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: An access device constructs a beacon frame, where the beacon frame includes a newly added field, and the newly added field represents multiple data guard interval lengths supported by the access device. The access device broadcasts the beacon frame, so that a terminal selects an available guard interval length matching a data guard interval length supported by the terminal from the beacon frame, and performs data communication with the access device by using the available guard interval length. Data communication between the access device and the terminal can be implemented when the access device supports multiple data guard interval lengths.

Abstract: Embodiments of this application provide a service data transmission method, an access point, and a station. The method includes: receiving, by a station, a control frame, where the control frame includes control information; contending for a resource based on the control information; and sending first-type service data of the station to an access point on the resource obtained by contention, where the control information is used to instruct the station to contend for the resource used to transmit the first-type service data. In the embodiments of this application, the access point triggers the station to perform a procedure of reporting uplink first-type service data, and this can improve transmission efficiency of service data.
