In daily life, signals emitted by Wi-Fi devices are usually received after being reflected, diffracted and scattered by various obstacles. This phenomenon makes the actual received signal often the superposition of multiple signals, that is, the channel The environment may become complex, but from another perspective, this also brings convenience to the perception of the physical environment it passes through through wireless signals. By analyzing wireless signals affected by various obstacles, such as channel state information (CSI), etc., the surrounding environment can be inferred and perceived, and WLAN sensing technology is derived from this. Due to the broadcast deployment of Wi-Fi devices and the increase in sensing requirements, sensing using commonly available Wi-Fi devices is a current research hotspot.

Currently, there are mainly the following roles in WLAN sensing technology:

(1) Sensing initiator: the site that initiates a sensing process.

sensing initiator:a STA that initiates a WLAN sensing procedure.

(2) Sensing responder: a station that participates in a sensing process initiated by the sensing initiator.

sensing responder:a STA that participates in a WLAN sensing procedure initiated by a sensing initiator.

(3) Sensing sending end: The station that sends the physical layer protocol data unit (PPDU) used for sensing measurement during the sensing process.

sensing transmitter:a STA that transmits PPDUs used for sensing measurements in a sensing procedure.

(4) Sensing receiver: A station that receives the PPDU sent by the sensing sender and performs sensing measurements during the sensing process.

sensing receiver:a STA that receives PPDUs sent by a sensing transmitter and performs sensing measurements in a sensing procedure.

The perception process can be used to describe how to perform perception. The perception process can include the following five steps:

1) Sensing session setup: Indicates the establishment of a sensing session between sites. Some parameters related to perception can be interacted here (specifics to be determined). Note: The sensing period is an agreement between two sites reached by a sensing initiator and a sensing responder. A sensing initiator can maintain sensing periods with multiple sensing responders, but they still need to be established one by one, for example, through orthogonal frequency division multiple access (OFDMA) mode, multi-user-multiple input multiple access Output (multi-user multiple-input multiple-output, MU-MIMO) mode, etc.

2) Sensing measurement setup: Used for the sensing initiator and the responder to exchange and unify certain parameters, attributes, etc. that need to be used in the sensing process, such as the roles of the sensing initiator and the responder, measurement feedback types, etc. Parameters, for example, the role of the responder can include sensing sender and sensing receiver. Perceptual measurement setup may be simply referred to as measurement setup. The establishment of perception measurement can be identified by <identification of the perception initiator, identification of perception measurement establishment>.

3) Sensing measurement entity (sensing measurement instance): Sensing measurement occurs in the sensing measurement entity. Multiple sensing responders are allowed to join a sensing measurement entity. The establishment of a perceptual measurement entity can also be called a perceptual measurement instance, and the perceptual measurement entity can be referred to as a measurement entity or entity for short. Perceptual measurement entities identified by the same perceptual measurement establishment can be identified by the perceptual measurement entity identifier.

4) Sensing measurement setup termination: Sensing measurement setup termination The process used to terminate the measurement setup corresponding to a certain sensing responder. After termination, the sensing responder is no longer bound to the corresponding measurement setup, but can still be in the sensing period. Sensing measurement establishment termination may be simply referred to as measurement establishment termination.

5) Sensing session termination: Indicates the termination of the sensing period, and the station will no longer participate in sensing measurement and other processes.

Figure 2 gives a schematic diagram of a sensing process to illustrate how the above sensing process is performed. Specifically, Figure 2 shows 16 links in the sensing process. These 16 links can indicate the specific flow of the sensing process. In Figure 2, the abscissa is time T.

Step 1 means adding the site (recorded as site #1) with the medium access control (MAC) address A and the association identifier (AID) 1 to the sensing period, which is the process of establishing the sensing period.

Step 2 is to configure relevant parameters for site #1, that is, the perception measurement is established. In order to clearly identify it, the method of establishing a label for the perception measurement is adopted. In step 2, the measurement establishment identifier (identifier, ID) is 1, that is, the measurement is established. 1.

Link 3 is a measurement entity. A measurement entity establishes an identity binding with a perception measurement. Therefore, the measurement entity can measure site #1 with AID=1. Each measurement entity also has a corresponding label. The ID of the measurement entity in link 3 is 1, that is, measurement entity 1, and measurement entity 1 is bound to measurement establishment 1.

In summary, the role of links 1, 2, and 3 is to add site #1 to the sensing period and start measurement and feedback.

Link 4 identifies that another measurement entity has occurred. To distinguish it from the previous measurement entity, the identification of the measurement entity here is +1, which becomes measurement entity 2 under measurement establishment 1.

Links 5 and 6 are similar to links 2 and 3. Their function is to configure measurement establishment 2 for site #1, and perform measurement and feedback through measurement entity 1 under measurement establishment 2.

Links 7, 8, and 9 are similar to links 1, 2, and 3. Their function is to add the site with an Unassociated Identifier (UID) of 2 (recorded as site #2) to the sensing period, and assign the measurement establishment ID = 2. , and measurement entity 2 occurs thereafter. Therefore, in step 9, sites with AID=1 and UID=2 will be measured in measurement entity 2 under measurement setup 2. That is, sites with AID=1 and UID=2 can participate in sensing measurement and feedback at the same time.

Link 10 is the termination of measurement establishment, which means unbinding the site of AID 1 from measurement establishment 2.

Links 11 and 12 indicate that the site configuration measurement establishment 1 with UID=2 is followed by measurement entity 3. Therefore, in step 12, the sites with AID=1 and UID=2 will be measured in measurement entity 3 under measurement establishment 1.

It should be understood that although the site of AID 1 is unbound from measurement establishment 2 in link 10, the site of AID 1 is still in the sensing period. Therefore, the site of AID 1 can still be measured in measurement entity 3 under measurement establishment 1. .

Link 13 is the end of the sensing period, which means that the site with AID=1 exits the sensing period.

