Abstract

Conformément à un mode de réalisation, la présente invention concerne le domaine technique des communications sans fil, en particulier un procédé, un système et un dispositif de configuration et de rapport d'information de mesure, utilisés pour configurer les informations de canal de multiples points de transmission et de multiples porteuses, de telle sorte qu'un équipement utilisateur (UE) n'est pas apte à rapporter les informations de canal de multiples points de transmission et de multiples porteuses, satisfaisant ainsi l'exigence de transmission CoMP. Le procédé de configuration d'informations de mesure du mode de réalisation de la présente invention comprend les opérations suivantes : un côté réseau détermine un ensemble d'informations de mesure selon le point de transmission sur la porteuse demandée à être mesurée par l'UE, l'ensemble d'informations de mesure comprenant les informations de mesure d'au moins un point de transmission ; le côté réseau configure l'ensemble d'informations de mesure déterminé pour l'UE. Du fait que le côté réseau configure le point de transmission sur la porteuse, l'UE peut rapporter les informations de canal de multiples porteuses et de multiples points de transmission, permettant ainsi de satisfaire l'exigence de transmission CoMP.
