Abstract

La présente invention concerne un procédé d'indication de ressources, un procédé d'émission de PUCCH et un dispositif côté réseau. Le procédé comporte les étapes consistant à: attribuer des ressources à deux équipements d'utilisateurs (UE) ou plus dans un réseau d'accès; et indiquer aux UE les ressources attribuées aux UE, les ressources étant utilisées par les UE pour émettre un canal physique de commande de liaison montante (PUCCH), et au moins deux UE parmi les deux UE ou plus partageant la même ressource de port 1 d'antenne pendant l'émission du PUCCH au moyen d'une diversité spatiale d'émission à ressources orthogonales (SORTD).
