Abstract: An information indication method is provided, including: A terminal-side device receives first higher layer signaling from a network-side device, where the first higher layer signaling is used to configure N bandwidth parts BWPs, and N is a positive integer. The terminal-side device receives downlink control information from the network-side device, where the downlink control information includes an indication field. When N is less than a maximum quantity of BWPs that can be configured through the first higher layer signaling when the terminal-side device is in a connected mode (for example, an RRC connected mode) or a maximum quantity of BWPs that can be determined by using candidate bit states of the indication field that is used to determine an active BWP and that is in the downlink control information, the indication field indicates a position of the active BWP located in an initial BWP and the N BWPs.
