Abstract
The present invention relates to a method and an apparatus for reporting channel status information (CSI). According to one embodiment of the present invention, the method comprises receiving a first CSI-reference signal (CSI-RS) based on CSI-RS configuration information with respect to a first domain antenna group of a two-dimensional antenna structure; reporting a first piece of CSI with respect to the first domain antenna group, which is generated using the first CSI-RS; receiving a second CSI-RS, based on CSI-RS configuration information with respect to a second domain antenna group of the two-dimensional antenna structure; and reporting a second piece of CSI with respect to the second domain antenna group, which is generated using the second CSI-RS, wherein the CSI-RS configuration information with respect to the second domain antenna group can be determined based on the first piece of CSI.
