Abstract
The present invention provides various methods for transmitting a channel state information reference signal (CSI-RS) by varying a transmission period for each antenna port or antenna port group, and also provides apparatuses supporting the methods. The method for receiving a CSI-RS in a wireless access system according to one aspect of the present invention may comprise the steps of: receiving a CSI-RS component information element for setting CSI-RS transmission periods for two or more antenna ports to be mutually different; receiving CSI-RSs for each of the two or more antenna ports based on the CSI-RS component information element; and acquiring channel state information for each of the two or more antenna ports based on the received CSI-RS.
