In a mobile communication system, broadcast information is transmitted from a radio base station to a mobile station. A transmission power calculation unit calculates the transmission power for transmitting resending data frames from the radio base station to the mobile station by a unicast transmission method. The transmission power calculation unit further calculates the transmission power for transmitting broadcast information from the radio base station to the mobile station by a broadcast transmission method such that the sum of the calculated transmission power and the transmission power for transmitting broadcast information from the radio base station to the mobile station by the broadcast transmission method is minimized. A transmission section of the radio base station transmits the broadcast information to the mobile station by the broadcast transmission method at the calculated transmission power. |
