Abstract: In the near-field extremely large-scale multiple-input multiple-output (XL-MIMO) systems, the large bandwidth and massive antenna arrays lead to a significant beam-squint effect, causing ...
Resource Allocation for RIS-Assisted Mixed Near-and Far-Field Communication with Directional Antenna
Abstract: This paper studies resource allocation for a reconfigurable intelligent surface (RIS)-assisted mixed near- and far-field communication utilizing a directional antenna. The resource ...
