基于通道重组的MIMO改造技术研究OA

The large-scale deployment of the fifth-generation mobile communication system(5G)has accelerated the construction of indoor digital scenes,but the indoor distributed systems of a large number of high-reputation scenes(such as transportation hubs and commercial centers)in the existing network are facing the dilemma of low-efficiency cells,and the traditional cell merging method cannot fully release the potential of MIMO.This paper proposes a MIMO transformation method based on channel reorganization,which realizes the low-cost upgrade of traditional indoor distributed systems through the coordinated scheduling of radio frequency units(RRUs)at the logical level and the integration of coverage areas.The practical results show that 5G indoor distributed systems achieve the effect of stag-gered MIMO through channel reorganization and merging technology,which solves the problem of low-zero cells in indoor distributed sys-tems and provides customers with a better network experience.
