Generally, the wireless sensing process includes negotiation, measurement, reporting (or not) and termination, after the initiator and the responder of the wireless sensing process negotiate the roles, parameters and the like of sending and receiving wireless sensing signals in the negotiation stage, if both sides accept to execute the wireless sensing process, the wireless sensing process starts to be executed, otherwise, the negotiation is carried out again, then the measurement results are formed into a report, and the wireless sensing is terminated after all the measurement results are interacted. One wireless awareness process may conduct one or more measurement processes, each of which may include one or more measurement instances. One measurement example typically includes a measurement polling phase for querying whether the terminal can currently perform a wireless sensing process, a measurement probing phase for entering the measurement probing phase only when the terminal can currently perform the wireless sensing process, and a measurement reporting phase (optional), otherwise, entering the next query. 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. When the wireless sensing needs to be terminated, the whole wireless sensing process may need to be terminated, one or more measurement processes in the wireless sensing process may need to be terminated, or only one or more measurement instances in one measurement process may need to be terminated.

In the embodiment of the present application, it is assumed that an access point AP establishes connection with 3 terminals, namely STA1, STA2 and STA3, wherein the AP, STA1-3 (namely STA1, STA2 and STA 3) all have wireless sensing capability, and the AP 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.

The manner in which the AP establishes a connection with the terminal STA1-3 includes, for example, the following steps:

and S001, the AP sends a broadcast message (such as a beacon message) in a broadcast mode, and the broadcast message carries wireless sensing capability information supported by the AP.

And S002. The STA receives the broadcast message sent by the AP and reads the wireless sensing capability information supported by the AP.

S003.sta1 sends a connection request message (e.g., association request message) to the AP requesting connection to the AP, and includes wireless awareness information supported by STA1 in the connection request message.

S004. the ap receives the connection request message sent by STA1, and sends a connection response message (e.g. association response message) to STA1, where the connection response message indicates whether to agree to establish a connection.

S005.STA1 receives the connection response message sent by the AP, and if the message indicates that the connection establishment is agreed, the connection is established with the AP.

Both STA2 and STA3 establish a connection with the AP according to steps S001-S005.

After the STA1-3 establishes connection with the AP, wireless sensing service can be performed. Fig. 1 is a flowchart of a wireless sensing method according to an embodiment of the present application. As shown in fig. 1, the wireless awareness includes the following:

s101, the access point negotiates with the terminal and establishes a wireless sensing process.

1) When the access point AP is acting as an initiator of the wireless awareness process, the negotiation process includes:

s1101, the AP sends a perception establishment request message (such as sensing setup request message) to the STA1-3, wherein the perception establishment request message contains wireless perception process role information, measurement configuration parameters and wireless perception identification. Optionally, the wireless sensing identifier includes at least one of a wireless sensing process identifier, a measurement process identifier and a measurement instance identifier, where the wireless sensing process identifier is used to identify a wireless sensing process, the measurement process identifier is used to identify a wireless sensing measurement process in the wireless sensing process, and the measurement instance identifier is used to identify a measurement instance in the wireless sensing measurement process. For example, the wireless awareness identifier includes a wireless awareness process identifier, the wireless awareness process identifier in the awareness establishment request message sent to STA1 by the AP is set to 1, the wireless awareness process identifier in the awareness establishment request message sent to STA2 is set to 2, the wireless awareness process identifier in the awareness establishment request message sent to STA3 is set to 3, which means that the AP requests STA1, STA2 and STA3 to perform different wireless awareness processes with wireless awareness process identifiers of 1,2 and 3, respectively, and the AP may also request STA1, STA2 and STA3 to perform the same wireless awareness process at the same time, and at this time, the AP may set the wireless awareness process identifier in the awareness establishment request message sent to STA1-3 to the same value (e.g. 1). As another example, the wireless sensing identifier includes a wireless sensing process identifier and a measurement process identifier, for example, if the wireless sensing process identifier in the sensing establishment request message sent to the STA1 is set to 1, the measurement process identifier is set to 1-3, and the wireless sensing process indicating that the wireless sensing process identifier 1 executed by the requesting STA1 may include 3 measurement processes with measurement process identifiers of 1-3; as another example, the wireless sensing identifier further includes a measurement instance identifier, e.g., the measurement instance identifier in the sensing establishment request message sent to STA1 is set to 1-3, indicating that 3 measurement instances with measurement instance identifiers of 1-3 may be included in the wireless sensing procedure performed by the requesting STA 1. As another example, the wireless awareness identifier includes a wireless awareness process identifier, a measurement process identifier and a measurement instance identifier at the same time, for example, the wireless awareness process identifier in the awareness establishment request message sent to the STA1 is set to 1, the measurement process identifier is set to 1-3, the measurement instance identifier corresponding to the measurement process identifier 1 is set to 1-2, the measurement instance identifier corresponding to the measurement process identifier 2 is set to 3-5, the measurement instance identifier corresponding to the measurement process identifier 3 is set to 6, 3 measurement processes with measurement process identifiers 1-3 may be included in the wireless awareness process indicating that the wireless awareness process identifier 1 is executed by the requesting STA1, and the measurement process with measurement process identifier 1 may include 2 measurement instances with measurement instance identifiers 1-2, the measurement process with measurement process identifier 2 may include 3 measurement instances with measurement instance identifiers 3-5, and the measurement process with measurement process identifier 3 may include 1 measurement instance with measurement instance identifier 6. It should be noted that, the wireless awareness identifier in the awareness establishing request message may include any one or more of a wireless awareness process identifier, a measurement process identifier and a measurement instance identifier, for example, include only a measurement process identifier (the measurement process identifier may uniquely indicate a wireless awareness measurement process), or include only a measurement instance identifier (the measurement instance identifier may uniquely indicate a measurement instance), or include a measurement process identifier and a measurement instance identifier, or include a wireless awareness process identifier and a measurement instance identifier.

