Hi Juseong,
Thank you for your contribution.
I have couple questions/comments:
-
The problem you are highlighting is technically not P-EDCA specific. As you mentioned, TXOP responder may have an advantage over other devices , but that is the case for
all WiFi devices. May be it make sense to evaluate whether this is a problem at all, how severe it is and if does introduce unfairness – try and solve this in the baseline, so it will be solved for P-EDCA as well.
-
The approach to ignore intra BSS NAV seem problematic to me. How STA that need to send DS determine if the NAV set is just a reminder of protection from previous TXOP or
it is still being used?
-
You SP “11bn shall consider DS-CTS transmission synchronization between multiple STAs for fairness” is very broad and do not have direct connection with the contribution.
“Shall consider DS-CTS transmission synchronization” may have multiple meanings, from “we need PHY level sync to TX DS from multiple STAs” to “NAV synchronization is required between STAs”

Hi all,
I planned to run the SP of the submission during this F2F meeting. Before running the SP, I would like to know your opinion on the submission.
If you have any opinion, please feel free to let me know. Thank you.
