The present invention relates to a method for receiving a reference CSI configuration information and a following CSI configuration information which is configured to report a same RI (Rank Indicator) as the reference CSI configuration information, receiving a first precoding codebook subset information for the reference CSI configuration information and a second precoding codebook subset information for the following CSI configuration information, set of RIs according to the second precoding codebook subset information is same as set of RIs according to the first precoding codebook subset information, and transmitting CSI determined based on at least one of the first precoding codebook subset information and the second precoding codebook subset information. |
