Abstract: Disclosed is a synchronization method in a distributed wireless communication system and a terminal supporting the same. In a synchronization method, a terminal splits a synchronization period into a plurality of backoff slots and randomly selects a backoff counter using the contention window. Furthermore, the terminal checks whether a channel is idle during at least one of the plurality of backoff slots and changes the backoff counter based on a result of the check.

Abstract: Provided are a random access method and a terminal supporting the random access method. The terminal may monitor a state of a channel, when the state of the channel is idle, attempt a packet transmission at a first packet transmission probability, and transmit a packet including the first packet transmission probability.
