Method for transmitting and receiving signal in wireless communication system and device for performing same
A method for receiving a signal by a terminal, having a plurality of cells configured, in a wireless communication system according to an embodiment of the present invention comprises the steps of: assuming a first uplink subframe of a first cell, having a time division duplex (TDD) frame structure among a plurality of cells, to be a downlink subframe on the basis of a predetermined condition and blind-decoding same; and, if a downlink grant with respect to a second cell, located in an unlicensed band among the plurality of cells, is detected by means of the blind-decoding, receiving downlink data through the second cell, wherein the first uplink subframe is indicated as an uplink subframe by means of a first uplink-downlink subframe configuration in an enhanced interface mitigation and traffic adaptation (eIMTA) fallback comprised in a system information block type 1 (SIB 1) and at the same time is indicated as a downlink subframe by means of downlink hybrid automatic repeat request (HARQ) reference configuration in the eIMTA fallback.
