D2D sum power and infeasibility in Scenario 1 (2 × 4 MIMO). Performance measures of interest are shown in D2D mode with optimized and heuristically set SINR targets (2 × 4 MIMO) without power loading optimization in Scenario 1. Compared with the results of Figure 8, we notice the dramatic decrease in the required power and the improved feasibility probability. Except for the UE1 cell edge positions, the same sum rate that is typically infeasible with fixed SINR targets becomes typically feasible with proper SINR target setting.
