Abstract: The present invention relates 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 invention, 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.
