Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether to perform a simplified uplink control information (UCI) multiplexing procedure or select an overlapping uplink channel having the highest priority and drop the remaining overlapping uplink channels. The UE may determine that a first symbol period of the physical uplink scheduled channel (PUSCH) is aligned with a first symbol period of the physical uplink control channel (PUCCH) and the UE may multiplex UCI with an uplink data transmission. The UE may transmit the multiplexed UCI and uplink data on the PUSCH and drop the PUCCH. The UE may perform UCI multiplexing for overlapping PUCCH and PUSCH, located on the same component carrier (CC). The UE may refrain from performing UCI multiplexing if the PUSCH and the PUCCH are located on different CCs, and may simultaneously transmit UCI and uplink data over the different CCs.
