Claim:
1. A method for performing interference cancellation, performed by a terminal, the method comprising: receiving: detecting control information of the interference signal using: performing cancellation of the interference signal using the detected control information, wherein the control information includes a field related to precoding of the interference signal determined differently according to the interference transmission layer restriction information, the information about the number of antenna ports or a field related to Multiple User Multiple Input Multiple Output (MU-MIMO) being included in the control information, wherein the field related to MU-MIMO: wherein, when the interference signal is based on 4-port Cell-specific Reference Signal (CRS): wherein, when the interference signal is based on 2-port CRS, only 1 bit, among the 6 bits, indicates a PMI of the first interference signal and the second interference signal.
