A base station for allocating resources for an unlicensed band in a cellular network, the base station comprising:

• a controller configured to generate downlink control information comprising first information for resource assignment and second information indicating a plurality of scheduled uplink subframes in the unlicensed band;
• and
• a transceiver configured to transmit the downlink control information to a user equipment (UE) in a downlink subframe and to receive uplink data from the UE during the scheduled uplink subframes in the unlicensed band.
