Kind Code:
A1
Abstract:
Provided in the present invention are a method and a device for recognizing the BSS home of a received frame. The method comprises: a station (STA) receiving a reference frame from an associated access point (AP), and measuring the received signal strength of the reference frame to obtain a reference RSSI, the STA receiving a target frame, and measuring the received signal strength of the target frame to obtain a first RSSI, the format of the target frame being HE MU PPDU format, HE SU PPDU format of DL or HE ER SU PPDU format of DL, the physical header of the target frame comprising Color; when the target frame satisfies a first condition, and when the absolute value of the difference between the first RSSI and the reference RSSI is smaller than a predefined value, the STA determining that the target frame is the present BSS frame, the first condition comprising: the Color in the physical header of the target frame matching the Color of the STA. In the case of a Color conflict, the present invention also enables the STA to determine the BSS home of some of the HE PPDU, thereby realizing the purpose of saving power, increasing transmission opportunities and improving system throughput.
