Abstract

A method performed by a device for performing synchronization between devices for a Device-to-Device (D2D) communication is provided. The method includes setting, according to a process of the device, the device to a group of devices for performing a dynamic switching; outputting a synchronization signal corresponding to the set group as a signal for setting synchronization in a physical layer; controlling, upon receiving another synchronization signal from another device, the outputting of the synchronization signal by applying a time offset according to a relation between the set group that includes the device and the group that includes the another device; and setting, if the synchronization signal and the another synchronization signal are converged, synchronization of the device based on a time point where the synchronization signal is output.
