Abstract
A channel selection method and a transmit end are provided. 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.
