Device-to-device (D2D) communications underlaying cellular networks are considered to be promising communication modes to improve network radio resource efficiency and provide higher transmission data rates to devices close to each other. However, when D2D communications reuse cellular resources, the resulting interference will cause significant performance loss to cellular users. In this paper, the spatial distribution of D2D communication users is modeled as a homogeneous spatial poisson point process. With this assumption, the closed-form expressions of the cumulative distribution functions (CDF) of the uplink interference power from the D2D communications and the signal power from the serving cellular users to the base station are derived, respectively. The approximate CDF of the uplink signal-to-interference-ratio of cellular users is also given in our analysis. More attractively, the analytical results can be used to help design the constraints on the configurations of D2D communications considering the minimum requirements of cellular users. Simulation results validate our analysis. Application examples of the analytical results are also given in this paper.
