  Abstract

Ultra reliability and low latency communication(URLLC) is one of the 5G service types and requires a short data size and strict latency and reliability. In order to satisfy the requirements of URLLC, a non-orthogonal multiple access(NOMA) method with high spectrum efficiency has been proposed, but since it is a method of superimposing and transmitting signals by different power levels of two or more users composed of a user-pair, Signal attenuation according to distance and signals of other users within the same user pair act as interference, resulting in low reliability. In order to solve this problem, in this study, Coordinated multipoint communication and Genetic algorithm applied to improve the reliability of cell edge users were proposed, and performance evaluation was performed in terms of the finite block length.
