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.
Claims20
A method of supporting acknowledgement transmissions for Uplink (UL) Multi-user Multiple Input Multiple Output (MU MIMO) or UL OFDMA in wireless networks, comprising:
- enabling an access point (AP) operable in said 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.
A mobile station (MS), comprising:
- a transceiver adapted for communication with an access point (AP) in a wireless network, said AP including a transceiver adapted to support acknowledgement transmissions for Uplink (UL) Multi-user Multiple Input Multiple Output (MU MIMO) or UL OFDMA in said wireless network by enabling said AP 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.
A computer readable medium encoded with computer executable instructions, which when accessed, cause a machine to perform operations comprising:
- supporting acknowledgement transmissions for Uplink (UL) Multi-user Multiple Input Multiple Output (MU MIMO) or UL OFDMA in wireless networks by enabling an AP operable in said 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.
An access point (AP), comprising:
- a transceiver adapted for communication with a wireless station (STA) in a wireless network, said transceiver further adapted to support acknowledgement transmissions for Uplink (UL) Multi-user Multiple Input Multiple Output (MU MIMO) or UL OFDMA in said wireless network by enabling said AP to send back acknowledgements to different wireless stations (STAs) in communication with said AP either sequentially or simultaneously by defining a new block ack (BA) type for multiple STAs.
