Variance-Reduced Q-Learning over Static and Time-Varying Networks

Sreejeet Maity, Feng Zhu, Aritra Mitra, Robert W. Heath

We investigate a decentralized reinforcement learning problem involving multiple agents that interact with the same Markov Decision Process (MDP). The agents can exchange information over a network to collectively learn the optimal state-action value function. For this setting, w…

Energy Efficiency Optimization in Distributed MIMO vRAN via Cross-Layer Link Abstraction

Jaebum Park, Chan-Byoung Chae, Robert W. Heath

Virtualized radio access networks (vRAN) run the compute-intensive multiple-input multiple-output (MIMO) baseband as software on shared servers, which makes energy efficiency (EE) a primary design objective. Distributed MIMO vRAN consumes power across virtualized distributed unit…
