1. A method of receiving a downlink signal at a user equipment (UE) in a wireless communication system, the method comprising:
- receiving interference information on a PRB (Physical Resource Block) pair used to transmit the downlink signal from a serving cell;
determining a first resource region in the PRB pair in which the UE performs interference cancellation; and
performing interference cancellation in the first resource region based on the interference information, the interference information being of a second resource region,wherein the second resource region corresponds to the first resource region,wherein the interference information includes use of each of information of PRB pairs, transmission type information, and information on whether an interference of the second region is homogeneous to an interference of the first resource region, andwherein the UE performs interference cancellation only in the first resource region corresponding to a physical downlink shared channel (PDSCH) or enhanced physical downlink control channel (EPDCCH) allocated region of the second resource region.

Abstract
One embodiment of the present invention relates to a method by which a terminal receives downlink signals in a wireless communication system. The method for receiving downlink signals include the steps of: receiving information related to an interference signal from a serving cell; and removing interference from a pair of physical resource blocks (PRBs) used for transmitting the downlink signal, wherein the information related to the interference signal includes each use of the PRB pair in a neighboring cell of the serving cell and, when the use is an EPDCCH, an EPDCCH transmission type.

12. A user equipment (UE) apparatus is in a wireless communication system, the UP apparatus comprising:
-
a receiver; and a processor, wherein the processor configured to; control the receiver to receive interference information on a PRB (Physical Resource Block) pair used to transmit the downlink signal from a serving cell, determine a first resource region in the PRB pair in which the UE apparatus performs interference cancellation, and perform interference cancellation in the first resource region based on the interference information, the interference information being of a second resource region, wherein the second resource region corresponds to the first resource region, wherein the interference information includes use of each of information of PRB pairs, transmission type information, and information on whether an interference of the second resource region is homogeneous to an interference of the first resource region, and wherein the processor performs interference cancellation only in the first resource region corresponding to a physical downlink control channel (PDCCH) or enhanced physical downlink control channel (EPDCCH) allocated region of the second resource region.
