Method and apparatus for transmitting different uplink control information in wireless communication system
A method by a terminal in a wireless communication system is provided. The method includes identifying a first physical uplink control channel (PUCCH) format for an acknowledgement/non-acknowledgement (ACK/NACK) and a second PUCCH format for a scheduling request (SR), identifying that a transmission of the ACK/NACK and a transmission of the SR overlap in a slot, transmitting, to a base station, the ACK/NACK in the slot based on the first PUCCH format being PUCCH format 0, and transmitting, to the base station the ACK/NACK without the SR in the slot, based on the first PUCCH format being PUCCH format 1 and the second PUCCH format is PUCCH format 0.
