Dear Peiying Zhu, Yigal Leiba,
Jeongheon Kim, and all
As for the Reply Comment of
C80216e-04_215, I sent my response.
Break backward compatibility.
Too much resource used for this single purpose
Need to wait for preamble for BS identification,
frequency offset estimation
==> My contribution is not
to change REVd but to insert new reference signal in some extra band.
And of course, an MSS need to wait
for preamble. To obtain preamble, and MSS must perform symbol timing
synchronization using CP. We make better use of that process only by reading
reference signals. Therefore reference signals can give the information of
preamble's location.
The preambles are sufficient for synchronization.
The contribution does not attempt to prove otherwise.
==> For synchronization, an MSS
must obtain preamble. Reference signals give
the information of remained time to preamble. So an MSS can reduce the
procesdure for obtaining preamble by not scanning during the time.
The effect is represented in revised
contribution.
Defined signals for fast synchronization from
different cells cannot be distinguished.
Also the signals cannot be demodulated before
timing synchronization.
è
==> If an MSS synchronize with a BS, it need cell information.
But reference signals are not need
to distinguish between different cells. Because reference signals are used to inform preamble's location and
preamble has information for cell distinction.
And of course, the signals cannot be demodulated before timing
synchronization. After timing synchronization using
CP, an MSS can find preamble's
location by using the signals.
Please
see my revised contribution.
See you
in Portland.
Best

Thanks,
