Abstract: The present disclosure provides a reference signal mapping method and a reference signal mapping device. An N-port reference signal pattern is acquired in accordance with a 4-port or 8-port reference signal pattern, and N is an integer greater than 16. The N-port reference signal pattern includes an 18-port, 20-port, 24-port, 28-port or 32-port reference signal pattern. In the case of mapping a reference signal, RE positions to which a CSI-RS is mapped are determined in accordance with the N-port reference signal pattern, and resource mapping is performed on the CSI-RS in accordance with the RE positions, so as to map more-than-16-port CSI-RS, thereby to transmit the more-than-16-port CSI-RS.
