A method for receiving periodic channel information by a base station in a wireless communication system which supports carrier aggregation, the method comprising: setting a higher-layer signal including physical uplink shared channel, PUSCH, operation mode information, wherein the PUSCH operation mode information indicates whether a PUSCH operation mode is set to transmit, in one sub-frame corresponding to a serving cell in a carrier aggregation scheme, periodic channel information for multiple serving cells of the carrier aggregation scheme from a terminal to the base station; transmitting, to the terminal, the higher-layer signal, wherein the higher-layer signal is defined as a parameter being zero if the PUSCH operation mode is not set, and wherein said parameter is one, if the PUSCH operation mode is set; identifying whether transmission time instants of channel information for two or more serving cells of the multiple serving cells coincide with each other in the one sub-frame, if it is identified that the PUSCH operation mode is set to the terminal by the higher-layer signal; receiving, from the terminal, channel information for the two or more serving cells in the one sub-frame on a PUSCH according to the PUSCH operation mode being activated, if it is identified that transmission time instants of channel information for the two or more serving cells coincide with each other in the one sub-frame; and receiving, from the terminal, channel information for one serving cell of the multiple serving cells on a physical uplink control channel, PUCCH, if it is identified that there are not two or more serving cells of the multiple serving cells such that the transmission time instants of their corresponding channel information coincide with each other in the one sub-frame. setting a higher-layer signal including physical uplink shared channel, PUSCH, operation mode information, wherein the PUSCH operation mode information indicates whether a PUSCH operation mode is set to transmit, in one sub-frame corresponding to a serving cell in a carrier aggregation scheme, periodic channel information for multiple serving cells of the carrier aggregation scheme from a terminal to the base station; transmitting, to the terminal, the higher-layer signal, wherein the higher-layer signal is defined as a parameter being zero if the PUSCH operation mode is not set, and wherein said parameter is one, if the PUSCH operation mode is set; identifying whether transmission time instants of channel information for two or more serving cells of the multiple serving cells coincide with each other in the one sub-frame, if it is identified that the PUSCH operation mode is set to the terminal by the higher-layer signal; receiving, from the terminal, channel information for the two or more serving cells in the one sub-frame on a PUSCH according to the PUSCH operation mode being activated, if it is identified that transmission time instants of channel information for the two or more serving cells coincide with each other in the one sub-frame; and receiving, from the terminal, channel information for one serving cell of the multiple serving cells on a physical uplink control channel, PUCCH, if it is identified that there are not two or more serving cells of the multiple serving cells such that the transmission time instants of their corresponding channel information coincide with each other in the one sub-frame.
