Tuesday, 16/March 2010– Session 1
08:00 Meeting was called to order by chair Art.
Igor Dotlić agreed to take the minutes.
Art asked for approval of the previous meeting minutes (10-0083-01).
Art presented “Group Opening Report” (10-0168-00).
Nancy: Those who are out of the merging process would like to see the process through normative text before and after the merger.
Ryuji: We should upload drafts of normative texts as soon as possible; have an agreement as soon as possible.
ET Won: Before uploading the normative text we need to finish the merging.
Ryuji: We should define the timeline of the baseline agreement.
Anuj: First step is to receive normative text, (technically) vote it in the group, then everybody can do the editing and we could have final version in the May meeting.
Nancy: Will there be down-selection? What happens where there is technical vote and there is no agreement.
Art: The normative text is now discussed by the private group which is majority of TG6, thus it won’t have problem of voting of the text (if all in the private group agree).
ET Won: We should discuss voting on the text once the work on the text is done (all subcommittees’ jobs finished).
Anuj: We can vote each of the parts individually.
Ryuji: We can simply combine all parts together, once they are finished.
Anuj: Nancy, can you state your affiliation?
Nancy: I am self employed, no affiliation.
Sri: We should vote in each of the individual text and then the group can change things and get the final draft. HBC is far behind other subgroups in writing normative text.
Ranjeet: I would like to state that HBC is also 95% ready. MAC and Phy are interlinked and thus we should vote them in all together.
Chuck: We should keep the four columns separated. There is no HBC tech report, while there is one for UWB and narrowband Phys and there is regulatory compliance ambiguity for HBC.
Anuj: There is time to resolve conflicts and remove redundancies.
Sri: There is some disagreement in one section and I think that other sections should not be delayed because of that section.
Kiran: We are finding a lot of dependences between UWB Phy and MAC; that is why we would like to have a single draft to vote on.
Art: Once we vote on something it does not mean that we cannot change it any more.
Neel: From a point of view of somebody who needs to show some progress to the bosses, I am in favor of voting the parts individually.
Ranjeet: Why we don’t combine all the drafts individually and vote on a single draft.
Art: Which of the subcommittees can present their drafts?
Anuj: I can present the narrowband Phy.
Marco: UWB may be ready tomorrow.
ET Won: I want to resolve comments made by SMA to HBC, before uploading the HBC draft.
Ranjeet: Maybe today in PM seassion (MAC draft).
Art recessed the session.
Tuesday, 16/March 2010– Session 2
10:30 Meeting was called to order by chair Art.
Art went over agenda for the rest of the day and presented changes in TG6 agenda (10-168-01, p.5).
Anuj: Will we vote on this meeting or not?
Art: We may.
Art recessed the session.
Tuesday, 16/March 2010– Session 3
13:30 Meeting was called to order by chair Art.
Anuj Batra presented “Draft text for Narrowband Physical Layer” (10-0195-00).
Jin-Meng Ho presented “MAC and Security Baseline Proposal – Normative Text” (10-0196-00).
Art recessed the session.
Tuesday, 16/March 2010– Session 4
16:00 Meeting was called to order by chair Art.
Marco Hernandez and Kiran Bynam presented “Normative Text of the UWB Phy of TG6” (10-0198-00).
Jin-Meng: Some clarifications regarding MAC. Length of the payload should be defined similar to narrowband Phy.
Jin-Meng: Does Hybrid ARQ require any interaction with MAC?
Marco: Yes, it is cross-layer design.
Ranjeet: High QoS definition?
Marco: We do not have the definition yet.
Ranjeet: I think you should collaborate with MAC people about this definition.
Marco: Yes.
Shung-Pak: What is status of the non-coherent Phy in high QoS?
Marco: The non-coherent Phy is optional in the high QoS mode and diff. coherent is mandatory.
Art recessed the session.
Wednesday, 17/March 2010– Session 5
08:00 Meeting was called to order by chair Art.
Jahng Sun Park presented “Samsun-ETRI’s EFC Proposal for HBC PHY” (10-0201-01)
Anuj: The proposal lacks important technical data; how do I know your header is more robust than the payload?
If I look at this document compared to the other two there is a lot of data missing – crystal tolerances, spectral masks…
Jahng Sun Park: We will include this data in next versions.
Chuck: Paragraph 3.2. – Can you provide more data about transmitter? Paragraph 1 – Are you stating that this proposal is compliant with all tech. requirements? How about 3m range requirement?
Jahng Sun Park: We considered only on-body communication.
Chuck: This system is not in the group’s regulatory document.
Jahng Sun Park: We tested our devices for FCC compliancy for different bands.
Chuck: Did you talk with FCC on how this kind of devices can be tested?
Jahng Sun Park: No, we are currently working with Korean government.
Chuck: We may go through 802.18 and see their compliance with FCC.
Anuj: I don’t agree with coexistence testing results.
Jahng Sun Park: We looked into 400 MHz band and reached the conclusion that there is no significant interference.
Anuj: There is still a lot more analysis needed to be done in order to make this conclusion.
Ryuji: Our medical devices companies are very worried about compliance. I hope you can show compliance results next time.
Nancy: Maybe Medtronic and other guys that brought up some issues should spend some time with HBC group and try to go over those issues together.
Art recessed the session.
Thursday, 18/March 2010– Session 6
08:00 Meeting was called to order by chair Art.
Art reviewed changes in “Group Opening Report” (10-0168-02).
Al: Can you do a straw-poll on how many voting members will be there in Beijing.
Art: OK; result 26.
Dave Evans and Ray Krasinski presented: “Initiative to enable 802.15.4 to Work in MBAN Spectrum” (10-0129-01-wng0).
Al: I am concerned of the two medical PARs being generated here.
Bob: This is extending 15.4 for the medical usage.
Ranjeet: How will ordinary 15.4 devices be prevented from using this band?
Dave Evans: This is licensed band and only doctor prescribed devices will be allowed to operate.
Didier: You have different channelization than 15.4. (1 MHz channel).
Art: This is just a study group; this kind of issues will have to be resolved before it becomes TG.
Ray: We would like as little change as possible.
Art recessed the session.
Thursday, 18/March 2010– Session 7
10:00 Meeting was called to order by chair Art.
Huan-Bang Lee presented “WiBAN-SMA Merge Announcement” (10-0215-00).
Motion: Instruct the technical editor to combine documents: 10-0195-02, 10-0196-02, 10-0198-01, 10-0201-01 into a single TG6 baseline draft
Mover: E.T. Won
Seconder: Huan-Bang Li
Discussion:
Chuck: p.3, In order to access HBC/EFC regulatory and safety compliance more analysis has to be done.
Ranjeet: How will changes be done on this document?
Art: I plan to initiate discussion about this later.
Voting: Yes: 56; No: 1; Abstentions: 0.
Art recessed the session.
Thursday, 18/March 2010– Session 8
13:00 Meeting was called to order by chair Art.
Art: Someone having updates on MPR for MBAN?
Dave: For now ball is still in court of those who want to promote MBAN and use it.
Art: Are there comments on how to put 4 normative texts in one document?
Anuj: We shouldn’t worry about that. We should put things in the IEEE format and then resolve comments.
Art: Any comments from the tech. editor of how to proceed?
Daniel: The sub-technical editors will use their leverage in subgroups to get comprehensive document.
Anuj: My comment to Daniel is to keep sections from subgroups separate, otherwise things can get blurry.
Art: planning of May meeting.
Chuck: One thing is to look at is the revised regulatory document with HBC included.
Thursday, 18/March 2010– Session 9
