Disclosed is a method of generating pilot sequences having double lengths of slots used for frame synchronization in an up or down link of a next generation mobile communication system which adopts W-CDMA mode. Disclosed is a method of generating pilot sequences having double lengths of slots used for frame synchronization and defined by 4l+2(l=1,2,3, . . . ) while providing a mathematical method of generating code sequences of slot length. The method of generating pilot sequences having double lengths of slots used for frame synchronization includes the steps of selecting a bit length of pilot sequences used for frame synchronization, selecting a first code sequence indicative of a maximum correlation value at a specific delay point of a correlation period and indicative of a minimum correlation value at the other delay points excluding the specific delay point, selecting a second code sequence indicative of the same correlation characteristic as the selected code sequence, and combining the selected code sequences to generate pilot sequences having the selected bit length.
