Initial Beam Acquisition, Precoding, and Modulation, for Hybrid Digital/Analog mmWave Multiuser MIMO
While mmWave communications were expected to make a real breakthrough in 5G, it seems that the current technology trend has settled for more traditional frequency and signal bandwidths for the “access” segment, relegating high frequencies and large bandwidth for point-to-multipoint fixed wireless systems (e.g., wireless backhaul/fronthaul and last-mile data distribution solutions).
As a matter of fact, the major problems with the use of mmWaves for the access to mobile users is the need for fast and scalable initial beam acquisition schemes for two-sided large arrays (both at the BS and at the UE side), and the use of modulation formats that are well suited to hybrid digital analog beamforming, in terms of peak-to-average power ratio and robustness to high Doppler shifts.
In this talk we propose a set of basic concepts for a “beyond 5G” mmWave access scheme that would solve all the above issues.
