Instructions for the WG ChairThe IEEE-SA strongly recommends that at each WG meeting the chair or a designee:

– Show slides #1 through #4 of this presentation– Advise the WG attendees that:

• The IEEE’s patent policy is consistent with the ANSI patent policy and is described in Clause 6 of the IEEE-SA Standards Board Bylaws;

• Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;

• There may be Essential Patent Claims of which the IEEE is not aware. Additionally, neither the IEEE, the WG, nor the WG chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.

– Instruct the WG Secretary to record in the minutes of the relevant WG meeting:

• That the foregoing information was provided and that slides 1 through 4 (and this slide 0, if applicable) were shown;

• That the chair or designee provided an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard

• Any responses that were given, specifically the patent claim(s)/patent application claim(s) and/or the holder of the patent claim(s)/patent application claim(s) that were identified (if any) and by whom.

– The WG Chair shall ensure that a request is made to any identified holders of potential essential patent claim(s) to complete and submit a Letter of Assurance.

– It is recommended that the WG chair review the guidance in IEEE-SA Standards Board Operations Manual 6.3.5 and in FAQs 12 and 12a on inclusion of potential Essential Patent Claims by incorporation or by reference.

Participants, Patents, and Duty to InformAll participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants:

– “Shall inform the IEEE (or cause the IEEE to be informed)” of the identity of each “holder of any potential Essential Patent Claims of which they are personally aware” if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents

• “Personal awareness” means that the participant “is personally aware that the holder may have a potential Essential Patent Claim,” even if the participant is not personally aware of the specific patents or patent claims

– “Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any other holders of such potential Essential Patent Claims” (that is, third parties that are not affiliated with the participant, with the participant’s employer, or with anyone else that the participant is from or otherwise represents)

– The above does not apply if the patent claim is already the subject of an Accepted Letter of Assurance that applies to the proposed standard(s) under consideration by this group

Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2

• Early identification of holders of potential Essential Patent Claims is strongly encouraged

• No duty to perform a patent search

Background (2/4)

• Nov 2010, CWPAN requested information regarding copyright permission for CWPAN to modify 802.11ad spec for 45-50 GHz operation

– https://mentor.ieee.org/802.11/dcn/10/11-10-1332-00-00ad-china-wpan-mmwave-liaison-w-802-11.ppt

• Jan 2011– presented official response from IEEE staff to CWPAN

• The IEEE doesn’t normally give other groups permission to modify its standards

• If China WPAN would like to propose improvements or changes to an IEEE standard we’d be happy to work with you to do that

• The next step would be to create an IEEE project proposal – can we work together on that?

– also requested more regulatory information on 45-50 GHz in China in order to determine whether to start new 802.11 project or modify 802.11ad PAR

Background (3/4)• March 2011, held a joint meeting between 802.11ad and CWPAN

– IEEE reaffirmed that IEEE will not give copyright permission to an outside organization to modify an IEEE spec. Modifications need to be done within IEEE

– CWPAN promised to provide a wish list to 802.11ad in a few months

– provided 802.11ad tutorial to CWPAN, https://mentor.ieee.org/802.11/dcn/11/11-11-0459-01-00ad-tgad-overview-for-cwpan.pptx

• July 2011– CWPAN reported that they started a new study group on 40-50 GHz in

Sept 2010, and this activity will be separate than their 60 GHz project

– CWPAN 60 GHz has a functional requirement of 3 logical channels

– presented proposal to modify TGad protocol to support coexistence between narrow channels and 11ad channels

– Bruce presented proposal for working relationship with CWPAN• Background: CWPAN wishes to modify the 11ad specification in ways that were not

known of by 11ad during its development including such items as China specific spectrum allocations and channelization

• Summary of proposal:

– Start a new project to amend 802.11+TGad, e.g. study group, new PAR, new Task Group

– Mutual exchange of documentation between 802.11 and CWPAN

– Initial ideas on Task Group meeting locations in Asia, attendance, voting rights

– New task group led by CWPAN principle

• Details regarding the operation of the Task Group require work during the study group

Submission

Notes for Wednesday Jan 18th, 8:00 – 10:00

– Suggestions made• To put in the PAR that we take 11ad and make narrow channels and band

shift

• To add “Work of this group should be substantially based on 11ad”

• To restructure the Scope to separate the 60 sub-bullets from 40-50 sub-bullets

• In 5.2 “Purpose” : modify 802.11ad so it can be used in the two bands in China

• To change “With the newly allocated frequency” to “With the soon to be with the newly allocated frequency” in 5.5 “need for project”

– Put TBD for target date

• Add CWPAN into 7.2

• 12/0141 5C will be discussed during conference call

Specifications – Questions• How much change to 11ad is required to meet the CWPAN PG4 60GHz

requirements?

– When can obtain requirements statements from PG4?

– Understood that many are in Chinese and will need to be translated

• How much change to 11 is required to meet the CWPAN SG5 40-50 GHz requirements?

– When will the 40-50 GHz spectrum allocation rules be released?

– What did SG5 request from SRRC?

– Will 11ad be an acceptable baseline for CWPAN SG5?

– Mutual exchange of documentation between 802.11 and CWPAN is needed• IEEE participants need access to CWPAN SG5 application specifications

• Understood that many are in Chinese and will need to be translated

Summary from 11/1570 on meeting locations in Asia, attendance,

voting rights• CWPANad interim meetings could be convened in Beijing

or other suitable Asian location.• CWPANad voting rights could be maintained on attendance

of CWPANad meetings only, or perhaps CWPAN and IEEE 802.11 could agree to provide each other balloting rights.

