The present invention relates generally to wireless networking, and more particularly to methods and apparatuses for increasing throughput of wireless devices and systems in a wireless network. The invention includes transmitting one or more signaling frames from one wireless device in the wireless network to other wireless devices (STAs) in the wireless network. The one or more signaling frames contain information concerning channel allocation for the transmission and requirement for the acknowledgement frames between the transmitting wireless device and the receiving wireless devices. This invention allows wireless devices not allocated the transmission medium to sleep during a transmission burst and different wireless devices allocated the transmission medium to be scheduled in different data transmission bursts.
