A terminal apparatus and retransmission control method reduces 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. 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 will not transmit a response signal to the base station in certain cases.
A terminal that communicates with a base station using a unit band group comprising a plurality of downlink unit bands and uplink unit bands, the plurality of downlink unit bands comprising a downlink base unit band and a downlink non-base unit band, the unit band group comprising control information, the terminal comprising:
A method in a terminal that communicates with a base station using a unit band group comprising a plurality of downlink unit bands and uplink unit bands, the plurality of downlink unit bands comprising a downlink base unit band a downlink non-base unit band, the unit band group comprising control information, the method comprising:
