Abstract: A transmit power control method of a terminal in direct communication between terminals is disclosed. The terminal measures a path loss gain of a base station, and compares the measured path loss gain with a predetermined threshold value. The terminal sets a power value for direct communication in the case in which the measured path loss gain is less than or equal to the predetermined threshold value, and performs the direct communication at the set power value.

Abstract: 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.
