Abstract:
Disclosed is a method and apparatus for reducing timing drift where a UE computes an NSSS based timing error using a cross correlation. Next, timing drift is measured as the difference in timing error at two NSSS instances separated by a time duration. The timing drift value can then be mapped to a raster offset.

Claim (Index 17):
A user equipment (UE) to reduce timing drift in a narrowband Internet-of-Things (NB-IoT) system, comprising:\n a memory; and a processor coupled to the memory, the processor configured to:\n track a timing error using a narrowband secondary synchronization signal (NSSS); \n compute an NSSS based time error estimate; \n estimate a timing drift based on the NSSS based time error estimate; \n map the estimated timing drift to a raster value based on a minimum distance criterion and a carrier frequency, the raster value corresponding to a drift value; \n determine a corrected timing drift based on the estimated timing drift and the drift value; and \n compensate for the corrected timing drift.
