1. A method for communicating information in a communication system, the method comprising:

  • performing by one or more circuits and/or processors;

    computing, for each of a generated plurality of spatial stream signals, a corresponding signal to noise ratio for each of a plurality of frequencies;

    computing, for said each of said generated plurality of spatial stream signals, a corresponding geometric mean signal to noise ratio based on said computed plurality of corresponding signal to noise ratios;

    selecting a corresponding modulation type identifier, for said each of said generated plurality of spatial stream signals, based on said computed corresponding geometric mean signal to noise ratio; and

    communicating, via one or more uplink RF channels, feedback information comprising one or both of said selected plurality of corresponding modulation type identifiers and said computed plurality of corresponding geometric mean signal to noise ratios.
