Dear Jocelyn,
My approach would be to look for coherent
optimized solutions for mobility. I would not preclude any technologies and it
would be possible to produce multiple documents addressing different solutions
and market needs. The attractiveness of the OFDM solution is that it fits in
with current IEEE work and trends toward 4G Cellular networks.
Best Regards,
Mark

Questions
Dear Mark,
Would the physical layer be restricted only to considering OFDM or would it
be open to other promising technologies such as TCMA?
Best Regards,
Jocelyn Chow

Puneet,
Sorry about frogetting to respond to the second question.
Right now the consensus is that the scope includes both overlay on existing
licensed cellular bands and potential new spectrum. The overlay aspects will
obviously have to be able to coexist with existing systems and existing
regs. To the extent that regulators impose technology restrictions on
particular bands these will have to be resolved.

Mark,
Thanks, that's what I had thought, but wanted to confirm that it was the
case.
What about my other question about the FCC issue -- has that been addressed
by the SG yet? I would be interested in hearing what the opinions of the
group are on this subject.

Punit,
The document you are referencing reflects the status at the end of the SG
session. The reference to OFDM and other technologies still needs to be
discussed and resolved.

The Interim Plenary Report for Session #19
(http://grouper.ieee.org/groups/802/16/mobile/docs/80216sgm-02_02.pdf)
does
not mention the use of OFDM for the air interface, whereas earlier
contributions to the SG did so. For those of us who did not get a chance to
attend Session #19, would someone please explain this omission of OFDM.
On a related topic, is the new air interface expected to be an overlay on
existing licensed cellular bands, or will it require new spectrum
allocations? If an overlay, will it not face strong resistance from FCC
and
other regulatory agencies?
