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 comprising a primary synchronization code (PSC); and searching a secondary synchronization signal (SSS) wherein the secondary synchronization signal includes a first secondary synchronization signal and a second secondary synchronization signal, each of the first and second secondary synchronization signal comprising a first secondary synchronization code (SSC) and a second SSC, the first SSC comprising a plurality of first SSC elements, the second SSC comprising a plurality of second SSC elements, wherein the locations of the first SSC elements and of the second SSC elements in the first secondary synchronization signal are swapped with the locations of the second SSC elements and of the first SSC elements in the second secondary synchronization signal, and wherein the first SSC and the second SSC are respectively scrambled by using two different scrambling codes.
