Dear all,

I updated the consolidated contribution as C80216p-rg-11_0032r5 to include the proposed text in C80216p-rg-11_0035 (submitted by Jaesun) and the updated text in C80216p-rg-11_0028r1.

Subject: [STDS-802-16] [802.16p][PWR RG] Meeting Minutes of PWR RG CC#2

Dear 16p members,

The meeting minutes for 2^nd PWR RG CC are as follows:

1. Email discussion summary (80216p-rg-11_0041) was reviewed.

2. Harmonized contribution on Idle Mode Operation (C80216p-rg-11_0036r1) was reviewed.

A. Members agreed to the blue text in the contribution as the consensus text

B. Consensus text will be included without bracket in the updated document for consolidated contribution.

3. Harmonized contribution on NE#2 (C80216p-rg-11_0028r1) and NE#1(C80216p-rg-11_0040) were reviewed.

A. Some members raised concern on NE#2 (C80216p-rg-11_0028r1) as follow.

i. If BS does not know when M2M devices perform network re-entry, static and periodic assignment of dedicated ranging resource can increase resource overhead.

B. Some members raised concern on NE#1(C80216p-rg-11_0040) as follows.

i. If the M2M device receives multicast traffic indication in paging message, it does not have to perform network re-entry to receive the multicast traffic. In this case, access restriction has no meaning.

ii. Ranging abort in RNG-ACK message can be used for this kind of access restriction.

4. Key issues for NE#1 and NE#2 were discussed.

A. Some members shared their views on the issue of the priority based ranging parameter differentiation

i. We need to analyze the gain of priority based ranging parameter differentiation.

ii. In the case of predictable re-entry of M2M devices, ranging parameter can be different to M2M devices/groups to distribute the re-entry load.

iii. Ranging parameter means not only ranging parameter values (e.g., opportunity window, backoff window, etc.) but also assignment of dedicate ranging resource to M2M devices/groups.

B. Members agreed to the high level text for NE#1 and NE#2 below and it will be included without bracket in the updated document.

i. Ranging parameters may be different to M2M devices or M2M groups.

C. Through the email discussion, detailed text will be discussed further.

5. DC#1 (C80216p-rg-11_0037) were reviewed.

A. Some members raised concern on the gain of device collaboration.

I updated the consolidated contribution C80216p-rg-11_0032r4 based on the 2^nd PWR RG CC result.

The third and final call for PWR RG will be on Thursday, March 24, 2011, 8AM-10AM US Central Time.

Any comment or question will be welcomed.

Regards
