1. An operation method of a first communication node in a communication system, the operation method comprising:
setting a first parameter for multiplexing first data to be transmitted to a first receiving node and second data to transmitted to a second receiving node, wherein the first data is composed first information bits, and the second data is composed of second information bits;
setting lengths of orthogonal sequences including first length of first orthogonal sequences corresponding to the first information bits, and second length of second orthogonal sequences corresponding to the second information bits;
setting a second parameter including a first phase information for the first information bits, and a second phase information for the second information bits;
generating orthogonal sequences based on the first parameter, the second parameter, and the lengths of the orthogonal sequences, wherein the orthogonal sequences comprise the first orthogonal sequences corresponding to the first information bits and the second orthogonal sequences corresponding to the second information bits;
mapping each of the first orthogonal sequences and the second orthogonal sequences to same radio resources; and
transmitting, to the first receiving node and the second receiving node, the first orthogonal sequences and the second orthogonal sequences using the same radio resources.
