The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.

1. WLAN perception and participants

WLAN terminals participating in sensing may include a sensing session initiator (Sensing initiator, which may be referred to as the sensing initiator), a sensing session responder (Sensing Responder, which may be referred to as the sensing responder), and a sensing signal transmitter (Sensing transmitter, which may be referred to as the sensing sender) ), sensing signal receiver (Sensing receiver, can be referred to as sensing receiver) and other roles.

For example, referring to Figure 2a, STA1 is a sensing initiator (non-standalone), sensing receiver and sensing processor (Sensing processor); STA2 is a sensing sender. Referring to Fig. 2b, STA1 is a perception initiator (non-independent) and a perception sender; STA2 is a perception receiver and a perception processor. Referring to Fig. 2c, STA1 is a perception initiator (independent) and a perception processor; STA2 is a perception receiver; STA3 is a perception sender. Referring to Fig. 2d, STA1 is a perception initiator (non-independent), a perception receiver and a perception processor; STA2 and STA3 are perception senders. Referring to Fig. 2e, STA1 is a perception initiator (non-independent), a perception sender and a perception processor; STA2 and STA3 are perception receivers. Referring to Fig. 2f, STA1 is a perception initiator (independent), STA2 is a perception receiver and a perception processor, STA3 and STA4 are perception senders. Referring to Fig. 2g, STA1 is a perception initiator (non-independent), a perception sender, a perception receiver and a perception processor. Referring to Fig. 2h, STA1 is a perception initiator (independent), and STA2 is a perception sender, a perception receiver and a perception processor. Referring to Fig. 2i, STA1 is a perception initiator (non-independent), a perception sender, a perception receiver and a perception processor, and STA2 is a perception sender and a perception receiver. Referring to Fig. 2j, STA1 is a perception initiator (independent) and a perception processor, STA2 is a perception sender and a perception receiver, and STA3 is also a perception sender and a perception receiver. In Fig. 2a to Fig. 2j, the solid line arrows represent the illumination signal, the short dotted line arrows represent the sensing measurement, the dotted line arrows represent the sensing result (sensing result), and the long dotted line arrows represent the echo signal ( echo signal). The illumination signal (illumination signal) can also be a sensing measurement signal (sensing measurement), which is attenuated and diffracted by the occlusion of a person, and the signal characteristics change when the sensing receiving device receives it. The illumination signal (illumination signal) is reflected by the person to generate an echo signal (echo signal), and the echo signal is received by the sensing receiving device to perceive the change.

It should be noted that STA only represents the role of STA, and is not used to limit the number of STAs in Figure 2a to Figure 2j and subsequent steps such as sensing sessions and measurements, for example, STAs representing the roles of STA1, STA2, and STA3 for one or more.

2. Overall process of WLAN awareness session

Referring to Figure 3, the WLAN sensing session includes one or more of the following stages: session setup (Session Setup); sensing measurement setting establishment (Measurement Setup); sensing measurement (Measurement); sensing reporting (Reporting); sensing measurement setting end (Measurement Setup) Termination); session end (Session Termination). A WLAN terminal may have one or more roles in a sensing session. For example, the initiator of a sensing session can be only the initiator of a sensing session, or can be a sensing signal sender, a sensing signal receiver, or a sensing signal at the same time. Sender and Receiver of Sensitive Signal.

Session establishment phase: establish a perception session, determine the perception capability and general perception parameters of the device.

Perception measurement setting establishment phase: determine the perception session participants and their roles (including the perception signal sender and the perception signal receiver), decide the operation parameters related to the perception measurement, and optionally exchange the parameters between the terminals.

Perceptual measurement stage: Perceptual measurement is implemented, and the sensory signal sender sends the sensory signal to the sensory signal receiver.

Sensing reporting stage: report measurement results, depending on the application scenario, the receiver of the sensing signal may need to report the measurement results to the initiator of the sensing session.

Perception measurement setting end stage: the terminal ends the corresponding measurement of the measurement setting, and cleans up related resources.

Session end phase: the terminal stops measuring and terminates the sensing session.

3. Negotiation of WLAN sensing measurement setting parameters

When the perception measurement setting is established, the terminals may need to negotiate the perception roles and operation parameters one by one, or the terminals declare their own roles and operation parameters (for example, through beacon frames or other special frames). For example, referring to Figure 4, SENS STA1 may be a Sensing Initiator and Transmitter. SENS STA2 can be Sensing Responder and Receiver. SENS STA3 can be Sensing Responder and Transmitter. Mode 1: Terminal SENS STA1 sends a sensing request (SENS Request) to SENS STA2, and SENS STA2 sends a sensing response (SENS Response). Mode 3: Terminal SENS STA1 sends a sensing request (SENS Request) to SENS STA3, and SENS STA3 sends a sensing response (SENS Response).

4. Measurement settings and measurement examples

The perception session initiator can establish multiple sets of measurement parameters through the Measurement Setup process. A group of measurement parameters can be identified by a measurement setup ID (Measurement Setup ID), and can be applied to multiple measurements (the multiple measurements can be equivalent to a burst group, Burst Group). Each measurement (which can be equivalent to a burst, Burst) can be identified by a measurement instance ID (Measurement Instance ID).

For example, referring to FIG. 5, the association identifier (Association Identifier, AID) of AP=0, the AID of STA1=1, the AID of STA2=2, and the unassociation identifier (Unassociation Identifier, UID) of STA3=3. The AP can establish measurement setups with STA1, STA2, and STA 3 at different time points, and the measurement setup ID (Measurement Setup ID)=1. AP can send perception measurement polling frame, perception announcement frame and perception measurement frame to STA1, STA2, STA 3 at the same time, measurement setting identification=1 and measurement instance identification=1. The AP can simultaneously send the perception measurement polling frame, the perception announcement frame and the perception measurement frame to STA1, STA2, and STA3, and the measurement setting identifier=1 and the measurement instance identifier=2. STA1 may send a perception measurement report frame to the AP, and report the perception measurement result with the measurement setting identifier=1 and the measurement instance identifier=1.

