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.

Note: WG includes Working Groups, Task Groups, and other standards-developing committees with a PAR approved by the IEEE-SA Standards Board.

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

• 11-13-0436r0 IEEE 802.11aj April meeting minute has been unanimously approved by TGaj group

• The CFP (60GHz) document 11-13/0643r0 was presented by Xiaoming Peng

– Eldad commented that the complete proposal presentation can be considered to be extended to January 2014 session in case some participants are not able to get Visa in time to attend November session in Dallas, USA.

• Plan for “call for nomination of TG Technical Editor– Xiaoming suggested an initial proposal to open up the call for nomination of TG

technical editor after July meeting and elect TG TE in Sept session.

– Eldad suggested to defer the decision as the group has chance to vote for the best suitable candidate after seeing the proposal submission and presentation

– Xiaoming will review the timeline of the election of TG TE after receiving the submission of “intent of submission of proposal” by August 30, 2013

• Spatial Sharing Mechanism in 802.11aj (60GHz) -11-13/0720r1 was presented by Francois Chin

– Andre Bourdoux from IMEC commented that the signal transmitted in sidelobe of the main beam may cause interference and subsequently affect the accuracy of the algorithm proposed

– Francois replied that the proposed algorithm only gave the initial recommendation of the spatial sharing and it still needs to carry out the measurement as what 802.11ad does to determine if the spatial sharing can be done.

• MAC protocol to support dynamic bandwidth -11-13/0433r1 was presented by Xiaoming Peng

– Zhang Hongyuan from Marvell asked if there is any mask requirement for 1.08GHz band

– Xiaoming replied that there is no such requirement at the moment, however, it will be very similar to the mask requirement for 2.16GHz

– Andre asked if there is any requirement for the time slot between large band and small band

– Xiaoming responded this time slot is allocated to allow the band switch.

– James Yee from MTK clarified the difference between NP and BHI period used in different slide and if there is a requirement that NP1 should be allocated to the master PCP?

– Xiaoming replied that the general term should be notification period (NP), however, in some examples, Beacon Header Interval (BHI) can be used for transmission over NP. It is agreed that NP1 should be used for the master PCP, i.e., PCP/AP 1 used in the example.

– James also suggested it will be helpful if the interpretation of the new frame from the legacy 802.11ad device point of view is provided.

– Bo Sun from ZTE clarified SBBI duration in small band is periodic

– Xiaoming confirmed that the SBBI is periodic within small band.

• Channel Models for 45GHz WLAN Systems – 11-13/0794r0 was presented by Haiming Wang– It will be helpful for a better understanding if a presentation can be prepared

for the comparison of channel model between 60GHz and 45GHz

• Backhaul-usage-model-proposal update - 11-13-0177r3 was presented by Ogawa-san– Xiaoming asked if MG-RT uses directional transmission or omni-

transmission. If MG-RT is omni-transmission, then AP and STA which are communicated via MG-RT should be within the coverage of MG-RT by using the omni transmission.

– Ogawa-san replied that MG-RT uses omni-transmission, will further evaluate the situation

– Chen Qian further asked if MG-RT uses omni-transmission, will it interference other transmission among STAs.

– Ogawa-san will further evaluate the situation

– Bo Sun asked if MG-RT is full duplex or half-duplex? – Ogawa-san replied that MG-RT is full duplex– Francois Chin further further commented that if MG-RT is full duplex, it

may cause self-interference. – Ogawa-san will further evaluate the situation
