Policy-Driven DRL-Based TXOP Adaptation in NR-U and Wi-Fi Coexistence

Chiapin Wang, Po-Heng Chou, Shou-Yu Chen, Yi-Fang Yu

A policy-driven deep reinforcement learning framework models NR-U and Wi-Fi coexistence as a Markov decision process and uses reward design to learn TXOP control policies that set explicit operating points on the fairness-throughput curve.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Simulation results show that the proposed framework achieves a Jain fairness index above 0.9 under strict fairness control. Compared to absolute fairness, moderate fairness improves aggregate throughput by 68.22%, while the utility-based policy further enhances utility by 177.6%.

C2weakest assumption

The coexistence dynamics can be faithfully captured as a Markov decision process whose state and reward signals allow a DQN to learn stable policies that generalize beyond the simulated scenarios.

C3one line summary

A DRL framework with tunable reward policies controls TXOP in NR-U/Wi-Fi coexistence to achieve Jain fairness above 0.9 and throughput/utility gains of 68-177% in simulations.
