1. Agenda 0047r1
a. Adding AWD editorial process discussion
b. Some concerns about lack of time chair clarified that focused discussions should suffice
and we intend to complete SARM before moving on
c.
Clarification that SRD changes contributions treated at last session if we have time
d. Marianna proposed that hare contribution is appropriate to SARM
e. Agenda approved unanimous consent as 0047r2

Accepted into SARM:
–
Direct Communication Management: Indicates a block which supports HR-MS to
HR-MS direct communication meeting the requirements described in Section 6.1.3.1.
–
HR-MS Forwarding Management: Indicates a block which supports HR-MS Forwarding meeting the requirements described in Section 6.1.3.2.
Regarding the “data forwarding” block in the SARM:
IEEE 80216n-10/0051
•
Discussion on addition of: “or when an HR-MS is present on the path between an HR-MS and an

–
Agreement - Delete rest of text and keep only: Data Forwarding: Indicates a block which
performs forwarding functions.
In other SARM discussions:
Re multi-mode [management] vs. [support]: agreement to use “management”
Agreed to use “path discovery and management” instead of “path management”
c.
Re adding “6.1.3.2” ref to path management: not necessary, agreed to remove, also path
discovery and management instead of mngmt only

65r1 with updates from this morning saved as 65r2 (diagram still to be updated by Samsung /
ETRI) to be adopted into baseline SRD as SARM.
Marianna: 802.16j optional cannot base on it; others comment that we donbt want to define a new
relay for 2009 version. No changes.
All modifications in 61r2 accepted to be incorporated.
0063 agreed Dallas also to be incorporated. Still need a diagram for source and sink.
All to be merged into 38r5.
5. 0038r5merged (on temp) discussed.
a. Marianna: concern that CC cannot replace meetings. It was explained that we are now
just accepting the document as a merge of all previously agreed documents.

11. Ron Murias presents the editorial process adopted for m/p and AWD construction issues
a. Ron will prepare a skeleton table of contents from the existing 802.16 standard including
amendments for us
b. 802.16n is an amendment, e.g. 16m baseline will periodically be updated by all groups so
the groups are synchronized
c.
Discussion of do we need additional section for 802.16n and what’s in it.
Several options re overview section
Chair’s notes:
•
Definition of “overview” – the text that describes 16n new features in one place, and is not
amending existing text, or fitting into existing sections. It includes references to other chapters for
specific modifications.
•
Option 1
–
An overview section for 16n based on16m amendment (Advance Air Interface) is added
at the end of clause 16 as 16.12.
–
An overview section for 16n based on 2009/h/j is added as Clause 17.
–
Option 2a
–
An overview section for 16n is added as clause 17 and applies to both air interfaces.
There would be a 17.1 for advanced air interface, and 17.2 for 2009/h/j. Common features would be described twice, in 17.1 and 17.2.
–
Option 2b
–
An overview section for 16n is added as clause 17 and applies to both air interfaces.
There would be a 17.1 for common features, 17.2 for advanced air interface, and 17.3 for
2009/h/j.

Option 3
Straw poll – in favor: 6
Straw poll – in favor: 2
abstain:
0
None in favor of options 1 or 3
Option 3 used to be “no overview” changed to “abstain”
Strawpoll: 2a in favor 6, 2b in favor 2, abstain 0;
A ToC has been constructed based on 0071 and group discussion. Upload as 0071r1, to be provided to Ron to add the AWD skeleton for basis for CfC for the AWD.
Motion to approve document C80216n-10_0071r1.doc as the baseline AWD Table of Contents,
which will be merged into the overall 802.16 document ToC.

16. Discussion of next steps etc.
-
Level of maturity and voting threshold for AWD and its ToC. Opinions for and
against baselining ToC and requiring 75% for changes. Agreement is that
ToC has same level of maturity as the rest of the AWD which is 50% until
changed.
-
Issuance of CfC for SRD / SARM. Agreement is that anyone is allowed to
submit comments using the commentary data base tool but no CfC.
-
CfC for AWD.
