    • It is described a method for transferring data in a downlink direction from a transmitting network (NE) element to a user equipment (UE). The described method comprises (a) sending at least one data packet from the transmitting network element (NE) to a source base station (BS1), (b) receiving the data packet by the source base station (BS1), which is connected to a source relay node (RN1) representing a source access point for the user equipment, (c) caching the data packet by the source base station, (d) handing over the user equipment from the source relay node to a target access point (RN2, BS2, BS1), and (e) transferring the data packet from the source base station via the target access point to the user equipment. It is further described a corresponding method for transferring data in an uplink direction from a user equipment to a receiving network element, wherein the caching is carried out by a target base station (BS2). Furthermore, it is described a source base station (BS1) and a target base station (BS2), which are adapted to carry out respectively one of the above mentioned data transferring methods.
    • 描述了一种从发送网络(NE)元件向用户设备(UE)向下行方向传送数据的方法。 所描述的方法包括:(a)将至少一个数据分组从发送网元发送到源基站(BS1),(b)由源基站(BS1)接收数据分组,该基站连接到 表示用户设备的源接入点的源中继节点(RN1),(c)源基站缓存数据分组,(d)将用户设备从源中继节点移交给目标接入点(RN2 ,BS2,BS1),和(e)经由目标接入点将数据分组从源基站传送到用户设备。 进一步描述了从用户设备向接收网络单元在上行链路方向上传送数据的相应方法,其中,高速缓存由目标基站(BS2)执行。 此外,描述了适于分别执行上述数据传送方法之一的源基站(BS1)和目标基站(BS2)。
