Hi all,
Based on the feedback, it seems there is strong preference not to make major changes to the CTDMA design. As such, would reject CID 6628, 10376.
Regarding CIDs that are asking for fairness rules for CBF, CSR (e.g., 10187), if we compare with the rules we have for CTDMA, then CBF/CSR automatically satisfy the 33% proportional constraint on allocated time since the PPDUs transmitted by the two APs are aligned in time. We could add the other part of CTDMA constraint that limits maximum allocated duration to min (VI TXOP limit, TXOP limit of the primary AC used to obtain that TXOP by sharing AP) if there is interest. Please let me know your thoughts.
Regards,
Dibakar

Subject: 11bn LB291 CR request: 11-25-1934 -CR for MAPC fairness
Hello Dibakar,
I would like to provide a feedback on 11-25-1934 -CR for MAPC fairness, specifically on
- comment 6125:
- a minor editorial suggestion, please consider using “just above” or “as described directly above”
- comments 6628 and 10376 :
- we have already a general rule in 11bn for coordinated AP(s) (i..e, AC_{shared_AP} >= primary AC)
that is flexible for coordinated AP(s) to follow without violating EDCA requirements for the gained TXOP by coordinated APs.
Why to revisit now (when we already have 1.0draft) the basic C-TDMA framework what members have discussed intensively at early stages of C-TDMA development and agreed upon in the past ?
C-TDMA is intended for LL traffic, and coordinated APs will prioritize AC VO/VI to serve during the shared portion of TXOP.
Ironically, the section on fairness (Section 37.27) on which members spent a good amount of time was discussed/developed to support the current model (without additional rules/and constraints on coordinated APs).
Thank you,
