Energy Efficiency Model of Parallel Transmission in Heterogeneous Networks

For the problem that the throughput is improved in the scene of the MUE (Multi-mode Users Equipment) Parallel transmitting high speed downlink service, but also brings a substantial increase in energy consumption. This paper proposes a multi network parallel transmission model, which through the analysis of the current research on multi network parallel transmission of energy saving ideas, defines two core contents of the energy efficiency model for parallel transmission of heterogeneous networks: optimal transmission rate allocation and network ranking and access decision rules. The specific idea is to make the ranking of all access network based on network resources in heterogeneous network. And according to the MUE service transmission requirements to decide which network needs to be selected for parallel transmission. Then getting the optimal allocation transmission rate of each bearing network, and the selected network provides downstream services for MUE according to the allocated rate to reduce energy consumption. Finally, the effectiveness of the improved model is verified by Matlab simulation analysis.
