Specifically, for Case 3, now receiving power drastically reduces suddenly, or even causes interrupted communication link, now
It is considered, because UE rotations or pedestrian stop that LOS path causes the obstruction of communication link, now to carry out according to the methods below
Wave beam tracks.
BS is not received by the ACK/NACK message of UE transmissions in the scheduled time, then judges the situation for Case3 occur.BS
The optimal N LOS for being then used in the storage of initial beam training stage immediately sends wave beam transmission data.
