Research on Energy Efficiency Optimization of Full-duplex D2D Communication Links

Abstract

Aiming at the problems of interference and energy consumption caused by the introduction of Device-to-Device (D2D) communication in the cellular system, this paper proposes to first combine D2D communication technology with full-duplex transmission technology to construct a full-duplex D2D communication link scenario. Then, the power control and resource allocation problems are solved respectively to improve the energy efficiency of full-duplex D2D communication link under the condition of satisfying the minimum rate requirement and the power threshold. Finally, the sequential quadratic programming algorithm is used to solve the power control problem. The proposed adaptive tabu search algorithm is used to solve the problem of optimal resource allocation. The results show that, compared with the existing algorithms, the proposed algorithm has effective search operator and perturbation mechanism, and can solve the energy efficiency optimization problem of full-duplex D2D communication links with lower computational complexity.
