METHOD AND DEVICE FOR APERIODICALLY REPORTING CHANNEL STATE INFORMATION IN WIRELESS CONNECTION SYSTEM

摘要

The present invention relates to methods and devices for aperiodically reporting channel state information (CSI). According to an embodiment of the present invention, a method for aperiodically reporting channel state information may comprise: a terminal receiving an upper layer signal from a base station, the upper layer signal containing information about at least one allocated CSI measurement group; the terminal receiving a physical downlink control channel (PDCCH) signal via a first subframe from the base station, the PDCCH signal containing a CSI request field; the terminal setting a second subframe as a CSI reference resource based on the first subframe; and determining whether at least one CSI measurement group to which a CSI reference resource is allocated is included.
