Abstract
In a multi-carrier communication system employing adaptive modulation and coding a receiver feeds back channel quality information for a binned group of subcarriers instead of sending an individual quality report for each subcarrier. A transmitter will utilize the channel quality information for the bin to determine a set of Geff values corresponding to a set of modulation and coding scheme candidates where Geff is an effective SNR that would yield a same FER in an AWGN channel. The transmitter utilizes the set of Geff values to aid in determining a modulation and coding scheme and determine a single modulation and coding scheme for all subcarriers within the channel.
