Abstract: 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 by which a terminal receives a signal in a mobile communication system, according to one embodiment of the present specification, comprises the steps of: receiving channel state information-reference signal (CSI-RS) mode information; and receiving a signal on the basis of the CSI-RS mode information. Unlike a conventional method of allowing a base station to periodically set the CSI-RS in a terminal at a predetermined position such that the terminal receives the CSI-RS and generates and reports channel state information, the present invention proposes a method by which a base station allocates, to a terminal, a reference signal transmission for enabling aperiodic generation of the channel state information for a system having various numbers of transmission antenna ports such as one, two, four, eight, twelve, sixteen or thirty-two transmission antenna ports, and receives the channel state information report. In addition, a method for transferring ZP CSI-RS and quasi co-location (QCL) information for supporting rate matching thereby is also proposed.
