Project Planning Session this week
• Timeslots this week:
– 1st Session: Wednesday, 1pm – 5:30pm (V109)
– 2nd session: Thursday, 3:30 pm – 5:30 pm (V107)
• Objectives for the week
1. Revision Project
•
•
Discuss the submitted contributions
Discuss a possible proposal for the WG
2. Enhancements to 16e
•
Discuss the submitted contributions (2 contributions)
3. Hierarchical Network Study Report :
•
•
7/26/2016

Take a stab at relevant PAR Sections (Scope and Purpose)

1. Revision related discussion
•
Option 1: Regular approach
–
–
–
•
Based on Contribution #39
Consolidation of 16j, 16h and 16m.
Can be done. Procedurally clear.
Option 2: A 2-book approach
– What 2-book approach essentially means is:
• Needs 2 PARs. (Possible in parallel)
• A PAR to create a standard specifying only the Advanced Air interface
• Another PAR to create a standard consisting everything else (of 16-2009, 16j and 16h
amendments (including the amendments to these resulting from the16m amendment))
• The Ongoing TGs (16p, 16n) need to submit PAR changes (if they amend the two standards
mentioned above, they will need to submit two PARs.)
– There is no standard template to split a standard.
• Not trivial to craft it as a revision PAR.
–
–
•
Option 3: Common MAC in a single section
–
–
•
7/26/2016
Need a sub-identifier for each standard (e.g. 802.16.1, .2, …)
Neither of those is a revision PAR.
Followed by a split into 16e, 16m and so on…
Some misunderstandings related to “Common MAC” were clarified and this proposal was dropped.
Consensus: Option 2

2. 16e Enhancement proposals
• 2 contributions (#79 and 80) addressed this topic.
• Only one was presented (#79).
– Contribution #80 was more-or-less identical to #79. So it was skipped.
• The proponent wanted a straw poll.
• Straw Poll
– Are you interested in addressing improvements to WirelessMAN OFDMA?
• Interested: 7
• Not interested: 9

3. Contributions on Hierarchical Network Study Report
• Discussed all the contributions.
• An ad-hoc was created to harmonize the inputs.
• Adopted 008r3 as the “updated” hierarchical network study
report (by consensus). The study report contains:
– Single RAT
•
Interference mitigation (no text), Client cooperation, Effective Spectrum Utilization
– Multi-RAT
•
Enhanced Interworking, Multi-RAT Client Cooperation, Unlicensed Spectrum Usage, Security (almost
unexplored)
• Plan going forward
– Created an ad-hoc group (Lead: Inuk Jung).
– The goal of the ad-hoc is to
•
•
Discuss the issues that could not be agreed upon in Session #71 (MIH, C-AP, O-RAT). Bring a harmonized proposal back to
the PPC
Discuss the scope (as shown in previous slide) and consider/sub-select what is worth following-up. Bring a proposal to the
PPC.
– Conf Calls

Comments on Contribution #39
• As many amendments in 3 years after 2009.
• Not forced to do a revision earlier than that.
• Consolidation may take some time/effort
– Analysis of Figures/Tables/Clauses (possible overlap identification
etc.) ongoing
– IEEE editors to provide a base document (consolidated). That could be
a starting point.
– WG chair asks the IEEE to trigger the consolidation work.
• 30-day deadline does not apply to Maint projects.
– 48-hour notices suffice for Main PARs.
• The group decided to look at the alternatives

