Subject: [STDS-802-16-MOBILE] [Handoff]
Minutes from 6/17 telecon
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.
8 . 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.
