specifically, to a method and device for transmitting signaling.

Background technique

Ultra wideband (UWB) technology is a wireless carrier communication technology that uses nanosecond-level non-sinusoidal narrow pulses to transmit data. Because its pulses are very narrow and the radiation spectrum density is extremely low, the UWB system has the advantages of strong multipath resolution, low power consumption, and strong confidentiality.

Specifically, UWB technology can use a single waveform to achieve sensing while also carrying out ranging. However, the existing version of the protocol IEEE 802.15.4z lacks medium access control (MAC) support for sensing, and also lacks MAC support for using a single waveform to achieve simultaneous sensing and ranging. This will lead to additional signaling interaction overhead in UWB handover coordination between sensing and ranging services, reduce spectrum utilization, and limit the application potential of UWB technology for simultaneous sensing and ranging.

The current standard adopted by WPAN is the Institute of Electrical Engineering (Institute of Electrical Engineering). and electronics engineer, IEEE)802.15 series. WPAN can be used for communication between digital auxiliary equipment within a small range such as phones, computers, and accessory equipment. Its working range is generally within 10m.

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.

1. UWB technology: It is a wireless carrier communication technology that uses nanosecond-level non-sinusoidal narrow pulses to transmit data. Therefore, the frequency spectrum it occupies is very wide. Because its pulses are very narrow and the radiation spectrum density is extremely low, the UWB system has the advantages of strong multipath resolution, low power consumption, and strong confidentiality, which is conducive to coexistence with other systems, thereby improving spectrum utilization and system capacity.

With the Federal Communications Commission (FCC) approving UWB technology to enter the civilian field in 2002, ultra-wideband wireless communication has become one of the popular physical layer technologies for short-distance, high-speed wireless networks. Many world-famous large companies, research institutions, and standardization organizations are actively involved in the research, development, and standardization of ultra-wideband wireless communication technology. The Institute of Electrical and Electronics Engineers (IEEE) has classified UWB technology as Incorporated into its IEEE 802 series of wireless standards, the WPAN standard IEEE 802.15.4a based on UWB technology has been released, as well as its evolved version IEEE 802.15.4z. The formulation of the next-generation UWB technology WPAN standard 802.15.4ab has also been put on the agenda.

2. Perception: including but not limited to active sensing, passive sensing, one-way sensing and two-way sensing.

Among them, active sensing means: the sensing initiator actively initiates UWB sensing measurement, and the measurement signal passes through the target object to generate a reflected signal. The sensing response end receives the reflected signal generated by the target object, and responds to the channel impulse response (CIR) of the reflected signal. ) information or processed sensing result information is fed back to the sensing initiating end, and the sensing initiating end performs signal processing or forwarding on the received feedback information.

Passive sensing means: the sensing initiator does not actively initiate sensing measurements, but the sensing responder initiates sensing measurements. The measurement signal passes through the target object to generate a reflected signal. The sensing initiator receives the reflected signal from the target object and processes or forwards the CIR information of the reflected signal.

One-way sensing: For active sensing mode, the one-way sensing process includes: the sensing initiator initiates UWB sensing measurement, the sensing responder receives the reflected signal generated by the target object, and the sensing responder does not initiate sensing measurement in the reverse direction from the sensing initiator.

For the passive sensing mode, the difference between the one-way sensing process and the above-mentioned one-way sensing in the active sensing mode is that in the aforementioned description of the one-way sensing process in the active sensing mode, the roles of the sensing initiator and the sensing responder are interchanged, that is, Can.

Bidirectional sensing: For active sensing mode, the bidirectional sensing process includes: the sensing initiator initiates sensing measurement, the sensing responder receives the reflected signal generated by the target object, and generates the channel impact response information (CIR) of the reflected signal or processed sensing The result information is fed back to the sensing initiating end; the sensing response end can reversely initiate sensing measurement. The sensing initiating end receives the reflected signal generated by the target object and sends the channel impact response information (CIR) of the reflected signal or the processed sensing result information. , feedback to the sensing response end. This perception process is called two-way perception.

For the passive sensing mode, the difference between the two-way sensing process and the above-mentioned one-way sensing in the active sensing mode is that in the aforementioned description of the two-way sensing process in the active sensing mode, the roles of the sensing initiator and the sensing responder can be interchanged.

3. Business piggybacking: During the same business period, UWB measurement signals are used for more than one business at the same time. For example, UWB ranging signals are used for UWB sensing at the same time, UWB TWR ranging signals are used for UWB OWR ranging at the same time, etc.

