What is 3D-MIMO large-scale array antenna technology?

The most important RF technology change in 5G NR is the application of 3D-MIMO large-scale array antenna technology, so much so that a significant portion of the NR physical layer architecture design content is adapted and updated around this technology, and here is an introduction to 3D-MIMO antenna technology in 5G systems from a comparative perspective.

Since 5G has eliminated cell-level reference signals in system design, antenna port signal transmission is based on UE exclusive reference signal (DMRS) for channel evaluation.

In order to make the mapping of “layer” to antenna port transmission data more uniform and simplified, the NR standard in the downlink shared channel implementation simply completely eliminated the cell-level reference signal based on LTE pre-coding matrix scheme, and use similar to LTE through the 3D-MIMO antenna technology to achieve the fugitive pre-coding scheme for SU/MU-MIMO, and with the simplification of the complex transmission mode type TM1-TM10.

The transmission diversity mode is also not defined, and the base station side is updated with beam fugue.

For air-division multiplexing, the NR downlink shared transmission channel can achieve up to dual codeword-8 layer mapping, and the UE obtains the transmission codeword information and the corresponding antenna port information by decoding the PDCCH DCI format 1-1.

For DMRS configuration type 1, the maximum dual codeword-8 layer transmission antenna port mapping is {1000 to 1007}, and for DMRS configuration type 2, the maximum dual codeword 8-layer transmission antenna port mapping for DMRS configuration type 2 is {1000, 1001, 1002, 1003, 1006, 1007, 1008, 1009}.

There are two main advantages of adopting such a design idea, firstly, the network base station side for UE about the transmission mode change is no longer delivered with the help of high-level signaling semi-statically, the UE obtains it entirely through the physical control channel dynamic decoding so that the interaction delay is greatly reduced.

In addition, with the elimination of the transmission mode type definition, the high-level signaling carrying the transmission mode type transformation is also simplified, reducing the network and terminal side signaling load overhead.
