Abstract: A reference signal mapping method and a reference signal mapping device are provided. The reference signal mapping method includes steps of: determining a position of a RE to which a CSI-RS has been mapped in accordance with an N-port reference signal pattern, N being equal to 12 or 16; and performing a resource mapping operation on the CSI-RS in accordance with the determined position of the RE. The position of the RE to which the CSI-RS has been mapped in the N-port reference signal pattern being determined in accordance with a position of the RE to which the CSI-RS has been mapped in one or more of a 2-port reference signal pattern, a 4-port reference signal pattern and an 8-port reference signal pattern. As a result, it is able to achieve the 12-port or 16-port CSI-RS mapping, thereby to achieve the 12-port or 16-port CSI-RS transmission.
