The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for transmitting uplink control information in a terminal for which a coordinated multi-point (CoMP) set including a plurality of cells is constructed in a carrier aggregation-based wireless communication system. The method comprises: a step of receiving a physical downlink control channel signal (PDCCH) for uplink scheduling; step of receiving a physical downlink shared channel (PDSCH) signal corresponding to the PDCCH signal on a secondary cell (SCell); and a step of transmitting PDSCH signal acknowledgement information via a physical uplink control channel (PUCCH). In cases where the SCell belongs to the CoMP set having a primary cell (PCell), a resource for the PUCCH is provided using an index for a specific resource unit from among one or more resource units used in transmitting the PDCCH signal. In cases where the SCell does not belong to the CoMP set having a PCell, a resource for the PUCCH is provided using a value of a specific field within the PDCCH signal.
