QAROO frames the task offloading problem as a Markov Decision Process (MDP), where the AP acts as an agent learning to maximize the weighted sum computation rate. It defines states as dynamic channel conditions, actions as binary offloading decisions (local or offload to AP), and rewards as the optimal objective value of the resource allocation subproblem. This formulation allows the system to adaptively learn optimal policies in dynamic wireless environments, moving beyond static decision rules.
At its core, QAROO leverages Quantum Neural Networks (QNNs) to enhance feature representation. Classical channel states are encoded into quantum features via parameterized quantum circuits (PQCs), utilizing quantum superposition and entanglement. This quantum layer, comprising input encoding, entanglement, and variational layers, allows the model to capture complex, high-dimensional correlations in the input data more effectively than classical neural networks, improving the quality of offloading decisions.
Integrated with QNNs, a Multi-Head Self-Attention block dynamically weighs the quantum features to capture their importance and correlations across different channel dimensions. This mechanism allows QAROO to adaptively focus on the most informative channel conditions and user priorities. By strengthening feature representation, attention mechanisms improve decision robustness and overall model performance, especially in large-scale, dynamic MEC environments.
The QAROO framework integrates three key components: a Recurrent Neural Network (RNN) for temporal modeling of channel states, an Uncertainty-Guided Quantization (UGQ) module for diverse action generation, and a QNN+Attention hybrid architecture for enhanced feature representation. This architecture enables adaptive decision-making in dynamic wireless environments, where the RNN captures historical context, UGQ explores the action space efficiently, and QNN+Attention provides robust feature learning.
