Abstract
Embodiments of the present invention provides a method and an apparatus for channel access for the transmission of a signal. The method includes: counting down, by a first device, an initial value N of a random backoff counter within a contention window; sensing, by the first device, a channel status; determining, by the first device, whether or not to perform transmission of the signal within a periodic window based on the sensed channel status; transmitting, by the first device, the signal after sensing the channel to be idle. Therefore, the channel access method and apparatus adapt to the data and control traffic load in the channel using LBT with random back-off with a contention window of variable size.
