Abstract

A user equipment (UE) includes a transceiver and a processor communicatively coupled to the transceiver. The processor is configured to receive, using the transceiver, a first Tracking Reference Signal (TRS) and a second TRS. The processor is further configured to receive, using the transceiver, at least one of a Demodulation Reference Signal (DMRS) or a signal on a Physical Downlink Shared Channel (PDSCH). For a parameter associated with the at least one of the DMRS or the signal on the PDSCH, the at least one of the DMRS or the signal on the PDSCH is quasi-co-located with the first TRS and the second TRS. The processor is further configured to use the first TRS and the second TRS to perform time and frequency synchronization.
