For example, the access point may alternatively support one or more standards of the institute of electrical and electronics engineers (IEEE) 802.11 family, for example, 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, and 802.11ay.
The non-AP station may be a wireless communication chip, a wireless sensor, a wireless communication terminal, or the like, and may also be referred to as a user, user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile console, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The non-AP station may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having a wireless communication function, a computing device, another processing device connected to a wireless modem, a vehicle-mounted device, an internet of things device, a wearable device, a terminal device in a 5G network, a terminal device in a future 6G network, a terminal device in a PLMN, or the like. This is not limited in embodiments of this application. The non-AP station may be a device that supports a WLAN standard. For example, the non-AP station may support one or more standards of the IEEE 802.11 family, for example, 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, and 802.11ay.

The transmitter and the receiver are respectively configured to send a package structure and receive a packet structure. The memory is configured to store signaling information, store a preset value agreed in advance, and the like. The processor is configured to parse the signaling information, process related data, and the like.
Radar sensing is a wireless sensing technology. A radar includes a transmit antenna and a receive antenna. The transmit antenna sends an electromagnetic wave. The electromagnetic wave is reflected when reaching a target, and a reflected wave may be received by the receive antenna. Based on changes of a transmitted wave and a received wave, the radar system analyzes feature information of the target, such as a location, a shape, a motion characteristic, and a motion track, through signal processing. The radar sensing has many unique advantages. For example, a radar is not affected by light, and has a capability of penetrating an obstacle, so that personal privacy can be better protected, and a radar is capable of sensing a far range, and does not cause harm to people or animals. An advantage of implementing sensing by using the radar technology is mainly reflected in motion detection. A motion status of the target, for example, a motion direction and a motion speed, is observed and interpreted based on a doppler effect of an echo of the target.
An introduction of the sensing technology in the WLAN has a good commercial prospect. The wireless sensing (Wi-Fi sensing) technology may be applied in different scenarios. For example, in sports, this technology may be used to detect motion statuses and motion tracks of a person and a ball. For another example, in a home environment, this technology may be used to perform human body fall detection, to prevent an elderly person from falling. The wireless sensing technology may make full use of existing WLAN resources without a need of high costs. In a future densely deployed WLAN, there are a plurality of non-AP STAs in a coverage area of one AP, and the AP may perform proper resource scheduling on each non-AP STA to improve throughput and robustness of a system, and the like.
The 802.11bf protocol supports sensing on the sub-7 GHz frequency band and a high frequency band (for example, 60 GHz). On the sub-7 GHz frequency band, the sensing is used to: identify actions, track motion tracks, and detect falling by detecting wireless channels and estimate channel state information (CSI). On the 60 GHz frequency band, the sensing is used to obtain environment information and state information of the target by performing directional beam scanning on an environment to obtain a range doppler map (RD Map). A phase of the transmit antenna is adjusted, so that energy of radio signals is aggregated in a direction, to form a directed (or directional) beam. A directional beam has a narrower beam width and more concentrated energy. Therefore, the directional beam has a higher antenna gain and interference to another received signal is reduced.
The following briefly describes some concepts of a sensing procedure.
A WLAN sensing technology may include the following roles. It should be understood that in some scenarios, the following different roles may be performed by a same device.
In SBP, roles in sensing further include:
The sensing procedure may be used to describe how to perform sensing, and the sensing procedure may include the following five operations.
In the IEEE 802.11bf protocol, one sensing session is initiated by one sensing initiator (sensing initiator) and participated by one or more sensing responders. In the protocol, five types of high-frequency sensing are specified: monostatic sensing, bistatic sensing, multistatic sensing, monostatic with coordination sensing, and bistatic with coordination sensing.
It can be seen from
The sensing by proxy means that a first station (for example, a non-AP STA) may request a second station (for example, an AP) to perform WLAN sensing and request the second station to feed back a sensing result to the first station. The station that initiates an SBP procedure (the first station) is referred to as an SBP initiator, and the requested station (the second station) participates in the SBP as a proxy. The requested station is referred to as an SBP responder (SBP responder), and the requested station is also a sensing initiator in the SBP sensing procedure. One or more parties participating in the sensing procedure initiated by the SBP responder are sensing responders.
Corresponding to the five types of high-frequency sensing shown in
It can be seen from
S101: An SBP initiator sends an SBP request frame to an SBP responder, where the frame includes a configuration parameter of the SBP procedure.
S102: After the SBP request frame is received, the SBP responder may reply with an SBP response frame.
If the configuration parameter in the SBP request frame complies with setting of the SBP responder, the SBP response frame indicates that an SBP request is accepted and SBP is successfully established, otherwise, an SBP request is rejected and the SBP fails to be established.
S101 and S102 may be referred to as an SBP setup phase. After the SBP is successfully established, the SBP responder, as a sensing initiator, initiates a sensing procedure to one or more sensing responders. The sensing procedure includes a sensing measurement setup phase and a sensing measurement instance phase. The sensing measurement setup phase includes S103 and S104.
