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

A user equipment (UE) for receiving a signal from a serving cell using network-assisted interference cancellation and suppression (NAICS) in a wireless communication system, the UE comprising;

• a radio frequency (RF) unit that transmits and receives signals;
• and
• a processor that:
• transmits UE capability information to the serving cell including information related to interference transmission modes (TMs) supported by the UE in carrier aggregation;
• receives network assistance information corresponding to the UE capability information from the serving cell;
• and
• receives the signal from the serving cell on a predetermined frequency resource region, the signal received using the received network assistance information based on an assumption that an interference TM of the interference cell is same as a TM of the serving cell,
• wherein the transmitted UE capability information further includes port number information related to a number of common reference signal (CRS) ports in an interference cell for which the UE is capable of performing NAICS.
