1. A wireless network device comprising:

  • R modulation modules configured to (i) receive R independent data streams, (ii) modulate the R independent data streams, and (iii) apply a multiplexing matrix to generate M modulated and multiplexed data streams, respectively, where R and M are integers greater than one;

    M summing modules configured to sum portions of each of the M modulated and multiplexed data streams to generate M transmit data streams;

    M transmitters configured to simultaneously transmit the M transmit data streams during a simultaneous downlink transmission period to R client stations; and

    M receivers configured to respectively receive R acknowledgements from the R client stations during R allocated time slots of the simultaneous downlink transmission period.
