摘要 5G技术越来越近,但是LTE网络在未来还将长期存在,利用5G的Massive MIMO技术来提升LTE网络的容量非常有价值。通过对Massive MIMO技术提升容量的MU-MIMO理论进行分析,实现在TM9和TM3/TM4模式下的MUMIMO技术,并且在现网中分别进行了测试验证,基本达到了预期的效果。最后针对影响MU-MIMO性能的用户空间分布、激活用户数、用户业务类型等因素进行了定量分析,给出MU-MIMO在现网中应用的指导建议。 Though 5G technology comes, LTE network still exists in the future. It is valuable that 5G Massive MIMO technology is used to enhance the capacity of LTE network. MU-MIMO theory based on Massive MIMO technology to enhance capacity is analyzed. The MU-MIMO technology in TM9 and TM3/TM4 modes is implemented. It is tested in existing networks and achieves the desired effect. Finally, the factors to affect MU-MIMO performance such as user space distribution, number of active users and user service types are analyzed quantitatively and the suggestions on the application of MU-MIMO in existing networks are presented.
