METHOD FOR CONFIGURING REFERENCE RESOURCE OF CHANNEL STATUS INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

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.

主权项

1. A method of reporting CSI (channel status information) on a FDD (frequency division duplex) secondary cell, which is reported by a user equipment in a wireless communication system to which a carrier aggregation technique is applied, comprising the steps of:
configuring subframes of the FDD secondary cell, which are matched with a position of downlink subframes of a specific uplink/downlink subframe configuration of a TDD (time division duplex) primary cell or a position of special subframes containing a downlink resource longer than a predetermined length, as valid subframes for measuring the CSI; measuring the CSI from at least one of the valid subframes; and reporting the CSI to a network.
