It is a bit awkward to say that an ‘M2M
group’ will perform some action in the UL. I understand what you intend, but I
think you need to be more thoughtful in the wording. After all, the individual members of this
M2M group have no ability to actively coordinate their action. And at least at
this time a re-entry event is a unicast UL event by an individual 802.16 MS/AMS
peer. My concern is that by stating that an ‘M2M
group’ will perform this behavior you actively invite the creation of some
entirely new concepts that I am not sure you intend. Thanks, From: lei zhou
[mailto:l.zhou@samsung.com] Dear
Jin, Jaesun and all: Thank
you for I
merge your comment together. I summarize some points: 1.
Based on "An M2M device/M2M group may perform network
reentry from idle mode voluntarily for UL transmission. Network also may
request the M2M device/M2M
group to perform network
reentry from idle mode by transmitting a paging message. Ranging access for
both network reentry shall be controlled to avoid access congestion." In
addition, we can further discuss about 4 general issues as follows: For network
trigger, there are two cases, 1)
paging individual M2M device (For M2M device, I think we should follow 16m
procedure of network reentry.) 2)
paging M2M group ( if necessary, we should add procedure for M2M group) For
MS/group trigger, there are two cases, 1) Individual
M2M device (For M2M device, I think we should follow 16m procedure of network
reentry.) 2)
M2M group ( if necessary, we should add procedure for M2M group) 2
For group information, in my understanding some information of group can
help scheduling M2M group when M2M groups access network. PWR RG can
address this issue because issue related on network reentry move to PWR RG. we
can continue to discuss about it more or separate email thread. I
would like to initialize this discussion. 3.
For ranging parameters, there
are still two cases: 1)
For individual M2M device, For
every parameter, we can have further discussion. 2)
For M2M group For
every parameter, we can have further discussion. 4.For
priority access, In my understanding, the concept of priority access should be
related on service/traffic type. After
we unified concept of priority access, we can decide if it is necessary to use
this parameter for schedule M2M devices/groups. Any
comments are welcome! BR Lei ------- Original Message ------- Sender

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. Regards, Kiseon Ryu PWR RG Chair From: Kiseon Ryu
[mailto:kiseon.ryu@LGE.COM] Dear 16p members, The meeting minutes for 2nd 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 2nd PWR RG CC result. The third and final call for PWR RG will be on Thursday,
March 24, 2011, 8AM-10AM Any comment or question will be welcomed. Regards Kiseon Ryu PWR RG Chair
