Patent ID: 8369788

Claim:
A method for mitigating inter-cell interference in a multi-cell environment, the method comprising: determining, by a mobile station, at least one precoding matrix index which acts as the strongest or weakest interference for at least one neighboring base station in a specific frequency band; calculating, by the mobile station, a quality of reception signal assuming that the at least one precoding matrix index is coordinated; and transmitting, by the mobile station, the at least one precoding matrix index and the quality of reception signal to a serving base station, wherein the at least one precoding matrix index is transferred from the serving base station to the at least one neighboring base station, wherein other mobile stations, which are served by the serving base station, transmit corresponding precoding matrixes index and quality of reception signals, wherein, when the at least one precoding matrix from the mobile station is in a collision with precoding matrixes from other mobile stations in the serving base station, the quality of reception signal is used for resolving the collision.
