  3. Review the LB211 comment spreadsheet (11-15/525r0)
  4. Chair overviewed the comments received for LB211. There are total 107 comments received, amongst which 34 comments are technical and 73 comments are editorial. The Approval Rate of LB211 is 93% with marginal increase from last LB.
  5. Chair reviewed the breakdown of the comments in terms of commenters. The most comments are from David Hunter who contributed 82 out of total 107 comments. The rest are from several others with single digit comments each.
  6. Chair has divided the comments into 3 documents, i.e. part 1 (11-15/527r0) containing all 82 comments from David, part 2 (11-15/528r0) consisting of 4 comments not directly relevant to the Draft 5.0, and part 3 (11-15/529r0) housing the rest 21 comments.
  7. Chair mentioned that Eugene Baik and Mitsuru Iwaoka had withdrawn their comments as announced in the 11ah email reflector. Shoukang Zheng also indicated that he would withdraw his comments and send to the reflector soon.
  8. Chair compared the current 11ah status with that of 11ac when it was planning for the sponsor ballot 2 years ago. With the help of 11ac document 11-13/320r2 “p802-11ac-report-to-ec-on-conditional-approval-to-go-to-sponsor-ballot”, he showed that 11ah is in the similar situation to 11ac at that time and 11ah could follow a similar approach in resolving Letter Ballot comments and proceeding to Sponsor Ballot.
  9. Regarding the time line and the procedure to Sponsor Ballot, Chair updated to the group that he had consulted 802.11 Chair through emails. It was suggested that a similar approach as in 11ac could be taken and see whether the comments could be resolved with minimal changes to the Draft. This will allow the group to go for another recirculation after May F2F Meeting and table it for EC’s approval for Sponsor Ballot in the July meeting. Chair asked if there is any objection to follow this suggestion in order to keep the time line unchanged. None was heard.
  10. Chair mentioned that he had scanned through the comment database and found that most of the comments are invalid and can be rejected based on the“Procedural Rejections”. Chair shared the document “Comment Resolution Tutorial” (11-13/230r1) with examples for“Procedural Rejections”.
  11. Chair planned not to assign the comments to contributors as in last recirculation. Instead, he suggested that11ah Chairs, including Chair and 2 vice chairs, would worktogether to resolve all comments, referring to the “Comment Resolution Tutorial” document. Chair asked if there is any objection to this approach in resolving the comments. None was heard.