S103: The SBP responder sends a sensing measurement setup request (sensing measurement setup request) frame to the sensing responder.
The sensing measurement setup request frame includes a sensing measurement setup identifier (sensing measurement setup ID) and one or more sensing measurement setup parameters elements.
S104: The sensing responder sends a sensing measurement setup response frame to the SBP responder.
The sensing measurement setup response frame includes a status code in response to a sensing measurement setup request and/or the one or more sensing measurement setup parameters elements.
S105: The sensing responder and the SBP responder perform a sensing measurement.
The sensing measurement performed on the sub-7 GHz frequency band is a trigger-based (TB) sensing measurement. The sensing measurement includes that one of the sensing responder and the SBP responder sends a sensing PPDU and the other obtains a sensing measurement result. If the sensing responder obtains the sensing measurement result as a sensing receiver, the sensing responder may send the sensing measurement result to the SBP responder.
S106: After obtaining the sensing measurement result, the SBP responder feeds back the sensing measurement result to the SBP initiator by using an SBP report frame.
S106 is an SBP reporting (SBP reporting) phase. S107 and S108 are an SBP termination phase. The SBP may be terminated by either the SBP initiator or the SBP responder by sending an SBP termination frame.
S107: The SBP initiator sends the SBP Termination frame to terminate the SBP procedure.
S108: The SBP responder sends the SBP Termination frame to terminate the SBP procedure.
The SBP procedure shown in
In view of this, this application provides a sensing method and a communication apparatus. An SBP responder may determine, based on a result of a sensing measurement setup of a sensing responder, whether to accept an SBP request, and accept the SBP request when the result of the sensing measurement setup is successful, to increase a success rate of an SBP setup, thereby improving sensing efficiency.
In this application, a message may be understood as a frame, and information or a parameter in the message may be understood as a field in the frame, that is, the information or the parameter in the message is indicated by the field in the frame. In addition, the field in this application is a field in a broad sense. In some cases, the field may also be referred to as a domain, an element, a subelement, a subfield, or the like.
S210: A sensing responder sends a first message to an SBP responder, and correspondingly, the SBP responder receives the first message from the sensing responder.
The first message includes information about whether the sensing responder accepts a first sensing measurement setup. That the first message includes the information about whether the sensing responder accepts the first sensing measurement setup may also be understood as that the first message includes first indication information, where the first indication information indicates whether the sensing responder accepts the first sensing measurement setup.
For example, the first indication information may be a status code.
The information about whether the sensing responder accepts the first sensing measurement setup may also be referred to as information about whether a request for the first sensing measurement setup is successful, or referred to as a result of the first sensing measurement setup.
For example, the first message may be a measurement setup response frame, and the information about whether the sensing responder accepts the first sensing measurement setup may be a status code field in the measurement setup response frame.
Optionally, the first message may further include an identifier of the first sensing measurement setup. For example, the identifier of the first sensing measurement setup is a sensing measurement setup ID.
S220: The SBP responder sends a second message to an SBP initiator, and correspondingly, the SBP initiator receives the second message from the SBP responder.
The second message includes information about whether first SBP is successfully established. That the second message includes the information about whether the first SBP is successfully established may also be understood as that the second message includes second indication information, where the second indication information indicates whether the first SBP is successfully established.
For example, the second indication information may be a status code.
The information about whether the first SBP is successfully established may also be referred to as information about whether the SBP responder accepts a request of establishing the first SBP, or referred to as a result of establishing the first SBP.
For example, the second message may be an SBP response frame, and the information about whether the first SBP is successfully established may be a status code field in the SBP response frame.
Optionally, the second message may further include an identifier of the first SBP. For example, the identifier of the first SBP may be a value of a dialog token, where the dialog token may be used to mark an SBP request, and the value of the dialog token may be the same as a value of a dialog token that is set by the SBP initiator in an SBP request frame.
The second message is determined based on the first message. In other words, the second message is determined via the first message. In other words, the SBP responder determines, based on whether the sensing responder accepts the first sensing measurement setup, whether the first SBP is successfully established.
For example, if the first message includes information about that the sensing responder accepts the first sensing measurement setup, the second message includes information about that the first SBP is successfully established. For another example, if the first message includes information about that the sensing responder rejects the first sensing measurement setup, the second message includes information about that the first SBP fails to be established.
Optionally, an operation in S210 may be performed by a plurality of sensing responders. In other words, the plurality of sensing responders may send the first message to a same SBP responder. In this case, that the second message is determined based on the first message may be understood as that the SBP responder determines, based on whether the plurality of sensing responders accept the first sensing measurement setup, whether the first SBP is successfully established. For example, when X sensing responders in the plurality of sensing responders accept the first sensing measurement setup, the SBP responder determines that the first SBP is successfully established, where X may be a preset value.
