“…Wireless Power Communication (WPC), where the smart terminals can harvest the energy from the far-field Radio-Frequency (RF) signals provided by energy access point, becomes a new approach to avoid replacing or recharging the batteries, reduce total cost, and prolong the lifetimes [1]. Simultaneous Wireless Information and Power Transfer (SWIPT) is a kind of WPC, where wireless devices can collect energy and receive information from RF signals at the same time [2][3][4][5]. In [6], Ioannis Krikidis team discussed the SWIPT technology and made a preliminary study on the allocation of wireless resources in SWIPT.…”

This paper proposes a new transmission strategy for device-to-device (D2D) multicast cooperative communication systems based on Simultaneous Wireless Information and Power Transfer (SWIPT) technology. The transmission block is divided into two slots. In the first slot, the source user transmits the information and energy to the help user by SWIPT. In the second slot, the help user uses the cellular spectrum and forwards the information to multiple receivers by using harvested energy. In this paper, we aim to maximize the total system rate, and to tackle the problem, we propose a two-step scheme: In the first step, the resource allocation problem is solved by linear programming. In the second step, the power-splitting coefficient value is obtained by taking the benefit of help user into account. Numerical results show that the proposed strategy not only effectively improves the overall throughput and spectrum efficiency but also motivates the cooperation.
