Planned to form a “Tiger Team-like” sub-group to:
Develop a list of questions to help develop a clear and definitive scheme for sharing with ITS / DSRC in the 5850 to 5925 MHz band
Meet with ITS representatives to discuss the list and have questions answered
Make recommendations for ac / ITS agreement on sharing plan
Decided that response to Ofcom consultation unnecessary

18. Architecture SC March May Mark Hamilton IETF/802 coordination
Reviewed RFC 4441 update. Trying to balance between redundant with CBPs versus enough information here.
Still open for comments – please get comments to Dorothy Stanley
Also, Operations Area working group has gotten submissions on CAPWAP, and will be considering.
Brief update on General Links (11ak) and bridging discussions
Most presentations will be in Thursday AM1 joint session
Looks like changes are needed in 802.1AC, which will need a PAR
802 Overview and Architecture Draft 1.6 sponsor ballot
Ballot deadline extended to Mar 22. Some comments addressed this week, more on telecons.
Reviewed section (Annex B.2) and comments submitted. Noted that PLCP/PMD split is being removed from , so need to describe potential changes in our architecture pictures
Architecture of APs/DS/Portals, and concepts
Reviewed submission:
Agreed Figure 5-1 (MAC data plane architecture) has issues and confusing parts. Started work toward a proposed replacement.
Need to get clarification on all (architectural) interface points within specification – all MAC-SAPs (are there more than one?), etc.

IETF/802 coordination – Dorothy Stanley
Update on joint activities between IETF and IEEE 802
Reviewed RFC 4441 update (rev4).
One comment proposed, Dorothy will carry to editing committee
Three comments needed us to do homework and submit a proposed resolution. That was done (an updated architectural picture drawn), and captured in page 15.
Reviewed all comments and their proposed resolutions. All are acceptable (with the above)
Brief update on General Links (GLK SC) and bridging discussions – Donald Eastlake
Making progress and having productive discussions
802.1Qbz Draft 0.1 has been posted on the document server
