Data transmission method and communications device

A data transmission method by a user equipment, comprising:

• receiving, from a base station, mapping information between a data flow identifier and a physical layer transmission technology identifier;
• storing the mapping information, wherein the mapping information comprises:
• a correspondence between the data flow identifier and the physical layer transmission technology identifier, wherein the physical layer transmission technology identifier identifies a physical layer transmission technology comprising at least one of a waveform technology, a coding technology, a higher order modulation technology, or a space modulation technology;
• determining a to-be-scheduled data flow;
• determining from the mapping information and according to a data flow identifier of the data flow, a physical layer transmission technology identifier corresponding to the data flow;
• generating according to the data flow, a transport block which is corresponding to the physical layer transmission technology identifier, so as to send the data flow to the base station by using the transport block, wherein different physical layer transmission technology identifiers are corresponding to different types of transport blocks;
• generating wireless communication data by performing processing, according to a physical layer transmission technology corresponding to the physical layer transmission technology identifier, on a transport block corresponding to the physical layer transmission technology identifier;
• and
• sending the wireless communication data to the base station.
