PROBLEM TO BE SOLVED: To prevent transmission power between base stations from being unbalanced due to asynchronization of balance adjustment, when a reception timing of transmission power balance control signals is different caused by dispersion in a transmission delay of the control signals from a control station to each of the base stations, in soft handover in a cellular communication system. SOLUTION: In response to the reception of a control signal, a balance adjustment period is controlled so as to start at a frame with a frame number CFN in which a relation of mod (CFN, m×Nperiod)=L (where m is a natural number, and L is 0 or a natural number smaller than m×Nperiod and is common to all the base stations) is established, where a frame number of a transmission frame to a mobile station is CFN and a balance adjustment period is a Nperiod frame. In this way, a calculation timing of a subsequent balancing period is synchronized between the base stations, and thus, the transmission power between the base stations can be balanced.
