A method for transmitting a physical channel in a Time Division Duplex (TDD) communication system capable of carrier aggregation is provided for supporting aggregation of carriers having different TDD configurations. The communication method of a terminal in a TDD radio communication system accomplishing broadband through carrier aggregation of primary and secondary cells, of which aggregated carriers have different TDD Uplink-Downlink (UL-DL) configurations, includes receiving Physical Downlink Shared Channel (PDSCH) through the secondary cell, and transmitting acknowledgement information corresponding to the PDSCH to a base station, where acknowledgement information is transmitted on a Physical Uplink Control CHannel (PUCCH) of the primary cell.
