The present invention relates to a method by which a terminal receives a downlink signal from a base station in a wireless communication system. In detail, the method includes the steps of: receiving information about resource elements for interference channel estimation from an adjacent base station; estimating the interference channel from the adjacent base station using the resource elements for the interference channel estimation; and applying reception beam forming to avoid the interference channel and receive the downlink signal from the base station, wherein the downlink signal is not mapped to the resource elements for the interference channel estimation.
