What is a 3D-MIMO antenna?

A key technology in 5G communication systems is large-scale array antenna technology, commonly known as 3D-MIMO antenna technology.

In the actual 4G network operating environment, 3D-MIMO antennas have been deployed on a large scale, which can achieve coverage enhancement while effectively relieving the pressure caused by capacity.

In order to better understand the key principles of 3D-MIMO technology and application practices, it is necessary to start from the basic MIMO technology principles, to explain the silk.

The official name of 3D-MIMO is Massive-MIMO, which is actually a high-gain array antenna.

Compared with the traditional 8T8R antenna, it not only achieves the horizontal plane assignment but also uses more oscillators and channels to achieve the vertical plane assignment.

The antenna assignment technology is to achieve the convergence of a narrow beam in a certain direction by electrically adjusting the phase of the array in different channels to achieve the gain of radiation energy, for 8T8R, all the oscillators belong to one channel in the vertical direction.

So the vertical dimension assignment cannot be achieved. In contrast, the 3D-MIMO antenna achieves the independent electrical adjusting of oscillators in different channels through channel isolation in the vertical dimension to complete the vertical dimensional assignment.

For the LTE broadcast channel, 3D-MIMO does not perform a similar assignment as PDSCH but adjusts the beam optimization by the weight of each polarization channel in 32 dual-polarization channels (64 channels).

In addition to the MU-MIMO operation of TM5 in LTE, TM7/8/9/10 can also provide MU-MIMO transmission.

Unlike TM5, which achieves MU-MIMO by explicit precoding matrix, TM7/8/9/10 achieves MU-MIMO by the weight assignment technique of antenna channels combined with feature matching of spatial channels.
