A base station includes a received signal power measurement unit that calculates a radio signal power of a radio signal received from a mobile station which is connected by radio connection, a measurement period decision unit that decides a measurement period which is used for calculating an interference power based on a first index representing a transmission rate of received data transmitted from the mobile station and one of a second index representing a resource assigned to the mobile station and a third index representing an amount of data buffered in the mobile station and to be transmitted, an interference power measurement unit that calculates an interference power over the decided measurement period, a received signal quality measurement unit that calculates signal quality of the radio signal received from the mobile station based on the radio signal power and the interference power and a transmission power decision unit that decides a transmission power control value to the mobile station based on the signal quality. |
