  Device-to-device (D2D) underlaid cellular network, enabled with radio
frequency energy harvesting (RFEH), and enhanced interference management
schemes is a promising candidate to improve spectral and energy efficiency of
next generation wireless networks. In this paper, we propose a time division
duplexing (TDD)-based protocol, in which allows the devices to harvest energy
from the downlink transmissions of the base station, while controlling the
interference among D2D and cellular communication in the uplink. We propose two
schemes for transmission coordination, based on fixed transmission probability
(FTP) and adaptive transmission probability (ATP), respectively. In FTP, the
D2D transmitters that have harvested enough energy can initiate data
transmission with a fixed probability. Differently from this, in ATP a device
utilizes its sensing capability to get improved coordination and interference
control among the transmitting devices. We evaluate the network performance by
presenting an accurate energy model and leveraging tools from stochastic
geometry. The results on outage probability and D2D sum-rate reveal the
importance of transmission coordination on network performance. These
observations led to a solution for choosing the parameters of the ATP scheme
that achieves an optimal tradeoff between the D2D outage probability and number
of transmitting users.
