Dear Hongmei,
I completely agree with you that
the spec is not reader friendly. I wish that it will be getting better after
the corrigenda finished.
Regarding to the maintenance comment,
you could refer to the announcement of Roger as following URL.
http://ieee802.org/16/arc/802-16list2/msg02321.html
Maybe there is some indexing
problem. If you have that problem, please track the email reflector about the
indexing issues.
I hope this may help you a little.

I completely understand this after reading you
email, thanks a lot!
A quich question for you (maybe stupid): where/how
can I get the comment file(#244) you mentioned?
I have downloaded the Commentary1.55_session33 from
website, but didn't find this. Maybe I am in wrong way?

Regarding Band AMC--Mapping
Hi, Hongmei
I agree
with you in that the current subchannel definition for AMC permutation is
confusing.
Actually,
6 contiguous bins does not mean 6 bins x 1 symbol block.
It just
means that 6 bins are contiguous in time axis or in frequency axis.
So, there
can be various types of AMC subchannels, for example 1 bin x 6 symbols, 2 bins
x 3 symbols,
3 bins x 2
symbols, etc..
Since a
band consists of 4 bins and a subchannel shall be within one band, 6 bins x 1
symbol is impossible.
There is a
corrigenda comment for description of AMC subchannel structure.
Please see
the comment #244 of corrigenda comment file at the last Seoul meeting.
I hope it
can help you.

Title : Re: [STDS-802-16]
Regarding Band AMC--Mapping
Panyuh,
sorry, but I'm still confused about
this even after your explanation.
As you said, 4 Bins make one Band, and
6 Bins make one subchannel. So doesn't this hint that each AMC
subchannel must exist across Band? (My understanding is: for each
subchannel: 4 bins are from 1st Band, the other 2 bins are from 2nd
Band. Of course, these 6 bins are contiguous.)
In addition,from my understanding,
maybe PUSC DL permutation scheme is an exception case in aspect
of subchannel size, where each subchannel has 24 tones but not 48 tones.
Pls feel free to revise me if my
understanding is not right.

Regarding Band AMC--Mapping
Hi, Varma
and All,
Because
one Band only got 4bins and 4 Bin only can make 32 data subcarriers + 4 pilot
subcarriers. Any subchannel shoud have at least 48 tones(subcarriers),
if we do not restrict the definition of AMC subchannel into
one band. than any AMC subchannel can be exist accross the Band.
So, the
meaning of "AMC subchannel consists
of 6 contiguous bins in a same band"
==> one AMC subchannel should be confined with in the same band. This
definition would help the system exploits the Multi user diversity.
I hope this explanation would help you.

Title : [STDS-802-16] Regarding
Band AMC--Mapping
Hi all,
Section8.4.6.3(P80216-REVd_D5):: Optional permutations for AAS and AMC
subchannels.
A bin was defined as the set of adjacent 9 subcarriers with pilot in
the middle as in Fig:238. But I couldn't understand the meaning of
"A group of 4 rows of bins is called a band. AMC subchannel consists
of 6 contiguous bins in a same band."?????
Can any one help me in this regard.
Regards
varma ivs
