| 摘 要： | 通过约束小小区下行链路的传输功率来抑制相邻小小区之间的干扰.同时,使用了一种低复杂度的子载波分配方案,可以使得小小区的下行速率尽可能地提高.在对小小区进行下行链路发射功率控制时,使用广义注水算法给出了小小区下行传输功率的最优解.仿真结果显示,子载波选择方案和功率分配算法,在提高小小区的下行传输速率的同时,有效控制了相邻小区间的干扰.

| Abstract: | In order to control the level of interference among adjacent small-cells effectively,in this paper,we suppress the interference between adjacent small-cells through controlling the small-cell downlink transmission power.Meanwhile,we use a low complexity subcarrier allocation scheme,making small-cell downlink rate be improved as much as possible.In small cell downlink transmission power control,we use a generalized water-filling algorithm which gives the optimal solution of downlink transmission power.Simulation results show that subcarrier allocation scheme and power allocation algorithm can improve small-cell downlink transmission rate and control the level of interference between adjacent small-cell effectively. |

| Keywords: | small-cell interference suppression power control generalized water-filling algorithm |
