中文摘要：

采用直角的频率分割的细胞的继电器网络多重(OFDM ) 技术广泛地为下一代被接受了无线通讯由于它在扩大范围规模以及改善数据率的优点。为了改进用户设备(UE ) 的表演，接近房间边，到特别避免干扰从内部房间并且 intra 房间，一个提高的软频率复用计划在这份报纸被采用保证内部房间的干扰协作(ICIC ) 。与传统的频率分配工作相比，建议计划干扰知道、负担适应，它动态地处于可变交通负担状况在某些时间表方法下面在 UE 之中分配可得到的频率并且用干扰指示物提供的信息减轻干扰。它能在每条潜水艇隧道加 UE 的噪音比率(SINR ) 改进 signal-to-interference 因此启用系统完成更好的产量和堵住的概率性能。模拟结果证明建议计划可以在产量上完成理想的性能，堵住概率并且光谱在在不同交通负担下面的扇区的利用与另外的计划相比。

英文摘要：

Cellular relay networks adopting orthogonal frequency division multiple （OFDM） technology has been widely accepted for next generation wireless communication due to its advantage in enlarging coverage scale as well as improving data rate.In order to improve the performance of user equipments （UEs） near the cell edge,especially to avoid the interference from inter-cell and intra cell,an enhanced soft frequency reuse scheme is adopted in this paper to assure inter-cell interference coordination （ICIC）.Compared with traditional frequency allocation work,the proposed scheme is interference-aware and load-adaptive,which dynamically assigns available frequency among UEs under certain schedule method in variable traffic load condition and mitigates interference using information provided by interference indicator.It can improve signal-to-interference plus noise ratio （SINR） of the UE in each sub channel thus enable the system achieve better throughput and blocking probability performance.Simulation results prove that the proposed scheme may achieve desirable performance on throughput,blocking probability and spectral utilization in the sector under different traffic load compared with other schemes.
