The present 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 present 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 and an apparatus for performing same. The method includes: receiving configuration information of a physical downlink control channel (PDCCH) from a base station; monitoring downlink control information (DCI) having a specific format in a slot, the monitoring based on the configuration information of the PDCCH; determining whether a number of physical downlink shared channels (PDSCHs) received based on the DCI having the specific format in the slot is a number based on a PDSCH reception capability of the terminal; and in case that the number of the PDSCHs received based on the DCI having the specific format is the number based on the PDSCH reception capability of the terminal, stopping monitoring DCI having the specific format in the slot.
