METHOD AND APPARATUS FOR CONTROLLING RI REPORT |
摘要 |
The present invention relates to a method and an apparatus for controlling a rank information (RI) report. According to an embodiment of the present invention, a method for controlling an RI report of a User Equipment (UE) in a base station of a Long Term Evolution (LTE) mobile communications network is provided. The method includes the following steps: determining a Channel State Information (CSI) report set for a UE, where the CSI report set includes multiple CSI feedback modes (CSI processes); sending to the UE Radio Resource Control (RRC) signaling indicating the CSI report set; and sending to the UE signaling indicating a precoding codebook subset and/or rank restriction of each CSI feedback mode in the CSI report set. According to the above embodiment, rank selection and high rank transmission are supported for coordinated multi-point (CoMP) transmission in the LTE mobile communications network. |
