【摘要】：LTE (Long Term Evolution)是移动通信3G时代之后国际通行的另一主流移动通信标准,是3GPP组织于2005年3月全面启动的以正交频分复用(OFDM, Orthogonal Frequency Division Multiplexing)和多输入多输出(MIMO, Multiple Input Multiple Output)为主要技术基础的长期演进项目。TD-LTE无线网络规划是根据一定规划区域内用户的覆盖、容量以及通信质量需求,平衡一定的成本收益和设备利用率等因素,科学合理地进行该区域内TD-LTE无线网络站址选择、工程和无线参数规划等设计工作。 相比FDD LTE, TD-LTE在规划组网和运营方面尚处于摸索尝试阶段,还缺乏成熟的网络规划方法和组网理论。本文在对TD-LTE无线网络规划的特点、流程和方法进行探讨的基础上,采用系统级仿真工具,对规划组网中格外重要的多天线与传输模式规划和频率规划进行科学探究。通过系统级仿真研究结合中国移动TD-LTE规模试验网外场测试结果的手段得到科学实用、能对TD-LTE大规模规划组网起到参考作用的规划方案。
[Abstract]:LTE (Long Term Evolution) is another mainstream mobile communication standard in the world after 3G era. TD-LTE wireless network planning, which is a long-term evolution project based on orthogonal frequency division multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) and multi-input and multi-output (MIMO, Multiple Input Multiple Output), which was launched by 3GPP organization in March 2005, is based on the coverage of users in a certain area. Capacity and communication quality requirements, balancing certain factors such as cost, income and equipment utilization, scientific and reasonable TD-LTE wireless network site selection, engineering and wireless parameter planning and other design work. Compared with FDD LTE, TD-LTE, it is still in the trial stage of planning and operation, and lacks of mature network planning method and networking theory. Based on the discussion of the characteristics, processes and methods of TD-LTE wireless network planning, this paper uses system-level simulation tools to scientifically explore the planning of multi-antenna and transmission mode and frequency planning, which are particularly important in the planning and networking of the network. Through system-level simulation research combined with the results of field test of China Mobile TD-LTE scale Test Network, a scientific and practical plan can be obtained, which can play a reference role in large-scale planning and networking of TD-LTE.
