Abstract: Embodiments of the present invention relate to a data transmission method and apparatus based on unequal error protection and a device. The method includes: segmenting, according to a quantity of symbol bits in a constellation diagram, a code block corresponding to data, to obtain segmented code blocks; performing rate matching on the segmented code blocks obtained by channel encoding, to obtain output code blocks; cascading the output code blocks according to the quantity of symbol bits in the constellation diagram, to obtain cascaded code blocks; and sending the cascaded code blocks to a terminal device.
