2.       Actions arising from Sept session

a.       WUR PAR

                                                               i.      Was pre-submitted to NesCom agenda, and accepted.

                                                             ii.      PAR and 5C were circulated to EC

b.      Liaison to 3GPP was sent.

                                                               i.      I have been in receipt of various emails indicating that it was discussed in 3GPP.

                                                             ii.      3GPP SA determined: (SP-160737)

•       SA considers it desirable to continue to improve WLAN integration in the 3GPP NextGen System in future

•       There are related objectives in on-going stage 1 and stage 2 work.

•       From Rel-6 to Rel-13, there was continual advancement of features to improve integration of WLAN with the 3GPP system.

•       SA defers to PCG to further discuss how cooperation between IEEE 802.11 and 3GPP TSGs and WGs can be pursued beyond the existing collaboration (through LS exchanges).

•       In particular, SA requests PCG consider all aspects of the incoming LS concerning IMT-2020 submission and to provide guidance.

 

 

                                                            iii.      The discussion in RAN was:

RP-161804   IEEE 802.11 Working Group Liaison on the role of WLAN in IMT-2020                                      IEEE 802.11

                   (IEEE 802.11-16/1101r10; to: RAN, SA; cc: IEEE 802 EC, IEEE 802.1 WG;

                   contact: IEEE 802.11 WG Chair)

                   received on 17.09.2016; RAN action requested

                    presented by Broadcom

                    RAN chair: Coordinated with Erik (SA chairman) and Adrian (PCG secretary). The LS will be answered in two

 

                    steps:

                    1.  From Technology standpoint, TSGs should discuss whether it is desirable to consider mechanisms that can

                    further/better integrate 3GPP and 802.11 systems, at radio level (RAN) and core network level (SA). And report to                    PCG

 

                    2.  PCG should then discuss how the two groups can cooperate.

                    If we can, we could answer on the first point.

                    Intel: We included WLAN interworking already

                    Ericsson: we have the requirement for NR and WLAN interworking already so no doubt about this

                    Qualcomm: what is "better integration and interworking" is not so clear from the LS

                    RAN chair: So from RAN point of view: "From RAN point of view it is desirable to discuss radio-level integration

                    between 3GPP/NR and 802.11"?

                    Deutsche Telekom: we need to avoid multiple solutions

                    Nokia: to point 1. we do not need to report to PCG

                    RAN chair: this is just reporting as usual from RAN as PCG has not received this LS

                    BT: what is the point of 2.? We are interworking already with IEEE.

                    RAN chair: submission to ITU-R is done by OPs and so this is a novelty to have a joint submission

                    Ruckus: interest to work jointly together not as an individual

                    RAN chair: yes, an MoU can only be discussed at PCG

                    Qualcomm: LS talks about aggregation not integration, radio level interworking is proably a better term

                    Nokia: what is the motivation of the IEEE proposal?

                    RAN chair: So regarding 1. can we agree: From RAN point if view it is desirable to discuss radio-level integration

 

                    between 3GPP/NR and 802.11 system?

                    Intel: IEEE had a committee to discuss options for submission for ITU-R, they had 4 options and the committee

                    suggested a joint proposal

                    Ericsson: for LAA we went through the interworking already and the tools we have (exchanging LSs and rapporteurs)

                    were already successful

                    Telecom Italia: joint cooperation with IEEE is useful

                    Blackberry: supports also joint cooperation with IEEE 802.11, are we sending an LS from RAN?

                    RAN chair: no, will inform PCG about the outcome from RAN and they can then decide how to go forward

                    Huawei: no joint submission indicated in the LS

                    RAN chair: it is clear from the LS

                    Broadcom: SA2 is organizing a workshop with BBF on fixed-mobile ocnvergene is one example for cooperation

                    conclusion: RAN chair will inform PCG about RAN conclusion: From RAN point of view it is desirable to discuss radio-level integration between 3GPP/NR and 802.11 system.

 

c.       Pending actions:   802 working on a liaison to 3GPP PCG.

                                                               i.      Involved:  Joseph, Adrian, Paul N, Jon, Dorothy, Glenn Parsons, Roger Marks, Max Riegel

1.       Action: Adrian chase Marc

                                                             v.      P802.11ah to RevCom – report is 11-16/777r6

9.       Status of liaison on RSSI measurement

a.       Peter:  2007 doc 2909 is OTA procedure for measurement of RSSI

b.      2551r3 is characterization of path loss.

c.       We don’t do any conformance testing.  No point in citing a test in 802.11.

d.      What is 802.11 relationship with 3GPP, given that we don’t specify tests?  3GPP is looking for a regulatory.

                                                               i.      Possible outcomes: 

1.       Update in REVmd

2.       WFA liaison indicating demand (or lack of it) for tests in 802.11

10.   Possible discussion Items for Nov

1)      Guidelines on authoring, when you can update somebody else’s document, or change the author field.  From the minutes:

Document Revision Authorship

·       C:  I noticed that the AANI liaison was originally authored by the IEEE 802.11 WG chair, but during revisions, the authorship changed. This is rather confusing and I wonder if there is a guideline for when changes are made to the same document number.

·       Chair: From my own personal view, it should reflect the author who made the changes.  If there is some doubt, a new document number (DCN) should be created.

·       C: When you revise a document the mentor system adopts the previous authors name, so you need to change it if required. Perhaps we need to consider adding names to the author list on the front page should be.

·       Chair: There are actually some guidelines in the OM.

·       C: Ok, but perhaps the OM could be clarified and updates.

·       Chair: Sure, and I think you have an action item.

·       C: To take authorship of a document, when you add a little bit of text to a document. is not the right thing to do. I took part in the AANI liaison work this week and the behavior of changing the authorship has caused a lot of confusion.

·       C: This has also happened in TGai and TGmc

·       Action: To bring this topic back at the November mid-week plenary.

 

 

a)       If official request – WG officers will generate a response

b)      Do we need a security experts group?

i)        What would this group do that we can’t already do?

ii)       What responsibilities and powers would it have?

iii)     Discussion:

(1)    Perhaps have a mailing list.

(a)    What are the rules about its use?

(b)   Obligations of members of list?

(c)    C: what benefit over existing lists?

(i)      Perhaps use a unique heading/tag

(2)    C: don’t think we need a formal group

iv)     What problem are we trying to solve? 

(1)    Insufficient review of security mechanisms.  So should look for alternative ways of solving this problem.

 

11.   Round Table

a.       Mark H:  wants to focus on MIB patterns.  If you are interested, go to ARC.

b.      Dorothy: has 2 topics queued for the EC rules meeting.  Additional material regarding individual participation.  Action: send link to CAC reflector.

c.       WC SC move to disband REG SC, effective end of meeting.

12.   Discussion topics for CAC2/Sunday

a.       Continuation of security group