The AP can establish measurement settings with STA2 and STA3 at the same or different time points, and the measurement setting identifier=2. The AP can simultaneously send a perception measurement polling frame, a perception announcement frame and a perception measurement frame to STA1, STA2, and STA 3, with the measurement setting identifier=1 and the measurement instance identifier=3. The AP can send a perception measurement polling frame, a perception announcement frame and a perception measurement frame to STA2 and STA 3 at the same time, with the measurement setting ID=2 and the measurement instance ID=4. STA3 may send a perception measurement report frame to the AP, and report the perception measurement result with the measurement setting identifier=1 and the measurement instance identifier=1. STA2 may send a perception measurement report frame to the AP, and report the perception measurement result with the measurement setting identifier=1 and the measurement instance identifier=1.

5. Measurement process based on trigger frame (Trigger Based, TB)

In some cases, multiple devices participate in perception measurement, and to improve efficiency, a TB measurement process is generally adopted. The process may include polling (Polling), uplink measurement (UL, Uplink, sensing sounding), downlink measurement (DL, Downlink, sensing sounding) and key update (Key update). As shown in Figure 6, STA1 and STA2 are sensing transmitters (Sensing Transmitter), and STA3, STA 4 and STA 5 are sensing receivers (Sensing Receiver).

In the polling (Polling) stage, the AP sends a polling trigger frame to detect whether the participating devices are available. During the uplink measurement (UL sensing sounding) phase, the AP sends trigger frames and NDP frames. In the downlink measurement (DL sensing sounding) AP sends NDPA frames and NDP frames.

Polling should always be here to check the availability of responder STAs before performing the actual sensing measurement.

STA1-4 sends a permission to send frame (Clear To Send-to self, CTS-to-self) to respond to the polling frame, confirming that he can participate in the upcoming perception measurement (Here STA1-4 respond with CTS-to-self to confirm they will participate in upcoming sensing sounding.).

STA 5 did not respond to the CTS-to-self frame, so the AP will not include STA5 in the upcoming sensing measurement (STA5 does not send CTS-to-self back, so AP will not include STA5 in upcoming sensing sounding.) .

Optionally, there is uplink measurement, conditional on at least one sensing transmitters responds in the polling (UL sensing sounding is optionally present, conditioned on at least one sensing transmitters responds in the polling.).

AP sends TF (Trigger Frame, trigger frame) to STA1-2 to request NDP packet transmission for uplink measurement (AP sends a TF to STA1-2 to solicit NDP packet transmission to do UL sensing sounding.).

NDP from STA1-2 can be in UL (Uplink, uplink)-MIMO (Multiple-Input Multiple-Output, multiple input and multiple output)/UL (Uplink, uplink)-OFDMA (Orthogonal Frequency Division Multiple Access, orthogonal frequency division) at the same time Multiple access) to be transmitted (NDP from STA1-2 could be transmitted simultaneously in UL-MIMO/UL-OFDMA).

Optionally, there is a downlink measurement, conditioned on at least one sensing transmitters receiver in the polling (DL sensing sounding is optionally present, conditioned on at least one sensing transmitters receiver in the polling.).

AP sends NDPA+NDP to STA3-4 to perform downlink measurement (AP sends NDPA+NDP to STA3-4 to perform DL sensing sounding).

Key update is optionally present if secure LTF info needs to be updated and communicated to STAs if secure LTF information needs to be updated and communicated to STAs.

The updated information can be carried in an action or management frame (The updated information can be carried in an action or management frame).

6. Reporting process

In perception measurement, the measurement result is explicitly requested by the perception initiating device (such as triggered by a sensory feedback request frame or a sensory report trigger frame in related technology 6) or implicitly requested to report (such as triggered by NDP in related technology 5). The measurement results can be reported immediately (immediate report) or delayed report (delayed report). Delayed reporting is generally explicitly requested by the perception initiating device.

As shown in Figure 7, in the reporting phase, the sensing signal sending device sends a feedback trigger (Trigger) frame after sending the NDP frame, and the sensing signal receiving device is such as receiving device_1 (Receiver_1), receiving device_2 (Receiver_2), receiving device_ After receiving the trigger frame, n (Receiver_n) etc. report the measurement results to the sensing signal sending device, such as measurement feedback_1 (Measurement feedback_1), measurement feedback_2 (Measurement feedback_2), measurement feedback_n (Measurement feedback_n), etc.

Fig. 8 is a schematic flowchart of a communication method 800 according to an embodiment of the present application. The method can optionally be applied to the system shown in Fig. 1, but is not limited thereto. The method includes at least some of the following.

S810. The first device sends first information, where the first information is used to indicate the suspension and/or resumption of the perception measurement setting.

In a possible implementation manner, the first device sends first information to the second device, where the first information is used to instruct the second device to suspend perception measurement setting (which may be referred to as measurement setting or perception setting).

In a possible implementation manner, the first device sends first information to the second device, where the first information is used to instruct the second device to restore the perception measurement setting.

In a possible implementation manner, the first information includes at least one of the following fields:

A field for indicating the first awareness subclass;

a field for indicating a first perception measurement identity;

A field for indicating a list of first perception measurement identifications;

A field to indicate the estimated length of the pause;

Field to indicate the first reason.

In a possible implementation manner, the first perception subclass indicates that the frame carrying the first information is a perception measurement setting pause frame.

Exemplarily, the first device may send a perception measurement setting pause frame carrying the first information to the second device. The perception measurement setting pause frame may also be referred to as a perception measurement setting pause request frame. For example, the frame sent by the first device to the second device may carry a field named Sensing Subtype (Sensing Subtype), and the value of this field indicates the first sensing subtype, which may indicate that the frame is suspended for sensing measurement request frame.

