Based on simulation results presented in the report, MIMO Transmission Schemes for LTE and HSPA Networks, it was shown that the relatively simple MIMO transmission scheme based on 2×2 closed-loop SM, at low user equipment (UE) speeds, can increase by 20 percent the downlink (DL) sector spectral efficiency relative to a single antenna transmission, as well as increase the cell edge efficiency by approximately 35 percent. More advanced antenna configurations can provide benefits that are significant for users that are receiving a strong signal as well as cell edge users.
