Abstract:
1. An apparatus for controlling interference, the apparatus comprising: an interference information receiving unit configured to receive interference information about at least one subchannel which is allocated to at least one node in an OFDMA system; a determination unit configured to determine that a data rate of the at least one node is less than a threshold based on the interference information about the at least one subchannel; an interference list creating unit configured to limit interference in the at least one subchannel until the data rate of the at least one node is greater than the threshold, and to create an interference list comprising the limited interference information; and a reporting unit configured to transmit the interference list comprising the limited interference information to a radio network controller (RNC), wherein the apparatus is included in a station controlled by the RNC, and the interference list transmitted to the RNC enables the RNC to create a base station list and a relay station list to limit data transmission for each subchannel allocated to the OFDMA system, and to transmit the base station list and relay station list to at least one base station in the OFDMA system.