In a possible implementation manner, the first perception measurement identifier includes a perception measurement identifier corresponding to a perception measurement setting that needs to be suspended.

For example, the frame sent by the first device to the second device may carry a field named Measurement Setup ID, and the value of this field indicates the first sensory measurement ID, indicating a sensory measurement setup that needs to be suspended The corresponding perception measurement ID. For example, a perception measurement setting that needs to be suspended includes the parameters used in the measurement (such as the role of the device in the perception, the bandwidth used by the perception, the number of sent airspace flows, the number of received airspace flows, the type of measurement results, etc.), the corresponding perception measurement ID1.

In a possible implementation manner, the first perception measurement identifier list includes multiple perception measurement identifiers corresponding to multiple perception measurement settings that need to be suspended, and different perception measurement identifiers correspond to different perception measurement settings.

For example, the sensory measurement setup pause frame sent by the first device to the second device may carry a field named measurement setup ID (Measurement Setup ID), and the value of this field indicates the list of first sensory measurement IDs, indicating that a pause is required The multiple perceptual measurement identities corresponding to the multiple perceptual measurement settings for . The field for indicating the first perception measurement identity list may include a plurality of fields for indicating the first perception measurement identity. For example, the perception measurement identifier list 1 may include the perception measurement identifier 1, the perception measurement identifier 2, and the perception measurement identifier 3, and different perception measurement identifiers may correspond to different parameters used in the measurement. Perception measurement identification 1 corresponds to a perception measurement setting that needs to be suspended, including parameters used in the measurement (such as the role of the device in perception 1, the bandwidth used for perception 1, the number of sending airspace streams 1, the number of receiving airspace streams 1, and the measurement results type, etc. 1); the perception measurement identification 2 corresponds to a perception measurement setting that needs to be suspended, including the parameters used in the measurement (such as the role of the device in perception 2, the bandwidth used for perception 2, the number of sending airspace streams 2, the receiving airspace flow number 2, type of measurement result 2, etc.); perception measurement identification 3 corresponds to a perception measurement setting that needs to be suspended, including parameters used in the measurement (such as the role of the device in perception 3, the bandwidth used by perception 3, the sending airspace number of streams 3, number of received airspace streams 3, type of measurement result 3, etc.).

In a possible implementation manner, the first reason includes a reason for suspending the perception measurement setting.

In a possible implementation manner, the reason for setting the pause awareness measurement includes at least one of the following:

low self-power;

It has more buffered uplink data to send;

It has more buffered downlink data to send;

It will open point-to-point communication by itself;

Pause indicated by upper layer application.

Exemplarily, the reason for suspending the perception measurement setting is related to the device type and role of the first device. The first device may be an AP or a Non-AP. If the AP is the perception initiating device, the reasons why it requires a pause may be: it has a lot of buffered downlink data to send; the pause indicated by the upper layer application. If the Non-AP is a sensing and responding device, the reasons for its request to suspend may be: its own battery is low; it has more cached uplink data to send; it will start point-to-point communication. If the Non-AP is the perception initiating device, the reasons for its request to suspend may be: its own battery is low; it has more cached uplink data to send; it will start point-to-point communication; the suspension indicated by the upper layer application. If the AP is a sensing and responding device, the reason why it requires a pause may be that it has more buffered downlink data to send.

Different pause reasons can be represented by different values. For example, the field used to indicate the first reason can be realized by reason code (Reason Code). The value of the reason code can indicate the following reasons: 0 means that the self-power is low, and the sensory measurement is suspended in order to save power; 1 means that the self has more cached uplink data to be sent, and the sensory measurement is suspended; 2 means that the self will turn on peer-to-peer Communication (peer-to-peer, P2P), suspend participation in measurement; 3 indicates suspension of upper layer application instruction; 4~255 are reserved. Wherein, the value of this field is only an exemplary introduction, and it can also be set to other values, as long as it is ensured that the value corresponding to each reason code is different from the value of other reason codes.

Exemplarily, the upper layer application may include an application program installed in the first device for implementing certain functions. For example, applications for gesture recognition, face recognition, and other functions.

In a possible implementation, the method further includes:

The first device suspends its own perception measurement setting based on the first reason.

Exemplarily, based on its own device type and role, if the first device determines that there is a reason for suspending the perception measurement setting, it may suspend its own perception measurement setting, and send the first information to the second device to indicate the second The device suspends the same perception measurement setup.

For example, the first device is an AP, and the AP is a sensing initiating device. The first device suspends its own perception measurement setting in at least one of the following situations:

It has a lot of buffered downlink data to be sent, for example, the amount of downlink data buffered by the first device itself that needs to be sent is greater than the downlink data amount threshold;

The suspension indicated by the upper layer application, for example, the station management entity (Station Management Entity, SME) of the first device receives the suspension indication sent by the upper layer application of the first device, and the indication is used to indicate the perception measurement setting that needs to be suspended.

For another example, the first device is an AP, and the AP is a sensing initiating device. The first device suspends its perception measurement setting in the following situation: it has a lot of buffered downlink data to send.

For another example, the first device is a Non-AP, and the Non-AP is a sensing response device. The first device suspends its own perception measurement setting in at least one of the following situations:

The power of the first device is low, for example, the power of the first device is lower than the power threshold;

It has a lot of buffered uplink data to send, for example, the amount of uplink data buffered by the first device itself that needs to be sent is greater than the uplink data amount threshold;

It will start peer-to-peer communication by itself.

The first device is a Non-AP, and the Non-AP is a sensing response device. The first device suspends its own perception measurement setting in at least one of the following situations: its own battery is low; it has more buffered uplink data to send; it will start point-to-point communication; the upper-layer application indicates the suspension.

In a possible implementation manner, the method further includes: when the first device suspends its own perception measurement setting, stopping the timer for detecting expiration.

