Classification: CPC H  Y | IPC H

Claim 0:
1. A communication apparatus comprising:
circuitry which, in operation, generates a power status report of the communication apparatus in a communication system using component carrier aggregation, in which two or more component carriers (CCs) are aggregated, wherein the power status report includes: (i) a CC specific maximum transmission power, PCMAX,c, for each configured and activated uplink CC, wherein PCMAX,c shall be set within following bounds:

PCMAX_L,c<=PCMAX,c<=PCMAX_H,c, where PCMAX_L,c is a lower bound and PCMAX_H,c is a higher bound of a CC specific maximum transmission power, and (ii) a power headroom report indicative of a difference between the CC specific maximum transmission power, PCMAX,c, and an estimated communication apparatus transmit power, per each configured and activated uplink CC,
wherein the CC specific maximum transmission power, PCMAX,c, for each configured and activated CC is included in the power status report when a resource is allocated to the configured and activated uplink CC for the communication apparatus; and
a transmitter configured to transmit the power status report to the base station.
