In a wireless communication system comprising at least one access point (AP) and a plurality of stations (STAs), a method for transmission management of the wireless medium comprises the AP configuring a Multiple Receiver Aggregate Multi-Poll/Power Save Aggregation Descriptor (MMP/PSAD) frame with scheduled Uplink Transmission Time (ULT) information for the plurality of STAs. The AP then transmits the MMP/PSAD frame to the plurality of STAs. Upon successfully receiving and decoding the MMP/ PSAD frame, STAs transmit during their scheduled ULT.
