    摘要: An embodiment of the present invention relates to a method of a base station to transmit a signal in a wireless communication system. The method includes: transmitting Physical Downlink Control Channel (PDCCH), which includes scheduling information on a resource area of an unlicensed band over a licensed band; and transmitting a sequence, which includes the identifier of a terminal having the resource area allocated, over the unlicensed band. The timing at which the sequence is transmitted may be set prior to a resource area scheduled by the PDCCH.
