Generally, the wireless sensing process includes negotiation, measurement, reporting (or not) and other stages, after the initiator and the responder of the wireless sensing process negotiate the roles, parameters and the like of wireless sensing signal transmission and reception in the negotiation stage, if both sides accept to execute the wireless sensing process, then the wireless sensing process is started, otherwise, the negotiation is carried out again; and then forming a report by the measurement results, and terminating wireless perception after all the measurement results are interacted. One wireless awareness process may conduct one or more wireless awareness measurement processes, each of which may include one or more measurement instances. One measurement instance may include a measurement polling phase for querying the terminal whether the measurement can currently be performed, a measurement probing phase for entering the measurement probing phase only if the terminal can currently perform the measurement, and a measurement reporting phase (optional). In the measurement detection stage, a sender of the wireless sensing signal sends the wireless sensing signal to a receiver of the wireless sensing signal, and after the receiver receives the wireless sensing signal, the receiver measures a wireless channel according to the received wireless sensing signal. In the measurement report stage, the receiver of the wireless sensing signal generates a measurement report according to the measurement result and can also send the measurement report out.
In the embodiment of the present application, it is assumed that the access point AP1 establishes connection with 3 terminals, i.e., STA1, STA2 and STA3, as shown in fig. 1, where the APs, STA1-3 (i.e., STA1, STA2 and STA 3) all have wireless sensing capability, and the APs can exchange wireless sensing capability information with the terminals STA 1-3. It should be noted that in the embodiment of the present application, there may be fewer or more terminals, for example, 1 terminal, 2 terminals, 6 terminals, etc., and the number of the terminals is not limited in the embodiment of the present application. The access point is one of the access devices, and the access device may also be other devices such as a router, and in the embodiment of the present application, the access point is only taken as an example for describing in detail, but the embodiment of the present application is not limited to the access point.
When STA1 needs to perform the wireless sensing service, STA1 requests AP1 to perform the wireless sensing process. Specifically, STA1 may send a message to AP1 containing an indication requesting to establish a wireless awareness process; after receiving the message, the AP1 sends a response message containing an indication of whether to agree to establish a wireless sensing process to the STA1, and negotiates the wireless sensing process with the STA2 and the STA3, and it should be noted that the sequence of the two steps of sending the response message to the STA1 and negotiating the wireless sensing process with the AP1, the STA2 and the STA3 by the AP1 can be adjusted as required; in the embodiment of the application, assuming that the STA2 and the STA3 agree to execute the wireless sensing process, the AP1, the STA2 and the STA3 establish the wireless sensing process; the AP1 establishes a wireless sensing measurement process with the STA1, the STA2 and the STA 3; AP1 performs wireless sensing measurements with STA1, STA2, and STA 3.
In a specific embodiment, the STA1 requests the AP1 to perform the wireless sensing procedure includes the following steps:
s101.sta1 sends a aware session request message (e.g. sensing session request message) to AP1, indicating a request to establish a wireless aware process.
S102.ap1 sends a sensing setup request message (such as sensing setup request message) to STA2 and STA3, and receives sensing setup response messages (such as sensing setup response message) sent by STA2 and STA3, where the sensing setup request message indicates that a wireless sensing process is requested to be set up, and the sensing setup response message indicates whether the wireless sensing process is agreed to be set up.
S103.ap1 sends a sensing session response message (e.g. sensing session response message) to STA1, where the sensing session response message indicates whether to agree to establish a wireless sensing procedure.
Through steps S101-S103, AP1 establishes a wireless awareness process with STA1, STA2, and STA 3. In steps S101-S103, the awareness session request message and the awareness establishment request message may be the same message, and the awareness session response message and the awareness establishment response message may be the same message. In other embodiments, STA1 may also establish a wireless awareness process with AP1 through a connection request message (e.g., association request message) or the like.
S104.ap1 sends a measurement setup request message (e.g. measurement setup request message) to STA1, STA2 and STA3, where the measurement setup request message contains parameters shown in table 1.
