摘　　要：主要从无线接入网络选择、频谱分配和功率控制3个方面讨论了异构网络自优化技术的研究现状。同时提出了一种基于用户配对调度的功率控制博弈算法。仿真结果表明,相比传统的随机用户调度策略,该算法可有效提升信道容量。随后提出了一种联合优化部分频谱复用以及基站休眠模型。仿真结果表明,在能源消耗方面,该联合优化方法明显优于其他方案。Some self-optimization approaches are surveyed, such as wireless access network selection, spectrum resource al ocation and power control for HetNets. It proposes a user-pair-scheduling based power control game, simulation results show that the proposed algorithm outperforms the traditional stochastic-scheduling strategy in terms of enhancing the channel capacity. Then, a joint optimization of partial spectrum-reuse scheme and base-station-sleep model has been proposed. Simulation re-sults show that the joint approach outperforms the other schemes in terms of network’s total energy consumption.
