Abstract

L'invention concerne un procédé et un dispositif d'émission et de réception d'informations de configuration de mesure. La présente invention consiste: à recevoir, en provenance d'un réseau, des informations associées à une configuration de mesure déterminée sur la base d'informations relatives à une cellule d'un nouveau type de porteuse (NCT) comprenant des porteuses NCT; à émettre, vers un terminal, un rétablissement de connexion RRC comprenant des informations de configuration de mesure pour configurer une mesure relative à NCT; et à recevoir, en provenance du terminal, un rapport de mesure comprenant le résultat d'une mesure effectuée par le terminal.
