A wireless communication method performed at a network device having one or more processors and memory storing a plurality of programs to be executed by the one or more processors, the method comprising:
- determining, by the network device, a first uplink carrier, wherein the first uplink carrier is one of a plurality of uplink carriers that can be used for a terminal device;
- and
- sending, by the network device, first information to the terminal device, wherein the first information indicates that the terminal device uses or can use the first uplink carrier to perform uplink transmission or processes the first uplink carrier,
- wherein the first information is carried in downlink control information (DCI), and
- wherein the method further comprises:
- sending, by the network device, second information to the terminal device, wherein the second information is used to activate or configure the first uplink carrier for the terminal device;
- determining, by the network device, a second uplink carrier in the plurality of uplink carriers that can be used for the terminal device;
- and
- sending, by the network device, third information to the terminal device, wherein the third information indicates that the terminal device uses the second uplink carrier to perform uplink transmission,
- wherein the first information and the third information are sent respectively in different scheduling processes of performing scheduling for the terminal device after the first uplink carrier is activated or configured by the second information.
A wireless communication method performed at a terminal device having one or more processors and memory storing a plurality of programs to be executed by the one or more processors, the method comprising:

- and
- send first information to the terminal device, wherein the first information indicates that the terminal device uses or can use the first uplink carrier to perform uplink transmission or processes the first uplink carrier,
- wherein the first information is carried in downlink control information (DCI), and
- wherein the method further comprises:
- sending, by the network device, second information to the terminal device, wherein the second information is used to activate or configure the first uplink carrier for the terminal device;
- determining, by the network device, a second uplink carrier in the plurality of uplink carriers that can be used for the terminal device;
- and
- sending, by the network device, third information to the terminal device, wherein the third information indicates that the terminal device uses the second uplink carrier to perform uplink transmission,
- wherein the first information and the third information are sent respectively in different scheduling processes of performing scheduling for the terminal device after the first uplink carrier is activated or configured by the second information.
A terminal device, comprising a processor, a memory, and a transceiver, wherein the processor, the memory, and the transceiver communicate with each other through internal connection channels to enable the terminal device to:
