Baruch, all,

Here my answers to your questions:

1) That's our intention.
Even though the mesh mode is and shall be optional one it should be enough
to
implement a mesh mode compliant device to be standard compliant. How to do
that? A simple solution would be to list all the messages a mesh compliant
device
has to "understand" and all the rest are optional ones. As the result we
would have
slightly different lists of messages that apply to PMP and mesh modes. Hope
this
is okay.

2) In the current document we have described all the required information
that is
needed by a SS to "enter" a network. Here network entry actually just means
that
a node is synchronized to the network and can transmit some very limited set
of
management frames to e.g. register to the network.
The 802.16ab-01/01r2 document defines both MSH-NCFG and MSH-NENT messages
as well as the details of their transmission timing. All that information
allows one
to implement a SS that may enter a network and start procedures related to
registration and authentication. At this stage, a SS is not capable of
perform any
real scheduled transmissions. For that we may have to have an additional
functionality
standardized.
One possibility is to standardize a downloading mechanism that could be used
to
download "networking algorithms" you ask for from a neighboring SS or from
the
BS. No real difference in these two options, the former is somewhat better
from radio
perspective while the latter doesn't mandate all the SSs to have the
"uploading"
functionality.
Any comments on this?

Best Regards,
     Mika

Hi Mika,

There are two issues that remain  open regarding the MESH Mode.

                  1)     If an equipment implement ONLY the MESH mode, is it
standard comply.
                  2)     What is the mechanism in which a SS can enter a
network operating in the MESH mode without having the networking algorithms,
which are not includes in the document.

I believe that these two issues need to be addressed in the document.

Regards

Baruch