Links 14, 15, and 16 are similar to links 1, 2, and 3, indicating that the site with AID=3 will be added to the sensing period and the binding measurement establishment ID=2. Therefore, in link 16, the sites with AID=3 and UID=2 will Measurement is performed in measurement entity 3 under measurement setup 2, that is, the corresponding stations with AID=3 and UID=2 can participate in sensing measurement and feedback at the same time.

It should be understood that the sensing initiators in the 16 links shown in Figure 2 are the same device.

The perception measurement entity link in Figure 2 can be regarded as a one-to-many establishment link, that is, in a perception measurement entity, a perception initiator can enable multiple perception responders to participate in perception measurement and feedback at the same time, while the other links are all one Establish a link one to one.

Figure 3 is a one-to-one establishment process, in which the sensing entity establishment, sensing measurement establishment, and measurement establishment in Figure 3 Termination and sensing period termination are both accomplished through one-to-one establishment. Taking the sensing period establishment process as an example, the establishment of a sensing period corresponds to a sensing initiator and a sensing responder. Of course, the sensing initiator can also establish this process with multiple stations at the same time, such as using OFDMA or MU-MIMO, but this is the establishment of multiple sensing periods at the same time and cannot be counted as one.

For the measurement entity link, it is different from the four links shown in Figure 3. One-to-many situations can occur in a measurement entity, such as one-to-many declaration and triggering.

Currently, the sensing process supports trigger-based (TB) sensing process and non-trigger-based sensing process. In the trigger-based sensing process, trigger frames can be used to trigger feedback from the peer device. In the trigger-based sensing process, after the sensing period is established and the measurement is established, sensing devices can perform a process of sending and receiving sensing measurement entities based on trigger frames.

Figure 4 gives several examples of perceptual measurement entities. As shown in Figure 4 (a) and Figure 4 (b), the sensing measurement entity includes the polling phase (polling phase), null data PPDU announcement (null data PPDU announcement, NDPA) detection phase (NDPA sounding phase), and reporting reporting phase. As shown in Figure 4 (c), Figure 4 (d), and Figure 4 (e), the perception measurement entity includes the polling phase (polling phase) and the null data PPDU announcement (null data PPDU announcement, NDPA) detection phase (NDPA sounding phase), trigger frame (trigger frame, TF) detection phase (TF sounding phase), reporting phase (reporting phase).

It should be understood that the five perception measurement entities shown in Figure 4 are all trigger-based (TB) perception measurement entities.

Generally speaking, the perception initiator can interact with the perception responder in the perception measurement entity shown in Figure 4. Specifically, the stages included in the perception measurement entity shown in Figure 4 are introduced as follows.

The sensing initiator consults users interested in participating in the measurement entity during the polling phase.

The sensing initiator sends NDPA and null data PPDU (null data PPDU, NDP) to the sensing responder in the NDPA sounding phase. Among them, NDPA and NDP are PPDU used for perception measurement. It should be understood that in this stage, the sensing initiating end is the sensing sending end, and the sensing responding end is the sensing receiving end.

The sensing initiator sends a trigger frame to the sensing responder in the TF sounding phase, and the sensing responder sends NDP under the trigger of the trigger frame, where NDP is the PPDU used for sensing measurement. It should be understood that in this stage, the sensing responder is the sensing sender, and the sensing initiator is the sensing receiver.

The sensing initiator sends a trigger frame to the sensing responder in the reporting phase, triggering the sensing responder to feedback sensing content, which includes sensing measurement results.

In the above reporting stage, there are two modes of feedback: immediate feedback and delayed feedback. When the negotiation between two devices is immediate feedback, the reporting stage in the perception measurement entity will feed back the perception measurement results in the same perception measurement entity. When the negotiation between two devices is delayed feedback, the reporting phase in the perception measurement entity will feed back the perception measurement results in a previous perception measurement entity.

Figure 5 shows a schematic diagram of immediate feedback and delayed feedback. Among them, Figure 5 (a) is a schematic diagram of immediate feedback. As shown in Figure 5 (a), measurement entities 1, 2, 3, and 4 in measurement setup 1 respectively feed back their own perception measurement results. Figure 5 (b) is a schematic diagram of delayed feedback. As shown in Figure 5 (b), the reporting stage in the latter measurement entity will report the measurement results obtained based on the measurement entity corresponding to the previous identical measurement establishment identifier. Specifically, measurement entity 2 in measurement setup 1 feeds back the perception measurement results of measurement entity 1, measurement entity 3 feeds back the perception measurement results of measurement entity 2, and measurement entity 4 feeds back the perception measurement results of measurement entity 3. Understandably, the measurement entity 2 occurs after measurement entity 1, measurement entity 3 occurs after measurement entity 2, and measurement entity 4 occurs after measurement entity 3.

It should be understood that for delayed feedback, there is no limit to how long ago the feedback results are. Figure 5(b) is an example of delaying feedback from a measurement entity. For example, in (b) of Figure 5, the measurement entity of the measurement is the same as the sensing measurement setup ID (measurement setup ID) of the corresponding feedback measurement entity.

In order to further improve feedback efficiency, it is currently proposed to support the following methods: for delayed feedback, the perception measurement report frame of a perception responder can carry measurement reports measured by multiple measurement entities corresponding to the perception measurement establishment identification. In other words, the perceptual measurement entity identified as x in the perceptual measurement establishment can report the results measured by the perceptual measurement entity identified as y in the perceptual measurement establishment, where x and y are positive integers, x and y can be the same, or different.

However, this method only allows the perceptual measurement entity identified as x to be established to feedback the measurement results obtained by the perceptual measurement entity identified as y based on the perceptual measurement establishment. For specific implementation methods, for example, when to perform feedback and how to perform it. Feedback and other designs are not clearly stated.

In view of this, this application provides a method for sensing, and provides an implementation method of delayed feedback, so that the responding device can report sensing measurement results based on the delayed feedback mode.

