| Abstract: | In this paper,a modified soft frequency reuse(SFR) scheme is given to improve the performance of edge area and to mitigate the shortcomings of traditional SFR such as low business agility which is unable to adapt to dynamic spectrum allocation and distribution in long term evolution(LTE) system.In our method,a part of spectrum resource is allocated as the shared frequency band,and the edge region has higher priority.The simulation results show that the proposed method can effectively improve the throughput for those users at the edge area and increase the flexibility of spectrum allocation. |
