Abstract

Divers aspects de la présente invention concernent un appareil de mesures de positionnement agrégées et de rapport. L'appareil (120), tel qu'un dispositif de configuration (un gNB ou un UE, par exemple), transmet une configuration de rapport (124) pour une mesure de positionnement à un dispositif de mesure (122). La configuration de rapport comprend une demande de rapport de mesures de positionnement agrégées et/ou de mesures de saut de fréquence de récepteur. L'appareil (120) reçoit un rapport de mesure de positionnement (126) qui comprend les mesures de positionnement agrégées et/ou les mesures de saut de fréquence de récepteur. L'appareil (120) détermine un emplacement d'un UE au moins en partie sur la base des mesures de positionnement agrégées et/ou des mesures de saut de fréquence de récepteur du rapport de mesure de positionnement.
