Initial Process
Coex ad hoc chair created first cut at subgroups for comments (see next slides)
Please review subgroups and provide feedback for modifications to subgroups
We need volunteers for each subgroup
Comment group volunteers review the comments in their respective subgroup
may decide if CIDs do not belong, in which case the CIDs will be moved to another subgroup
Subgroups may be further subdivided and/or reassigned

Rules / Procedure
As a general rule, we will NOT be reviewing CIDs on a one by one basis
Resolution of comments will in most cases be based on submissions
Coex Ad Hoc chair will bring resolutions which passed by 75% or more for motion in TGn, with affirmation of Ad Hoc
Votes between 50% - 75% may be brought to TGn for further discussion and votes to break deadlock

Straw Polls (1/2)
Greenfield transmissions shall be disallowed in channels and regulatory domains where DFS is required until:
1. Acceptable methods of conveying Legacy a OBSS information to all the GF transmitting APs and their associated GF transmitting clients have been approved as IEEE draft text.
2. Acceptable methods of conveying Legacy a OBSS information to GF transmitting clients in an Ad Hoc network have been approved as IEEE draft text.
3. The vendor implementations of these solutions have been proven not to cause radar detection events on legacy a receivers.
