CoMP(Coordinated Multiple Points) has been extensively studied recently. How to select the optimal coordinated set(dividing radius and cooperative BS)dynamically is an important research direction.The thesis studies regional planning issues of Coordinated Multi-Point Transmission with game theory, energy efficiency and resource efficiency. The main contents of this thesis can be summarized as follows:This section studies the relationship of the coordinated set and coordinated radius based on game theory and perfect feedback under single-user scenario. A game based on the Nash equilibrium in a simple game with complete information approach is played between the system capacity and the system load losses. According to Game Theory, the models are established towards the selection of coordinated set and coordinated radius respectively. Then we discusses the existence of the Nash equilibrium in three cases, which are fixed coordinated radius, fixed the number of the base stations and the joint optimization between the coordinated radius and the number of the base stations, the solution of Nash equilibrium is proposed and then gains the optimization selection of the coordinated radius and the number of the base stations that satisfies the equilibrium of ergodic capacity and system load.Finally, by means of numerical analysis to prove the existence of the Nash equilibrium and the optimal relationship between the cooperative radius and the number of base stations.This section studies the relationship of the coordinated set and coordinated radius based on energy efficiency. We discuss the relationship between system energy efficiency and coordinated set under the weight factor is one. For this model,the optimization goal is energy efficiency and the optimization variables are the cooperative radius and the number of base stations. We also discuss the relationship between system energy efficiency and coordinated set under the weight factor is not one, the relationship between the cooperative radius and the number of base stations is given. We also studies the relationship of the coordinated set and coordinated radius based on the lower bound of capacity. the optimal selection of the coordinated set and the coordinated radius is obtained.This section studies the relationship of the coordinated set and coordinated radius based on resource efficiency. For this joint optimization problem,the optimization goal is resource efficiency and the optimization variables are the coordinated radius and the number of base stations. Then we discuss the transformation of the problem of the resource efficiency optimization under the fixed balance factor and variable balance factor respectively,analyse the relationship between resource efficiency and coordinated radius, the number of base stations.The optimal selection of the coordinated set and the coordinated radius is obtained.
