ABSTRACT:
For use with a multiple-input, multiple-output (MIMO) transmitter, a signal field controller, a method of controlling signal fields and a MIMO transmitter incorporating the controller or the method. In one embodiment, the controller includes: (1) a primary signal field mode indicator configured to cause a primary signal field to indicate a presence of a supplemental signal field and provide the primary signal field to the MIMO transmitter for transmission thereby and (2) a supplemental signal field generator coupled to the primary signal field mode indicator and configured to provide a supplemental signal field to the MIMO transmitter for further transmission thereby only when the primary signal field indicates the presence.