In a possible implementation manner, the first device is a sensing response device, and the timer is used to detect that the sensing responding device does not receive a sensing measurement instance initiated by the sensing initiating device (second device) after a first length of time elapses, Automatically end the perception measurement settings corresponding to the perception measurement instance. For example, when suspending the measurement setting, the sensing response device stops the timer used to detect expiration, and the timer is used to detect how long the sensing response device itself has not received the sensing initiation (for example, after a first time length, that is, the timing duration of the timer). If the measurement instance initiated by the device (the second device) is detected, the sensing response device automatically ends the measurement setting.

In a possible implementation manner, the first device is a sensing initiating device, and the timer is used to detect that the sensing responding device (second device) does not participate in the sensing measurement instance initiated by the sensing initiating device after a second length of time elapses, Automatically end the perception measurement settings corresponding to the perception measurement instance. For example, when the sensing initiating device suspends the measurement setting, it stops the timer used to detect expiration, and the timer is used to detect how long the sensing responding device (second device) lasts (for example, after a second time length, that is, after the timing of the timer) If the sensing initiating device does not participate in the measurement instance initiated by the sensing initiating device, the sensing initiating device automatically ends the measurement setting.

In a possible implementation manner, the suspension indicated by the upper-layer application is the suspension-aware measurement setting indicated by the upper-layer application of the first device based on a Basic Service Set (Basic Service Set, BSS) load higher than a first set threshold.

For example, the upper layer application may instruct the SME to suspend one or more perception measurement settings based on the BSS load being higher than a first set threshold.

In a possible implementation manner, the BSS load includes at least one of the following:

Channel utilization; available admission time; sensing occupancy; ranging occupancy; sensing and ranging occupancy. For example, the channel utilization is the ratio of the channel busy time to the total estimated time. As another example, the available admission time is the medium access time that can be used for explicit admission control. For another example, the perceived occupancy rate may be the ratio of the perceived occupied time to the total measured time. For another example, the ranging occupancy rate may be a ratio of the time taken for ranging to the total time for measuring and calculating. For another example, the sensing and ranging occupancy rate may be a ratio of the time occupied by sensing and ranging to the total measuring time.

A field for indicating the second awareness subclass;

a field for indicating a second perception measurement identity;

Field to indicate a list of second perception measurement identities.

In a possible implementation manner, the second perception subclass indicates that the frame carrying the first information is a perception measurement setting recovery request frame.

Exemplarily, the first device may send a perception measurement setting recovery request frame carrying the first information to the second device. For example, the frame sent by the first device to the second device may carry a field named Sensing Subtype (Sensing Subtype), and the value of this field indicates the second sensing subtype, which may indicate that the frame is recovery of sensing measurement settings request frame.

In a possible implementation manner, the second perception measurement identifier includes a perception measurement identifier of a perception measurement setting that needs to be restored.

In a possible implementation manner, the second perception measurement identifier list includes a plurality of perception measurement identifiers of the perception measurement settings that need to be restored.

For example, the sensory measurement setup recovery request frame sent by the first device to the second device may carry a field named measurement setup ID (Measurement Setup ID), and the value of this field indicates the second sensory measurement ID list, indicating the need to A plurality of perception measurement identifiers corresponding to the restored plurality of perception measurement settings. The field for indicating the second perception measurement identity list may include a plurality of fields for indicating the second perception measurement identity. For example, the perception measurement identifier list 1 may include perception measurement identifier 1 , perception measurement identifier 2 , and perception measurement identifier 3 . Perception measurement ID 1 corresponds to a perception measurement setting that needs to be restored, including parameters used in the measurement (such as the role of the device in perception 1, the bandwidth used for perception 1, the number of sending airspace streams 1, the number of receiving airspace streams 1, and the measurement results type 1, etc.); perception measurement identification 2 corresponds to a perception measurement setting that needs to be restored, including the parameters used in the measurement (such as the role of the device in perception 2, the bandwidth used for perception 2, the number of sending airspace streams 2, the receiving airspace Flow number 2, measurement result type 2, etc.); a perception measurement setting corresponding to the perception measurement identification 3 that needs to be restored includes parameters used in the measurement (such as the role of the device in the perception 3, the bandwidth used by the perception 3, the sending airspace number of streams 3, number of received airspace streams 3, type of measurement result 3, etc.).

In a possible implementation, the method further includes:

The first device receives second information in response to the first information.

In a possible implementation manner, the first device receives the second information of the second device, and the second information responds to the setting of the pause awareness measurement indicated by the first information.

In a possible implementation manner, the first device sends the first information to the second device, and the second information responds to the recovery awareness measurement setting indicated by the first information.

In a possible implementation manner, the second information includes at least one of the following fields:

A field for indicating a third awareness subclass;

Field to indicate the second reason.

In a possible implementation manner, the third perception subclass indicates that the frame carrying the second information is a perception measurement setting recovery response frame.

Exemplarily, the first device may receive a perception measurement setting recovery response frame carrying the second information from the second device. For example, the frame received by the first device from the second device may carry a field named Sensing Subtype (Sensing Subtype), and the value of this field indicates the third sensing subtype, which may indicate that the frame is recovery of sensing measurement settings response frame.

In a possible implementation manner, the second reason includes a reason for refusing to restore the measurement setting.

In a possible implementation manner, the reason for refusing to restore the measurement setting includes at least one of the following:

The perception measurement settings that need to be restored have been terminated by the perception initiating device and cannot be restored;

Other devices already participate in the perception measurement corresponding to the perception measurement setting instead, and there is no need to restore the perception measurement setting of the first device.

Different reasons for refusal to resume can be represented by different values. For example, the field used to indicate the second reason can be realized by reason code (Reason Code). The value of the reason code can indicate the following reasons for refusal to restore: 0 means that the sensing measurement setting has been terminated by the sensing initiator device and cannot be restored; 1 means that other devices have already participated in the measurement as a substitute, and the device is no longer needed; 2~255 are reserved. Wherein, the value of this field is only an exemplary introduction, and it can also be set to other values, as long as it is ensured that the value corresponding to each reason code is different from the value of other reason codes.

