摘要：
The present invention relates to a method for transmitting a reference signal (RS) in a distributed multi-node system. The transmission method comprises: a step of constructing multiple channel state information reference signals (CSI-RSs) having power which is not zero in an intra-cell; and a step in which a base station transmits control information on the multiple CSI-Rss to a terminal. Here, the channel state information reference signals of multiple patterns may be transmitted in one subframe. The transmission method may further comprise a step of receiving feedback information on the channel state information reference signals from the terminal.
摘要（中）：
本发明涉及在分布式多节点系统中发送参考信号（RS）的方法。 传输方法包括：在小区内构造具有不为零的功率的多信道状态信息参考信号（CSI-RS）的步骤; 以及基站向终端发送关于多个CSI-Rss的控制信息的步骤。 这里，可以在一个子帧中发送多个模式的信道状态信息参考信号。 发送方法还可以包括从终端接收关于信道状态信息参考信号的反馈信息的步骤。
