A terminal device configured to communicate with a base station apparatus, the terminal device comprising: a reception unit configured to receive at least three of first information indicating a first uplink-downlink configuration, second information indicating a second uplink-downlink configuration, third information indicating a third uplink-downlink configuration, and fourth information indicating a special subframe configuration; and a transmission unit configured to perform, based on the first uplink-downlink configuration indicated by the first information, a transmission on a physical uplink shared channel, the transmission on the physical uplink shared channel being based on a detection of a transmission on a physical downlink control channel, and perform, based on the second uplink-downlink configuration indicated by the second information, a transmission of a hybrid automatic repeat request, HARQ, information on a physical uplink control channel, the transmission of the HARQ information on the physical uplink control channel being based on a detection of a transmission on a physical downlink shared channel, wherein in a case that the terminal device is not configured with the second information indicating the second uplink-downlink configuration, a downlink pilot time slot, DwPTS, of a first special subframe is determined based on the first uplink-downlink configuration indicated by the first information, and whether the transmission on the physical downlink shared channel in the DwPTS of the first special subframe is performed or not is defined based on the special subframe configuration indicated by the fourth information and a cyclic prefix for a downlink, and in a case that the terminal device is configured with the second information indicating the second uplink-downlink configuration, a DwPTS of a second special subframe is determined based on the third uplink-downlink configuration indicated by the third information, and whether the transmission on the physical downlink shared channel in the DwPTS of the second special subframe is performed or not is defined based on the special subframe configuration indicated by the fourth information and the cyclic prefix for the downlink. a reception unit configured to receive at least three of first information indicating a first uplink-downlink configuration, second information indicating a second uplink-downlink configuration, third information indicating a third uplink-downlink configuration, and fourth information indicating a special subframe configuration; and first information indicating a first uplink-downlink configuration, second information indicating a second uplink-downlink configuration, third information indicating a third uplink-downlink configuration, and fourth information indicating a special subframe configuration; and a transmission unit configured to perform, based on the first uplink-downlink configuration indicated by the first information, a transmission on a physical uplink shared channel, the transmission on the physical uplink shared channel being based on a detection of a transmission on a physical downlink control channel, and perform, based on the second uplink-downlink configuration indicated by the second information, a transmission of a hybrid automatic repeat request, HARQ, information on a physical uplink control channel, the transmission of the HARQ information on the physical uplink control channel being based on a detection of a transmission on a physical downlink shared channel, wherein perform, based on the first uplink-downlink configuration indicated by the first information, a transmission on a physical uplink shared channel, the transmission on the physical uplink shared channel being based on a detection of a transmission on a physical downlink control channel, and perform, based on the second uplink-downlink configuration indicated by the second information, a transmission of a hybrid automatic repeat request, HARQ, information on a physical uplink control channel, the transmission of the HARQ information on the physical uplink control channel being based on a detection of a transmission on a physical downlink shared channel, wherein in a case that the terminal device is not configured with the second information indicating the second uplink-downlink configuration, a downlink pilot time slot, DwPTS, of a first special subframe is determined based on the first uplink-downlink configuration indicated by the first information, and whether the transmission on the physical downlink shared channel in the DwPTS of the first special subframe is performed or not is defined based on the special subframe configuration indicated by the fourth information and a cyclic prefix for a downlink, and in a case that the terminal device is configured with the second information indicating the second uplink-downlink configuration, a DwPTS of a second special subframe is determined based on the third uplink-downlink configuration indicated by the third information, and whether the transmission on the physical downlink shared channel in the DwPTS of the second special subframe is performed or not is defined based on the special subframe configuration indicated by the fourth information and the cyclic prefix for the downlink.
