Method and apparatus for cancelling an interference signal in wireless communication system

The present invention relates to a method and an apparatus for cancelling an interference signal in a wireless communication system. A method for cancelling an interference signal for a terminal, which performs device-to-device (D2D) communications, in a wireless communication system comprises the steps of: receiving interference signal information for cancelling a cellular interference signal for the terminal from a base station; cancelling the cellular interference signal from a signal received by the terminal based on the interference signal information; and processing a D2D communication signal for the terminal.
