The contradiction munication frequency resource shortage is promoting munication technology innovation. Along with the construction of the TD-LTE scale technology work, the Chinese mobile munication will be the era of LTE in ing few years. With the background, we need to strengthen the research of TD-work planning and design, for base of ing TD-LTE large-work construction. The target of the paper is to work planning and propose the feasible scheme. Firstly, the paper states basic principle of the TD-LTE, introduces the key technologys, such as OFDM, MIMO, link adaptive , and soon. Also, introduces unique characteristic of work planning paring to 2G/3G system, provides a basis for the specific study of TD-LTE work planning. In addition, based on the characteristics of TD-LTE system, the paper puts forward a detailed TD-LTE work planning process, and provides the corresponding needs analysis method, and a detailed analysis of the coverage, capacity, interference characteristics of the main factors and make reasonable suggestions. On the basis of above work, the paper uses Atoll software as the simulation platform, planed TD-work wireless for Guanlan Town of Guangdong Province . Through the simulation analysis, optimiz
