Method and apparatus for determining contention window size in communication system
A wireless device of a communication system randomly selects a backoff counter at a contention window interval corresponding to a contention window size that is determined according to a backoff stage, attempts packet transmission, when the backoff counter becomes 0 while reducing the backoff counter, when a radio channel is in an idle status, and increases the contention window size while increasing the backoff stage by 1 according to a first predetermined condition. In this case, as the backoff stage increases, a contention window size has a concave down increasing form.
