8. Ganesh Venkatesan (Intel) presented “GCR using SYNRA for GLK”, 11-15/150r3

9. Ganesh Venkatesan (Intel) presented “An adaptation of GCR for GLK links”, 11-15/283r1
1. Q: Shouldn’t the GLK Capabilities Element be “Extensible”? A: This is a bit-map so they will be no future sub-elements added to it to provide additional-information.
2. C: There are actually two types of extensibility for elements: one just indicates that it can be longer and anything after the part you understand can be ignored (Extensible column of Element IDs table = “Yes”), the other indicates that if it is longer that additional space is filled in with subelements (Extensible column of Element IDs table = “Subelements”). This element should be extensible in the first of those two ways.
3. C: In the GLK-GCR Parameters Field format, we do not need to indicate the A-MSDU support, since a GLK STA that support GCR will also support A-MSDU?
