[0045] In order to make those skilled in the art better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Although the disclosure in the present invention is introduced according to one or several exemplary examples, it should be understood that each aspect of these disclosures can also constitute a complete technical solution separately. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0046] In the embodiments of the present invention, "at least one" means one or more, and "more" means two or more. In order to facilitate the clear description of the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order. They are only used for illustration and distinction of the description objects. There is no order, nor does it represent a special limitation on the number of devices in the embodiments of the present invention, and cannot constitute any limitation on the embodiments of the present invention.

[0047] Figure 1 FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present invention. Figure 1 As shown, the communication system includes an access point AP, terminals STA1 and STA2. It should be understood that Figure 1 This is only a schematic diagram of the architecture of the communication system. In the embodiments of the present invention, the number and type of devices in the communication system are not limited. For example, the communication system may include more terminals or access points. In addition, those skilled in the art will understand that according to the principles and functions described herein, the term "access point (AP)" according to the present application can also be used to describe an access port or any other device that can receive and transmit wireless signals within a network architecture. Therefore, the use of the access point is only exemplary.

[0048] In the following embodiments, it is assumed that AP is a wireless routing device in the smart home system, which is a weak computing capability device responsible for connecting various terminal devices in the smart home system. STA1 is a weak computing capability device in the smart home system, such as air conditioners, ceiling lamps, etc. STA2 is a strong computing capability device in the smart home system, such as smart TVs, smart projectors, computers, etc.

[0049] Figure 1In the communication system shown, the access point AP is connected to the terminals STA1 and STA2. The method for establishing a connection between the terminals STA1 and STA2 and the access point AP can refer to the relevant prior art. For example, the process of establishing a connection between the terminals STA1 and STA2 and the access point AP includes the following contents:

[0050] 101. STA1 sends a connection request message (such as an Association request message) to AP, requesting to establish a connection with the AP. The message includes a parameter Sensing process supported, which is used to indicate whether it has sensing computing capabilities. In this embodiment, it is set to 0, indicating that it does not have sensing computing capabilities.

[0051] 102. AP sends a connection response message (such as an Association response message) to STA1, agreeing to establish a connection with STA1. The message may also include a parameter SBP supported, which is used to indicate whether the proxy awareness mode is supported. In this embodiment, it is set to 1, indicating that the proxy awareness mode is supported.

[0052] 103. STA2 sends a connection request message (such as an Association request message) to AP, requesting to establish a connection with the AP. The message includes a parameter Sensing process supported, which is used to indicate whether it has sensing computing capabilities. In this embodiment, it is set to 1, indicating that it has sensing computing capabilities.

[0053] 104. AP sends a connection response message (such as an Association response message) to STA2, agreeing to establish a connection with STA2. The message may also include a parameter SBP supported, which is used to indicate whether the proxy awareness mode is supported. In this embodiment, it is set to 1, indicating that the proxy awareness mode is supported.

[0054] It should be noted that STA1 and STA2 may also send information about whether they have sensing computing capabilities to AP through other messages, such as proprietary information indicating whether they have sensing computing capabilities. Similarly, AP may also send information about whether it supports proxy sensing mode to STA1 and STA2 through other messages, such as broadcast messages.

[0055] When STA1 needs to provide sensing services, if the AP supports the proxy sensing mode, it sends a proxy sensing request message (such as a sensing by proxy request message) to the AP to request the AP to perform the sensing measurement process on behalf of the AP. The proxy sensing request message contains the parameter Sensing report control, which is used to set the information to be reported. For example, Sensingreport control contains the following parameters:

[0056] Result type: the result type of the report. In this embodiment, it is set to event, indicating that the sensing result needs to be reported;

[0057] Event element: event information element. This information element is included when the Result type value is event. For example, this information element contains the following parameters:

[0058] Item number: the number of events that need to be reported, set to a natural number N greater than 0;

[0059] Item 1: Set event 1, such as present, to detect whether there is someone present;

[0060] Item 2: Set event 2, such as number of people, indicating how many people are detected;

[0061] …

[0062] Item N: Set event N, for example, heartbeat, which means detecting heart rate.

[0063] After the AP receives the proxy perception request message sent by STA1, if the Result type indicates that the measured wireless channel information needs to be reported, the AP performs perception measurement with one or more connected terminals and sends the obtained measurement results to STA1. If the Result type indicates that the perception result needs to be reported, the AP performs operations based on its own capabilities and the capabilities of the terminals connected to the AP. If the AP has the perception computing capability, the AP calculates the perception result according to the parameter Sensing report control in the proxy perception request message and sends the calculated perception result to STA1; if the AP does not have the perception computing capability, the AP sends the parameter Sensing report control in the proxy perception request message to STA2 with the perception computing capability, instructing STA2 to calculate the perception result according to the Sensing report control. After STA2 calculates the perception result, it sends it to the AP, and the AP sends the perception result to STA1. Figure 2shown.

