NR - SSB Beam Detection

In 5G NR, beamforming is a crucial technique used to direct the signal toward a specific user equipment (UE) to maximize signal quality and strength. This is particularly important in the mmWave bands, where signals are more susceptible to attenuation and blockage.

The initial SSB beam detection process involves the gNB transmitting a set of SSBs across various directions(Each SSB burst is transmitted in different directions). The UE scans for these beams and measures the signal strength to determine which beam provides the best reception. The process is critical for establishing an initial link between the base station and the UE, allowing further communication to be optimized for the direction of the best signal.
