Japanese Patent JP5468070

B2

Provided are a terminal device and a retransmission control method which enable the avoidance of the degradation of transmission characteristics of a response signal and the minimization of the increase of the overhead of an uplink control channel when ARQ is applied in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. In a terminal (200), a control unit (209) transmits a bundle response signal using a resource in a basic region of an uplink control channel in an uplink unit band of a unit band group when no error is detected in each of a plurality of pieces of downlink data of the unit band group, the uplink control channel in the uplink unit band being associated with a downlink control channel in a basic unit band that is a downlink unit band in which a broadcast channel signal including information relating to the uplink unit band is transmitted, and the control unit transmits the bundle response signal using a resource in an additional region of the uplink control channel when an error is detected in each of the plurality of pieces of downlink data.
