Hi Ming, Rubayet, Liwen touched on a crucial aspect of MLO: Due to the nature of multi-link operation, an individually addressed Mgmt frame can be transmitted on any available link. This is one of the key reasons why the standard has defined a procedure
for identifying the intended link for an individually addressed Mgmt frame (i.e., the Link ID bitmap in TWT IE or an explicit IE to be carried in a mgmt frame). In other words you won't know up-front, which link a TWT setup frame will get transmitted on. Therefore,
you can't tie it to any particular link's TSF. This problem won't occur with the solution already defined in the spec - i.e., the TWT field in the TWT IE is tied to that one link which is signaled via the Link ID bitmap and therefore is agnostic to which link the setup frame ultimately
gets sent out on. If your goal is to setup synchronized TWTs, you can include a TWT IE for each link (with the corresponding Link ID bit set to 1) and the TWT field set to the value based on the TSF of the intended link.
Before adding more "fixes" to your proposal and making more complicated, we need to ask ourselves: Does the existing solution work under all scenarios? If the answer is yes, then what is the need for an alternative (and more complex) solution? Regards, Abhi From: Yongho Seok <yongho.seok@xxxxxxxxx> WARNING:
This email originated from outside of Qualcomm. Please be wary of any links or attachments, and do not enable macros. I have a similar comment but the solution is different. Current 11be TWT can establish the overlapped TWT SPs on multiple links, and TWT SPs are independent of the transmitting link of the TWT Setup frame. It seems that reusing/extending the existing 11be TWT is better instead of defining another
TWT operation. Thanks, Yongho 2022년 5월 6일 (금)
