Physical Signals

Synchronization signals (PSS and SSS), downlink reference signals (CRS, DM-RS, CSI-RS, and PRS)

Primary and secondary synchronization signals are used for by terminals for cell search. Terminals use the various reference signals to aid channel estimation and to support measurements.

Topics

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.
