METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

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.

1. A method for transmitting, by user equipment, uplink control information (UCI) through a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising:
determining, based on a PUCCH format dependent value, transmission power to be applied to an uplink control channel of a subframe, wherein PUCCH formats are classified according to a modulation scheme and a number of bits transmitted in the subframe; and transmitting at least one type of UCI at the determined transmission power in the uplink control channel, wherein if the PUCCH format is PUCCH format 3 which uses quadrature phase shift keying as the modulation scheme and in which 48 bits are transmitted, and if the at least one type of UCI includes an acknowledgement/not-acknowledgement (ACK/NACK) and periodic channels state information (CSI), the PUCCH format dependent value is determined based on a number of bits of the ACK/NACK and a number of bits of the periodic CSI.
