Claim:
A method of transmitting data at a first terminal in a wireless communication system, the method comprising: multiplying a plurality of data symbols, included in a first slot, with a first orthogonal sequence; multiplying a plurality of data symbols, included in a second slot, with a second orthogonal sequence; and transmitting, to a base station, the data symbols included in the first slot and the data symbols included in the second slot, wherein the first orthogonal sequence and the second orthogonal sequence are selected from orthogonal sequences of Table 1, and the index of the second orthogonal sequence is determined based on the index of the first orthogonal sequence according to Table 2.
