Dear all, I present document 11-20/432r1 early this month, try to fixed the issue when Ack polity set to BA.
https://mentor.ieee.org/802.11/dcn/20/11-20-0432-01-00be-bug-fix-for-acknowledgement-rule-in-multi-link.pptx During the discussion, Matt and other people through the SP text is not clean. The main reasons I understand are 1) The receive status of BA can not know by the transmitter of BA;
