【摘要】：国家工信部于2013年12月4日正式向国内3家运营商中国移动、中国电信和中国联通颁发了 TD-LTE经营许可,TD-LTE产业已经处于商用化攻坚阶段。到2014年年底,全国预计将建成50万个TD-LTE基站,超过340个城市提供4G商用服务,这一宏大目标与TD-LTE技术的成熟及前期良好的规划密不可分。本文就TD-LTE无线宏基站网络规划技术开展研究。首先阐述了国内外的通信技术及其布局的发展情况;现阶段无线网络规划技术的相关综述,其中包括GSM网络与WCDMA网络规划特点,并着重分析了 TD-LTE的关键技术,OFDM技术、MIM0技术和帧结构等;其次,根据TD-LTE的技术特点,明确了 TD-LTE宏基站网络建设的目标以及配置原则,并将其与原TD-SCDMA网络规划进行比对;然后,对TD-LTE宏基站进行实地勘察,明确设计原则、设计流程及设计方法;以收集到的数据资料进行仿真处理,分析调整;由于部署TD-LTE基站网络,大部分是在现有GSM或TD-SCDMA基站上建设,故重点阐述天馈建设方案等内容;最后,针对某地区进行2、3G网络的勘察摸底,整理收集到的数据反复仿真处理,同时结合蒙特卡罗仿真结果,确定该地区TD-LTE无线网络预建设情况。
[Abstract]:In December 4, 2013, the Ministry of industry and information (Ministry of industry and information) formally issued the TD-LTE operation license to 3 domestic operators, China Mobile, China Telecom and China Unicom. The TD-LTE industry has been in the stage of commercialization. By the end of 2014, 500 thousand TD-LTE base stations are expected to be built and more than 340 cities provide 4G commercial services. This grand goal and TD- The mature and good planning of LTE technology is inseparable. In this paper, the TD-LTE wireless macro base station network planning technology is studied. First, the development of communication technology and its layout at home and abroad, and the related summarization of wireless network planning technology at the present stage, including the characteristics of GSM network and WCDMA network planning, are mainly analyzed. The key technology of TD-LTE, OFDM technology, MIM0 technology and frame structure, and so on. Secondly, according to the technical characteristics of TD-LTE, the target and configuration principle of the network construction of TD-LTE Acer station are clarified and compared with the original TD-SCDMA network planning; then, the field investigation of the TD-LTE Acer station is carried out, the design principles, the design process and the design method are clear. The data collected from the collected data are simulated and analyzed. Because of the deployment of the TD-LTE base station network, most of them are built on the existing GSM or TD-SCDMA base station, so the construction scheme of the sky feed is focused on. Finally, the survey of the 2,3G network in a certain area is carried out and the data collected through the collection of data are repeatedly simulated and combined with Mont. Carol simulation results confirm the pre construction of TD-LTE wireless network in the area.
