METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION

摘要

The present invention relates to a method in which a terminal transmits channel status information in a multi-carrier system, and to a terminal which uses the method. The method comprises the following steps: receiving a reference signal from a base station; transmitting first channel information to the base station; and transmitting second channel information to the base station, wherein the first channel information includes information for indicating one or more precoding matrices estimated using the reference signal, and the second channel information includes any one precoding matrix from among one or more precoding matrices indicated by the first channel information.
