This paper propose Federated Edge-AI, an approach to enabling distributed learning and inference at the wireless edge - in close physical proximity to the data source. However, edge devices are inherently heterogeneous and lack energy and computation capacity, while wireless operating conditions vary dynamically, creating barriers to the efficiency and scalability of federated edge-AI systems. The authors work on a resource-efficient federated edge-AI cloud framework that jointly optimizes communication, computation, and energy while maximizing accuracy of the model. The proposed framework combines adaptive client participation, model compression, and bandwidth-aware aggregation mechanisms to achieve resource reduction in federated learning rounds. Futhermore, authors implement an intelligent resource scheduler, which manages the edge resource dynamically, based on device behaviour and channel conditions at the time of scheduling.

However, conventional methods suffer from high computational complexity due to the integration and inversion operations involving the covariance matrix. This paper proposes a robust adaptive beamforming algorithm with reduced complexity by reconstructing the covariance matrix. We employ orthogonal polynomial fitting to approximate the steering vectors associated with the broadened nulling regions. Hence, the interference subspace is directly obtained and the robustness of the interference suppression is enhanced while maintaining low complexity. Additionally, the algorithm is implemented based on the double-phase shifters (DPS) structure to control the antenna weights and phases. Compared to the traditional attenuator and single-phase shifter (ATT-SPS) structure, the DPS structure represents the weight vector as the sum of two constant modulus vectors.

As these systems scale, two realities dominate deployments: (a) devices must simultaneously serve heterogeneous tasks such as reconstruction for telepresence, segmentation for autonomy, and classification for analytics, and (b) encoders increasingly rely on multi-codebook hierarchies that share low-level semantics across tasks while specializing higher layers. These requirements expose a new optimization problem: how to jointly control radio resources, including subcarriers, power, code rate, and per-task codebooks in real time to optimize semantic utility under power and latency constraints. We address this by developing a practical controller, named ReSCo-SAC, that integrates a unified hierarchical multi-codebook design for multi-task semantics and an entropy-regularized reinforcement learner based on Soft Actor-Critic (SAC). The hierarchical design supplies vertical cross-task structure and a top-down quick-search mechanism to accelerate codeword lookup and prune the codebook choices online, and the learner turns semantic feedback into resource decisions that track the marginal semantic gain. We formalize the system model, an operational objective, and a hybrid action space that combines continuous radio controls with discrete codebook selections. We then detail an implementation that projects relaxed actions to a feasible OFDMA schedule, couples codebook choice to the hierarchical search, and uses online semantic measurements to tune the controller.
