IP policy
A SC is covered by the WG IP policy announcements.
Even though we don’t have to read the policy to SC attendees, all attendees are reminded that the policies are in effect and apply to SC sessions.

8. Discussion Topic Ground Rules
Nov 2008
Discussion Topic Ground Rules
We are exploring -
Small group, open, honest dialog
Session is not oriented toward being a tutorial,
Participation requires familiarity with 2007 contents.

Background material: Session notes
Notes are points informally captured during SC discussions - they are not minutes.

14. Nov 2008
Notes: Tues Am 1
How much complexity in diagrams considering the goals?
Tentative Proposal: 5-7 “blocks” on a diagram page; 2 levels - 1 top, 1 of drill down; approx one page text per diagram page.
Seemed a good 1st cut goal
Don’t want clause references to drive explanatory level of detail.
2007 vs doc target shift – implications
We still agree 2007 is right target doc; diagrams to date are 1999 async data centric; more work to do for 2007.

15. Notes Tues AM1 Scope of MAC arc doc functionality
Nov 2008
Notes Tues AM1
Scope of MAC arc doc functionality
Probable 2 categories
Included functionality
Done and in doc
Work still to be done in doc
Ignored within doc
Not felt to be important by SC participants for goals
Generally considered obsolete
Low ROI on effort required to include

16. Notes Tues AM1 Driving message sequences
Nov 2008
Notes Tues AM1
Driving message sequences
A Subset of 1999 was initial set
Were items left out ok to continue to ignore?
Or do we need to include some?
Included to date:
Basic async data slow
Leaving out:
PCF – supplanted by TGe in 2007
Orig PHY related control stuff (FH, DS, IR phys, 1997 regulatory stuff).
What of (Delta ) needs to be added?
Which big chucks of functionality?
Driving sequences to use?
Look ahead exercise (to be done later)
Diagrams “mostly ok” for post 2007 active TG impacts?
David Bagby, Calypso Ventures, Inc.

17. Notes Tues AM1 Misc to-do Enhance intro text in doc Nov 2008
Purpose explanation
Useful framework to understand/discuss changes proposed by Task Groups
Intro to overall mac functionality before dive into standard itself

18. Thurs AM2 notes Driving sequences to try to get (2007-1999) impacts
Nov 2008
Thurs AM2 notes
Driving sequences to try to get ( ) impacts
Probable useful order for exercise?
Simple data missing ack
Finish Data flows cases, missing ack cases
Power saving impacts
Security
WEP
TGi
QOS sequences
Queuing in common
One or both schedulers?
EDCA 1st then HCCA
TGh
(management frame sequences => time bounds handled in what block(s))
PHY control (rf pwr etc)

19. Thurs AM2 notes MIB variable mess Nov 2008
Temporal relation of mib value change vs. action
Control
Internal interfaces
External interfaces

20. Nov 2008
Thurs AM2 notes
Discussion: initial consideration of QOS addition to diagrams.
Re QOS impacts – where is logical queuing put for retry? Block 3 or 5?
Many or one thing at a time from 3 to 5?
Does 5 have any data store?
Is there flow control between 3/5?
What happens if we think of QOS as multiple instances of some part (maybe all) of the top level diagram?
Is it a virtual STA? (collisions happen at the common medium).
Prob less than the “sta”… Partition by state for medium access? (where is that in current diagram?)
