Abstract

The present invention relates to a communication technology and system converging the 5G communication system for supporting a data rate higher than that of the 4G system with IoT technology. The present invention is applicable to intelligent services based on 5G communication and IoT technologies (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety services. In detail, the discovery signal transmission method of a terminal in a wireless communication system supporting Device to Device (D2D) communication includes receiving discovery resource pool information from a base station, selecting a resource for transmitting discovery signal based on the discovery resource pool information, determining whether the selected resource is overlapped with a resource configured for transmitting a D2D synchronization signal, and determining whether to transmit the discovery signal based on the determination result.
