The OpenAirInterface Massive MIMO testbed [JK16] is built on the open source 5G platform OpenAirInterface. It is one of the world's first LTE full protocol stack compatible base stations equipped with large antenna array, which can directly provide services to commercial user equipments.The 5G mid-band is new spectrum in the 2-6 GHz range that was more recently opened up for 5G communication. The mid-band provides a capacity layer for urban and suburban areas, which peak rates in the 100's of Mbps. MIMO (MU-MIMO) Multiple-input, Multiple-output. MIMO stands for multiple input - multiple output. There are two main components in 5G NR network viz. UE (i.e. mobile subscriber) and gNB (i.e. base station). gNBs are connected with 5G Core in the backend. The connection from gNB to UE is known as downlink which uses PBCH, PDSCH and PDCCH channels for carrying different data/control informations.sented for 5G base stations. Each side of the antenna system consists of 3 layers with a total size of 44.4 29.6 0.1524 cm3, and contains 24 ports. Each port (subarray) consists of 2 2 patches on the top layer, their feeding network with pre-calculated phases is on the bottom layer and the ground plane is in the middle one. Band n79 (4.4-5 GHz): UL-MIMO (2Tx 23+23dBm) and 1Tx (26dBm) are supported for NR Band n79. So far, 3GPP RAN4 has completed the PC2 HPUE feature to improve uplink coverage for 5G Standalone (SA) deployments on NR bands. The following NR bands were approved to support PC2 HPUE for 5G NR SA in Release 15: Oct 16, 2021 · The number of antenna layers in 5G Massive MIMO can be a lot higher than the MIMO in 4G LTE. It employs tens or even hundreds of antenna elements within a single antenna panel. A 64 x 64 Massive MIMO antenna configuration is already used by some 5G network vendors but 256 x 256 is also possible. I think the main reason for Massive MIMO for 5G is 'there is no other choice'. It is highly likely that we will use very high frequency (mm Wave) signal in 5G. High frequency mean that. the size of single antenna will be very small and the aperture (the area for receiving energy) will be very small. To overcome this small aperture on reciever ...
