Abstract:
1. A base station that configures a plurality of component carriers for a mobile station and communicates with the mobile station using at least one of the plurality of component carriers, comprising: a signal generation section that determines a bandwidth for power headroom calculation used by the mobile station to calculate a power headroom representing a transmission power reserve capacity of the mobile station in component carriers with no uplink allocation control signal allocated, and generates a notification signal containing information on the determined bandwidth for power headroom calculation; a transmitting section that transmits the generated notification signal to the mobile station, and an estimation section that estimates a path-loss level between the mobile station and the base station, wherein: the signal generation section determines a bandwidth for power headroom calculation used by the mobile station based on a correlation between N types (N is a natural number) of path-loss level candidates and bandwidths for power headroom calculation corresponding to the respective path-loss level candidates, and the estimated path-loss level.
