Research On Network Planning Technology Of TD-LTE Wireless Macro Base Station

On December 4,2013,the State Ministry issued a formal TD-LTE operating license to the domestic three operators,China Mobile,China Telecom and China Unicom.Therefore,TD-LTE industry has a crucial stage in the commercial.By the end of 2014,about 500,000 TD-LTE base stations are going to be built in China in order to provide 4G commercial service for over 340 cities.This ambitious goal is relied on the maturity and good pre-planning TD-LTE technology.This thesis researches on the plan techniques about the network of TD-LTE radio station.Firstly,the development situation of communication technology was introduced.The related technology of wireless network planning stage was overviewed,including GSM network and WCDMA network planning features,and analyzes the key technology of TD-LTE,OFDM technology,MIMO technology and frame structure.Secondly,according to the characteristics of TD-LTE technology,the thesis summarized the objectives and principles of TD-LTE configuration macro base station network construction,and also introduced the original TD-SCDMA network planning for comparison.Then,the field survey was done for TD-LTE macro base station to make clear design principles,design process and design methods.Moreover,the simulation processing and analysis was done by the collected data.As the deployment of TD-LTE base station network is mostly based on the existing GSM or TD-SCDMA base station construction,it focuses on building programs and other content Antennas.Finally,the investigation about 2,3G networks in certain areas was done,and the collected data was sorted and processed repeatedly,combined with Monte Carlo simulation results to determine the plan of region’s TD-LTE wireless network pre-construction case.
