TD-LTE is the next generation of mobile communication network mainstream technical ,2010 years of work in Beijing institute of letter organization the TD-LTE technology field test,China mobile the world expo in Shanghai construction TD-LTE demonstration nets, these test network construction show TD-LTE industry chain has initially end-to-end product ability.At present, the work of letter and China mobile plans through the construction TD-LTE network experiment to further advance the scale of industrial chain especially terminal-LTE TD product mature soon, accelerate progress commercial applications, so urgent need for TD-LTE wireless network planning technique for further research.In this paper the basic function of LTE network, indoor and outdoor network planning and implementation of the system engineering LTE to a detailed analysis of the key points,Including the cross time buttress interference, code resource planning and distribution system and LTE room points BBU and RRU project, and at the same time gives analysis data and conclusion improvement plan
