1. A method of searching for a cell in a mobile station, comprising:

  • receiving a downlink frame including a primary synchronization signal and a secondary synchronization signal, wherein the secondary synchronization signal contains cell identity group information and the primary synchronization signal contains cell identity information within a cell identity group; and

    searching for a cell using the cell identity group information in the secondary synchronization signal and the cell identity information in the primary synchronization signal,wherein the secondary synchronization signal comprises a first short sequence and a second short sequence, the first short sequence is scrambled with a first scrambling sequence, and the second short sequence is scrambled with a second scrambling sequence and a third scrambling sequence,wherein the first scrambling sequence and the second scrambling sequence are determined based on the cell identity information contained in the primary synchronization signal, and the third scrambling sequence is determined based on the first short sequence.
