FAQ's

What is massive MIMO (mMIMO)?

Massive MIMO is essentially an antenna technology comprising an antenna array with more than 16 antennas ports (or better say modules known as sub-arrays). It is important to notice that the number of antennas elements per sub-array and the antenna ports on 5G base stations will increase significantly implementing antenna arrays configured with hundreds of antennas ports. When compared with traditional MIMO, Massive MIMO introduces beamforming technologies. It is important to emphasize that mMIMO is totally decoupled from air interface technologies hence can be used not only on 5G networks but also on traditional 4G networks. In addition, the multi-user MIMO technology is used to support spatial multiplexing transmission for more users, improving the spectral efficiency of the 5G system by several times. This feature improves user experience in high-capacity scenarios.

What is SU-MIMO in mMIMO?

SU-MIMO is a technique providing multiple transmission layers (also known as data streams or data pipes) spatially multiplexed (SMUX) into different beams towards one single handset for increasing throughput performance. So we can say in few words that in SU-MIMO, all resources are allocated to single user with the ultimate goal to improve single user throughput.

What is MU-MIMO in mMIMO?

5G MU-MIMO improve overall DL cell throughput by adding more user capacity into the sector, sharing same OFDM time-frequency resources between multiple users in same beam direction where the case of less throughput required per user. So the cell throughput will be improved by sending more data to more users in same TTI, a useful and practical technique for congested sectors to improve spectrum efficiency. According to standards MU-MIMO Rel.15 supports up to four layers per user and maximum 16 layers per cell, meaning that all combinations of four users with four layers or eight users with two layers or 16 users with single layer can be possibly paired at a time.
