    • It is described a method for transferring data in a downlink direction from a transmitting network element to a user equipment. The described method includes (a) sending at least one data packet from the transmitting network element to a source base station, (b) receiving the data packet by the source base station, which is connected to a source relay node 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, 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. Furthermore, it is described a source base station and a target base station, which are adapted to carry out respectively one of the above mentioned data transferring methods.
    • 描述了一种用于在下行链路方向上将数据从发送网络元件传送到用户设备的方法。 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,(b)由源基站接收数据分组,源基站连接到表示源接入点的源中继节点 对于所述用户设备,(c)由所述源基站缓存所述数据分组,(d)将所述用户设备从所述源中继节点切换到目标接入点,以及(e)将所述数据分组从所述源基站 通过目标接入点到用户设备。 进一步描述了用于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和目标基站。
