transmitting, in a case that priorities of carried contents of the first PUCCH and the second PUCCH are different, a PUCCH with a higher priority of a carried content between the first PUCCH and the second PUCCH within the one or more collision slots;

delaying transmission of a PUCCH with a lower priority of the carried content between the first PUCCH and the second PUCCH, or discarding a PUCCH with a lower priority of the carried content between the first PUCCH and the second PUCCH within the one or more collision slots, in a case that priorities of the carried contents of the first PUCCH and the second PUCCH are different.

4. The method according to claim 3 , wherein, a priority of the SR is higher than a priority of the CSI, and/or priorities of two CSIs are determined according to a predefined priority rule.

5. The method according to claim 2 , wherein, in a case that the configuration comprises the period of the carried content,

transmitting one of the first PUCCH and the second PUCCH within the one or more collision slots comprises:

transmitting a PUCCH with a short period of the carried content between the first PUCCH and the second PUCCH within the one or more collision slots;

delaying transmission of a PUCCH with a long period of the carried content between the first PUCCH and the second PUCCH, or discarding a PUCCH with a long period of the carried content between the first PUCCH and the second PUCCH within the one or more collision slots.

6. The method according to claim 1 , wherein, the starting time further comprises a position of a start symbol.

7. The method according to claim 2 , wherein, the configuration of at least one of the first PUCCH and the second PUCCH is a configuration of the second PUCCH, and the configuration comprises the format;

in a case that the format of the second PUCCH is format 0 or format 2, transmitting one of the first PUCCH and the second PUCCH within the collision slot comprises:

transmitting the second PUCCH within the one or more collision slots;

delaying transmission of the first PUCCH or discarding the first PUCCH within the one or more collision slots.

8. The method according to claim 2 , wherein, the configuration of at least one of the first PUCCH and the second PUCCH is a configuration of the second PUCCH, and the configuration comprises the transmission mode;

in a case that the transmission mode of the second PUCCH is single-slot transmission, transmitting one of the first PUCCH and the second PUCCH within the one or more collision slots comprises:

transmitting the second PUCCH within the one or more collision slots;

delaying transmission of the first PUCCH or discarding the first PUCCH within the one or more collision slots.

9. A terminal, comprising:
