Abstract

La présente invention concerne un procédé et un dispositif pour une unité d'UE et une station de base liées aux communications sans fil. Dans un mode de réalisation, une station de base effectue une détection aveugle dans L1 des ressources de temps-fréquence et reçoit K1 signaux sans fil. Les K1 signaux sans fil sont envoyés respectivement par K1 terminaux, L1 étant un nombre entier positif et K1 étant un nombre entier non négatif. Les signaux sans fil transportent {informations de liaison montante, marqueur de planification}, et le marqueur de planification est utilisé pour déterminer si le terminal correspondant demande une planification continue. La présente invention réduit la probabilité de collision de liaison montante et empêche les gaspillages de ressources provoqués par la mise au repos.
