A Study for the TD-LTE Network Planning Methodology and Performance Evaluation

This paper gives a TD-LTE network planning and performance evaluation methodology. In order to meet ever increasing traffic and datarate demands in the future, we propose, on a high level, three approaches: improving the macro layer radio performance, densifying the macro layer and complementing the macro layer with low power nodes. Combining with the proposed network planning and performance evaluation methodology, the paper made a scenario specific illustration on how to make a TD-LTE network evolution strategy and network planning via performance evaluation and solution comparison. Based on a system level simulation platform, we further demonstrate the feasibility of this study by evaluating two approaches: improving the macro layer radio performance by adding indoor antenna systems and densifying the macro layer, and get network planning key parameters. The results show that this network planning and performance evaluation methodology can provide guidance for TD-LTE network deployments and be of important value in making network evolution strategy.
