Abstract

La présente demande concerne un procédé de configuration de ressources et un appareil de communication, applicables à un système de communication. Le procédé comprend les étapes suivantes : un premier dispositif terminal reçoit des premières informations en provenance d'un dispositif réseau, les premières informations étant utilisées pour indiquer un groupe de ressources de positionnement, le groupe de ressources de positionnement comprenant des ressources pour transmettre des signaux de référence de positionnement (PRS) entre des dispositifs terminaux, et le groupe de ressources de positionnement étant uniquement utilisé pour la communication de fonctions de positionnement. Le premier dispositif terminal utilise les ressources dans le groupe de ressources de positionnement pour envoyer et/ou recevoir des PRS, ce qui permet de résoudre le problème de conflits de ressources.
