Scope of work
Ad-hoc lifecycle
Long term agenda

3. MU-MIMO Ad-hoc chairs Brian Hart Sameer Vermani Robert Stacey
Chairs will rotate. Take turns in running the meetings.
Primary responsibility is to ensure that work progresses in the ad-hoc

4. MU-MIMO Ad-hoc Operating Rules (1)
According to 11/ r4*:
Ad Hoc Groups can establish their own decision-making rules as appropriate for the task (Decision by 2/3 majority of Ad Hoc group participants recommended)
In the case a consensus can not be reached within an Ad Hoc group (a stalemate that prohibits further progress), the subject will be brought up in front of the Taskgroup where 75% approval rate will be required. A vote of 50% in the Ad Hoc group shall be sufficient to move an issue to the Taskgroup. A vote of 50% in the Taskgroup shall be sufficient to move an issue previously assigned to an Ad Hoc group back to the adhoc group.

5. MU-MIMO Ad-hoc Operating Rules (2)
Attendance will not be recorded
Minutes will be taken (by one of the chairs or a volunteer)
Straw poll results will be recorded
No motions – progress made through straw polls
via TGac reflector
75% affirmative vote rquired for progress

*11-09/1175r1 = Proposed Scope of TGac Ad Hoc Groups

7. Ad-hoc Life cycle Life cycle from 11-09/1181r1*
