Abstract
A base station transmits, to a mobile station, a transmission power control instruction signal for controlling the transmission power of the mobile station, along with a transmission signal, at regular periods, based on a received power of a signal transmitted by the mobile station. The mobile station at its transmission power control bit monitor monitors the transmission power control instruction signal transmitted by the base station and changes the rate of modification in the transmission power in a step size determining unit, based on either the number of consecutive transmission power control instruction signals that give the same content or the number of consecutive transmission power control instruction signals that give different contents, one from another. The mobile station in its transmission power amplifier gain controller controls the transmission power of a signal to be transmitted, based on the transmission power control instruction signal transmitted by the base station and the changed rate of modification in the transmission power.
