Title:
METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/031879
Kind Code:
A1
Abstract:
The present specification provides a transmission and reception method for reporting channel state information (CSI) in a wireless communication system, and an apparatus therefor. Particularly, the method for reporting the CSI in the wireless communication system comprises the steps of: receiving, from a base station, configuration information for control channel-based CSI reporting; receiving, from the base station, downlink control information including information for indicating a CSI reporting time at which the control channel-based CSI reporting is performed; and reporting the CSI, which is measured by a CSI-reference signal (CSI-RS) received from the base station, through the control channel at the CSI reporting time, wherein the configuration information can include information for indicating one or more control channel resources allocated for the control channel-based CSI reporting.
