Hi Laurent,
I have a few questions:
- Why is necessary to set a default PS state for the link on which the multi-link was setup?
As, the STA link is active during the setup process and “normal” PS state procedures can be used to set the link’s PS state. Also, if we define the setup process as a frame exchange – any change in state of the link signaled during the frame exchange, does
not take effect until the frame exchange is completed – hence the STA can easily set its own “initial” state as it desires. - If the STA is establishing a MLD wouldn’t it do so to use it once it is established? So, why would it be advantageous to establish a MLD and have it be effectively a single link connection,
until the other links are activated? Why require all the additional signaling to turn the links on?
- If a STA only needs a single active link why would it bother setting up multi-links? Wouldn’t it be simpler to just associate via legacy modes and set up a single link and then when
it needs multiple links establish them then?
- Given the overhead of managing a multi-link connection wouldn’t it be more efficient to only use multi-link connections when they are required/desired?
Regards,
Joseph

Hi all,
Q/A were stopped at the end of last 11be MAC call, for the contribution on power save state after enablement.
https://mentor.ieee.org/802.11/dcn/20/11-20-0391-00-00be-multi-link-power-save-state-after-enablement.pptx
I can answer your questions here if there are still remaining ones.
Thanks,
Laurent
