ABSTRACT:
A method of performing cell search includes receiving a primary synchronization signal (PSS) comprising a primary synchronization code (PSC), and receiving a secondary synchronization signal (SSS) comprising a first secondary synchronization code (SSC) and a second SSC. The first SSC and the second SSC are respectively scrambled by using a first scrambling code and a second scrambling code, and the first scrambling code and the second scrambling code are associated with the PSC. Detection performance on synchronization signals can be improved, and cell search can be performed more reliably.
