【摘要】：LTE (Long Term Evolution)是移動(dòng)通信3G時(shí)代之后國(guó)際通行的另一主流移動(dòng)通信標(biāo)準(zhǔn),是3GPP組織于2005年3月全面啟動(dòng)的以正交頻分復(fù)用(OFDM, Orthogonal Frequency Division Multiplexing)和多輸入多輸出(MIMO, Multiple Input Multiple Output)為主要技術(shù)基礎(chǔ)的長(zhǎng)期演進(jìn)項(xiàng)目。TD-LTE無(wú)線(xiàn)網(wǎng)絡(luò)規(guī)劃是根據(jù)一定規(guī)劃區(qū)域內(nèi)用戶(hù)的覆蓋、容量以及通信質(zhì)量需求,平衡一定的成本收益和設(shè)備利用率等因素,科學(xué)合理地進(jìn)行該區(qū)域內(nèi)TD-LTE無(wú)線(xiàn)網(wǎng)絡(luò)站址選擇、工程和無(wú)線(xiàn)參數(shù)規(guī)劃等設(shè)計(jì)工作。 相比FDD LTE, TD-LTE在規(guī)劃組網(wǎng)和運(yùn)營(yíng)方面尚處于摸索嘗試階段,還缺乏成熟的網(wǎng)絡(luò)規(guī)劃方法和組網(wǎng)理論。本文在對(duì)TD-LTE無(wú)線(xiàn)網(wǎng)絡(luò)規(guī)劃的特點(diǎn)、流程和方法進(jìn)行探討的基礎(chǔ)上,采用系統(tǒng)級(jí)仿真工具,對(duì)規(guī)劃組網(wǎng)中格外重要的多天線(xiàn)與傳輸模式規(guī)劃和頻率規(guī)劃進(jìn)行科學(xué)探究。通過(guò)系統(tǒng)級(jí)仿真研究結(jié)合中國(guó)移動(dòng)TD-LTE規(guī)模試驗(yàn)網(wǎng)外場(chǎng)測(cè)試結(jié)果的手段得到科學(xué)實(shí)用、能對(duì)TD-LTE大規(guī)模規(guī)劃組網(wǎng)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.