TABLE 1
| Parameters (parameters) | Description of the invention |
| Measurement setup ID | Identification of wireless-aware measurement processes |
| Measurement config | Configuration parameters for wireless awareness measurement |
S105.STA1, STA2 and STA3 send measurement setup response messages (e.g. measurement setup response messages) to AP1, wherein the measurement setup response messages contain the parameters shown in table 2.
TABLE 2
| Parameters (parameters) | Description of the invention |
| Measurement setup ID | Identification of wireless-aware measurement processes |
| Measurement config | Optionally, configuration parameters for wireless-aware measurement |
| AP-to-NonAPReport | Indicating whether AP1 is required to transmit the measurement result |
| Status code | Indicating whether or not to grant the request |
In the embodiment of the present application, it is assumed that all terminals agree to establish a wireless sensing measurement procedure, and the Status code value is set to SUCCESS, that is, a request is indicated to agree, and in actual deployment, if a terminal does not agree to participate in wireless sensing measurement, the Status code value is set to other values, and the request is indicated to disagree. In the embodiment of the application, the value of the AP-to-NonAPPReport is set to 1 in the measurement setup response message sent by the STA1, which means that the AP1 is required to send the measurement result to the STA1; setting the value of AP-to-NonAPPReport to 0 in the measurement setup response message sent by STA2, which means that the AP1 is not required to send the measurement result to STA2; the value of AP-to-nonaPReport is set to 0 in the measurement setup response message sent by STA3, indicating that AP1 is not required to send the measurement result to STA3. In other embodiments, STA2 may also set the value of AP-to-nonaPReport in the measurement setup response message to 1 as needed, indicating that AP1 is required to send the measurement result to STA2; STA3 may also set the value of AP-to-nonaPReport in the measurement setup response message to 1 as needed, indicating that AP1 is needed to send the measurement result to STA3.
Thus, AP1 establishes a wireless awareness measurement procedure with STA1, STA2, and STA 3. It should be noted that the measurement setup request message in step S104 and the measurement setup response message in step S105 may be other types of messages as long as the wireless sensing measurement procedure can be established. In other embodiments, the establishment of the wireless sensing measurement process may also be included in the establishment of the wireless sensing process, for example, the wireless sensing process and the wireless sensing measurement process are established simultaneously through steps S101-S103, where the sensing session request message may include role information of the wireless sensing process, configuration parameters of the wireless sensing measurement, and the like; the sensing establishment request message may include an identifier of a wireless sensing measurement process, role information of the wireless sensing process, and a measurement parameter of the wireless sensing process, optionally, the sensing establishment request message may further include transmission resource information, where the transmission resource information is used to instruct a terminal to transmit a resource unit used by a wireless sensing data packet; the awareness session response message may include an identifier of the wireless awareness measurement process, role information of the wireless awareness process, configuration parameters of the wireless awareness measurement, and the like.
S106.ap1, STA2, STA3 start performing a sensing measurement according to parameters negotiated by the measurement setup request message and the measurement setup response message.
S107.ap1 obtains a wireless sensing measurement result, and sends the measurement result to STA1.
In the wireless sensing process, STA1, STA2, STA3 and AP1 all maintain respective wireless sensing process information, where the wireless sensing process information maintained by STA1 is shown in table 3.
TABLE 3 Table 3
| Sensing session ID | Measurement setup ID | Measurement instance ID |
| Address of AP1 | 1 | 1 |
| Address of AP1 | 1 | 2 |
The wireless sensing procedure information maintained by STA2 and STA3 may refer to the wireless sensing procedure information of STA1.
The wireless awareness process information maintained by AP1 is shown in table 4.
TABLE 4 Table 4
In tables 3 and 4, sensing session ID represents the identity of the wireless awareness process; measurement setup ID the identity of a wireless-aware measurement process; measurement instance ID the identity of the measurement instance; the AID is a connection identifier allocated to the terminal by the access point when the terminal establishes a connection with the access point.
