Abstract: Provided are configuration information transmission method and device. The method includes: transmitting configuration information, where the configuration information includes at least one of the following: configuring N sets of data channel configuration information for one frequency domain bandwidth, configuring M sets of control channel resource configuration information for one frequency domain bandwidth, or configuring C sets of measurement reference signal configuration information for one frequency domain bandwidth, where N, M, and C are integers greater than or equal to 1. The above solution resolves the issue of the lack of data transmission between multiple TRPs and a terminal in the related art. Multiple sets of configuration information are configured for one frequency domain bandwidth, such that different configuration information can be used in multi-TRP transmission, thereby realizing data transmission between multiple TRPs and a terminal.
