Apparatus and method for allocating downlink control channel

A device configured to transmit downlink control information in a fractional frequency reuse (FFR) system, the device comprising:

• a processor configured to
• divide a service frequency band of the system into a plurality of frequency partitions (FPs),
• separately set a transmission power level for each of the plurality of FPs,
• allocate non-user-specific control information to one FP of the plurality of FPs, the non-user-specific control information being information that is not dedicated to a specific user or a specific group of users, and
• transmit indication information to a terminal through a super frame header (SFH), the indication information indicating where the non-user-specific control information is allocated among the plurality of FPs,
• wherein when the plurality of FPs comprises a reuse 1 partition and a power-boosted reuse 3 partition:
• the reuse 1 partition is a first FP using a first frequency,
• the power-boosted reuse 3 partition is a second FP among 3 FPs using 3 frequencies different with the first frequency and has a boosted transmission power, and
• the indication information indicates the reuse 1 partition or the power-boosted reuse 3 partition.