4. Perception and piggyback ranging: Among the three characteristics of communication, ranging and sensing, UWB focuses more on ranging and sensing capabilities. The same UWB waveform can be used to realize sensing and piggyback ranging. The typical pulse waveform is a Gaussian windowed 8th order Butterworth pulse waveform. This pulse waveform has lower side lobe peaks, which is beneficial to the sensing function. In addition, the first path signal of this waveform is also significant and is also suitable for the ranging function, and the power spectral density of this waveform also meets the 802.15.4z version This waveform can be used to achieve simultaneous sensing and ranging.

In order to facilitate understanding, let’s briefly introduce the ranging and positioning system used in the above-mentioned ranging technology in conjunction with 3. Figure 2 is a schematic architectural diagram of a ranging and positioning system provided by an embodiment of the present application. As shown in Figure 2, the ranging and positioning system includes multiple devices (device 1 and device 2 in Figure 2), which can be the devices involved in the embodiments of this application, and each device at least includes a UWB module. Further, 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 the device contains a narrowband communication module, data can be transmitted between the narrowband communication modules of device 1 and device 2 through a wireless link.

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 that implements narrowband communication technology (such as Wi-Fi, Bluetooth, or Zigbee (Zigbee protocol) etc.) devices, chips or systems, etc. In a device (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 on one device or chip. The embodiments of the present application do not limit the UWB module and the narrowband communication module. implemented in the device. UWB technology enables communication devices with high data throughput and device positioning with high accuracy.

The equipment involved in this application may be a wireless communication chip, a wireless sensor or a wireless communication terminal. For example, user terminals, user devices, access devices, subscriber stations, subscriber units, mobile stations, user agents, and user equipment that support Wi-Fi communication functions. The user terminals may include various handheld devices with wireless communication functions, vehicle-mounted devices, etc. devices, wearable devices, Internet of things (IoT) devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment (UE), mobile stations (MS) ), terminal, terminal equipment, portable communications device, handset, portable computing device, entertainment device, gaming device or system, global positioning system device or any other device configured for network communications via a wireless medium Suitable equipment etc. In addition, the device can support the 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. The device can also support multiple wireless local area networks (WLAN) standards of the 802.11 family such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11be next generation.

5. Physical layer protocol data unit (PPDU): UWB technology does not require the use of carriers in the traditional communication system, but transmits data by sending and receiving extremely narrow pulses with nanoseconds or less. Therefore, The synchronization of transceiver devices is crucial in UWB technology. The so-called synchronization of transceiver devices can be understood as PPDUs being sent in the form of pulse signals. The receiving end determines which of the multiple received pulse signals it wants to receive. PPDU. Currently, the synchronization of transceiver devices is mainly achieved through the synchronization header (SHR) in the physical layer protocol data unit (PPDU). Specifically, the receiving end can perform correlation detection with the synchronization header. , thereby determining which of the multiple received pulse signals is the PPDU to be received.

Figure 3 is a schematic diagram of a PPDU frame structure. As shown in Figure 3, PPDU includes SHR, physical header (physical header, PHR) and physical layer (physical layer, PHY) bearer field (payload filed). Among them, SHR is used for PPDU detection and synchronization at the receiving end. Specifically, the receiving end can detect whether the sending end has sent a PPDU and the starting position of the PPDU based on SHR. PHR carries physical layer indication information, such as modulation and coding information. , PPDU length and the recipient of the PPDU, etc., to assist the receiving end in correctly demodulating the data, and the physical layer bearer field carries the transmission data.

6. Multi-node UWB downlink arrival time difference (Downlink Time difference of Arrival, DL-TDOA) Positioning: In order to facilitate the understanding of the positioning method, the positioning method will be described with reference to Figure 4. Figure 4 is a schematic diagram of a positioning method provided by an embodiment of the present application.

This method arranges three or more anchor point devices in space (A, B, and C as shown in Figure 4) to provide one-way ranging (One-Way Ranging, OWR) signals for tag devices. The tag device monitors the UWB positioning/ranging signals between anchor devices and calculates the arrival time difference between each signal to calculate its own position and implement the positioning function.

Specifically, periodic two-way UWB signal interaction can be performed between anchor devices, and the signal interaction behavior between anchor devices is similar to two-way ranging (TWR). Therefore, while providing DL-TDOA positioning services to tag devices, TWR services can be carried out between anchor devices. Among them, TWR can be Single-sided One-Way Ranging (SS-TWR) or Double-sided One-Way Ranging DS-TWR.

It can be seen from the above basic concepts that the same UWB waveform can be used to achieve sensing and ranging at the same time. However, the existing version of the protocol IEEE 802.15.4z lacks MAC support for sensing, and also lacks the ability to use a single waveform to achieve simultaneous sensing and ranging. MAC support. This will lead to additional signaling interaction overhead in UWB handover coordination between sensing and ranging services, reduce spectrum utilization, and limit the application potential of UWB for simultaneous sensing and ranging.

