Abstract

La présente invention concerne un procédé et un appareil pour un équipement utilisateur (UE) et une station de base utilisée pour une communication sans fil. L'UE reçoit des premières informations et fait fonctionner un premier signal sans fil sur une première ressource d'interface radio. Les premières informations sont utilisées afin de déterminer K ressources d'interface radio, et les K ressources d'interface radio sont respectivement réservées pour K groupes de service, les groupes de service comprenant un ou plusieurs services. La ressource d'interface radio comprend au moins une parmi une ressource de domaine temporel, une ressource de domaine fréquentiel et une ressource de domaine de code. La première ressource d'interface radio est une des K ressources d'interface radio. Les K ressources d'interface radio correspondent à la même technologie d'accès sans fil. Dans la présente invention, en concevant les K groupes de service et les K ressources d'interface radio correspondantes, et en associant les groupes de services à des tranches de réseau, une pluralité de tranches de réseau peuvent partager la même technologie d'accès sans fil sans affecter les exigences de service, ce qui réduit les coûts de déploiement de réseau et améliore l'efficacité d'un système.
