Abstract
L'invention concerne une transmission de rétroaction d'état de canal d'un équipement utilisateur (ue) (800) vers une station (700) de base, formée d'un premier type détaillé ou d'un second type moins détaillé d'informations de rétroaction d'état de canal. Le procédé consiste d'abord à déterminer (403) si l'ue a reçu ou non une affectation de liaison montante de la station de base. Si l'ue a reçu une affectation de liaison montante, un premier type d'informations de rétroaction d'état de canal est transmis (404) à la station de base sur la ressource affectée. Cependant, si l'ue n'a pas reçu d'affectation de liaison montante, un second type d'informations de rétroaction d'état de canal est transmis (405) à la station de base. Différents type d'informations de rétroaction d'état de canal permettent à un ue et à une station de base associée d'utiliser les ressources disponibles plus efficacement, lors de la demande et de la distribution d'informations de rétroaction d'état de canal.
