Re: [STDS-802-16] Regarding Band AMC--Mapping
Title: Samsung Enterprise Portal mySingle
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.

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.
