    Abstract: Disclosed is a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can he applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. The purpose of the present invention is to efficiently transmit downlink data in a slot in which a synchronization signal block is transmitted and, according to the present invention, a base station in a communication system checks whether a synchronization signal block and downlink data are transmitted in the same slot, determines a downlink data transmission method when the synchronization signal block and the downlink data are transmitted in the same slot, and transmits the downlink data and a demodulation reference signal for the downlink data to a terminal on the basis of the downlink data transmission method, and the downlink data transmission method can be determined on the basis of at least one of the transmission pattern of the synchronization signal block, the relationship between the synchronization signal block and a subcarrier interval applied to the downlink data, and the index of the slot in which the synchronization signal block is to be transmitted.

    Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a terminal is provided. The method performed by a terminal includes receiving, from a base station, DCI scheduling a plurality of PDSCHs on a PDCCH, wherein the DCI includes information on a TDRA and information on a TCI state, identifying symbol offsets between the PDCCH and the plurality of PDSCHs based on the TDRA, in case that a first symbol offset between the PDCCH and a first PDSCH is less than a threshold, receiving, from the base station, the first PDSCH based on a default TCI state, and in case that a second symbol offset between the PDCCH and a second PDSCH is equal to or greater than the threshold, receiving, from the base station, the second PDSCH based on the TCI state.
