This application relates to the communication field, and in particular, to a monostatic sensing method and a related product.

The WLAN sensing is to sense surrounding environments by using a radio frequency (RF) signal sent by a WLAN device, and extract corresponding parameters in a received signal for analysis according to a specific algorithm, to obtain related information about the surrounding environments.

An embodiment of this application provides a monostatic sensing method that may be applied to a wireless communication system. The wireless communication system may be a wireless local area network or a cellular network. The method may be implemented by a communication device in the wireless communication system or a chip or a processor in the communication device. The communication device may be a personal basic service set control point (PBSS control point, PCP), an access point (AP) device, or a station (STA) device.
In this application, an apparatus for implementing the method in this application may be a PCP/AP or a STA in a WLAN, or a chip or a processing system installed in the PCP/AP or the STA.
The PCP/AP is an apparatus having a wireless communication function, supports communication according to a WLAN protocol, and has a function of communicating with another device (for example, a station or another access point) in the WLAN. The PCP/AP may further have a function of communicating with another device. In a WLAN system, an access point may be referred to as an access point station (AP STA). The apparatus having the wireless communication function may be an entire device, or may be a chip, a processing system, or the like installed in the entire device. The device on which the chip or the processing system is installed may implement a method and function in embodiments of this application under control of the chip or the processing system. The PCP/AP in embodiments of this application is an apparatus providing a service for the STA, and supports the 802.11 series protocols.

For example, the STA may be user equipment that can connect to the internet, for example, a tablet computer, a desktop computer, a laptop computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a personal digital assistant (PDA), or a mobile phone. Alternatively, the STA may be an internet of things node in the internet of things, a vehicle-mounted communication apparatus in the internet of vehicles, an entertainment device, a game device or system, a global positioning system device, or the like. The STA may alternatively be a chip or a processing system in the foregoing terminals.
The following first describes terms and technical features in embodiments of this application.
1. 802.11bf
IEEE 802.11bf is a next-generation wireless standard that focuses on sensing of a passive object (that is, a target does not carry any device). According to 11bf, based on a received signal, corresponding parameters (such as a speed, a distance, and an angle) of the target are estimated and a subsequent action/behavior is recognized. 802.11bf includes two main types of standards: a standard for a low frequency (sub-7 GHz, where implementation of the standard is mainly based on 11ac, 11ax, 11be, a next-generation standard, and the like) and a standard for a high frequency (60 GHz, where implementation of the standard is mainly based on 11ad, 11ay, a next-generation standard, and the like). The technical solutions of this application are applicable to the high frequency (11ad/DMG and 11ay/EDMG), or applicable to the low frequency (the standard corresponding to sub-7 GHz).
Because attenuation of a high-frequency electromagnetic wave is higher, in an existing high-frequency standard DMG/EDMG, a directional beam is usually used for sending and reception. This is a huge difference between the high-frequency standard and the standard of the low-frequency sub-7 GHz. However, compared with the low frequency, the high frequency has a larger bandwidth, a higher carrier frequency, and better sensing performance. For directional sending, some angle information may be provided, and interference may be reduced to some extent. This helps improve sensing performance.
In the high frequency (11ad, 11ay) in 802.11bf, monostatic, bistatic, and multistatic sensing modes are supported.
The monostatic mode is a sensing mode in which a same device is used for transmission and reception. In this mode, both transmission and reception are performed by a same device. Therefore, better (time and frequency) synchronization can be achieved, and sensing performance is good.
The bistatic mode is a sensing mode in which transmission and reception are separated, and may also be referred to as passive sensing. That is, transmission and reception are performed by two devices that operate independently. In this mode, transmission and the reception are not performed by a same device, and sensing performance may be potentially affected (by asynchronization).
The multistatic mode is a sensing mode that includes one transmitter/multiple transmitters and multiple receivers, or includes multiple transmitters and one receiver/multiple receivers. In this mode, a plurality of devices operate together. That is, this mode is a hybrid operating mode including a plurality of monostatic modes/bistatic modes.
2. Beacon Interval (BI) in 802.11ad/ay
In 802.11ad/ay, a time axis is divided into BIs.
