Generally, to determine a mobility status of a user equipment (UE), the UE may perform filtering or post-processing on one or more beam metrics. The UE may generate first order statistics for the beam metrics, and may use the first order statistics to generate second order statistics.

The UE may select appropriate beam management parameter values based on the determined mobility status.

Abstract: A portable blowing device includes a body and fans arranged in the body. Air channels are arranged in the body and extend in the length direction of the body to allow airflow to pass through. Wind shields are arranged in the air channels, and a periphery of the wind shield is closely connected with a side wall of the air channel so that a sub-air channel is formed between the wind shield and the side wall of the air channel.
