MU-MIMO Ad-hoc Operating Rules (1) According to 11/09-0059r4*: 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. *11-09/0059r4 = 802.11ac Proposed Selection Procedure

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 Email via TGac reflector 75% affirmative vote rquired for progress

Scope of work Discussion topics from 11-09/1175r1* Downlink MU-MIMO Uplink MU-MIMO MU-MIMO parameters (e.g. # of streams, # of clients) Training protocols ACK protocols Reservation/polling protocols *11-09/1175r1 = Proposed Scope of TGac Ad Hoc Groups

Ad-hoc Life cycle Life cycle from 11-09/1181r1* Establishing requirements Making top-level design decisions Writing draft text Resolving comments Output to spec framework Output to draft amendment *11-09/1181r1 = TGac Ad-hoc lifecycle model
