Hi Morteza,
Thank you for the explanation. This clarifies my understanding.
Regarding your suggestion, I think adding a note would be helpful.
Do you think something like the following text would be appropriate?
(e.g., right after item 7 in the section "If a DSO AP and a DSO non-AP STA operate in DSO mode, the following apply:" (D1.3, p.305, l.56))
text: "NOTE 3 - If a DSO non-AP STA receives a Trigger frame on the DSO subband and successfully transmits at least one QoS Data frame in a TB PPDU, the DSO non-AP STA updates the MU EDCA Timer in the same manner as on the primary subband, as defined in 26.2.7."
Best Regards.
Yuki Tsujimaru

Hi Yuki,
The behavior of MU EDCA on DSO subband is similar to primary subband, we don't need to have different behavior for DSO, i.e. if DSO STA receives a trigger frame on DSO subband to respond the TB PPDU, it sets the MU EDCA Timer similar to primary.
I am not sure why the channel switch would reset the timer.
The comment is not clear that it is asking for this; if this helps we can add a note for clarification.
Thanks,
Morteza

Hi Morteza,
Thank you for your contribution 25/2359.
I am writing to ask for clarification regarding CID6022 which was deferred during the January interim.
Although EDCA is not performed during a DSO sequence, the MU EDCA Timer can still be set by a Trigger-Based uplink transmission.
As my understanding, there are no rules to prevent setting the MU EDCA Timer on the DSO subband.
So would you please clarify whether the MU EDCA Timer is also set by a TB PPDU transmission even during a DSO sequence?
If so, what happens to the timer upon switching back to the primary subband?
While a channel switch might reset the timer, it is not explicitly stated whether this applies after returning from a DSO sequence.
I would appreciate your guidance on the expected behavior.
Best Regards,
Yuki Tsujimaru
