Abstract: A method for acquiring uplink grant information, UE, and a base station are provided, where the method includes: obtaining, by UE, configuration signaling that includes a code channel number of a downlink control channel, and monitoring, on at least one code channel of the downlink control channel according to the configuration signaling, a channel that bears uplink grant information. During implementation of HSUPA by applying embodiments of the present invention, code channel resources of a downlink control channel that are supported by the UE are more than code channel resources of an uplink control channel; therefore, when a channel that bears uplink grant information is sent by using a code channel resource of the downlink control channel, flexibility of scheduling the UE by a system can be increased, and overheads of downlink code channel resources can also be reduced.

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.
