Abstract: A cooperative communication method receives an announcement frame from a master access point. The announcement frame includes a duration field, a value of the duration field is set to a first duration, an end time of the first duration is not later than an end time of a target trigger frame or is not later than a start time of a target trigger based (TB) physical layer protocol data unit (PPDU), the target trigger frame is a next radio frame of the announcement frame, the target TB PPDU is a response frame for the target trigger frame, the target trigger frame comprises a second trigger frame, and the target TB PPDU comprises a second TB PPDU. The slave access point sends the second trigger frame to a second station associated with the slave access point, and receives the second TB PPDU from the second station.

Abstract: A midamble indication method includes sending, by a first device, midamble indication information to a second device. A duration of a midamble indicated by the midamble indication information is greater than or equal to a threshold. The threshold is related to a processing capability of the second device. In a midamble receiving method, the second device receives the midamble according to the indication information.
