1. A control information sending method, wherein the method comprises:
generating, by a network device, first control information, wherein the first control information comprises first information indicating two uplink transmission waveforms, wherein the two uplink transmission waveforms are configured by the network device for a terminal to transmit uplink data to the network device, wherein the first control information is insufficient for the terminal to determine, from the two uplink transmission waveforms, a waveform used to transmit the uplink data to the network device, and wherein the two uplink transmission waveforms indicated by the first control information are an orthogonal frequency division multiplexing (OFDM) waveform and a discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveform;
sending, by the network device, the first control information to the terminal;
generating, by the network device, second control information, wherein the second control information comprises second information indicating the terminal to use a particular uplink transmission waveform of the two uplink transmission waveforms comprised in the first control information; and
sending, by the network device, the second control information to the terminal.
