Abstract

See full text

Optimal transmit power control is performed in a band other than licensed bands. When the way of specifying transmit power differs between the licensed band and a frequency band other than the licensed band, the expression of the transmit power control is changed to perform transmit power control. A terminal apparatus includes a carrier aggregation radio transmission unit configured to simultaneously transmit a plurality of component carriers, and a transmit power control unit configured to control transmit power of each of the plurality of component carriers, wherein the transmit power control unit calculates a transmit power of a dedicatedly usable first component carrier among the plurality of component carriers in consideration of the transmit power of the first component carrier, and calculates a transmit power of a second component carrier other than the dedicatedly usable first component carrier in consideration of the transmit power of the first component carrier.
