Sum power and infeasibility in Scenario 1 (1 × 2 SIMO). Required sum power and probability of infeasibility are shown with fixed SINR targets (1 × 2 SIMO) in Scenario 1. When the D2D pair communicates in D2D mode, the average sum power is significantly lower than the average sum power in cellular mode. This SINR target is also more often feasible in D2D mode than in cellular mode.