Specifically, a PCP/AP sends a plurality of beacon frames in the BTI based on a sector number. The beacon frames are used for downlink sector sweep. A-BFT is used by a STA for association and uplink sector sweep. An ATI is used by the PCP/AP to poll the STA for buffered data information and allocate a resource in the data transmission interval (DTI) to the STA. The entire DTI is divided into several subintervals, and the subintervals are divided into a contention-based access period (CBAP) and a service period (SP) based on an access manner. In the service period, transmission scheduling is performed without contention.
An AP first carries a sensing short capability element in a beacon. This indicates that the AP supports passive sensing. If a STA in an environment is to use, for sensing, beacon information sent by the AP, the STA may send an information request frame to the AP, to request the AP to send information related to the beacon. The AP sends sending information (such as a sending time and a sending beam direction) of the beacon to the STA by using an information response frame. The STA may receive, by using the information, the beacon sent by the AP, and perform passive sensing based on the sending information of the beacon.
Beam training in 802.11ad is mainly performed during association beamforming training (A-BFT). First, in a BTI phase, a PCP/AP sends a beacon frame in each direction. An A-BFT length field in the frame indicates a total slot length of an A-BFT phase. STAs receiving the frame randomly select a slot from [0, A-BFT Length−1] in a next A-BFT phase for access, and then sequentially send SSW frames through directional antennas (that is, RXSS). In this case, the PCP/AP uses a quasi-omnidirectional antenna to receive beams from all directions and records optimal transmission beams of the STAs. Subsequently, in a sector sweep feedback (SSW Feedback) phase, the PCP/AP feeds back training information of the previous phase (RSS) to the STAs through directional beams. The feedback information is an initiator transmit sector list obtained through sorting by sector quality, and includes an optimal sector of a responder in the previous phase. In this case, the responder is in a quasi-omnidirectional reception mode. A sector sweep acknowledgment (SSW ACK) phase is the final phase. The SSW ACK phase may not exist when SLS is performed before a data transmission phase (DTI), but the SSW ACK phase is required when SLS is performed in the DTI phase. In the SSW ACK phase, the STAs feed back a responder transmit sector list obtained through sorting by quality.
In addition, to meet access training requirements of more users, an EDGM STA type is added to 802.11ay. A difference between the EDGM STA type in 802.11ay and a conventional DGM STA in 802.11ad lies in that the EDGM STA can transmit both an SSW frame and a short SSW frame in an A-BFT slot planned in an A-BFT phase. Compared with the SSW frame, the short SSW frame has a shorter frame length, so that the EDGM STA can transmit more data in one slot.
The first device may be the PCP/AP or the STA. If the first device is the PCP/AP, the first frame structure includes one of the following: a DMG beacon frame, a data frame, or a BRP. If the first device is the STA, the first frame structure is one of the following: a sector sweep SSW, a short SSW, a BRP, or a data frame. A training field (TRN) may be carried at the end of the first frame structure, and sensing is facilitated because the TRN is used for sweep.
For example, when the PCP/AP has a monostatic sensing capability, the PCP/AP may perform monostatic sensing based on the DMG beacon frame, the data frame, or the BRP, to obtain the first sensing result. When the STA has the monostatic sensing capability, the STA may perform monostatic sensing based on the SSW, the short SSW, the data frame, or the BRP, to obtain the first sensing result.
In a possible design, the first device may perform, to obtain the first sensing result, monostatic sensing based on the first frame structure sent by the first device, and send the first sensing result to the second device. To be specific, optionally, the second device may request, by using the first request frame, to obtain the monostatic sensing result from the first device, and the first device sends the first sensing result to the second device by using the first response frame. Optionally, the first request frame may be a DMG sensing poll frame or an information request frame. Further, the second device may perform passive sensing based on the first frame structure sent by the first device. The second device may request, from the first device, target beam information for sending the first frame structure by the first device and information about a target location of the first device for sending the first frame structure. The target beam information includes but is not limited to a horizontal beam direction, a vertical direction, a horizontal beam width, a vertical beam width, a beam gain, and other information. The target location information includes but is not limited to information about an orientation posture of the first device for sending the first frame structure. It should be noted that the location information may be location coordinates determined by using the first device as an origin of coordinates or by using other coordinates as an origin of coordinates. Correspondingly, the first device sends the target beam information and the target location information to the second device. The second device may not only perform passive sensing based on the first frame structure, the target beam information, and the target location information, but also parse or interpret the obtained first sensing result by using the target beam information and the target location information, to implement passive sensing and monostatic sensing based on a same procedure. In this way, sensing efficiency is improved, and repeated transmission of the beam information and the location information is avoided. Further, the second device may further perform comprehensive sensing based on the monostatic sensing result and a passive sensing result that are sent by the first device. In this way, sensing diversity gains at a same moment are increased and sensing performance improved.
