Title:
MOBILE TERMINAL APPARATUS AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/023552
Kind Code:
A1
Abstract:
The objective of the invention is to efficiently transmit feedback control information over a physical upstream control channel in a communication system having a system band constituted by a plurality of fundamental frequency blocks. There are included a demodulation unit that demodulates a downlink shared channel signal for each of a plurality of fundamental frequency blocks; a determination unit that determines, on the basis of the downlink shared channel signal as demodulated, a state of a retransmission response signal for each of the plurality of fundamental frequency blocks; and an uplink control channel processing unit that maps the retransmission response signals of the plurality of fundamental frequency blocks to the uplink control channel of a particular fundamental frequency block selected from the plurality of fundamental frequency blocks. The uplink control channel processing unit selects a plurality of allocated resources from the uplink control channel, and specifies the states of the retransmission response signals of the plurality of fundamental frequency blocks by use of channel selection information and bit information using phase shift modulation.
