Patent ID: 8774139

Claim:
A method of transmitting, by a user equipment, uplink control information in a wireless communication system, the method comprising: receiving downlink data; determining a first physical uplink control channel (PUCCH) resource for transmission of acknowledgement/negative acknowledgement (ACK/NACK) information for the downlink data and a second PUCCH resource for transmission of uplink control information other than the ACK/NACK information; and transmitting the ACK/NACK information and the other uplink control information by using the first PUCCH resource and the second PUCCH resource in an uplink subframe, respectively, when the first and second PUCCH resources are located at one side based on a center frequency in each slot of the uplink subframe, and dropping the transmission of the other uplink control information and transmitting the ACK/NACK information by using the first PUCCH resource when the first and second PUCCH resources are located at different sides based on the center frequency in each slot of the uplink subframe, wherein the first PUCCH resource is determined based on a first control channel element index of a physical downlink control channel (PDCCH) carrying control information of the downlink data.