For example, the preset value may be indicated by the SBP initiator to the SBP responder before S210, or may be predefined in a protocol.
Optionally, in this application, the sensing responder may be an AP, or may be a non-AP STA. Similarly, the SBP responder may be an AP, or may be a non-AP STA. The SBP initiator may be an AP, or may be a non-AP STA. Whether the SBP initiator, the SBP responder, and the sensing responder are APs or non-AP STAs depends on a sensing type, and reference may be made to
Based on the foregoing solution, the SBP responder may determine, based on a result of a sensing measurement setup, whether SBP is established. When the result of the sensing measurement setup is successful, the SBP responder sends information about that the SBP is successfully established. When the result of the sensing measurement setup is unsuccessful, the SBP responder sends information about that the SBP fails to be established. In this way, this can increase a success rate of the SBP setup, and further improve sensing efficiency.
Optionally, before S210, the method 200 further includes: S230: The SBP initiator sends a third message to the SBP responder, and correspondingly, the SBP responder receives the third message from the SBP initiator.
The third message is used to request to establish the first SBP, that is, the third message is used to initiate a setup of the first SBP.
The third message includes a configuration parameter of the first sensing measurement setup. In other words, the third message includes a parameter used to configure the sensing measurement setup in the SBP. In other words, the third message includes parameters of sensing of different sensing types, and the sensing type may be any one shown in
In addition, the configuration parameter of the sensing measurement setup may include one or more of the following parameters: a parameter required in a sensing measurement setup procedure, a parameter required in a sensing measurement procedure, a parameter fed back after the sensing measurement is completed, or the like.
For example, the third message may be an SBP request frame, and the second message may be considered as a response to the third message.
Based on the foregoing solution, the SBP initiator may request, in the third message, the configuration parameter of the sensing measurement setup. Further, the SBP responder may determine, based on the configuration parameter, a parameter for performing the sensing measurement setup with the sensing responder. In this way, the SBP initiator can control and manage an SBP procedure more flexibly and comprehensively.
Optionally, the third message may further include the identifier of the first SBP. For example, the identifier of the first SBP may be a value of a dialog token, and the dialog token may be used to mark an SBP request initiated this time.
Optionally, the third message may further include the identifier of the first sensing measurement setup. In other words, the identifier of the first sensing measurement setup may be determined by the SBP initiator. In this case, the SBP initiator may include the identifier of the first sensing measurement setup in the third message, and the SBP responder includes the identifier of the first sensing measurement setup in the second message.
Optionally, the identifier of the first sensing measurement setup is determined by the SBP responder. In this case, the third message of the SBP initiator may not carry the identifier of the sensing measurement setup, and after determining the identifier of the first sensing measurement setup, the SBP responder includes the identifier of the first sensing measurement setup in the second message.
Based on the foregoing solution, the identifier of the sensing measurement setup may be determined by the SBP initiator, or may be determined by the SBP responder. In this way, flexibility of the SBP procedure can be improved.
Optionally, after S230 and before S210, the method 200 further includes: S240: The SBP responder sends a fourth message to the sensing responder, and correspondingly, the sensing responder receives the fourth message from the SBP responder.
The fourth message is used to request to initiate the first sensing measurement setup.
The fourth message is determined based on the third message, in other words, the fourth message includes partial information in the third message. For example, the third message includes that a sensing responder #1 is a sensing receiver, and in this case, the SBP responder may configure the sensing responder #1 as the sensing receiver based on the fourth message. For another example, the third message includes that a number of sensing responders is five, and in this case, the SBP responder may initiate sensing measurement setups with the five sensing responders based on the fourth message.
For example, the fourth message may be a measurement setup request frame, and the first message may be considered as a response to the fourth message.
Based on the foregoing solution, the SBP responder may determine, based on the configuration parameter sent by the SBP initiator, the parameter for performing the sensing measurement setup with the sensing responder. In this way, the SBP initiator can control and manage the SBP procedure more flexibly and comprehensively.
Optionally, if the first SBP fails to be established, the second message may further include a recommended parameter for the first sensing measurement setup. The recommended parameter may be understood as a parameter acceptable to the SBP responder for the first SBP. For example, the SBP request frame indicates that a number of sensing responders is 5, the SBP responder can perform sensing measurement setups with only three sensing responders in a subsequent sensing measurement setup phase, and the SBP responder may indicate, in the second message, that the SBP fails to be established, or may include information to indicate that a recommended number of sensing responders is 3.
It should be understood that, in the method 200 in this application, the SBP initiator and the SBP responder may be devices used for WLAN high-frequency sensing, and may be respectively referred to as a DMG SBP initiator and a DMG SBP responder. Similarly, the SBP request frame and the SBP response frame are frames used for the WLAN high-frequency sensing, and may also be referred to as a DMG SBP Request frame and a DMG SBP Response frame. Optionally, the method 200 in this application may also be applied to a sub-7 GHz frequency band. This is not limited. For ease of description, the following uses the DMG SBP initiator, the DMG SBP responder, the DMG SBP Request frame, and the DMG SBP Response frame as examples for description.
