  Abstract

In device-to-device (D2D) communication underlaid cellular networks, a problem of balancing transmit power of a base station and D2D transmitters is important to effectively control mutual interference. To address this, we obtain analytical expressions for the ergodic spectral efficiencies by leveraging tools of stochastic geometry. With the derived expressions, an optimization problem is formulated to find the optimal power ratio between the D2D transmitter and the base station to maximize the sum spectral efficiencies. The simulation shows that using the optimal power ratio increases the sum spectral efficiencies. A benefit of the proposed optimal power ratio is that it does not have to be changed frequently.
