I don't know how many asian people will attend the
teleconference, but that time is 24:00 night, so it's not appropriate to me. If it's
shifted to the early morning, or shifted to the afternoon, it'
OK.

Preamble 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
