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.

摘要： An apparatus for spatial filtering receives a signal transmitted from a first terminal and detects a synchronization start point in time from a transmission frame included in the signal. The apparatus for spatial filtering demodulates a user-defined sequence included in the transmission frame and the at least one SRJBF sequence when the synchronization start point in time is detected, and then estimates a relative angle based on the demodulated user-defined sequence and SRJBF sequence.

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： 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.

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.
