MESSAGE TRANSMISSION AND RECEPTION TECHNIQUE USING CHANNEL COMBINING AND SPLITTING

摘要

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, which is a transmission scheme for combining transmission signals through a first channel with a part of or all transmission signals through a second channel in a wireless communication system comprising at least two communication channels, the method comprising the steps of: splitting the messages into a first part to be transmitted to the first channel, which is a degradation channel, and a second part to be transmitted to the 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.
