Abstract: Provided in the embodiments of the present application are a channel state indication (CSI) information reporting and receiving method and a communication device, which are used to provide for a terminal in an NR system a solution for mapping CSI information to an uplink channel and transmitting the same. The method comprises: a terminal receives an uplink channel resource configuration signaling and/or a demodulation reference signal (DMRS) configuration signaling sent by a base station, and determines a mapping symbol set, wherein the DMRS configuration signaling is used to indicate the number of DMRSes configured by a system for an uplink channel and the time-frequency location of an occupied OFDM symbol, the uplink channel resource configuration signaling represents the time-frequency resource of the uplink channel, and the mapping symbol set is a set of symbols adjacent to the OFDM symbol; and the terminal measures a downlink channel, calculates CSI information, encodes the CSI information, and maps an information part comprising rank indication (RI) information onto an RE of at least one orthogonal frequency-division multiplexing (OFDM) symbol in the mapping symbol set to carry out transmission.
