Abstract:
A method and an apparatus for secondary synchronization in the Internet of things. The receiving apparatus extracts a frequency domain sample by applying channel estimation to a time domain sample of the secondary synchronization signal. Further, the receiving apparatus estimates a physical cell ID (PCI) and 80 ms frame timing (FT) based on decorrelation between a frequency domain standard signal of the secondary synchronization signal and the frequency domain sample.