The above is an exemplary description when STA1 needs to perform wireless awareness services. When the STA2 also needs to perform the wireless sensing service, it may perform wireless sensing measurement according to the flow shown in fig. 2, which specifically includes:
STA2 checks if it has an established wireless sensing measurement procedure.
2.1 if there is no established wireless sensing measurement procedure, then establishing a wireless sensing measurement procedure with access point AP1 and indicating that AP1 is required to send the measurement result of the established wireless sensing measurement procedure to itself, namely STA2.
In some embodiments, STA2 may send a message to AP1 containing an indication that AP1 needs to send a measurement result and configuration parameters of the wireless sensing measurement, and receive a response message from AP1, where the response message contains an identification of the wireless sensing measurement procedure and an indication of whether to agree to establish the wireless sensing measurement procedure. In a specific embodiment, STA2 sends measurement setup request a message to AP1, where the message includes configuration parameters and parameters of the wireless sensing measurement AP-to-nanapreport, and sets the value of AP-to-nanapreport to 1, which indicates that AP1 is required to send the measurement result to itself, i.e., STA2.
In other embodiments, the STA2 may also establish the wireless sensing measurement procedure through the steps of establishing the wireless sensing measurement procedure by the STA1, and specifically refer to steps S101-S105, which will not be described in detail herein.
2.2 if there is an established wireless sensing measurement procedure, and there is a measurement parameter configured by the established wireless sensing measurement procedure that meets the requirement (i.e. a result required by the sensing service can be obtained according to a measurement result obtained by measuring the configuration parameter of the current wireless sensing measurement), STA2 requests access point AP1 to send a measurement result of a first wireless sensing measurement procedure, where the first wireless sensing measurement procedure is the established wireless sensing measurement procedure whose configured measurement parameter meets the requirement.
For example, STA2 sends a measurement setup update message (e.g. measurement setup update message) to AP1, which includes a parameter Measurement setup ID, a value set to the identity of the established wireless sensing measurement process for which the configured measurement parameters meet the requirements, and a parameter AP-to-nanapreport, and a value set to 1, indicating that AP1 is required to send the measurement result to itself, i.e. STA2.
2.3 if there is an established wireless sensing measurement process, but the measurement parameters configured by the established wireless sensing measurement process do not meet the requirement, then STA2 and access point AP1 establish the wireless sensing measurement process and instruct AP1 to send the measurement result of the established wireless sensing measurement process to itself, namely STA2, and the process is the same as step 2.1, and will not be repeated here; or STA2 requests access point AP1 to adjust the measurement parameters configured by the second wireless sensing measurement process, and instructs AP1 to send the measurement result of the second wireless sensing measurement process to itself, namely STA2, where the second wireless sensing measurement process is an established wireless sensing measurement process where the configured measurement parameters do not meet the requirement, and STA2 sends a measurement setup update message (e.g. measurement setup update message) to AP1 to adjust the configuration parameters of the wireless sensing measurement to meet the requirement of wireless sensing service, where the message includes the identification of the wireless sensing measurement process to be adjusted and the configuration parameters of the modified wireless sensing measurement, and the parameter AP-to-nonapriort, and sets its value to 1, which indicates that AP1 is required to send the measurement result to itself, namely STA2.
After receiving the message sent by the STA2, the AP1 establishes a wireless sensing measurement process according to the received message and sends a measurement result to the STA2; or sending the measurement result of the corresponding wireless sensing measurement process to the STA2 according to the received message; or adjusting measurement parameters configured by the corresponding wireless sensing measurement process according to the received message, and sending the measurement result to the STA2. For example, after receiving the measurement setup request message sent by STA2, AP1 establishes a new wireless sensing measurement procedure and sends the measurement result to STA2; or after receiving the measurement setup update message sent by the STA2, the AP1 sends a measurement result of the wireless sensing measurement process indicated by Measurement setup ID to the STA2 according to the parameter Measurement setup ID and the value of the AP-to-nonaPReport contained in the message, if the value of the AP-to-nonaPReport is 1. It should be noted that, in the embodiment of the present application, the measurement result may be measured original channel information, or may be a wireless sensing result calculated according to the original channel information.
