METHOD AND APPARATUS FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system and, more specifically, to a method and apparatus for reporting channel state information (CSI). According to one embodiment of the present invention, the method by which a terminal of the wireless communication system reports the CSI comprises: a step of receiving a reference signal from a base station; and reporting the CSI generated using the reference signal to the base station. The CSI can include a report type indicator(RTI) for indicating whether a second domain pre-coding matrix indicator (PMI) indicating a second pre-coding matrix for a second domain is reported in a two-dimensional antenna structure defined by a first domain and the second domain is reported.
