Abstract: front page image
(EN)The method, according to one embodiment of the present invention, by which in a wireless communication system a base station transmits signals to a plurality of terminals on the basis of non-orthogonal multiple access (NOMA), comprises the steps of: mapping first information bits for a first terminal and second information bits for a second terminal onto a first layer for the NOMA; modulating the first information bits and the second information bits which have been mapped on the first layer; and transmitting modulation symbols, which have been generated as a result of the modulation, to the first terminal and the second terminal, wherein the base station may map the first information bits and the second information bits onto the first layer, at a bit level before the modulation symbols have been generated.
(FR)Selon un mode de réalisation, la présente invention concerne un procédé par lequel, dans un système de communication sans fil, une station de base émet des signaux à une pluralité de terminaux sur la base d'un accès multiple non orthogonal (NOMA), et qui comprend les étapes consistant : à mapper des premiers bits d'informations pour un premier terminal et des seconds bits d'informations pour un second terminal sur une première couche pour le NOMA ; à moduler les premiers bits d'informations et les seconds bits d'informations qui ont été mappés sur la première couche ; et à transmettre des symboles de modulation, qui ont été générés suite à la modulation, au premier terminal et au second terminal, la station de base pouvant mapper les premiers bits d'informations et les seconds bits d'informations sur la première couche, à un niveau binaire avant que les symboles de modulation n'aient été générés.
(KO)본 발명의 일 실시예에 따른 무선 통신 시스템에서 기지국이 비-직교 다중 접속(NOMA)에 기반하여 다수의 단말들에 신호를 송신하는 방법은, 제1 단말을 위한 제1 정보 비트들과 제2 단말을 위한 제2 정보 비트들을 NOMA을 위한 제1 레이어 상에 맵핑하는 단계; 상기 제1 레이어 상에 맵핑된 상기 제1 정보 비트들과 상기 제2 정보 비트들을 변조하는 단계; 및 상기 변조 결과 생성된 변조 심볼들을 상기 제1 단말 및 상기 제2 단말에 송신하는 단계를 포함하고, 상기 기지국은, 상기 변조 심볼들이 생성되기 이전에 비트-레벨에서 상기 제1 정보 비트들 및 상기 제2 정보 비트들을 상기 제1 레이어 상에 맵핑 할 수 있다.
