Abstract: front page image
(EN)Provided are a method and device for signal transmission in a multi-node system comprising: a plurality of geographically distributed nodes; and a base station which is linked to and controls each of the plurality of nodes. The method comprises the steps of: mapping a plurality of code words onto a plurality of streams; mapping the plurality of streams onto at least one of the nodes in the plurality of nodes; carrying out MIMO precoding in which the streams that have been mapped in the at least one node are mapped to at least one transmission antenna; and transmitting the MIMO precoded signal to a terminal.
(FR)L'invention concerne un procédé et un dispositif pour la transmission de signaux dans un système multi-nœuds comprenant : une pluralité de nœuds répartis géographiquement ; et une station de base qui est reliée à et commande chacun de la pluralité des nœuds. Le procédé comprend les étapes consistant à : établir une correspondance entre une pluralité de mots de code et une pluralité de flux ; établir une correspondance entre la pluralité de flux et au moins l'un des nœuds parmi la pluralité de nœuds ; effectuer un pré-codage MIMO (Multiple Input Multiple Output, Entrées Multiples Sorties Multiples) consistant à mettre en correspondance les flux ayant été mis en correspondance dans ledit nœud avec au moins une antenne d'émission ; et émettre le signal pré-codé par codage MIMO vers un terminal.
(KO)지리적으로 분산된 복수의 노드들과 상기 복수의 노드들 각각과 연결되어 제어할 수 있는 기지국을 포함하는 다중 노드 시스템의 신호 전송 방법 및 장치를 제공한다. 상기 방법은 복수의 코드워드들을 복수의 스트림들에 맵핑하는 단계; 상기 복수의 스트림들을 상기 복수의 노드들 중 적어도 하나의 노드에 맵핑하는 단계; 상기 적어도 하나의 노드에서 맵핑된 스트림들을 적어도 하나의 전송 안테나로 맵핑하는 MIMO 프리코딩을 수행하는 단계; 및 상기 MIMO 프리코딩이 수행된 신호를 상기 단말에게 전송하는 단계를 포함하는 것을 특징으로 한다.
