Abstract:
1. An integrated circuit comprising: receiver circuitry which, in operation, inputs (a) downlink resource allocation information for a first downlink component carrier and uplink resource allocation information for one or more uplink component carrier(s), both of which are received on the first downlink component carrier, (b) downlink resource allocation information for a second downlink component carrier different from the first downlink component carrier, which is received on the second downlink component carrier, (c) downlink data received on the first downlink component carrier in accordance with the downlink resource allocation information received on the first downlink component carrier, and (d) downlink data received on the second downlink component carrier in accordance with the downlink resource allocation information received on the second downlink component carrier, and transmitter circuitry which, in operation, outputs uplink data to be transmitted on the one or more uplink component carrier(s) in accordance with the uplink resource allocation information received on the first downlink component carrier, wherein a number of the one or more uplink component carrier(s) is less than a number of configured downlink component carriers that include at least the first and second downlink component carriers, and wherein, after the transmitter circuitry in operation outputs the uplink data to be transmitted on the one or more uplink component carrier(s), the receiver circuitry in operation inputs a response signal for the uplink data, the response signal being received on the first downlink component carrier but not on the second downlink component carrier.
