DETECTION OF HIGH SPEED TRAIN SCENARIO AND INDICATION OF HIGH SPEED TRAIN (HST) MODE

Abstract:

A method of wireless communication by a base station detects a UE is in a high speed train scenario. The method also instructs the UE to enter a high speed train (HST) mode when the UE is detected to be in the high speed train scenario. The method further performs beam management in accordance with the HST mode. A UE (user equipment) for wireless communication detects when the UE is in high speed train scenario. The UE also reports the high speed train scenario to a base station and then receives instructions from the base station to enter a high speed train (HST) mode. The UE performs beam management in accordance with the HST mode.
