FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a method and device that allow a terminal to transmit a signal for communication between devices (D2D communications) in a wireless communication system. In particular, the present invention transmits a synchronization signal for the D2D communication and a demodulation reference signal (DM-RS) for demodulating the synchronization signal. The base sequence of the demodulation reference signal is generated using the synchronization reference signal identifier (ID).
EFFECT: improving the signal transmission quality.
