Method for feeding back channel quality indicator in wireless communication system and apparatus therefor
In this application, a method for a terminal reporting to a base station a channel quality indicator (CQI) in a wireless communication system is disclosed. More specifically, the method comprises the steps of: calculating a precoding matrix index and a rank indicator; and selecting and reporting the CQI index from one of a first CQI index table and a second CQI index table under the assumption that the precoding matrix index and the rank indicator are applied, wherein the first CQI index table and the second CQI index table indicate a modulation order and a coding rate indicated by the CQI index, and the second CQI index table supports a higher modulation order than the first CQI index table.
