METHOD AND APPARTUS FOR DESIGNING AND OPERATING MULTI-DIMENSIONAL CONSTELLATION

In a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE), a method of a first terminal in a wireless communication system is disclosed and may include performing channel measurement, based on one or more first reference signals received from a base station; identifying channel distribution information between the first terminal and the base station, based on the measured channel; selecting one or more representative channel vectors (RCVs), based on the identified channel distribution information; generating one or more constellations corresponding to the selected one or more RCVs; transmitting constellation set information including the generated one or more constellations to the base station; and performing communication with the base station, based on the generated one or more constellations.
