Abstract: The present invention provides an information processing method, comprising: generating signaling comprising configuration information of channel state information process (CSI process); and sending the signaling comprising the configuration information of the CSI process. The present invention resolves the problem in the related art of being unable to use one CSI-RS resource overhead to meet the transmission requirements of multiple CSI-RSs having different port numbers, thereby achieving the technical effect of reducing resource overheads. The present invention also provides an information processing device and a storage medium.