• CWPAN response on voting and attendance– CWPAN agreed the principle of maintaining the voting rights of CWPANad on attendance of

CWPANad meetings only– [Obtaining voting right]: It is suggested that participants who attend three CWPANad meetings per

year including at least one CWPANad interim meeting will obtain the voting rights of CWPANad– [Maintaining voting right]: It is suggested that participants who has obtained the voting right of

CWPANad, needs to attend two CWPANad meetings including at least one CWPANad interim meeting to maintain the voting right.

– [Note 1]: Voting right of CWPANad is not equivalent to the voting right of IEEE 802.11. To obtain the voting right of IEEE 802.11, it needs to follow the existing regulation

– [Note 2]: We expect CWPANad participants to attend at least one CWPANad interim meeting per year to ensure enough communication and better understanding with Chinese participants

Discussion in 802.11ad in Atlanta on meeting locations in Asia, attendance, voting rights

• Establishing Task group voting rights is the wrong way to go, because it splits voting rights in 802.11. It is better to have the interim CWPANad meetings be adhoc meetings with no implications on voting rights.

• Request more explanation about the need for having separate meetings in Asia given that more and more mainland Chinese attendees are actually attending these 802.11 meetings.

– Response: from past experience, many individuals from mainland China have trouble obtaining visa to travel to the US. Holding meetings in Asia will allow easier attendance.

Submission

Task Group Logistic Discussion

• Suggestion made– Prefer keeping the current voting structure of 802.11

– Consider entity-based voting or kind of hybrid voting structures

– It is possible to grant working group voting rights to those individuals in CWPAN who are active in PG4 and SG5

– Other possible changes to the voting right can be considered at the discretion of the WG chair within the limit of 802 rules.

Meetings – Questions• We have confirmed that CMMW TG meetings will be organized through CESI

• What is the best scheduling arrangement to optimize the quantity and quality of participation and technical exchanges

– Essentially all of current CWPAN PG4/SG5 members will participate in CMMW TG activities

– CMMW TG meetings will be co-located with 802.11 plenary meetings

– CMMW TG interim meetings will be held independently in Asia

• The meeting schedule for 802.11 interims and 802 plenaries are scheduled through 2014

• CMMW TG meetings will not be scheduled to overlap with scheduled 802.11 WG meetings

• If there is an 802.11 interim meeting in Asia, the CMMW TG will be co-located

• The three Asian CMMW TG interim meetings will be scheduled for 2 days ( 12 months in advance)

• If the CMMW TG interim meeting follows the 802.11 interim would you prefer the CMMW TG interim meetings be held Mon-Tues or Thur-Fri?

– CWPAN meetings will be co-located

• 802.11 interim meetings announced at least 45 days in advance do not require a quorum for voting

Introduction of CESI• China Electronics Standardization Institute(CESI) founded in 1963 is a

professional institute for standardization in the field of electronics and IT industry under China Ministry of Industry and Information Technology (MIIT)

• CESI has been playing a significant accelerating role in disseminating and applying standards, promoting the development of the industry, and international exchange and cooperation, with:

– having established laboratories, certification bodies and working stations authorized by the government and accredited by the authorities;

– taking charge of the centralized management for 54 national technical mirrors to IEC TC/SCs and ISO/IEC JTC1/SCs;

– having held 11 secretariats of national standardization technical committees, including CWPAN

– having established cooperation relationship with some international standardization organizations and well-known international bodies

Voting rights - BaselineRules Baseline

•A working group can authorize more than one Interim meeting between plenaries.

•An interim announced at least 45 days in advance does not have any quorum requirement

•WG voting rights are obtained and maintained by attending meetings and voting on WG draft ballots

•Under the current 802 WG rules an individual who attends only 802.11 interim meetings cannot obtain or maintain 802.11 WG Voting rights

•The WG11 chair does have the power to grant or reinstate voting rights if the circumstances warrant such an action

•802.11 only grants voting rights on a WG basis – there are currently no provisions for task group only voting rights

Working assumptions

•It is expected that 802.11 members will broadly participate in multiple TG activities and will be broadly interested in the “seamless” integration of new amendments into the whole

•The Chairs of the CMMW TG project will be able to attend both regular 802.11 WG interims and plenaries plus Asian based CMMW TG interim meetings

– However a substantial portion of the CMMW participants live in China, plan to attend the CMMW TG interims held in China but will not be able to travel to the US for 802.11 WG Meetings

Voting in Meetings

Rationale

We want participation from all members so we need the meeting to have importance (i.e. voting)

Proposal

CMMW TG meetings should be conducted such that qualified voting members will be able to conduct binding votes (not just straw polls)

January 2012


doc.: IEEE 802.11-12/0121r4

Submission

Attaining/Retaining Voting rightsAssumption

Credit towards working group voting rights will be granted from attendance at Asian Task Group interim meetings (when not co-located with normal 802.11 interim meeting, but it cannot be double counted if the participants attend the normal 802.11 interim meeting towards WG voting rights)

802.11 voters, that never attend a CMMW interim meeting, will have CMMW voting rights.

New considerations

Should 802.11 create a new class of Voting rights that are task group specific? (i.e. CMMW TG voter)

Voting on Drafts

• Does a CMMW TG voter vote on all other WG drafts?

• If CMMW TG members had such rights would they be included in WG ballots only on matters pertaining to the CMMW TG?

• Is voting by all CMMW TG members on all CMMW drafts required to maintain voting rights?
