REFERENCE SIGNAL MAPPING METHOD AND DEVICE

摘要

The present disclosure provides a reference signal mapping method and device. The method provided in the present disclosure comprises: determining, according to an N-port reference signal pattern, a mapped RE position of a CSI-RS, wherein N equals 12 or 16; and performing, according to the determined RE position, resource mapping for the CSI-RS. The mapped RE position of the CSI-RS in the N-port reference signal pattern is determined from a mapped RE position of a CSI-RS in one or more of 2-port, 4-port and 8-port reference signal patterns. CSI-RS mapping for 12 ports or 16 ports can be achieved by employing the present disclosure, thus realizing CSI-RS transmission for 12 ports or 16 ports.
