Abstract:
1. A method of transmitting signals by a first base station in a mobile communication system, the method comprising: transmitting subframe allocation information to a second base station which is impacted by inter-cell interference from the first base station, wherein the subframe allocation information indicates a first type subframe transmitted by using normal power and a second type subframe transmitted by using lower power than the normal power; and transmitting, to a user equipment, the signals based on the subframe allocation information, wherein a CCE (control channel element) aggregation level of the second type subframe is configured higher than a CCE aggregation level of the first type subframe by incrementing a repetition count of control information corresponding to the second type subframe, and wherein the CCE aggregation level of the second type subframe is set to fill channel bandwidth of PDCCH (Physical Downlink Control Channel).
