UL edge average SE (Baseline)6.3.2 UL MU‐<strong>MIMO</strong> WITH DIV‐1XUL MU-<strong>MIMO</strong> with DIV-1X exhibits some moderate gains over the baseline of the order of 10%. Limitingfactors include the small number of receive antenna elements, the receiver technology with SICoutper<strong>for</strong>ming MMSE, the traffic distribution. The later affects the scheduler capability in identifying twosimultaneous UEs with target SINRs that allow <strong>MIMO</strong> detection/separation. The results below were per<strong>for</strong>medwith 10 users per cell; the presence of more users will likely increase the benefits.47
