Abstract: The present invention provides a method and device for transmitting an uplink signal in a cell configured in an unlicensed band. A user equipment performs clear carrier assessment (CCA) on a second cell configured in an unlicensed band, and when the CCA is successful, transmits a known signal notifying that the CCA is successful, on the second cell. A base station transmits, to the user equipment, uplink grant for the second cell only when detecting the known signal on the second cell.
