A terminal according to an embodiment of the present invention can: encode a plurality of UCIs comprising a first UCI and a second UCI; perform resource mapping on the encoded bits of the plurality of UCIs on a single physical uplink channel; and perform uplink transmission on the basis of the resource mapping. Even when the first UCI and the second UCI have different priorities, the terminal can separately encode the first UCI and the second UCI on the basis that the first UCI and the second UCI are configured to be multiplexed on the single physical uplink channel, and perform the resource mapping on the second UCI having the lower priority on the basis of the resource mapping of the first UCI having the higher priority.
