  • Terminal apparatus and retransmission control method
    Patent number: 10455516
    Abstract: 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.
    Type: Grant