One way to implement sensing is to use 1 bit in the physical layer frame header PHR to indicate the use of sensing waveforms, thereby instructing the launch of sensing services.

Specifically, the PHR in this sensing mode is as shown in Table 1, and the 1 bit can be A1, A0 or the 12th bit in the table.

Table 1

Among them, SECDED means single-error correction, double-error detection (SECDED).

However, this sensing method only uses 1 bit to indicate the use of sensing waveforms at the PHR level, but fails to indicate the application mode that uses sensing and ranging at the same time. At the same time, as can be seen from Figure 3, the sensing indication carried out at the PHR layer of the PPDU frame structure cannot support the system MAC layer indication service piggyback mode, and thus cannot effectively use a single UWB waveform to carry out sensing and ranging services at the same time. Correspondingly, this approach also does not support the definition of functional roles of devices participating in the simultaneous sensing and ranging process.

In addition, the above-mentioned multi-node UWB DL-TDOA positioning method supports the anchor device to provide DL-TDOA positioning to the tag device and also carries out TWR ranging between the anchor devices, but does not support the application of sensing, and thus does not It supports simultaneous sensing and ranging functions.

On the other hand, the UWB DL-TDOA positioning method forwards the ranging function control to the beacon stage, and places the DL-TDOA positioning service period in the ranging management stage instead of the ranging stage, changing the existing version of the protocol. The timing structure will conflict with the ranging management services carried by the existing version of the protocol in the ranging management phase, which will lead to poor backward compatibility with existing ranging equipment. The UWB timing frame structure of the existing version protocol IEEE 802.15.4z is shown in Figure 5. Figure 5 is a schematic diagram of a UWB timing frame structure. Moreover, changing the control of the positioning service period to control at the beacon end will reduce the flexibility of positioning/ranging service control.

In order to support simultaneous UWB sensing and ranging, this application provides a method of transmitting signaling to provide UWB The MAC layer signaling indication and configuration methods support different service piggyback combination modes, such as sensing services and piggyback ranging services. The signaling transmission method provided by this application will be introduced in detail below with reference to the accompanying drawings.

The embodiments shown below do not specifically limit the specific structure of the execution body of the method provided by the embodiment of the present application, as long as it can be provided according to the embodiment of the present application by running a program that records the code of the method provided by the embodiment of the present application. It suffices to communicate by a method. For example, the execution subject of the method provided by the embodiment of the present application can be a transceiver device, or a functional module in the transceiver device that can call a program and execute the program.

In order to facilitate understanding of the embodiments of the present application, the following points are explained.

First, in this application, "for indicating" may include direct instructions and indirect instructions. When describing certain information to indicate A, it may include that the information directly indicates A or indirectly indicates A, but it does not mean that the information must contain A.

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. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the information to be indicated. Index of information, etc. The information to be indicated may also be indirectly indicated by indicating other information, where there is an association relationship 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 other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of a pre-agreed (for example, protocol stipulated) arrangement order of each piece of information, thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and indicated in a unified manner to reduce the instruction overhead caused by indicating the same information individually.

Second, the first, second and various numerical numbers (for example, "#1", "#2", etc.) shown in this application are only for convenience of description and are used to distinguish objects, and are not used to limit this application.

It is to be understood that objects so described are interchangeable where appropriate to enable description of aspects other than the embodiments of the present application.

Third, in this application, "preconfigured" may include predefined, for example, protocol definitions. Among them, "pre-definition" can be realized by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in the device (for example, including each network element). This application does not limit its specific implementation method.

Fourth, the “save” involved in the embodiments of this application may refer to saving in one or more memories. The one or more memories may be provided separately, or may be integrated in an encoder or decoder, a processor, or a communication device. The one or more memories may also be partially provided separately and partially integrated in the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application is not limited thereto.

Fifth, the term "and/or" in this article is only an association relationship that describes related objects, indicating that there can be three relationships. For example, A and/or B can mean: A alone exists, and A and B exist simultaneously. , there are three situations of B alone. In addition, the character "/" in this article generally indicates that the related objects are an "or" relationship.

Sixth, the "protocol" involved in the embodiments of this application may refer to a standard protocol in the field of communication. For example, it may include the WiFi protocol and related protocols applied in future communication systems. This application does not limit this.

In the following, without loss of generality, the signaling transmission method provided by the embodiments of the present application will be described in detail, taking the interaction between the sending end device and the receiving end device as an example.

As an example and not a limitation, the sending device may be a device with communication capabilities in the WPAN, such as FFD or RFD; similarly, the receiving device may also be a device with communication capabilities in the WPAN, such as FFD or RFD.

It should be understood that the specific types and names of the sending end device and the receiving end device are not limited in this application. UWB signal communication equipment can be used. The sending device can also be called the initiating device, and the receiving device can also be called the responding device.