In another possible design, the first device may announce that monostatic sensing is to be performed based on the first frame structure, and the second device may request, by using the first request frame, the first sensing result of monostatic sensing from the first device. Optionally, the first request frame may be the DMG sensing poll frame. To be specific, optionally, if the first device is the PCP or the AP, the first frame structure may be a DMG beacon frame in a current or next BTI. That is, the PCP or the AP announces that monostatic sensing is being performed based on the DMG beacon frame in the current BTI, or monostatic sensing is to be performed based on the DMG beacon frame in the next BTI. After the current or next BTI ends, the STA may request, from the PCP or the AP, the first sensing result of performed monostatic sensing. The first frame structure may alternatively be a data frame in a current or next DTI. That is, the PCP or the AP announces that monostatic sensing is being performed based on the data frame in the current DTI, or monostatic sensing is to be performed based on the data frame in the next DTI. After the current or next DTI ends, the STA may request, from the PCP or the AP, the first sensing result of performed monostatic sensing. The first frame structure may alternatively be a BRP in a current or next DTI. That is, the PCP or the AP announces that monostatic sensing is being performed based on the BRP in the current DTI, or monostatic sensing is to be performed based on the BRP in the next DTI. After the current or next DTI ends, the STA may request, from the PCP or the AP, the first sensing result of performed monostatic sensing.
If the first device is the STA, the first frame structure may be an SSW or a short SSW in current or next A-BFT. That is, the STA announces that monostatic sensing is being performed based on the SSW or the short SSW in the current A-BFT, or monostatic sensing is to be performed based on the SSW or the short SSW in the next A-BFT. After the current or next A-BFT ends, the PCP or the AP may request, from the STA, the first sensing result of performed monostatic sensing. The first frame structure may alternatively be a data frame in a current or next DTI. That is, the STA announces that monostatic sensing is being performed based on the data frame in the current DTI, or monostatic sensing is to be performed based on the data frame in the next DTI. After the current or next DTI ends, the PCP or AP may request, from the PCP or the AP, the first sensing result of performed monostatic sensing. The first frame structure may alternatively be a BRP in a current or next DTI. That is, the STA announces that monostatic sensing is being performed based on the BRP in the current DTI, or monostatic sensing is to be performed based on the BRP in the next DTI. After the current or next DTI ends, the PCP or the AP may request, from the STA, the first sensing result of performed monostatic sensing.
It should be noted that, to interpret the first sensing result, the second device may further request, from the first device, the target beam information for sending the first frame structure and the information about the target location of the first device for sending the first frame structure.
In this possible implementation, the second device may perform passive sensing, or may not perform passive sensing, that is, monostatic sensing is not bound to passive sensing. In this way, flexibility of a monostatic sensing manner is improved.
In some implementations, the first device sends the third information and the fourth information, where the third information is used to announce that the first device has the monostatic sensing capability, or the third information indicates that the first device supports monostatic sensing. The fourth information is used to announce that the first device has the passive sensing capability, or the fourth information indicates that the first device supports passive sensing, and another device may request sending beam information and location information from the first device. The first device may send the third information and the fourth information through broadcasting, multicasting, or unicasting. Correspondingly, the second device receives the third information and the fourth information.
The third information and the fourth information may be included in a second frame structure. Optionally, the third information and the fourth information may be included in a capability element field of the second frame structure, for example, a DMG short sensing capability element field.