Figure 6 is a schematic flowchart of a sensing method 200 provided by an embodiment of the present application. For Figure 6, reference may be made to the description of Figures 1 to 5 above.

S210: The second device sends the first information to the first device in the first perception measurement entity, and accordingly, the first device receives the first information.

Optionally, method 200 also includes: the second device generates the first information.

The first information is used to instruct the first device to feed back the perception content of the second perception measurement entity.

In other words, through the first information, the receiving end can learn which one or which second perception measurement entity refers to. The first information can also be understood as instructing the first device to perform delayed feedback and instructing the second perception measurement entity.

It should be understood that the second perception measurement entity may be one perception measurement entity or multiple perception measurement entities, which is not limited by this application.

As an example, the feedback content of the second perception measurement entity has not been fed back by any perception measurement entity. In other words, the second perception measurement entity in this application may be a perception measurement entity whose perception content is not fed back.

The perceptual content of the second perceptual measurement entity refers to the content obtained during the occurrence of the second perceptual measurement entity, which includes the perceptual measurement result of the second perceptual measurement entity.

Wherein, the second perception measurement entity and the first perception measurement entity are different perception measurement entities. It may also be that the second perception measurement entity is different from the first perception measurement entity, or the second perception measurement entity and the first perception measurement entity are not the same perception measurement entity.

Optionally, in an implementation manner, the first perception measurement entity identifier is used to identify the first perception measurement entity, the second perception measurement entity identifier is used to identify the second perception measurement entity, and the first perception measurement entity identifier corresponds to the first perception measurement entity. The perception measurement establishment identification, the second perception measurement entity identification corresponds to the second perception measurement establishment identification. At this time, the first perception measurement entity and the second perception measurement entity are different perception measurement entities, including the following two situations:

Case 1: The first perception measurement establishment identification and the second perception measurement establishment identification are the same, and the first perception measurement entity identification and the second perception measurement entity identification are different.

Case 2: The first perception measurement establishment identification and the second perception measurement establishment identification are different, and the first perception measurement entity identification and the second perception measurement entity identification are the same or different.

Among them, if it is case 1, method 200 can be understood as delayed feedback of non-cross identifier. If it is case 2, method 200 can be understood as delayed feedback across identifiers. Among them, the identification here refers to the identification established by perceptual measurement.

In addition, case 1 and case 2 can exist independently, or case 1 and case 2 can exist simultaneously. For example, when there are multiple second perception measurement entities, the feedback of the perception content of part of the second perception measurement entities belongs to case 1, and the feedback of the perception content of another part of the second perception measurement entity belongs to case 2. At this time, the cross-identification The delayed feedback of and non-cross-identified delayed feedback are sent at the same time.

It should be understood that the first perception measurement entity corresponds to the first perception measurement establishment, and the first perception measurement establishment identifier is used to identify the first perception measurement establishment. Similarly, the second perception measurement entity corresponds to the second perception measurement establishment, and the second perception measurement establishment identifier is used to identify the second perception measurement establishment. Among them, "the first perception measurement establishment identifier and the second perception measurement establishment identification are the same" can be understood as the first perception measurement establishment and the second perception measurement establishment are the same, that is, case 1 means: the first perception measurement entity and the second perception measurement entity The perception measurement entity establishes different perception measurement entities corresponding to the same perception measurement. "The first perception measurement establishment identification and the second perception measurement establishment identification are different" can be understood as the first perception measurement establishment and the second perception measurement establishment are different, that is, case 2 means: the first perception measurement entity and the second perception measurement entity The entity establishes corresponding different perception measurement entities for different perception measurements.

In addition, in this application, the second perception measurement entity occurs before the first perception measurement entity, and the initiating devices of the first perception measurement entity and the second perception measurement entity are both second devices.

Wherein, the initiating end devices of the first perception measurement entity and the second perception measurement entity are both second devices. It can be understood that the establishment of the first perception measurement and the establishment of the second perception measurement are initiated by the second device, that is, the establishment of the first perception measurement entity and the establishment of the second perception measurement entity are both initiated by the second device. Both the first perception measurement entity and the second perception measurement entity are trigger-based perception measurement entities.

In this application, the second device is the sensing initiator and the sensing sending end. Specifically, the second device is used to initiate the sensing process and is also used to send the PPDU for sensing measurement to the second device in the second sensing measurement entity. , such as, NDP. Correspondingly, the first device is a sensing responder and a sensing receiving end. The first device is used to participate in the sensing process initiated by the second device, and is also used to receive the PPDU used for sensing measurement in the second sensing measurement entity, such as, NDP, and perform perceptual measurements. For example, the second device may be an AP and the first device may be a STA.

Optionally, the first device may be a non-AP STA.

Optionally, in this application, it is not limited whether the first device participates in the establishment of the first perception measurement. Correspondingly, it is not limited whether the measurement and feedback of the first perception measurement entity occurs in the first device. In other words, although the second device initiates the first perception measurement establishment and the second perception measurement establishment, the second device may configure the first perception measurement establishment to the first device, or may not configure the first perception measurement establishment. Correspondingly, the first device may or may not perform measurement by the first perceptual measurement entity, which is not limited by this application.

In addition, regardless of whether the measurement of the first perception measurement entity is performed in the first device, the first device may send the perception content of the second perception measurement entity to the second device through the first perception measurement entity.

As an example, the second device may send the first information to the first device during the reporting phase of the first perception measurement entity.

The first information may be carried in a trigger frame, and the trigger frame is used to trigger the first device to feedback the sensing content.

Specifically, the trigger frame is used to trigger the first device to feed back the sensing content. Further, through the first information, the first device can be instructed to feed back the sensing content of the second sensing measurement entity.

S220: The first device sends the sensing content of the second sensing measurement entity in the first sensing measurement entity. Correspondingly, The second device receives the perception content of the second perception measurement entity from the first device in the first perception measurement entity.

Optionally, the first device sends the perception content of the second perception measurement entity in the first perception measurement entity according to the first information.

