Abstract:
1. A method of generating a downlink frame including a primary synchronization signal and a secondary synchronization signal in wireless communication system, comprising: generating a first short sequence and a second short sequence indicating cell group information, the cell group including a plurality of cells; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by a short sequence group-the wireless communication system uses a plurality of short sequences and the plurality of short sequences are grouped into a plurality of short sequence group-to which the first short sequence is assigned; scrambling the first short sequence with the first scrambling sequence and scrambling the second short sequence with the second scrambling sequence and the third scrambling sequence; and mapping the secondary synchronization signal that includes the scrambled first short sequence and the scrambled second short sequence to a frequency domain.
