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, by the RN, the indication which indicates that the RN is either a fixed relay node or a mobile relay node, to an operation, administration, and maintenance (OAM); and

if the indication indicates that the RN is the mobile relay node, and if trajectory of the RN is pre-determined, receiving, by the RN, a list of donor eNodeB (DeNB) cells for the mobile relay node, from the OAM, wherein the DeNB cells for the mobile relay node are cells deployed at the pre-determined trajectory of the RN,

if the indication indicates that the RN is the fixed relay node, receiving, by the RN, a list of DeNB cells for the fixed relay node, from the OAM, wherein the DeNB cells for the fixed relay node are cells deployed at a neighbor of the RN,

wherein the mobile relay node is deployed on a vehicle which moves along the pre-determined trajectory.

2. The method of claim 1, wherein the mobile relay node is deployed on a train.

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

4. 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, that;

controls the RF unit to transmit an indication which indicates that the RN is either a fixed relay node or a mobile relay node, to an operation, administration, and maintenance (OAM); and

if the indication indicates that the RN is the mobile relay node, and if trajectory of the RN is pre-determined, controls the RF unit to receive a list of donor eNodeB (DeNB) cells for the mobile relay node, from the OAM, wherein the DeNB cells for the mobile relay node are cells deployed at the pre-determined trajectory of the RN,

if the indication indicates that the RN is the fixed relay node, controls the RF unit to receive a list of DeNB cells for the fixed relay node, from the OAM, wherein the DeNB cells for the fixed relay node are cells deployed at a neighbor of the RN,

wherein the mobile relay node is deployed on a vehicle which moves along the pre-determined trajectory.

5. The RN of claim 4, wherein the mobile relay node is deployed on a train.

6. The RN of claim 4, wherein the processor further attaches as a user equipment (UE) for initial configuration before transmitting the indication.
