For wireless backhaul of heterogeneous networks (HetNet)
the existing researches mainly focus on improving the network throughput. However
few research is done on the coverage performance in the backhaul link. Therefore
this paper constructs a massive multiple input multiple output (MIMO) enabled multi-tier heterogeneous network model combing full-duplex (FD) and non-orthogonal multiple access (NOMA) technologies on small cell base stations (SBSs). The signal-to-interference ratio (SIR) is utilized to simulate the distribution of active SBS
and the interference is obtained at different types of receivers. Then
the mobile user (MU) downlink coverage probability closed-form expressions are deduced. Simulation and numerical results show that the SBS downlink coverage probability decreases as the downlink power sharing coefficient of the small cell increases. In addition
by comparing the effects of NOMA and orthogonal multiple access (OMA)
FD and half-duplex (HD) on downlink coverage performance
network performance of the proposed scheme is significantly improved.
