Abstract: When a network device in embodiments of the present invention sends bandwidth resource indication information to a terminal by using downlink control information, the network device may impose some constraints on uplink transmission mode—related configuration information or SRS-related configuration information on an indicated bandwidth resource, and other indication information carried in the downlink control information, so that no ambiguity occurs when the terminal parses the bandwidth resource indication information. Alternatively, when a side of a terminal receives bandwidth resource indication information sent by a network device by using downlink control information, the terminal parses, in an unambiguous interpretation manner, configuration information on a bandwidth resource indicated by the bandwidth resource indication information in the downlink control information. Therefore, a BWP is smoothly switched to perform uplink transmission, uplink transmission efficiency can be improved, and system robustness can be improved.
