timing adjustment messages or in a “closed loop” scheme such as frequency tracking loop (FTL) to iteratively reduce the measurement error fluctuations.
These loops are often designated as code and carrier tracking loops.

Since the OFDM transmission is vulnerable to time and frequency offsets,
3.4 Tracking. After obtaining an initial estimate of the LTE frame timing, a tracking loop can be used to refine this estimate and keep track of any changes in TOA.
