Method for Optimizing the Beam Directions and Periodicity of Synchronization Signal Block (SSB) Transmission

A method for optimizing Synchronization Signal Block (SSB) sweep by a gNodeB in a 5G wireless system, the method comprising the steps of:

• sweeping, by a gNB, SSBs and collecting a user equipment (UE)-specific beam direction history;
• determining, by at least one of an artificial intelligence (AI) and machine learning (ML) engine, an optimal number of SSB beams and optimal set of beam directions based on at least the UE-specific beam direction history, and a complementary set of beam directions for the optimal set of beam directions;
• transmitting, by the at least one of the AI and ML engine, both the optimal set of beam directions and the complementary set of beam directions to the gNB;
• and
• transmitting, by the gNB, i) at every t1 milliseconds (ms), SSBs in the optimal beam directions, and ii) at every t2 ms, SSBs in the optimal set of beam directions as well as the complementary set of beam directions, wherein t2>t1 and t1, t2∈{5, 10, 20, 40, 80, 160} ms.
