In particular, when a person is in a space surrounded by a wireless signal, the propagation of the wireless signal is inevitably affected.

The wireless Sensing (Sensing) technology is a wireless Sensing method for multiplexing wireless signals existing in the environment, analyzing the change of the wireless signals in the propagation process, and obtaining the characteristics of a signal propagation space (channel) so as to realize the Sensing of scenes. For example, wireless fidelity (wireless Fidelity, wi-Fi) Sensing enables motion detection, gesture recognition, and biometric measurement based on existing wireless signals between existing Wi-Fi networks and devices. In Wi-Fi Sensing, changes in the environment caused by the movement of objects, pets and people are detected by using a channel state information (Channel State Information, CSI) based or Radar (Radar) based manner without requiring the detected object to wear any device.

An embodiment of the present application provides a wireless sensing method, where the method is applied to an access point, and fig. 3 is a schematic flow chart of implementation of the wireless sensing method in the embodiment of the present application, as shown in fig. 3, where the method may include the following steps:

s301, an access point receives a first sensing request sent by a first station;

the first station is used as an initiating terminal of a wireless sensing process, a first sensing request is sent to an access point serving as a responder, and the access point receives the first sensing request sent by the first station. Here, the first station may be any one of at least one first station included in the wireless awareness system.

The first awareness request is used for requesting the access point to measure wireless signals so as to initiate a wireless awareness process. In the embodiment of the application, the first Sensing Request is sent in a Sensing Request (Sensing Request) frame manner.

The first request may carry one or more of the following parameters, i.e. combinations of cells: interaction properties, result patterns, location configuration information (Location Configuration Information, LCI) and perceived transmission parameters.

The interaction attribute indicates the role of one or two participating devices in the perception process, the participating devices comprising: the role of the participation equipment comprises a sending end and a receiving end, and the role indicated by the interaction attribute can be one or two roles of the access point and the station. When the interaction attribute indicates the role of one participating device, the role of the other participating device can be directly determined based on the interaction attribute carried in the first perception request. In one example, the subcells of the interaction attribute include: and the sending end is the first station, the interaction attribute indicates that the sending end is the first station, and the receiving end is the access point. In one example, the subcells of the interaction attribute include: the system comprises a sending end and a receiving end, wherein the sending end is a first station, and the receiving end is an access end. In the cell of the interaction attribute, the participating device may be characterized by a device identification of the participating device. Wherein the device identification of the participant device may be an address of the participant device.

The LCI indicates a location, which may include one or more of the following sub-cells: the identity of the LCI sub-cell, the length of the LCI sub-cell and the content of the LCI sub-cell. When the identity of the LCI sub-cell is the first identity, the content of the LCI sub-cell includes longitude, latitude and altitude. When the identity of the LCI sub-cell is the second identity, the content of the LCI sub-cell comprises a mobility state of the first site, wherein the mobility state comprises: fixed, mobile and unknown.

The result pattern indicates the type of measurement result. Wherein the type of test result includes at least one of: CSI, signal-to-Noise Ratio (SNR). The CSI indicates the amplitude and phase of the carrier wave in the channel, and the signal-to-noise ratio is the ratio of the beamformed signal to noise in the channel.

The perceived transmission parameters indicate transmission parameters of the perceived data packet, wherein the transmission parameters may include a channel, a bandwidth, an interval time, and the like of transmission.

Prior to S301, the access point may transmit its own capability awareness information to the first station and receive the capability awareness information of the first station to perform interaction of the capability awareness information between the first station and the access point. The capability sensing information is used for indicating whether the node to which the capability sensing information belongs supports a wireless sensing process.

S302, the access point responds to the first sensing request and determines at least one second station based on station information of the first station;

after receiving the first sensing request of the first station, the access point determines station information of the first station. The site information may include: a combination of one or more of device identification, location information, received signal strength, etc. Wherein the device identification may comprise an address of the device, the location information may comprise an LCI, and the received signal strength may comprise a wireless received signal strength indicator (Received Signal Strength Indicator, RSSI).

Taking the example that the station information comprises the equipment identifier, the access point analyzes the first sensing request to obtain the equipment identifier of the first station.

Taking the case that the site information includes location information as an example, the access point analyzes the first sensing request to obtain the location information of the first site.

Taking the example that the station information includes the received signal strength, the access point obtains the received signal strength of the first station from the first station.

After determining the station information of the first station, the access point may determine at least one second station based on the cooperative policy. The second station may be any station other than the first station among at least one station included in the wireless awareness system. The second stations are stations that are cooperatively perceived with the first station, and the number of the determined second stations can be one or more. The collaborative policy may include one or more of the following policies: the first strategy is to determine at least one second site based on the set association relationship and the first site; and determining a second station in a plurality of third stations based on the station information of the first station, wherein the third station is a station which is connected to the access point and has sensing capability, and the third station can be any station except the first station in the wireless sensing system. In the embodiment of the present application, the cooperative policy of determining the second station based on the station information of the first station is not limited.

