Method for receiving synchronizing signals for direct communication between terminals in wireless communication system, and device for same

The present invention provides a method for receiving synchronizing signals for direct communication between terminals and a device for same, which are used in a wireless communication system. The method whereby terminals transmit/receive synchronizing signals, according to one aspect of the present invention, may comprise the steps of: obtaining synchronization by receiving a synchronizing signal from a first-type device; receiving information on a synchronization mode, which indicates a first or second synchronization mode, from the first-type device; and if the synchronization mode is the second synchronization mode, receiving a synchronizing signal from a second-type device so as to obtain synchronization for direct communication between the terminals.
