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: This application provides a wake-up method, a station, and an access point. The method is performed in a communications system. The communications system can include an access point (AP) and at least one station (STA). The AP includes a wake-up transceiver (WUR) and a main transceiver. The method can include determining, by a first STA, that the AP is in a sleep state, where when the AP is in the sleep state, the main transceiver of the AP is in an off state. The method can also include transmitting, by the first STA, a wake-up frame to the WUR of the AP, where the wake-up frame triggers the WUR of the AP to wake up the main transceiver of the AP. Therefore, an uplink data transmission latency can be reduced.

Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.
