Abstract

Certain aspects of the present disclosure provide techniques for configuring reference signals. A method that can be performed by a user equipment (UE) includes receiving a control message indicating a first quasi-co-location (QCL) of an aperiodic tracking reference signal (A-TRS), the A-TRS being associated with a periodic tracking reference signal (P-TRS); determining a second QCL of the P-TRS based on the first QCL of the A-TRS; setting a receive beam for receiving the P-TRS based on the second QCL of the P-TRS; and decoding one or more frames based on channel statistics estimated by the P-TRS received via the receive beam.
