Abstract: A method for providing a low-feedback scheme for link-quality reporting based on the EESM technique is provided herein. During operation, a node will analyze the current channel conditions and determine a non-linear approximation of the carrier to interference plus noise ratio (CINR). The non-linear approximation is sent to a communication unit as a channel-selectivity report, causing the communication unit to utilize the report to assist with modulation and coding selection.

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 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.
