Abstract

La présente demande concerne un procédé de communication sans fil et un dispositif de communication. Le procédé comprend les étapes suivantes : un nœud auxiliaire envoie un premier signal à un premier dispositif, le premier signal étant utilisé pour : la fourniture d'énergie et/ou de puissance au premier dispositif pour une communication avec un second dispositif et/ou le réveil du premier dispositif pour qu'il communique avec un second dispositif. Dans des modes de réalisation de la présente demande, un nœud auxiliaire peut commander un premier dispositif, par exemple, fournir de l'énergie et/ou de la puissance au premier dispositif ou, selon un autre exemple, réveiller le premier dispositif. Par comparaison avec une solution classique, la commande d'un premier dispositif par un second dispositif peut assouplir l'exigence concernant la distance entre le premier dispositif et le second dispositif, et améliorer la flexibilité de communication entre le premier dispositif et le second dispositif.
