The present invention relates to a wireless communication system, and more specifically, to a method and a device for transmitting/receiving uplink control information. The method for a terminal to transmit confirmation response information in a wireless communication system according to one embodiment of the present invention comprises: a step for determining a PUCCH (physical uplink control channel) format and resource, in which confirmation response information is transmitted in response to a downlink transmission in a downlink sub-frame set including M(M‰¥1)downlink sub-frame; and a step for transmitting the confirmation response information using the PUCCH format and resource in one uplink sub-frame. Here, one excess serving cell is set to a terminal, and the one excess serving cell can include one PCell and at least one SCell. In the determining step, the confirmation response information can be transmitted by determining to use a PUCCH format 1a/1b, and using the PUCCH format 1a/1b in the transmitting step, when a SPS (semi-persistent scheduling) releasing PDCCH (physical downlink control channel) does not exist in the downlink sub-frame set, and one PDSCH (physical downlink shared channel), which is indicated through the detection of a corresponding PDCCH having a DAI (downlink assignment index) value of one, exists in the downlink sub-frame set. |
