Abstract
A direct communication method between terminals is provided. When a terminal receives a plurality of synchronization information parts, the terminal selects synchronization information to acquire a reference time among the plurality of synchronization information parts according to a priority. Here, the priority is an order of first synchronization information that is received from a base station, second synchronization information that is received from a global positioning system (GPS), and third synchronization information that is received from a terminal in which a hop count from the base station or the GPS is small.
