[0003] With the rapid development of mobile communication technologies, Wireless Fidelity (Wi-Fi) technology has made great progress in terms of transmission rate and throughput. Currently, the research content of Wi-Fi technology, such as bandwidth transmission of 320Mhz, aggregation and coordination of multiple frequency bands, etc., and its main application scenarios, such as video transmission, Augmented Reality (AR), Virtual Reality (VR), etc.

[0004] Specifically, the aggregation and coordination of multiple frequency bands refer to devices communicating with each other simultaneously in the 2.4GHz, 5.8GHz, 6GHz, and other frequency bands. For the scenario where devices communicate with each other simultaneously in multiple frequency bands, a new Media Access Control (MAC) mechanism needs to be defined for management. In addition, the aggregation and coordination of multiple frequency bands are expected to support low-latency transmission.

[0005] Currently, in the technology of aggregation and coordination of multiple frequency bands, the maximum supported bandwidth is 320MHz (160MHz + 160MHz). In addition, 240MHz (160MHz + 80MHz) and other bandwidths supported by existing standards may also be supported.

[0006] In the currently studied Wi-Fi technology, Wireless Local Area Network (WLAN) Sensing technology may be supported. For example, application scenarios such as location discovery, proximity detection, and presence detection in dense environments (such as home environments and enterprise environments). During the WLAN sensing measurement process, the sensing response end will send a sensing measurement report to the sensing initiating end. Therefore, a format of a wireless frame for sending the sensing measurement report needs to be provided to meet the WLAN sensing measurement requirements. Summary of the Invention

[0051] The embodiments of the present disclosure provide a communication method, a device, an electronic device, and a storage medium, which are used to provide a format of a wireless frame for sending a sensing measurement report.

[0052] Among them, the method and the device are based on the same inventive concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0053] As Figure 1 shown, the embodiments of the present disclosure provide a communication method. Optionally, the method can be applied to a sensing response end, and the method may include the following steps:

[0054] Step 101: Send a target wireless frame. The target wireless frame includes a Sensing Measurement Report information element. The Sensing Measurement Report information element includes a Sensing Measurement Report Control field, and the Sensing Measurement Report Control field includes a grouping subfield that indicates the number of subcarrier groups for the sensing initiator to perform channel sensing.

[0056] As a first example, refer to Figures 2 to 4 , and first introduce the architecture of WLAN Sensing and the WLAN Sensing process applied by the communication method provided in the embodiments of the present disclosure.

Among them, the Sensing Initiator (or Initiator) initiates WLAN Sensing (for example, initiates a WLAN sensing session), and there may be multiple Sensing Responders (or sensing receivers) or responders to respond to it, as shown by Responder 1, Responder 2, and Responder 3 in Figure 2 . When the Sensing Initiator initiates WLAN Sensing, multiple associated or non-associated Sensing Responders of WLAN Sensing can respond.

[0058] Refer to Figure 3 , the Sensing Initiator and the Sensing Responder communicate through a communication connection, as shown by communication connection S1; the Sensing Responders communicate with each other through communication connection S2.

[0059] Among them, each sensing initiator can be a client; each sensing responder (in this example, namely Sensing Responder 1 to Sensing Responder 3) can be a station device (STA) or an access point device (AP). In addition, the STA and AP can assume multiple roles during the WLAN sensing process; for example, during the WLAN sensing process, the STA can also be a sensing initiator, and the sensing initiator may be a sensing transmitter, a sensing receiver, or both, or neither. During the WLAN sensing process, the sensing responder may also be a sensing transmitter, a sensing receiver, or both.

[0060] As another architecture, as Figure 4 shown, both the sensing initiator and the sensing responder can be clients, and the two can communicate by connecting to the same access point device (AP); Figure 4 where Client1 is the sensing initiator and Client2 is the sensing responder.