The following describes in detail a configuration parameter of the DMG SBP Request frame provided in this application. The configuration parameter may include at least one of an SBP-specific parameter and a DMG sensing-common parameter. The SBP-specific parameter may be placed in a DMG SBP parameters element, and the DMG sensing-common parameter may be indicated by reusing an existing DMG sensing measurement setup element in DMG sensing. The SBP-specific parameter includes at least one parameter in the DMG SBP parameters element, and the DMG sensing-common parameter includes at least one parameter in the DMG sensing measurement setup element.
In one embodiment, the DMG SBP Request frame is an action frame, and is sent by the DMG SBP initiator to the DMG SBP responder. An action field of the DMG SBP Request frame may include at least one field shown in Table 1.
For example, the “configuration parameter of the first sensing measurement setup” in S230 may include at least one field of the DMG SBP parameters element and/or information carried in at least one field of the DMG sensing measurement setup element.
It should be understood that, in Table 4, an order of the DMG TX-RX pair 1 to the DMG TX-RX pair Q in the DMG TX-RX pair subelement may indicate a sensing measurement order of pairs. In other words, a sensing measurement may be sequentially performed on the DMG TX-RX pair 1, a DMG TX-RX pair 2, . . . , and the DMG TX-RX pair Q.
The sensing type field is used in the DMG SBP Request frame to indicate a sensing type of sensing performed in a DMG SBP Request process. This field occupies 3 bits. Values 0 to 3 are defined, and values 4 to 7 are reserved bits. Table 6 describes a meaning of the sensing type field.
There is no indication of a monostatic type. However, in the SBP, the DMG SBP initiator may request to perform monostatic SBP. Therefore, this objective may be achieved in two manners:
One manner is to use the monostatic field in Table 2, and the other manner is to use the value 4 to indicate the monostatic type in Table 6.
In the foregoing example of the DMG SBP Request frame, the sensing type field may indicate the sensing type of sensing performed in the DMG SBP Request process. In addition, the monostatic type may be indicated by the monostatic field in Table 2 in addition to being indicated by the value in Table 6. In other words, the sensing type field or the monostatic field may carry seventh information, and the seventh information indicates that the type of the SBP is the monostatic type. In addition, the sensing type field may further carry first information or fourth information, where the first information indicates that the type of the SBP is a bistatic with coordination type, and the fourth information indicates that the type of the SBP is a monostatic with coordination type.
For a bistatic with coordination SBP type, for example, as shown in
Based on the foregoing solution, the DMG SBP Request frame may indicate the information about the sensing responder used as the sensing transmitter and the information about the sensing responder used as the sensing receiver, so that sensing between sensing responders in the bistatic with coordination sensing type can be implemented, and sensing efficiency can be improved.
In addition, for the bistatic with coordination SBP type, in Table 2, the DMG TX-RX pair subelement is used to indicate a sending direction of a sensing PPDU between sensing responders.
In other words, the DMG TX-RX pair subelement is used to indicate a correspondence between the first sensing responder and the second sensing responder. Based on the DMG TX-RX pair subelement, the DMG SBP responder may learn a sensing responder that is used as the RX and that corresponds to a sensing responder used as the TX. For example, the DMG TX-RX pair 1 field in the DMG TX-RX pair subelement is A and B. Therefore, the DMG SBP responder may learn that A is the RX and B is the TX, that is, the sending direction of the sensing PPDU between the sensing responders is from B to A. In this application, information carried in the DMG TX-RX pair subelement may be referred to as third information.
Based on the foregoing solution, the DMG SBP Request frame may indicate the sending direction of the sensing PPDU between the sensing responders, so that the sensing between the sensing responders in the bistatic with coordination sensing type can be implemented, and sensing efficiency can be improved.
For the monostatic with coordination type, the sequential sounding field in Table 2 may be used to indicate a plurality of sensing responders to perform sensing measurements simultaneously or in sequence, and the sensing initiator monostatic requested field in Table 3 may be used to indicate the DMG SBP responder whether to participate in the monostatic sensing as a sensing responder. Information carried in the sequential sounding field may be referred to as fifth information, and information carried in the sensing initiator monostatic requested field may be referred to as sixth information.
For any one of the foregoing sensing types, the DMG SBP report control field in Table 2 is used to set a parameter related to a feedback of a sensing result, and information carried in the DMG SBP report control field may be referred to as eighth information. In one embodiment, as shown in Table 5, the eighth information may include at least one of the following: feeding back after each measurement ends or feeding back after a plurality of measurements end, feeding back a sensing measurement result of one sensing responder each time or feeding back sensing measurement results of a plurality of sensing responders each time, feeding back whether a report includes location configuration information of the sensing responder, feeding back whether the report includes an antenna orientation of the sensing responder, and feeding back whether the report includes a time when the sensing measurement occurs, where each item may be carried in a field in Table 5.
