The ability to serve many users with high-speed transmission has made 5G as the promising candidate for the future generation of the wireless communication system. LTE could no longer support future demand with its current transmission rates. Various multiple access schemes have been proposed for 5G and NOMA as one of the candidates. Thus, this study has analysed the performance of NOMA in comparison to OMA in pedestrian and vehicular environments. To assure the Quality of Service (QoS), the metric of throughput is evaluated. The simulation was done using The Vienna 5G Link Level Simulator (LLS) and the result shows that NOMA cell centred user performed 50% better than OMA. Meanwhile, OMA outperformed NOMA in terms of cell edge user by 56%. The finding is in line with the characteristics of NOMA and OMA where NOMA users have to be in pair and share the same subcarrier while OMA users have their dedicated subcarrier for transmission.
