Downlink Beamforming with Pinching-Antenna Assisted MIMO Systems
A fractional-programming and block-coordinate-descent algorithm that jointly optimizes digital precoding and pinching-antenna locations achieves substantially higher multiuser downlink sum-rate than fixed-location antennas in Line-of-Sight simulations.
