Claim:
1. A User Equipment (UE) for transmitting information to an evolved Node B (eNB), the UE comprising: operation controlling circuitry that determines a Time-Division Duplexing (TDD) uplink-downlink (UL-DL) configuration of each serving cell, wherein the TDD UL-DL configurations of at least two configured serving cells are not the same; and a transmitter that transmits Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) information in a subframe n based on a first feedback factor B in a case of a transmission of the HARQ-ACK information in the subframe n on a Physical Uplink Shared Channel (PUSCH) transmission adjusted based on the detected DCI format 0/4 for the c-th serving cell with the DAI for determining the parameter W in a case of the transmission of the HARQ-ACK information in the subframe n on the PUSCH transmission adjusted based on the detected DCI format 0/4 for the c-th serving cell without a value for the parameter W the subframe n corresponds to a subframe n−k for the c-th serving cell on a Physical Downlink Shared Channel (PDSCH), and it is determined, for each serving cell, whether or not the DCI format 0/4 for the each serving cell includes the DAI based on a configuration of the each serving cell.
