Title:
TERMINAL APPARATUS AND RETRANSMISSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2010/122783
Kind Code:
A1
Abstract:
A terminal apparatus and retransmission control method which can reduce the overhead of the uplink control channel in cases when ARQ is applied in communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. Here, a first condition is set in which downlink assignment control information is transmitted from a base station by a unit band group which comprises a basic unit band, which is the downlink unit band on which a broadcast channel signal including information relating to the uplink unit band is transmitted, and a second downlink unit band other than the basic unit band. A bundling unit (213) will not transmit a response signal to the base station (100) in cases when the first condition is satisfied and a control information receiving means has failed in receiving all of the downlink assignment control information transmitted by the basic unit band and second downlink unit band, and in cases when the first condition is satisfied and the control information receiving means has succeeded in receiving only the downlink assignment control information transmitted by the second downlink unit band.
