主　　题：LTE A distributed energy saving mechanism CoMP equivalent cell principle energy saving rate 

摘      要：To reduce the energy consumption of the LTE-A system,a distributed energy-saving mechanism based on Co MP(Co MPDESM) is proposed to solve the inadequate coverage problem under the dormant ***,the network is divided into clusters based on the equivalent cell ***,we transfer global optimization into a group of ***,a joint processing-based cooperative cell selection model is constructed to determine cooperative cells and dormant ***,the compensative cells with a determined threshold are selected to control users ***,a simulation is implemented in *** show that the energy-saving rate can reach 36.4% and that the mechanism meets the network coverage ***,joint processing can be effectively applied in an energy saving mechanism and used to improve the network performance of edge users without increasing transmission power.
