Abstract: The present invention relates to a method for detecting control information of a terminal and an apparatus therefor in a wireless communication system supporting reconfiguration of a radio resource. Specifically, the present invention comprises the steps of: counting a discontinuous reception (DRX) timer in accordance with a first uplink-downlink configuration on a system information block (SIB) associated with a previously defined control channel; and monitoring the control channel on the basis of whether a radio resource reconfiguration message is received, wherein, if the reception of the radio resource reconfiguration message is successful, then the control channel is monitored according to a second uplink-downlink configuration indicated by the radio resource reconfiguration message.
