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.

Abstract: Embodiments of the present invention disclose a timing value adjustment method and apparatus, which relate to the communications field and reduce a probability that power of a terminal exceeds a limit. A specific solution is that: an absolute timing difference of a timing advance group TAG pair is obtained according to an absolute value of a difference between transmit timing values or receive timing values of the two TAGs in the TAG pair, where the TAG pair is formed by any two TAGs in a TAG set; and it is determined that the absolute timing difference of the TAG pair meets a predetermined condition, and first signaling is sent to a network device, where the first signaling includes identifiers of the two TAGs in the TAG pair. The present invention is used in a timing value adjustment process.
