Remaining comments addressing the CSS coexisting information ( a)
CID 136 Accept in principle: Stay with the 1% duty cyle but add that “Under certain conditions duty cycle can go up to 10%“
CID 139 Accept in principle. Add more information on this. Reasonable numbers for 11b/g are: 1500 bytes, 50% duty cycle (b:5.5Mbs, g:22Mps)
CID 140 Accept in principle.The analysis between BT and CSS will be revised under the assumption that both systems arw fast hoppers and/or assuming a duty cycle of 50% for BT.
CID 141 Reject, since 11g is addressed in the note at the bottom of  page 4 of a-css-ca-document.pdf.

4. CID 35 Comment: Suggested remedy: Proposed response:
May 2006
CID 35
Comment:
PPDU format For UWB the format is given in octets while for CSS it is given in symbols.Neither one shows the the format on bit level. So it is unclear if all bits are used or where are reserved bits
Suggested remedy:
Show the PPDUs for both PHYs in bit allocation and add a reference to a clause which explains how bits and octets are mapped to symbols.
Proposed response:
ACCEPT in principle. Either add information here or at another place in the document.

5. CID 36 Comment: Suggested remedy: Proposed response:
May 2006
CID 36
Comment:
Bit interleaver: What is the mechanism when there isn't enough data to fill the entire interleaver (at the end of payload)
Suggested remedy:
Add the mechanism and give an example
Proposed response:
ACCEPT IN PRINCIPLE: Add definition for initial state and flushing of the interleaver

6. CID 69 Comment: Suggested remedy:
May 2006
CID 69
Comment:
The specification on how the "DQPSK symbols shall be modulated onto the stream of sub-chirps" is in my opinion vague
Suggested remedy:
none
Proposed response: ACCEPT IN PRINCIPLE. Information on the operation of the interleaver will be added.
