Abstract

A method and apparatus are provided for connecting Digital Units (DUs) and Radio frequency Units (RUs) of base transceivers in a wireless communication system. The method includes identifying a failed DU of a base transceiver; and linking an RU corresponding to the failed DU to a DU of a different base transceiver which operates normally.

Claims

1. A redundancy apparatus of a base transceiver for connecting Digital Units (DUs) and Radio frequency Units (RUs) in a wireless communication system, the redundancy apparatus comprising:

a connector configured to link the DUs and the RUs; and

a controller configured to control the connector to link an RU corresponding to a failed DU of the base transceiver to a DU of a different base transceiver that normally operates, when the DU of the base transceiver fails.

2. The redundancy apparatus of claim 1, wherein the controller is further configured to receive a signal indicating the failed DU.

3. The redundancy apparatus of claim 2, wherein the signal is received from a higher-layer server.

4. The redundancy apparatus of claim 1, wherein the controller is further configured to receive a signal indicating the different base transceiver.

5. The redundancy apparatus of claim 4, wherein the signal is received from a higher-layer server.

6. The redundancy apparatus of claim 1, wherein the controller is further configured to control the connector to link the DU of the different base transceiver, an RU corresponding to the DU of the different base transceiver, and the RU corresponding to the failed DU.

7. The redundancy apparatus of claim 1, wherein the controller is further configured to duplicate a transmit signal of the DU of the different base transceiver, provide one of the duplicated signals to an RU corresponding to the DU of the different base transceiver, and provide another of the duplicated signals to the RU corresponding to the failed DU.

8. The redundancy apparatus of claim 1, wherein the controller is further configured to combine data channel signals of the RU corresponding to the DU of the different base transceiver and the RU corresponding to the failed DU, and provide the combined signals to the DU of the different base transceiver.

9. The redundancy apparatus of claim 1, wherein the controller is further configured to multiplex control channel signals of the RU corresponding to the DU of the different base transceiver and the RU corresponding to the failed DU, and provide the multiplexed signals to the DU of the different base transceiver.

10. A method for connecting Digital Units (DUs) and Radio frequency Units (RUs) in a wireless communication system, the method comprising:

identifying a failed DU of a base transceiver; and

linking an RU corresponding to the failed DU to a DU of a different base transceiver which operates normally.

11. The method of claim 10, wherein identifying the failed DU of the base transceiver comprises receiving a signal indicating the failed DU.

12. The method of claim 11, wherein the signal is received from a higher-layer server.

13. The method of claim 10, further comprising receiving a signal indicating the DU of the different base transceiver.

14. The method of claim 13, wherein the signal is received from a higher-layer server.

15. The method of claim 10, further comprising linking the DU of the different base transceiver and an RU corresponding to the DU of the different base transceiver.

16. The method of claim 10, further comprising:

generating duplicating a transmit signal of the DU of the different base transceiver;

providing one of the duplicated signals to an RU corresponding to the DU of the different base transceiver; and

providing another of the duplicated signals to the RU corresponding to the failed DU.

17. The method of claim 10, further comprising:

combining data channel signals of an RU corresponding to the DU of the different base transceiver and the RU corresponding to the failed DU; and

providing the combined signal to the DU of the different base transceiver.

18. The method of claim 10, further comprising:

multiplexing control channel signals of an RU corresponding to the DU of the different base transceiver and the RU corresponding to the failed DU; and

providing the multiplexed signal to the DU of the different base transceiver.
