Abstract
Provided are a method for a terminal transmitting uplink control information (UCI) through a physical uplink control channel (PUCCH) in a wireless communication system, and a terminal using the method. A transmission power to be applied to the uplink control channel is determined on the basis of a value subordinate to a PUCCH format, and at least one type of UCI is transmitted from the physical uplink control channel by using the transmission power that is determined, wherein when the PUCCH format is PUCCH format 3, and the at least one type of UCI includes acknowledgement/negative-acknowledgement (ACK/NACK) and periodic channel state information (CSI), the value subordinate to the PUCCH format is determined on the basis of the number of bits of the ACK/NACK and the number of bits of the periodic CSI.
