In the 5G hybrid network, an energy efficiency optimization scheme based on TDMA system is proposed to optimize user association and power control and to improve network energy efficiency by optimizing user association and power control. With the aim of maximizing system energy efficiency, limit the maximum number of connected users of base stations, and design a user association algorithm. The Dinkelbach algorithm is used to optimize power control, to obtain the maximum energy efficiency of the system, and the proposed alternate optimization algorithm is simulated and verified.
