Query: Distributed Deep Reinforcement Learning for Functional Split Control in
  Energy Harvesting Virtualized Small Cells   To meet the growing quest for enhanced network capacity, mobile network
operators (MNOs) are deploying dense infrastructures of small cells. This, in
turn, increases the power consumption of mobile networks, thus impacting the
environment. As a result, we have seen a recent trend of powering mobile
networks with harvested ambient energy to achieve both environmental and cost
benefits. In this paper, we consider a network of virtualized small cells
(vSCs) powered by energy harvesters and equipped with rechargeable batteries,
which can opportunistically offload baseband (BB) functions to a grid-connected
edge server depending on their energy availability. We formulate the
corresponding grid energy and traffic drop rate minimization problem, and
propose a distributed deep reinforcement learning (DDRL) solution. Coordination
among vSCs is enabled via the exchange of battery state information. The
evaluation of the network performance in terms of grid energy consumption and
traffic drop rate confirms that enabling coordination among the vSCs via
knowledge exchange achieves a performance close to the optimal. Numerical
results also confirm that the proposed DDRL solution provides higher network
performance, better adaptation to the changing environment, and higher cost
savings with respect to a tabular multi-agent reinforcement learning (MRL)
solution used as a benchmark.
