Abstract

To address the issues of spectrum inefficiency

high throughput

and low power consumption in 5G communications

we study the spectrum efficiency and energy efficiency issues. First

5G cognitive network model

where cognitive femtocell coexist with picocell

was built based on cooperative spectrum sensing scheme and dynamic time-division multiple-access scheduling mechanism. Then

formulate energy efficiency function and optimization problem with respect to transmission power. To resolve the non-convexity of the formulated optimization problem

Pareto-optimal solution was involved in global optimality. The simulation results show that the proposed schemes significantly enhance the energy efficiency of the cognitive femto user compared with another schemes

and ensure the accuracy and time agility of spectrum sensing.
