Abstract: A method and apparatus are provided for reporting Channel State Information (CSI) for operation of a network, when a Precoding Matrix Indicator (PMI) and a Channel Quality Indicator (CQI) cannot be calculated. The method includes reporting a first Precoding Matrix Indicator (PMI); detecting that a Rank Indicator (RI) is changed before a second PMI is reported, the RI being changed within an RI group; calculating the second PMI and a Channel Quality Indicator (CQI) using the first PMI; and reporting the second PMI and the CQI.
