Related subclause
Subclause 4.2 page 5 line 8
Comment
An FFD in a TMCTP can be a PAN coordinator or an SPC or merely a member of the network.
Proposed change from commenter
Change "operates as both the PAN coordinator and the super PAN coordinator (SPC)" to "can operate as a PAN coordinator or an SPC or merely a member of the network".

4. Proposed resolution of CID 35 (2)
Reject
The sentence means that at least one FFD among multiple FFDs must be a PAN coordinator and an SPC in the TMCTP.

5. Proposed resolution of CID 36 (1)
Related subclause
Subclause page 5 line 19
Comment
The channel can be the same based on the coordinator geographic location. The sentence need to be modify.
Proposed change from commenter
Change the sentence to "Each PAN coordinator uses a channel allocated by the SPC"

6. Proposed resolution of CID 36 (2)
Accept in principle
Change to "Each PAN coordinator uses a different WPAN channel allocated by the SPC."

7. Proposed resolution of CID 43 (1)
Related subclause
Subclause page 6 line 7
Comment
How can the format of the TMCTP superframe be defined by the SPC?.
Proposed change from commenter
Add some words to describe a mechanism for the SPC to define the format.

8. Proposed resolution of CID 43 (2)
Accept In Principle
Change “The format of the TMCTP superframe is defined by the SPC ” to “The format of the TMCTP superframe is defined by the SPC which sends an enhanced beacon containing a TMCTP Specification IE, as in ”

9. Proposed resolution of CID 45 (1)
Related subclause
Subclause page 6 line 11
Comment
TMCTP-parent PAN coordinator can have multiple TMCTP-child PAN coordinators.
Proposed change from commenter
Change "between the TMCTP-parent PAN coordinator and the TMCTP-child PAN coordinator" to "between a TMCTP-parent PAN coordinator and one of its TMCTP-child PAN coordinator(s)"..

10. Proposed resolution of CID 45 (2)
Accept.

11. Proposed resolution of CID 61 (1)
Related subclause
Subclause page 9 line 7
Comment
Why is TMCTP unique to TVWS operation?
Proposed change from commenter
n/a

12. Proposed resolution of CID 61 (2)
Accept in Principle
Delete "For TVWS operation," and change "when ~~" to "When ~~".
TMCTP concepts can be applied to other WPAN networks.

13. Proposed resolution of CID 62 (1)
Related subclause
Subclause page 9 line 15
Comment
Does the BOP exist if there is no CFP? If so clarify the language so that we know where it would be.
Proposed change from commenter
Either add "The BOP requires the CFP be present' or add "when there is no CFP the BOP shall follow the CAP" depending on what is intended.

14. Proposed resolution of CID 62 (2)
Accept
Add “When there is no CFP, the BOP shall follow the CAP.“ after the first sentence starting “When present, …”.

15. Proposed resolution of CID 64 (1)
Related subclause
Subclause page 9 line 19
Comment
Need to refine the first phrase.
Proposed change from commenter
Change "BOP slots" to " A fixed number of BOP slots".

16. Proposed resolution of CID 64 (2)
Accept in Principle
Change "BOP slots" to "DBSs in the BOP“.

17. Proposed resolution of CID 66 (1)
Related subclause
Subclause page 9 line 23
Comment
"No beacon transmissions within the BOP shall use a CSMA-CA mechanism to access the dedicated channel" is awkward English and an unerifiable "shall". Yes this language was borrowed form but it's not correct.
Proposed change from commenter
Change to "CSMA is not required for beacon transmissions in the BOP".

18. Proposed resolution of CID 66 (2)
Accept
Change as the commenter proposed.

19. Proposed resolution of CID 69 (1)
Related subclause
Subclause page 9 line 26
Comment
Need to account for the cases where aTurnaroundTime is larger than the IFS time.
Proposed change from commenter
Insert instructions to the editor to modify the first paragraph of as follows: "The MAC sublayer needs a finite amount of time to process data received by the PHY. To allow for this, two successive frames transmitted from a device shall be separated by at least an IFS period; if the first transmission requires an acknowledgment, the separation between the acknowledgment frame and the second transmission shall be at least the IFS period or aTurnaroundTime, whichever is greater. The length of the IFS period is dependent on the size of the frame that has just been transmitted. Frames (i.e., MPDUs) of up to aMaxSIFSFrameSize shall be followed by a short interfame space (SIFS) period of a duration of at least macSIFSPeriod. Frames (i.e., MPDUs) with lengths greater than aMaxSIFSFrameSize shall be followed by a long interframe spacing (LIFS) period of a duration of at least macLIFSPeriod. These concepts are illustrated in Figure 10." Insert instructions to the editor to modify Figure 10 to show that for the Acknolwedged transmission, the LIFS becomes max(LIFS, aTurnaroundTime)
