Abstract: front page image
(EN)A method for a terminal for detecting data transmitted according to the multiuser superposition transmission system comprises the steps of: receiving, from a base station, downlink control information comprising information for a codebook subset selected from a non-orthogonal codebook comprising an orthogonal subset and non-orthogonal subset; estimating a channel on the basis of a reference signal symbol or reference signal pattern corresponding to the selected codebook subset; and, on the basis of the channel estimation, detecting desired data symbols on the basis of the selected codebook subset, wherein the superposed data symbols are symbols comprising data not only for the terminal but also for other terminals.
(FR)L'invention concerne un procédé pour un terminal pour détecter des données transmises selon le système de transmission par superposition multi-utilisateur, comprenant les étapes suivantes : réception, de la part d'une station de base, d'informations de commande de liaison descendante contenant des informations pour un sous-ensemble de livre de codes sélectionné dans un livre de codes non orthogonal comprenant un sous-ensemble orthogonal et un sous-ensemble non orthogonal ; estimation d'un canal sur la base d'un symbole de signal de référence ou d'un motif de signal de référence correspondant au sous-ensemble de livre de codes sélectionné ; et, en se basant sur l'estimation du canal, détection des symboles de données désirés sur la base du sous-ensemble de livre de codes sélectionné. Les symboles de données superposés sont des symboles contenant des données non seulement pour le terminal, mais également pour d'autres terminaux.
(KO)단말이 다중 사용자 중첩 전송 방식에 따라 전송된 데이터를 검출하기 위한 방법은, 기지국으로부터 직교 서브세트 및 비직교 서브세트를 포함하는 비직교 코드북에서 선택된 코드북 서브세트에 대한 정보를 포함하는 하향링크 제어 정보를 수신하는 단계; 상기 선택된 코드북 서브세트에 대응하는 참조신호(Reference Signal) 심볼 또는 참조신호 패턴에 기초하여 채널 추정을 수행하는 단계; 및 상기 채널 추정에 기초하여 상기 선택된 코드북 서브세트에 기초하여 원하는 데이터 심볼들을 검출하는 단계를 포함하되, 상기 중첩 데이터 심볼들은 상기 단말 뿐만 아니라 다른 단말들을 위한 데이터를 포함하는 심볼들이다.
