Physical Signals
Synchronization signals (PSS and SSS), downlink reference signals (CRS, DM-RS,
CSI-RS, and PRS)
Primary and secondary synchronization signals are used by terminals for cell search. Terminals use the various reference signals to aid channel estimation and to support measurements.

- Synchronization Signals (PSS and SSS)
In LTE, there are two downlink synchronization signals which are used by the UE to obtain the cell identity and frame timing.