[0064] In some embodiments, the AP performs operations according to its own capabilities and the capabilities of the terminal connected to the AP, which may specifically include the following:

[0065] a) If the AP has sensing computing capability, the parameter status code value is set to SUCCESS, indicating that the proxy sensing request is approved, and the parameter status code value is included in a proxy sensing response message (such as a sensing by proxy response message) and sent to STA1;

[0066] b) If the AP does not have the sensing computing capability and the terminals connected to the AP do not have the sensing computing capability, the parameter status code value is set to reject, indicating that the proxy sensing request is rejected, and it is included in the proxy sensing response message (such as the sensing by proxy response message) and sent to STA1.

[0067] c) If the AP does not have the sensing computing capability, and there is a terminal connected to the AP that has the sensing computing capability, the parameter status code value is set to SUCCESS to indicate that the proxy sensing request is approved, and it is included in the proxy sensing response message (such as the sensing by proxy response message) and sent to STA1. Or, d) If the AP does not have the sensing computing capability, and there is a terminal connected to the AP that has the sensing computing capability, after successfully establishing a sensing measurement process with a terminal that has the sensing computing capability, the parameter status code value is set to SUCCESS, and it is included in the proxy sensing response message (such as the sensing by proxy response message) and sent to STA1; if the sensing measurement process is not successfully established with the terminal that has the sensing computing capability, the parameter status code value is set to reject, and it is included in the proxy sensing response message (such as the sensing by proxy response message) and sent to STA1.

[0068] After the AP sends a proxy sensing response message indicating approval of the proxy sensing request to STA1, the AP establishes a sensing measurement process with one or more terminals connected thereto. After the sensing measurement process is successfully established, the AP performs sensing measurement, obtains sensing results, and sends the obtained sensing results to STA1. If the AP executes the content in d) above, the AP first executes the step of establishing the sensing measurement process, and then sends the proxy sensing response message to STA1 according to the establishment result. For example, the AP and the connected terminal establish a sensing measurement process, which may specifically include:

[0069] OP1) If the AP has the sensing computing capability, it may select a terminal with the sensing computing capability and / or a terminal without the sensing computing capability as a responder and establish a sensing measurement process with the responder.

[0070] OP2) If the AP does not have the sensing computing capability, first select a terminal with the sensing computing capability as a responder, and establish a sensing measurement process with it. In this embodiment, STA2 is selected as the responder, and a sensing measurement process is established with it. Optionally, if the sensing measurement process is successfully established with STA2, other terminals with sensing computing capabilities or / and terminals without sensing computing capabilities can be further selected as responders, and a sensing measurement process can be established with them.

[0071] In OP2), in the process of establishing the sensing measurement, the AP sends a sensing measurement setup request message (such as a sensing measurement setup request message) to STA2, and the message may include the following parameters:

[0072] Measurement setup ID: Perception measurement process ID;

[0073] Sensing transmitter: Indicates whether the responder acts as a signal transmitter in the sensing measurement process. If set to 1, it means that the responder acts as a transmitter, otherwise it is set to 0;

[0074] Sensing receiver: indicates whether the responder acts as a signal receiver in the sensing measurement process. If it is set to 1, it means that the responder acts as a receiver, otherwise it is set to 0;

[0075] Sensing report control: Set the information to be reported, which is the same as that in the proxy sensing request message sent by STA1;

[0076] Sensing measurement parameters: Sensing measurement operating parameters, such as transmit power and / or expected received signal strength and / or specified bandwidth such as maximum bandwidth or minimum bandwidth.

[0077] In OP1), the sensing measurement setup request message (such as a sensing measurement setup request message) sent by the AP to any responder, or in OP2), the sensing measurement setup request message (such as a sensing measurement setup request message) sent by the AP to a terminal without sensing computing capability may include the following parameters:

[0078] Measurement setup ID: Perception measurement process ID;

[0079] Sensing transmitter: Indicates whether the responder acts as a signal transmitter in the sensing measurement process. If set to 1, it means that the responder acts as a transmitter, otherwise it is set to 0;

[0080] Sensing receiver: indicates whether the responder acts as a signal receiver in the sensing measurement process. If it is set to 1, it means that the responder acts as a receiver, otherwise it is set to 0;

[0081] Sensing measurement parameters: Sensing measurement operating parameters, such as transmit power and / or expected received signal strength and / or specified bandwidth such as maximum bandwidth or minimum bandwidth.