In a first optional implementation, the first device is the PCP/AP, and the PCP/AP performs monostatic sensing based on the beacon frame or the BRP, that is, the first frame structure is the DMG beacon frame or the BRP.
In the DMG short sensing capability element field of the second frame structure, the PCP/AP may announce that the PCP/AP has the monostatic sensing capability. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a DMG beacon frame, an information request frame, an information response frame, a probe request frame, a probe response frame, or the like.
A structure of the DMG sensing short capabilities element field may have a structure shown in
In this embodiment of this application, the monostatic sensing support subfield is added to the short sensing capabilities field for determining whether the AP supports monostatic sensing. If passive sensing support is 1 and monostatic sensing support is 1, the bit combination indicates that the AP supports beacon passive sensing and may provide a beacon-based monostatic sensing result. It may be understood that, after the monostatic sensing support subfield is added, a sensing support field in the short sensing capabilities field indicates that any sensing mode other than passive sensing and monostatic sensing is supported.
In a second optional implementation, the first device is the PCP/AP, and the PCP/AP performs monostatic sensing based on the data frame, that is, the first frame structure is the data frame.
In an embodiment, in the DMG short sensing capability element field of the second frame structure, the PCP/AP may announce that the PCP/AP has the monostatic sensing capability. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a DMG beacon frame, an information request frame, an information response frame, a data frame, a probe request frame, a probe response frame, or the like. To be specific, optionally, the third information and the fourth information may be included in a short sensing capabilities field in the DMG short sensing capability element. For details, refer to the first optional implementation.
In another embodiment, at least one bit may be further used in an allocation field corresponding to an extended schedule element of a DMG beacon frame, to indicate that the allocation is used for/supports passive sensing and monostatic sensing. That is, the second frame structure is the DMG beacon frame.
In an embodiment, at least one bit may alternatively be added to the data frame to indicate that the PCP/AP supports passive sensing and monostatic sensing, or indicate that the PCP/AP has the passive sensing capability and the monostatic sensing capability. That is, the second frame structure is the data frame. For example, any at least one reserved bit in a PHY header or a MAC header may be used to carry the third information and the fourth information. It may be understood that the PCP/AP may also announce, by using the DMG short sensing capability element, that the PCP/AP supports passive sensing, and indicate, by using the one bit added to the data frame, that the PCP/AP supports monostatic sensing.
In a third optional implementation, the first device is the STA, and the STA performs monostatic sensing based on the SSW, the short SSW, or the BRP. In other words, the first frame structure is the SSW, the short SSW, or the BRP.
In the DMG short sensing capability element field of the second frame structure, the STA may announce that the STA has the monostatic sensing capability, or announce that the STA supports monostatic sensing. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, an information request frame, an information response frame, an SSW frame, a short SSW frame, a probe request frame, a probe response frame, or the like.
A structure of the DMG sensing short capabilities element field may have a structure shown in
Optionally, the STA may send the SSW or the short SSW in an A-BFT process, and may use a reserved bit in the SSW or the short SSW to indicate that the STA supports monostatic sensing, or indicate that the STA has the monostatic sensing capability.
In a fourth optional implementation, the first device is the STA, and the STA performs monostatic sensing based on the data frame, that is, the first frame structure is the data frame.
In an embodiment, in the DMG short sensing capability element field of the second frame structure, the STA may announce that the STA has the monostatic sensing capability. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, an information request frame, an information response frame, an SSW frame, a short SSW frame, a probe request frame, a probe response frame, a data frame, or the like. To be specific, optionally, the third information and the fourth information may be included in a short sensing capabilities field in the DMG short sensing capability element. For details, refer to the first optional implementation. It should be noted that, if the device is the STA, passive sensing support is 1, and monostatic sensing support is 1, the bit combination indicates that the STA supports passive sensing and may provide a monostatic sensing result.
Optionally, the STA may send the SSW frame or the short SSW frame in an A-BFT process, and may use a reserved bit in the SSW frame or the short SSW frame to indicate that the STA supports monostatic sensing, or indicate that the STA has the monostatic sensing capability.
