Participants, Patents, and Duty to Inform July 2009 doc.: IEEE 802.11-09/0840r0 Participants, Patents, and Duty to Inform All participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants [Note: Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2]: “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 “Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any other holders of 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 Early identification of holders of potential Essential Patent Claims is strongly encouraged No duty to perform a patent search David Bagby, Calypso Ventures, Inc.

Other Guidelines for IEEE WG Meetings All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. Don’t discuss the interpretation, validity, or essentiality of patents/patent claims. Don’t discuss specific license rates, terms, or conditions. Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings. Technical considerations remain primary focus Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets. Don’t discuss the status or substance of ongoing or threatened litigation. Don’t be silent if inappropriate topics are discussed … do formally object. --------------------------------------------------------------- See IEEE-SA Standards Board Operations Manual, clause 5.3.10 and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

MLME-RESET, versus MLME-JOIN and MLME-START Topic out of REVmd: No apparent requirement for an “initial” MLME-RESET, in 802.11. So, what is the initial state? Many MIB attributes describe taking effect at next MLME-JOIN or MLME-START. MLME-JOIN occurs at each BSS transition MLME-START occurs at less well-defined points, seems to require an MLME-RESET first Do these attributes really take effect at these points, or at the MLME-RESET? How about other state information, such as security association, block ack agreements, etc., etc.?

ARC Future Activities & sessions ARC SC meets when a specific focused task is requested of the SC for which the is sufficient volunteer interest. Continue work on architectural models, and liaison with TGs in development of their architecture as appropriate Consider YANG/NETCONF next steps Investigation of WUR architecture topics; may lead into “split” PHYs (LC, 28 GHz (Phazr)) Will also follow 802.1/802.11 activities on links, bridging, and MAC Service definition – “What is an ESS?”, for example MLME-RESET, versus MLME-JOIN and MLME-START Monitor/report on IETF/802 activities, as needed Monitor/report on IEEE 1588 activities and 802.1ASrev use of FTM, as needed If you have ANY other topic that you would like ARC SC to consider, contact the SC chair.

Planning for September 2018 Plan for three individual meeting slots Usual slot on Wed AM1 Another 2 slots for standalone ARC work (Monday/Tuesday?) Plus Joint sessions: Another with TGba? Individuals interested in ARC work are encouraged to also attend AANI SC sessions Teleconferences: Schedule with 10 days notice

Prep for TGba joint session Suggest: Review of slides 29-31 (in this deck) Review of “802.11ba Architecture discussion” (Ganesh Venkatesan) 11-18/0884r1 Review of “Definition of WUR Mode” (11-17-0972r2) Review of Specification Framework (11-17/0575r11) Review of inputs from teleconferences: 11-18/1016r0, 11-18/1017r0, 11-18/1020r0

Thursday, July 12th, PM2 Joint session with TGba and ARC

TGba architecture topics Investigation of TGba (WUR) architecture topics may lead into discussion of other “split” PHYs (LC, 28 GHz (Phazr)) Presentations: “802.11BA topics related to ARC” (Ganesh Venkatesan) 11-18/0533r2 “11BA Arch Discussion” (Mark Hamilton) 11-17/1025r0 Review of “802.11ba Architecture discussion” (Ganesh Venkatesan) 11-18/0884r1 Review of “Definition of WUR Mode” (11-17-0972r2) Review of Specification Framework (11-17/0575r11) Review of inputs from ARC teleconferences: 11-18/1016r0, 11-18/1017r0, 11-18/1020r0 Also see following slides TGba is still maturing, through the SFD process. Started in March session with substantive discussions

TGba architecture comments/answers to questions in 11-17/1025 (from July 10, 2017 TGba) Yes, fully independent PHY Probably independent MAC? Always co-located with AP or non-AP STA – a “companion” radio No MAC Address (?) WUR MAC (assuming it is independent) does need to coordinate with the main MAC. Main MAC negotiates a WUR ID on WUR’s behalf, for example. And, power on/off needs to be coordinated between them – might be through higher layer entity, though (?) WUR does not associate to the BSS (it doesn’t have a MAC Address) WUR only runs in 2.4/5 GHz. But, can work with all PHYs (maybe?) Mesh, IBSS, OCB uses are TBD in the future, not now

TGba architecture new questions (from July 12, 2017 ARC) Does every WUR stack have an individual “ID” (“WUR address”)? Or, could a given WUR stack be only addressed using a “group ID” in some scenarios? How are WUR ID’s made globally unique, or are they? What about overlapping WUR coverage? Prevented using the same solution as security protections? Prevented through selection of different sub-carriers? How does the WUR stack become aware of ongoing NAV protections? RX doesn’t need to know. What about the TXr? For protection – how much of a legacy frame header is sent? Just PHY header? Some MAC header (addresses? NAV? Etc) Is there any sharing (necessarily, as part of the design, not implementation choice) of RF front-end? What happens when the Main stack wakes up? Does it still have an association? Is it in some power save state (which)? “Yes, fully independent PHY” – is that for the RX side, or the TX side? What about error recovery? STA goes out of range? What if the AP changes (DFS, ITS, etc)?

TGba architecture potential assumptions (from July 12, 2017 ARC) How does the WUR stack become aware of ongoing NAV protections? RX doesn’t need to know. The master’s Main stack runs the usual medium access, and wait until it has a TXop, then triggers the WUR to TX. On the RXr, only one stack (WUR or Main) are active at a given point in time. When the Main stack wakes up, it still has an association and is in a power save state (a new “WUR” power save state). The Main stack TXs, which is the indication that the wakeup was successful and completed. There are 100% RX WURs, at the sleeping node. There are TXrs, on the master node, and these are therefore (potentially) different architecturally. The WUR “wakeup” frame does not NAV protect to cover the sleeping device’s Main radio waking up and TXing. Review 11-17/972 to confirm/before proceeding on the above
