Abstract: A user equipment (UE) operation related to at least one of embodiments of the disclosure may include multiplexing a plurality of UCIs on a single physical uplink shared channel (PUSCH), and transmitting the single PUSCH in which the plurality of UCIs are multiplexed. Based on that the UE is configured to multiplex UCIs having different priorities on the same PUSCH, that a priority of a first UCI included in the plurality of UCIs is Priority-H higher than Priority-L, and that the first UCI with the Priority-H includes 2-part channel state information (CSI), the UE may drop all hybrid automatic repeat request-acknowledgement (HARQ-ACK) information of a second UCI with the Priority-L lower than the Priority-H, and map a first part of the CSI and a second part of the CSI onto the single PUSCH.