Optionally, the role information of the wireless sensing process may include an address or an identifier of a sender of the wireless sensing signal in the wireless sensing process and an address or an identifier of a receiver of the wireless sensing signal in the wireless sensing process, and may also include a role of a responder, or include a role of a responder and an address or an identifier of a responder, which is not limited in the embodiment of the present application.

S1102. After STA1-3 receives the request message for sensing establishment, if the request message for sensing establishment includes wireless sensing identification, then the wireless sensing identification is stored, if the request message for sensing establishment is accepted to execute the wireless sensing process, then the parameter status code value is set to SUCCESS, otherwise, the parameter is set to be returned, and STA1-3 includes the status code parameter in the message for sensing establishment response (such as sensing setup response message) and sends the message to AP. Optionally, the wireless sensing identifier may also be included in the sensing setup response message, and the value of the wireless sensing identifier is the same as that of the wireless sensing identifier in the received sensing setup request message.

After receiving the sensing establishment response message, the ap takes the terminal whose parameter status code value in the sensing establishment response message is SUCCESS as a responder, and in this embodiment of the present application, assuming that the status code values in the sensing establishment response messages of STA1, STA2 and STA3 are both SUCCESS, STA1, STA2 and STA3 are taken as responders in the wireless sensing process.

2) When the access point AP is acting as a responder to the wireless sensing process, in some embodiments, the STAs 1-3 may each be an initiator of the wireless sensing process, and initiate different wireless sensing processes respectively, where the negotiation process includes:

s1201.sta1-3 sends a awareness establishment request message (e.g. sensing setup request message) to the AP, where the awareness establishment request message includes the requested wireless awareness process role information and measurement configuration parameters.

S1202. After receiving the sensing establishment request message, the AP in the embodiment of the application assumes that the AP accepts the sensing establishment requests of the STA1, the STA2 and the STA3, and then the AP sends a sensing establishment response message to the STA1, the STA2 and the STA3, wherein the sensing establishment response message indicates whether to accept to execute the wireless sensing process or not and comprises role information of the wireless sensing process, measurement configuration parameters and wireless sensing identification. The setting of the wireless sensing identifier in the sensing setup response message in step S1202 may refer to the setting of the wireless sensing identifier in the sensing setup request message in step S1101, and will not be described herein.

In other embodiments, a terminal (e.g., STA 1) may be used as an initiator to initiate a wireless sensing process, where the AP and the other terminals (e.g., STA2 and STA 3) are both responders to the wireless sensing process, and the AP needs to negotiate a wireless sensing process with STA1 as the initiator and negotiate a wireless sensing process with STA2 and STA3, and the negotiation process with STA1 may refer to steps S1201-S1202, and the negotiation process with STA2 and STA3 may refer to steps S1101-S1103, which are not repeated herein, but the wireless sensing process identifier in the sensing setup response message sent by the AP to STA1 is the same as the value of the wireless sensing process identifier in the sensing setup request message sent by the AP to STA2 and STA3 (e.g., both set to 1), and the measurement process identifier and the measurement instance identifier may be different. The embodiment of the present application assumes that the AP accepts the wireless sensing procedure requested by STA1, and that both STA2 and STA3 accept to perform the wireless sensing procedure.

And S102, the access point and the terminal execute wireless sensing measurement. Illustratively, the wireless awareness measurement includes the steps of:

s2001. the ap sends a trigger message (such as a trigger frame message) to STA1, STA2 and STA3, where the trigger message includes a trigger type, and the trigger type is set to indicate that the current trigger message is used for wireless sensing process polling.

For example, the AP sends a trigger frame message to STA1, STA2 and STA3, where the message includes a parameter type (for indicating the type of the trigger message) and a subtype (for indicating the subtype of the trigger message), and the parameter type and subtype combine to determine the type of the trigger frame message, e.g., where the type value is set to "send" and the subtype value is set to "poll" to indicate that the current trigger message is used for wireless sensing process polling. Illustratively, the parameters contained in the trigger frame message are shown in Table 1.

