    摘要: Embodiments of the present invention provide a method for sending an uplink multi-user transmission trigger frame, an access point, and a station. The access point sends, to a station, a beacon frame that carries a trigger frame information element, where the trigger frame information element includes sending information of a trigger frame. The station obtains a target transmission time sequence of the trigger frame according to the sending information. The access point contends for a channel when a target transmission time of the trigger frame arrives, and the access point sends the trigger frame to the station after the contention succeeds. 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.
