Spectrum efficiency and energy efficiency can be developed by using the ultra-dense networks. Because of scalability and intrinsic densification, the interference avoidance and sustainable designs become more composite. More collaboration opportunities exist between them because the number of small cells is arranged. By using increased EE presentation with small offering of SE, we can find the Nash bargaining CE2MG, and also we calculate the connection between EE and SE. It can depend on the Nash product maximization problem. To increase the EE presentation with and without limitations of SE, we can attain the closed form of sub-optimal SE. Finally, we calculate the numerical results for the better performance of energy efficiency and courtesy of CE2MG by presenting the CE2MG algorithm.
