Abstract

An uplink control information transmission method includes determining, by a terminal, uplink control information to be multiplexed over one target physical uplink channel for transmission. The uplink control information includes a first HARQ-ACK, a second HARQ-ACK, and CSI. The first HARQ-ACK has a higher priority than the second HARQ-ACK; determining a coding mode of the uplink control information on the target physical uplink channel based on a priority of the CSI and/or based on whether the CSI includes a second part of channel state information CSI-part 2, where the priority of the CSI includes a first priority or a second priority, the first priority being higher than the second priority; and encoding the uplink control information based on the coding mode and transmitting the encoded uplink control information on the target physical uplink channel.
