ABSTRACT:
A method of performing cell search includes receiving a primary synchronization signal (PSS) comprising a primary synchronization code (PSC), acquiring an unique identity from the PSS, receiving a secondary synchronization signal (SSS) which is associated with a cell identity group, the SSS comprising two secondary synchronization codes (SSCs) and acquiring a cell identity which is defined by the unique identity within the cell identity group, wherein the two SSCs are respectively scrambled by using two different scrambling codes. Detection performance on synchronization signals can be improved, and cell search can be performed more reliably.
