Device-to-device (D2D) underlaid cellular network, enabled with radiofrequency energy harvesting (RFEH), and enhanced interference managementschemes is a promising candidate to improve spectral and energy efficiency ofnext generation wireless networks. In this paper, we propose a time divisionduplexing (TDD)-based protocol, in which allows the devices to harvest energyfrom the downlink transmissions of the base station, while controlling theinterference among D2D and cellular communication in the uplink. We propose twoschemes for transmission coordination, based on fixed transmission probability(FTP) and adaptive transmission probability (ATP), respectively. In FTP, theD2D transmitters that have harvested enough energy can initiate datatransmission with a fixed probability. Differently from this, in ATP a deviceutilizes its sensing capability to get improved coordination and interferencecontrol among the transmitting devices. We evaluate the network performance bypresenting an accurate energy model and leveraging tools from stochasticgeometry. The results on outage probability and D2D sum-rate reveal theimportance of transmission coordination on network performance. Theseobservations led to a solution for choosing the parameters of the ATP schemethat achieves an optimal tradeoff between the D2D outage probability and numberof transmitting users.
