1. A communication apparatus, for which a first downlink component carrier, a second downlink component carrier, and an uplink component carrier are configured, the communication apparatus comprising:
circuitry, which, in operation, generates a first downlink control signal with a first payload size and a second downlink control signal with a second payload size,
wherein the first downlink control signal includes first resource allocation information related to one of the uplink component carrier and the first downlink component carrier, and the second downlink control signal includes second resource allocation information related to the second downlink component carrier; and
a transmitter, which is coupled to the circuitry and which, in operation, transmits the first downlink control signal over the first downlink component carrier and transmits the second downlink control signal over the second downlink component carrier;
wherein, the first payload size is determined based on a larger one of a number of information bits related to the first downlink component carrier and a number of information bits related to the uplink component carrier; and
wherein, the second payload size is determined based on a number of information bits related to the second downlink component carrier.
