Abstract:
According to one embodiment, a method for receiving a Channel State Information-Reference Signal (CSI-RS) for measuring a channel includes: receiving CSI-RSs on resource elements (REs) in a subframe configured for the CSI-RSs from a base station, wherein if each CSI-RS of the received CSI-RSs is transmitted from each of four or more transmit antenna ports of the base station, at least two REs on which each CSI-RS is received are associated with each of the four or more transmit antenna ports; and transmitting channel state information based on the received CSI-RSs.
