1. A method of transmitting a signal by a user equipment (UE) via a communication between the UE and another UE, the method comprising:
generating a plurality of bits for a physical channel including synchronization related information for the communication;
generating a demodulation reference signal (DM-RS) related to the physical channel, based on an orthogonal code, a cyclic shift, and a sequence; and
transmitting the physical channel and the DM-RS to the other UE,
wherein each of the orthogonal code, the cyclic shift, and the sequence is determined based on a synchronization identity for the communication.
