The present disclosure provides a method for reporting channel state information (CSI), a first set of channel state information-reference signals (CSI-RSs) sent from a base station is measured to obtain a first set of CSI, and the first set of CSI obtained is reported to the base station. A second set of CSI-RSs sent from the base station is measured based on the first set of CSI to obtain a second set of CSI, and the second set of CSI obtained is reported to the base station, in which the second set of CSI-RSs is precoded CSI-RSs determined based on the first set of CSI.
