The embodiments of the present disclosure provide a communication method, an electronic device, and a storage medium, for providing an implementation method for an AP to broadcast capability information of whether neighboring APs support WLAN Sensing.

Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

As shown in FIG1 , an embodiment of the present disclosure provides a communication method, which may be optionally applied to a first access point (AP) device; optionally, in an embodiment of the present disclosure, the AP is, for example, a device having a wireless to wired bridging function, and the AP is responsible for extending the services provided by the wired network to the wireless network; the station device (STA) is, for example, an electronic device having a wireless network access function, and provides a frame delivery service to enable information to be transmitted.

As a first example, refer to FIG. 2, which shows a specific application scenario in an embodiment of the present disclosure. As shown in FIG. 2, a first AP has multiple neighboring APs, such as AP2, AP3, ..., APn; a second AP may be one or more of AP2, AP3, ..., APn; wherein, when there are multiple second APs, the capability parameter information of the perception measurement capability supported by each of the second APs may be different, then the first wireless frame may include each of the second APs.

Step 304: The first wireless frame includes second identification information, and the second identification information identifies whether the capability parameter information of the second AP is the same as or different from the capability parameter information of the first AP, and then step 305 or step 306 is performed.
