Query: Power-Efficient Resource Allocation for MC-NOMA with Statistical Channel
  State Information   In this paper, we study the power-efficient resource allocation for
multicarrier non-orthogonal multiple access (MC-NOMA) systems. The resource
allocation algorithm design is formulated as a non-convex optimization problem
which takes into account the statistical channel state information at
transmitter and quality of service (QoS) constraints. To strike a balance
between system performance and computational complexity, we propose a
suboptimal power allocation and user scheduling with low computational
complexity to minimize the total power consumption. The proposed design
exploits the heterogeneity of QoS requirement to determine the successive
interference cancellation decoding order. Simulation results demonstrate that
the proposed scheme achieves a close-to-optimal performance and significantly
outperforms a conventional orthogonal multiple access (OMA) scheme.