Based on the foregoing solution, the DMG SBP initiator requests the parameter related to the feedback of the sensing result, so that the DMG SBP initiator can manage content and a feedback manner of a DMG SBP Report frame, to improve flexibility of feeding back the sensing result and improve sensing efficiency.
Optionally, when the SBP responder sends the fourth message to the sensing responder, the fourth message may include the DMG sensing measurement setup element, and the DMG sensing measurement setup element is used to configure a measurement setup parameter for the sensing responder. To support a sensing measurement performed between sensing responders (TX-RX or R2R mentioned above) in the bistatic with coordination type, a field may be added to the DMG sensing measurement setup element shown in
Optionally, the SBP initiator may request a plurality of types of sensing in one SBP request. In other words, different types of SBP shown in
In addition, in the foregoing case, if a DMG sensing measurement setup identifier is determined by the DMG SBP initiator, the DMG sensing measurement setup identifier field in Table 1 may be set to a reserved value, and further, the DMG sensing measurement setup identifier may be carried by the DMG sensing measurement setup element in the DMG SBP Request frame. In one embodiment, an implementation in which the sensing measurement setup element carries the DMG sensing measurement setup identifier may be as follows: To identify each sensing measurement, each DMG sensing measurement setup element may include a DMG sensing measurement setup identifier (DMG sensing measurement setup ID) field, where the DMG sensing measurement setup identifier field is used to indicate the DMG sensing measurement setup identifier. For example, a length of the DMG sensing measurement setup identifier field may be one octet, and a location of the DMG sensing measurement setup identifier field may be located between the element identifier extension field and the measurement setup control field shown in
Optionally, when the DMG SBP Request frame may include a plurality of DMG sensing measurement setup elements, the DMG SBP Request frame may also include a plurality of DMG SBP parameters elements. The plurality of DMG sensing measurement setup elements may one-to-one correspond to the plurality of DMG SBP parameters elements, and one DMG sensing measurement setup element and one DMG SBP parameters element correspond to one sensing measurement.
As an example, when a plurality of sensing types are requested, that the SBP is successfully established indicates that all requested types of sensing measurements are successfully established, and that the SBP fails to be established may indicate that not all requested types of sensing measurements can be established. In addition, the DMG SBP Response frame may indicate types in which sensing measurements are successfully established, and the DMG SBP initiator may further determine whether to resend a DMG SBP Request frame to carry the sensing types in which sensing measurements can be successfully established.
Optionally, the DMG SBP initiator may request a type of a measurement report by using the report type field in the DMG sensing measurement setup element, and the DMG SBP responder may request, based on a request of the field, another sensing responder to feed back a measurement report of this type. For example, as shown in
Optionally, the DMG sensing measurement setup element further includes a DMG sensing scheduling subelement, where the DMG sensing scheduling subelement is used to set an occurrence time, a frequency, a period, a quantity of times of measurements, and the like. For example, the DMG SBP initiator may use the DMG sensing scheduling subelement to request to start a burst, and the DMG SBP responder may set to perform a sensing measurement with another sensing responder based on the time. The DMG sensing scheduling subelement may include at least one field shown in Table 7. A meaning of each field is also shown in Table 7. In Table 7, a unit of a field length is an octet.
The following describes in detail a recommended parameter of the DMG SBP Response frame provided in this application. The recommended parameter may include at least one of an SBP-specific parameter and a DMG sensing-common parameter. The SBP-specific parameter may be placed in the DMG SBP parameters element, and the DMG sensing-common parameter may be indicated by reusing the existing DMG sensing measurement setup element in DMG sensing. The SBP-specific parameter includes at least one parameter in the DMG SBP parameters element, and the DMG sensing-common parameter includes at least one parameter in the DMG sensing measurement setup element.
In one embodiment, the DMG SBP Response frame is also an action frame, and is sent by the DMG SBP responder to the DMG SBP initiator. An action field of the DMG SBP Response frame may include at least one field shown in Table 8.
It should be understood that for the DMG SBP parameters element, fields included in the DMG sensing measurement setup element, and content carried in each field in the DMG SBP Response frame, refer to the DMG SBP parameters element and the DMG sensing measurement setup element in the DMG SBP Request frame. Details are not described herein again. These fields included in the DMG SBP Request frame indicate configuration parameters requested by the DMG SBP initiator. These fields included in the DMG SBP Response frame indicate recommended parameters from the DMG SBP responder. For example, a configuration related to the SBP report control field in the DMG SBP Request frame means a configuration from the DMG SBP responder requested by the DMG SBP initiator, that is, how the DMG SBP responder needs to feed back a report to the DMG SBP initiator. A setting related to the SBP report control field in the DMG SBP Response frame means a configuration expected by the DMG SBP responder, that is, how the DMG SBP responder expects to feed back a report to the DMG SBP initiator.
