Abstract: An access point generates a beacon frame that carries a trigger frame information element comprising sending information of a trigger frame for indicating a sending period of the trigger frame; and sends the beacon frame. In this case, the station switches to an active state, and receives the trigger frame by listening to the channel, and the station performs uplink transmission according to indication of the trigger frame after receiving the trigger frame. In this way, when signaling overheads are not increased and reliability is ensured, a station can learn of a sending time of a trigger frame, and the station remains in a receiving state in an appropriate period of time.

Abstract: This application provides a spatial reuse method and apparatus based on multi-access point (AP) coordination, and a system. In the method, a first access point AP sends a radio frame including identification information to a second access point AP. The identification information is used to indicate the second access point AP to perform spatial reuse during uplink data transmission performed by at least one first station associated with the first access point. The second access point sends a downlink frame to at least one second station based on the identification information. Through coordination between access points APs, the first AP may configure a spatial reuse transmission opportunity for another specific AP to perform spatial reuse transmission, so that a transmission time in the spatial reuse transmission opportunity is fully used, thereby avoiding a conflict and improving transmission efficiency.

Abstract: Embodiments of this application describe a communication method, a first station (STA), a second STA, and an access point (AP). The method includes: determining, by a first STA, a first basic service set (BSS) color; generating, by the first STA, a data frame when the first station STA and a second STA perform D2D transmission, where the data frame includes the first BSS color; and sending, by the first STA, the data frame to the second STA. The first BSS color is carried in the D2D data frame, so that when receiving the data frame, another receiving station in a BSS to which the first STA and the second STA belong can determine that the frame is a frame from a neighboring cell.
