| Hello Patrice, Thank you for your comments.
In CID8293 resolution I am trying to follow the 802.11 operating principles for reverse direction protocol and EDCA. The reverse direction protocol may be used both the legacy STA and HE STA and in both cases the RD responder does not update the backoff. Similarly as in HCCA, the RD may allow transmission of frames from any AC. Again, regardless of the AC where the frames were transmitted, the responder does not reset its backoff to any AC from which it has received an MPDU. I find it unfair to make different rules for 802.11ax and legacy STAs.
802.11ax is not capable to change the backoff handling of the legacy STAs, it can only define how 802.11ax devices operate. To me it sounds that you would like to change the general mechanism when the backoff is reset. The best group to make the change for all STAs and to ensure the fairness among all STAs is the maintenance group.
If you like, we can continue off-line discussions on the topic.
Best regards, Jarkko Kneckt
Hello Jarkko and all, Thanks for your comment resolution. I would like to come back about the CID8293 resolution. You rejected the comment because the RD mechanism never defined the update of the backoff except for the primary AC. I agree with you. But now , the RD mechanism in 802.11ax is enhanced and stronger because the RD responder is able to transmit any data packets from the primary AC and the higher ACs. So I think that the QoS management (introduced and approved in 802.11e for a long time) is now completely broken. This is the same way for the MU UL mechanism. With all these new medium access mechanisms introduced by 802.11ax , 802.11e features are bypassed. STA cannot ensure QoS because the QoS data transmission is not based on the backoff mechanism anymore. The HE STA behavior is not fair with legacy STA. Reset the current backoff of the transmitting ACs allows not only to ensure the fairness with legacy STAs but also to synchronize the backoff value with the AC FIFO. If an AC FIFO is empty after a RD execution, no dedicated backoff has to be decreased. Patrice Hello, thank you for the opportunity to present the submission 17-191r2 today at 802.11ax teleconference. The new revision contains the live edits done in the teleconference and it answers to comments received in the teleconference. Your comments and suggestions are welcome. _______________________________________________________________________________ If you wish to be removed from this reflector, do not send your request to this reflector - it will have no effect.
