<P>PROBLEM TO BE SOLVED: To provide a mobile terminal device and a radio communication method that are capable of efficiently transmitting feedback control information by a physical uplink control channel. <P>SOLUTION: A mobile terminal device of the present invention parallelly receives downlink shared data channels by plural CCs, determines ACK/NACK/DTX for downlink shared data channel signals, collectively encodes determination results (states) of the plural CCs after the number of states is reduced so that they can be individually notified, and subjects the encoded data to a signal processing to achieve orthogonalization between users and then transmits the data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
