Method and apparatus for transmitting uplink control information in wireless communication system

User equipment (UE), comprising:

• a radio frequency (RF) unit transmitting or receiving a radio signal;
• and
• a processor connected with the RF unit,
• wherein the processor receives a first parameter and a second parameter and
• transmits, based on whether the first parameter is set true or set false, first acknowledgment/negative-acknowledgement (ACK/NACK) information and a channel quality indicator (CQI) through a first physical uplink control channel (PUCCH) format or second ACK/NACK information and the CQI through a second PUCCH format,
• wherein the first parameter indicates whether simultaneous transmission of the first ACK/NACK information and the CQI is allowed to the user equipment, and the second parameter indicates whether the user equipment performs simultaneous transmission of the second ACK/NACK information and the CQI multiplexing on the second PUCCH format,
• wherein if the first parameter is set true and if the first ACK/NACK information corresponds to a physical downlink control channel (PDCCH) indicating downlink semi-persistent scheduling (SPS) release, and a downlink assignment index (DAI) value in the PDCCH is equal to 1, the CQI and the first ACK/NACK information are transmitted through the first PUCCH format, and
• if the first parameter is set false, and if the second parameter is set true, and if one PUCCH resource is determined among four resources configured by a higher layer signal, and if a total number of bits corresponding to the second ACK/NACK information and the CQI is not larger than 22, the second ACK/NACK information and the CQI are transmitted through the second PUCCH format.

A method for a user equipment in a wireless communication system, the method comprising:

• receiving a first parameter and a second parameter, wherein the first parameter indicates whether simultaneous transmission of a first acknowledgment/negative-acknowledgement (ACK/NACK) information and a channel quality indicator (CQI) is allowed for the user equipment, and the second parameter indicates whether the user equipment performs simultaneous transmission of the second ACK/NACK information and the CQI multiplexing on a second physical uplink control channel (PUCCH) format;
• transmitting the CQI and the first ACK/NACK information through a first PUCCH format, based on the first parameter being set true, the first ACK/NACK information corresponding to a physical downlink control channel (PDCCH) indicating downlink semi-persistent scheduling (SPS) release, and a downlink assignment index (DAI) value in the PDCCH being equal to 1;
• and
• transmitting the second ACK/NACK information and the CQI through the second PUCCH format based on the first parameter being set false, the second parameter being set true, one PUCCH resource being determined among four resources configured by a higher layer signal, and a total number of bits corresponding to the second ACK/NACK information and the CQI being not larger than 22.
