Abstract: A method for selecting members of a client uplink group is described. An uplink traffic characteristic information signal is received from each of a plurality of communication devices. Multiple communication devices of the plurality of communication devices are selected as members of a client uplink group based at least on traffic information indicated by the respective uplink traffic characteristic information signals. An uplink group definition frame is transmitted to each member of the client uplink group. The uplink group definition frame indicates an uplink multi-user multiple input multiple output (MU-MIMO) transmission schedule for the client uplink group for members of the client uplink group to simultaneously transmit to an access point. The members of the client uplink group are triggered to transmit uplink data frames simultaneously.
