Abstract: This application provides a network device-based communication method, where channel resources are divided according to a specific rule. The method includes: determining, by a network device, at least two channels, where a spacing between center frequencies of two adjacent channels in the at least two channels is a positive integer multiple of a subcarrier spacing or a positive integer multiple of a resource block RB spacing; and communicating, by the network device, by using at least one of the at least two channels. Channel resource division is determined based on the spacing between center frequencies of two adjacent channels, implementing adaptation to an application scenario in which a bandwidth is flexible.
