Abstract

La présente divulgation concerne un procédé de communication, un terminal, un système de communication et un support de stockage. Le procédé de communication comprend les étapes suivantes : un premier terminal reçoit une première qualité de service (QoS) envoyée par un terminal relais, la première QoS étant une QoS correspondant à un service entre le premier terminal et le terminal relais, et la première QoS étant obtenue par la décomposition par le terminal relais d'une QoS correspondant à une liaison entre le premier terminal et un second terminal ; et le premier terminal envoie la première QoS à un dispositif de réseau. En utilisant le procédé de la présente divulgation, un dispositif réseau peut planifier avec précision une ressource d'envoi pour un premier terminal d'après une première QoS rapportée par le premier terminal.
