Abstract:
1. A method of a terminal transmitting and receiving signals in a multi-node system, the method comprising: receiving reference signal configuration information from a first node; receiving a reference signal from a second node; measuring interference due to the second node based on the reference signal and generating interference node information; and transmitting the interference node information to the first node, wherein the reference signal configuration information comprises information about mapping between the second node and the reference signal, wherein the interference node information comprises an index of the reference signal, wherein the interference node information further comprises a cell identifier (ID) of the second node, and wherein the interference node information comprises an index of at least one transmission antenna that generates interference, from among a plurality of transmission antennas, if the second node comprises a plurality of transmission antennas.