Figure 6 is a schematic flow chart of a signaling transmission method provided by an embodiment of the present application, which includes the following steps:

S710, the sending device generates ARC IE.

The ARC IE includes a first field, which is used to indicate whether to enable a waveform that supports both ultra-wideband UWB sensing and ranging functions.

In this embodiment, the reserved field of the existing version protocol ARC IE is reused to indicate whether to enable a waveform that supports both ultra-wideband UWB sensing and ranging functions. The changes to the existing protocol version are minor and have strong backward compatibility. . It can support indicating whether to enable simultaneous sensing and positioning, thereby supporting the use of the same UWB signal to carry out multi-purpose services during the same working period, reducing the control signaling overhead caused by switching between control sensing and ranging services, and improving air interface efficiency and spectrum utilization. Rate.

Among them, the requirements for waveforms that support ultra-wideband UWB sensing and ranging functions are not described in detail in this application. Waveforms that can support UWB sensing and ranging functions are sufficient. The parameters that may be involved in the definition of ranging waveform requirements can be Refer to the parameters defined in current protocols (such as IEEE 802.15.4z) for waveforms that support ranging; for parameters that may be involved in the definition of requirements for sensing waveforms, refer to the parameters for waveforms that support sensing in the 802.15.4ab protocol or subsequent versions. defined parameters.

Optionally, in this embodiment, the ARC IE can be called an advanced ranging control cell, or it can also be called an advanced sensing and ranging control cell, or it can also be called a first cell. It should be understood that in this application There is no restriction on the name of the information (or cell, message, etc.), as long as it can realize the corresponding function.

Exemplarily, in the embodiment of the present application, for the ARC IE specified by the IEEE 802.15.4z protocol (as shown in Table 2), the reserved bits in the ARC IE Content Control field (as shown in Table 3) are used. At least one bit to configure the simultaneous sensing and ranging process.

Table 2

table 3

As a possible implementation, the above-mentioned first field is one of the reserved bits of ARC IE. Among them, the first field may be called the Enabling Unified Waveform (Enabling Unified Waveform, EUW) field.

For example, define 1 reserved bit of ARC IE (for example, the first bit in the reserved bit) as the EUW field. The meaning of the EUW field is defined as shown in Table 4 below:

Table 4:

It should be noted that in the case of EUW=1, it means that the waveform that supports both ultra-wideband UWB sensing and ranging functions is enabled, and the waveform that supports both ultra-wideband UWB sensing and ranging functions can be as shown in Table 1 UWB waveforms that meet the requirements of subsequent versions of protocols such as IEEE 802.15.4ab and can support simultaneous sensing and ranging can also be waveforms of existing protocols such as IEEE 802.15.4a and/or IEEE 802.15.4z. However, the performance of simultaneous sensing and ranging based on waveforms based on existing protocols such as IEEE 802.15.4a and/or IEEE 802.15.4z is not as good as the performance of simultaneous sensing and ranging based on new waveforms defined by 802.15.4ab.

It should be understood that the above-mentioned first field is 1 reserved bit in the ARC IE field, which is only an example and does not constitute any limitation on the protection scope of the present application. The first field can also occupy more than 1 bit in the reserved bits. This is not the case. Let’s give examples one by one. In addition, the EUW field values and meanings shown in Table 4 are only examples and do not constitute any limitation. It can also be that when the EUW field value is 0, it means using a waveform that can meet the requirements of simultaneous sensing and ranging, and when the EUW field value is 1, it means Use UWB ranging waveforms that meet existing IEEE 802.15.4z ranging functional requirements.

It should also be understood that the above-mentioned UWB sensing and ranging function combination mode is only an example and does not constitute any limitation on the protection scope of the present application. The first field can also be used to indicate whether to support other service piggyback combination modes (such as sensing and communication). ).

It should also be understood that the above-mentioned ARC IE is also an example and does not constitute any limitation on the scope of protection of this application. The transmitting device can indicate through other signaling whether to enable a waveform that simultaneously supports ultra-wideband UWB sensing and ranging functions, for example, multiplexing Existing signaling other than ARC IE, or new signaling, will not be explained one by one here.

In this embodiment, the first field is used to indicate whether to enable a waveform that supports both ultra-wideband UWB sensing and ranging functions. Compared with the previous description of using 1 bit in the physical layer frame header PHR to indicate the use of the sensing waveform For the solution, ARC IE is used at the MAC layer to indicate the simultaneous development of sensing and ranging services, instead of only instructing the development of sensing services. Therefore, the solution of this application has richer service indication capabilities.

For example, the reserved bits of the above-mentioned ARC IE may also include a second field, and the second field is used to indicate the piggyback mode.