In practical application, after receiving a first sensing request of a first station, an access point judges whether to agree to measure wireless signals of the first station according to a first sensing condition, namely, executes a sensing process, and after determining to agree to measure wireless signals, the access point determines at least one second station based on station information of the first station. Wherein the first perceptual condition may comprise: the access point has enough free resources to perform the sensing process, or the access point performs wireless sensing with the first station without affecting the currently ongoing service, etc. The first sensing condition is not limited in any way in the embodiment of the present application.

Here, the access point also generates a first perceived response according to the judgment result, and sends the generated first perceived response to the first station to inform the first station that the perceivable sensing is performed, so as to measure the wireless signal. And when the access point agrees to measure the wireless signal, generating a result identifier indicating acceptance, and generating a first perception response based on the result identifier indicating acceptance. When the access point does not agree to make the measurement of the wireless signal, a result identifier indicating the rejection is generated, and a first perceived response is generated based on the result identifier indicating the rejection.

The first sensing response can also carry interaction attributes and sensing sending data, wherein the interaction attributes in the first sensing response are the negotiated results of the access point based on the interaction attributes required to be carried by the first sensing request, and the sensing sending data in the first sensing response are the negotiated results of the access point based on the interaction attributes required to be carried by the first sensing request.

In the embodiment of the application, the first Sensing Response is sent in a Sensing Response (Sensing Response) frame manner.

S303, the access point acquires at least one second measurement result.

The at least one second measurement is a measurement of a wireless channel between the access point and each of the at least one second station; the at least one second measurement is used to determine a perception result with a first measurement, the first measurement being a measurement of a wireless channel between the access point and the first station.

After determining at least one second site, the access point performs interaction of the perception data packet with each second site in the at least one second site respectively to obtain at least one second measurement result. The second measurement result is a measurement result of the wireless signal between the access point and the corresponding second station in the interactive perception data packet. The access point also interacts with the first station with a perception data packet for determining a measurement result of the wireless signal between the access point and the first station, i.e. a first measurement result. The first measurement result and the at least one second measurement result are used for determining a perception result of cooperative perception.

When the access point interacts with the first station, the sending end of the perception data packet can be the access point or the first station. When the access point interacts with a second station, the sending end of the perceived data packet can be the access point or the second station.

Taking the access point as a sending end of the sensing data packet as an example, the access point respectively sends the sensing data packet to each of the first station and at least one second station, so that the first station determines a first measurement result based on the received sensing data packet, and the second station determines respective second measurement results based on the received sensing data packet.

Taking the access point as a receiving end of the perception data packet as an example, each second station in the first station and at least one second station respectively sends the perception data packet to the access point, the access point determines a first measurement result of the first station based on the perception data packet sent by the first station, and determines a second measurement result of each second station based on the perception data packet sent by each second station.

In the embodiment of the present application, the sensing data packet may be a packet that does not include data.

In this embodiment, as shown in fig. 4, the station accessed by the access point 400 includes: site 401, site 402, site 403, and site 404. The station 401 sends the first awareness request 41 to the access point 400, and after the access point 400 receives the first awareness request 41, determining the station that performs cooperative awareness with the station 401 includes: station 402 and station 403, then access point 400 performs measurement process 42 with station 401, station 402, and station 403, respectively, to achieve cooperative awareness.

The access point may send the measurements to station a, which determines a perceived result based on the received measurements. The access point may also determine a perceived result based on the received individual measurement results, and send the perceived result to site a.

In an example, an access point performs a measurement procedure with stations a, B, C, and D, respectively, and obtains measurement results of wireless channels between the access point and stations a, B, C, and D, respectively: the access point sends the measurement result A, the measurement result B, the measurement result C and the measurement result D to the station A, and the station A determines a perception result through the measurement result A, the measurement result B, the measurement result C and the measurement result D.

In the embodiment of the application, after receiving the first sensing request, the access point analyzes the first sensing request to obtain the interaction attribute carried by the first sensing request, and judges that the access point is a transmitting end or a receiving end of the sensing data packet based on the interaction attribute carried by the first sensing request.

The access point may obtain the sub-cell carried by the interaction attribute by parsing the first sensing request, where the sub-cell may include one or both of a transmitting end and a receiving end.

Taking the sub-cell carried by the interaction attribute as an example, the sending end may be included, if the device identifier of the sending end carried by the interaction attribute is the device identifier of the access point, the access point determines that the access point is the sending end, and if the device identifier of the sending end carried by the interaction attribute is the device identifier of the first station, the access point determines that the access point is the receiving end.
