Disclosed are a method for processing multi-transmission reception point (TRP) data, a base station, a terminal, and a storage medium, used for solving the problem in the prior art of low reliability of data transmission when data is transmitted by using multiple TRPs. The method includes a base station generates a resource allocation instruction and a quasi-co-location (QCL) instruction according to the mapping relations between a transmission coding block of data to be transmitted and multiple TRPs, and the QCL instruction is used for indicating the associations between an allocated resource and the QCL identifiers of the multiple TRPs, and the allocated resource comprises a time-frequency resource or a demodulation reference signal (DMRS) port resource; and sends downlink control information (DCI) to a user terminal, the DCI comprising at least the resource allocation instruction and the QCL instruction as well as a data merging and detection instruction.
