1. A communication apparatus comprising:
a receiver, which, in operation, (a) receives first downlink resource allocation information for a first downlink component carrier, (b) receives second downlink resource allocation information for a second downlink component carrier, which is different from the first downlink component carrier, (c) receives first downlink data on the first downlink component carrier in accordance with the first downlink resource allocation information, (d) receives second downlink data on the second downlink component carrier in accordance with the second downlink resource allocation information, and (e) receives uplink resource allocation information for uplink component carriers on only one out of the first downlink component carrier and the second downlink component carrier; and
a transmitter, which, in operation, transmits uplink data on the uplink component carriers in accordance with the uplink resource allocation information,
wherein the receiver, in operation, receives an Acknowledgement/Negative-acknowledgement (ACK/NACK) signal for the uplink data only said one downlink component carrier on which the uplink resource allocation information is received.
