D2D sum power and infeasibility in Scenario 1 (1 × 2 SIMO). Performance measures of interest are shown in D2D mode with optimized and heuristically set SINR targets (1 × 2 SIMO) in Scenario 1. The target sum rate is the same as in Figure 7, but the required sum power is just a fraction of that with fixed SINR targets (see Figure 7). In addition, the probability of infeasibility is very low, even when UE1 approaches the cell edge.
