Method for switching working mode on relay network, base station, relay node, and communications system
First Claim
1. A method for switching a working mode on a relay network, the method comprising:
- sending, by a donor eNB (DeNB) a relay node (RN) reconfiguration message to a RN in frequency division duplex (FDD) mode, so that the RN switches from the FDD mode to a half-duplex frequency division duplex (H-FDD) mode;
receiving, by the DeNB, an acknowledgment message sent by the RN in FDD mode;
after receiving the acknowledgment message, verifying, by the DeNB that the RN has already started to switch from the FDD mode to the H-FDD mode according to the RN reconfiguration message and the acknowledgement message;
switching, by the DeNB, from the FDD mode to the H-FDD mode; and
receiving, by the DeNB in H-FDD mode, an RN reconfiguration completion message sent by the RN in H-FDD mode.

Abstract
The present invention provides a method for switching a working mode on a relay network, a base station, a relay node, and a communications system. A donor eNB (DeNB) sends an RN reconfiguration message to a relay node RN in frequency division duplex FDD mode, so that the RN switches from the FDD mode to a half-duplex frequency division duplex H-FDD mode. The DeNB receives an acknowledgment message sent by the RN in FDD mode. When the DeNB verifies, according to the RN reconfiguration message and the acknowledgement message, that the RN has already started to switch from the FDD mode to the H-FDD mode, the DeNB switches from the FDD mode to the H-FDD mode.

6. A method for switching a working mode on a relay network, the method comprising:
-
receiving, by a relay node (RN) in a frequency division duplex (FDD) mode, an RN reconfiguration message sent by a donor eNB (DeNB) in the FDD mode; starting to switch the RN from the FDD mode to a half-duplex frequency division duplex (H-FDD) mode according to the RN reconfiguration message; sending, by the RN in the FDD mode, an acknowledgment message to the DeNB, wherein upon receiving the acknowledgment message the DeNB verifies, according to the RN reconfiguration message and the acknowledgement message, that the RN has already started to switch from the FDD mode to the H-FDD mode, and wherein the DeNB switches from the FDD mode to the H-FDD mode after verifying that the RN has already started to switch from the FDD mode to the H-FDD mode; and sending, by the RN in H-FDD mode, an RN reconfiguration completion message to the DeNB in H-FDD mode. - View Dependent Claims (7)

8. A base station, comprising:
-
a sending unit configured to send, in a frequency division duplex (FDD) mode, a relay node (RN) reconfiguration message to an RN; a receiving unit configured to receive an acknowledgement message sent by the RN in the FDD mode, the acknowledgment message verifying that the RN is switching from the FDD mode to a half-duplex frequency division duplex (H-FDD) mode; and a, configured to switch from the FDD mode to the H-FDD mode after verifying that the RN has already started to switch from the FDD mode to the H-FDD mode, wherein the receiving unit is further configured to receive, in the H-FDD mode, an RN reconfiguration completion message sent by the RN in H-FDD mode. - View Dependent Claims (9, 10, 11)
