摘要 为了解决下一代蜂窝系统的频谱资源受限问题,提出了一种基于中继的蜂窝移动通信系统频率规划方案.利用部分频率复用的思想规划频率,保证在相对提高小区边缘用户信干比的同时提高频谱利用效率.仿真结果表明,与其他频谱规划方案相比,该方案的频谱利用效率得到了改善,并且提升了小区边缘用户的吞吐量. This paper proposes a new frequency planning scheme for the proposed cellular wireless system using fix relay.Our scheme improves the frequency efficiency,while relatively improving the CEU's SIR through frequency planning based on fractional frequency reuse.The simulation results show that it can improve the performance of frequency efficiency compared with others scheme,CEU's average throughput is improved.
