Abstract
Multiple input-multiple output (MIMO), massive MIMO, full-dimension MIMO (FD-MIMO) are the most recent remote advancements, which structure the purpose of takeoff for long term evolution systems. FD-MIMO is the promising technology proposed in the Third Generation Partnership Project to the transformation for the fifth-generation wireless communication schemes. FD-MIMO tramples several practical challenges imposed by massive MIMO systems such as interference, hardware limitations by the use of 2D active antenna array system which provides beam-forming in both azimuths as well as elevation domains in three-dimensional space. The traditional construction of big-scale planar arrays maximizes the spatial correlation is addressed using the dynamic device specific single down tilt beam-forming which minimizes the signal to interference ratio. That is further reduced by using FD-MIMO with incremental Redundancy and Regression monitoring techniques formulated as soft combining strategies. In this paper, the simulation results show maximizing of the minimum signal-to-interference ratio, spectral efficiency improvement and minimizing packet transmission time between eNodeB. Also, user equipment utilizing incremental redundancy shifting, hybrid automatic repeat request and regression monitoring strategies using network simulator 3.
