Dear Jaesun,
Thanks for initiating issue discussion on group resource allocation for M2M. After reviewing your proposal, I’d like to ask two questions for further understanding.
First, I agree it would be helpful to introduce new grouping criteria on M2M subscriber because probably there will be similar traffic patterns and applications to be supported among M2M devices. In addition, if we agree on that criteria, the existing number of group IDs may not be enough as you mentioned. Then, are you considering M2M devices shall be used only with the new group ID range (129-TBD in your proposal) or they can be still included within the existing group IDs, too?
Second, assuming new grouping criteria on M2M subscriber, what is your consideration on addition/deletion per AMS flow from a certain group? Is it still applied based on the existing mechanism (i.e. using group configuration MAC control message, etc)?
Thank you.
Best regards,
Jinsoo

Dear 16p members,
The 2nd DEV RG conference call was held yesterday, Feb 15, 2011 between 6PM-7:30PM US Central Time.
The meeting minutes are as follows:
1. Email discussion summary (C802.16p-rg-11/0039) was reviewed.
2. Harmonized contribution on Multicast Transmission for M2M devices (C802.16p-4g-11/0038) was reviewed
a. Members expressed concern on the following sentence that it precluded feedback
“ When an M2M device receives the multicast traffic indication through the paging message during its paging listening interval, the M2M device shall start receiving the DL multicast data without the idle mode termination.”
It was agreed to insert a brace in the last part of the sentence.
“When an M2M device receives the multicast traffic indication through the paging message during its paging listening interval, [the M2M device shall start receiving the DL multicast data without the idle mode termination].”
b. Mr. Jeongki Kim (LGE) to continue harmonization and present updated text by next conference call.
3. Contributions C0016, C0022, C0023, C0024, C0025 were presented. But they are dependent on whether the group agrees to support a large number of devices. So, the contributors expressed a desire to revisit these contributions once a decision has been made on the support of large number of devices.
4. Contribution C0013 on grouping mechanism for group resource allocation was presented.
a. Members to continue discussion on the need for additional group ID ranges for GRA to support M2M devices. Mr. Jaesun Cha (ETRI) will coordinate this discussion.
5. Contribution C0028 on supporting large number of devices was presented
a. Members to discuss if rank deficient super-imposed transmission is necessary to be supported for M2M. Mr. Jia-Hao Wu (ITRI) will coordinate this discussion.
6. Contributions C0017, C0020, C0028 will be discussed in the PWR RG.
7. Open discussion on the number of devices to support
a. Some members expressed reservation on the number of active users exceeding the current addressing capability of 16m while other members expressed the view that the application space would be too big to rule out such a possibility with M2M devices.
b. Discussions to continue on email.
The third and final call for DEV RG will be on Tuesday, March 22, 2011, 6PM-8PM US Central Time.
If you have any questions/remarks on the minutes, please do not hesitate to contact us.
