Method for eliminating interference in multi-node system and terminal using method thereof

摘要

An interference elimination method performed by a first terminal in a multi-node system and an apparatus for the same are provided. The method includes receiving information from a node related to a second precoding matrix that is applied to a second signal to be transmitted to a second terminal; receiving a first signal to which a first precoding matrix is applied from the node; and eliminating an interference signal contained in the first signal based on the information on related to the second precoding matrix.

1. A method of removing interference, the method performed by first User Equipment (UE) in a multi-node system and comprising:
receiving information from a node, the information related to a second precoding matrix applied to a second signal transmitted to a second UE; receiving a first signal to which a first precoding matrix has been applied from the node; and removing an interference signal included in the first signal based on the information related to the second precoding matrix, wherein the interference signal is a product of the second signal and a channel matrix between the node and the first UE, wherein the information related to the second precoding matrix comprises a precoding row vector in the second precoding matrix for a transmit antenna that exerts interference on the first UE.
