<p>The purpose of the present invention is to feedback pieces of CSI related to each transmission point, when CoMP transmission is applied in a carrier aggregation framework. This wireless communication method is for a wireless communication system provided with: a plurality of wireless base station devices; and a user terminal configured so as to be capable of coordinated multipoint transmission and reception with respect to the plurality of wireless base station devices. The wireless communication method is characterized in that, in the wireless base station devices, when CoMP transmission is applied, CSI set information of sets including at least one piece of CSI is subjected to higher layer signaling, and CSI request information in DCI is transmitted, and, in the user terminal, CSI is fed back on the basis of the CSI set information and the CSI request information.</p> |
