Abstract
The focus of this dissertation is on studying various packet scheduling and resource block (RB) allocation algorithms, for a variety of flow requirements, heterogeneous traffic, and architecture, in wireless OFDMA networks.In the second chapter, we investigate packet scheduling and RB allocation algorithms for realtime (RT) and non-realtime (NRT) packet-switched flows. We start by specifying different quality-of-service (QoS)-requirements for RT \& NRT flows and present different packet scheduling and RB allocation algorithms (including known cores and novel cores) based on the bit-rate driven utilities and the delay driven disutilities. We, then, summarize the machinery for attaining different fairness and QoS-requirements in a pair of classification tables (including a novel intuitive decomposition).When considering RT and NRT flows together, the commonly-used approach is the one based on performing two sequential algorithms of RT and NRT flows. This approach cannot exploit the potent existent multiuser diversity, in wireless OFDMA networks. In the third chapter, we propose a novel unified disutility minimization, in a common pool of RBs. Since the packet scheduling and RB allocation algorithms have taken place for RT and NRT flows from a common pool of RBs (without static priority separation), the overall spectral efficiency is increased. The novel formulations are used to devise computationally-efficient packet scheduling and RB allocation algorithm that surpass baseline algorithms. We also develop a novel general model for input-output bit-rate behaviour in packet scheduling and RB allocation of the heterogeneous traffic. This model sheds light on identifying different input load regions and understanding of the system in a simple intuitive manner.When it comes to providing very high bit-rate coverage, wireless networks require cost-effective radio access network (RAN) devices, such as multiuser enabled amplify-and-forward (AF) relays, with proper fair packet scheduling and RB allocation algorithms. These relays are cost-effective, simpler to implement, and introduce less delay in comparison to other relay based routers. In the fourth chapter, we develop novel fair packet scheduling and RB allocation algorithms in this kind of OFDMA based AF relays.Finally, we discuss a number of interesting research topics, as future directions, in the last chapter.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
