US 2017/0012756 A1 · 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.

Dependent claims

A method for performing block acknowledgement, comprising:

receiving, by at least one processor, a control frame from an access point (AP), wherein the control frame includes a trigger information field and a block acknowledgement request (BAR) field;
determining, by the at least one processor, a transmission mode based at least in part on the trigger information field;
determining, by the at least one processor, a data frame to acknowledge based at least in part on the BAR field;
generating, by the at least one processor, a block acknowledgment (BA) frame based at least in part on the determined data frame to acknowledge;
and
transmitting the BA frame to the AP based at least in part on the determined transmission mode, wherein the BA frame is transmitted at a time when at least one other station is scheduled to transmit a different BA frame.
