Provided is a signal transmission method of a multi-node system employing a plurality of nodes and a base station that can control each of the plurality of nodes. The method includes: transmitting per-node transmission information to a user equipment; transmitting at least one stream to the user equipment by applying a precoding matrix determined for each node in at least one node among the plurality of nodes; and receiving per-node feedback information from the user equipment, wherein the per-node feedback information includes information on a precoding matrix applicable to a node which transmits the at least one stream.
