1. A method for receiving control information by a terminal for which multiple component carrier groups are configured in a wireless communication system, the method comprising:receiving, from a base station, configuration information on transmission of first downlink control information (DCI), wherein the configuration information comprises a transmission period and a transmission offset of the first DCI;
receiving, from the base station, the first DCI, wherein the first DCI comprises common scheduling information for data for a component carrier group including one or more component carriers;
receiving, from the base station, second DCI, wherein the second DCI comprises specific scheduling information for the data for one of the one or more component carriers respectively; and
attempting to detect the common scheduling information in the first DCI and the specific scheduling information in the second DCI using the configuration information.
