Abstract: The present disclosure discloses a data processing method, a network device, and a terminal. In this method, a transmit end combines basic modulation symbols obtained after basic modulation is performed on all layers of data, to obtain a combined symbol vector X. The transmit end maps the symbol vector X to Q resource elements to obtain a data vector S. A symbol quantity of the symbol vector X is greater than a symbol quantity of the data vector S. The symbol quantity of the data vector S is Q. Q is a positive integer. Therefore, non-orthogonal spreading and superposition transmission of a plurality of terminals can be implemented in both uplink and downlink, thereby effectively improving transmission efficiency.
