    Abstract: An interference removal method in a multi-node system is provided. A user equipment (UE) receives node information from a base station, a first signal from a first node, and a second signal from a second node. The first signal and the second signal are used to remove an interference. The node information includes configuration information related to the first signal and the second signal. The configuration information includes information related to at least one of a number of antenna ports of the first node and the second node, a number of data streams, and a node identifier (ID).
