摘要： A communication system may include a serving base station and neighboring base stations. Each of the serving base station and the neighboring base stations may have a corresponding user group. Terminals belonging to a particular user group may feed back information associated with interference channels, and reasonably generate a precoding matrix. Through this, it is possible to perform an accurate interference alignment and to enhance a throughput. In this instance, terminals belonging to the other user groups may feed back information associated with a throughput, and a corresponding base station may perform the interference alignment using a user selection resulting in decreased overhead.
