Abstract

La présente invention se rapporte au domaine d'une technologie de télécommunications et, en particulier, à un procédé de sélection d'un point de transmission (TP pour Transmission Point) participant à une transmission multipoint coordonnée (CoMP pour Coordinated MultiPoint) et à un dispositif utilisant ce dernier, qui résolvent des problèmes liés à une augmentation du trafic de rétroaction de mesure d'utilisateur et à une réduction des performances de transmission CoMP. Le mode de réalisation selon la présente invention concerne le procédé de sélection d'un point de transmission participant à une transmission CoMP, consistant à : transmettre, au moyen d'un équipement de réseau, à un équipement utilisateur (UE pour User Equipment) dans une couverture, des informations de mesure ; recevoir un premier ensemble de points TP mesuré en se basant sur les informations de mesure, renvoyé par chaque équipement utilisateur, et utilisé dans la transmission CoMP ; et déterminer, en fonction du premier ensemble de points TP renvoyé par chaque équipement utilisateur, un second ensemble de points TP participant à la transmission CoMP de chaque équipement utilisateur.
