Abstract:
A method for transmitting Channel State Information-Reference Signal (CSI-RS) by a base station includes: transmitting, to a User Equipment (UE), information indicating M CSI-RS antenna ports and resource allocation information of CSI-RS resource configured by aggregating K groups, wherein M and k are integers greater than or equal to 2, respectively; mapping CSI-RSs corresponding to the M CSI-RS antenna ports on the CSI-RS resource; and transmitting, to the UE, the mapped CSI-RSs.
