Abstract: In the present application, a method is disclosed of transmitting a downlink data channel from a base station through a terminal in a wireless communication system. In particular, the method comprises the steps of: mapping the downlink data channel to a transmitting resource of a licensed bandwidth or a transmitting resource of an unlicensed bandwidth; and transmitting the mapped downlink data channel via the terminal. The step of mapping the downlink data channel is characterized by comprising the steps of: applying a frequency priority mapping technique when the downlink data channel is mapped to the transmitting resource of the licensed bandwidth; and applying a time priority mapping technique when the downlink data channel is mapped to the transmitting resource of the unlicensed bandwidth.
