Query: On Optimal Policies in Full-Duplex Wireless Powered Communication
  Networks   The optimal resource allocation scheme in a full-duplex Wireless Powered
Communication Network (WPCN) composed of one Access Point (AP) and two wireless
devices is analyzed and derived. AP operates in a full-duplex mode and is able
to broadcast wireless energy signals in downlink and receive information data
in uplink simultaneously. On the other hand, each wireless device is assumed to
be equipped with Radio-Frequency (RF) energy harvesting circuitry which gathers
the energy sent by AP and stores it in a finite capacity battery. The harvested
energy is then used for performing uplink data transmission tasks. In the
literature, the main focus so far has been on slot-oriented optimization. In
this context, all the harvested RF energy in a given slot is also consumed in
the same slot. However, this approach leads to sub-optimal solutions because it
does not take into account the Channel State Information (CSI) variations over
future slots. Differently from most of the prior works, in this paper we focus
on the long-term weighted throughput maximization problem. This approach
significantly increases the complexity of the optimization problem since it
requires to consider both CSI variations over future slots and the evolution of
the batteries when deciding the optimal resource allocation. We formulate the
problem using the Markov Decision Process (MDP) theory and show how to solve
it. Our numerical results emphasize the superiority of our proposed full-duplex
WPCN compared to the half-duplex WPCN and reveal interesting insights about the
effects of perfect as well as imperfect self-interference cancellation
techniques on the network performance.
