9814 Young Hoon Kwon 37.23 Not clear what "the format defined below" means here. It's better to have figure that describes the format for Multi-STA BlockAck, instead. Or, it can also refer to Figure 9-32. Per comment. Revised – Will to figure TGax editor shall incorporate changes in 9815 Young Hoon Kwon 37.24 Normative descript is not appropriate in clause 9. Delete the sentence BlockAck frames shall be supported if either UL MU or A-MPDU operation is supported.", and describe the normative behavior in Clause 10 or Clause 27.

And, the sentence is somewhat misleading as there's no acknowledgement contained in the Per AID TID Info subfield.

Revised – Revised to make the text under NOTE in the main body text. TGax editor incorporate changes in 9817 Young Hoon Kwon 38.04 Does the TID value set to 15 imply a management frame or an action frame?