In a possible implementation manner, the second information may further include a field for indicating the fourth perception subclass. The fourth perception subclass may indicate that the frame carrying the second information is a perception measurement setting pause response frame. Perception Measurement Setup Pause frames can be action frames or no-acknowledgement action frames. If the sensory measurement setting pause frame is an action frame, then the sensory measurement setting pause response frame may be an Ack frame; if the sensory measurement setting pause frame is a non-confirmation action frame, then the sensory measurement setting pause response frame may be a single response frame.

In a possible implementation, the field for indicating the first perception subclass, the field for indicating the first perception subclass, the field for indicating the third perception subclass, the field for indicating the fourth perception subclass The fields of can be realized by using different values of the same field. This field adopts different values, and the frames carried respectively are sensory measurement setting pause request frame, sensory measurement setting resume request frame, sensory measurement setting resume response frame, sensory measurement setting pause response frame.

For example, a field named Sensing Subtype may be carried in the frame, and the value of this field may be any value within the range of 0 to 255. An example of the frame type represented by the value of this field is as follows: 0 indicates a proxy request frame (Sensing By Proxy Request frame); 1 indicates a proxy response frame (Sensing By Proxy Response frame); 2 indicates a sensing measurement setup request frame (Sensing Measurement Setup Request frame); 3 means Sensing Measurement Setup Response frame (Sensing Measurement Setup Response frame); 4 means Sensing Measurement Setup Termination frame (Sensing Measurement Setup Termination frame); 5 means Sensing Measurement Setup Termination Request frame (Sensing Measurement Setup Termination Request frame) ; 6 represents the Sensing Measurement Setup Suspend frame (Sensing Measurement Setup Suspend frame); 7 represents the Sensing Measurement Setup Resume Request frame (Sensing Measurement Setup Resume Request frame); 8 represents the Sensing Measurement Setup Resume Response frame (Sensing Measurement Setup Resume Response frame); 9 to 15 reserved. The meaning represented by the value of this field is only an example, not a limitation, and can be flexibly set according to actual application requirements.

In a possible implementation manner, the method further includes: the first device resumes its suspended perception measurement setting based on the resume indicated by the upper layer application. For example, the SME of the first device receives a recovery indication sent by an upper-layer application of the first device, and the indication is used to indicate the perception measurement settings that need to be recovered. The first device may restore its own suspended perception measurement settings based on the restoration indicated by the upper layer application. For example, if the resumption indicated by the upper layer application includes perception measurement setting 1 and perception measurement setting 2 that need to be resumed, the first device resumes the suspended perception measurement setting 1 and perception measurement setting 2 . The upper-layer application of the first device can invoke the software interface provided by the SME to restore the suspended sensory measurement setting 1 and sensory measurement setting 2 .

In a possible implementation manner, the restoration indicated by the upper-layer application is the restoration-aware measurement setting indicated by the upper-layer application of the first device based on the BSS load being lower than the second set threshold.

For example, the upper layer application may instruct the SME to resume one or more suspended perception measurement settings if the load based on the BSS is below a second set threshold. For a specific example of the BSS load, refer to the relevant description above. The second set threshold in this example may be the same as or different from the above-mentioned first set threshold for determining whether to suspend the perception measurement setting.

In a possible implementation manner, the method further includes: when the first device restores its own suspended perception measurement setting, restarting the timer for detecting expiration.

For example, the first device is a sensory response device. After restarting the timer for detecting expiration, the timer re-detects how long the sensory response device itself has not received (for example, after a first time period, that is, the timer's timing period). Upon reaching the measurement instance initiated by the sensing initiating device (the second device), the sensing responding device automatically ends the measurement setting.

For another example, the first device is the sensing initiating device. After restarting the timer for detecting expiration, how long the timer will continue to detect the sensing responding device (the second device) (for example, after a second length of time, that is, the timer's After a predetermined period of time) does not participate in the measurement instance initiated by the sensing initiating device, the sensing initiating device will automatically end the measurement setting.

In a possible implementation manner, the SME of the first device provides at least one of the following interfaces for the upper layer application of the first device:

Interfaces for establishing and/or ending perception measurement setups;

Interface for pausing and/or resuming perception measurement setup;

An interface for reporting perception measurement results;

An interface for reporting execution status.

For example, the first device includes an upper-layer application, an SME, and a media access control (Medium Access Control, MAC) sub-layer management entity. The above-mentioned one or more interfaces provided by the SME of the first device for its own upper-layer applications may be used to manage the WLAN awareness process. The upper-layer application calls the interface to perform corresponding actions. For example, the upper layer application invokes an interface for suspending the perception measurement setting, and the first device may send a perception measurement setting pause frame for instructing to suspend the perception measurement setting to the second device. For another example, the upper layer application invokes the interface for restoring the perception measurement setting, and the first device may send a perception measurement setting restoration request frame to the second device for instructing to restore the perception measurement setting.

In a possible implementation, the interface for reporting the execution state is used to report at least one of the following to the upper layer application: operation type; operation status code; measurement setting identification; measurement identification list identification; failure reason code; exception related information.

In a possible implementation manner, the operation type includes at least one of the following: establishing measurement setting; ending measurement setting; suspending measurement setting; resuming measurement setting;

In a possible implementation manner, the status code of the operation may include a code indicating that the operation is successful and/or a code indicating that the operation has failed. For example, 1 for success and 0 for failure.

In a possible implementation manner, the SME reports the measurement setting identifier and/or the measurement identifier list identifier to the upper-layer application through the interface for reporting the execution state, and can inform the upper-layer application which measurement settings have been specifically operated.

