Abstract

Provided is an interference removal method in a multi-node system. The method comprises the steps of: receiving node information from a base station; receiving a first signal from a destination node and receiving a second signal from an interference node; and removing interference caused by the second signal by applying a reception filter to received signals which include the first signal and second signal, wherein the node information includes information on at least one reference signal of the interference node and information on a precoding matrix applied to the second signal, and the reception filter is determined on the basis of the node information.
