Title:
METHOD FOR CHANNEL STATE REPORT USING APERIODIC CHANNEL STATE INFORMATION-REFERENCE SIGNAL AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/204546
Kind Code:
A1
Abstract:
Provided is a method for channel state report using an aperiodic channel state information-reference signal (CSI-RS) in a wireless communication system according to an embodiment of the present invention, the method performed by a terminal and comprising the steps of: receiving a plurality of aperiodic CSI-RS resource settings contained in a single CSI process; receiving an indicator which indicates an aperiodic CSI-RS according to one of a plurality of aperiodic CSI-RS resource settings; and calculating channel state information on the basis of the aperiodic CSI-RS indicated by the indicator when receiving a CSI request using an effective aperiodic CSI-RS and reporting the same to a base station, wherein the plurality of aperiodic CSI-RS resource settings may comprise parameters which are commonly applied to a plurality of CSI-RS resource settings in the single CSI process.
