Approval of the San Francisco Meeting Minutes
The San Francisco meeting minutes, 07/811r0, were presented.
Motion to approve San Francisco minutes by R. Roberts
Seconded by Kursat Kimyacioglu
For: 33, against: 1, abstain: 0
Motion was passed and the San Francisco meeting minutes were approved.
Review of remaining proposal list
The list of the remaining proposals can be found in 07/795r0.
Results of the #1 ballot, in San Francisco, were summarized and presented.
J. Barr inquired the source or reference of the 20% vote requirement to pass the proposal down selection process. R. Fisher explained that document of reference is the down selection procedure 05/692r3. J. Barr pointed out the need to clarify the two distinctive rules for elimination. R. Roberts pointed out that a process that eliminates more than one proposals should be known as the special elimination vote, not a down selection vote. John Barr suggested to change the SF minutes indicating that the voting was for elimination and not down selection.
The sentence “first down selection vote” in San Francisco meeting minutes 07/811 (pg. 4) is replaced by the sentence “the initial elimination vote, step 4 given in document 05/692r3”. The sentence “first down selection” in San Francisco meeting minutes 07/811 (pg. 5) is replaced by the sentence “The elimination”.
Motion to approve the revised San Francisco meeting minutes by J. Barr, seconded by R. Roberts. Ballot outcome was for: 30, against: 0, abstain: 0
The motion was passed and the revised minutes were approved.
The revised minutes can be found in 07/811r1.
The updated list of the remaining proposal can be found in 07/795r0.

Approval of agenda
The meeting agenda in 07/821r0 was presented and opened for discussion.
The down selection number was decreased (i.e. down selection #2 was decreased to down selection #1)
Technical contribution, by J. Barr, “On 60GHz FCC NPRM”, 07/840r0, was inserted into the 3rd slot on Sept 18.
Technical contribution, by Katayama, “2Gbps Transmission Demonstration using pi/2 DBPSK Alternative”, 07/835r0, was inserted into the 3rd slot on Sept 18.
J. Barr suggested that the Special Order should be used for the down selection voting.
“Special Order” means that the voting takes place only at a specified time.

Presentation, merged proposals
CoMPA proposal presentation by H. Harada, 07/761r8
- List of contributors and newly merged proposals.
- Information on updated PHY modes, superframe format for ADD, UEP, beam forming, dev-dev communications.
Q1. R. Fisher suggested the term “CoMPA” be inserted in to the title
A1. The proposal is not only contributed by CoMPA members but also from other organizations.
Q2. Katayama commented on the difficulty to combine pi/2 BPSK and MSK in the PHY modes.
A2. Harada replied that it is possible to put them as one in the proposal.
Q3. J. Barr questioned the reason of the superframe to be limited to 2ms? What is the significance of beacon period in the superframe?
A4. In order to support applications such as beam forming, dev-dev communication etc, it is essential to fix the length of the superframe. Due to the directional communication nature, beacon period with omni communication is repeated every 2ms for ADD, beam forming applications and so on.
J. Barr said: How can TG3c vote on only Powerpoint presentations without supporting draft text? Some draft texts should be generated first. J. Gilb and P. Kinney, 802.15.4 Chair said that other 802.15 Standards were generated in the same manner.

Technical contribution
07/840r0. John Barr,"60 GHz NPRM". The FCC has issued Notice of Proposed Rulemaking, Docket 07-104, that would modify the part 15.255 rules on un-licensed operation in the 60 GHz band. This NPRM was generated by the WCAI, a group interested in providing point-to-point radio links in the 60 GHz band using higher rf power and high gain directive antennas. There is concern that the WCAI systems will interfere with 60 GHz WPANs. 07/840r0 recommends reduced rf power and station call signs which will allow the FCC to track down sources that interfere with WPAN systems. Barr obtained his contribution from Mike Lynch, Chair of 802.18, the regulatory Working Group.
