Abstract: front page image
(EN)A method for user equipment (UE) to receive a reference signal in a cellular mobile communication system supporting narrowband-Internet of Things (NB-IoT) is disclosed. To this end, the UE receives, via at least one first subframe, a narrowband reference signal (NRS) for signal demodulation or measurement in NB-IoT and receives, via at least one second subframe, a narrowband positioning reference signal (NPRS) for location-based measurement in the NB-IoT, wherein information on the at least one second subframe is received from a base station as configuration information of the NPRS, and, in accordance with the configuration information of the NPRS, the UE operates by assuming that the NRS is not transmitted in a subframe configured with the second subframe.
(FR)L'invention concerne un procédé permettant à un équipement d'utilisateur (UE) de recevoir un signal de référence dans un système cellulaire de communications mobiles prenant en charge l'Internet des objets à bande étroite (NB-IoT). À cette fin, l'UE reçoit, via au moins une première sous-trame, un signal de référence en bande étroite (NRS) en vue d'une démodulation de signal ou d'une mesure dans le NB-IoT et reçoit, via au moins une deuxième sous-trame, un signal de référence de positionnement en bande étroite (NPRS) en vue d'une mesure basée sur la localisation dans le NB-IoT, des informations sur la ou les deuxièmes sous-trames étant reçues en provenance d'une station de base en tant qu'informations de configuration du NPRS et, selon les informations de configuration du NPRS, l'UE fonctionnant en supposant que le NRS n'est pas transmis dans une sous-trame configurée avec la deuxième sous-trame.
(KO)NB-IoT (Narrow Band Internet over Things)를 지원하는 셀룰러 이동통신 시스템에서 UE (User Equipment)가 참조 신호를 수신하는 방법이 개시된다. 이를 위해 UE는 NB-IoT에서 신호 복조 또는 측정을 위한 NRS (Narrowband Reference Signal)를 하나 이상의 제 1 서브프레임을 통해 수신하고. 상기 NB-IoT에서 위치 기반 측정을 위한 NPRS (Narrowband Positioning Reference Signal)를 하나 이상의 제 2 서브프레임을 통해 수신하되, 상기 하나 이상의 제 2 서브프레임에 대한 정보는 기지국으로부터 상기 NPRS 구성 정보로서 수신하며, 상기 UE는 상기 NPRS 구성 정보에 따라 상기 제 2 서브프레임으로 구성된 서브프레임에서는 상기 NRS가 전송되지 않는 것으로 가정하고 동작한다.
