Methods and apparatuses for performing wireless communication are provided. In some embodiments, a method performed by a terminal of a wireless communication system, includes receiving, from a base station of the wireless communication system, cross-carrier scheduling configuration information; identifying whether the cross-carrier scheduling configuration information for a secondary cell (SCell) comprises a carrier indicator field (CIF) presence field; receiving, from the base station, downlink control information for another cell on the SCell based on identifying that the cross-carrier scheduling configuration information comprises the CIF presence field; and receiving, from the base station, data using the another cell according to the downlink control information, wherein the cross-carrier scheduling configuration information indicates a CIF value of the SCell when the CIF presence field is configured for two or more cells.
