1. A method of a user equipment (UE) for lower layer based handover, the method comprising:
performing measurements of a plurality of channel state information reference signal (CSI-RS) samples from a source base station and a target base station;
triggering, at the UE, a lower layer handover procedure based on the performed measurements;
receiving, from the source base station, a Layer 1 (L1)/Layer 2 (L2)-based handover command instructing the UE to perform the lower layer handover procedure; and
in response to receiving, from the source base station, the L1/L2-based handover command, performing the lower layer handover procedure from the source base station to the target base station.