As a possible implementation, when the first field indicates that a waveform that supports both UWB sensing and ranging functions is not enabled, the second field is used to indicate a first mode, and the first mode includes measuring distance (such as TWR or OWR) and no traffic piggybacking, two-way ranging TWR piggybacking on one-way ranging OWR, where two-way ranging TWR includes SS-TWR or DS-TWR.

As another possible implementation, in the case where the first field indicates enabling a waveform that supports both UWB sensing and ranging functions, the second field is used to indicate a second mode, and the second mode includes sensing (such as OWS or TWS) and there is no traffic piggybacking, perception piggybacking TWR, or perception piggybacking OWR.

As yet another possible implementation, when the first field indicates enabling a waveform that simultaneously supports UWB sensing and ranging functions, the second field is used to indicate a third mode, and the third mode includes two-way Perception carries two-way ranging TWR and one-way ranging OWR.

Optionally, the above-mentioned second field is the middle two bits of the reserved bits of the ARC IE. The second field may be called a Services Piggybacking Mode (SPM) field.

For example, the 2 reserved bits of ARC IE are the SPM field. The meaning of the SPM field is defined as shown in Table 5 below:

table 5

For example, when it is not considered that TWS carries TWR and OWR at the same time, the above-mentioned second field may be a field occupying one bit in the reserved field. The above Table 5 can be simplified to the following Table 5a:

Table 5a

It should be understood that the specific positions of the above-mentioned EUW and SPM can be any 3 bits among the 4 reserved bits in the ARC IE Content Control field.

Further, in this embodiment, the Ranging Round Usage field of ARC IE can be redefined.

For example, in the case where the first field indicates that a waveform that supports both sensing and ranging functions is not enabled and the second field indicates the first mode, the Ranging Round Usage field included in the ARC IE ) is used to indicate any of the following: perform one-way ranging OWR, perform one-sided two-way ranging SS-TWR, or perform two-sided two-way ranging DS-TWR.

For another example, in the case where the first field indicates that a waveform that supports both sensing and ranging functions is not enabled and the second field indicates a second mode, the ranging wheel usage field (Ranging Round) included in the ARC IE Usage) is used to indicate either of the following: execute SS-TWR with OWR, or execute DS-TWR with OWR.

For another example, in the case where the first field indicates enabling a waveform that supports both sensing and ranging functions, and the second field indicates a first mode, the ranging wheel usage field included in the ARC IE is used to indicate execution One-way aware OWS or two-way aware TWS.

For another example, the first field indicates enabling a waveform that supports both sensing and ranging functions, and the second field indicates When the second mode is displayed, the ranging round usage field included in the ARC IE is used to indicate any of the following: executing OWS piggybacking OWR, executing OWS piggybacking SS-TWR, or executing OWS piggybacking DS-TWR.

For another example, in the case where the first field indicates enabling a waveform that supports both sensing and ranging functions, and the second field indicates the third mode, the ranging round usage field included in the ARC IE is used to indicate Execute TWS with SS-TWR and OWR, or execute TWS with DS-TWR and OWR.

For ease of description, the following table explains the meaning of the Ranging Round Usage field of ARC IE.

As a possible implementation method, when EUW=0, the meaning of the Ranging Round Usage field of ARC IE is redefined as shown in the following table:

Table 6:

Among them, it can be seen from Table 6 that when EUW=0 and SPM=00, the definition of the Ranging Round Usage field is the same as the definition of Ranging Round Usage in the existing version protocol 802.15.4z. Therefore, in the many-to-many node mode, the existing version protocol equipment can still parse the corresponding control commands and configurations normally, and carry out the corresponding ranging services. Therefore, compared with the second prior art, the solution of the present invention has smaller changes to the existing protocol version and has strong backward compatibility.

As another possible implementation, when EUW=1, the meaning of the Ranging Round Usage field of ARC IE is redefined as shown in the following table:

Table 7: Redefinition of the Ranging Round Usage field of ARC IE when EUW=1

It should be noted that when instructed to perform OWR, three or more anchor devices provide OWR signals to the tag device (the scenario shown in Figure 4), and the tag device listens to the UWB interaction between the anchor devices. signals, and calculates the arrival time difference between each signal, thereby calculating its own position and realizing the positioning function. That is to say, when OWR is instructed to be executed, TDOA (eg, DL-TDOA) positioning service can be provided for the tag device. Specifically, how to perform positioning based on the OWR method may refer to the description of positioning based on the OWR method in current related technologies, which will not be described again here.

Specifically, in this embodiment, after the sending device generates the ARC IE, it sends the ARC IE to the receiving device. The method flow shown in Figure 6 also includes:

S720, the sending device sends ARC IE to the receiving device.

