METHOD, ENODE B, RELAY NODE AND COMMUNICATION SYSTEM FOR SWITCHING OPERATION MODE IN RELAY NETWORK

摘要

The present invention provides a method, an eNode B, a relay node and a communication system for switching operation mode in a relay network. The method for switching operation mode includes: a Donor eNode B DeNB transmitting to a Relay Node RN, in Frequency Division Duplex FDD mode, an RN Reconfiguration message which is for the RN to switch from FDD mode to half-duplex H-FDD mode; the DeNB receiving an Acknowledgement message which is transmitted in FDD mode from the RN; and the DeNB switching from FDD mode to H-FDD mode when the DeNB makes sure according to the RN reconfiguration message and the acknowledgement message that the RN starts switching from FDD mode to H-FDD mode. The present invention ensures that the DeNB and the RN respectively switch operation mode from FDD to H-FDD at proper moment, thus accomplishes the purpose that the RN accesses the relay network correctly and communicates with the DeNB normally.
