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

摘要

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.

1. A method for reporting channel status information (CSI) from a user equipment in a wireless communication system, the method comprising:
receiving from a base station a first channel status information-reference signal (CSI-RS) based on CSI-RS configuration information for a first domain antenna group of a two-dimensional antenna structure, the CSI-RS configuration information for the first domain antenna group being provided from the base station; reporting to the base station first CSI for the first domain antenna group, the first CSI being generated by using the first CSI-RS; receiving from the base station a second CSI-RS based on CSI-RS configuration information for a second domain antenna group of the two-dimensional antenna structure, the CSI-RS configuration information for the second domain antenna group being provided from the base station; and reporting to the base station second CSI for the second domain antenna group, the second CSI is generated by using the second CSI-RS, wherein the CSI-RS configuration information for the second domain antenna group is determined based on the first CSI.
