  The work presented in this paper deals with the issue of massive demands for
higher capacity. For that matter, we investigate the spectrum resource
management in outdoor mmWave cell for the uplink of cellular and D2D
communications. Indeed, we provide a first insight how to optimize the system
performance in terms of achievable throughput while realizing a compromise
between the large number of admitted devices and the generated interference
constraint. We propose a mathematical formulation of the optimization objective
which falls in the mixed integer-real optimization scheme. To overcome its
complexity, we apply a heuristic algorithm and test its efficiency through
simulation results with a particular regard to the BER impact in the QoS.
