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.
