METHOD FOR REPORTING CHANNEL STATUS INFORMATION IN A MULTI ANTENNA WIRELESS COMMUNICATION SYSTEM AND DEVICE FOR SAME |
摘要 |
<p>The present application discloses a method for reporting channel status information in a multi antenna wireless communication system. In more detail, the method includes: receiving a reference signal from a base station; calculating the optimum precoding matrix index (PMI), at which the intensity of a signal from the base station is maximized, on the basis of the reference signal; determining at least one interference PMI from the base station on the assumption that a plurality of interference PMIs corresponding to the optimum PIM are applied; and transmitting information on at least one determined interference PMI to the base station. Beams corresponding to the plurality of interference PMIs are orthogonal to the beams corresponding to the optimum PMI.</p> |
