Abstract
A data processing method, including performing, by a transmit end device, mapping processing on L layers of information bits to generate L layers of modulation symbol sequences, where each layer of modulation symbol sequence includes U modulation symbols, the L layers of modulation symbol sequences correspond to a same time-frequency resource, and the U modulation symbols include at least one non-zero modulation symbol and at least one zero modulation symbol, performing precoding processing on each layer of modulation symbol sequence according to a precoding matrix to generate L layers of modulation symbol sequence matrixes, and performing superposition processing on the L layers of modulation symbol sequence matrixes to generate a to-be-sent symbol sequence matrix, where the to-be-sent symbol sequence matrix includes T element sequences in a first dimension, and the to-be-sent symbol sequence matrix includes U element sequences in a second dimension.
