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

  • in a multiple-input-multiple-output (MIMO) communication system utilizing a plurality of modulation types and a plurality of spatial streams,determining an aggregate noise characteristic based upon a noise characteristic of each of said plurality of spatial streams; and

    configuring a receiver to receive subsequent data based on one or both of;

    a current modulation type for modulating a current spatial stream and at least one subsequent modulation type for modulating at least one subsequent spatial stream,wherein said current modulation type and said at least one subsequent modulation type are based on said determined aggregate noise characteristic.
