Abstract

Des modes de réalisation de la présente invention concernent une configuration de partie de bande passante pour la réception du signal de référence de positionnement. Un procédé permettant de configurer la BWP pour la réception du PRS comprend les étapes suivantes : générer, au niveau d'un dispositif terminal, une demande d'attribution d'une partie de bande passante du dispositif terminal pour recevoir un signal de référence de positionnement ; transmettre la demande au dispositif de réseau ; et recevoir une configuration cible de la partie de bande passante à partir du dispositif de réseau, la configuration cible étant déterminée par le dispositif de réseau en réponse à la réception de la demande d'attribution. De cette manière, la procédure de commutation BWP peut être simplifiée de manière significative et par conséquent le surdébit de signalisation peut être réduit.
