Abstract

La présente invention concerne un procédé et un dispositif de demande de ressource. Le procédé comprend les étapes suivantes : un dispositif terminal envoie des premières informations d'indication à un dispositif de réseau, les premières informations d'indication étant utilisées pour demander une ressource radio au dispositif de réseau, les premières informations d'indication étant également utilisées pour indiquer des informations d'exigences de ressource relatives à la ressource radio ; et le dispositif terminal reçoit des informations de programmation de ressource envoyées par le dispositif de réseau, les informations de programmation de ressource étant utilisées pour indiquer une première ressource, la première ressource étant une ressource attribuée par le dispositif de réseau au dispositif terminal. Les premières informations d'indication sont envoyées au dispositif de réseau, les premières informations d'indication étant utilisées pour demander une ressource radio au dispositif de réseau et pour indiquer, au dispositif de réseau, les informations d'exigences de ressource relatives à la ressource radio demandée par le dispositif terminal à être attribuée. De la sorte, d'après les premières informations d'indication, le dispositif de réseau attribue une ressource plus appropriée au dispositif terminal, ce qui améliore le taux d'utilisation de ressource et réduit le retard de transmission.
