Abstract: A method is provided for searching for a cell in a mobile station. The method includes receiving a downlink frame including a primary synchronization signal and a secondary synchronization signal. The secondary synchronization signal contains cell identity group information and the primary synchronization signal contains cell identity information within a cell identity group. The method also includes searching for a cell using the cell identity group information in the secondary synchronization signal and the cell identity information in the primary synchronization sign.

Abstract: The present invention relates to a method for generating a downlink frame including generating a first short sequence and a second short sequence indicating cell group information, generating a first scrambling sequence determined by the first synchronization signal, generating a second scrambling sequence determined by the first short sequence, scrambling the first short sequence with the first scrambling sequence, scrambling the second short sequence with at least the second scrambling sequence, and mapping a second synchronization signal including the scrambled first short sequence and the scrambled second short sequence in the frequency domain.
