METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME TECHNICAL FIELD

摘要

The present invention relates to a wireless communication system. In particular, the present invention provides a method and apparatus for reporting channel state information, comprising: measuring a downlink signal from a plurality of base stations; Feedback the first channel state information for a first base station on a subband basis, the first channel state information including identification information indicating a corresponding subband; And the second channel state information for the second base station on a subband basis, wherein a subband corresponding to the second channel state information is set equal to a subband corresponding to the first channel state information, And the two-channel state information does not include identification information indicating the corresponding subband.
