摘要
<p>Disclosed is a method and apparatus for transmitting channel state information (CSI) by a user equipment in a mobile communication system. The method includes receiving a CSI-reference signal (CSI-RS) for measuring a state of a downlink channel and a CSI feedback-related configuration from a base station (BS); determining a channel quality indication (CQI) for at least one transmission point and control information for determining a CQI for multiple transmission points, based on the received CSI-RS and CSI feedback-related configuration; and transmitting the determined CQI for the at least one transmission point and control information to the BS.</p>
