【摘要】：LTE (Long Term Evolution)是移動通信3G時代之后國際通行的另一主流移動通信標準,是3GPP組織于2005年3月全面啟動的以正交頻分復用(OFDM, Orthogonal Frequency Division Multiplexing)和多輸入多輸出(MIMO, Multiple Input Multiple Output)為主要技術基礎的長期演進項目。TD-LTE無線網絡規(guī)劃是根據一定規(guī)劃區(qū)域內用戶的覆蓋、容量以及通信質量需求,平衡一定的成本收益和設備利用率等因素,科學合理地進行該區(qū)域內TD-LTE無線網絡站址選擇、工程和無線參數規(guī)劃等設計工作。 相比FDD LTE, TD-LTE在規(guī)劃組網和運營方面尚處于摸索嘗試階段,還缺乏成熟的網絡規(guī)劃方法和組網理論。本文在對TD-LTE無線網絡規(guī)劃的特點、流程和方法進行探討的基礎上,采用系統(tǒng)級仿真工具,對規(guī)劃組網中格外重要的多天線與傳輸模式規(guī)劃和頻率規(guī)劃進行科學探究。通過系統(tǒng)級仿真研究結合中國移動TD-LTE規(guī)模試驗網外場測試結果的手段得到科學實用、能對TD-LTE大規(guī)模規(guī)劃組網起到參考作用的規(guī)劃方案。
[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.
