    • A method for transmitting a downlink signal through coordinated beamforming with a neighboring cell at a serving cell in a wireless communication system is disclosed. The method includes transmitting first subframe information for designating one or more subframes to the neighboring cell, transmitting first Precoding Matrix Index (PMI) restriction related information including one or more PMIs to a User Equipment (UE) of the serving cell, wherein the PMIs form a beam so that interference affecting the neighboring cell in the one or more subframes has a constant characteristic, receiving first Channel State Information (CSI) reporting measured in the one or more subframes based on the first PMI restriction related information from the UE of the serving cell, and transmitting a downlink signal to the UE of the serving cell based on the first CSI reporting, wherein the neighboring cell receives CSI reporting corresponding to the neighboring cell, measured by the UE of the neighboring cell in the one or more subframes.
    • 公开了一种用于在无线通信系统中的服务小区处通过协调波束成形与相邻小区发送下行链路信号的方法。 所述方法包括:向所述相邻小区发送用于指定一个或多个子帧的第一子帧信息,向所述服务小区的用户设备(UE)发送包括一个或多个PMI的第一预编码矩阵索引(PMI)限制相关信息,其中所述PMI形成 使得影响一个或多个子帧中的相邻小区的干扰具有恒定特性,基于来自所述服务的UE的所述第一PMI限制相关信息,接收在所述一个或多个子帧中测量的第一信道状态信息(CSI)报告 并且基于所述第一CSI报告向所述服务小区的所述UE发送下行链路信号,其中,所述相邻小区从所述一个或多个子帧中的所述相邻小区的所述UE测量到的与所述相邻小区相对应的CSI报告。
