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.

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: Disclosed herein are a method of performing synchronization in a distributed wireless communication system, and a terminal supporting the same. A distributed wireless communication system includes a plurality of networks. Time resources of each of a plurality of networks are divided into a synchronization slot, a discovery slot, a peering slot, and a data slot. A first terminal belonging to a first network determines whether a synchronization signal is received from a terminal belonging to a second network in the data slot of the first network. The first terminal detects whether it has met the second network that is out of synchronization with the first network if the synchronization signal is determined to have been received.

Abstract: A method of synchronization in a distributed wireless communication system and a terminal supporting the same are disclosed. A terminal increases its contention window value if it receives a synchronization signal within a synchronization slot. The terminal decreases its contention window value if it receives no synchronization signal within the synchronization slot. The terminal determines whether to transmit a synchronization signal or not by using the increased or decreased contention window value.
