Re: stds-802-16-mac: Paragraph 8.1



Vladimir,

Regarding your note (below) of December 19: Although I agree with 
your intent, I think the layout in the current TG1 draft (IEEE 
802.16.1/D1-2000) works better. Notice that the PHY clause looks like 
this:

  8. PHY Layer
   8.1 Physical layer (PHY) service specification
   8.2 Physical Layer for 10 - 66 GHZ

This keeps the PHY SAP separate from all the specific PHYs, which is, 
I believe, your main point.

Also notice that the outline basically follows the reference diagram 
(Figure 2 - "802.16.1 protocol layering, showing service access 
points") from top to bottom, which is a good logical order. If you 
kept this order but moved the PHY SAP up to the end of the previous 
section, it would end up in the Security Sublayer section, since this 
is where the MAC interfaces with the SAP. That would be a confusing 
place for it.

I think that Glen came up with a good solution and recommend that we 
stick with it.
