Abstract
Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher than that of a 4G communication system such as long term evolution (LTE). According to the present disclosure, a method for transmitting a signal in a communication system supporting multi-user access comprises the steps of: transmitting, to a receiving device, information indicating a codebook formed on the basis of at least two signal constellations for sparse code multiple access (SCMA) transmissions; and transmitting signals on the basis of the codebook, wherein the at least two signal constellations are generated on the basis of energy values of symbols of a pre-given mother signal constellation and sizes of the symbols of the mother signal constellation.
