Soft Frequency Reuse (SFR) can coordinate the inter-cell interference (ICI) by control the carriers and transmitting power. It will be used in the 5G. With the energy consumption increasing in the wireless network, the energy efficiency is an important index to evaluate the network performance in 5G. In this paper, we investigates the global energy efficiency optimization problem in SFR-based cellular networks. We formulate the global energy efficiency optimization as a fractional program model. It is very hard to solve directly the optimization model. To find the optimal solution of this model, we utilize the Lagrange function and KKT condition to attain the optimal transmitting power allocations. Then, we utilize the simulated annealing method to find the transmitting power allocations and sub-channel assignments. Finally, we make a numerical simulation to validate the algorithm proposed. The simulation results show that our algorithm proposed is feasible.
