Abstract
A communications apparatus includes a receiving unit which receives a data channel for each predetermined transmission period; a determining unit which determines, for each data channel, acknowledgement information which indicates an acknowledgement or a non-acknowledgement; a generating unit which generates a control channel including the acknowledgement information; and a transmitting unit which transmits the control channel. For first and second data channels received during at least successive first and second transmission periods, the first and second acknowledgement information is provided. The second control channel which includes both the first and the second acknowledgement information which includes both the first and the second acknowledgement information is transmitted after a first control channel which includes the first acknowledgement information.
