Multi-Connection to the Sky: Energy-Efficient Beamforming for Multi-Satellite Uplink Transmission With Lens Antenna Array

With the ever-increasing densification of low Earth orbit constellations, lens antenna array has become an attractive option for ground terminals to simultaneously connect to multiple satellites with improved coverage under insufficient energy supply. To this end, an optimization problem is formulat...
