Abstract

La présente invention concerne un procédé et un dispositif de communication sans fil, permettant de configurer de manière flexible un signal de référence de suivi de phase, réduisant ainsi le nombre de sous-porteuses occupées par le signal de référence de suivi de phase et économisant ainsi le surdébit de ressources. Le procédé consiste : à déterminer, par un dispositif réseau, le motif d'un signal de référence de suivi de phase selon au moins le seuil d'un mode de codage de modulation correspondant au motif d'un signal de référence de suivi de phase demandé par un dispositif terminal, le seuil du nombre de blocs de ressources de planification correspondant au signal de référence de suivi de phase demandé par le dispositif terminal, et/ou le facteur d'influence du bruit de phase du dispositif terminal sur un signal reçu par le dispositif terminal, et au moins le mode de codage de modulation d'un dispositif réseau actuel qui planifie le terminal et/ou une largeur de bande du dispositif réseau actuel qui planifie le terminal ; et à transmettre au dispositif terminal le signal de référence de suivi de phase selon le motif déterminé du signal de référence de suivi de phase.
