METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING FEEDBACK INFORMATION IN A MOBILE COMMUNICATION SYSTEM

摘要

A method and user equipment for transmitting channel state information (CSI) are provided. The method includes identifying a first CSI configuration with a first information for a period and an offset; identifying a second CSI configuration with a second information for a period and an offset; generating a first CSI for the first CSI configuration, the first CSI including at least one of a rank indicator (RI), a channel quality indicator (CQI), a precoding matrix indicator (PMI), and a precoding type indicator (PTI); generating a second CSI for the second CSI configuration, the second CSI including at least one of a RI, a CQI, a PMI, and a PTI; and reporting a CSI for a CSI configuration among the first CSI configuration and the second CSI configuration based on a type of the CSI, in case of collision between report of the first CSI for the first CSI configuration and report of the second CSI for the second CSI configuration, wherein a type of a CSI with wideband CQI has lower priority than a type of a CSI with RI.
