Abstract: Disclosed is a method for communicating in a network supporting licensed and unlicensed bands. A terminal operation method comprises the steps of: detecting a control channel of a subframe #n transmitted from a base station; obtaining, from the control channel, a DCI for an uplink grant; executing channel sensing on the basis of channel connection-related information included in the DCI; and transmitting, to the base station, a subframe #(n+1) if the result of executing channel sensing is an idle state. Thus, the performance of the communication network may be improved.
