该文针对OFDMA蜂窝系统中上行干扰特性,提出了基于IoT控制的小区间功率控制方法.该方法通过相邻小区相互交换干扰信息,对传统的功率控制进行修正,并根据调整原则和调整步长,提出了4种控制方法,使得系统IoT更稳定,吞吐量更高.仿真证实了这4种控制方法都优于传统未加IoT控制的功率控制方法,其中基于固定比较对象的自适应调整步长的功率控制方法最优.

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.
