The present invention relates to a method and a device for supporting LTE- or LTE-Advanced-based radio access technology (RAT) in an unlicensed spectrum and, more specifically, to a method and a device for performing scheduling of a cell using an unlicensed spectrum. Particularly, the present invention provides the method for receiving scheduling information of the unlicensed spectrum cell by a terminal, which comprises the steps of: configuring carrier aggregation or dual connectivity including a licensed spectrum cell and the unlicensed spectrum cell; setting a value indicating whether a carrier indicator field of the licensed spectrum cell is existed or not; and receiving the scheduling information of the unlicensed spectrum cell by the licensed spectrum cell, wherein the unlicensed spectrum cell uses the frequency of an unlicensed spectrum shared by one or more communication systems. |
