High Altitude Platforms (HAPs) are platforms located 20 Km from the surface of the earth that have been designed as a new wireless infrastructure concept for the last few years. HAPs have several advantages compared to pre-existing terrestrial networks. In this study, the section on HAPs that is the focus of this research is the gateway link. Gateway links function to provide interconnection for other telecommunications networks on HAPs so that performance on these links must be good. For this reason, the Gateway HAPs link for 5G communication requires several additional technologies such as different frequencies and new multiple access techniques. Therefore, in this study, transmission simulations on HAPs will be carried out using Non-Orthogonal Multiple Access (NOMA) techniques and carried out at a frequency of 60 GHz, adding these techniques causes certain conditions so that additional techniques such as MIMO are needed to improve system performance. the. For the results to be displayed will use parameters such as Bit Error Rate (BER), rate between users, and Fairness. In this simulation, a comparison between NOMA and OMA is performed, the results show that NOMA can outperform OMA and can be used as an alternative for 5G communication. Then a number of simulation scenarios are performed to calculate the measurement parameters mentioned earlier. The results for BER calculations with differences in power allocation between users must be determined according to the user's circumstances in order to achieve good performance. And also to determine the minimum elevation angle for the HAPs system.
