Method for allocating resources in a wireless communication system and a device for the same

A method of transmitting a downlink control information (DCI) at a base station in a wireless communication system, the method comprising:

• assigning, by the base station, a set of Virtual Resource Blocks (VRBs) for the DCI on a downlink subframe configured for a specific device,
• wherein the DCI is related with the specific device;
• and
• transmitting, by the base station to the specific device, the DCI via a specific downlink control channel configured for the specific device by using the downlink subframe configured for the specific device,
• wherein the set of VRBs is configured to be a same VRB set in a first slot and a second slot of the downlink subframe configured for the specific device,
• wherein the set of VRBs is mapped on Physical Resource Blocks (PRBs) with the same index in each of the first slot and the second slot of the downlink subframe configured for the specific device,
• wherein if the set of VRBs is assigned in the first slot of the downlink subframe configured for the specific device, the DCI is configured for a downlink transmission for the specific device, and
• wherein if the set of VRBs is assigned in the second slot of the downlink subframe configured for the specific device, the DCI is configured for an uplink transmission for the specific device.
