Query: A Deep Learning-Based Approach for Cell Outage Compensation in NOMA
  Networks   Cell outage compensation enables a network to react to a catastrophic cell
failure quickly and serve users in the outage zone uninterruptedly. Utilizing
the promising benefits of non-orthogonal multiple access (NOMA) for improving
the throughput of cell edge users, we propose a newly NOMA-based cell outage
compensation scheme. In this scheme, the compensation is formulated as a mixed
integer non-linear program (MINLP) where outage zone users are associated to
neighboring cells and their power are allocated with the objective of
maximizing spectral efficiency, subject to maintaining the quality of service
for the rest of the users. Owing to the importance of immediate management of
cell outage and handling the computational complexity, we develop a
low-complexity suboptimal solution for this problem in which the user
association scheme is determined by a newly heuristic algorithm, and power
allocation is set by applying an innovative deep neural network (DNN). The
complexity of our proposed method is in the order of polynomial basis, which is
much less than the exponential complexity of finding an optimal solution.
Simulation results demonstrate that the proposed method approaches the optimal
solution. Moreover, the developed scheme greatly improves fairness and
increases the number of served users.
