1. A method for transmitting data from an access point in a multiple user multiple input multiple output (MU-MIMO) system, the method comprising:

  • receiving a first indication of signal quality (ISQ) from a first station;

    receiving a second ISQ from a second station;

    setting a first power level and a first modulation and coding scheme (MCS) for transmission of a first aggregated media access control (MAC) protocol data unit (A-MPDU) to the first station as a function of the first ISQ and an amount of payload data corresponding to the first A-MPDU;

    setting a second power level and a second MCS for transmission of a second A-MPDU as a function of the second ISQ and an amount of payload data corresponding to the second A-MPDU;

    transmitting the first A-MPDU at the first power level and within a first frame to the first station; and

    transmitting the second A-MPDU at the second power level and within the first frame to the second station.
