Abstract: Embodiments of the present disclosure relate to the communications field, and in particular, to a method, an access point, and a station for data transmission in a wireless local area network, so as to reduce energy consumption in a data transmission process. In the embodiments of the present disclosure, the STA may not listen to a trigger frame after receiving the first indication information, and wakes up at the first target wakeup moment. In addition, after waking up, the STA does not miss time for listening to the target trigger frame. This reduces energy consumption in a data transmission process.

Abstract: Embodiments of the present disclosure disclose a method and an apparatus for transmitting a trigger frame in a wireless local area network. The method for transmitting a trigger frame in a wireless local area network includes: generating, by an access point, a trigger frame carrying a target media access control MAC function, where the trigger frame includes indication information, the indication information is used to instruct a first station to send a MAC frame corresponding to the target MAC function, and the indication information is used to instruct a second station not to perform the target MAC function; and sending, by the access point, the trigger frame. In the present disclosure, the indication information is used to instruct the first station to send the MAC frame corresponding to the target MAC function without limiting the second station, so that data sending manners of the first station and the second station can be flexibly controlled.

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.
