The present invention relates to a wireless communication system, and more particularly, to a method for detecting a downlink control channel in a wireless communication system and to an apparatus for same. The method by which a terminal receives downlink control information in a wireless communication system, according to one example of the present invention, includes the steps of: receiving information elements, including information for setting a plurality of downlink subframe sets and information for representing a downlink control channel type for each of the plurality of downlink subframe sets, from a base station; determining the resource location to which the control is mapped in a specific downlink subframe set according to the type of the control channel; and monitoring a control channel corresponding to the control channel type at the resource location of the downlink subframe belonging to the specific downlink subframe set and receiving the downlink control information transmitted through the control channel.
