Abstract
The present disclosure provides a method in a base station for Channel State Information (CSI) process configuration and an associated base station. The method comprises: setting CSI process information for a User Equipment (UE) supporting three dimensional (3D) Multiple Input Multiple Output (MIMO), the CSI process information including at least an index of a CSI Reference Signal Resource (CSI-RS-R) for a vertical direction of a 3D MIMO antenna array; and transmitting the set CSI process information to the UE. Also disclosed are a method in a UE for CSI feedback and an associated UE. The method comprises: receiving CSI process information from a base station, the CSI process information including at least an index of a CSI Reference Signal Resource (CSI-RS-R) for a vertical direction of a three dimensional (3D) Multiple Input Multiple Output (MIMO) antenna array; measuring a CSI Reference Signal (CSI-RS) transmitted from the base station over the CSI-RS-R configured by the base station; and feeding CSI information back to the base station based on a measurement result.
