The disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to an intelligent service (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. A method is provided for receiving a CSI-RS in a communication system, which includes acquiring, by a UE, from a base station, a configuration for a resource set including a resource set identifier, information for at least one CSI-RS resource, and repetition information, wherein a number of the at least one CSI-RS resource is up to a maximum number of CSI-RS resources per resource set, the repetition information is set as either on or off, and the at least one CSI-RS resource within the resource set is regarded to be transmitted in different OFDM symbols in case that the repetition information is set as on; and transmitting, to the base station, CSI based on the configuration for the resource set.
