Dear Raja Banerjea,
I have questions.
1. Common preamble helps only handover or scanning? In
Table 1 MSS processing flow, MSS does not use the common preamblewhen power
on.
2. I think that the common preamble can be
introduced on the synchronized cell deployment and the locations of the common
preambles are same. If not, I think the common preambles from several
cells will be interference each other. In this case, MSS knows already the
symbol timing and coarse position of the legacy preamble of other cells.
3. In Table 1, does MSS searching common
preamble and legacy preamble of other BSs communicate with the
anchor BS ? If yes, MSS can communicate with the anchor BS while detecting
other BSs? Otherwise, I think MSS shall indicate to anchor BS that it is in
searching mode as if in scanning such that anchor BS halts
communication with that MSS momentarily.
Best Regards,
Bin-Chul Ihm

Preamble Ad-Hoc group CC age nda (followup)
Dear
Preamble Adhoc members,
Based on the conference call today there
was 3 issues raised with respect to contribution
To harmonize the contribution we need to sort
the following issues.
1.
Common preamble repetition duration: This address how often the common
preamble is repeated. Its a trade off
between overhead and initial network entry latency.
Assuming a brute force correlation approach a repetition
interval
of 5
frames gives the same performance as that obtained using the legacy
preamble.
2.
Location of common preamble in Frame: As was suggested during the CC it would
be advantageous to have the common preamble
right after the DLMAP.
3.
Group vs. Cellid: We could use Group ID if it is already defined. I am a bit
unclear about its usage though.
Further comments are welcome.
Regards,
-Raja
Hi
Peiying,
I have uploaded a
contribution
This is similar to "Preambe_adhoc_strcuture_v01"
.
I would like
to discuss this during the preamble adhoc too. Maybe we could discuss it
after Agenda item 1.
Thanks,
-Raja
