    • 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.

    • User equipments UEs send their buffer status reports and data to a relay node RN. The RN stores the data in actual buffers per radio bearer group RBG, and stores the UEs buffer occupancies in virtual buffers per RBG. The RN then sends its own status report to the controlling eNBr with the actual buffer occupancy and information about the virtual buffer occupancy. This enables the eNBr to know in advance the volume of data incoming to the RN's actual buffers, as well as the current occupancy of those buffers, so as to better allocate radio resources. Further, the RN can take soundings of the uplink channels between UEs and the RN, which are then aggregated across the RBRs and sent to the eNBr as a special UL CQI report. The eNBr is thereby enabled to anticipate how soon the data in the UE buffers will appear in the RN's actual buffers (from the additional information of average UL CQI info and virtual buffer status), and thus better allocate the RBRs to be used for the different RBGs in the RN-eNB link as well as the optimal set of RBRs to the UE-RN link, which the RN can redistribute among the UEs that it is serving.
    • 用户设备UE将其缓冲状态报告和数据发送到中继节点RN。 RN将数据存储在每个无线电承载组RBG的实际缓冲器中,并且将每个RBG的UE缓冲器占用存储在虚拟缓冲器中。 然后,RN将其自身的状态报告发送到具有实际的缓冲器占有率的信息和关于虚拟缓冲器占用的信息。 这使得eNBr能够预先知道进入RN的实际缓冲器的数据量以及这些缓冲器的当前占用率,以便更好地分配无线电资源。 此外,RN可以在UE和RN之间接收上行链路信道的探测,然后在RBR之间进行聚合,并作为特殊的UL CQI报告发送给eNBr。 因此,eNBr能够预测UE缓冲器中的数据将在RN的实际缓冲区(从平均UL CQI信息和虚拟缓冲器状态的附加信息)中出现多久,因此更好地分配用于不同的RBR的RBR RN-eNB链路中的RBG以及RN-RN链路的RBR的最佳集合,RN可以在其正在服务的UE中重新分布。