It should be further understood that, if the DMG sensing measurement setup identifier is determined by the DMG SBP responder, the DMG sensing measurement setup identifier field in Table 8 may be set to a reserved value, and further, the DMG sensing measurement setup identifier may be carried by the DMG sensing measurement setup element in the DMG SBP Response frame. A manner in which the sensing measurement setup element carries the DMG sensing measurement setup identifier may be as follows: To identify each sensing measurement, each DMG sensing measurement setup element may include a DMG sensing measurement setup identifier field, where the DMG sensing measurement setup identifier field is used to indicate the DMG sensing measurement setup identifier. For example, a length of the DMG sensing measurement setup identifier field may be one octet, and a location of the DMG sensing measurement setup identifier field may be located between the element identifier extension field and the measurement setup control field shown in
In addition, if the DMG sensing measurement setup identifier is determined by the DMG SBP responder, the DMG sensing measurement setup identifier field in the DMG SBP Request frame may be set to a reserved value. If the DMG sensing measurement setup identifier is determined by the DMG SBP initiator, the DMG sensing measurement setup identifier field in the DMG SBP Response frame may be set to a reserved value or reuse a value of the DMG sensing measurement setup identifier field in the DMG SBP Request frame.
Based on the foregoing solution, if the first SBP fails to be established, the second message may further include the recommended parameter for the first sensing measurement setup. In this way, the DMG SBP initiator may re-initiate a DMG SBP Request based on the recommended parameter in the DMG SBP Response frame, to increase a success rate of the SBP setup can be improved, thereby improving sensing efficiency.
S310: An SBP responder generates a fifth message.
The fifth message is used to report a sensing measurement result of a sensing responder, that is, the fifth message carries a sensing measurement report of the sensing responder, that is, the fifth message carries an SBP report.
In an example, the fifth message may be an SBP report (frame.
Optionally, the fifth message includes an identifier of first SBP. For example, the identifier of the first SBP may be a value of a dialog token, where the dialog token may be used to mark an SBP request, and the value of the dialog token may be the same as a value of a dialog token that is set by an SBP initiator in an SBP request frame.
If the SBP responder is a sensing transmitter or the SBP responder is not the sensing responder, the SBP responder may receive the sensing measurement result from a sensing receiver. If the SBP responder is a sensing receiver, the SBP responder may obtain the sensing measurement result based on a received sensing PPDU.
S320: The SBP responder sends the fifth message to the SBP initiator, and correspondingly, the SBP initiator receives the fifth message from the SBP responder.
A feedback manner of the SBP report frame and a parameter carried in the SBP report frame should be consistent with those requested by the SBP initiator, or should be consistent with a result negotiated by the SBP initiator and the SBP responder.
Optionally, the fifth message may be determined based on the eighth information in the method 200. In other words, the SBP responder feeds back the responded sensing measurement result to the SBP initiator based on the request of the SBP initiator, and the sensing measurement result is a result related to the sensing responder. For example, if the eighth information indicates to feed back a report including location configuration information of the sensing responder, the SBP responder may request the location configuration information of the sensing responder from the sensing responder, so that the SBP responder may obtain the location configuration information of the sensing responder from the sensing responder and feed back the corresponding location configuration information to the SBP initiator.
As an example, the SBP report frame is fed back in the following two manners.
Manner 1: The SBP responder feeds back a measurement result of a single sensing responder.
For example, the SBP responder may send the SBP report frame to the SBP initiator after obtaining a sensing measurement result of any sensing responder.
Optionally, in Manner 1, before S310, the SBP initiator may send the eighth information to the SBP responder, where the eighth information includes an indication for feeding back a sensing measurement result of one sensing responder each time. For details, refer to the method 200.
Manner 2: The DMG SBP responder feeds back measurement results of a plurality of sensing responders.
For example, the SBP responder may send the SBP report frame to the SBP initiator after obtaining the sensing measurement results of the plurality of sensing responders.
For example, in Manner 2, the SBP responder may perform feedback by using an aggregated MAC protocol data unit (A-MPDU).
Optionally, in Manner 2, before S310, the SBP initiator may send the eighth information to the SBP responder, where the eighth information includes an indication for feeding back sensing measurement results of a plurality of sensing responders each time. For details, refer to the method 200.
It should be understood that the parameter carried in the SBP report frame is unrelated to a feedback manner.
Based on the foregoing solution, the SBP responder may report the sensing measurement result to the SBP initiator in different manners, to improve flexibility of feeding back the sensing result, thereby improving sensing efficiency.
