Dear Peiying Zhu and all colleague of 
PREAMBLE ad-hoc;
 
In the list of issues raised and 
contributions rejected in Portland meeting, 
my contribution C80216e-04/215r1 "Reference 
Signals for Fast Timing Synchronization in OFDMA" was omitted.
 
This contribution is related to preamble 
synchronization procedure, i.e., related to the issue "Enable fast cell 
search".
I would like to discuss the 
contribution in the ad-hoc.
 
Thank you.
 
Best Regards,
Bin-Chul Ihm

  Ad-Hoc group
  
  Dear all: 
  A preamble ad-hoc group was formed within 802.16e 
  as agreed in Portland meeting. This group is tasked to consolidate all the 
  preamble issues raised and related contributions into a single set of preamble 
  proposals to be submitted during the ballot recirculation. The ad-hoc group 
  will follow the recirculation process, hence must finish harmonized 
  contribution before the Aug. 15th deadline.
   
Given that we 
  have an extremely aggressive timeline, we need to follow some process going 
  forward. The following is my suggestion, your feedback is welcomed.
   
  
    -  Email discussions will use the 
    802-16-MOBILE reflector with prefix [PREAMBLE]. 
 
  
    - Regular conference calls proposed on the 
    following dates (90 min each): 
        Tuesday, 
  July 27 
        Tuesday, Aug  3 
  
        Tuesday, Aug 10 
        
  Friday, Aug 15 (if needed) 
  
Proposed time: 8 AM - 9:30 
  AM US Pacific time (the same time slot used by Jose, seems ok by most 
  people). If I do not hear any objections to these dates/times, I will go ahead 
  and setup call logistics and publish the information by July 26.
  
    - Milestones - I propose the following milestones 
    to keep us on track: 
 
July 19- July 
  27: Discussions on the requirements and issues to be addressed. Discussion on 
  possible harmonization based on the following list of contributions rejected 
  in Portland. Any new contributions must be submitted before this date for the 
  consideration.
  July 27-Aug 3: Consolidate contributions to form 
  one harmonized version 
  Aug 3 - Aug 10: Update the harmonized version 
  before Aug. 15 deadline 
  Aug 15 - Aug 23: respond to reply comments if 
  needed 
  
To start the conversion, here is the list of issues raised and 
  contributions rejected in Portland meeting. 
  Issues raised: 
  
    - Backward compatibility 
    
- Low PAPR 
    
- Enable channel estimation 
    
- Enable fast cell search 
 
Contributions: 
  C80216e-04_115r2  Fast cell search for 
  OFDMA   
C80216e-04_125  Preambles design for OFDMA PHY 
  layer, FFT sizes of 1024,512 and 
  128    
C80216e-04_164r1  
  Preamble sequence for supporting scalable FFT
C80216e-04_188r1  Preamble of scalable OFDMA supporting MIMO 
  system    
C80216e-04_192  Preamble design to 
  enhance MIMO support
  
  
Hope to see a fruitful discussion on this 
  reflector.
