CA 2605065

Apparatuses and methodologies are described that enhance performance in a wireless communication system using beamforming transmissions. According to one aspect, the channel quality is monitored. Channel quality indicators can be used to select a scheduling technique, such as space division multiplexing (SDM), multiple-input multiple output (MIMO) transmission and opportunistic beamforming for one or more user devices. In addition, the CQI can be used to determine the appropriate beam assignment or to update the beam pattern.

L'invention concerne des appareils et des méthodologies améliorant les performances d'un système de communication sans fil au moyen de transmissions de formation de faisceau. Selon l'un de ses aspects, la qualité de canal est régulée. Les indicateurs de qualité de canal peuvent être utilisés afin de sélectionner une technique de programmation, notamment un multiplexage dans l'espace (SDM), une transmission à entrées et sorties multiples (MIMO) et une formation de faisceau opportuniste pour un ou plusieurs dispositifs utilisateurs. En outre, des indicateurs de qualité de canal peuvent être utilisés afin de déterminer l'attribution de faisceau approprié ou la mise à jour du diagramme de faisceau.
