| 摘 要： | 提出了HetNet中基于上行CoMP的动态多小区接入算法(UCDS),动态选择协作基站,利用CoMP机制,改善小区边缘用户的上行传输性能。进一步地,提出了基于二次判决的协作小区选择算法(DJCS),以减少参与协作的基站数,降低协作复杂度并节省基站端资源。仿真结果表明,UCDS算法能显著提高边缘用户的平均吞吐率和传输能效,而DJCS算法在保证用户性能的情况下,降低了基站端的能耗。

| Abstract: | A CoMP-based uplink dynamic muhicell Selection （UCDS） algorithm in HetNet is proposed. By dynamically selecting coordinated stations and adopting the CoMP mechanism, the algorithm can improve the uplink transmission performance of edge users. Then a double judgment-based CoMP cell selection （DJCS） algorithm is put forward to reduce the number of coordinated stations, which can reduce the complexity of collaboration and save resources of base stations. The simulation results show that the UCDS algorithm can significantly improve the average throughput and transmission efficiency of edge users, and DJCS algorithm can reduce the energy consumption of base stations without losing too much performance for edge users. |
