Abstract

A method for transmitting a channel status information reference signals (CSI-RSs) for a maximum of eight antenna ports includes mapping the CSI-RSs for a maximum of eight antenna ports onto a data region of a downlink subframe having a normal cyclic prefix (CP) configuration according to a predetermined pattern; and transmitting the downlink subframe to which the CSI-RSs mapped, wherein the predetermined pattern defines the CSI-RSs to be mapped onto two OFDM symbols of the data region in the downlink subframe and mapped to at least one of four subcarrier positions in each of the two OFDM symbols, and wherein the four subcarrier positions defined by the predetermined pattern may be two consecutive subcarrier positions and two other consecutive subcarrier positions spaced apart by four subcarriers.
