METHOD AND APPARATUS FOR RECEIVING DOWNLINK SIGNALS IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of receiving a downlink signal at a user equipment (UE) in a wireless communication system, the method comprising:
- receiving information related to an interference signal from a serving cell; and
performing interference cancellation in physical resource block (PRB) pairs used to transmit the downlink signal based on the information related to the interference signal,wherein the information related to the interference signal includes use of each of the PRB pairs in a neighbor cell of the serving cell and an enhanced physical downlink channel (EPDCCH) transmission type if each PRB pair is used for an EPDCCH.

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.
