Center node: "ran slicing in a uav network for embb service provision"
  Abstract: This paper is concerned with a problem of radio access network (RAN) slicing in a unmanned aerial vehicle (UAV) network for enhanced mobile broadband (eMBB) service provision. Unlike the literature focusing on RAN resource sharing in a UAV network, this paper simultaneously considers the enforcement of network slicing and the share of RAN resources. Specifically, this paper formulates the problem of RAN slicing in a UAV network as a time sequence optimization problem with a goal of providing an energy-efficient and fair eMBB service under constraints of both eMBB user equipments' quality of service requirements and UAVs' energy consumption and trajectories. This problem is a mixed-integer-non-convex-programming problem that is highly challenging to mitigate. As such, this paper proposes a framework that needs to repeatedly and separately enforce network slicing and optimize RAN resource allocation for mitigating it by exploring the Lyapunov optimization. Besides, this paper leverages a successive convex approximate method to transform the non-convex RAN resource optimization problem into an approximate convex optimization one. Simulation results show that the proposed framework can achieve significant performance gains as compared with other benchmark algorithms.
