1. 802.11m ReportMarch 2004 Darwin Engwer, Nortel Networks

2. Goals for March 2004 • Interpretation requests • Draft responses to requests and forward to WG • Respond to any comments re the change of the PAR from an amendment to a revision of the standard • Develop updates to standard • Begin work from spreadsheet of work items • Volunteers needed Darwin Engwer, Nortel Networks

3. Submissions? • Are there any submissions? • None • Are there any new interpretation requests? • Yes, two. Darwin Engwer, Nortel Networks

4. Proposed Agenda • Review IEEE Patent Policy • Review interpretation request procedure • New business • Review interpretation requests received • Draft responses to interpretation requests • Forward to full WG • Review any comments on the revised PAR • Begin work on updates to standard • Review incoming draft amendment 802.11m 0.1 • Confirm draft 0.1 as the basis for ongoing work • Adjourn Darwin Engwer, Nortel Networks

5. Motion to adopt Agenda • Moved: to adopt the agenda • Mover: Keith Amann/Haixiang He • Passes: unanimous Darwin Engwer, Nortel Networks

6. IEEE-SA Standards Board Bylaws on Patents in Standards The slides from this file were shown and read aloud to the attending members: http://standards.ieee.org/board/pat/pat-slideset.ppt Darwin Engwer, Nortel Networks

7. Attendance • Remember to sign in to the attendance server Darwin Engwer, Nortel Networks

8. Comments on Revised PAR • One comment was received wrt the Revised PAR. • The response text is in document 4/355r1. • Motion: To adopt the response in document 4/355r1 to Bob Grow’s comment on the revised TGm PAR. • Mover: Terry Cole/ Haixiang He • Vote: Passes unanimously Darwin Engwer, Nortel Networks

9. Motion to Forward to WG • Motion: to request the working group to accept and forward the comment response contained in document 04/355r1 to Bob Grow as the official response of the 802.11 working group. • Mover: Terry Cole/ Haixiang He • Vote: Passes unanimously Darwin Engwer, Nortel Networks

10. Comment Cover Letter • As a result of the working group approving the comment response at the mid week plenary, document 4/393r1 was created to send to Bob Grow. Darwin Engwer, Nortel Networks

11. Interpretation Procedure • http://standards.ieee.org/reading/ieee/interp/ • Send email to Linda Gargiulo (l.gargiulo@ieee.org) • IEEE forwards requests to the WG • WG classifies as a request for an explanation, or a formal interpretation request • WG responds Darwin Engwer, Nortel Networks

12. Interpretation Requests • Adopting beacon parameters in an IBSS • Reinitializing the 802.11b scrambler for header and psdu fields Darwin Engwer, Nortel Networks

13. Interpretation Request #1 11.1.4 says: "A STA receiving such a frame [a beacon] from another STA in an IBSS with the same SSID shall compare the Timestamp field with its own TSF time. If the Timestamp field of the received frame is later than its own TSF time, the STA shall adopt all parameters contained in the Beacon frame.” What is the meaning of "all parameters" in this context? It's clearly not just the TSF timer, or there would be no need to say "all" parameters. And if it includes information carried in IEs, does it, or does it not, include IEs which the STA does not recognize? Darwin Engwer, Nortel Networks

14. Interpretation Response #1 • see doc 4/425 Darwin Engwer, Nortel Networks

15. Motion to adopt 04-425 • Moved: That document 04-425r0 be adopted as the response to the interpretation request regarding “Adopting beacon parameters in an IBSS”. • Moved: Jon Rosdahl • Seconded: Keith Amann • Vote: unanimous Darwin Engwer, Nortel Networks

16. Motion to forward to WG • Motion: to request the working group to accept and forward the interpretation response contained in document 04-425r0 to Linda Gargiulo at the IEEE office as the official response of the 802.11 working group. • Moved: Keith Amann • Seconded: Jon Rosdahl • Vote: unanimous Darwin Engwer, Nortel Networks

17. Interpretation Request #2 • I have doubt regarding scrambling in 802.11b. For each packet we have 3 fields (plcp header, plcp preamble and psdu). while scrambling plcp preamble we are initializing with particular seed based on preamble. What about header and psdu fields. We have to be reinitialize the scrambler state or not? Darwin Engwer, Nortel Networks

18. Interpretation Response #2 • IEEE STD 802.11b-1999 (reaffirmed 2003) clearly states the requirements for scrambling in clauses 15.2.3 and 15.2.4. Since the standard is clear on this matter, no interpretation is required. Darwin Engwer, Nortel Networks

19. Motion to adopt 04-426 • Moved: That document 04-426r0 be adopted as the response to the interpretation request regarding reinitializing the 802.11b scrambler for header and psdu fields. • Moved: Jon Rosdahl • Seconded: Keith Amann • Vote: unanimous Darwin Engwer, Nortel Networks

20. Motion to forward to WG • Motion: to request the working group to accept and forward the interpretation response contained in document 04-426r0 to Linda Gargiulo at the IEEE office as the official response of the 802.11 working group. • Moved: Keith Amann • Seconded: Jon Rosdahl • Vote: unanimous Darwin Engwer, Nortel Networks
