Adaptive interference alignment precoding and decoding to prevent multi-cell interference

A mobile station, comprising:

• an interference determination unit configured to receive a pilot signal from a plurality of base stations and determine an effective interference based on the pilot signal;
• and
• a feedback unit configured to feed back channel information of a channel to a service base station, the channel being between the mobile station and at least one base station transmitting a pilot signal, determined as the effective interference, from among the plurality of base stations,
• wherein the plurality of base stations receives the channel information from a plurality of mobile stations including the mobile station, and transmits the received channel information to a network control apparatus, and the network control apparatus generates beamforming information, associated with an interference alignment, based on a number of effective interferences with respect to the plurality of mobile stations, and transmits the beamforming information to the plurality of base stations.
