1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving a cross carrier scheduling configuration for a primary cell (PCell) comprising a serving cell index and information indicating a carrier indicator field (CIF) value used in a scheduling cell;
receiving a cross carrier scheduling configuration for a secondary cell (SCell) comprising information about the scheduling cell, the information about the scheduling cell comprising a CIF presence field;
receiving downlink control information (DCI) on the SCell, the DCI comprising a bandwidth part (BWP) identity (ID) and a carrier indicator indicating the PCell; and
performing BWP switching to a BWP corresponding to the BWP ID for the PCell based on the DCI received from the SCell.