It should be understood that, in the method 300 in this application, the SBP initiator and the SBP responder may be devices used for WLAN high-frequency sensing, and may be respectively referred to as a DMG SBP initiator and a DMG SBP responder. Similarly, the SBP report frame is a frame used for the WLAN high-frequency sensing, and may also be referred to as a DMG SBP Report frame. Optionally, the method 300 in this application may also be applied to a sub-7 GHz frequency band. This is not limited. For ease of description, the following uses the DMG SBP initiator, the DMG SBP responder, and the DMG SBP Report frame as examples for description.
The DMG SBP Report frame may include at least one field shown in Table 9.
Optionally, when sending the DMG SBP Report frame, the DMG SBP responder may include, based on a request of a DMG SBP Request frame, one or more of location configuration information (LCI), a MAC address or an identifier (for example, an AID or a USID), an antenna orientation, a corresponding measurement occurrence timestamp, and the like of a corresponding sensing responder. The information may be carried in the DMG sensing report control element and the DMG sensing report element.
Optionally, the fifth message may include ninth information, and the ninth information indicates a sensing transmitter and a sensing receiver corresponding to the sensing measurement result.
In one embodiment, for a sensing measurement performed between sensing responders in a bistatic with coordination sensing type, the DMG SBP Report frame may indicate a TX-RX pair corresponding to the report.
In an implementation, an ID of TX and an ID of RX, that is, a TX sensing responder ID and an RX sensing responder ID, may be used, and the two IDs may be placed in the DMG sensing report control field. For example, still as shown in
It should be understood that the LCI may be carried in the DMG sensing report element, or may be carried in the TX sensing responder information field, or may be carried in the RX sensing responder information field. This is not limited in this application.
Based on the foregoing solution, for the sensing measurement between the sensing responders, the SBP responder may report a measurement result of R2R (that is, between a sensing responder used as a sensing transmitter and a sensing responder used as a sensing receiver) to the SBP initiator. In this way, an error rate of a DMG SBP report can be reduced, and sensing efficiency can be improved.
Manner 1: An SBP responder and an SBP initiator terminate first SBP by using a timer.
S410-a: The SBP responder starts a first timer, and sets start duration of the first timer to first duration. Correspondingly, the SBP initiator may start a second timer, and set start duration of the second timer to the first duration.
For example, the first duration may be preset duration. In an implementation, before S410, the SBP initiator indicates the first duration to the SBP responder. For example, the SBP request frame in the method 200 may carry tenth information, the tenth information indicates the first duration, and the tenth information may be carried in a DMG SBP expiry exponent field. As shown in Table 3, there is a correspondence between the DMG SBP expiry exponent and the first duration, and the first duration may be determined based on the DMG SBP expiry exponent. In another implementation, the first duration may be predefined in a protocol.
The SBP responder may start the first timer in any one of the following cases: for example, start the first timer after a second message is sent, or after an acknowledgment (ACK) of the second message is received, or after a first SBP report frame is sent. Similarly, the SBP initiator may start the second timer in any one of the following cases: for example, may start the second timer after the second message is received, or after the ACK of the second message is sent, or after a first SBP report frame is received.
It should be understood that, in the method 400, the second message indicates that the first SBP is successfully established.
S420-a: The SBP responder terminates the first SBP when the first timer expires. Correspondingly, the SBP initiator may terminate the first SBP when the second timer SBP expires.
It should be understood that the timer expires may be understood as that the timer runs out or the timer returns to zero.
Optionally, when the SBP responder interacts with the SBP initiator by using the sensing measurement result, and when the SBP responder and the sensing responder perform a sensing measurement, the first timer and the second timer may be paused.
In one embodiment, the DMG SBP initiator and the DMG SBP responder each set a countdown clock. The DMG SBP initiator starts timing when receiving a DMG SBP Response frame carrying a status code=SUCCESS, and the DMG SBP responder starts timing when receiving an Ack (corresponding to the DMG SBP Response frame, and indicating that the DMG SBP initiator receives the DMG SBP Response frame), that is, starts timing when DMG SBP is successfully established. When a sensing measurement occurs or a result is fed back, the timing is paused. Otherwise, the timing continues. When the timing returns to zero, the DMG SBP is terminated. Countdown times each are the first duration, may be exchanged in a DMG SBP setup phase, and may be indicated by the DMG SBP expiry exponent field.
Based on the foregoing solution, the SBP responder and the SBP initiator may terminate the first SBP by using the timer, reduce an SBP termination procedure, thereby reducing signaling overheads.
Manner 2: An SBP responder and an SBP initiator terminate first SBP by using an SBP Termination frame.
S410-b: The SBP responder sends a sixth message to the SBP initiator, where the sixth message is used to terminate the first SBP.
S420-b: The SBP initiator sends a seventh message to the SBP responder, where the seventh message is used to terminate the first SBP.
For example, the sixth message and the seventh message may be SBP termination frames.
Optionally, the sixth message or the seventh information includes eleventh information, and the eleventh information indicates to terminate all SBP of a bistatic with coordination type, or indicate to terminate all SBP of a monostatic type.
