Title (EN) IMPROVED MIMO SYSTEM
(FR) SYSTÈME MIMO AMÉLIORÉ
Abstract:
(EN) Improved performance of downlink data transmission in a high speed downlink packet access, HSDPA, mobile communication system is described. Rank information, RI, and channel quality information, CQI, is obtained in a radio base station from a user equipment, UE, and this rank and CQI information is used in a medium access control- ehs, MAC-ehs, entity for determining a transport format and resource combination, TFRC, on a downlink channel. Figure 3 for publication.
(FR) L'invention se rapporte à l'amélioration des performances de transmission de données en liaison descendante dans un système de communication mobile à accès par paquets en liaison descendante haut débit (HSDPA). Des informations de rang (RI) et des informations de qualité de canal (CQI) sont obtenues en provenance d'un équipement utilisateur (UE) par une station de base radio, et ces informations de rang et de CQI sont utilisées par une entité de contrôle d'accès au support-ehs (MAC-ehs) pour déterminer un format de transport et une combinaison de ressources (un TFRC) sur un canal de liaison descendante.
