UV-Plane Beam Mapping for Non-Terrestrial Networks in 3GPP System-Level Simulations
Dong-Hyun Jung, Sucheol Kim, Miyeon Lee +2
Due to the high altitudes and large beam sizes of satellites, the curvature of the Earth's surface can impact system-level performance. To consider this, 3GPP introduces the UV-pla…

Complete Power Reallocation for MU-MIMO under Per-Antenna Power Constraint
Sucheol Kim, Hyeongtaek Lee, Hwanjin Kim +2
This paper proposes a beamforming method under a per-antenna power constraint (PAPC). Although many beamformer designs with the PAPC need to solve complex optimization problems, th…