In an embodiment, at least one bit may be added to the data frame to indicate that the STA supports passive sensing and monostatic sensing, or indicate that the STA has the passive sensing capability and the monostatic sensing capability. That is, the second frame structure is the data frame. For example, any at least one reserved bit in a PHY header or a MAC header may be used to carry the third information and the fourth information. It may be understood that the STA may also announce, by using the DMG short sensing capability element, that the STA supports passive sensing, and indicate, by using the one bit added to the data frame, that the STA supports monostatic sensing.
In some embodiments, the second device parses related information in the second frame structure, for example, the third information and the fourth information. The second device determines, by using the third information, that the first device supports monostatic sensing. The second device may request, by using the first information, the first device to perform monostatic sensing. The second device determines, by using the fourth information, that the first device supports passive sensing, and the second device may request the target beam information and the target location information from the first device by using the second information. It may be understood that, to help the second device parse the monostatic sensing result of the first device, the second device also needs to request the target beam information and the target location information from the first device.
For example, the first information and the second information may be included in an information request frame. For example, the first information and the second information are separately included in different elements of the information request frame, or the first information and the second information may be included in a passive sensing information element (for example, a DMG passive sensing beacon info element/DMG passive sensing SSW info element/DMG passive sensing short SSW info element/DMG passive sensing info element) of the information request frame, or the first information and the second information may be separately included in different request frames. For example, the second information is included in an information request frame, and the first information is included in another request frame (for example, a DMG sensing measurement setup request/DMG sensing measurement instance request/DMG sensing request). This is not limited in this application.
To be specific, optionally, the second device sends the information request frame to the first device, to request the target location information of the first device (including the information about the orientation posture for sending the first frame structure) and the target beam information (including information such as the horizontal beam direction, the vertical direction, the horizontal beam width, the vertical beam width, and the beam gain) for sending the first frame structure by the first device, to perform passive sensing based on the first frame structure subsequently sent by the first device. In addition, the second device may request the first device to perform monostatic sensing based on the first frame structure when the first device subsequently sends the first frame structure. After sensing is completed, the second device may request, from the first device, the first sensing result of monostatic sensing based on the first frame structure. It may be understood that the target location information of the first device and the target beam information for sending the first frame structure that are requested by the second device may also be used to interpret or parse the first sensing result.
For example, the first device is the AP or the PCP, the second device is the STA, and the first frame structure is a beacon. The STA may request, by using a DMG passive sensing beacon info element included in the information request frame, the AP to send information such as target beam information for the beacon and target location information of the AP. The AP sends the information response frame to the STA, where the information response frame includes a DMG passive sensing beacon info element (describing a sending time of the beacon, the location of the AP, and other information) and one or more DMG beacon sector descriptors elements (describing beam information for beacon sending and the like).
In embodiments of this application, the first information used to request the AP to perform monostatic sensing may be included in the DMG passive sensing beacon info element of the information request frame. In other words, the DMG passive sensing beacon info element additionally includes indication information (that is, the first information) to request the AP to perform monostatic sensing based on the beacon.
The STA requests, by using the information request frame, the target location information of the AP and related information of a target beam for sending the beacon, and requests, in the information request frame, the AP to perform monostatic sensing based on the beacon.
In this case, based on the target location information and the related information of the target beam for sending the beacon that are sent by the AP, the STA performs passive sensing by using the beacon sent by the AP, and the AP performs monostatic sensing based on the beacon at the request of the STA. Subsequently, the STA may request, from the AP, a beacon-based monostatic sensing result, that is, the first sensing result. The AP feeds back the first sensing result by using the first response frame. After receiving the first sensing result, the STA performs analysis in combination with a passive sensing result.
Optionally, the monostatic sensing request bit used to carry the first information may alternatively be included in a new element. In this case, the information request frame includes two elements. One element requests information related to passive sensing (that is, the DMG passive sensing beacon info element), and the other element requests monostatic sensing.
