A method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a repetition configuration indicating a number of repetitions of physical uplink control channel (PUCCH) transmission. The method also includes transmitting, to the base station, a first repetition of the PUCCH transmission in a first slot on a first component carrier based on receiving the repetition configuration. The method further includes transmitting, to the base station, a second repetition of the PUCCH transmission in a first candidate slot on the first component carrier or a second component carrier based on the first candidate slot being an earliest slot after the first slot.
