摘要：

Due to the directional nature of mmWave signal propagation, beam management plays a critical role in the performance of 5G mmWave deployments. However, the details of beam management in commercial deployments and its performance in real-world scenarios remain largely unknown. In this paper, we fill this gap by performing a comparative measurement study of the beam management procedure of two major US operators in Boston, MA. We study a number of beamforming parameters including beamwidth, number of beams, beam switching delay, and their impact on performance, and we explore the interplay between beam management and rate adaptation. We also investigate for first time Rx beam management on the UE side. Finally, we study the beam tracking performance and the quality of the selected beams for the two operators.
