Hi Qingwei,
Thank you for your quetsion.
I assume that the sequential Ack may be disabled when the coordinating AP doesn't need to control medium of the coordinated AP. For example, even when BAs are sent at the same time, collision may not be occured since BA is basically set to low MCS (I think
this is a rare case.)
Best Regards,
Kosuke (SONY)

Hi Kosuke,
For the SP2, I still have one question. If the bit in the Trigger frame indicate sequential Ack disabled, how the sharing (coordinating) AP control the medium. It means the sharing AP ends the TXOP after transmitting the DL PPDU(Data PPDU)?

Hi Alfred,
Regarding my deffered SP, I had a lot of offline discussions and want to run the following two parts. Could you please add them to the JOINT agenda?
SP1 Do you support adding the following to the SFD? ・ A Co-BF coordinating AP and a Co-BF coordinated AP may use a sequential Ack procedure to avoid Ack collision. ・ In the sequential Ack procedure, the Co-BF coordinating AP and the Co-BF coordinated AP shall set the Ack policy Indicator subfield of the QoS Control field in the Co-BF DL PPDU to "Block Ack". ・ Note: This applies to the Co-SR as well. [Supporting doc: 24/2060]
SP2 Do you support adding the following to the SFD? ・ A Co-BF coordinating AP may enable the sequential Ack procedure by the 1bit indication in the Co-BF Trigger frame. ・ Note: This applies to the Co-SR as well. [Supporting doc: 24/2060]
Best Regards, Kosuke (SONY)