TABLE 1

The user info contains parameters shown in Table 2. If the user info1 contains the AID of STA1, the user info2 contains the AID of STA2, and the user info3 contains the AID of STA 3.

TABLE 2

Optionally, the trigger message may further include a wireless sensing identifier, for example, a measurement instance identifier (a measurement instance identifier may be a unique identifier of a measurement instance) for identifying the measurement instance, and may also include a wireless sensing process identifier and/or a measurement process identifier, where the setting of the wireless sensing identifier in the trigger message may refer to a sensing establishment response message or a setting of the wireless sensing identifier in a sensing establishment request message sent by the AP to the terminal in step S101, which is not described herein. It should be noted that, the trigger message may include a wireless sensing identifier with one of the sensing establishment response message or the sensing establishment request message sent by the AP to the terminal in step S101 (or may include both the wireless sensing identifier, for example, the sensing establishment response message or the sensing establishment request message sent by the AP to the terminal in step S101 includes a wireless sensing process identifier, and the trigger message includes a measurement process identifier and a measurement instance identifier). The terminal can store the received wireless sensing identifier.

S2002.STA1, STA2 or STA3, after receiving the trigger message, sends a first message to the AP, where the first message indicates whether a wireless sensing procedure can be performed.

For example, after receiving the trigger frame message by STA1, STA2 or STA3, if the type value in the message is sending, the subtype value is poll, and the message includes an AID of the user (including terminal information in the trigger message), the embodiment of the present application assumes that STA1 and STA2 can currently perform the wireless sensing procedure, and STA3 cannot currently perform the wireless sensing procedure, and STA1 and STA2 send CTS to self (can send) messages for indicating that the wireless sensing procedure can be performed. The second message may also be other types of messages other than CTS to self messages, where a set parameter or the like indicates whether the wireless sensing process can be executed, and the STA3 needs to send a response message to the AP, which is not limited in this embodiment of the present application.

1) When the access point and the terminal negotiate to determine that the access point AP is the sender of the wireless sense signal in the wireless sense process in step S101, the wireless sense measurement further includes:

s2013. after receiving the CTS to self messages of STA1 and STA2, the AP sends NDPA messages (null data packet notification messages) to STA1 and STA2, where the NDPA messages are used to indicate that the AP is about to send a wireless sensing signal, and the wireless sensing signal may be NDP (null data packet). After waiting for SIFS (short interframe space) duration, the AP transmits NDP (null data packet, i.e., wireless sense signal in the present application).

S2014.STA1 or STA2 starts to receive the NDP at the interval SIFS after receiving the NDPA message, and measures the wireless channel according to the received NDP.

S2015. if the AP needs the terminal to feed back the measurement result, sending a trigger message to STA1 and STA2, where the trigger message includes a trigger type, and the trigger type in the trigger message is set to indicate that the current trigger message is used for requesting a measurement report.

For example, the AP sends a trigger frame message to STA1 and STA2, where the message includes parameters type and subtype, and the parameters type and subtype combine to determine the type of trigger frame, e.g., where the type value is set to "send" and the subtype value is set to "report", which indicates that the current trigger message is used to request a measurement report.

After STA1 or STA2 receives the trigger frame message, if the type value in the message is sending, the subtype value is report, the message contains its AID (the trigger message contains terminal information), and STA1 and STA2 have already finished wireless sensing measurement report currently, STA1 and STA2 send measurement report to the AP.

2) When the access point and the terminal negotiate to determine that the access point AP is the receiver of the wireless sense signal in the wireless sense process in step S101, the wireless sense measurement further includes:

And S2023, the AP sends trigger messages to the STA1 and the STA2, wherein the trigger messages comprise trigger types, and the trigger types in the trigger messages are set to indicate that the current trigger messages are used for indicating the terminal to send wireless sensing signals.

For example, the AP sends a trigger frame message to STA1 and STA2, where the message includes parameters type and subtype, and the parameters type and subtype combine to determine the type of the trigger frame, e.g., where the type value is set to "sending" and the subtype value is set to "sounding", which indicates that the current trigger message is used to instruct the terminal to send a wireless sensing signal.

After receiving the trigger frame message, STA1 or STA2 sends NDP (i.e. wireless sensing signal) to the AP after receiving the duration of the message interval SIFS if the type value in the message is sensing and the subtype value is sounding and the message contains its AID (the trigger message contains terminal information).

S2025.Ap receives NDP and measures the wireless channel with STA1 and STA 2.

When the wireless sensing needs to be terminated, in some embodiments, the AP may send a trigger message (such as a trigger frame message) to STA1 and STA2, where the trigger message includes a trigger type, one or more pieces of terminal information, and an identifier of an object to be terminated, and the trigger type in the trigger message is set to indicate that the wireless sensing is terminated. Illustratively, the trigger message includes parameters shown in table 3.
