Abstract: The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of a terminal in a wireless communication system is provided. The method includes receiving, from a first cell of 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 the first cell of the base station, the DCI for scheduling a physical downlink shared channel (PDSCH), the DCI including the CIF; if 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.
