Barber action item from HO Ad-hoc conference call on 6/2/04
I had this action item from the
call:
* Phil - Propose new TLV
flags to support notion of context ID - to convey sectors, frequency
assignment and subnet/prefix/access router ID - by 6/8/04
A 'Sector ID' in the form of a BS MAC ID prefix,
suffix, or additional message advertisement through DCD (and, by implication
through NBR-ADV) has already been proposed by Samsung and I am just going to
refine this idea. Allowing for the bifurcation the existing BS MAC ID,
exactly as proposed by Samsung, seems the best approach since it
encourages fewer changes in other places in the document affecting, among
other things, NBR-ADV messages.
I was planning on borrowing ARID use proposed in
802.21 and advertising it through NBR-ADV. Sticking ARID into DCD seems
overkill. And we don't need ARID in RNG-RSP or SBC-RSP because I am
already going to propose some HO/network re-entry flags in RNG-RSP that will
cover that.
My question concerns the FA (frequency
assignment) element. My question is,
1) wouldn't the sector DCD have the required
information for FA?
Yes, the DCD have the Frequency
param (DL center frequency).
Do we actually require additional MAC level
information for advertising FA?
I think by definition, each sector would have its
own DCD, though for sectored BS using a single frequency/channel assignment,
that DCD would be identical. For sectored BS using different
frequencies/channel assignments in each sector, the DCD would necessarily
be different. And since DCD is imbedded in NBR-ADV, we get appropriate
neighbor advertisement as well.
I think that there is a
problem on advertise the DCD for multiple frequency in a
sector.
Because, In Neighbor
Advertisement message structure, The TLV only got a "DCD_setting" per a sector
(if we agree on the first paragraph- "Sector ID").
So, I think we actually require
additional MAC level information for advertising for a FA_ID per multiple FA
in a sector.
I would appreciate feedback on this item prior to
my scheduled due date for submission.
Thanks,
Phil
