Abstract
A reception unit measures a reception power level of a reference signal which is received from a base station apparatus BS. A reception signal processing unit acquires information indicative of a transmission power level of the reference signal. A control unit finds a path loss on the basis of the reception power level and this information. The control unit determines, on the basis of the path loss, a transmission power level of that one of two transmission frequency bands, which is closer to a frequency band with respect to which the pass loss has been measured. The control unit determines a transmission power level of the other transmission frequency band, which is farther from the frequency band with respect to which the pass loss has been measured, by correcting the transmission power level on the basis of a correction value based on a difference in frequency.
