Patent ID: 8428640

Claim:
A method for transmitting downlink control information in a fractional frequency reuse (FFR) system, the method comprising: dividing a service frequency band of the system into a plurality of frequency partitions (FPs); separately setting a transmission power level for each of the plurality of FPs; allocating 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 transmitting 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 from the first frequency and has a boosted transmissions power, and the indication information indicates the reuse 1 partition or the power-boosted reuse 3 partition.