As an example, if the second device sends the first information to the first device during the reporting phase of the first perception measurement entity, then the first device may send the second information to the second device in the perception measurement report of the first perception measurement entity. Perception measures the perceived content of an entity.

Based on the solutions of the above embodiments, the second device can generate the first information, and use the first information to instruct the first device to feed back the perception content of the second perception measurement entity in the first perception measurement entity, so that the first device can use the first information to Feed back the perception content of the second perception measurement entity. Since the second perception measurement entity and the first perception measurement entity are different perception measurement entities, the first device can report the perception content based on the delayed feedback mode. Furthermore, through this feedback mode, feedback efficiency can be improved.

Optionally, in one implementation, the method 200 further includes: the first device sending the perception content of the first perception measurement entity in the first perception measurement entity.

In other words, if there is perceptual content of the first perceptual measurement entity, it can still be fed back in the first perceptual measurement entity through immediate feedback.

Optionally, in an implementation manner, if the first device receives the first information and there is sensing content of the first sensing measurement entity to be fed back, the first device may also feed back only the second sensing content according to the instructions of the first information. The sensing content of the sensing measurement entity is waited for when the second device indicates that the sensing content of the first sensing measurement entity is to be fed back before feedback is performed.

In other words, the first information may also be used to indicate changing the feedback method of the perception content of the first perception measurement entity from immediate feedback to delayed feedback.

In an implementation manner, the first information is used to indicate at least one of the following: a second perception measurement establishment identifier, a second perception measurement entity identifier, and a number of second perception measurement entities. In other words, according to at least one of the above, the first device may determine the second perception measurement entity. In other words, the first information instructs the first device to feed back the perception content of the second perception measurement entity through at least one of the above.

Optionally, the first information may be in the form of a display indication. For example, the first information may include identification information of the second perception measurement entity. That is, after the perception responder device parses the first information, it can learn the second perception measurement entity. Refers to which one or which ones.

As an example, the first information is used to instruct the first device to feed back the perception content of the second perception measurement entity, which can be implemented in the following manner.

Method A

The first information includes a second perception measurement establishment identification and a second perception measurement entity identification.

Specifically, a specific second perception measurement entity can be indicated by a second perception measurement establishment identification and a second perception measurement entity identification, that is, <measurement establishment identification, measurement entity identification>.

It should be understood that the second perception measurement establishment identification and the second perception measurement entity identification can be understood as indication group #1, and one indication group #1 is used to indicate a second perception measurement entity. When there is one second perception measurement entity, the first information may include one indication group #1. When there are multiple second perception measurement entities, the first information may include multiple indication groups #1, and each indication group #1 is used to indicate a second perception measurement entity.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. establish Mark 2 is established, and the sensing period has not been terminated in 16 links. At this time, if the sensing content of the two sensing measurement entities before link 16 has not been fed back, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in link 16. The trigger frame is used to trigger the first device. A device feeds back sensing content. The trigger frame includes first information, where the first information includes two indication groups #1. The first indication group #1 includes: a sensing measurement establishment identifier of 2 and a sensing measurement entity identifier of 2. The second indication group #1 includes: the perception measurement establishment identifier is 1 and the perception measurement entity identifier is 3. Then, the first device can determine, based on the first information, the sensing content of the sensing measurement entity that requires a sensing measurement establishment identifier of 2 and a sensing measurement entity identifier of 2, and a sensing measurement entity with a sensing measurement establishment identifier of 1 and a sensing measurement entity identifier of 3, that is, feedback. The perceptions occurring in sessions 9 and 12 measure the perceived content of the entity.

Method B

The first information includes a second perception measurement establishment identification and a first bitmap, and the first bitmap is used to indicate whether to feed back the perception content of each perception measurement entity corresponding to the second perception measurement establishment identification.

The first bitmap may also be called a perceptual measurement entity bitmap.

Specifically, the first information may include a bitmap, each bit in the bitmap corresponds to a perception measurement establishment identifier, and the value of the bit is used to indicate whether to feed back the perception content of the perception measurement entity corresponding to the perception measurement establishment identification. . For example, there are 3 perception measurement entity identifiers in total. At this time, the first bitmap may include 3 bit fields. The first bit is used to indicate whether the feedback measurement entity identifier is 1 perception content, and the second bit is used to indicate whether The feedback measurement entity identifier is 2-sensing content, and the third bit is used to indicate whether the feedback measurement entity identifier is 3-sensing content.

The second perceptual measurement establishment identifier and the first bitmap can be understood as indication group #2, and one indication group #2 is used to indicate one or more perceptual measurement entities corresponding to one perceptual measurement establishment identifier. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities are established corresponding to the same perceptual measurement, the first information may include an indication group #2. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to at least two different perceptual measurement establishments, the first information may include multiple indication groups #2, and one indication group #2 is To indicate a perception measurement, establish the perception measurement entity corresponding to the identifier.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. Identity 2 is established, and the sensing period has not been terminated in 16 links. At this time, if the sensing content of the two sensing measurement entities before link 16 has not been fed back, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in link 16. The trigger frame is used to trigger The first device feeds back sensing content. The trigger frame includes first information, where the first information includes a measurement establishment identifier of 1, a bitmap of 001, a measurement establishment identifier of 2, and a bitmap of 010. These three The bits correspond to measurement entity identifiers 1, 2, and 3 from left to right. Then, the first device may determine based on the first information that it needs to feed back the sensing content corresponding to the measurement entity with the measurement establishment identifier of 1 and the measurement entity identifier of 3, and the sensing content of the measurement entity with the sensing measurement establishment identifier of 2 and the sensing measurement entity identifier of 2, that is, The perceptions occurring in feedback sessions 9 and 12 measure the perceived content of the entity.

Method A and method B can also be understood as that the first information is used to indicate the second perception measurement establishment identification and the second perception measurement entity identification.

It should be understood that the above-mentioned methods A and B can enable the first device to clearly know the sensing content of which sensing measurement entity or entities are fed back, which is relatively more concise and flexible.

