Patent ID: 8619540

Claim:
An operating method of a transmitting end for transmitting an orthogonal sequence in a wireless communication system, the method comprising: generating a sequence corresponding to sequence allocation information of the transmitting end among a plurality of candidate sequences; generating a signal string corresponding to the generated sequence; and transmitting the signal string over a channel defined for transmission of the signal string, wherein the sequence allocation information indicates a combination of at least one of a sequence length, a Zadoff-Chu sequence root index, orthogonal code indexes, and a cyclic shift offset, and the plurality of the candidate sequences comprises sequences that are obtained by extending a product of a covering code comprising a plurality of orthogonal codes and a Zadoff-Chu sequence through cyclic shift and multiplying the extended product by a master covering sequence, the extending through the cyclic shift and the multiplying being performed before an Inverse Fast Fourier Transform (IFFT), and wherein the covering code comprises a first orthogonal code to enhance a correlation characteristic and a second orthogonal code to increase the number the plurality of the candidate sequences.
