Abstract

L'invention concerne un procédé et un appareil de communication sans fil, un dispositif et un support de stockage, se rapportant à la technologie des communications. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des premières informations de configuration envoyées par un dispositif de réseau d'une première cellule, les premières informations de configuration comprenant des informations de configuration relatives à un canal de radiomessagerie (510) ; et le dispositif terminal écoute le canal de radiomessagerie sur une seconde cellule sur la base des premières informations de configuration (520). Au moyen du procédé, lorsque la première cellule n'envoie pas le canal de radiomessagerie, le dispositif terminal peut acquérir un message de radiomessagerie au moyen de la seconde cellule. Pour ainsi dire, au moyen du mode d'amélioration d'un mécanisme de radiomessagerie, la consommation d'énergie du dispositif de réseau peut être réduite, tandis que les performances de communication de réseau sont assurées.
