A channel transmission method, wherein the method comprises: determining, by a terminal, a transmission mode of uplink information of at least two physical uplink control channels, PUCCH, according to time domain position and/or processing time of the at least two PUCCHs under a condition of determining that resources of the at least two PUCCHs have an overlapping part in time domain, wherein the uplink information comprises an HARQ-ACK feedback; characterized in that: the at least two PUCCHs at least comprise a first PUCCH and a second PUCCH, uplink information of the first PUCCH is a first feedback codebook, and uplink information of the second PUCCH is a second feedback codebook; wherein the method further comprises: 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. determining, by a terminal, a transmission mode of uplink information of at least two physical uplink control channels, PUCCH, according to time domain position and/or processing time of the at least two PUCCHs under a condition of determining that resources of the at least two PUCCHs have an overlapping part in time domain, wherein the uplink information comprises an HARQ-ACK feedback;
