The method includes the steps of determining a first shift based on a first and 1 -1 a second cell identifiers for identifying a cell, and determining a second shift index based on the first cell identifier and transmitting © the SSS using a first sequence which is generated based on the first shift index and a second sequence which is generated based on the ei second shift index. In this case, the first shift index can be determined as K times a value determined based on the first and second cell 0 identifiers, where K is an integer equal to or greater than 3.
