The present invention relates to a wireless communication system, and more particularly, to an uplink control information transmitting/receiving method and device. A method for a terminal to transmit acknowledgement information in a wireless communication system according to an embodiment of the present invention includes: determining whether the transmission of a scheduling request is set in one uplink subframe, where acknowledgement information on downlink transmission in a downlink subframe set including M(M‰¥1) downlink subframes is to be transmitted; determining a Physical Uplink Control Channel (PUCCH) format and a resource with which the acknowledgement information is to be transmitted; and transmitting the acknowledgement information by using the PUCCH format and the resource. Here, if the transmission of the scheduling request is set in the one uplink subframe, there is no Semi-Persistent Scheduling (SPS) releasing Physical Downlink Control Channel (PDCCH) in the downlink subframe set. If the acknowledgement information corresponds to only one Physical Downlink Shared Channel (PDSCH) indicated by the detection of a corresponding Physical Downlink Control Channel (PDCCH) received on only a Primary Cell (PCell) in the downlink subframe set, and a Downlink Assignment Index (DAI) value of the PDCCH is 1, the acknowledgement information and the scheduling request may be transmitted using PUCCH format 1b. |
