POTENTIAL SOLUTIONS, CHALLENGES AND IMPLEMENTATION ISSUES FOR NOMA IN 5G COMMUNICATIONS

2022 Journal of Critical Reviews  
Non-Orthogonal Multiple Access (NOMA), a promising radio access technology for 5G and beyond networks, has recently attracted a lot of interest because of its higher spectral efficiency and capacity to serve multiple users simultaneously while maintaining the same time and frequency resources. 5G mobile networks will be able to accommodate at least 100 billion connections between devices, a 1000-fold growth in system capacity, improved coverage, high data rates, and ultra-low energy

A base station (BS) can serve numerous users at the same time, frequency, and code resource thanks to NOMA, which implements multiple access (MA) by utilizing a new dimension - the power domain. One of the fundamental NOMA methods that performs successive interference cancellation (SIC) at the receiver and superposition coding (SC) at the transmitter is the power domain NOMA
