1. A method of transmitting a preamble sequence in a mobile communication system, the method comprising:
- repeating a specific sequence, having a length (L), N times to generate a consecutive sequence having a length (N*L);
generating said preamble sequence by concatenating a single cyclic prefix (CP) to a front end of said consecutive sequence; and
transmitting, on a random access channel, said preamble sequence to a receiving side.

Abstract
Disclosed is a data transmission method in a mobile communication system. The data transmission method through a code sequence in a mobile communication system includes grouping input data streams into a plurality of blocks consisting of at least one bit so as to map each block to a corresponding signature sequence, multiplying a signature sequence stream, to which the plurality of blocks are mapped, by a specific code sequence, and transmitting the signature sequence stream multiplied by the specific code sequence to a receiver.
