摘要：
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 γeff values corresponding to a set of modulation and coding scheme candidates, where γeff is an effective SNR that would yield a same FER in an AWGN channel. The transmitter utilizes the set of γeff values to aid in determining a modulation and coding scheme, and determine a single modulation and coding scheme for all subcarriers within the channel.
