Abstract
A method for reporting a channel state of a terminal performed by the terminal is disclosed. The method includes receiving a channel state information-reference signal (CSI-RS) configuration for verifying validity of channel estimation using only a part of two-dimensional (2D) array antenna ports configured for the terminal, verifying the validity of the channel estimation using CSI-RS configuration and obtaining a channel estimation validity indicator, and transmitting the channel estimation validity indicator and channel state information based on the channel estimation validity indicator.
