Title
(EN) PRECODED PILOT TRANSMISSION FOR MULTI-USER AND SINGLE USER MIMO COMMUNICATIONS
(FR) TRANSMISSION PRÉCODÉE DE PILOTE POUR COMMUNICATIONS ENTRÉES MULTIPLES, SORTIES MULTIPLES (MIMO) MULTI-UTILISATEURS OU UTILISATEUR UNIQUE
Abstract
(EN)
A method and apparatus includes an WTRU-specific reference signal scheme that provides efficient precoded pilot transmission and effective channel estimation using dedicated pilot signals. The method is efficient for both a single user (SU) and a multi user (MU) Multiple Input Multiple Output (MIMO) system.
(FR)
L'invention concerne un procédé et appareil qui comprend un schéma de signal de référence spécifique à l'unité d'émission/réception sans fil (WTRU) qui fournit une transmission précodée de pilote efficace et une estimation de canal réelle à partir de signaux de pilote consacrés. Le procédé est efficace à la fois pour un système à entrées multiples et sorties multiples (MIMO) pour un utilisateur unique (SU) et multi-utilisateurs (MU).
