IEEE P802.15 Working Group Submission: A Map of 4ab Enhancements
This submission provides a graphic overview of proposed enhancements for the IEEE 802.15.4ab standard, emphasizing interrelationships to facilitate convergence and reduce implementation burden. Key elements include HPRF mode data enhancements, wake-up radio features, data rates, coding schemes, and channel access improvements. Recommendations for convergence before text generation are highlighted to streamline the drafting process and enhance interworking efficiency.

June 2022 doc.: <15-22-0316-01-04ab> Introduction This submission presents a graphic overview of the various items proposed to TG4ab for inclusion into the IEEE 802.15.4ab amendment. This is presented as a single page map showing how these items are interrelated and overlapping. The hope is that seeing these relationships will facilitate the group to converge more smoothly as the various parties understand the relationships between the items. Where there are overlaps it is preferrable to converge to a common solution rather than have multiple separate options that increase implementation burden. Billy Verso, (Qorvo) Submission Slide 2

June 2022 doc.: <15-22-0316-01-04ab> Conclusion This submission presented a single page graphic overview of the elements TG4ab is considering for the standard and shows how these are interrelated. To reduce the drafting workload, the author recommends that the group progresses convergence of the various proposals before text generation. Converging / merging proposals as much as possible to limit the number of options will help interworking and reduce the implementation / testing burden. Billy Verso, (Qorvo) Submission Slide 4
