Provided herein is a method for interference cancellation for a UE having interference cancellation capability in a wireless communication system, the method comprising: receiving information on a reference signal transmitted from an interfering cell having the possibility of causing inter-cell interference; and attempting to detect the reference signal using the received information on the reference signal, wherein the information on the reference signal is received when the interfering cell and a serving cell of the UE have the same cyclic prefix (CP) length and are synchronized with each other.
