METHOD AND APPARATUS FOR SUPPORTING COMMUNICATION VIA RELAY NODE

摘要

PROBLEM TO BE SOLVED: To disclose a method and an apparatus for supporting communication via a relay node.SOLUTION: The relay node can receive from a plurality of wireless transmit/receive units (WTRUs) served by the relay node, buffer status reports (BSRs). The WTRU BSRs indicate uplink buffer status at the WTRUs. The relay node then can forward the WTRU BSRs 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 a relay node downlink buffer status at the relay node. The relay node can send a radio resource control (RRC) message to the DeNB for requesting radio resource reconfiguration.
