Improving Device-to-Device Communication Performance in 5G Networks through Joint Power Control and Resource Allocation

Abstract: The rapid growth in user population and the proliferation of diverse systems and services place a heavy burden on mobile communication networks. Device-to-Device (D2D) communication technology is considered one of the key technologies in 5G because of its ability to alleviate this burden and improve system performance. Most current research focuses on how to enhance transmission efficiency but proposed solutions tend to be highly complex. Therefore, the base station works for a long duration on this process, increasing the cost of communication equipment. To tackle this issue, we propose a low-complexity method that makes the use of power control and suitable resource allocation. A centralized network architecture is adopted to simplify this process and improve performance. Simulation results show that the proposed approach can significantly decrease interference, reduce power consumption, and increase throughput.
