| 摘 要： | 文章介绍时分同步码分多址长期演进(TD-LTE)中的无线资源管理(RRM)的关键技术,及TD-LTE系统的切换流程和协议设计。针对TD-LTE系统现存的一些迫切需求,提出了一种基于切换滞后差值(HOM)和触发时间(TTT)的切换算法,研究了在切换中HOM和TTT对系统性能的影响。动态仿真结果表明随着HOM和TTT的增长,在系统吞吐量没有明显下降的基础上,总切换次数有了大幅度的减少,降低了系统信令的交互频率,节省了系统资源并提高了切换效率。

| Abstract: | This paper introduces the key technology of Radio Resource Management （RRM） in TD-SCDMA Long Term Evolution （TD-LTE） as well as the handover flow and protocol design of the TD-LTE system. It proposes a handover algorithm based on Handover Hysteresis Margin （HOM） and Time-to-Tiger （TTT） that conforms to the requirements of TD-LTE. The impact of HOM and TTT on system performance is also analyzed. Simulation results show that with the growth of HOM and TTT, there is no significant drop in system throughput. However, the total number of handovers is greatly reduced. This reduces the frequency of signaling interaction, saves system resources, and improves handover efficiency. |
