    摘要： The present invention provides an interference removal method in a multi-node system. The interference removal method comprises receiving node information from a base station; receiving a first signal from an objective node and a second signal from an interference node; and removing interference due to the second signal by applying a receive filter to a receive signal including the first and the second signal, where the node information includes at least one of information about a reference signal included in the second signal and information about a pre-coding matrix applied to the second signal and the receive filter is determined based on the node information.
