“…Multiple Access Schemes: Orthogonal multiple access allows each user to obtain orthogonal communication resources in different degrees of freedom (DoF) [17] [18]. To put it another way, numerous users in OMA are eligible to transmit their signals on orthogonal channels without interference in the user's signal.…”

Based on the orthogonal multiple access (OMA) paradigm, multiple access techniques are now used in wireless networks. The capacity of OMA for orthogonal resources, which is already constrained, will be exceeded in the coming years by the demand for a significant number of users and efficient spectrum usage. Non-orthogonal multiple access (NOMA) is being considered for the next 5G and beyond releases. NOMA can offer high connection, low latency, and excellent spectral efficiency because several users can be handled in the same resource block at once. This work presents a thorough literature evaluation of the MIMO-NOMA and identifies several research gaps. Additionally, using Monte Carlo simulations, For the MIMO-NOMA heterogeneous network, simulation was performed to analyze the outage probability and ergodic capacity. The MIMO-NOMA HetNets system's performance is further evaluated using various SNR levels, number of clusters, user counts per cluster, and antenna count ratios.
