Abstract
The present disclosure relates to a pre-fifth generation (5G) or 5G communication system to be provided for supporting higher data rates beyond fourth generation (4G) communication system such as long term evolution (LTE).A synchronization signal transmission/reception method for use in a device-to-device (D2D) communication system is provided. A method of transmitting a synchronization signal for D2D communication in an asynchronous network, in which a first terminal located in a first cell controls synchronization with a second terminal located outside of the first cell, includes transmitting, at the first cell, a system information block (SIB) including resource allocation information of the first cell and at least one neighboring cell, determining whether the first terminal is in a first mode and whether the first terminal is scheduled to perform one of a D2D communication and a D2D discovery; determining, when the first terminal is in the first mode, whether the first terminal is required to transmit a D2D synchronization signal (D2DSS); and transmitting, when the first terminal is required to transmit the D2DSS, scheduling information including a transmission time point and t…
