The diagrams were intended to be complementary to each other. Maybe
we need
to add some text to the document to explain how the two diagrams should
be
interpreted. I can work on some text and propose it to the group if
folks
agree that this would help make the section clearer. If it is
necessary to
add management interfaces to the first of the two diagrams, I would
propose
to do so without too much detail.
I would suggest that we add a simple management interface to the first
diagram. I agree that a great deal of detail at this point isn't
necessary. As you mention, a little bit of text to indicate that
management aspects are included in a generic way would be useful
too.
Regarding the diagram that Marianna
proposes, I don't believe that the "CS
PHY" (meaning Convergence Sublayer PHY) that lies between the MAC
and PHY
represents greater clarity about the interface between the MAC and
PHY.
Perhaps we should include the interface, and as in 802.11, simply call
this the "PHY-SAP" (see figure 11 of 802.11-1999 (Reaff
2003)).
I see elsewhere (message forwarded to the list by Joanne) that Marianna
comments that the term CS-PHY this is to support multiple PHY
Layers. Using the term PHY_SAP gets at the need for clean
definition, but doesn't require (or preclude) multiple PHYs.
The topic of multiple PHYs is an item that we started to discuss during
last week's meeting, but was deferred by Khurram (as I remember) to
e-mail. We should discuss this separately. Certainly if we as
a group want to include support for multiple PHY, it is simpler to do
this from the beginning, as noted elsewhere. For a technology
proposal should this extra flexibility be considered a positive over
those without multiple PHY? There are lots of licensed bands below
3.5 Ghz, and the flexibility to choose a PHY technology could be
attractive in certain situations.
Best regards,
Jim
