Abstract Considering the uplink inter-cell interference in the OFDMA cellular system, an inter-cell power control method based on IoT is proposed. This method gives an amendment on the traditional power control through the exchange of the interference of the neighbor cells, and in accordance with the adjustment principle and adjustment step, four power control methods are put forward, which can make IoT more stable and have higher throughput. The simulation results show that all these four methods are superior to the traditional power control method, in which, the adaptive step power control combining with fixed target IoT is optimal.
