Abstract:
A method for transmitting control information to request a Channel Quality Indicator (CQI) in a wireless communication system supporting a plurality of transmission bands is disclosed. The method includes generating control information including downlink transmission band indication information and CQI request information, the downlink transmission band indication information indicating a downlink transmission band requiring CQI reporting among a plurality of downlink transmission bands and the CQI request information requesting CQI reporting for the downlink transmission band, and transmitting the generated control information on a downlink control channel of a predetermined downlink transmission band among the plurality of downlink transmission bands.
