Abstract: A method is described for a user equipment (UE) to report channel state information (CSI) including at least one of a rank indicator (RI), a precoding matrix indicator (PMI) or a channel quality indicator (CQI) in a wireless communication system. The UE reports the RI to an evolved Node B (eNB), drops a report of the PMI after reporting the RI to the eNB, and reports the CQI to the eNB after dropping the PMI report. A rank value corresponding to the RI is changed from a rank value corresponding to a most recently reported RI before reporting the RI to the eNB. The CQI is determined based on the RI and a precoding matrix that does not correspond to the dropped PMI report.
