Hi, all: Based on feedback we collected, we prepared a second version of SP1 and hope to get some early feedback of the WG’s preference: ---------------- Version 1 (current one): - Do you agree to add to the TGbe SFD (in R1), a mode where an AP may announce restricted TWT session(s) such that:
- Any STA supporting this mode, and associated to the AP, shall end its TXOP before the start of the restricted SP(s)
- Note-1: the “restricted TWT” name is TBD.
- Note-2: such restricted TWT SPs are intended to provide more predictable latency performance for latency sensitive traffic.
Version 2 (new): - Do you agree to add to the TGbe SFD (in R1), a mode where an AP may announce restricted TWT session(s) such that:
- Any EHT STA associated to the AP, shall end its TXOP before the start of the restricted SP(s)
- Note-1: the “restricted TWT” name is TBD.
- Note-2: such restricted TWT SPs are intended to provide more predictable latency performance for latency sensitive traffic.
Discussion: - Version-2 focuses on solving the EHT STA problem, and avoid creating “legacy EHT STAs”
- AP may enter this mode at its configuration. For example, it selectively announces this mode in some link(s), e.g. a 6GHz link.
- For legacy STAs, if there is interest in supporting this mode, e.g. joining such TWT sessions, we can discuss further in next step.
- AP can decide if to admit a STA to the BSS or link where the mode is on as one way to handle/mitigate the legacy STA issue. Can discuss this further in next step.
---------------- Feel free to send me or any co-authors an email or reply to this thread. Thank you very much! Chunyu
