Abstract: Embodiments provide a channel selection method and a transmit end, and the method includes: ranking multiple channels, and generating a backoff count value; sequentially decrementing, from an initial timeslot, the backoff count value in each timeslot according to a ranking sequence of the channels and busy/idle states of all the channels until the backoff count value is 0; and selecting, from the multiple channels according to a result of the decrement performed on the backoff count value and a busy/idle state of at least one of the multiple channels, a channel that is used by the transmit end for sending data. The method and the transmit end can improve channel utilization.

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.
