Wherein, the first information is used for determining candidate carrier set, includes multiple carrier waves in the candidate carrier set；Institute It states the carrier wave in candidate carrier set and is reserved for feedback information, the feedback information is used for determining to transmit on first carrier Wireless signal whether be correctly received；Second information is used for determining whether first wireless signal is correctly connect It receives, the target carrier is a carrier wave in the candidate carrier set；The execution is transmission and the operation is to receive, Or the execution is reception and the operation is to send.

9. according to the method described in claim 8, it is characterized in that, in the candidate carrier set include the first candidate carrier and Second candidate carrier, for given time, the corresponding subcarrier spacing of the first candidate carrier and second candidate carrier Corresponding subcarrier spacing is different.

10. the method according to any claim in claim 8 or 9, characterized by comprising:

Step A0. sends third information on third carrier wave；

11. according to the method described in claim 9, it is characterized in that, the candidate carrier set only includes described first candidate Carrier wave and second candidate carrier, the subcarrier spacing that first candidate carrier uses are greater than second candidate carrier and adopt Subcarrier spacing, first wireless signal occupy M multicarrier symbol in time domain；If the M is not more than M1, described Target carrier is first candidate carrier, and otherwise the target carrier is second candidate carrier；The M and the M1 are equal It is positive integer.

12. according to the method described in claim 9, it is characterized in that, the candidate carrier set only includes described first candidate Carrier wave and second candidate carrier, the subcarrier spacing that first candidate carrier uses are greater than second candidate carrier and adopt Subcarrier spacing；If the subcarrier spacing that the first carrier uses is not less than the first thresholding, the target carrier is First candidate carrier, otherwise the target carrier is second candidate carrier.

13. the method according to any claim in claim 8 to 12, characterized by comprising:

Step A10. sends the 4th information；

14. according to the method for claim 13, which is characterized in that the 4th information originated in for the first moment in time domain, First wireless signal originated in for the second moment in time domain, the time difference between first moment and second moment Absolute value is equal to T, and the T is not more than T1；The T1 is greater than 0 real number；The T1 is that the fixed or described T1 is to pass through High-level signaling configuration.

15. a kind of user equipment that be used to communicate on multicarrier, characterized by comprising:

- the first receiving module receives the first information；

First processing module operates the first wireless signal on first carrier；

Second processing module executes the second information in target carrier；

16. a kind of base station equipment that be used to communicate on multicarrier, characterized by comprising:

- the first sending module sends the first information；

Third processing module executes the first wireless signal on first carrier；

Fourth processing module operates the second information in target carrier；
