1. A method implemented in a multiple-input, multiple-output (MIMO) wireless communication system, comprising:

  • transmitting each of a plurality of data streams from a first station to a second station in a permuted fashion over a plurality of MIMO channels;

    inversely permuting the data streams at the second station;

    determining a quality metric for each of the data streams at the second station;

    determining a condensed quality metric at the second station based on the quality metrics for each of the data streams; and

    transmitting the condensed quality metric from the second station to the first station.
