OFDM and Its Wireless Applications: A Survey (2009, background): “More information in this topic can also be found in [167], [168], and the references therein.”
Cross-layer optimization for energy-efficient wireless communications: a survey (2009, background): “Note that, resource allocation in frequency-selective channels is far from a trivial application of the traditional utility scheduling schemes [58]–[63] and is much more difficult in that the utility depends on rate vector instead of the overall rate.”
Cross-layer optimization for OFDM wireless networks-part II: algorithm development (2005, background): “O ALLOCATE resources efficiently and fairly in orthogonal frequency division multiplexing (OFDM) wireless networks, utility-based cross-layer optimization, including dynamic subcarrier assignment (DSA), adaptive power allocation (APA), and joint DSA and APA, has been proposed in [1].”
A Survey on 5G Usage Scenarios and Traffic Models (2020, background): “As already commented, the full buffer traffic model has widely been adopted both in simulationbased [34], [35], [36], [37] and theoretical [38], [39], [40], [41] investigations due to its simplicity.”
Joint Optimization of Relay Strategies and Resource Allocations in Cooperative Cellular Networks (2006, neutral): “The NUM framework originated from the work of Kelly et al [10], and it has been applied to many physical-layer design problems [11].”
