<p>The present invention relates to a method for processing channel state information (CSI), a base station and a terminal. The method for processing channel state information includes: a base station configuring a plurality of CSI processes for a terminal, each CSI process at least including information of a channel measurement part and information of an interference measurement part; when the base station configures corresponding CSI reference processes for partial or all CSI processes, at least limiting a rank indicator (RI) of the CSI processes for calculating a CSI report to be consistent with an RI of the CSI reference processes by configuring the CSI reference processes; and for the CSI processes configured with the CSI reference processes, the base station receiving the CSI report of the CSI processes according to the RI, or the RI and a PTI, or the RI and a PMI0 corresponding to the CSI reference processes. The embodiments of the present invention can realize flexible channel state information configuration and feedback, thereby effectively reducing the uplink feedback overhead and the possible collision probability of feedback information.</p> |
