| Summary: | This paper designs an efficient power allocation strategy for multiple energy harvesting(EH)-based D2D communication links reusing the same spectrum resource with one cellular user(CU). Based on this, a sum transmission rate maximization problem for EH-based D2D communication is formulated while maintaining a given transmission rate requirement for both CU and EH-based D2D links. Despite the non-convex property of the optimization problem, a two-step convex approximation(TSCA) algorithm is proposed which can obtain a tight low-bound solution. Finally, numerical simulation results indicate the performance of TSCA in aspects of transmission rate of D2D communication.
