Abstract

A method and apparatus for transmitting an indication in a wireless communication system is provided. A relay node (RN) transmits an indication which indicates that the RN is either a fixed relay node or a mobile relay node, and receives initial parameters from an operation, administration, and maintenance (OAM) according on the indication. If the RN is the mobile relay node, the initial parameters includes a list of donor eNodeB (DeNB) cells at a trajectory of the RN.

Claims

1. A method for transmitting, by a relay node (RN), an indication in a wireless communication system, the method comprising:

transmitting an indication which indicates that the RN is either a fixed relay node or a mobile relay node; and

receiving initial parameters from an operation, administration, and maintenance (OAM) according on the indication.

2. The method of claim 1, wherein the initial parameters includes a list of donor eNodeB (DeNB) cells at a trajectory of the RN if the RN is the mobile relay node.

3. The method of claim 2, wherein the RN is deployed at a high-speed train.

4. The method of claim 1, wherein the initial parameters includes a list of donor eNodeB (DeNB) cells if the RN is the fixed relay node.

5. The method of claim 1, further comprising attaching as a user equipment (UE) for initial configuration before transmitting the indication.

6. A relay node (RN) in a wireless communication system, the RN comprising:

a radio frequency (RF) unit for transmitting or receiving a radio signal; and

a processor coupled to the RF unit and configured for;

transmitting an indication which indicates that the RN is either a fixed relay node or a mobile relay node; and

receiving initial parameters from an operation, administration, and maintenance (OAM) according on the indication.

7. The RN of claim 6, wherein the initial parameters includes a list of donor eNodeB (DeNB) cells at a trajectory of the RN if the RN is the mobile relay node.

8. The RN of claim 7, wherein the RN is deployed at a high-speed train.

9. The RN of claim 6, wherein the initial parameters includes a list of donor eNodeB (DeNB) cells if the RN is the fixed relay node.

10. The RN of claim 6, wherein the processor is further configured for attaching as a user equipment (UE) for initial configuration before transmitting the indication.
