Abstract
This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a user equipment (UE) may generate an indication of a first doppler shift associated with the wireless communication device moving with reference to a first target base station (BS), obtain, from the serving BS, a handover command for conditional handover (CHO) (with the handover command including a first trigger for handover to the first target BS), and synchronize with the first target BS during CHO after the first trigger is met, wherein the first trigger is associated with the first doppler shift. In another aspect, a serving BS generates the handover command for CHO and provides the handover command to the UE. The UE is to synchronize with the first target BS during CHO after the first trigger associated with a first doppler shift is met.
