HI,
In 802.16REVd/D5,page503,Table 266,
In 802.16e/D4,page111,Table 266a,
I can not see how to decode the UL_MAP by
SS.
I think DLFP in OFDMA PHY should also contain the
UL_MAP information(such as modulaiton/code/length)
except for DL_MAP. otherwise, how to decode
the UL_MAP by SS? and sometime DLFP may also contain the DCD/UCD etc.
information(such as modulaiton/code/length) .
Am I right?

Question about IDCell from the preamble
Hi, Sriram Mudulodu,
I'm sorry I don't understand your reply
exactly.
What's mean 'interference
averaging'?
I think you say IDcell from preamble is used for
doing permutations based on IDcell for data, right?
IDcell used for
pilot modulation and IDcell used permutations for data are
different.
IDcell info
from the preamble is used for pilot modulation and IDCell used permutations for data is
default zero at first.
Below, there is Yigal's answer to my
questions.
========================================================================================================
In REVd/D5,
p. 567 "In the first PUSC zone of the downlink (first
downlink zone) the default used IDcell is 0."
p.526 "The downlink frame
shall start in PUSC mode with IDcell = 0 and no transmit diversity."
1.
What is the first PUSC zone? Does that include FCH,
DL/UL-MAP?
>>> Yes, it includes FCH and DL-MAP
2. Why
IDcell = 0 in the first PUSC zone?
>>> To facilitate operation
with sector reuse <=1 by ensuring that PUSC zone are orthogonal
3.
If answer of question 1 is "yes", where or when will IDcell from preamble be
used?
>>> IDCell from the preamble is use on the first PUSC zone
pilot
modulation
====================================================================
Please see it,
Thanks,
Best Regards,