Optionally, the first information may also be in the form of an implicit indication. For example, the first information may include the number of the second perception measurement entity or the second perception measurement establishment identification corresponding to the second perception measurement entity, so that the perception responder device parse After the first information, it can be further determined which one or which second perception measurement entity refers to.

Method C

The first information includes a second perception measurement establishment identifier and the number of second perception measurement entities.

Specifically, the second device may indicate the second perceptual measurement establishment identifier and the number of the second perceptual measurement entities to the first device. Further, the first device determines the second perceptual measurement establishment identifier according to the second perceptual measurement establishment identifier and the number of the second perceptual measurement entities. Perceptual measurement entity.

As an implementation manner, the number of the second perceptual measurement entities is used to indicate N perceptual measurement entities. The N perceptual measurement entities correspond to the same perceptual measurement establishment identifier, and N is a positive integer.

It should be understood that in this manner, a default rule for the second sensing measurement entity may be preconfigured in the first device and the second device, and the default rule is used to determine the second sensing measurement entity. For example, the default rule is: sensing The measurement entity is the earliest sensing measurement entity and the sensing content has not been fed back.

The number of the second perception measurement establishment identification and the second perception measurement entity can be understood as indication group #3, and one indication group #3 is used to determine one or more perception measurement entities corresponding to one perception measurement establishment identification. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to the same perceptual measurement establishment, the first information may include an indication group #3. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to at least two different perceptual measurement establishments, the first information may include multiple indication groups #3, and one indication group #3 is To indicate a perception measurement, establish the perception measurement entity corresponding to the identifier.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. Identity 2 is established, and the sensing period has not been terminated in 16 links. At this time, if there is no feedback for the measurement establishment identifier 1, the sensing content of the measurement entity 2 and the measurement entity 3, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in step 16. The trigger The frame is used to trigger the first device to feedback perception content. The trigger frame includes first information, wherein the second perception measurement establishment identifier included in the first information is 1, the number of second perception measurement entities is 2, and the default rule is: the earliest sensing measurement entity, and the sensing content has not been fed back. Then, the first device can determine based on the first information that it needs to feed back the two sensing measurement entities corresponding to the measurement establishment identifier 1, the earliest occurrence, and the sensing content has not been fed back. The perceptual content of the perceptual measurement entity is the perceptual content of the perceptual measurement entity that occurs in feedback links 4 and 12.

Mode D

The first information includes the number of second measurement entities.

Wherein, the number of the second measurement entity is indicated by the first field, and the order of the first field in the first information is associated with the second sensing measurement establishment identification. Further, the first device determines the second perception measurement entity according to the second perception measurement establishment identifier and the number of the second perception measurement entity.

It should be understood that the first information may include multiple fields, and the order of each field in the first information is associated with a perception measurement establishment identifier. For example, there are 8 perception measurement establishment identifiers in total. At this time, the first information may include 8 fields. The first field, the second field,..., and the eighth field appear in the order of 1, 2,... respectively. , 8. Therefore, the first field, the second field,..., and the eighth field respectively correspond to the perceptual measurement establishment identifiers 1, 2,..., 8. That is, the first field is used to indicate the measurement establishment of N ₁ measurement entities with the identifier 1, and the second field is used to indicate the measurement The quantity establishes N ₂ measurement entities with the ID of 2,..., the 8th field is used to indicate the measurement establishment of N ₈ measurement entities with the ID of 8, where N ₁ , N ₂ ,..., N ₈ are all positive integer.

It should be understood that in this manner, a default rule for the second perception measurement entity may be preconfigured in the first device and the second device, and the default rule is used to determine the second perception measurement entity. For example, the default rule is: occurrence The earliest perceptual measurement entity whose perceptual content has not been fed back.

The number of the second perception measurement entities can be understood as indication group #4, and one indication group #4 is used to determine one or more perception measurement entities corresponding to a perception measurement establishment identification. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to the same perceptual measurement establishment, the first information may include an indication group #1. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to at least two different perceptual measurement establishments, the first information may include multiple indication groups #4, and one indication group #4 is To indicate a perception measurement, establish the perception measurement entity corresponding to the identifier.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. Identity 2 is established, and the sensing period has not been terminated in 16 links. At this time, if there is no feedback for the measurement establishment identifier 1, the sensing content of the measurement entity 2 and the measurement entity 3, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in step 16. The trigger The frame is used to trigger the first device to feedback sensing content. The trigger frame includes first information, where the first information includes multiple fields, and field 1 is the first field among the multiple fields. Therefore, field 1 is located The location-related measurement establishment identifier is 1, and the number of sensing measurement entities indicated by field #1 is 2. In addition, the default rule is: the sensing measurement entity that occurs earliest and whose sensing content has not been fed back. Then, the first device can determine based on the first information that it needs to feed back the sensing measurement entity that occurs earliest and whose sensing content has not been fed back corresponding to the measurement establishment identifier of 1. The perceptual content of the two perceptual measurement entities fed back is the perceptual content of the perceptual measurement entities that occurred in feedback link 4 and link 12.

Methods C and D can also be understood as that the first information is used to indicate the second perception measurement establishment identifier and the number of second perception measurement entities.

Mode E

The first information includes the number of second perception measurement entities.

The number of the second perception measurement entities is used to indicate N perception measurement entities. The N perception measurement entities are the N perception measurement entities sent before the first perception measurement entity, and N is a positive integer.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. Identity 2 is established, and the sensing period has not been terminated in 16 links. At this time, if the sensing content of the two sensing measurement entities before link 16 has not been fed back, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in link 16. The trigger frame is used to trigger The first device feeds back sensing content, and the trigger frame includes first information, where the number of sensing measurement entities indicated by the first information is 2. Additionally, the default rules are: earliest occurs, and the sensing content has not been fed back, then the first device can determine, based on the first information, the sensing content of the two sensing measurement entities that require feedback the earliest and whose sensing content has not been fed back, that is, feedback link 9 and link 12 The perception that occurs in measures the perceptual content of an entity.

