Patent ID: 8155106

Claim:
A method of performing cell search in a wireless communication system, the method comprising: searching a primary synchronization signal (PSS), the PSS comprising a primary synchronization code (PSC); and searching a first scrambled secondary synchronization signal (SSS) and a second scrambled SSS, wherein the first scrambled SSS includes a sequence SSS 1 ( 0 ), . . . , SSS 1 ( 61 ) defined as SSS1(2 n )=SSC1( n )P1( n ), SSS1(2 n+ 1)=SSC2( n ) P 2( n ), where 0≦n≦30, SSC 1 ( n ) is a first secondary synchronization code (SSC), SSC 2 ( n ) is a second SSC, P1(n) is a first scrambling code and P2(n) is a second scrambling code, and wherein the second scrambled SSS includes a sequence SSS 2 ( 0 ), . . . , SSS 2 ( 61 ) defined as SSS2(2 n )=SSC2( n ) P 1( n ), SSS2(2 n+ 1)=SSC1( n ) P 2( n ), where 0≦n≦30, SSC 1 ( n ) is the first SSC, SSC 2 ( n ) is the second SSC, P1(n) is the first scrambling code and P2(n) is the second scrambling code.
