… However, we need to perform MK parallel optimizations to obtain different MK sets of power
NOMA coefficients. Considering this aspect, we may not gain any computational complexity …

… In this work, by optimizing the position of the UAV, the transmit beamforming, and the IRS
reflecting elements, the rate of the strong user was maximized while guaranteeing the target …
