Abstract: A method for controlling interference between cells of a terminal in a wireless communications system for the uplink non real-time data transmission is provided to improve system throughput by distributing RoT(Rise of Thermal) in a divided cell by RoT which restricts the number of users receiving the service. RoT value is allocated by the divided area(S330). A data service supplies an outmost area according to the allocated RoT in a remaining area(S340). The RoR(Received power over ROT) of the received signal strength indication calculates the terminal of each outer-most region and the roT value allocated to the outer-most region(S350). The region having maximum ROR is determined as the enclosure area(S360). If the system throughput reduces, the service is provided according to the allocated RoT(S390).
