    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: This application discloses a scheduling method, an access point, and a station. The method includes: generating, by an access point AP, a first frame, where the first frame includes reservation information of each of at least one trigger frame, a first trigger frame is any one of the at least one trigger frame, and reservation information of the first trigger frame includes an identifier of the first trigger frame, start time of the first trigger frame, and a constraint condition of a station STA corresponding to the first trigger frame; and broadcasting, by the AP, the first frame to at least one STA. Therefore, by using the method provided in the present invention, dynamic network changes can be supported through unified scheduling of the AP, and this is favorable to coordination between the AP and the STA, thereby better reducing power consumption of the STA.
