Aren't all modes optional in this amendment?
Remove section 10
DAMI and OOK are inefficient.
Sub-clause provides the description of optional MCS modes: OOK and DAMI.
As discussed in previous meetings, OOK/DAMI modes are designed for low complexity and low power consumption.
OOK mode can adopt the simplest envelope detection scheme for low complexity, power consumption and cost implementation.
DAMI is for high data rate applications, and offers low power consumption and complexity.

5. CID’s #9 and #10 (2)
CID#9 presents no new technical arguments.
It is not clear what kind of efficiency CID#10 refers to.
Recommended resolution: Reject comments #9 and #10.

The optional low complexity mode is located in the middle of the SC PHY system design. It is cleaner to move this sub clause to the end of the SC clause.
Move to the end of 12.2 SC clause

in table 100 is not clear what OFDM mode, SC mode, HIS mode, AV mode and OOK mode mean. For example "OOK mode" is not defined anywhere else
Table 100 needs more explanation and it should be compatible with the descriptions on the rest of the document.
144 74 T
It is not exactly clear what OFDM mode, SC mode, HIS mode, AV mode and OOK mode means in table 99. For example, I do not fine "OOK mode" other than this place
This part is newly added this time. Needs more explanation.
OOK mode is defined at sub-clause and Annex D2.
Recommended resolution: Close the comment.

OOK PHY mode is not necessary as the other SC PHY modes cover its usage cases
OOK PHY Option should be removed from the specification. I believe there are other SC PHY modes that are just as inexpensive to build.
147
DAMI PHY mode is not necessary as the other SC PHY modes cover its usage cases
DAMI PHY Option should be removed from the specification.
These comments are related to implementation issue rather than specification.
No new technical argument.
OOK mode is designed for handheld device usages, which requiring simplest envelope detection and ultra low power consumption. OOK is the best option for cost and power sensitive handheld devices.
DAMI mode is designed for higher data rates and portable applications.
Recommended resolution: Reject the comment.

Table 112 T
PNC capable OOK/DAMI dev can only support 25.3Mbps?
Clarification
Table 112 requires the CMS mode to be mandatory for PNC capable OOK/DAMI DEV. This doesn’t mean that PNC capable OOK/DAMI DEV can only support the CMS mode.
Besides the CMS mode, other SC modes are applicable for PNC capable OOK/DAMI DEV.
Mode is defined in Table 11.
Recommended resolution: Close.

Please change the name " low complexity mode", because there is no guarantee of "low complexity" for OOK and DAMI in comparison with phase modulation base PHY mode.
Please use other word such as "non-phase modulation PHY mode".
Recommended resolution: Change title to “Optional OOK and DAMI PHY Modes”
