<P>PROBLEM TO BE SOLVED: To efficiently transmit feedback control information in a physical uplink control channel in a communication system having a system band composed of a plurality of fundamental frequency blocks. <P>SOLUTION: A mobile terminal device comprises: a demodulation part demodulating a downlink shared channel signal of each of a plurality of fundamental frequency blocks; a determination part determining a state of a retransmission response signal of each of the plurality of fundamental frequency blocks based on the demodulated downlink shared channel signal; and an uplink control channel processing part mapping the retransmission response signals of the plurality of fundamental frequency blocks to an uplink control channel of a specific fundamental frequency block selected from the plurality of fundamental frequency blocks. The uplink control channel processing part selects a plurality of allocation resources from the uplink control channel and stipulates states of the retransmission response signals of the plurality of fundamental frequency blocks by bit information by phase shift modulation and channel selection information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
