Re: [STDS-802-16] Seeking Contributions regarding IMT-Advanced Requirements
Roger,
Thank you so much for your clarifications. I agree that contributions to
"WP8f" must be "tuned" to the ITU-R IMT-Advanced project's purpose. I
was concerned that TGm would not have an opportunity to harmonize (in a
F2F meeting) some key "16m" requirements. As you have suggested, this
goal may be achieved offline with a bit of goodwill and cooperative
spirit by the contributing members.
Best regards,

Dan,
Personally, I think that the timeline for alignment within 802.16 is
pretty good.
An 802.16 document towards an 8F contribution on this topic should
reflect the technical requirements for P802.16m. However, the documents
won't be identical. For instance, I expect that some details from the
P802.16m document are going to be specific to that project and not of
interest to 8F. Also, the formatting and tone of the two documents is
going to be very different. Therefore, I think we need to think about
two very different documents, though we ought to maintain consistency.
I think that the March 8 deadline for contributions on the 8F proposal
will give people time to draft some material, making use of their own
views of what should be in the contribution. They can, of course, refine
their views based on (a) the contributions due on Feb
23 in response to IEEE 802.16m-07/004r1; and (b) the output of the TGm
Requirements drafting group on March 5.
The 802.16 WG will have a chance to review both sets of material at
Session #48. We need to work out when we will get it to 802.18. As to
harmonization within 802.18, that's another matter.

It will be possible to include ideas from that document in our draft
material towards an 8F contribution, though we will have less time for
harmonization.

I agree. I don't think that 802's expertise is relevant to the entirety
of 8F's requirements activity. However, on certain issues, I believe
that 8F would value 802's technical insights. For instance, my
presumption is that 8F would want to set minimum technical requirements
so as to be challenging but feasible. Here the views of a technical body
like 802 would be of value.
Also, I wouldn't consider an P802.16m requirements document to be
permanent, even if we reached a consensus in March. I believe that we
need to maintain a technical requirements document as a living document
that can change as times change. For example, it would be appropriate to
reconsider the P802.16m view of requirements once the 8F view becomes
more clear,
