Abstract

Cette invention concerne des systèmes et des procédés de retour d'informations d'état de canal (csi) sur de petits canaux de commande. Selon certains modes de réalisation, un procédé de fonctionnement d'un second nœud connecté à un premier nœud dans un réseau de communication sans fil consiste à rapporter un retour de csi au premier nœud sur un canal physique. Selon certains modes de réalisation, ceci est accompli par : l'identification d'un sous-ensemble d'entrées de livre de codes à partir d'un livre de codes de coefficients de csi avancé; la sélection d'une entrée de livre de codes à partir du sous-ensemble d'entrées de livre de codes; et le rapport d'un indice de l'entrée de livre de codes sélectionnée à partir du sous-ensemble d'entrées de livre de codes. Ceci peut permettre un retour robuste et le transport sur le canal d'indicateurs de co-phasage et d'indice de faisceau de dimensions variables. Ceci peut également permettre un retour périodique de csi avancées sur le format de canal de commande de liaison montante physique (pucch) existant.
