Abstract: A transmit node receives a transformed correlation matrix or a correlation matrix of a channel coefficient matrix, or a correlation matrix of an interference channel coefficient matrix from each of receive nodes sharing a radio resource. The transmit node determines a precoder based on a value maximizing values determined by the transformed correlation matrix or the correlation matrix of the channel coefficient matrix, or a value minimizing values determined by the correlation matrix of the interference channel coefficient matrix, and precodes a transmit signal by using the determined precoder.

Abstract: A precoding method and apparatus are provided. Each transmission node receives feedback on first information as information regarding a transmission node that transmits an interference signal causing an interference-to-noise ratio (INR) greater than a first reference value from reception nodes, determines a group to which each transmission node belongs on the basis of the first feedback information, and allocates resources to each group. In a detailed manner, each transmission node determines comparison values of INRs, as two or more values, determines a group by using feedback information corresponding thereto, and allocates resources. Each transmission node receives feedback on channel information or precoder information from reception nodes of each group to which each transmission node belongs, and determines a precoder by using the feedback channel information or precoder information.
