Abstract
A method is provided for transmitting channel quality information (CQI) in a MIMO system. A method for allowing a receiver to feed back a CQI value to a transmitter in a Multiple Input Multiple Output (MIMO) system includes receiving a transmission (Tx) pilot signal for each Tx antenna from a base station (BS) measuring a first CQI value of a first codeword and a second CQI value of a second codeword on the basis of the pilot signal and transmitting the first CQI value of the first codeword and the second CQI value of the second codeword to the base station (BS) wherein at least one of the first and second CQI values includes specific information capable of indicating a transmission restriction status of a corresponding codeword.
