4. 21-06-0832-00-0000 802.11k – Radio Resource Measurement Measurements provided for runtime adjustment of radios Available to internal STA components, higher layers, and external devices 802.11m – Maintenance (compilation of all approved amendments) Work is now complete: will become IEEE Std. 802.11-2007 in March 2007 802.11r – Fast BSS Transition Between BSSes within the same ESS Relies on 802.11k (especially neighbor reports) 802.11u – Interworking with External Networks MAC changes to accommodate, among others, 802.21 Relies on 802.11k and 802.11r; has scope agreement with 802.11v Joint meetings with 802.21 this week; more in January(?) 802.11v – Wireless Network Management Management protocol additions AP-AP negotiations; load balancing; additional access controls Relies on 802.11k 802.11w – Protecting Management Frames Security for management frames, including broadcast frames Relies on 802.11k, 802.11r and perhaps 802.11u 802.11 Groups Related to 802.21 (the usual suspects)

5. 21-06-0832-00-0000 802.11s This Session (VERY quick overview of this week) Major controversy over CCF Limited mesh-only change that affects 802.11e QoS Including EDCA, as would not obey NAV protection Major problem for legacy equipment TGs approved motion to pull CCF out of draft Passed by bare 75% vote: 45:14 Approved motion to create Draft D0.06 Will be issued this afternoon Likely vote to go to Letter Ballot again (But I had to leave to attend 11u.)

6. 21-06-0832-00-0000 802.11u This Session (Another VERY quick overview of this week) This morning: one requirement left unfulfilled: R12N8 Support of informing STA of what online subscription methods are supported by the local network Approved motion to change its status to “Optional” Therefore, all requirements are now fulfilled (at least in part) by current draft Approved sending liaison letter: 802.21 – asking to review R12N8 for applicability to 802.21 Actual transmittal still needs approval by 802.11 WG tomorrow Informal request from 802.11u to 802.21 in the meantime Moved from Step 13 to Step16 of Downselection Process Voted to approve new Draft D0.02 for Internal Review But expanded “Internal Review” to include non-voters  Especially 802.21 members

7. 21-06-0832-00-0000 802.11r This Session Re-circulation ballot Issued re-circulation ballot in September Held ballot resolution ad-hoc in October Finished all comments this week Issuing a re-circulation ballot after this week’s meeting Drafts Draft coming out today is Draft 3.1 Current responses are in 11-06-0537-34-000r-d2- comments.xls

8. 21-06-0832-00-0000 802.11r This Session, 2 Controversy #1 *Normative* state machines in the amendment One problem: same information in two places TGr voted to keep the state machines normative Controversy #2 Pull model Text inserted by bare 75% vote in Melbourne Text removed from the draft this meeting –Significant portions of Draft 3 reverted to Draft 2.2 –Draft 3.1 incorporates these changes

9. 21-06-0832-00-0000 802.11r Timeline PAR was approved over 2 years ago Another Ad-Hoc Comment Resolution Meeting Scheduled February 21-23, 2007 Circulations Next recirculation ballot will be issued tomorrow Possible to go to Sponsor Ballot after March, 2007 Plenary Limitations IETF support : Key Management Goal is still to have a new RFC issued within a year Dependency on 802.11am 802.11am will become IEEE Std. 802.11-2007 in March, 2007 802.11k dependencies If 802.11k doesn’t finish first, arrangement is to copy the portions of 802.11k that 802.11r needs Key point: 802.11r sponsor ballot still before 802.21 sponsor ballot But the race is getting close
