    Abstract: Provided are a method for channel information feedback in a multi-antenna system, and a terminal. The method comprises: a terminal receives CSI-RSs of M ports sent by a base station, and performs estimation according to the CSI-RSs to obtain M-dimensional downlink channel information; the terminal uses a transformation function Fk to perform a linear transformation on the M-dimensional downlink channel information, and obtains Nk-dimensional kth type channels, wherein k is greater than or equal to 1 and less than or equal to K, M≥Nk, and K≥1; the terminal uses a preset Nk-dimensional codebook to respectively perform channel information quantisation on the kth type channels, and determines a corresponding precoding matrix and precoding matrix indicator information (PMIk); the terminal selects S type channels from within K type channels, and feeds index numbers of the selected channels and corresponding PMI back to the base station.

    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.
