Abstract
The present invention relates to a method and an apparatus for controlling a Channel State Information (CSI) report. According to an embodiment of the present invention, a method for controlling a CSI report of a User Equipment (UE) in a base station of a Long Term Evolution (LTE) mobile communication network is provided. The method includes a step of determining a CSI report set for a UE, where the CSI report set includes multiple CSI feedback modes, and each CSI feedback mode is defined to include a Non-Zero Power Reference Signal (NZP RS) resource part for channel measurement and an Interference Measurement Resource (IMR) part for interference measurement. In addition, the method further includes a step of sending to the UE Radio Resource Control (RRC) signaling indicating the CSI report set.
