Scheme for configuring reference signal and communicating channel state information in a wireless communication system using multiple antenna ports

摘要

A method for transmitting a channel state information reference signal (CSI-RS) by using multiple antenna ports and receiving CSI in a wireless communication system is provided. The method includes transmitting at least one CSI-RS configuration information for configuring a resource for transmission of the CSI-RS, transmitting the CSI-RS in a resource determined based on the CSI-RS configuration information, and receiving CSI corresponding to the transmitted CSI-RS, in which the CSI-RS configuration information includes information indicating a frequency comb type in which the CSI-RS is transmitted.
