Abstract

See full text

A base station may receive from a user equipment (UE) a proactive notification that the UE will perform a beam switch from a first UE beam to a second UE beam. In response, the base station may determine a beam switch slot on which the UE will perform the synchronized beam switch, and perform a link transient mitigation operation for communications with the UE after UE beam switch and until updating channel state information associated with a new UE beam. The base station may then receive from the UE channel state information feedback for a channel associated with the second UE beam, and adjust downlink data transmission parameters to be aligned with the second UE beam based on the received channel state information feedback (CSF). The base station may also adjust uplink data transmission parameters based on a sounding reference signal transmitted by the UE over the second UE beam.
