Abstract: Systems and methods are disclosed for scheduling SU and MU traffic in a MIMO communications system. Net goodput may be estimated for a station using a plurality of MIMO modes and a transmission to the station may be scheduled using one of the MIMO modes based, at least in part, on the estimated net goodput. Estimating net goodput may include determining a number of bits that may be successfully transmitted to the station using the MIMO mode divided by a time required to transmit the number of bits plus the sounding time. Further, the number of bits that may be successfully transmitted to the station may be based on the number of packets that may be delivered over the upcoming sounding interval and statistically determined goodput for each MIMO mode.
