Title
(EN) FRAME STRUCTURE OF UPLINK CONTROL INFORMATION TRANSMISSION CHANNEL FOR MIMO SYSTEM
(FR) STRUCTURE DE TRAME D'UNE VOIE DE TRANSMISSION D'INFORMATIONS DE COMMANDE DE LIAISON MONTANTE POUR SYSTEME MIMO
Abstract
(EN)
A frame structure of an uplink control information transport channel in the MIMO communication system using multiple transmission antennas and multiple reception antennas, constructed such that an uplink control information transport channel for transmitting control information with respect to each of the multiple transmission antennas includes three fields: a field for acknowledgement (ACK)/negative acknowledgement (NACK) for HARQ (Hybrid Automatic Retransmission Request), a field for CQI (Channel Quality Information) and a field for weight value information with respect to each transmission antenna. Because the control information for controlling each transmission antenna is effectively transmitted, signals transmitted at each transmission antenna of the MIMO system can be controlled in real time.

L'invention concerne une structure de trame d'une voie de transport d'informations de commande de liaison montante dans un système de communication MIMO utilisant plusieurs antennes de transmission et plusieurs antennes de réception. Cette structure de trame est conçue de façon qu'une voie de transport d'informations de commande de liaison montante servant à transmettre des informations de commande par rapport à chaque antenne de transmission comprenne trois champ : un champ d'accusé (ACK)/accusé négatif (NACK) pour une demande de retransmission automatique hybride (HARQ), un champ pour des informations sur la qualité de la voie (CQI) et un champ pour des informations sur la valeur de poids par rapport à chaque antenne de transmission. Du fait que les informations de commande permettant de commander chaque antenne de transmission sont efficacement transmises, les signaux transmis par chaque antenne de transmission du système MIMO peuvent être commandés en temps réel.
