Hello Experts.

What are the reason for time offset and frequency offset in a wireless communication?

2

Time offset could be due to bad sampler.
And frequency offset could be due to bad local oscillator or Doppler effect.

I am a bit confused by your question. Are you asking for the principle of Frequency and Time offset in signal processing?

How does the UE detect and adjust Timing Offset and Frequency Offset in 5G?

5

Time offset- By means of PSS and SSS detection.

Frequency offset- by means of SSB scanning.

After achieving initial synchronization, the UE can estimate and correct time and frequency offsets using reference signals.

For continuous time and frequency synchronization, the UE utilizes PBCH DMRS due to its periodic transmission.
