Abstract: A method and apparatus for transmitting control information to a User Equipment (UE) by an evolved Node B (eNB) for interference measurement in a wireless communication system are provided. The eNB determines whether the UE can perform interference management for receiving a data signal transmitted from the eNB based on information of an interference signal. When it is determined that the UE can perform the interference management, the eNB transmits to the UE configuration information for receiving the data signal by applying the interference management by the UE, and then transmits to the UE downlink control information including transmission power control information indicating whether a transmission power of a DeModulation Reference Signal (DMRS) corresponding to the interference signal is different from a transmission power of the interference signal.

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.
