Patent ID: 11343041

Abstract:
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. The method includes acquiring, by a UE, 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, and the repetition information is set as either on or off; acquiring, by the UE from, a CSI-RS resource configuration per CSI-RS resource including a CSI-RS resource identifier, information for a number of CSI-RS ports, and information for an OFDM symbol for the CSI-RS, wherein the number of the CSI-RS ports of the at least one CSI-RS resource within the resource set is 1 or 2, 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 CSI based on the configuration for the resource set.
