Method and System for Link Adaptation Using Metric Feedback

A method for link adaptation at a mobile station, comprising:

• computing a plurality of mutual information per coded bit metrics for a plurality of candidate modulation types per coding layer based on a channel state knowledge of one or more sub-channels;
• generating feedback information, wherein the feedback information includes the plurality of mutual information per coded bit metrics for the plurality of candidate modulation types per coding layer according to a request from a base station with which the mobile station is communicating;
• and
• transmitting the generated feedback information to the base station.

A mobile station for link adaptation using metrics, comprising:

• a transceiver for communicating with a base station;
• and
• a processor coupled to the transceiver, wherein the processor:
• computes a plurality of mutual information per coded bit metrics for a plurality of candidate modulation types per coding layer based on a channel state knowledge of one or more sub-channels;
• and
• generates feedback information, wherein the feedback information includes the plurality of mutual information per coded bit metrics for the candidate modulation types per coding layer according to a request from the base station,
• wherein the transceiver transmits the generated feedback information to the base station.
