英文摘要： Heterogeneous cellular network（HetNet）, which is constructed by employing hierachical coverage,spectrum and system, has been considered to be a very promising infrastructure for supportting the exponential growth in demand of higher data rates and onther services in future wireless cellular networks. However, development of hierachical networks and further improvement of system capacity are constrained by both spectral and energy resources. In this project we plan to explore the mechanism and methodology for utilize spectral and energy resources with high effeciency from system and network aspect,and investigate the tradeoff and optmization between spectral effeciency (SE) and Energy Effeciency (EE).Our research will be focused on inherent relationship between system SE and EE in heterogeneous cellular networks. Next,we plan to develop tradeoff analytical model and optimization framework and address dynamic system configuration problem based on our optimization framework. Our research objective is developing theoretical model and optimization framework, and effective dynamic system configuration mechanism and algorithm, to effectvely improve overall system SE and EE performance. The reseacrh results and deliveralbles of this project can provide some useful theorectical foundation and effective technique for developing next generation 5G mobile communication systems of our country. We are going to adopt game theory, optimization and modelling in our research and validate our theoretical results and proposed mechanism and algorithm through using analysis,simulation and prototype. High-level innovative theoretical achievements and effetive techniques in the area of next generation cellular networks will be produced in this project.
