Insights on Future Wireless Standards Development
Delve into the progression of IEEE 802.11 standards with a focus on the transition from 802.11be to the next generation. Discussions revolve around the evolution of PHY/MAC task groups, motivations for the new generation, and potential enhancements in system efficiency, latency, throughput, and spectral utilization. The proposal suggests redefining the scope of 802.11be Release 2 and shifting Multi-AP features to the upcoming iteration for further advancements in wireless technologies.

January 2022 doc.: IEEE 802.11-22/0032r0 Thoughts on Next Generation After 802.11be Date: 2022-01-DD Authors: Name Vinko Erceg Affiliations Broadcom Address Phone email vinko.erceg@broadcom.com Submission Slide 1 Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Abstract Thoughts on Next Generation PHY/MAC Task Group Submission Slide 2 Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Introduction Release 1 802.11be is in the completion stage, comment resolution is well on the way There were some thoughts presented regarding Release 2 of 802.11be https://mentor.ieee.org/802.11/dcn/21/11-21-1598-01-00be-discussion-on-r2.pptx Conclusion of this presentation was to keep 11be R2 scope small, to move Multi-AP features from R2 to next generation (different alphabet) In this presentation we elaborate on the above thoughts regarding 802.11be R2 and propose formation of the new next generation PHY/MAC Task Group Submission Slide 3 Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Need for Next Generation PHY/MAC Task Group Historically, there was 4-5 year cadence in formation of new PHY/MAC Task Groups Driven by technological demand and product cycles, requirements such as: Device throughput Overall system throughput Efficiency Latency Reliability Power consumption Etc. Submission Slide 4 Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Some Examples That May Drive Next Generation Emerging Requirements Cloud AR/VR/MR Very low latency and high throughput Video - 8K, 16K Edge computing Sensory inputs Automation 6GHz spectrum utilization Other reasons: Just for the sake to have better, faster, with less power consumption and more reliable for the new release cycles of devices (phones, tablets, IoT devices, etc.) Submission Slide 5 Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Possible 802.11be R2 Outcome As mentioned earlier, seems there is a push for making 802.11be R2 slim Multi-AP to be moved to the next generation Above can be taken further to make 802.11be R2 less PHY centric Possibility of MAC/Protocol only 11be R2 PHY features that were discussed in 11be can be reconsidered in the next generation Task Group Discuss additional features that enhance, for example: Throughput (>2x 11be) Latency (< 1 ms, possibly < 0.1 ms) System efficiency Power consumption Better 6GHz spectrum usage Slide 6 Submission Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Next Generation Timeline 802.11be timeline: Study group was created in July 2018 D1.0 in May 2021 Industry interop end of 2023 Potential next generation task group timeline that follows 802.11be timeline: Study group in July 2022 D1.0 in May 2025 Industry interop end of 2027 Submission Slide 7 Vinko Erceg, Broadcom
January 2022 doc.: IEEE 802.11-22/0032r0 Proposal Discuss next in WNG need/drivers/requirements for the next generation PHY/MAC program Start next generation program Study Group in July 2022 Formation per IEEE 802.11 guidelines to meet the above date Submission Slide 8 Vinko Erceg, Broadcom
