Abstract  Abstract

A method implemented in a multiple-input multiple-output (MIMO) wireless communication system is disclosed. The method comprises 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. The transmitting the data streams in a permuted fashion comprises mixing the data streams on the MIMO channels in a pseudorandom pattern that comprises a full permutation of possible combinations of the data streams and the MIMO channels. Also disclosed is a method for multiple-input multiple-output (MIMO) wireless communication. This method comprises encoding each of a plurality of data streams according to corresponding data rates; transmitting the data streams in a permuted fashion over a plurality of MIMO channels from a first station to a second station as described above; receiving a condensed quality metric; and adjusting the data rates at which the data streams are encoded based on the condensed quality metric. Further disclosed is a method for multiple-input multiple-output (MIMO) wireless communication. The method comprises receiving a plurality of permuted data streams over a plurality of MIMO channels inversely permuting the data streams; determining a quality metric for each of the data streams; determining a condensed quality metric based on the quality metrics for each of the data streams; and transmitting the condensed quality metric to a base station. The data streams are permuted by mixing the data streams on the MIMO channels in a pseudorandom pattern that comprises a full permutation of possible combinations of the data streams and the MIMO channels. A base station mobile station and the multiple-input multiple-output (MIMO) wireless communication system are also disclosed.
