Large number of antennas in transmitter and receiver side of 3D-MIMO can provide finer spatial granularity of beams and larger beamforming gain, and the number of simultaneously served UEs may also be increased compared with conventional LTE system. To support increased multi-user capacity in 3D-MIMO, DMRS needs to be further enhanced because DMRS only support up to 4 layers multi-user MIMO (MU-MIMO)...
