Method for detecting downlink control information and apparatus therefor

A UE for detecting downlink control information in a wireless communication system, the UE comprising:

• a radio frequency (RF) unit for transmitting or receiving a radio signal to or from a specific cell;
• and
• a processor connected to the RF unit and configured to:
• detecting first downlink control information transmitted from the specific cell,
• detecting second downlink control information included in a shortened downlink control channel, based on resource information on the shortened downlink control channel included in the first downlink control information, when the first downlink control information is detected, and
• changing at least one of a shortened downlink data channel, a shortened uplink data channel, and a transmission and reception timing of ACK/NACK signals, which are previously configured based on capability of the UE, when the first downlink control information is not detected.
