The present invention relates to a method and device for receiving downlink signals in a wireless communication system. In more detail, the method for receiving downlink signals includes: receiving first control information for downlink scheduling through a first slot in a pair of resource blocks (RBs), the first control information including allocation information on a plurality of continuous RBs; receiving data from a second slot in a pair of RBs if the pair of RBs includes the first control information in the plurality of continuous RBs; and, if the pair of RBs outside the plurality of continuous RBs includes the first control information, attempting to detect second control information on uplink scheduling through a second slot of a pair of RBs.
