I agree with Mark. It will be better if we can
consider both 802 and non-802 devices in the study.

Deliverables
Steve,
In general, I agree with all your comments. On the last point, I
think the group needs to discuss Winston's objection. If we create a CB
Band outcome by not considering non 802 devices, it will not be good for
anyone.

Mark,
Comments below. I think it will useful to discuss these further on
tomorrow’s call.
Steve
Steve,
I proposed by
email before the call, discussed on the call and received support for
including:
1.) Collaboration.
If coexistence is understood to include collaboration, then I am
OK.
SJS> My personal opinion
is that coexistence mechanisms could either include collaboration or not,
depending on the technique. So I am fine with collaborative
coexistence techniques.
2.) Use Cases. If
scenarios is understood to mean Use Cases, then I am OK.
SJS> I am not sure if they are the
same or not. I think Use Cases are descriptions of how the networks
are used. I think information is useful in a coexistence
scenario. However, Use Cases can be separate when they focus on the
utility of the network, how it is used, what services are provided,
etc. So if the focus is more on how the networks are used and not
specifically focused on how they coexist, then I would consider this a
separate topic.
3.)
Non 802. If TV White Space Networks is understood to include non 802
devices, then I am OK.
SJS> To me “TV white
space networks” could include both 802 and non-802 network. However,
Winston suggested that it be just 802 networks.
Hope
these clarifications are helpful,

I currently have the following set of potential deliverables on TVWS
coexistence,
· An
IEEE 802.19 document on coexistence scenarios of TV white space
networks
· An
IEEE 802.19 document on coexistence metrics for measuring the level of
coexistence between TV white space networks
· An
IEEE 802.19 document on coexistence mechanisms for enhancing coexistence
between TV white space networks
· An
IEEE 802.19 document on harmonized mechanisms to protect broadcast
incumbents in TV white space
Were
any other possible deliverables proposed on last week’s conference
call?
I
will put together a short straw poll on whether these should be Study Group
deliverables. Before I run the straw poll I just wanted to see if I
should add any other items to the list.
IEEE
802.19 TVWS Coexistence SG,
I have been thinking about the best way to agree on a set of
deliverables. I recommend the following process.
1. Select
a set of possible deliverables – This can be done on next week’s conference
call via email reflector
2. Straw
poll each of the possible deliverables to see if there is support for making
it an actual deliverable – This can be done via email.
I
recommend on next week’s conference call the SG develop the “List of
possible deliverables.” I will not be on the call so Ivan will run the
call.
Here
are my suggested deliverables,
· An
IEEE 802.19 document on coexistence scenarios of TV white space
networks
· An
IEEE 802.19 document on coexistence metrics for measuring the level of
coexistence between TV white space networks
· An
IEEE 802.19 document on coexistence mechanisms for enhancing coexistence
between TV white space networks
On
next week’s call and via email please decide on any other “potential
deliverables.” I would expect all the deliverables to be documents of
one form or another, but someone may have another idea of a good
deliverable. Ivan or Mark can then email me any other potential
deliverables.
After
we have such a list I will run an email straw poll to see how much support
there is for each of these. This is just a straw poll so we need to
think about how much support is needed to decide that the SG wants to
develop such a deliverable. I will recommend that we only develop
deliverables that receive 75% support. If there is less support than
that I would say that development of such a document would be
optional. I don’t want to commit to developing something that has
marginal support.
On tonight’s call we discussed the draft TVWS coexistence
plan,
We will continue that discussion on next week’s conference
call.
If you have comments on the plan you can also make those comments on the
802.19 email reflector. If you are not already on the email reflector
you can join here,
If you have comments on the plan please be specific regarding what changes
you would like to make to the document. You can recommend adding text,
changing text or removing text. Please specify what changes you would
recommend. That would enable others to comment on your
recommended changes.
