Abstract:
1. A wireless communication apparatus which transmits a radio signal of a first frequency and a radio signal of a second frequency, comprising: information reception unit which receives information indicative of a transmission power of a counterpart apparatus; measuring unit which measures a reception level of a reception signal which is closer to the first frequency than to the second frequency; path loss detection unit which finds a path loss on the basis of the information that is received by the information reception unit and the reception level that is measured by the measuring unit; first determination unit which determines a transmission power of a radio signal of the first frequency on the basis of the path loss that is found by the path loss detection unit; correction value detection unit which finds a difference between a path loss of the first frequency and a path loss of the second frequency; second determination unit which determines a transmission power of a radio signal of the second frequency on the basis of the path loss that is found by the path loss detection unit and the difference in path loss which is found by the correction value detection unit; first transmission unit which transmits the radio signal of the first frequency with the transmission power that is determined by the first determination unit; and second transmission unit which transmits the radio signal of the second frequency with the transmission power that is determined by the second determination unit.
