Research On Optimizing Resource Management Scheme Based On Energy Efficiency

With the development of technology,there are greater n eeds of communications.Previously,there have been a number of scholars and agencies working on how to further improve the capacity of the communications system and improve the system's spectrum utilization.With the development of next generation wireless communication system,there will be 50 billion equipment interconnection,communication capacity will be 1000 times the current network can provide.If simply rely on taking more energy to support such a large traffic,it will undoubtedly do pay the cost of energy and environmental pollution.Therefore,both academia and industry are studying how to improve the capacity of the system thousands of times more than the conventional system,under the condition of the same network energy consumption.In other words,they are studying how to improve the energy efficiency of the system thousands of times.As a result,energy efficiency is the key word in the next generation of wireless communications.In the multi-cell communication system,CoMP with the combination of MIMO technology is a good way to solve the interference of cell edge users and the problem of low throughput.Thus,this article researches and analyzes these two kinds of technology,then selects the appropriate model for the resource management of the whole system to provide better services,to support the different business requirements of users,and to optimize the energy efficiency and spectrum efficiency in the system.First of all,in this paper,the downlink communication processes and key technologies are introduced,and it analyzes the three kinds of CoMP patterns and four kinds of linear beamforming schemes.Then,we select CS/CB and SLNR scheme in this paper.Finally,the traditional resource management scheme and the definition of Qo S are introduced.Secondly,the paper researches energy efficiency in the system,and 3-cells communication scenarios are set up.It tries to meet the demand of the users' data rate by resource scheduling in the mathematic model.Then an iterative algorithm is designed for solving this problem.The proposed algorithm is compared with another three algorithms in the simulation and analysis.At the last,this paper analyzes the relationship between energy efficiency and spectrum efficiency in communication systems.The resource scheduling scheme is designed with the objective function of the weighted energy efficiency and spectrum efficiency.Furthermore,it analyzes the influence of system parameters to the two indicators,and explains how to choose appropriate parameters under different system requirements in order to meet the needs of different users better.Also,the GBR satisfaction of users and packet loss are analyzed in the system.