[0082] If the Sensing receiver is set to 1, the sensing measurement setup request message should also include a Sensingreport control parameter, but the Result type in the parameter is set to CSI, indicating that the measured wireless channel information needs to be reported.

[0083] After the AP receives the perception measurement establishment response message (such as the sensing measurementssetup response message) sent by the responder, if the perception measurement establishment response messages sent by all responders indicate that the establishment of the perception measurement process is refused, the establishment of the perception measurement process fails. If the AP sends the proxy perception response message using a method other than d), it may also send a proxy perception termination message (such as a sensing by proxy termination message) to STA1 to instruct the termination of proxy perception; if there is a perception measurement establishment response message sent by a responder that indicates agreement to establish the perception measurement process, the perception measurement process is successfully established.

[0084] After the sensing measurement process is successfully established, the AP performs sensing measurement with the responder that successfully establishes the sensing measurement process, obtains the sensing result, and sends the obtained sensing result to STA1. For OP1), the AP performs sensing measurement with any responder that successfully establishes the sensing measurement process, obtains the measurement result, and calculates the sensing result based on the measurement result and the parameter Sensing report control in the proxy sensing request message, and then sends the sensing result to STA1. For OP2), it specifically includes:

[0085] 201. After receiving the sensing measurement setup response message (such as sensing measurements setup response message) sent by STA2, if the message indicates that the sensing measurement process is refused to be established, the sensing measurement process with STA2 fails to be established. If it corresponds to the above c), the AP sends a proxy sensing termination message (such as a sensing by proxy termination message) to STA1 to indicate the termination of proxy sensing; if the message indicates that the sensing measurement process is agreed to be established, the sensing measurement is performed with STA2. For example, the sensing measurement performed by AP and STA2 may specifically include the following contents:

[0086] 2011. If the Sensing receiver is set to 1 in the sensing measurement establishment request message, the AP sends a sensing signal to STA2, and STA2 measures the wireless channel information between the AP and STA2 to obtain a measurement result.

[0087] 2012. If the Sensing transmitter is set to 1 in the sensing measurement setup request message, the AP sends a trigger message to instruct STA2 to send a sensing signal, measures the wireless channel information between the AP and STA2 according to the sensing signal sent by STA2, and sends the measurement result to STA2.

[0088] 202. STA2 calculates and obtains the sensing result according to the measurement result obtained by itself or the measurement result sent by the AP and the parameter Sensing report control sent by the AP.

[0089] 203. After obtaining the sensing result, STA2 sends the sensing result to AP.

[0090] 204. The AP sends a proxy sensing report message (such as a sensing by proxy report message) to STA1, where the message includes the obtained sensing result.

[0091] It should be noted that, in the process of establishing the perception measurement between AP and STA2, the parameter Sensing report control in the proxy perception request message may not be included in the perception measurement establishment request message, and AP may send the parameter Sensing report control in the proxy perception request message to STA2 through other messages. In addition, if AP has established a perception measurement process with STA2 before STA1 requests AP to perform the perception measurement process on behalf of STA1, and if the established perception measurement process can meet the requirements of the perception service that STA1 needs to provide, the established perception measurement process can be directly used, and AP may include the parameter Sensing report control in the proxy perception request message sent by STA1 in other messages and send it to STA2.

[0092] After AP and STA2 successfully establish a sensing process, AP can also establish a sensing measurement process with STA3. After STA3 agrees to establish the sensing measurement process, AP and STA3 perform sensing measurement, obtain measurement results, and send the obtained measurement results to STA2. STA2 calculates the sensing result based on the measurement results sent by AP and Sensing report control. At this time, the sensing result sent by STA2 to AP is the sensing result after STA2 integrates multiple sensing results (such as the sensing result calculated by STA2 based on the measurement results obtained by AP and STA2 performing sensing measurement and the sensing result calculated by STA2 based on the measurement results obtained by AP and STA3 performing sensing measurement).

[0093] In some embodiments, the AP may perform sensing measurements only with terminals other than STA2, and then send the obtained measurement results to STA2 for STA2 to calculate the sensing results. If the AP is also connected to the terminal STA3, the AP may perform sensing measurements with STA3, and send the obtained measurement results (including the wireless channel information between the AP and STA3 measured by the AP or STA3) to STA2, and STA2 calculates the sensing results based on the measurement results sent by the AP and the Sensing report control. At this time, the sensing results sent by STA2 to the AP are the sensing results calculated by STA2 based on the measurement results obtained by the sensing measurements performed by the AP and STA3.

[0094] The embodiment of the present invention further provides a wireless sensing device, including a wireless sensing module, wherein the wireless sensing module is used to perform the following steps:
