What is synchronization in LTE?

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

What is timing synchronization?

Timing synchronization is the process by which a receiver node determines the correct instants of time at which to sample the incoming signal. Carrier synchronization is the process by which a receiver adapts the frequency and phase of its local carrier oscillator with those of the received signal.

Why synchronization is required in LTE?

However, 4G/LTE-A base stations need highly accurate time and phase synchronization to ensure smooth handovers between neighboring cells which enable consumers to get the Quality of Service they expect.

Is LTE synchronous?

Time synchronization of basestation clocks is essential to LTE operation. This is a summary of how to achieve it.
