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