    摘要: This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency.

    摘要: This invention extends the coverage and improves the capacity of wireless communication networks using relay nodes. The relay nodes are wirelessly connected to the base station. The base station uses the same radio access technology for a link between the base station and user equipment and between the base station and the relay node. The relay node uses the same radio access technology for a link between the base station and the relay node and between the relay node and the user equipment. The relay node supports at least a Physical Layer (PHY), a Medium Access Control (MAC) sub-layer and a Radio Link Control (RLC) sub-layer protocol.
