Abstract

L'invention concerne un procédé mis en œuvre au moyen d'un dispositif sans fil (130). Le procédé permet de gérer une commande de ressource radio. Le dispositif sans fil (130) fonctionne dans un réseau de communication sans fil (100). Le dispositif sans fil (130) envoie (1004), après ou pendant un rétablissement d'une procédure de commande de ressource radio avec un premier nœud de réseau (111), une indication (1208) au premier nœud de réseau (111). Le premier nœud de réseau (111) fonctionne dans un réseau de communication sans fil (100). L'indication (1208) indique un ou plusieurs résultats de mesure d'une ou de plusieurs cellules (122). L'envoi (1004) est effectué avant la réception (1005) d'une indication supplémentaire (1209) provenant du premier nœud de réseau (111), l'indication supplémentaire (1209) indiquant une reconfiguration de la commande de ressource radio. L'indication supplémentaire (1209) est reçue sur la base de l'indication envoyée (1208) et/ou du ou des résultats de mesure.
