detecting whether a preset information field of received downlink control information comprises the target information, and in response to that the preset information field comprises the target information, determining that the target information is received, wherein the preset information field has a variable length, the length of the preset information field is determined according to a number of carriers previously configured for the terminal, and each bit in the preset information field corresponds to a target operation of each target carrier.

9. The method of claim 8 , further comprising:

reporting traffic transmission demand information to the base station, wherein the traffic transmission demand information comprises carrier information corresponding to one or more first candidate carriers which the terminal instructs to activate or deactivate.

10. The method of claim 9 , wherein detecting whether the target information sent by the base station is received comprises:

detecting whether the target information sent by the base station is received on at least one target time unit, wherein the target time unit is a time unit separated from a time unit for reporting the traffic transmission demand information by a preset number of time units.

11. The method of claim 8 , wherein detecting whether the target information sent by the base station is received comprises:

detecting whether the received downlink control information conforms to a preset format, and in response to that the downlink control information conforms to the preset format, determining that the target information is received; or

detecting whether a value of a radio network temporary identity that scrambles a cyclic redundancy check code is a first preset value, and in response to that the value of the radio network temporary identity is the first preset value, determining that the target information is received.

12. The method of claim 11 , wherein determining the one or more target carriers according to the target information comprises:

in response to that a bit value in the target information is a second preset value, determining a carrier corresponding to a bit where the bit value is located is the target carrier.

13. The method of claim 8 , wherein detecting whether the target information sent by the base station is received comprises:

detecting whether a physical layer signal sent by the base station belongs to a plurality of preset physical layer signals, and

when the physical layer signal sent by the base station belongs to the plurality of preset physical layer signals, determining that the target information is received.

14. The method of claim 13 , wherein determining the one or more target carriers according to the target information comprises:

taking carrier information corresponding to a target physical layer signal as the carrier information corresponding to the one or more target carriers according to a corresponding relationship between physical layer signals and carrier information corresponding to second candidate carriers.

15. The method of claim 14 , wherein the corresponding relationship is determined by:

obtaining the corresponding relationship predefined in a protocol; or

receiving the corresponding relationship sent by the base station.

16. The method of claim 8 , wherein the target operation comprises an activation operation or a deactivation operation.
