- W4308273105 abstract "This paper proposes a reconfigurable intelligent surface (RIS), also known as intelligent reflecting surface (IRS), that is carried by an unmanned aerial vehicle (UAV) to enhance the transmission rates of multiple ground users. We formulate the multiuser multiple-input, single-output (MU-MISO) system configuration problem to jointly optimize the active transmit beamforming at the base station and the phase shifts of the aerial RIS (ARIS) with the objective of maximizing the weighted sum rate (WSR). The solution is derived as an iterative optimization scheme by dividing the problem into two sub-blocks that are optimized alternately. Numerical results show that the proposed algorithm achieves high performance with a low computational complexity." @default.
