Research And Application Of TD-LTE Networking And Interference

With the explosive growth of mobile data services, the medium is gradually migrating from the PC terminal to the mobile terminal, so the mobile networks in future needs to provide greater bandwidth and better quality of the network to meet the needs of users. This thesis firstly introduces the core technology of TD-LTE and the latest development trend of VoLTE, and then analyzes and studies the technology of TD-LTE dual carrier networking and interference avoidance.In terms of the network optimization, we firstly analyze the actual coverage difference between the total and the overlay network. The proposed method is based on the full coverage of the network. Finally, the application and testing of the dual carrier network and carrier aggregation technology in Nanjing mobile company are described.For interference avoidance, this thesis analyzes the causes of the interference, and then focus on the same frequency interference analysis between the TD-LTE control channel and the traffic channel in the systems. We also give the detailed description for the interference avoiding. Moreover, this thesis discusses the interference between TD-LTE systems. On the one hand, we discuss them under the F band, E band and D band. On the other hand, we present how to avoid such interference in practical engineering application specific solutions.In December 2013, TD-LTE was officially on use. Complex network environment and diversified customer needs brings a new challenge. This thesis provides a reference for the late TD-LTE network planning, construction and optimization.
