Abstract

Sont divulgués des appareils, des procédés et des systèmes pour configurer un partage d'occupation de canal. Un procédé (500) consiste à recevoir (502) un signal dans un système de communication. Le signal comprend un indicateur de partage d'occupation de canal, et l'indicateur de partage d'occupation de canal est applicable à une caractéristique de transmission spatiale, à une caractéristique de réception spatiale ou à une combinaison de celles-ci. Le procédé (500) comprend l'application (504) de l'indicateur de partage d'occupation de canal à une transmission, à une réception ou à une combinaison de celles-ci.
