Abstract:
A method and apparatus for transmitting and receiving channel status information (CSI) for supporting 256QAM in a wireless access system are disclosed. A method for transmitting a Channel Quality Indication (CQI) index for 256QAM (Quadrature Amplitude Modulation) in a wireless access system includes: receiving, by a user equipment (UE), a message including a 256QAM indicator indicating use of a 256QAM scheme; performing channel measurement of a downlink channel through which downlink data is transmitted; and transmitting a CQI index in response to the channel measurement result to a base station (BS), wherein the UE simultaneously manages a first CQI feedback table for supporting a legacy modulation scheme and a second CQI feedback table for supporting the 256QAM scheme.
