  In this paper, we provide an analytical framework to analyze the uplink
performance of device-to-device (D2D)-enabled millimeter wave (mmWave) cellular
networks. Signal-to- interference-plus-noise ratio (SINR) outage probabilities
are derived for both cellular and D2D links using tools from stochastic
geometry. The distinguishing features of mmWave communications such as
directional beamforming and having different path loss laws for line-of-sight
(LOS) and non-line-of-sight (NLOS) links are incorporated into the outage
analysis by employing a flexible mode selection scheme and Nakagami fading.
Also, the effect of beamforming alignment errors on the outage probability is
investigated to get insight on the performance in practical scenarios.
