1. An apparatus for a user equipment (UE), comprising:
memory to store information; and
processing circuitry coupled with the memory, the processing circuitry configured to:
determine a number of slots for a Tracking Reference Signal (TRS), wherein the number of slots is based on a subcarrier spacing of a bandwidth part (BWP) in a current component carrier for the UE and a minimum duration for accurate Doppler offset estimation; and
receive TRS based on the number of slots and a quasi co-location (QCL) relationship of the TRS, wherein the QCL relationship indicates that the TRS is Quasi-Co-Located (QCLed) with a Synchronization Signal (SS) block or a Channel State Information Reference Signal (CSI-RS).
