Embodiments of the present invention relate to a method for transmitting/receiving a signal related to a device-to-device (D2D) communication by a first user equipment in a wireless communication system. The method comprises the steps of: stopping uplink transmission in a first band for a predetermined time interval and searching for a signal transmitted by a second user equipment; and transmitting a report to a third user equipment when the signal transmitted by the second user equipment is found, wherein the report contains the existence of the second user equipment and information related to a band in which the signal from the second user equipment is received.
