Abstract
Provided is a mobile communication system capable of reducing interference in uplinks and downlinks to achieve excellent communication quality. A mobile station receives cell selection reference signals from a first base station and a second base station to connect before and after a handover, and measures received power values of the cell selection reference signals. The mobile station acquires uplink transmitted power values from the mobile station to the first base station and to the second base station. The first base station and the second base station control a power of the cell selection reference signal so that the uplink transmitted power values from the mobile station to the first base station and to the second base station become substantially equal and so that a received power value at the mobile station of the cell selection reference signal becomes substantially equal to a predetermined reference power value.
