Hi All: I list out some questions as
follows: (1)
Do we have any other
definition for local forwarding? (2)
Is signalling for
local forwarding establishment required through BS? I would like to discuss on
this. a.
If BS is not
required to take control of the signalling procedure, it is not necessary ? b.
If BS is required to
take control of the signalling procedure, it is necessary ? c.
If BS is
participating without taking the control, it is an option ? (3)
Local forwarding for relay is that it allows
mobiles to communicate with each other via relay(s) without going through the
BS (by Shyy,
DJ) a.
As BS may require a
copy of the data, it is an option to go through the BS, i.e. Relay sends one
copy of data to BS. (4)
Handover issues a.
The case when one of
the two communicating MS changes to be under the control of the Relay that can
perform local forwarding b.
The case when one of
the two communicating MS changes to be out of the control of the Relay that can
perform local forwarding Please comment. Regards, Shoukang From: Shyy, DJ [mailto:djshyy@mitre.org] Hi All: My
understanding of local forwarding for relay is that it allows mobiles to
communicate with each other via relay(s) without going through the BS.
However, the signaling to establish local forwarding communication still needs
to go through the BS. The subsequent data transfer does not need to go
through the BS. From: Zheng
Shoukang [mailto:skzheng@I2R.A-STAR.EDU.SG] Hi
Zhang Xin, Regarding
to local forwarding, I suggest we should define clearly. In my opinion, the
local forwarding is defined as the receiving and forwarding by relay station
(RS) for two communicating mobile stations (HR-MSs) that are under its
own control, without going through the backhaul. Regards, Shoukang From: ZHANG
Xin [mailto:zhangxin@NICT.COM.SG] Dear
802.16n participants, Hearing
no response from the first kick-off email, may I call for questions or
comments regarding the listed contributions from the audience floor? Thank
you very much! Best

Xin [mailto:zhangxin@NICT.COM.SG] Dear 802.16n participants, I would like to initiate an email
discussion on relay operation and forwarding. According to the agenda in our
last teleconference (C802.16n-rg-11/0044r1), document 32r1, 55r1, 38, 24r2, and
37 belongs to these categories. The following topics are
addressed: -
Local source and sink at HR-RS (55r1) -
Alternative connection (38) -
Relay Mechanism (32r1) o
BS-BS communication via relay support o
MS-MS communication via MS in relay mode -
Local Forwarding (24r1) o
RS-initiated local forwarding o
Handover -
Enhanced Local Forwarding for Multicast Service (37) I think there are not too many conflicts among these
contributions, I would like to suggest to consolidate them into sessions of
Relay Operation and Local Forwarding. What are you opinions? Any comments are greatly
appreciated. Thank you! Best Regards, Xin Zhang, PhD NICT |
