Method for transceiving signal in multi-node system, and device therefor

A terminal of a multi-node system, comprising:

• a Radio Frequency (RF) unit transmitting and receiving radio signals;
• and
• a processor connected to the RF unit and generating the radio signals,
• wherein the processor receives reference signal configuration information from a first node, receives a reference signal from a second node, measures interference due to the second node based on the reference signal, generates interference node information, and transmits the interference node information to the first node or the second node,
• wherein the reference signal configuration information comprises information about mapping between the second node and the reference signal, and
• the interference node information comprises an index of the reference signal.
