Abstract

L'invention concerne un procédé et un dispositif de programmation dynamique dans un équipement utilisateur et une station de base. L'UE reçoit un premier ensemble de RS à partir d'un premier groupe de ressources temps-fréquence, puis recherche une première signalisation. La première signalisation est une signalisation de couche physique. Une première séquence de RS est utilisée afin de déterminer le premier ensemble de RS. Au moins un parmi le premier groupe de ressources temps-fréquence et la première séquence de RS est utilisé afin de déterminer X2 sous-groupes de ressources temps-fréquence. Un maximum de X3 détections est réalisé sur la première signalisation, et X3 est un nombre entier positif qui n'est pas inférieur à X2. Un sous-ensemble de X3 détections est des X4 détections. Une quelconque des X4 détections est effectuée dans un des sous-ensembles de ressources temps-fréquence. L'invention permet de réduire efficacement les surdébits de signalisation dynamique de couche physique et d'améliorer également l'efficacité du spectre du système.
