Abstract: An uplink resource grant method includes receiving, by a terminal, configuration information from a network device, where the configuration information includes information about a first uplink resource and information about a second uplink resource, and searching, by the terminal, a search space for a downlink control channel to obtain grant information. The search space includes a first control channel candidate set when the downlink control channel carries grant information of the first (or the second) uplink resource, and the search space includes a second control channel candidate set when the downlink control channel carries grant information of the second (or the first) uplink resource or grant information of a downlink resource. The first control channel candidate set is the same as the second control channel candidate set.

Abstract: This application discloses a carrier switching solution for multi-carrier communication. A network device sends configuration information to a terminal. The configuration information includes first uplink carrier information and second uplink carrier information. The first uplink carrier information indicates that a first uplink carrier is an SRS switching-from uplink carrier. The second uplink carrier information indicates that a second uplink carrier is an SRS switching-to uplink carrier. At least one of the first uplink carrier and the second uplink carrier belongs to a cell including a supplementary uplink (SUL) carrier. The terminal may determine the SRS switching-from uplink carrier and the SRS switching-to uplink carrier in a plurality of configured uplink carriers based on the configuration information.
