摘要： 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.

摘要： A first terminal generates a first scheduling request signal including information about first data resources for data transmission when the first terminal tries to reserve the first data resources. The first terminal generates a first scheduling request indication signal providing notification that the first scheduling request signal is to be transmitted. The first terminal transmits the first scheduling request indication signal through a first request subslot included in a first scheduling request resource before transmitting the first scheduling request signal. The first terminal transmits the first scheduling request signal through a second request subslot included in the first scheduling request resource.

摘要： A method for a communication link establishing device to establish a communication link in a targeted communication system is provided. A source terminal transmits a source terminal's identification information and threshold value information for selecting a relative angle measurement target to neighboring terminals including a target terminal, and transmits a relative angle measurement request signal to the target terminal and the neighboring terminals. Upon receipt of a response signal for the relative angle measurement request signal from at least one of the neighboring terminals including the target terminal, a communication link with the selected communication target's terminal is established based on the information contained in the response signal.
