Method for interference cancellation in wireless communication system and apparatus therefor

A base station (BS) for supporting a terminal having interference cancellation capability in a wireless communication system, comprising:

• a receiver and a transmitter;
• and
• a processor controls the receiver and the transmitter,
• wherein the processor configures, information on a neighbor cell for interference cancellation;
• and
• controls the transmitter to transmit the information on the neighbor cell to the terminal,
• wherein the information on the neighbor cell is used for the terminal to perform cancellation of interference signal transmitted from the neighbor cell, and
• wherein the information on the neighbor cell indicates that a cyclic prefix (CP) length of the neighbor cell is the same as a CP length of a serving cell of the terminal, and that the neighbor cell is subframe-synchronized to the serving cell.

A terminal having interference cancellation capability in a wireless communication system, comprising:

• a receiver and a transmitter;
• and
• a processor controls the receiver and the transmitter,
• wherein the processor controls the receiver to receive information on a neighbor cell for the interference cancellation from a serving cell of the terminal, and performs cancellation of interference signal transmitted from the neighbor cell using the received information on the neighbor cell,
• wherein the information on the neighbor cell indicates that a cyclic prefix (CP) length of the interfering cell is the same as a CP length of the serving cell, and that the neighbor cell is subframe-synchronized to the serving cell.
