Disclosed in the present invention is a method for performing device-to-device communication between units of user equipment outside of a coverage area of a base station in a wireless communication system. More specifically, the method comprises the steps of: dividing into a plurality of candidate sections a specific time unit for the device-to-device communication; detecting a reference signal, which is transmitted from a second user equipment from among the units user equipment, from one section of the candidate sections that is not the last section; obtaining synchronization for device-to-device communication with the second user equipment based on the reference signal; and transmitting a predetermined authorization signal from the last section of the candidate sections or from a time unit after a specific time unit. |