In a possible implementation manner, the failure reason code may indicate a reason for failure to execute a certain operation. For example, the first device sends a sensory measurement setting recovery request frame for instructing recovery of sensory measurement settings to the second device, but since the sensory measurement settings that need to be recovered have been completed by the second device, such as the sensory initiating device, the second device refuses to restore The perception measurement is set. At this time, the second device may return a reason code 0 to the first device through the perception measurement setting restoration response frame, indicating the reason why the second device refuses to restore the perception measurement setting.

In a possible implementation manner, the relevant information about the abnormality is used to indicate at least one of the following: BSS overload; information about BSS load.

For example, the relevant information of the exception may include the error code of the exception and specific additional information. Unusual error codes can indicate that the BSS is overloaded. The specific additional information may represent the information of the BSS load.

In a possible implementation manner, the method further includes: the interface for suspending and/or resuming sensing measurement settings of the SME is called by the upper layer application of the first device, and sends the first information to the second device to indicate that the first device The second device suspends and/or resumes the sensing measurement setting; after the second device suspends and/or resumes the sensing measurement setting, the SME returns the information of suspending and/or resuming the sensing measurement setting to the upper layer application.

In this manner, the SME of the first device may report the information of suspending and/or resuming the perception measurement setting to the upper layer application of the first device after the execution of the second device is finished. For example, the upper layer application of the first device calls the interface of suspending the sensing measurement setting of the SME, and the SME sends the first information to the second device to instruct the second device to suspend the sensing measurement setting; the SME suspends the sensing measurement setting on the second device After that, return the information of suspend-aware measurement setting to the upper-layer application. For another example, the upper layer application of the first device invokes the interface of the SME for restoring the sensing measurement setting, and the SME sends the first information to the second device to instruct the second device to restore the sensing measurement setting; the SME restores the sensing measurement setting on the second device. After setting, return the information to restore the perception measurement setting to the upper application.

In a possible implementation, the method further includes: the interface of suspending and/or resuming the sensing measurement setting of the SME is invoked by an upper-layer application of the first device, and returning the suspending and/or resuming sensing measurement setting to the upper-layer application information; the SME sends the first information to the second device to instruct the second device to suspend and/or resume the sensing measurement setting; after the second device suspends and/or resumes the sensing measurement setting, the SME applies to the upper layer Returns information about the success or failure of the execution.

In this way, the SME of the first device can report the information of suspending and/or resuming the perception measurement setting to the upper layer application of the first device after the interface is called; The application reports execution success or failure information. For example, the upper layer application of the first device calls the interface of the SME to suspend the sensing measurement setting, and the SME returns the information of suspending the sensing measurement setting to the upper layer application; the SME sends the first information to the second device to instruct the second device to suspend the sensing measurement Setting; after the second device suspends the perception measurement setting, the SME returns information about execution success or failure to the upper layer application. For another example, the upper-layer application of the first device invokes the interface of the SME to restore the sensing measurement setting, and the SME returns the information of restoring the sensing measurement setting to the upper-layer application; the SME sends the first information to the second device to instruct the second device to suspend And/or restore the perception measurement setting; after the second device restores the perception measurement setting, the SME returns the execution success or failure information to the upper application.

In a possible implementation manner, the method further includes: the interface for suspending and/or resuming sensing measurement settings of the SME is called by the upper layer application of the first device, and sends the first information to the second device to indicate that the first device The second device suspends and/or resumes the sensing measurement setting; after the second device suspends and/or resumes the sensing measurement setting, the SME returns the information of suspending and/or resuming the sensing measurement setting to the upper layer application, and the execution success or failure information.

In this way, the SME of the first device can report the information of suspending and/or resuming the perception measurement setting, and the information of execution success or failure to the upper layer application of the first device after the execution of the second device is completed. For example, the upper layer application of the first device calls the interface of suspending the sensing measurement setting of the SME, and the SME sends the first information to the second device to instruct the second device to suspend the sensing measurement setting; the SME suspends the sensing measurement setting on the second device After that, return the information of suspending awareness measurement setting and the information of execution success or failure to the upper layer application. For another example, the upper layer application of the first device invokes the interface of the SME for restoring the sensing measurement setting, and the SME sends the first information to the second device to instruct the second device to restore the sensing measurement setting; the SME restores the sensing measurement setting on the second device. After setting, return the information of restoring the perception measurement setting to the upper layer application, and the information of execution success or failure.

The method for managing measurement settings in this embodiment of the present application may include suspending and/or resuming measurement settings, which may specifically include the following:

1. Management of perception process

The Site Management Entity (SME) in the site provides the following interfaces for its own upper-layer applications to manage the WLAN awareness process:

At least one of an interface for establishing and ending a perception measurement setup, an interface for suspending and resuming a measurement setup, an interface for reporting measurement results, and an interface for reporting execution status.

As shown in Fig. 10a and Fig. 10b, the upper layer application of the perception initiating device (for example, the gesture recognition application program) suspends the perception measurement because the upper layer application is switched to the background, for example, calls its internal SME pause measurement setting implemented by the driver program Interface that instructs one or more sensory-responsive devices to suspend measurement setup for gesture recognition.

It specifically includes: SME instructs MLME to generate a measurement setting pause request frame by invoking the measurement setting pause request primitive provided by the MAC sublayer management entity (MAC sublayer management entity, MLME), and sends the request to one or more Sense Response Devices. After receiving the measurement setting pause request frame, the sensing response device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing response device reports the measurement setting suspension information to its SME through the measurement setting suspension notification primitive. The SME of the Sense Response Device processes this information and instructs the MLME to generate a Measurement Setup Suspend Response frame and send this response over the physical layer interface by invoking the Measurement Setup Suspend Response primitive provided by the MLME. After receiving the measurement setting pause response frame, the sensing initiating device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing initiating device reports the measurement setting suspension response information to its SME through the measurement setting suspension confirmation primitive. After the execution is completed, the SME that perceives the initiating device returns execution success or failure to the upper layer application (option 1). Alternatively, after the upper-layer application of the sensing initiating device invokes the SME interface, its SME immediately returns execution success or failure, and reports execution success or failure to the upper-layer application after the SME is executed (option 2). Or, after the SME of the sensing initiating device completes the execution, it returns execution success or failure to the upper-layer application, and reports the execution success or failure to the upper-layer application (option 3).

