1. A method for transmitting a preamble sequence from user equipment to a base station to at least improve detection performance, the method comprising:

  • generating, by the user equipment, a specific sequence, having a length (L), from a Zadoff-Chu Constant Amplitude Zero Auto Correlation (CAZAC) sequence;

    applying, by the user equipment, a circular shift to the specific sequence by multiplying the specific sequence by an exponential sequence;

    repeating, by the user equipment, the circular-shifted specific sequence to generate a consecutive sequence having a length (N*L), wherein N is an integer greater than 1;

    generating, by the user equipment, the preamble sequence by concatenating a single cyclic prefix (CP) to a front end of the consecutive sequence; and

    transmitting, by the user equipment, on a random access channel, the preamble sequence to the base station to access a cellular network.
