TL;DR: In this article, the authors considered a scenario where an unmanned aerial vehicle (UAV) collects data from a set of sensors on a straight line, and the objective is to minimize the UAV's total flight time from a starting point to a destination while allowing each sensor to successfully upload a certain amount of data using a given amount of energy.

TL;DR: This paper proposes an efficient approximation method for solving the nonconvex centralized problem, using semidefinite relaxation (SDR), an approximation technique based on convex optimization, and analytically shows the convergence of the proposed distributed robust MCBF algorithm to the optimal centralized solution.

TL;DR: This paper investigates the application of simultaneous wireless information and power transfer (SWIPT) to cooperative non-orthogonal multiple access (NOMA) and proposes an iterative algorithm based on successive convex approximation (SCA) for complexity reduction, which can at least attain its stationary point efficiently.

TL;DR: In this article, a two-user downlink NOMA system with finite blocklength constraints is considered and a 1-D search algorithm is proposed to resolve the challenges mainly due to the achievable rate affected by the finite block length and the unguaranteed successive interference cancellation.

TL;DR: Time splitting schemes can outperform the ideal scheme and the PS scheme in interference dominated scenarios and are proposed as two practical time splitting schemes, namely the time-division mode switching (TDMS) and time- division multiple access (TDMA), in addition to the existing power splitting scheme.
