Method and apparatus for channel status information feedback in mobile communication system
A communication method and a 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) are provided. 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 and an apparatus for transmitting cell status information (CSI) in a mobile communication system are provided. The method includes receiving configuration information for a plurality of channel status information reference signals (CSI-RSs), generating feedback information by measuring at least one of the CSI-RSs based on priority information, and transmitting the feedback information. The priority information is associated with a non-precoded CSI-RS, a cell-specific beamformed CSI-RS and a user equipment (UE)-specific beamformed CSI-RS.
