Almost finished with my 'flags' contribution.  Will get it out today.  It includes support for HMAC Tuple in RNG-REQ.
 
Thanks,
Phil.

Minutes from the conf call:

1. Discussion on harmonized contribution C802.16e-04_87r2 (please review this in advance of the call)  

- We got general agreement on the following:

- Makes sense to include HMAC tuple in RNG-REQ (to be confirmed with security adhoc group)

- Use current SBC profile - if MSS has information it should prefer that to a minimum/ default profile

- Indicating flags in RNG-REQ/RSP as proposed by Phil may be a good idea. BSHO-REQ should also indicate levels. 

Main issues to resolve:

- UL concatenation of messages Samsung concern - UL large packet size at low coding rates is inefficient. Runcom claims that this is more efficient for lower levels.

- Define discrete levels for HO context transfers / sharing versus arbitrary levels based on flags. or not.

2. Closure on definitions of Base station ID, Operator ID, Sector ID and Frequency Assignment (FA) ID - including relationship, hierarchy etc.  

- 2 new 8-bit fields to be added to DCD-Map and NBR-ADV to represent Sector ID and Channel Number (preferred over FA ID)

- Also we decided to make Sector ID = Preamble Index 

Drafting team will ensure backward compatibility is preserved

3. Closure on harmonization of 105_Inter-sector HO and 04/58  

 Jung-won will work on an update in time for the drafting section. He will send out a short email summarizing how these contribs will be harmonized.

3. SHO harmonization with fast switching BS HO and hybrid approach
 - Samsung was supposed to upload a contribution but have'nt seen that yet
 - No harmonized contribution yet (SHO / fast switching BS HO / hybrid)  

- Mary and Mo-Han believe it possible to develop a common MAC contribution supporting both FBSS and SHO. Both solutions are being pursued for harmonization and both solutions will be optional. As part of the harmonization, the group will look into support for dynamic selection between FBSS and SHO (in deployments where both are supported in a deployment) - perhaps the anchor BS will make such decisions.

The group has not had time to review the 2 PHY contributions from Nortel and Samsung. Also a harmonized MAC contribution requires more work; email discussions will continue to make progress prior to the 6/25 deadline. Meanwhile, during the drafting session, the group will make an attempt to write up non PHY specific text and circulate to the group for feedback.

4. Any specific recommendations for changes / additions to DCD map to optimize / support HO  

Please email specific suggestions to Prakash so the drafting team can track and ensure they get addressed.

5. Scanning optimizations. Contributions to discuss:
- Simplified scanning procedure  

There was a lot of debate on what does the BW parameter conveys? Contribution needs further discussion to be driven by Mo-Han.

Kamran will send out a summary of the proposal he discussed during the call.

Prakash will pull out relevant text from .11k for group review.

Samsung also suggested that the group review contribution 57 in this context.

- A method of scanning neighbor BSs periodically-rev  2   

This contribution needs more review and discussion on the mailing list before we can declare consensus or reject.

- Method to reduce number of scanning  

 There was a comment that the contribution does not address multiple frequency assignment. More discussion to follow on the mailing list.

6. Decision on ARID vs. prefix/subnet ID for optimizing IP connection establishment (use Ronny Kim's contribution 90r2 as basis) 

Chunjae Song - Samsung to upload new contribution; will attempt to converge over the mailing list. SKT, LG and Samsung.

Itzik supports 68r2 (Phil might agree with that as well).

Branislav has since raised a concern that the contribution does not adequately address all scenarios. Request to provide some text to help drive discussion.

7. Idle mode related contributions:
04/66r1 - Location management for supporting Idle mode
04/108
04/28r1
04/105 - Complementing Idle Mode handover operations  

Discussions to continue on the reflector. 

. Other contributions:
- Overhead reduction for initial ranging
- Ping pong criteria (do we have proposed text?) 04/55r3
- MSS release after completing initial network entry
- 04/48
- 04/57
- 04/76r2
- 04/61
- 04/65
- 04/50r1
- 04/51r1

We ran out of time. More email discussions needed.

* Any contributions addressing different FFT size between sectors (so far we have none)  

Only applicable for inter-operator HO scenarios, so this will be dropped for now.

* Any contributions related to informative text additions

None.

* Any contributions related to clarifications / changes to SDLs

None.
