基于TD-SCDMA的R4与HSDPA混合组网系统级性能研究

[摘要] 文章认为R4和高速下行数据接入(HSDPA)的混合组网方式是目前比较合理的组网方式，可以减少建设成本，并降低管理维护和优化的复杂度，是主流运营商倾向的组网方式。文章提出通过理论计算结合系统级仿真手段可以对基于TD-SCDMA的R4与HSDPA业务混合组网前后系统性能进行对比研究，并提出通过优化HSDPA业务信道发射功率、调度算法、无线资源管理(RRM)算法等多种手段可以提升混合组网后系统性能。

[Abstract] In this paper, we describe a hybrid networking comprising TD-SCDMA R4 and high-speed downlink packet access (HSDPA). Such a network can reduce network construction cost, and optimize OAM. This is the most reasonable mode of networking and has become the trend with operators. System performance before and after TD-SCDMA R4/HSDPA hybrid networking can be theoretically determined and confirmed by system-level simulations. By optimizing the HSDPA traffic channel transmit power, scheduling algorithm, radio resource management (RRM) algorithm, performance of the hybrid network can be improved.
