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 From: *** 802.11 TGax - HEW - High Efficiency WLAN *** [mailto:STDS-802-11-TGAX@xxxxxxxx]
