Overview of Massive MIMO

In simple words, M-MIMO communication technology has a key player role in increasing spectral and energy efficiency through multiple antennas in base stations. On the other side, M-MIMO systems are usually equipped with 1000+ antennas in the single antenna array. Further, it also improves communication reliability and capacity by the simple linear process.

How does Massive MIMO work?

Generally, M-MIMO works on the principle of TDD communication mode. Moreover, it also uses UL-DL reciprocity of NR propagation through downlink beamforming. In particular, the BS array collects MIMO OFDM channel estimation from UL pilots which are transferred through terminals for learning channels in all directions

The two core technologies that create a strong foundation in 5G New Radio systems are spatial multiplexing and beamforming. Further, we have also given you some important advantages of using M-MIMO in cellular communication

    • To achieve strong signals, theoretically the end users are need to be placed closely to the base station
    • In the case of long-distance and weak signals, it uses cell edge
    • M-MIMO improves the cell-edge efficiency to accomplish high energy for end users in dedicated communication
  • Enhanced throughput
    • In MU-MIMO with spatial multiplexing use-cases, the systems can communicate with numerous UEs in identical frequency-time resources
    • Since, it accumulates the cell throughput and also enhance the spectral efficiency
