Abstract

La présente invention concerne un procédé de communication, des dispositifs ainsi qu'un support de stockage. Le procédé de communication comprend les étapes suivantes: l'acquisition par un dispositif terminal d'une première information; et la réception et la transmission d'un service de diffusion/multidiffusion (MBS) conformément à la première information, la première information comprenant au moins une information de configuration relative à un service MBS. Le dispositif terminal peut être un dispositif à distance dans un scénario de relais ou un dispositif de relais, et apprend, au moyen de la première information, un paramètre de configuration du relais d'un service MBS, afin de pouvoir relayer le service MBS, permettant ainsi d'améliorer la qualité de communication d'un système.
