METHOD AND DEVICE FOR SUPPORTING COMMUNICATION VIA RELAY NODE

Abstract

To provide a method and a device for supporting communication via a relay node.SOLUTION: A relay node can receive a WTRU buffer status report (BSR) from a plurality of wireless transmit receive units (WTRU) serviced by the relay node. The WTRU BSR indicates an uplink buffer status at the WTRU. Then, the relay node can transfer the WTRU BSR to a donor evolved node B (DeNB). The relay node can send a relay node BSR to the DeNB. The relay node BSR indicates a relay node uplink buffer status and/or relay node downlink buffer status at the relay node. The relay node can send a radio resource control (RRC) message to the DeNB in order to request radio resource reconfiguration.SELECTED DRAWING: Figure 3
