The first configuration information includes a serving cell set configured for a terminal device, and indicates a status of a secondary cell. The first network node sends the first configuration information and first indication information to the terminal device, where the first indication information includes information about a status of at least one secondary cell, and the at least one secondary cell belongs to the serving cell set.
