Uplink control information transmitting/receiving method and device in a wireless communication system

A User Equipment (UE) for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system, comprising:

• a reception module for receiving a downlink signal from a Base Station (BS);
• a transmission module for transmitting an uplink signal to the BS;
• and
• a processor for controlling the UE including the reception module and the transmission module,
• wherein the processor is configured to,
• determine whether transmission of a scheduling request is configured in one uplink subframe in which ACK/NACK information for downlink transmission in a downlink subframe set including M(M≧1) downlink subframes is to be transmitted,
• determine a Physical Uplink Control Channel (PUCCH) format and resource through which the ACK/NACK information is to be transmitted, and
• transmit the ACK/NACK information using the PUCCH format and resource through the transmission module, and
• wherein, if transmission of the scheduling request is configured in the one uplink subframe, the ACK/NACK information and the scheduling request are transmitted using PUCCH format 1b, when a Semi-Persistent Scheduling (SPS) release Physical Downlink Control Channel (PDCCH) is not present in the downlink subframe set, the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding PDCCH received only on a Primary Cell (PCell) in the downlink subframe set and one PDSCH indicated by detection of the corresponding PDCCH received only on the PCell in the downlink subframe set, and a Downlink Assignment Index (DAI) value of the PDCCH is 1.
