在蜂窝与Ad hoc混合网络中，小区边缘用户会受到邻近小区边缘用户的同频干扰。针对该问题，提出一种基于子载波分配的小区间干扰协调方案。该方案中的用户子载波分配选择算法具有信道增益选择性，且能对最小化子载波进行重利用，可提高小区边缘区域用户的通信性能。仿真结果证明，与软频率复用和部分频率复用方案相比，该方案能更有效地增加小区边缘用户的吞吐量。

Cell-edge users are vulnerable to the co-frequency interference of the neighboring cell-edge users in the cellular and Ad hoc hybrid network, for this problem, a subcarrier allocation scheme in order to mitigate the Inter-cell Interference(ICI) is proposed. This scheme can enhance the capacity of the users near the cell-edge area. Key features of the proposed scheme are the subcarrier allocation in a user selective manner considering the selectivity of the channel gain and subcarrier reuse minimization. Simulation results show that the proposed scheme yields better than Soft Frequency Reuse(SFR) scheme and Fractional Frequency Reuse(FFR) scheme for improving the throughput of the cell-edge users.
