Method for device-to-device direct communication in wireless communication system, and apparatus therefor

A method for device-to-device direct communication in a wireless communication system according to an embodiment of the present invention is performed by a first terminal, and the method comprises the steps of: setting, as a transmission gap period, a candidate time period in which a first message including location information of a second terminal will be periodically received from the second terminal; and periodically receiving the first message from the second terminal within the transmission gap period. A message is not transmitted from the first terminal through a candidate carrier on which the first message is to be received within the transmission gap period.
