<p>The present invention provides a method and an apparatus for transmitting a reference signal in a wireless communications system. According to the present invention, a base station (BS) performs the following procedures: transmitting a channel state information (CSI) reference signal (RS) resource configuration indicator to a mobile station (MS), wherein the CSI-RS resource configuration indicator corresponds to either an exiting CSI-RS configuration set or to an additional CSI-RS configuration set; mapping a generated CSI-RS sequence onto resource elements in a subframe by using a modulation symbol according to a CSI-RS pattern of either the existing CSI-RS configuration set or the additional CIS-RS configuration set selected based on the CSI-RS resource configuration indicator; and transmitting a signal based on the mapped CSI-RS sequence to the MS.</p> |
