    • 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。

    • A method is provided wherein a base station and at least one further base station are assigned to a cooperation area, wherein a user equipment is served by the base station. The method comprises determining, by the base station, whether all user data of the user equipment being required for a precoding coordinated multipoint transmission is received by each of the base station and the at least one further base station, selecting a transmission mode, wherein the transmission mode is based, if all user data of the user equipment being required for a precoding coordinated multipoint transmission is received by each of the base station and the at least one further base station, on precoding coordinated multipoint transmission, or else, on an interference reducing transmission, and configuring, by the base station, the communication channel between the base station and the user equipment based on the selected transmission mode.
    • 提供了一种方法,其中将基站和至少一个另外的基站分配给协作区域,其中用户设备由基站服务。 所述方法包括由所述基站确定所述基站和所述至少一个其他基站中的每一个是否接收到用于预编码协调多点传输所需的所述用户设备的所有用户数据,选择传输模式,其中, 传输模式是基于预编码协调多点传输所需的用户设备的所有用户数据都由基站和至少一个另外的基站中的每个接收,在预编码协调多点传输上,或者在干扰 基站根据所选择的传输模式减少基站和用户设备之间的通信信道的传输,以及配置。
