<P>PROBLEM TO BE SOLVED: To maintain transmission of an uplink ACK/NACK signal even in a transition period for which an aggregation number of component carriers is increased/decreased by a higher layer signaling. <P>SOLUTION: A user terminal comprises: a reception unit that receives a PDSCH for each CC which constitutes a system band; a demodulation unit 406 that demodulates the PDSCH for the each received CC; an ACK/NACK signal generation unit 418 that generates an uplink ACK/NACK signal according to a demodulation result of the PDSCH by the demodulation unit 406; and a mapping unit 415 that allocates a wireless resource to the uplink ACK/NACK signal for an anchor block using LTE, and allocates a user specific wireless resource to the uplink ACK/NACK signal for other CC. <P>COPYRIGHT: (C)2012,JPO&INPIT |
