摘要: Efficient transmission control of power headroom is performed by a mobile station apparatus that includes unit which manages difference between maximum transmit value determined for each uplink carrier component base and predetermined estimated transmission. A path loss measurement monitors downlink informed from the among plurality components. When any changes more than value, modifies to corresponding all components set apparatus.
