摘要： Disclosed are a data transmission method, a terminal, and a base station. Determined is that a TB needs to be divided into M CBG; grouping, according to a preset grouping scheme, multiple CB produced when the one TB is code block segmented, thus diving the one TB into the M CBG; and transmitting data according to the M CBG, where M is a positive integer. The technical solution of the present invention solves the technical problem of low data transmission efficiency and low resource utilization rate in an LTE system found in the prior art.
