Publication number: 20250016820Abstract: Systems, methods, and mechanisms for preemption of non-low latency data within an aggregated medium access control (MAC) protocol data unit (AMPDU), e.g., such as in current and future IEEE 802.11 systems. A wireless device (e.g., an access point or wireless station) may transmit, during an AMPDU, a trigger to receive (TRX) frame. The TRX frame may indicate preemption of non-low latency data intended for a first wireless station with low latency data intended for a second wireless station, e.g., via an acknowledgement policy change. Additionally, the wireless device may be configured to transmit, to the second wireless station, the low latency data within the AMPDU. Further, the wireless device may be configured to receive, after the AMPDU transmission is complete, a multi-block acknowledgement (M-BA) frame from the second wireless station. The M-BA frame and completion of the AMPDU transmission are separated by a short inter-frame space (SIFS).Type: ApplicationFiled: July 3, 2024Publication date: January 9, 2025Inventors: Zhou Lan, Chittabrata Ghosh, Anuj Batra, Wook Bong Lee, Mohamed Abouelseoud, Morteza Mehrnoush
