Method for receiving scheduling information of unlicensed spectrum cell and device thereof

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. More specifically, the present invention relates to a method and a device for performing scheduling by a cell using an unlicensed spectrum. Particularly, the present invention provides a method and a device for receiving, by a terminal, scheduling information of an unlicensed spectrum cell, the method comprising the steps of: configuring carrier aggregation or dual connectivity including a licensed spectrum cell and the unlicensed spectrum cell; setting a value indicating whether there is a field indicating a carrier of the licensed spectrum cell; and receiving the scheduling information of the unlicensed spectrum cell in the licensed spectrum cell, wherein the unlicensed spectrum cell uses a frequency of an unlicensed spectrum shared by one or more communication systems.
