Method for removing interference in wireless communication system and device for same

A method for enabling a user equipment (UE) to receive information required for cancellation of an interfering signal from a received signal in a wireless communication system, the method comprising the steps of:

• reporting, to a base station, carrier aggregation (CA) related capability of the UE;
• and
• receiving, from the base station, information on a cancellation scheme of an interfering signal of the UE, which is determined on the basis of the CA related capability,
• wherein the information on the CA related capability includes a CA bandwidth class and MIMO capability of the UE for each band of each band combination for the CA.

A base station for supporting cancellation of an interfering signal from a received signal of a user equipment (UE) in a wireless communication system, the base station comprising:

• a radio frequency (RF) unit;
• and
• a processor configured to control the RF unit,
• wherein the processor is configured to receive, from the UE, information on capability relating to carrier aggregation (CA), determine a cancellation scheme of an interfering signal of the UE, on the basis of the information on capability relating to CA, and transmit, to the UE, the determined cancellation scheme of the interfering signal, and the information on capability relating to CA includes a CA bandwidth class and MIMO capability of the UE for each band of each band combination for the CA.
