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
