Method for dynamic allocation of radio resources in wireless communication system and device therefor

A user equipment transmitting an uplink signal using a plurality of component carriers (CCs) in a wireless communication system supporting carrier aggregation, comprising:

• a transceiver;
• and
• a processor configured to control the transceiver, the processor further configured to:
• receive a time division duplex uplink-downlink (TDD UL-DL) configuration for a second carrier through a physical control channel or a higher layer signaling,
• wherein the TDD UL-DL configuration indicates an uplink-downlink resource configuration of a plurality of subframes,
• receive configuration information indicating at least one subframe among the plurality of subframes on the second component carrier from an eNode B via a first component carrier,
• wherein each of the indicated at least one subframe is a downlink subframe according to the TDD UL-DL configuration,
• if control information for the indicated at least one subframe is not received prior to the indicated at least one subframe, detect the control information for the indicated at least one subframe by performing a blind decoding in uplink subframes indicated by the TDD UL-DL configuration, and
• when the detected control information is an uplink grant, transmit the uplink signal to the eNode B in the at least one subframe via the second component carrier.
