transmitting, by the terminal, the first feedback codebook and the second feedback codebook through a multiplexing channel under a condition of determining that the uplink information of the first PUCCH and the uplink information of the second PUCCH adopt a multiplexing transmission mode;
wherein a resource of the multiplexing channel is determined based on a first indicator in a fourth DCI, and the first indicator is used for indicating the resource of the multiplexing channel;
wherein the first feedback codebook is used for transmitting feedback information corresponding to a first PDSCH set, the second feedback codebook is used for transmitting feedback information corresponding to a second PDSCH set, and priority of the first feedback codebook is higher than priority of the second feedback codebook; the first PDSCH set are scheduled by at least one DCI, and the fourth DCI refers to last DCI in the at least one DCI.

2. The method according to claim 1 , wherein the at least two PUCCHs comprise a first type of PUCCH and a second type of PUCCH;
the determining, by a terminal, a transmission mode of uplink information of at least two PUCCHs according to time domain position of the at least two PUCCHs, comprises:
determining, by the terminal, that the uplink information of the at least two PUCCHs adopts a multiplexing transmission mode if a time domain ending position of the first type of PUCCH is in the back of or the same as a time domain ending position of the second type of PUCCH.

3. The method according to claim 2 , wherein the method further comprises:
receiving, by the terminal, first configuration information sent by a network device, wherein the first configuration information is used for determining a candidate PUCCH set, and a time domain ending position of any candidate PUCCH in the candidate PUCCH set is in the front of or the same as the time domain ending position of the first type of PUCCH;
