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

  • receiving a downlink frame including a primary synchronization signal and two secondary synchronization signals which are different from each other; and

    identifying a cell by using the primary synchronization signal and at least one of the two secondary synchronization signal, wherein,in one secondary synchronization signal of the two secondary synchronization signal, a first short sequence scrambled with a first scrambling sequence and a second short sequence scrambled with a second scrambling sequence and a third scrambling sequence are alternately disposed on a plurality of sub-carriers,in the other secondary synchronization signal of the two secondary synchronization signal, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled with the second scrambling sequence and a fourth scrambling sequence are alternately disposed on a plurality of sub-carriers, andthe first short sequence and the second short sequence indicate cell group information,the first scrambling sequence and the second scrambling sequence are determined based on the primary synchronization signal, the third scrambling sequence is determined based on the first short sequence, and the fourth scrambling sequence is determined based on the second short sequence.
