Title
Field Experimental DL MU-MIMO Evaluations of Low-SHF-Band C-RAN Massive MIMO System with over 100 Antenna Elements for 5G.
Abstract
This paper describes our activities related to Massive Multi Input and Multi Output (MIMO) for use in a 5G radio access network (RAN). To achieve capacity enhancement and low power consumption, Massive MIMO has drawn attention as a key technology. Our research focuses on utilizing Massive MIMO in the low super-high-frequency (SHF) band, which is expected to be used for 5G commercial bands relatively soon, and on enhancing spectrum efficiency by spatial multiplexing with a low-SHF-band Massive MIMO antenna. The present work introduces a prototype low-SHF-band Centralized-RAN (C-RAN) Massive MIMO System including a low-SHF-band Massive MIMO Active Antenna System (AAS) that has 64 antenna elements, reports on outdoor and indoor downlink (DL) multi-user (MU) MIMO evaluations with the prototype system in both cases of 1 AAS unit and 2 AAS units, and presents the results of the evaluations. From the results, we confirmed that the prototype low-SHF-band C-RAN Massive MIMO system can optimize the performance with the minimum configuration of AAS units by changing the configuration appropriately depending on the environment.
