Abstract: The present invention provides a method for reference signal dropping and an apparatus for the method. A method for CSI-RS dropping comprises receiving first CSI-RS configuration information including sub-frame information which is transmission resource information of a first CSI-RS and through which the first CSI-RS information is transmitted and resource element information which contains the first CSI-RS; receiving second CSI-RS configuration information including sub-frame information which is transmission resource information of a second CSI-RS and through which the second CSI-RS is transmitted and resource element information which contains the second CSI-RS; and in case transmission resources of the first CSI-RS according to the first CSI-RS configuration and transmission resources of the second CSI-RS according to the second CSI-RS configuration overlap with each other, determining according to a priority order whether a CSI-RS received from the overlapping transmission resources corresponds to the first or the second CSI-RS.