Alternatives (How to approach the Revision)
•
Regular approach as suggested in Contribution #39
–
–
•
Consolidation of 16j, 16h and 16m.
Can be done. Procedurally clear. If we go this way, we need to but perhaps now may be a good time
to see if better alternatives are possible.
2 book approach
– Needs 2 PARs. (Possible in parallel)
– There is no standard template to split a standard.
• Not trivial to craft it as a revision PAR.
–
–
Need a sub-identifier for each standard (e.g. 802.16.1, .2, …)
Neither of those is a revision PAR
• What 2-book approach essentially means is that we need to submit two PARs:
–
–
–
–
•
3rd Approach: Common MAC in a single section
–
–
7/26/2016
A PAR to create a standard specifying only the Advanced Air interface
Another PAR to create a standard consisting everything else (of 16-2009, 16j and 16h amendments
(including the amendments to these resulting from the16m amendment))
Both the PARs can be submitted in parallel.
The Ongoing TGs (16p, 16n) need to submit PAR changes (if they amend the two standards metioned
above, they will need to submit two PARs.)
Followed by a split into 16e, 16m and so on…
Some misunderstandings related to “Common MAC” were clarified and this proposal was dropped.

Other Comments related to
Revision/Maintanance
•
Possibility to update annually
–

–
–
7/26/2016
Can be clothed as Amendment or Revision
Annual update as a maint issue (would be trivial)
Putting major amendments would be more complex
Annually or Bi-annually?
The discussion was aborted. Weneed to have more concrete thoughts.

Conclusion
• There was a consensus on following the “two
book” approach.
• Further action:
– PAR discussion proposals are invited for realizing
the two-book approach.

Discussion on HN-related contributions
• Contribution #70
– Discussion
• Is MIH an example of GLL? Or do you wish to replace GLL with MIH
– Replace GLL by MIH.
– Use MIH as an example.
• We can use MIH, ORAT, C-AP, …
– Tightly coupled architecture would not need MIH per se
• If we use tightly coupled approach, do we still need the new layer (GLL)?
• Contribution #71
•
Discussion
• Replace GLL with MIH
• What would be the focus of this group then? Improve MIH?
–
802.1 considers multi-RAT functionality (including multi-radio cooperation)
• Interworking WiMAX-Wi-Fi alsodefined in WMF. What is the relation with MIH?
–
MIH is included in the spec.
• The general concept of inter-MAC communication is defined in 802.1

Discussion on HN-related contributions

– Clean up
– MIH for interworking
• Contribution #73

– Making aware of the MIH option.

Discussion on HN-related contributions
• Contribution #74
– Summary
• Enhanced spectrum utilization across multiple -tiers
• Enhanced interference management techniques enabling maximal spectral reuse
across tiers (e.g. Femto/Macro-tiers) or Multi-RATs
• Seamless mobility of connection flows among Multi-RATs (e.g. data offloading,
handover)
• Enhanced interworking with other RAT (e.g. IEEE802.11).
• Simultaneous use of spectrum across multiple RATs.
• Multi-RAT device collaboration
• Contribution #75

Discussion on Options for Way forward with HN
• Update the Study report
– Ad-hoc to harmonize which ones to adopt in the updated
report.
• Discuss how to eventually develop the PAR
– Scope and Purpose
– Recommendation #1
• Prepare the topics of your interest and share.
• Discuss the topics (create an ad-hoc which can work in the
morning)
• Consensus: The group wanted to do some work in
this meeting to update the study report
7/26/2016
16
Ad-hoc for harmonizing the Inputs
• All the authors + interested people get together, harmonize and
come back by Thursday afternoon with a proposal what should
get in to the HN study report (008r2) as an update (Based on
the 9 contributions that we have).
– Ad-hoc lead: Inuk Jung
• In the scheduled PPC session on Thu afternoon, propose to
adopt the harmonized changes (adoption pending consent of
the PPC) and update the study report
• Later (not a part of the ad-hoc): Consider assigning a group to
work on narrowing the scope by the next meeting.
7/26/2016
17
• Adoption of the ad-hoc output
– Adopt 008r3 as the hierarchical network study
report
• Editorial instructions:
– Remove the items highlighted in yellow from the ad-hoc output
report.
– Replace “GLL” in Figures 7 and 8 with “?”
• Plan for the coming weeks (before the March
meeting)
