Abstract: In an embodiment the method includes: determining, by a first communications device, a first subcarrier spacing corresponding to a first subband; and performing, by the first communications device, signal transmission on the first subband with a second communications device based on the first subcarrier spacing; or determining, by a first communications device, a second subcarrier spacing corresponding to a second subband; and performing, by the first communications device, signal transmission on the second subband with a second communications device based on the second subcarrier spacing. The first subcarrier spacing is different from the second subcarrier spacing, and both the first subcarrier spacing and the second subcarrier spacing are integral multiples of a basic frequency spacing; and both bandwidth of the first subband and bandwidth of the second subband are integral multiples of the basic frequency spacing.

Abstract: This application provides a communication method, a terminal, and a network device. The communication method includes: repeating, by a first terminal, to-be-transmitted uplink control information for N times to obtain a first data segment, where N is a positive integer; determining, by the first terminal, an orthogonal cover code based on N; multiplying, by the first terminal, the first data segment by the orthogonal cover code to obtain a second data segment; and sending, by the first terminal, the second data segment. By using the communication method, the terminal, and the network device provided in this application, frequency diversity gains of the uplink control information can be increased, transmission flexibility of the uplink control information can be improved, and resource utilization can be increased.
