Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.

Abstract: A method for communication beam transition in a communication system includes sending beam information on a first communication beam, receiving a beam switch command on the first communication beam, the beam switch command requesting a transition from the first communication beam to a second communication beam, simultaneously sending and receiving information on the first communication beam and the second communication beam, and ceasing sending and receiving information on the first communication beam when transition to the second communication beam is completed.
