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
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.
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.
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!
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
- 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!
