To maintain communications of uplink ACK/NACK signals even for a transition period during which the number of aggregated component carriers is added/removed by higher layer signaling, it is a feature providing a reception section that receives the PDSCH for each of CCs that constitute the system band, a demodulation section (406) that demodulates the received PDSCH of each of CCs, an ACK/NACK signal generating section (418) that generates an uplink ACK/NACK signal in response to a demodulation result of the PDSCH in the demodulation section (406), and a mapping section (415) that allocates radio resources to an uplink ACK/NACK signal of the anchor block using LTE, while allocating user-specific radio resources to uplink ACK/NACK signals of the other CCs. |
