Patent ID: 8374197

Claim:
A method for link adaptation at a base station using metric feedback, comprising: communicating with a mobile station over a communication link having one or more sub-channels; during the communication, receiving an index transmitted from the mobile station corresponding to a plurality of mutual information per coded bit metrics for a plurality of candidate modulation types per coding layer, wherein the mutual information per coded bit metrics are based on channel state knowledge of the sub-channels, wherein the index is based on a predetermined table known to both the base station and the mobile station, and wherein the predetermined table is defined based on joint probability distribution of the plurality of mutual information per coded bit metrics and coding rate constraints for each candidate modulation type per coding layer; based on the received index, predicting operational performance of the mobile station in view of one or more transmission parameters and one or more performance factors; and selecting one or more of the transmission parameters, including a modulation type selected from one of the plurality of candidate modulation types per coding layer, based on a transmission condition of the communication link.
