Abstract
A method for allowing terminals to exchange discovery or synchronization signals to determine their presences among each other within a service area of a base station is provided. The method includes collecting multicast identifiers of another terminal for use in multicast communication, receiving a multicast control channel for Device-to-Device (D2D) multicast communication, performing Cyclic Redundancy Check (CRC) on the received multicast control channel using the collected multicast identifiers, and receiving, when the CRC is successful, the D2D multicast according to the multicast control channel. The D2D communication method and apparatus is advantageous in that the D2D terminal is capable of transmitting the discovery or synchronization signal to discover the neighbor terminals without disturbing downlink or uplink communication between the base station and the terminal, wherein the base station configures the resource for D2D communication so as to support D2D communication without an inter-device interference.