It should be noted that the requesting the target beam information and the target location information and the requesting the AP to perform monostatic sensing may be implemented separately by using two frames. To be specific, the information request/response is used to exchange the sending beam information for the beacon and the target location information of the AP, and the STA requests, by using another request frame (for example, the DMG sensing measurement setup request/DMG sensing measurement instance request/DMG sensing request), the AP to perform monostatic sensing based on the beacon. Correspondingly, the AP feeds back a monostatic sensing result based on a response frame corresponding to the another request frame. It may be understood that if the first frame structure is the BRP, the beacon in the foregoing interaction procedure may be replaced with the BRP.
Similarly, a monostatic sensing device is a STA, that is, the first device is the STA, and the second device is the AP or the PCP. A corresponding procedure may be used to complete interaction of related information request and feedback. It may be understood that when the monostatic sensing device is the STA, the information request/response frame includes a corresponding DMG passive sensing (SSW/Short SSW/BRP) info element. Correspondingly, information in the element is mainly used to describe information about the SSW/Short SSW/BRP sent by the STA in A-BFT. A monostatic sensing request bit may be added to the DMG passive sensing (SSW/Short SSW/BRP) info element to request the STA to perform monostatic sensing. The bit may be located in an (SSW/Short SSW/BRP) info control field. Alternatively, the information request frame may include the DMG passive sensing (SSW/Short SSW/BRP) info element and another element, and the another element includes the monostatic sensing request bit and is used to request the STA to perform monostatic sensing. Alternatively, the information request frame may be used to request the STA to send target beam information for the SSW/Short SSW/BRP and target location information of the STA, and the AP requests, by using another request frame (for example, a DMG sensing measurement setup request/DMG sensing measurement instance request/DMG sensing request), the STA to perform monostatic sensing based on (SSW/Short SSW/BRP).
It may be understood that if the PCP/AP or the STA performs monostatic sensing and passive sensing based on the data frame, the information request/response frame includes a corresponding DMG passive sensing (data PPDU) info element. Correspondingly, information in the element is mainly used to describe related information of a data frame data PPDU sent by the PCP/AP or the STA. For a specific interaction procedure, refer to descriptions in the foregoing embodiments. Details are not described herein again.
The target beam information for the first frame structure and the information about the target location of the first device for sending the first frame structure that are sent by the first device to the second device may be used to simultaneously interpret results of both passive sensing and monostatic sensing. This improves sensing efficiency, and reduces overheads for exchanging the location information and the beam sending information. In addition, simultaneous passive sensing and monostatic sensing based on a same beacon/SSW/Short SSW/data frame are implemented. In this way, sensing diversity gains at a same moment are increased. Compared with performance of independent sensing, sensing performance can be improved.
Optionally, the method may further include operation 305.
In some implementations, the first device sends the fifth information, where the fifth information is used to announce that the first device is to perform monostatic sensing based on the first frame structure, or the fifth information is used to announce that the first device is performing monostatic sensing based on the first frame structure. The first device may send the fifth information through broadcasting, multicasting, or unicasting. Correspondingly, the second device receives the fifth information.
For example, if the first device is the PCP or the AP, the first frame structure may be a DMG beacon frame in a current or next BTI, and the PCP or the AP announces, by using the fifth information, that the PCP or the AP is performing monostatic sensing based on the beacon in the current BTI, or the PCP or the AP announces, by using the fifth information, that the PCP or the AP is to perform monostatic sensing based on the beacon in the next BTI. After the corresponding BTI ends, the STA may request the first sensing result of monostatic sensing from the PCP or the AP. To parse the first sensing result, the STA may also request, from the PCP or the AP, target beam information for sending the beacon by the PCP or the AP and information about a target location of the PCP or the AP for sending the beacon in the process of monostatic sensing.
For example, if the first device is the PCP or the AP, the first frame structure may be a data frame in a current or next DTI, and the PCP or the AP announces, by using the fifth information, that the PCP or the AP is performing monostatic sensing based on the data frame in the current DTI, or the PCP or the AP announces, by using the fifth information, that the PCP or the AP is to perform monostatic sensing based on the data frame in the next DTI. After the corresponding DTI ends, the STA may request the first sensing result of monostatic sensing from the PCP or the AP. To parse the first sensing result, the STA may also request, from the PCP or the AP, target beam information for sending the data frame by the PCP or the AP and information about a target location of the PCP or the AP for sending the data frame in the process of monostatic sensing.
