METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION FOR SUPPORTING 256 QAM IN WIRELESS ACCESS SYSTEM
First Claim
1. A method for transmitting a Channel Quality Indication (CQI) index by a User Equipment (UE) capable of supporting 256-ary Quadrature Amplitude Modulation (256QAM) in a wireless access system, the method comprising:
- measuring channel quality for one or more Channel State Information (CSI) subframe sets configured for the UE; and
transmitting a CQI index corresponding to the channel quality measured for each of the one or more CSI subframe sets according to a first CQI table or a second CQI table,wherein the first CQI table is capable of supporting up to 64QAM, the second CQI table is capable of supporting up to 256QAM, and the first CQI table or the second CQI table is configured for each of the one or more CSI subframe sets.

Abstract
The present invention relates to a wireless access system, and to methods for transmitting and receiving channel state information (CSI) for supporting a 256 quadrature amplitude modulation (QAM) modulation mode, and devices for supporting the same. The method by which a terminal transmits a channel quality indication (CQI) index for 256 QAM in a wireless access system, according to one embodiment of the present invention, can comprise the steps of: measuring channel quality for one or more CSI subframe aggregation; and transmitting a CQI index for the channel quality respectively measured for the one or more CSI subframe aggregation according to a first CQI table or a second CQI table. In this situation, the first CQI table is capable of supporting up to 64QAM and the second CQI table is capable of supporting up to 256QAM, and the first CQI table or the second CQI table is capable of being respectively set relative to the one or more CSI subframe aggregation.
