    • The present invention relates to a wireless communication system, and more specifically, to a method and a device for reporting channel state information. According to one embodiment of the present invention, a method for allowing a terminal to report channel state information (CSI) in a wireless communication system comprises the steps of: reporting a rank indicator (RI); dropping a report of a precoding matrix indicator (PMI) after the RI has been reported; and reporting a channel quality indicator (CQI) after the PMI report has been dropped. Here, a rank value corresponding to the RI may be a changed rank value compared to a rank value corresponding to the most recently reported RI before the RI report. Furthermore, the CQI can be determined on the basis of another precoding matrix, rather than a precoding matrix corresponding to the dropped PMI.
    • 无线通信系统技术领域本发明涉及一种无线通信系统,更具体地,涉及用于报告信道状态信息的方法和装置。 根据本发明的一个实施例,一种允许终端在无线通信系统中报告信道状态信息(CSI)的方法包括以下步骤:报告秩指示符(RI); 在RI报告之后丢弃预编码矩阵指标(PMI)的报告; 并在PMI报告丢弃之后报告信道质量指示符(CQI)。 这里,对应于RI的等级值可以是与RI报告之前的最近报告的RI对应的等级值相比较的改变的秩值。 此外,可以基于另一个预编码矩阵来确定CQI,而不是与丢弃的PMI相对应的预编码矩阵。
