Method and terminal for direct communication between terminals

摘要

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.

1. A method of communicating, the method comprising, by a receiving terminal:
receiving a plurality of synchronization information parts; selecting synchronization information to acquire a reference time from among the plurality of synchronization information parts according to a priority order; and acquiring the reference time through the selected synchronization information, wherein the priority order assigns a first priority to first synchronization information that is received from a base station, a second priority to second synchronization information that is received from a global positioning system (GPS), and a third priority to third synchronization information that is received from a transmitting terminal, wherein the third priority is based at least partly on a hop count to the transmitting terminal from the base station or the GPS.
