[STDS-802-16] [802.16p][DEV RG] Discussion on Group Resource Allocation

[차재선 <jscha@etri.re.kr>]

Dear all

 

I'm Jaesun from ETRI.

 

According to the discussion during the second DEV CC, I would like to initiate discussion on group resource allocation. I have uploaded a new version (C802.16p-rg-11/0013r3).

 

Let me summarize the key point of our contribution.

 

We think that the group resource allocation scheme defined in 16m can be reused for M2M devices. But, our concern is about grouping criteria and the number of Group ID. In 16m, up to 32 AMSs can be grouped into a single group based on MIMO mode and HARQ burst size. Of course, the same criteria can be applied for M2M devices. But, we can expect more efficiency if M2M devices which belong to the same subscriber are grouped into the same group because traffic patterns of M2M devices which belong to the same subscriber are very similar. That's why we propose to consider a subscriber as one of criteria for grouping.

 

In addition, if we consider a subscriber as one of criteria for grouping, then the current number of group IDs may not be enough. In 16m, up to 127 group IDs can be used to identify a group for group resource allocation and this number is decided based on the possible combination of MIMO mode and HARQ burst size. So, If we consider a subscriber as one of criteria for grouping, then more group IDs are needed for indentifying groups which consist of M2M devices.

 

Since there are no other contributions related with group resource allocation, I would like to discuss group resource allocation for 16p with our contribution (C0013r3).

 

If you have any comments or questions on the contribution, please share your opinion with us.

 

Thank you.

Subject: [STDS-802-16] [802.16p][DEV-RG] Conference Call-2 minutes

Dear 16p members,

The 2^nd 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.
