Abstract:
1. A method of performing cell search in a wireless communication system, performed by a user equipment, the method comprising: searching a primary synchronization signal (PSS) comprising a primary synchronization code (PSC); searching a first secondary synchronization signal (SSS) comprising a first secondary synchronization code (SSC) and a second SSC, searching a second SSS comprising the first SSC and the second SSC, wherein the first SSC of the first SSS is scrambled by using a first scrambling code, the second SSC of the first SSS is scrambled by using a second scrambling code, the first SSC of the second SSS is scrambled by using the second scrambling code, and the second SSC of the second SSS is scrambled by using the first scrambling code, wherein the first and second SSCs are defined by m-sequences generated based on a first polynomial and the first and second scrambling codes are defined by m-sequences generated based on a second polynomial, wherein the first polynomial and the second polynomial satisfy reverse relationship.