It should be understood that in this embodiment, there is no limitation on the way in which the sending device sends the ARC IE to the receiving device. Reference can be made to the description in the current related art, which will not be described again here.

Further, in this embodiment, after the receiving device receives the ARC IE, it can parse the ARC IE and determine whether to enable a waveform that supports both ultra-wideband UWB sensing and ranging functions. The method flow shown in Figure 6 also includes:

S730: The receiving device determines whether to enable a waveform that supports both ultra-wideband UWB sensing and ranging functions.

Specifically, the receiving device can determine whether to enable a waveform that supports both ultra-wideband UWB sensing and ranging functions based on the first field in the ARC IE.

It should be understood that the receiving end device determines whether to enable a waveform that simultaneously supports ultra-wideband UWB sensing and ranging functions based on the first field by: determining based on the value of the first field (as shown in Table 4 above), specifically the first For the definition of the meaning of the field value, please refer to the description of the first field in the ARC IE generated by the sending device, which will not be described again here.

For example, when the reserved bits of the ARC IE include the second field, the receiving device can determine the piggyback mode based on the second field. The method flow shown in Figure 6 also includes:

S740, the receiving end device determines the piggyback mode.

Specifically, the meaning of the second field can be defined with reference to the description of the second field in the ARC IE generated by the sending device (as shown in Table 5 and Table 5a above), which will not be described again here.

In addition, from the above description of the sending device generating ARC IE, it can be seen that in this embodiment, the Ranging Round Usage field in the ARC IE can be redefined, and the receiving device can obtain the time when the sending device generates the ARC IE when parsing the Ranging Round Usage field. Determine the meaning of the Ranging Round Usage field.

Specifically, the definition of the meaning of the Ranging Round Usage field can refer to the description of the Ranging Round Usage field in the ARC IE generated by the sending device (as shown in Table 6 and Table 7 above), which will not be described again here.

Further, when a waveform that supports both ultra-wideband UWB sensing and ranging functions is enabled, the functional role of the device can be defined through new signaling. The method flow shown in Figure 6 also includes:

S750, the sending device sends SDM IE to the receiving device.

The SDM IE includes sensing role information and sensing mode information, where the sensing role information is used to indicate that the receiving end device is a sensing sending end or a sensing receiving end, and the sensing mode information is used to indicate active sensing or passive sensing.

Illustratively, the newly added SDM IE is the reuse of the reserved list rows in the nested IE list defined in Table 7-18 (Table-7-18) of the 802.15.4z protocol, where the elements in the list row Including: IE's sub-ID value (Sub-ID value), IE name (name), IE type, object using the IE (Used by) (such as upper layer protocol (Upper Layer, UL)), and the object that generated the IE (Created by) (Upper Layer (UL)) etc. Among them, IE types include: data type (Data), enhanced beacon type, enhanced confirmation message type, multi-purpose type, etc.

The newly added SDM IE can be identified and processed by devices that need to perform sensing functions. The corresponding identification and processing methods are similar to the identification and processing methods of RDM IE specified in the existing protocol 802.15.4z. Please refer to the existing protocol 802.15.4z. How to identify and deal with RDM IE.

For example, the upper layer of the sending device protocol configures SDM IE and passes it to the sending device MAC layer.

For example, the MAC layer of the receiving device passes the received SDM IE to the upper layer protocol of the receiving device, and the upper layer of the protocol identifies and processes the SDM IE.

As a possible implementation, the newly added SDM IE can be delivered through narrowband frequency bands.

As another possible implementation, the newly added SDM IE can also be delivered through the UWB frequency band.

For ease of understanding, the new SDM IE is introduced in detail below in conjunction with Table 7a.

Table 7a below is an expansion and continuation of Table 7-18 (Table 7-18) of the existing 802.15.4z protocol. For the sake of simplicity, the existing definitions of Table 7-18 in the protocol are not reflected in Table 7a below. Specifically, as can be seen from Table 7a below, the new SDM IE can be added to the nested IE list defined in Table 7-18 (Table 7-18) of the existing 802.15.4z protocol as the 802.15.4ab protocol Or the new IE in subsequent versions of the agreement. Specifically, a reserved sub-ID value (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 new SDM IE .

Table 7a:

Among them, T in the table can be any one or more values from 0x5d-0x7f. This Table 7a can be an expansion and continuation of the nested IE list defined in the existing 802.15.4z protocol Table-7-18 (Table-7-18). The X in Table 7a indicates that the SDM IE belongs to the Data type IE.

Exemplarily, the sensing role information and sensing mode information are carried in a list (SDM List) field in a sensing device management (Sensing Device Management, SDM) information element (IE), and the SDM List field Also included is the following information:

Sensing slot index (Sensing Slot Index) information, address information (Address) and reserved (Reserved) fields, where the sensing slot index information is used to indicate the corresponding time slot of the UWB signal, and the address information is used to Indicates the address of the receiving end device. The address of the receiving end device can also be understood as the address of the interface (eg, receiving unit) of the receiving end device.

