METHOD AND APPARATUS FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for reporting channel status information (CSI) by a user equipment in a wireless communication system, the method comprising:
- receiving, from a base station, a channel status information-reference signal (CSI-RS) based on CSI-RS configuration information provided from the base station; and
reporting, to the base station, the CSI generated by using the CSI-RS,wherein the CSI-RS configuration information includes a plurality of CSI-RS configurations for a first domain antenna group of a 2-dimensional antenna structure of the base station.

Abstract
The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for reporting channel status information. A method for reporting the channel status information (CSI) from a user equipment in the wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving from a base station a channel status information-reference signal (CSI-RS) on the basis of CSI-RS configuration information, which is provided from the base station; and reporting to the base station the CSI that is generated by using the CSI-RS, wherein the CSI-RS configuration information can include a plurality of CSI-RS configurations with respect to a first domain antenna group having a 2-dimensional antenna structure of the base station.
