TERMINAL DEVICE, BASE STATION DEVICE, INTEGRATED CIRCUIT, AND COMMUNICATION METHOD

摘要

This terminal device that communicates with a base station device is provided with a transmission unit that, on the basis of a UL-DL setting indicated by second information, uses a physical uplink control channel to transmit a HARQ-ACK corresponding to the detection of transmission in a physical downlink shared channel, and when a physical uplink control channel format (3) is set with respect to the transmission of the HARQ-ACK, whether a special subframe that is on the basis of the UL-DL setting indicated by the second information is excluded from the HARQ-ACK codebook size determination is stipulated on the basis of a downlink cyclic prefix and the setting of a special subframe that is on the basis of fourth information.