Method E can also be understood as that the first information is used to indicate the number of second perception measurement entities.

Among them, in mode C, mode D, and mode E, S220, the first device sends the perception content of the second perception measurement entity, including: the first device sends the perception content of N perception measurement entities, and the N perception measurement entities Perceptual content is arranged in the order in which the perceptual measurement entities occur.

In other words, when the first device feeds back the perception content of the second perception measurement entity, it can give priority to feedback the perception content of the perception measurement entity that occurs earlier according to the order in which the perception measurement entities occur. That is, the priority order is the order in which the perception measurement entities occur. order.

Optionally, in mode C, mode D, or mode E, S220, the first device sends the perception content of the second perception measurement entity, including: the first device sends the perception content of N perception measurement entities, and the N perception measurements Among the entity's sensing contents, the sensing content of the sensing measurement entity corresponding to the first sensing measurement identifier is located at a more forward or backward position.

In other words, when feeding back the second perception measurement entity, the priority may also be to first feed back the perception measurement establishment identifier that is the same as the identity corresponding to the first perception measurement entity, and then feed back the perception measurement establishment identification that is different from the identity corresponding to the first perception measurement entity. of. Alternatively, the priority order may be to first feed back the perception measurement establishment identification that is different from the identification corresponding to the first perception measurement entity, and then feed back the perception measurement establishment identification that is the same as the identification corresponding to the first perception measurement entity.

It should be understood that the above methods C, D, and E can simultaneously instruct the first device to feed back the sensing content of multiple sensing measurement entities, which is relatively more efficient.

Mode F

The first information includes a second perception measurement establishment identification.

Specifically, the first information may include a second perception measurement establishment identification, and further, the first device may determine the second perception measurement entity according to the second perception measurement establishment identification.

In other words, in this manner, a second perception measurement establishment identifier is used to determine a second perception measurement entity.

The number of the second perception measurement entities can be understood as indication group #5, and one indication group #5 is used to determine a perception measurement entity corresponding to a perception measurement establishment identifier. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to the same perceptual measurement establishment, the first information may include an indication group #1. When there are more than one second perceptual measurement entity, and the one or more perceptual measurement entities correspond to at least two different perceptual measurement establishments, the first information may include multiple indication groups #5, and one indication group #5 is Instructing a perception measurement to establish a perception measurement entity corresponding to the identifier.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. Identity 2 is established, and the sensing period has not been terminated in 16 links. At this time, if the sensing content of the two sensing measurement entities before link 16 has not been fed back, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in link 16. The trigger frame is used to trigger The first device feeds back sensing content, and the trigger frame includes first information, where the first information includes sensing measurement establishment 1 and sensing measurement establishment identification 2. Then, the first device can It is determined based on the first information that it is necessary to feed back the sensing content of a sensing measurement entity corresponding to the measurement establishment identifier of 1, the earliest occurrence, and the sensing content has not been fed back, so as to correspond to the measurement establishment identifier of 2, the earliest occurrence, and The perceptual content of a perceptual measurement entity whose perceptual content has not been fed back, that is, the perceptual content of the perceptual measurement entity that occurred in feedback links 9 and 12.

Mode G

The first information includes a second bitmap, and one bit in the second bitmap corresponds to the second perceptual measurement establishment identifier.

The second bitmap may also be called a perceptual measurement establishment bitmap.

Specifically, the first information may be in the form of a bitmap. For example, if there are 8 measurement establishment identifiers used in the sensing process, then the second bitmap may be 8 bits, and the first bit is used to indicate whether Feedback measurement establishment of the sensing content of the sensing measurement entity with the ID of 1, the 2nd bit is used to indicate whether to feedback the sensing content of the sensing measurement entity with the ID of 2,..., the 8th bit is used to indicate whether to feed back the measurement establishment The perceptual content of the perceptual measurement entity identified as 8.

For example, on the basis of Figure 2, assume that there is a sensing period established before link 1, and the first device with AID 4 is added to the sensing period, and the sensing measurement establishment flag 1 and sensing measurement are configured for the first device. Identity 2 is established, and the sensing period has not been terminated in 16 links. At this time, if the sensing content of the two sensing measurement entities before link 16 has not been fed back, then the second device can send a trigger frame to the first device during the reporting phase of the measurement entity in link 16. The trigger frame is used to trigger The first device feeds back the sensing content, and the trigger frame includes a second bitmap, where the second bitmap is 11000000. Then, the first device may determine based on the first information that it is necessary to feed back the sensing content of a sensing measurement entity corresponding to the measurement establishment identifier of 1, the earliest occurrence, and the sensing content has not been fed back, so as to correspond to the measurement establishment identifier of 2. , the perception content of a perception measurement entity that occurs earliest and whose perception content has not been fed back, that is, the perception content of the perception measurement entity that occurs in feedback links 9 and 12.

For another example, during a sensing process, the second device can send a trigger frame to the first device during the reporting phase of the measurement entity. The trigger frame is used to trigger the first device to feedback the sensing content. The trigger frame includes the second bit. The picture is 00100010. At this time, the first device may determine that it is necessary to feed back the sensing content of a sensing measurement entity corresponding to the earliest occurrence with a measurement establishment identifier of 3, and whose sensing content has not been fed back, to correspond to the earliest occurrence of the measurement establishment identifier with 7. , and the perceptual content of a perceptual measurement entity whose perceptual content has not been fed back.

Methods F and G can also be understood as that the first information is used to indicate the second perceptual measurement establishment identification.

It should be understood that in the above various methods, the number of fields, the number of bits of the bitmap, the number of information bits, etc. are for illustration only and do not constitute a limitation on the present application.

It should be understood that the above methods F and G can achieve the indication of the second perceptual measurement entity using fewer bits, and are relatively easier to implement.

