This paper introduces the results of DOCOMO-Huawei 5G large scale field trial, where the non-linear precoding schemes for downlink multi-user transmissions with massive MIMO is evaluated during the trial. According to the trial, the non-linear precoding scheme under investigated further improves the spectrum efficiency compared with linear precoding schemes, especially when the UEs are dense deployed with very small distance.
