1. A method performed by a first user equipment (UE) for transmitting a first signal for a direct communication between UEs in a wireless communication system, the method comprising:
transmitting a discovery signal in a discovery resource region;
receiving, from a second UE, a discovery response signal for the discovery signal; and
selecting one resource region from among a plurality of resource regions associated with the discovery resource region; and
transmitting, to the second UE in the one resource region, the first signal,
wherein a nominal power and a scaling factor related to a transmission power of the first signal are determined based on a cyclic prefix (CP) type and a subcarrier spacing (SCS) configured for the one resource region.
