Abstract
An embodiment of the present invention provides a method of supporting acknowledgement transmissions for Uplink (UL) Multi-user Multiple Input Multiple Output (MU MIMO) in wireless networks, comprising, enabling an AP operable in the wireless network to send back acknowledgements to different wireless stations (STAs) in communication with said AP either sequentially or simultaneously by defining a new block ack (BAs) type for multiple STAs.