It should be understood that, in the method 400 in this application, the SBP initiator and the SBP responder may be devices used for WLAN high-frequency sensing, and may be respectively referred to as a DMG SBP initiator and a DMG SBP responder. Similarly, the SBP Termination frame is a frame used for the WLAN high-frequency sensing, and may also be referred to as a DMG SBP Termination frame. Optionally, the method 400 in this application may also be applied to a sub-7 GHz frequency band. This is not limited. For ease of description, the following uses the DMG SBP initiator, the DMG SBP responder, and the DMG SBP Termination frame as examples for description.
In one embodiment, the DMG SBP initiator or the DMG SBP responder sends the DMG SBP Termination frame, and performs termination on the DMG SBP sensing based on a sensing type. The SBP Termination frame may include at least one field shown in Table 10.
The DMG SBP termination control field may include at least one of the following: a terminate all coordinated monostatic setups field, a terminate all bistatic setups field, a terminate all multistatic setups field, a DMG SBP setup unsuccess field, and a reserved field. However, currently, there is a lack of termination indication for two sensing types. Therefore, in this application, the DMG SBP termination control field may further include at least one of a terminate all coordinated bistatic setups field and a terminate all monostatic setups field. Each of the two fields occupies one bit, one is used to indicate whether to terminate all bistatic with coordination setups, and the other is used to indicate whether to terminate all monostatic setups.
Manner 3: A last report is used to indicate to terminate SBP.
In one embodiment, one bit may be used in a DMG SBP Report frame to indicate the last report, that is, a last SBP report. After receiving an indication of the last report, the DMG SBP initiator automatically terminates DMG SBP, and after sending the indication of the last report, the DMG SBP responder automatically terminates the DMG SBP. For content and a format of the DMG SBP Report frame, refer to the method 300.
It should be understood that Manner 1 to Manner 3 in the method 300 may be separately implemented, or may be combined with each other in some scenarios. This is not limited in this application.
It should be further understood that the method 200, the method 300, and the method 400 may be separately implemented, or may be combined with each other. This is not limited.
In addition, the frame format, the field name, the field length, and the like in this application are merely examples for description. The frame format, the field name, the field length, and the like may alternatively be other formats provided that corresponding information can be carried or indicated. A format is not limited in this application. For example, the DMG SBP expiry exponent field in Table 3 is 4 bits. However, the length of the field may also be another value, for example, 2 bits or 8 bits. In addition, in this application, fields in any table are not mandatory. In some cases, the message provided in this application may include only a part of the fields provided in this specification. Similarly, the fields shown in
S501: A DMG SBP initiator sends a DMG SBP Request frame (an example of a third message) to a DMG SBP responder, where the frame includes a configuration parameter related to a DMG SBP procedure. For details about the configuration parameter, refer to Table 1 to Table 8.
S502: After the DMG SBP Request frame is received, the DMG SBP responder sends a DMG sensing measurement setup request frame (an example of a fourth message) to one or more sensing responders.
The DMG sensing measurement setup request frame includes a sensing measurement setup identifier and one or more sensing measurement setup parameters elements.
S503: The one or more sensing responders send a DMG sensing measurement setup response frame (an example of a first message) to the DMG SBP responder.
Each DMG sensing measurement setup response frame includes a status code in response to a sensing measurement setup request, to indicate whether a sensing measurement setup corresponding to this sensing responder is successful. The DMG sensing measurement setup response frame may further include the one or more sensing measurement setup parameters elements.
S504: The DMG SBP responder replies with an SBP response frame (an example of a second message).
If a result of one or more DMG sensing measurement setup response frames complies with a configuration parameter in the DMG SBP initiator, the SBP response frame may carry a status code indicating that an SBP request is accepted, that is, the status code=success. Otherwise, the status code=fail, and this indicates that SBP fails to be established.
S501 to S504 may be referred to as a DMG SBP setup phase and a sensing measurement setup phase.
S505: The sensing responder and the DMG SBP responder perform a sensing measurement.
The sensing measurement includes that one of the sensing responder and the DMG SBP responder sends a sensing PPDU, and the other obtains a sensing measurement result. If the sensing responder obtains the sensing measurement result as a sensing receiver, the sensing responder may send the sensing measurement result to the DMG SBP responder.
S506: After obtaining the sensing measurement result, the SBP responder feeds back the sensing measurement result to the DMG SBP initiator by using a DMG SBP report frame.
S506 is a DMG SBP reporting phase. For a process of S506, refer to the method 300.
After S506, the DMG SBP initiator and the DMG SBP responder may terminate a DMG SBP procedure. For details, refer to the method 400.
S507: The DMG SBP initiator sends a DMG SBP Termination frame to terminate the DMG SBP procedure.
S508: The DMG SBP responder sends the DMG SBP Termination frame to terminate the DMG SBP procedure.