For option 1, the "pause measurement setting return" in Fig. 10a may contain at least one of the actual operation execution success or failure, failure reason code and more specific reason information. In the case of success, generally only an indication of success is required. For option 2, the "pause measurement setting return" in Figure 10a can include the success or failure of the interface call; the "report execution status" can include at least one of the success or failure of the actual operation execution, the reason code of the failure, and more specific reason information . For option 3, "pause measurement setup return" in Fig. 10b may contain actual operation execution success or failure. The "report execution status" may include at least one of the actual operation execution success or failure, failure reason code and more specific reason information.

The upper-layer application may indicate through the interface for suspending the measurement setting: at least one of a measurement setting identifier (or called a perception measurement setting identifier), a list of measurement setting identifiers, and an expected pause duration.

The SME can indicate at least one of the following to the upper layer application through the interface for reporting the execution status: operation type, operation status code, measurement setup ID, failure reason code, exception error code and exception related information. For example, the operation type may include at least one of the following: establish measurement settings, end measurement settings, suspend measurement settings, resume measurement settings, and report abnormalities. As another example, an operation's status code can indicate success or failure.

As shown in Figure 11, the sensing response device can also request to suspend the measurement setting, and the SME of the sensing initiating device reports the execution status to the upper layer application (the opposite end requests to suspend the measurement setting). Specifically, the SME of the sensing response device instructs the MLME to generate a measurement setting pause request frame by invoking the measurement setting pause request primitive provided by the MLME, and sends the request to the sensing initiating device through a physical layer interface. After receiving the measurement setting pause request frame, the sensing initiating device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing initiating device reports the measurement setting suspension request information to its SME through the measurement setting suspension request notification primitive. The SME of the sensing initiating device processes the information and reports to the upper layer application that the one or more measurement settings of the sensing responding device have been suspended. At the same time, the SME of the sensing initiating device also instructs the MLME to generate a measurement setting pause response frame and send the frame through the physical layer interface by invoking the measurement setting pause response primitive provided by the MLME. After receiving the measurement setting pause response frame, the sensing response device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing response device reports the measurement setting suspension response information to its SME through the measurement setting suspension confirmation primitive.

As shown in Fig. 12a and Fig. 12b, the upper-layer application (such as a gesture recognition application) of the sensing initiating device restores the sensing measurement because the upper-layer application switches back to the foreground from the background, for example, calls its internal SME recovery measurement implemented by the driver An interface for settings that instructs one or more sensory-responsive devices to restore measurement settings for gesture recognition.

Specifically, the SME instructs the MLME to generate a measurement setting recovery request frame by invoking the measurement setting recovery request primitive provided by the MLME, and sends the request to one or more sensing response devices through a physical layer interface. After receiving the measurement setting recovery request frame, the sensing response device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing response device reports the measurement setting recovery information to its SME through the measurement setting recovery notification primitive. The SME of the Sense Response Device processes this information and instructs the MLME to generate a Measurement Setup Resume Response frame and send it over the physical layer interface by invoking the Measurement Setup Resume Response primitive provided by the MLME. After receiving the measurement setting recovery response frame, the sensing initiating device reports the frame to its own MLME through the physical layer interface. The MLME of the perception initiating device reports the measurement setting recovery response information to its SME through the measurement setting recovery confirmation primitive. After the execution is completed, the SME that perceives the initiating device returns execution success or failure to the upper layer application (option 1). Alternatively, the SME returns immediately after the upper-layer application of the sensing initiating device invokes the SME interface, and reports execution success or failure to the upper-layer application after the SME is executed (option 2). Or, after the SME of the sensing initiating device completes the execution, it returns execution success or failure to the upper-layer application, and reports the execution success or failure to the upper-layer application (option 3).

For option 1, "resume measurement setting return" in Fig. 12a may contain at least one of actual operation execution success or failure, failure reason code and more specific reason information. In the case of success, generally only an indication of success is required. For option 2, the "Resume Measurement Setting Return" in Figure 12a can include the success or failure of the interface call; the "Report Execution Status" can include at least one of the success or failure of the actual operation execution, the reason code of the failure, and more specific reason information . For option 3, the "Resume Measurement Setting Return" in Figure 12b may include the success or failure of the actual operation execution; one.

Through the interface for restoring measurement settings, the upper layer application may indicate: a measurement setting identifier (or called a perception measurement setting identifier) and/or a list of measurement setting identifiers.

As shown in Figure 13, the sensing response device can also request to restore the measurement settings, and the SME of the sensing initiating device reports the execution status to the upper layer application (the peer end requests to restore the measurement settings). Specifically, the SME of the sensing response device instructs the MLME to generate a measurement setting restoration request frame by invoking the measurement setting restoration request primitive provided by the MLME and sends the request to the sensing initiation device through a physical layer interface. After receiving the measurement setting recovery request frame, the sensing initiating device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing initiating device reports the measurement setting recovery request information to its SME through the measurement setting recovery request notification primitive. The SME of the sensing initiating device processes the information and reports to the upper layer application that the one or more measurement settings of the sensing responding device have been restored. At the same time, the SME of the sensing initiating device also instructs the MLME to generate a measurement setting recovery response frame and send the frame through the physical layer interface by invoking the measurement setting recovery response primitive provided by the MLME. After receiving the measurement setting recovery response frame, the sensing response device reports the frame to its own MLME through the physical layer interface. The MLME of the sensing response device reports the measurement setting recovery response information to its SME through the measurement setting recovery confirmation primitive.

