Abstract: The present invention relates to a method and an apparatus for receiving, in a wireless communication system supporting carrier aggregation and usage change of a radio resource, a signal of a terminal which does not support simultaneous reception and transmission of aggregated cells. Specifically, the method comprises the steps of: receiving downlink control information for a secondary cell on a specific radio resource corresponding to a special subframe of a primary cell and a downlink subframe of the secondary cell; and determining validity of the downlink control information according to an uplink-downlink setting of the primary cell, wherein the downlink control information is determined to be invalid if the primary cell is in non-fallback mode, and determined to be valid if the primary cell is a time division duplex (TDD) uplink-downlink setting according to fallback mode and the secondary cell is cross-carrier scheduled according to the primary cell.
