Optimal Joint Power and Subcarrier Allocation for Full-Duplex Multicarrier Non-Orthogonal Multiple Access Systems (2016, background): “However, even with the schemes proposed in [3]–[5], the spectral resources are still underutilized as some subcarriers may have to be assigned exclusively to users with poor channel conditions to ensure fairness in resource allocation.”
Energy Efficiency in Wireless Networks via Fractional Programming Theory (2015, methodology): “Fractional programming is employed to optimize different energy-efficient performance metrics, including the global energy efficiency of the cluster [127, 171], the sum of the individual energy efficiencies [69, 171], the product of the individual energy efficiencies [171], and the minimum of the en”
Fundamental Green Tradeoffs: Progresses, Challenges, and Impacts on 5G Networks (2016, background): “The above theoretical framework has been extended to OFDMA scenarios [41]–[44].”
Massive Access for 5G and Beyond (2020, background): “If each antenna is equipped with a dedicated RF chain, the number of RF chains can be very large resulting in high energy consumption [110].”
A Survey of Energy-Efficient Techniques for 5G Networks and Challenges Ahead (2016, background): “Among recent examples we mention [22], [27], [44] and [23] for OFDMA networks, and [26], [45], [46] and [47] for MIMO systems.”
