  2. 802.15 IEEE 802.15 Working Group for Wireless Personal Area Networks TG3 Status Report January 2001, Monterey, CA USA John Barr, Motorola

  3. Agenda • Goals of January Meeting • IEEE 802.15.3 PAR • Status and plans for TG3 • Coding Selection Process and Voting Rules • Coding Presentation and Voting Times • January Document List John Barr, Motorola

  4. Goals of the January Meeting • Conference call status, including approval of any ad hoc business. • Resolution of MAC and PHY issues. • Review interfaces between MAC and PHY. • Begin writing draft standard – Editorial reviews. • Establish operating plan for conference calls between January and March. • Build ballot pool. John Barr, Motorola

  5. IEEE 802.15.3 PAR • Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for High Rate Wireless Personal Area Networks (WPAN) • … wireless connectivity with fixed, portable and moving devices within or entering a Personal Operating Space (POS) (up to 10 meters in all directions enveloping a person) • … interoperability or coexistence with other 802.15 TG • … coexistence with other wireless devices in conjunction with Coexistence Task Groups such as 802.15.2 • … low complexity, low cost, low power • … >20Mbps to satisfy a set of consumer multi-media industry needs for WPAN communications. John Barr, Motorola

  6. Status and Plans for TG3 • Construction of Initial Draft Goal: everything you need to know to construct the lower layers of high rate WPAN • Schedule Goal: Produce a Standard by the end of 2001 or early 2002 • Next Steps Goal: Finalize high-rate coding methods, January, 2001. Working Group draft, May, 2001. Sponsor ballot, November, 2001. John Barr, Motorola

  7. Teleconference Calls • Goal: Document results of Tampa selection process, organize and write proposed standard clauses, determine how to select high-rate coding methods, define interfaces between MAC and PHY. • 802.15.3 General: Held every Tuesday between F2F meetings. • PHY Committee: Every Thursday. • MAC Committee: Every Tuesday following general 802.15.3 call. • System Committee: No calls scheduled. Email work. John Barr, Motorola

  8. Monday: Progress report Presentations on proposed standard clauses: Monday: Clause 5 – Kinney Tuesday: Clause 7 (frame formats) Gubbi Tuesday: MAC SDL Model – Heberling Tuesday: Clause 9 (SC-TDMA Access) Roberts MAC Issue Resolution: Questions for each editor’s clause work MLME SAP interface Non-802 MAC SAP interface (15.1 and dot_11) MAC/PHY Issue Resolution: PHY SAP, PLME SAP, PLME MIB? Impact of long preamble and FEC coding schemes on effective data throughput rate MAC Summary John Barr, Motorola

  9. Systems Summary • Review list of SAP primitives currently used in 802.11 and modify these as needed to support 802.15.3 • Review the strawman PLCP signal field format and modify as needed to support 802.15.3 • Determine if PHY and MAC are far enough along to achieve closure on the SAP primitives. John Barr, Motorola

  10. PHY Summary • Review results from PHY committee conference calls • Select a coding method for the higher order modulations • Resolve as many undetermined issues as possible • Document all remaining issues and determine a course of action to resolve them. John Barr, Motorola

  11. Coding Proposal Presentations • Monday – 3:51 PM – Karaoguz • REF • Monday – 4:21 PM – Dabak • REF • Tuesday – 8:02 AM – O’Farrell • REF John Barr, Motorola

  12. Coding Voting Times • Wednesday – 9:00 – 3-2 • Panel Discussion on Remaining 2 Methods • 9:10 Each proposer has 2 minutes for position statement with 13 minute Q/A • Wednesday – 9:40 – 2-1 • Coding Confirmation Vote • Wednesday 9:50 Confirmation Role Call Vote • 10:31 Resolution of No Votes (if necessary for 75%) John Barr, Motorola

  13. IEEE 802.15.3 Voting Process (1 of 2) • a) for the voters, by ballot vote, to vote for one proposal or none of the above. (Voting record will be posted following the vote.) • b) the proposal (or proposals in case of a "tie") receiving the least votes is eliminated • c) the process continues with a vote as in "a" and "b" eliminating proposals one by one • each time the number of proposals in the eliminating process has been reduced to four and two a panel discussion shall be held with the remaining proposers as panel members. The length of discussion shall be limited to 15 minutes times the number of remaining proposals. Discussion shall be limited to voting members and the presenters (or their designate). John Barr, Motorola

  14. IEEE 802.15.3 Voting Process (2 of 2) • d) when one proposal is left the voters shall vote (roll call) for the proposal or none of the above and the proposal shall be required to achieve a 75% majority in order to be submitted to the working group as a recommendation. If the remaining proposal fails to achieve a 75% majority, the members who voted "no" shall be requested to state why they voted no and what would be required to change their vote to an affirmative vote. The proposer shall have an opportunity to respond to the concerns of the no voters. After which a roll call vote will be taken to approve the proposal. • e) if the last remaining proposal fails to receive 75% majority, the process shall begin again with the proposals remaining after 50% were eliminated. John Barr, Motorola

  15. Panel Process • Total time for panel is 15 minutes * number of remaining proposals • Two minute position statement from each member of the panel (optional) • Q&A – Questions may only be asked by voting members. • FIFO queue of questions will be kept by Chair. • Only one question per position in the queue. • Questions must be stated in no more than one minute • Answers must be stated in no more than two minutes • No motions will be considered during the panel. John Barr, Motorola
