The invention relates to the technical field of NB-IoT networks, in particular to an NB-IoT hybrid retransmission method and system. The system comprises a physical layer and a protocol stack, the physical layer and the protocol stack are operated by different cores of a processor, and the method comprises the steps that S100, the physical layer judges whether current data uplink is retransmittedor newly transmitted, if yes, S101 is executed, and if not, S102 is executed; the method comprises the steps that S101, a physical layer obtains data from a cache and sends the data, and an uplink sending process is ended; S102, the physical layer submits the related information to a protocol stack for processing; s1022, the protocol stack generates a protocol data unit according to the related information submitted by the physical layer and sends the protocol data unit to the physical layer; S1023, the physical layer receives the protocol data unit and sends the protocol data unit, and the uplink sending process is e
