4. The method of claim 1 , wherein the first end time is earlier than the second end time, or the first end time is later than the second end time.

5. A terminal device, comprising a memory, a transceiver, and a processor, wherein the memory is used for storing instructions, the processor is used for executing the instructions stored in the memory, and when the processor executes the instructions stored in the memory, the processor is caused to:

control the transceiver to receive first indication information sent by a network device at a first starting time, the first indication information being used for indicating the terminal device to accomplish activation or deactivation a secondary cell of the terminal device before a first end time;

control the transceiver to receive second indication information sent by the network device at a second starting time, the second indication information being used for indicating the terminal device to accomplish the activation or the deactivation of the secondary cell before a second end time, wherein the second starting time is later than the first starting time and earlier than the first end time, and the terminal device does not accomplish the activation or the deactivation of the secondary cell according to the first indication information at the second starting time; and

determine to activate or deactivate the secondary cell only according to the first indication information or the second indication information after the second starting time, according to a preset rule,

wherein the preset rules comprises activating or deactivating, by the terminal device, the secondary cell according to one of the first indication information or the second indication information, and not performing, by the terminal device, the activation or the deactivation of the secondary cell indicated by the other one of the first indication information or the second indication information, and

wherein an indication by the first indication information is different from an indication by the second indication information.

6. The terminal device of claim 5 , wherein the first indication information is a medium access control (MAC) control element (CE), and the second indication information is downlink control information (DCI); or, the first indication information is the DCI, and the second indication information is the MAC CE.

7. The terminal device of claim 5 , wherein the first indication information is used for indicating the terminal device to activate the secondary cell, and the second indication information is used for indicating the terminal device to deactivate the secondary cell; or, the first indication information is used for indicating the terminal device to deactivate the secondary cell, and the second indication information is used for indicating the terminal device to activate the secondary cell.

8. The terminal device of claim 5 , wherein the first end time is earlier than the second end time, or the first end time is later than the second end time.

9. The terminal device of claim 6 , wherein the first indication information is used for indicating the terminal device to activate the secondary cell, and the second indication information is used for indicating the terminal device to deactivate the secondary cell; or, the first indication information is used for indicating the terminal device to deactivate the secondary cell, and the second indication information is used for indicating the terminal device to activate the secondary cell.

10. The terminal device of claim 6 , wherein the preset rule comprises:

activating or deactivating, by the terminal device, the secondary cell according to the first indication information, and not performing, by the terminal device, the activation or the deactivation of the secondary cell indicated by the second indication information.

11. The terminal device of claim 7 , wherein the preset rule comprises:

activating or deactivating, by the terminal device, the secondary cell according to the first indication information, and not performing, by the terminal device, the activation or the deactivation of the secondary cell indicated by the second indication information.

12. The terminal device of claim 6 , wherein the preset rule comprises:

activating or deactivating, by the terminal device, the secondary cell according to the second indication information, and not performing, by the terminal device, the activation or the deactivation of the secondary cell indicated by the first indication information.

13. A non-transitory computer readable medium, storing a computer program comprising instructions which, when being executed by a computer, causes the computer to:

receive first indication information sent by a network device at a first starting time, the first indication information being used for indicating a terminal device to accomplish activation or deactivation of a secondary cell of the terminal device before a first end time;

receive second indication information sent by the network device at a second starting time, the second indication information being used for indicating the terminal device to accomplish the activation or the deactivation of the secondary cell before a second end time, wherein the second starting time is later than the first starting time and earlier than the first end time, and the terminal device does not accomplish the activation or the deactivation of the secondary cell according to the first indication information at the second starting time; and