The SDM IE also includes the following fields:

The slot index uses (Slot Index Used, SIU) field, address size (Address Size) field and SDM List Length field, wherein the SDM List Length field is used to indicate the number of list elements in the list field, and the The SIU field is used to indicate whether the current sensing mode is based on competition between devices or based on scheduling;

When the SIU is 0, the SDM IE is used to configure the sensing device role indication based on the competition mode. At this time, the Sensing Slot Index in the SDM List Length field is a reserved field and is not used;

When the SIU is 1, the SDM IE is used to configure the sensing device role indication based on the scheduling mode. At this time, the Sensing Slot Index in the SDM List Length field will be enabled to indicate the device sensing transceiver time slot, and the Address Size field is used Address size type for the indication list field; if Address Size is 0, the sensing device uses a short address; if Address Size is 1, the sensing device uses a long address.

As a possible implementation method, when EUW=0, the Ranging Device Management (RDM) information element (IE) of the existing version of the protocol is used to define the functional role of the UWB device node. Table 8 and Table 9 below are examples of existing RDM IE:

Table 8

Table 9

Specifically, the definition of the RDM IE specified in the existing protocol may refer to the description of the existing protocol, which will not be described again in the embodiments of this application.

As another possible implementation, when EUW=1, the present invention uses the newly defined sensing device management information element SDM IE to define its functional role for the UWB device node. Table 10 and Table 11 below show the SDM IE:

Table 10

Table 11

The following describes the sensing role information and sensing mode information fields in SDM IE in detail in conjunction with (a) and (b) in Figure 7 and Table 12 (such as Sensing Role and Sensing Mode shown in Table 11).

Exemplarily, (a) in Figure 7 shows the active sensing mode. Specifically, the sensing initiating end actively initiates UWB sensing measurement, the measurement signal passes through the target object and generates a reflection signal, and the sensing response end receives the reflection generated by the target object. signal, and feeds back the CIR information of the reflected signal or the processed sensing result information to the sensing initiating end, and the sensing initiating end performs signal processing or forwarding on the received feedback information. (b) in Figure 7 shows the passive sensing mode. Specifically, the sensing initiator does not actively initiate sensing measurement, but the sensing responder initiates sensing measurement. The measurement signal passes through the target object to generate a reflected signal. The sensing initiator receives the reflected signal from the target object and processes or forwards the CIR information of the reflected signal.

Sensing Role The rules used to define the functional roles of UWB node devices are shown in Table 12 below:

Table 12

It can be seen from the active sensing mode shown in (a) in Figure 7 that if the device receiving the SDM IE is the sensing receiver (the sensing responder, the device that receives the UWB signal), but the sensing receiver does not perform sensing measurements, Instead, the CIR information of the reflected signal or the processed sensing result information is fed back to the sensing initiating end, and the sensing initiating end performs signal processing or forwarding on the received feedback information. Then in the active sensing mode, if SPM=01 (indicating sensing with TWR or OWR), the device that receives the SDM IE determines to perform sensing and ranging, and the device is the ranging responder device;

On the contrary, in the active sensing mode, if the device receiving the SDM IE is a sensing transmitter (a device that sends UWB signals), then the device performs sensing measurement. If SPM=01 (indicating sensing piggybacking TWR or OWR), the device receives The SDM IE device determines to perform sensing and incidental ranging, and this device is the ranging initiating device.

From the passive sensing mode shown in (b) of Figure 7, it can be known that if the device that receives the SDM IE is a sensing receiver (a device that receives UWB signals), then the device performs sensing measurements. If SPM=01 (indicating sensing with TWR or OWR), the device that receives the SDM IE determines to perform sensing and ranging, and the device is the ranging initiator device.

On the contrary, in passive sensing mode, if the device receiving the SDM IE is a sensing sender (a device that sends UWB signals), then the device does not perform sensing measurements. If SPM=01 (indicating sensing piggybacking TWR or OWR) the device that receives the SDM IE determines to perform sensing and piggyback ranging, and the device is a ranging responder device.

By introducing the newly defined SDM IE, it can be used to determine the functional role of device nodes in the simultaneous sensing and ranging process, support simultaneous sensing and ranging, and enhance the functions of the existing version of the protocol.

It should be understood that the above-mentioned signaling that carries sensing role information and sensing mode information is called SDM IE is just an example, and does not constitute any limitation on the protection scope of this application. Other signaling including sensing role information and sensing mode information are all included in this application. Within the scope of protection applied for, no examples will be given here.

In order to facilitate understanding, the method flow shown in Figure 6 is described with reference to specific examples.

Example 1: Figure 8 is a schematic diagram of a UWB sensing piggyback ranging service provided by an embodiment of the present application. The tag device shown in Figure 8 is a tag device with strong computing capabilities, such as a UWB tag device carried on a smart terminal. For example, the tag device can be an FFD. The anchor device can also be a tag device with strong computing capabilities. The (coordinator/service) requester can also be an anchor device. TWR can be SS-TWR or DS-TWR. The sensing service can be OWS or TWS, and it can be active sensing or passive sensing. In the piggybacking mode, whether EUW=0 or EUW=1, messages related to the piggybacked business will be triggered, such as: measurement message reporting, necessary assistance Management information (node spatial coordinates, etc.), synchronization offset correction, etc.

For example, in Figure 8, the OWR ranging service can be used to implement the DL-TDOA positioning service on the tag device side. For example, anchor point B, anchor point C and anchor point D provide OWR signals for the tag device (eg, Figure 8 Anchor point B, anchor point C, and anchor point D shown in point to the signal flow of the tag device). The tag device monitors the UWB signals between the anchor point devices and uses auxiliary information such as the arrival time difference between each signal, thereby Calculate its own position and implement positioning function. Specifically, how to perform positioning based on the OWR method and how to calculate one's own position based on auxiliary information such as the arrival time difference between each signal, you can refer to the current relevant technology regarding positioning based on the OWR method and auxiliary information based on the arrival time difference between each signal. The description of calculating its own position will not be repeated here.

In this implementation, the ranging service between any two anchor points in Figure 8 can be used to implement TWR ranging (the signal flow between anchor point B and anchor point C shown in Figure 8, or the anchor point The signal flow between B and anchor point D), that is to say, ranging and piggyback positioning can be achieved.

In this implementation, the sensing function can be realized between the anchor point and the sensing target object in Figure 8 (for example, the signal flow between the anchor point B and the sensing target object shown in Figure 8), that is to say, sensing piggybacking can be achieved Positioning, or perception piggybacking ranging, or perception piggybacking positioning and ranging.

It should be noted that in the above embodiment shown in Figure 6, the reserved bits in the ARC IE defined in the existing protocol are reused to indicate whether to enable the waveform that simultaneously supports ultra-wideband UWB sensing and ranging functions, and to indicate piggybacking mode, and redefine the Ranging Round Usage field in ARC IE to implement instructions to perform different functions (such as ranging, sensing or sensing piggyback ranging). This is just an example. This application also provides the following signaling indication methods to facilitate Implementation instructions perform different functions.

For example, the sending device sends an ARC IE to the receiving device. The fields in this ARC IE include the following values:

The first value is used to instruct the execution of OWR; the second value is used to instruct the execution of SS-TWR; the third value is used to instruct the execution of DS-TWR; the fourth value is used to instruct the execution of SS-TWR and OWR; the fifth value is used to instruct the execution of SS-TWR. The value is used to instruct the execution of DS-TWR and OWR; the sixth value is used to instruct the execution of OWS; the seventh value is used to instruct the execution of TWS; the eighth value is used to instruct the execution of OWS and OWR; the ninth value is used to instruct the execution of OWS and OWR. Instructs the execution of TWS piggybacking SS-TWR; the tenth value is used to instruct the execution of TWS piggybacking DS-TWR; the eleventh value is used to instruct the execution of TWS piggybacking SS-TWR and OWR; the twelfth value is used to instruct the execution of TWS piggybacking DS-TWR and OWR.

Illustratively, the meanings indicated by the above different values (for example, the first value to the twelfth value) are predefined by the protocol. For example, the receiving end device and the sending end device locally save the following table 13; or, the above different values The meaning indicated by the value is determined by the agreement between the receiving device and the sending device. For example, the receiving device and the sending device obtain the following table 13 through negotiation.

Table 13

From the above, the receiving end device and the transmitting end device know the different values (for example, the first value to the twelfth value) shown in the above Table 13, and the corresponding relationship between the meanings indicated by the different values. In this case, the sending device can indicate through the fields in the ARC IE (or new information elements) that the above values have reached the purpose of indicating the execution of different functions.

As a possible implementation, the fields in the ARC IE can be the reserved bits of the ARC IE specified in the current protocol.

Specifically, 4 bits in the reserved bits of the multiplexed ARC IE indicate the above-mentioned first to twelfth values. For example, 0000 represents the first value, 0001 represents the second value, 0010 represents the third value, 0100 represents the fourth value, 1000 represents the fifth value, 0011 represents the sixth value, 0101 represents the seventh value, 1001 represents the eighth value, 0110 represents the ninth value, 1100 represents the tenth value, 0111 represents the eleventh value, and 1110 represents the twelfth value.
