Abstract: 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.

Abstract: A control channel transmission/reception method and apparatus is provided. The base station of the present invention transmits configuration information on a control channel to a terminal, checks an aggregation level for use in transmitting the control channel, maps Demodulation Reference Signal (DMRS) to resource elements in a resource block depending on the aggregation level, determines, when the resource elements of the DMRS correspond to a first resource element set, whether to map the DMRS to resource elements corresponding to a second resource element set in the resource block, and transmits the DMRS and control channel to the terminal according to the determination result.
