A method for monitoring a downlink control channel in a wireless communication system and an apparatus for the method are disclosed. More specifically, a method for monitoring a downlink control channel of a user equipment (UE) in a wireless communication system comprises receiving, by the UE, configuration information of a first discontinuous reception (DRX) mode based on a first transmission time interval (TTI) and configuration information of a second DRX mode based on a second TTI from an evolved-NodeB (eNB); and monitoring, by the UE, a first downlink control channel in a first DRX listening interval within a first DRX cycle based on the configuration information of the first DRX mode and a second downlink control channel in a second DRX listening interval within a second DRX cycle based on the configuration information of the second DRX mode, wherein the second DRX cycle is set to be shorter than the first DRX cycle.
