    • The present invention refers to channel estimation in a communications network. According to the present invention, first two reference signals are transmitted by a base station to a set of mobile nodes in said communications network, wherein said base station includes first two antenna ports and wherein each of said first two reference signals refers to one antenna port of said first two antenna ports. Further, at least one second reference signal is transmitted by said base station to a cooperating mobile node, wherein said cooperating mobile node is included in said set of mobile nodes; said cooperating mobile node is assigned to a cooperation area in said communications network, said cooperation area being defined by said base station; and said at least one second reference signal refers to a corresponding further antenna port of further antenna ports included in said base station.
    • 本发明涉及通信网络中的信道估计。 根据本发明,前两个参考信号由基站发送到所述通信网络中的一组移动节点,其中所述基站包括前两个天线端口,并且其中每个所述前两个参考信号是指一个天线端口 的前两个天线端口。 此外,至少一个第二参考信号由所述基站发送到协作移动节点,其中所述协作移动节点包括在所述一组移动节点中; 所述协作移动节点被分配给所述通信网络中的协作区域,所述协作区域由所述基站定义; 并且所述至少一个第二参考信号是指包括在所述基站中的另外的天线端口的对应的另外的天线端口。
