| 摘 要： | 将软频率复用(SFR)引入到由毫微微小区和宏小区组成的双层异构网络中,提出基于软频率复用的小区间干扰协调(ICIC)方案.先根据SFR方法对宏小区进行频率资源分配,然后使毫微微小区用户使用宏小区用户未占用的频率资源.仿真结果表明:该方案能有效地解决宏小区和毫微微小区间的同频干扰问题.

| Abstract: | In this paper,soft frequency reuse (SFR) is introduced as an effective Inter-cell Interference Coordination (ICIC) scheme to overcome interference among femtocells and macrocells.While a macrocell allocates frequency band using a SFR map,femtocell chooses sub-bands which are not used by the macrocell sub-area users to avoid interference.Simulation results show that the proposed scheme can solve the problem of interference among macrocells and femtocells. |

| Keywords: | heterogeneous network co-channel interference frequency allocation soft frequency reuse inter-cell interference coordination |
