Method for configuring reference resource of channel state information in wireless communication system and apparatus therefor
Disclosed is a method for reporting, by a terminal, channel status information (CSI) on a frequency division duplex (FDD) secondary cell in a wireless communication system to which a carrier aggregation technique is applied. Specifically, the method comprises the steps of: configuring, as valid sub-frames for measuring the CSI, sub-frames in the FDD secondary cell which coincide with the position of downlink sub-frames or the position of special sub-frames including a downlink resource of a predetermined length or more on a specific uplink/downlink sub-frame configuration of a time division duplex (TDD) primary cell; measuring the CSO in at least one of the valid sub-frames; and reporting the CSI to a network.
