1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, cross carrier scheduling configuration including information indicating that a carrier indicator field (CIF) is included in downlink control information (DCI);
receiving, from a first cell of the base station, the DCI for scheduling a physical downlink shared channel (PDSCH), the DCI including the CIF;
in case that the CIF indicates that a resource assignment of the PDSCH is for the first cell, identifying whether a first offset value between a reception of the DCI and the PDSCH is less than a threshold; and
in case that the first offset value is less than the threshold and the terminal supports default beam selection for the PDSCH, receiving, from the first cell of the base station, data on the PDSCH based on quasi co-located (QCL) parameters for a control resource set (CORESET) associated with a search space with a lowest CORESET identifier (ID) within an active bandwidth part (BWP) of the first cell in a latest slot monitored by the terminal.