Optionally, in methods F and G, the default rule may also be: all perception measurement entities whose perception content has not been fed back. That is to say, the first device may, according to the first information, feed back the sensing content of all sensing measurement entities identified corresponding to the second sensing measurement establishment and whose sensing content has not been fed back.

Optionally, in methods F and G, the default rule may also be: determining the second perception measurement entity as one or several of all perception measurement entities whose perception content has not been fed back according to the resource size indicated in the trigger frame. That is, The first device may determine, based on the first information and the resource size indicated in the trigger frame, the sensing content of one or more sensing measurement entities that feed back the corresponding measurement establishment identification.

Mode H,

The second perception measurement entity is a perception measurement entity that occurs earliest and whose perception content has not been fed back. The first information is used to indicate whether to feed back the perception content of the second perception measurement entity.

Specifically, a default rule for the second perception measurement entity may be preconfigured in the first device and the second device. The default rule is used to determine the second perception measurement entity. For example, the default rule is: the earliest occurrence, and the perception content is not A sensory measurement entity that is fed back. At this time, the first information may be 1 bit, and a value of the 1 bit may be used to indicate the sensing content of a sensing measurement entity whose feedback occurs earliest and whose sensing content has not been fed back.

Method I.

The second perceptual measurement entities are all perceptual measurement entities measured by the first device and whose perceptual content has not been fed back. The first information is used to indicate whether the first device feeds back the perceptual content of the second perceptual measurement entity.

Specifically, a default rule for the second perception measurement entity may be preconfigured in the first device and the second device. The default rule is used to determine the second perception measurement entity. For example, the default rule is: measured by the first device, and All perceptual measurement entities whose perceptual content is not fed back. At this time, the first information may be 1 bit, and a value of the 1 bit may be used to indicate feedback of the sensing content of all sensing measurement entities measured by the first device and whose sensing content is not fed back.

At this time, the first device may feed back the sensing content of all sensing measurement entities whose sensing content has not been fed back as much as possible according to the first information and the resource size indicated in the trigger frame.

Method J.

When it is difficult to fully feedback the sensory content corresponding to a certain measurement entity in one feedback, segmented feedback can be used to inform, that is, the second sensory measurement entity can be segmented, and a lower level than the measurement entity can be added. Granularity, for example, the granularity is Segment. As an example, the sensing content of measurement entity 1 can be divided into 10 fragments, namely fragment 1, fragment 2, ..., fragment 10, and the first information can instruct the first device to feedback fragment 1 and fragment 2. and the perceived content of shard 3.

Optionally, in one implementation, the method 200 further includes: the first device sending second information, the second information being used to indicate the second perception measurement entity.

It should be understood that the second information is used to indicate the second perception measurement entity. It can also be said that the second information is used to identify the second perception measurement entity, or the second information is used to identify the second perception measurement entity. In other words, the second device can determine which one or which second perception measurement entity refers to based on the second information.

As an example, the specific way in which the second information is used to indicate the second perception measurement entity can refer to the upper-level ways A to J, or it can be a combination of any two or more ways, which will not be described again here.

Specifically, the first device may send the second information to the second device in the first perception measurement entity, so as to indicate the second perception measurement entity.

The fourth information can also be understood as being used to indicate whether the perceptual content of the second perceptual measurement entity can be fed back through delayed feedback across identifiers, or used to indicate whether the perceptual content of the second perceptual measurement entity can be fed back through non-identity delay feedback. Feedback via delayed feedback across identities. That is, the fourth information is used to indicate whether the perception content of the second perception measurement entity indicates feedback in other perception measurement entities.

For example, when sending the trigger frame of the second perception measurement entity, or before sending the trigger frame, the second device may indicate to the first device whether the perception content of the second perception measurement entity supports feedback in the first perception measurement entity.

As an example, the fourth information may be 1 bit, and the two values of this 1 bit respectively indicate that the perception content of the second perception measurement entity supports feedback in the first perception measurement entity, and the perception content of the second perception measurement entity does not support Feedback in the first perceptual measurement entity.

Secondary perception measures the perceived content of the entity.

As an example, the fifth information may be 1 bit, and the two values of the 1 bit respectively indicate that the first device supports feedback of the perception content of the second perception measurement entity in the first perception measurement entity, and the first device does not support feedback in the first perception measurement entity.

Perceptual content, that is, whether it only includes perceptual content that is fed back through immediate feedback.

Specifically, if the ninth information indicates that the first perception measurement entity includes the perception content of the second perception measurement entity, then the first device may feed back the perception of the second perception measurement entity in the manner described in method 200 or method 300 of this application. content. If the ninth information indicates that the first perception measurement entity does not include the perception content of the second perception measurement entity, then the first device may report only the perception content of the first perception measurement entity in the first perception measurement entity.

The sixth information and the ninth information may be sent before S220, or may be sent in the first perception measurement entity together with the perception content of the second perception measurement entity in S220.

Optionally, if the first device supports delayed feedback across identities, and the first device is not configured with the first sensing measurement establishment, that is, the first sensing measurement establishment identity is an identity that the first device has not established with the second device, then in Before S210, when the first device reads the trigger frame in the polling phase in the first perception measurement entity, it still needs to read the information corresponding to the first perception measurement establishment identifier, so as to know whether it needs to perform the first perception measurement establishment identification in the first perception measurement entity.

Specifically, during the negotiation phase or the second sensing measurement establishment phase, the first device indicates to the second device the size of the available storage space of the first device. For sensing content that exceeds the storage space, the first device will discard the earliest stored content. Sense content is stored to satisfy the latest acquired sense content.

The available storage space may be the number of available storage space bits, the number of storable sensing contents, etc. The number may be in units of sensing measurement entities, that is, one sensing content refers to the sensing content of one sensing measurement entity.

Optionally, for the perception content of the third perception measurement entity, if the second device instructs the first device to feedback the perception content of the second perception measurement entity through the first information, and the second perception measurement entity includes the third perception measurement entity, that is, If the sensing content of the third sensing measurement entity is still triggered by the second device after being discarded, the first device can indicate it in the first sensing measurement entity by "(Invalid)" or "(Deleted)" This third perception measures the state of the entity's perception content.

