Abstract:
(EN) The present invention relates to a transmitting/receiving apparatus and method in a multiuser MIMO (Multiple Input Multiple Output) system. According to the present invention, considering that each receiver having a multiplicity of antennas uses an antenna synthesis method or a receiving antenna selection method to receive a stream from a transmitter, channel information therefor is fed back such that channel information to feed back to the transmitter can be reduced and system performances can be improved.
(FR) L'invention concerne un procédé et un appareil d'émission/réception dans un système à entrée et sortie multiples (MIMO) multi-utilisateurs. Selon l'invention, si l'on considère que chaque récepteur, comportant une pluralité d'antennes, utilise un procédé de synthèse d'antennes ou un procédé de sélection d'antennes de réception pour recevoir un flux provenant d'un émetteur, alors les informations de voies sont rétropropagées, de sorte que ces informations à renvoyer à l'émetteur sont réduites et que les performances du système peuvent être améliorées.
(KO) 본 발명은 다중사용자(Multiuser) MIMO(Multiple Input Multiple Output) 시스템에서의 송수신 장치 및 방법에 관한 것이다. 본 발명에 따르면, 복수개의 안테나를 구비하는 각 수신단이 수신 안테나 합성 기법 또는 수신 안테나 선택 기법을 사용하여 송신단으로부터 하나의 스트림(stream)을 받는 경우를 고려하고 이에 대한 채널 정보를 피드백함으로써, 송신단으로 피드백되는 채널 정보를 감소시키고 시스템 성능을 향상시킬 수 있다.
