Abstract
Non-Orthogonal Multiple Access (NOMA) has emerged as a promising technology for enhancing spectral efficiency in 5G and beyond wireless communication systems. By allowing multiple users to share the same frequency spectrum simultaneously, NOMA enhances system capacity and serves a larger number of users. One of the critical issues in NOMA is the optimal allocation of power among users to balance fairness and spectral efficiency. This paper presents a review of power allocation strategies in NOMA, covering state-of-the-art techniques, challenges, and future directions. Furthermore, a literature review of at least 15 previous research studies is provided, emphasizing the evolution and optimization methods in power allocation schemes.