For example, if the first device is the PCP or the AP, the first frame structure may be a BRP in a current or next DTI, and the PCP or the AP announces, by using the fifth information, that the PCP or the AP is performing monostatic sensing based on the BRP in the current DTI, or the PCP or the AP announces, by using the fifth information, that the PCP or the AP is to perform monostatic sensing based on the BRP in the next DTI. After the corresponding A-BFT ends, the STA may request the first sensing result of monostatic sensing from the PCP or the AP. To parse the first sensing result, the STA may also request, from the PCP or the AP, target beam information for sending the BRP by the PCP or the AP and information about a target location of the PCP or the AP for sending the BRP in the process of monostatic sensing.
For example, if the first device is the STA, the first frame structure may be an SSW or a short SSW in current or next A-BFT, and the STA announces, by using the fifth information, that the STA is performing monostatic sensing based on the SSW/short SSW in the current A-BFT, or the STA announces, by using the fifth information, that the STA is to perform monostatic sensing based on the SSW/short SSW in the next A-BFT. After the corresponding A-BFT ends, the AP may request, from the STA, the first sensing result of monostatic sensing performed by the STA. To parse the first sensing result, the AP may also request, from the STA, target beam information for sending the SSW/Short SSW by the STA and information about a target location of the STA for sending the SSW/Short SSW in the process of monostatic sensing.
For example, if the first device is the STA, the first frame structure is a data frame in a current or next DTI, and the STA announces, by using the fifth information, that the STA is performing monostatic sensing based on the data frame in the current DTI, or the STA announces, by using the fifth information, that the STA is to perform monostatic sensing based on the SSW/short SSW in the next A-BFT. After the corresponding DTI ends, the AP may request, from the STA, the first sensing result of monostatic sensing performed by the STA. To parse the first sensing result, the AP may also request, from the STA, target beam information for sending the data frame by the STA and information about a target location of the STA for sending the data frame in the process of monostatic sensing.
For example, if the first device is the STA, the first frame structure is a BRP in a current or next DTI, and the STA announces, by using the fifth information, that the STA is performing monostatic sensing based on the BRP in the current DTI, or the STA announces, by using the fifth information, that the STA is to perform monostatic sensing based on the BRP in the next DTI. After the corresponding DTI ends, the AP may request, from the STA, the first sensing result of monostatic sensing performed by the STA. To parse the first sensing result, the AP may also request, from the STA, target beam information for sending the BRP by the STA and information about a target location of the STA for sending the data frame in the process of monostatic sensing.
The second device may request, by using the first request frame, to obtain the monostatic sensing result from the first device, and the first device sends the first sensing result of monostatic sensing to the second device by using the first response frame. Optionally, the first request frame is further used to request to obtain the target beam information and the target location information. For example, the first request frame may be an information request frame. Optionally, the first request frame may be used to request to obtain the monostatic sensing result, and the second device requests, by using the second request frame, to obtain the target beam information and the target location information. For example, the first request frame may be a DMG sensing poll frame, and the second request frame may be an information request frame. Further, the second device parses the first sensing result of the first device based on the obtained target beam information and the obtained target location information.
In some optional manners, the fifth information may be included in a third frame structure. If the first device is the PCP or the AP, the third frame structure is one or more of the following: an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a DMG beacon frame, an information request frame, an information response frame, a probe request frame, a probe response frame, a data frame, or the like. If the first device is the STA, the third frame structure is one or more of the following: an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, an information request frame, an information response frame, a probe request frame, a probe response frame, an SSW frame, a short SSW frame, a data frame, or the like.
For example, the fifth information may be included in a capability element field of the third frame structure, for example, included in a DMG short sensing capability element field.
Optionally, the fifth information may be included in a short sensing capabilities field in the DMG short sensing capability element.
In some optional implementations, as shown in

The memory is any storage medium that can be used to carry or store program code in a form of an instruction or a data structure and that can be read and/or written by a computer (for example, the communication apparatus shown in this application). However, this application is not limited thereto.
