Method and apparatus for generating and transmitting code sequence in a wireless communication system

A method for transmitting a synchronization channel (SCH) signal by generating a code sequence in a wireless communication system, the method comprising:ngenerating a first code sequence (C1) having a first length by using a first variable (M1);generating a second code sequence (C2) having a second length by using a second variable (M2), wherein the M1 and the M2 are different from each other;generating the code sequence as a combination of the first code sequence (C1) and the second code sequence (C2); andtransmitting the code sequence as the SCH signal,wherein at least one of the first length and the second length is a prime number length, and the sum of the first length and the second length corresponds to a length of the SCH signal,wherein the combination of the first code sequence (C1) and the second code sequence (C2), each of which is generated using the different variables, provides a receiving end device with information about a cell identification and a location of the SCH within a radio frame.
