Abstract
As 5G NR continues to advance, beamforming is increasingly utilized at both the gNodeB (gNB) and user equipment (UE), complicating the management of spectrum sharing. The use of highly directional beamforming, with a larger number of antenna elements, is essential for achieving higher data rates in cellular systems and maintaining a stable link, even during mobility scenarios. However, when a gNB operates with highly directional beams in frequency bands designated for shared use, it may pose a potential interference risk to incumbents. This study explores the impact of 5G NR beamforming on gNB transmit power in spectrum sharing.
