Method for reporting aperiodic channel information in multi cell-based wireless communication system and device therefor

摘要

The present application discloses a method for enabling a terminal to report channel status information in a base station cooperative wireless communication system. Particularly, the method for enabling a terminal to report channel status information in a base station cooperative wireless communication system comprises the steps of: receiving, from a serving base station, first resource setting information for a channel status information-reference signal (CSI-RS) and second resource setting information for measuring interference: receiving a triggering signal for reporting the channel status information from the serving base station; calculating the channel status information on the serving base station and/or one or more cooperative base stations by using the first resource setting information and the second resource setting information; and reporting the channel status information to the serving base station, wherein the first resource setting information and the second resource setting information include information on an antenna port capable of referring to a large scale property of a wireless channel.
