Unlike LTE, 3GPP defines a directional version of synchronization signals for 5G NR. This plays an important role in beam management. Synchronization signals PSS, SSS, and PBCH are sent over SS blocks, which in turn are embedded inside larger SS bursts (Figure 1). Each SS block in a burst is mapped to a certain angular direction.
