Energy harvesting from ambient radio-frequency (RF) sources has been a novel ap-
proach for extending the lifetime of wireless networks. In this paper, a cooperative

device-to-device (D2D) system with the aid of energy-constrained relay is considered.

The relays are assumed to be able to harvest energy from information signal and co-
channel interference (CCI) signals broadcasted by nearby traditional cellular users and

forward the source’s signal to its desired destination (D2D user) utilizing amplify-and-
forward (AF) relaying protocol. Time switching protocol (TSR) and power splitting

protocol (PSR) are proposed to assist energy harvesting and information processing

at the relay. The proposed approaches are applied in a model with three nodes in-
cluding the source (D2D user), the relay and the destination (D2D user), the system

throughput is investigated in terms of the ergodic capacity and the outage capacity,
where the analytical results are obtained approximately. Our numerical results verify

the our derivations, and also points out the impact of CCI on system performance. Fi-
nally, this investigation provide fundamental design guidelines for selecting hardware

of energy harvesting circuits that satisfies the requirements of a practical cooperative
D2D system.
