    Abstract: A 5th-generation (5G) or pre-5G communication system which is to support a higher data transfer rate beyond a 4G communication system such as a long term evolution (LTE) is provided. The method for transmitting a downlink signal by a base station in a wireless communication system supporting non-orthogonal multiple access (NOMA) includes the steps of selecting a pair of terminals including one short-distance terminal and at least one long-distance terminal which will share an identical downlink transmission resource, generating a superimposed signal in which a signal for the short-distance terminal and a signal for the long-distance terminal are superimposed on one another, generating information necessary for cancelling the signal of the long-distance terminal from the superimposed signal, transmitting the generated information necessary for cancelling the signal of the long-distance terminal to the short-distance terminal, and transmitting the generated superimposed signal to the pair of terminals.

    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. The present disclosure provides a method for transmitting messages using a channel combining/splitting transmission scheme. The method comprises the steps of: splitting the messages into a first part to be transmitted to a first channel, which is a degradation channel, and a second part to be transmitted to a second channel, which is an enhancement channel, generating first modulation signals by performing a channel encoding and frequency quadrature amplitude modulation (FQAM) on the first part and generating second modulation signals by performing a channel encoding and quadrature amplitude modulation (QAM) on the second part, generating first transmission signals by combining the first modulation signals with a part of or all the second modulation signals and generating second transmission signals using the second modulation signals, and transmitting the generated first transmission signals and second transmission signals through the first channel and the second channel, respectively.
