There is provided a transmitting/receiving method performed by a user equipment (UE) including a dedicated radio frequency (RF) chain for a proximity service (ProSe). The method may comprise: receiving configuration information for a discovery resource pool, the discovery resource pool including a bitmap representing a subframe used for a discovery signal and information representing the number of times when the bitmap is repeated; turning on the dedicated RF chain based on a subframe corresponding to a first bit 1 in a bit string enumerated by the bitmap and the number of repetition times; turning on the dedicated RF chain and thereafter, transmitting/receiving a signal to/from an adjacent UE; and turning off the dedicated RF chain based on a subframe corresponding to a last bit 1 in the bit string.
