METHOD FOR CONFIGURING REFERENCE SIGNAL FOR THREE-DIMENSIONAL MIMO IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
First Claim
1. A method of reporting channel status information (CSI) for multiple input multiple output (MIMO) based beamforming by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving reference signal configuration information including two or more reference signal resources through a higher layer;
receiving CSI process information through the higher layer;
receiving, from a base station, a reference signal based on the reference signal configuration information; and
reporting, to the base station, the CSI calculated based on the CSI process information and the received reference signal,wherein the CSI process information includes a reference signal type indicator indicating a mapping relation between the reference signal configuration information and multiple antennas.

Abstract
In the present application, a method for reporting channel status information (CSI) for multi-antenna-based beamforming by a terminal in a wireless communication system is disclosed. Specifically, the method comprises the steps of: receiving reference signal configuration information including two or more reference signal resources through an upper layer; receiving CSI process information through the upper layer; receiving a reference signal from a base station on the basis of the reference signal configuration information; and calculating the CSI on the basis of the CSI process information and the received reference signal and reporting the CSI to the base station, wherein the CSI process information includes a reference signal type indicator indicating a mapping relationship between the reference signal configuration information and multiple antennas.
