Method and apparatus for sending radio channel reference signals

The invention discloses a method for sending radio channel reference signals. The method comprises: a network side determining and generating a terminal to carry out a set of or more sets of CRI-RS configuration used for CSI measurement, and notifying each set of CRI-RS configuration to the terminal through an RRC signaling; and the network side, according to each set of CRI-RS configuration, sending corresponding one or more CRI-RS to the terminal. The invention further discloses an apparatus for sending radio channel reference signals. Through the method and apparatus, the cost for signal measurement can be reduced.
