Abstract:
1. A method for controlling interference between a plurality of neighboring base stations for a terminal by a serving base station of the terminal in a communication system that can communicate between the base stations, the method comprising: receiving interference amount information on a first region of a downlink frame from the terminal by the serving base station; determining an interference amount estimate for the first region by the serving base station based on the interference amount information; comparing the interference amount estimate with an interference amount tolerance for the first region by the serving base station; and transmitting an interference indicator requesting reduction in transmission power for the first region to the plurality of neighboring base stations by the serving base station if it is determined that the interference amount estimate exceeds the interference amount tolerance, wherein the determining of the interference amount estimate comprises determining at least one of a Carrier to Interference and Noise Ratio (CINR) and a Received Signal Strength Indication (RSSI) for the first region included in the interference amount information and determining an estimate that is in proportion to a path loss and the transmission power for the first region included in the interference amount information and in inverse proportion to the CINR.
