Potential of D2D communications with fixed SINR targets. Average sum power and infeasibility probability are shown in Scenario 3 (7-cell system) using fixed SINR targets. When D2D candidates use D2D mode, the gain of D2D communications heavily depends on the maximum D2D distance and also on the position of the cellular UE with which the D2D link shares the cellular resources (uplink PRB).
