Abstract
A method for reducing interferences between base stations in a communication system having a plurality of base stations. This method comprises the steps of: causing a user station to receive both a signal transmitted by a local-cell base station and a signal transmitted by an adjacent-cell base station, thereby measuring the SNR of the interfered link and the SNR of the leak link of the adjacent-cell base station; calculating a weighting factor of a leak power based on the measured SNR of the interfered link and the measured SNR of the leak link of the adjacent-cell base station; and determining, based on the calculated weighting factor, whether or not the leak power has to be suppressed and to what degree such suppression has to be performed.