In one embodiment, the AP can judge the BSS load situation by measuring indicators such as channel utilization rate and available access time. In areas such as office buildings, shopping malls, stadiums, and exhibition halls, the BSS load may be relatively high. For example, channel utilization may include the ratio of channel busy time to total estimated time. The ratio of 0-100% can be expressed linearly by using 0-M to express the busyness of the medium perceived by the AP, and M can be 2 ⁿ , where n=2, 3, 4, 5, 6, 7, 8, 9, 10. In one embodiment, a value from 0-255 is used to linearly represent a ratio from 0-100% (the percentage of time, linearly scaled with 255 representing 100%, that the AP sensed the medium was busy). As another example, the available admission time may include the remaining amount of medium time available via explicit admission control.

In order to give priority to ensuring the user experience of communication, when the load of the BSS is relatively high, it is necessary to make corresponding adjustments to the perception measurement, for example, to suspend the perception measurement setting. The AP can also calculate perception occupancy rate (using 0-M linear representation 0-100%), ranging occupancy rate, perception and ranging occupancy rate, etc. to assist in decision-making and processing of perception when the processing load is high. . For example, the perceived occupancy rate may include the ratio of the time perceived to be occupied to the total time measured. For another example, the ranging occupancy rate may include a ratio of the time occupied by the ranging to the total time for measuring. For another example, the sensing and ranging occupancy rate may include a ratio of time occupied by sensing and ranging to the total measuring time.

When the perception initiating device (such as AP STA) judges that the BSS load is high, it indicates at least one of the following to the upper layer application through the interface for reporting the execution status: measurement setting identification, error code (specifically BSS overload), BSS load information (such as channel utilization, available admission time, perceived occupancy, ranging occupancy, and perceived and ranging occupancy).

When the load is higher than the first preset threshold, the upper-layer application can automatically confirm the suspension measurement setting, for example, the upper-layer application instructs the sensing initiation device and all sensing response devices involved in the sensing setting to suspend the sensing setting through the interface of suspending the measurement setting. When the load is higher than the first preset threshold, the upper layer application may also prompt the user to confirm whether to suspend the measurement setting, such as suspending the aforementioned perception setting.

If the BSS load decreases after a period of time, that is, when the load is lower than the second preset threshold, the upper-layer application can automatically confirm the recovery of the measurement settings. For example, through the interface of restoring the measurement settings, indicate the sensing initiation device and all sensing devices involved in the sensing settings. The responding device restores the awareness setting. When the load is lower than the second preset threshold, the upper-layer application may also prompt the user to confirm whether to restore the measurement setting, for example, restore the aforementioned perception setting.

2. Pause measurement setting

A sensing initiating device and/or a sensing responding device may suspend and resume one or more measurement settings. Possible application scenarios for suspending and resuming measurement settings, for example, when the upper-layer application switches to the background, it instructs to suspend the corresponding measurement settings, and when the upper-layer application switches back to the foreground, it instructs to resume the corresponding measurement settings.

When the perception initiating device suspends the measurement setting, it can optionally indicate the expected duration of the suspension, and optionally, it can also indicate the reason for suspending the measurement setting (for example, it is represented by a reason code, and the frame format is shown in Figure 14 and Figure 15 ), including but not limited to: the suspension indicated by the upper layer application; there are more buffered downlink data to be sent, and the perception measurement is suspended.

When the sensory response device suspends the measurement setting, it can optionally indicate the expected duration of the suspension, and optionally, it can also indicate the reason for suspending the measurement setting (for example, it is represented by a reason code, and the frame format is shown in Figure 14 and Figure 15 ), including but not limited to: its own power is low, and it suspends participation in sensing measurement in order to save power; it has more buffered uplink data to send, and suspends participation in sensing measurement; it will turn on point-to-point communication (P2P), and suspend participation in measurement.

When suspending the measurement setting, the sensing response device should also stop the timer for detecting expiration. The timer is used to detect how long the sensing responding device has not received the measurement instance initiated by the sensing initiating device. The sensing responding device will automatically end the measurement setting.

Alternatively, the sensing initiating device should also stop the timer used to detect expiration when suspending the measurement setting. The timer is used to detect how long the sensing responding device does not participate in the measurement instance initiated by the sensing initiating device. The sensing initiating device will automatically end the measurement. set up.

As shown in Figure 14, the Sensing Measurement Setup Suspend frame (Sensing Measurement Setup Suspend frame) is used to suspend a certain measurement setup. As shown in Figure 15, the Sensing Measurement Setup Suspend frame (Sensing Measurement Setup Suspend frame) is used to indicate the suspension of one or more measurement setups.

An embodiment such as Fig. 14 or Fig. 15 provides a sensing action frame (Sensing Action frame): a new action frame (Action frame) or no confirmation action frame (Action No Ack), and the action category (Category) is 4 representations This frame is a public action frame (Public Action frame), and the value of the public action subclass (Public Acton Field) is 51, indicating that the frame is a perception action frame (you can use any value within the range of 46 to 255 to indicate that the frame is a perception action frame) , the Sensing Subtype value is 6 (any value within the range of 0 to 255 can be used) to indicate the Sensing Measurement Setup Suspend frame (Sensing Measurement Setup Suspend frame). If the perception measurement setting pause frame is an action frame, the peer end returns an Ack frame to indicate confirmation; the perception measurement setting pause frame is a non-confirmation action frame, and the peer end needs to return a separate response frame.

Sensing subtype (SENS Subtype) field: 0 means proxy request frame (Sensing By Proxy Request frame); 1 means proxy response frame (Sensing By Proxy Response frame); 2 means sensing measurement setup request frame (Sensing Measurement Setup Request frame); 3 means Sensing Measurement Setup Response frame; 4 means Sensing Measurement Setup Termination frame; 5 means Sensing Measurement Setup Termination Request frame; 6 means sensing Sensing Measurement Setup Suspend frame; 7 means Sensing Measurement Setup Resume Request frame; 8 means Sensing Measurement Setup Resume Response frame; 9~15 reserved .