In addition, if the first device supports cross-identity delayed feedback, then after a certain perception measurement establishment is terminated, the perception content of the perception measurement entity corresponding to the perception measurement establishment identification can be retained so that it can be used in other perception measurements. Establish feedback in the perception measurement entity corresponding to the identification.

In addition, the eighth information may also be used to instruct the second device to discard the sensing content of the third sensing measurement entity if feedback is not triggered in the next sensing measurement entity, so that the second device can perform the sensing content in the next sensing measurement entity. The sensing content of the third sensing measurement entity is prioritized for triggering feedback.

The seventh information and/or the eighth information may be carried in a certain perception measurement entity, for example, in a perception measurement report frame sent by the first device to the second device.

S310: The second device sends a trigger frame to the first device in the first perception measurement entity, and accordingly, the first device receives the trigger frame.

As an example, the second device may send a trigger frame to the first device during the reporting phase of the first perception measurement entity.

The trigger frame is used to trigger the first device to feedback the sensing content.

Specifically, the description of the first device, the second device, and the trigger frame may refer to the above method 200. The difference is that the trigger frame in method 300 does not include the first information.

S320: The first device sends the second information and the perception content of the second perception measurement entity to the second device in the first perception measurement entity. Correspondingly, the second device receives the second information and the perception content of the second perception measurement entity from the first device in the first perception measurement entity.

Optionally, the first device sends the perception information of the second perception measurement entity in the first perception measurement entity according to the trigger frame. Allow.

The first perception measurement entity and the second perception measurement entity are different perception measurement entities, and the initiating devices of the first perception measurement entity and the second perception measurement entity are both second devices.

Specifically, the understanding and understanding of "the first perception measurement entity and the second perception measurement entity are different perception measurement entities" and "the initiating end devices of the first perception measurement entity and the second perception measurement entity are both second devices" For instructions, please refer to method 200 above, and will not be described again here.

Wherein, the second information is used to indicate the second perception measurement entity.

Specifically, for an understanding and description of "the second information is used to indicate the second perception measurement entity", please refer to the above method 200, which will not be described again here.

Based on the solutions of the above embodiments, the first device can feed back the sensing content of the second sensing measurement entity to the second device based on the trigger frame in the first sensing measurement entity, and indicate to the second device which second sensing measurement entity is specific. Or, since the second perception measurement entity and the first perception measurement entity are different perception measurement entities, the first device can report the perception content based on the delayed feedback mode. Furthermore, through this feedback mode, feedback efficiency can be improved.

In one implementation, the method 300 further includes: the first device determines whether to feed back the perception content of the second perception measurement entity according to the feedback mode of the first device and the size of the transmission resource allocated in the trigger frame.

Specifically, the feedback mode of the first device includes delayed feedback and immediate feedback. The feedback mode of the first device may be determined through negotiation between the first device and the second device during the second sensing measurement establishment phase, or may be determined in other ways or at other stages.

The first device may determine whether to feed back the sensing content of the second sensing measurement entity according to the feedback mode and the size of the transmission resource allocated in the trigger frame. If the feedback mode is delayed feedback, the first device sends feedback to the second sensing measurement entity in the first sensing measurement entity. The device sends the sensing content of the second sensing measurement entity. If the feedback mode is immediate feedback, the first device may determine to feed back the sensing content of the first sensing measurement entity. Further, the first device may also determine whether to feed back the sensing content of the second sensing measurement entity based on the size of the transmission resources allocated in the trigger frame. , if the transmission resources are sufficient, the perception content of the first perception measurement entity and the perception content of the second perception measurement entity can be fed back. If the transmission resources are insufficient to feed back the perception content of the first perception measurement entity and the perception content of the second perception measurement entity, Then the first device may only feed back the perception content of the first perception measurement entity, but not the perception content of the second perception measurement entity. In other words, if the feedback mode is immediate feedback, the first device can further determine whether to feedback the perceptual content of the second perceptual measurement entity based on feedback of the perceptual content of the first perceptual measurement entity, that is, the perceptual content of the first perceptual measurement entity has a higher High priority.

Optionally, as an implementation manner, in any embodiment of the present application, after the feedback of the perception content of the second perception measurement entity is completed, the second perception measurement can be reused under the second perception measurement establishment flag. The ID of the entity. For example, if the sensing content of the measurement entity identification ID is always fed back through immediate feedback, then the measurement entity ID can always be reused without causing misunderstanding. If the measurements in a measurement entity correspond to delayed feedback from at least one user, the ID cannot be reused before these delayed feedbacks are completed.

Optionally, there is also a two-stage feedback (such as threshold-based feedback) in the current 802.11bf standard. That is, during the reporting stage, the second device can decide whether to respond based on the feedback of the first device in the first stage of reporting. Triggers feedback from the first device in the second phase. One example is that if the CSI change degree is greater than a certain threshold, the second stage of feedback is triggered, and vice versa, there is no need to trigger the second stage of feedback.

The method 200 and the method 200 described in this application are also applicable to this two-stage feedback, that is, the first stage of the report can be used with the first stage of the report of other measurement entities. Similarly, the second stage can be and other measurements The second stage of the entity's reporting uses the methodology of this application.

In addition, since the first device needs to decide whether to trigger the second stage of feedback based on the content in the first stage of the report, for the measurement results of the same perception measurement entity, the content of the first stage should take precedence over the second stage feedback, for example Say, when the first stage is delayed feedback, the second stage cannot be immediate feedback.

Optionally, in this application, some instances of the same configuration (that is, the same Measurement setup ID) provide delayed feedback, and some instances provide immediate feedback. At this time, if there are measurement results corresponding to the same setup ID, the unfeedback measurement results of the setup ID corresponding to the measurement instance can be given priority.
