Description
Radio Access Network Virtualization (vRAN) will
spearhead the quest towards supple radio stacks that adapt to
heterogeneous infrastructure: from energy-constrained platforms
deploying cells-on-wheels (e.g., drones) or battery-powered cells
to green edge clouds. We demonstrate a novel machine learning
approach to solve resource orchestration problems in energyconstrained
vRANs. Specifically, we demonstrate two algorithms:
(i) BP-vRAN, which uses Bayesian online learning to balance
performance and energy consumption, and (ii) SBP-vRAN,
which augments our Bayesian optimization approach with safe
controls that maximize performance while respecting hard power
constraints. We show that our approaches are data-efficient—
converge an order of magnitude faster than other machine
learning methods—and have provably performance, which is
paramount for carrier-grade vRANs. We demonstrate the advantages
of our approach in a testbed comprised of fully-fledged
LTE stacks and a power meter, and implementing our approach
into O-RAN’s non-real-time RAN Intelligent Controller (RIC).
