Multiuser block acknowledgment request

Abstract:

Disclosed herein are system, method, and computer program product embodiments for performing multiuser block acknowledgement in a wireless communication protocol. Embodiments include receiving a control frame from an access point (AP). A transmission mode can be determined based on a trigger information field in the control frame. Further, a data frame to acknowledge can be determined based on a block acknowledgement request (BAR) field in the control frame. A block acknowledgment (BA) frame can be generated based on the data frame to acknowledge. The BA frame can then be transmitted to the AP based on the transmission mode, e.g., at the same time another BA frame is transmitted to the AP by another station.
