Abstract:
(EN) The present specification provides a method for transmitting a narrowband physical random access channel (NPRACH) preamble in a narrowband (NB)-Internet of Things (IoT) system supporting frame structure type 2. Specifically, the method performed by a terminal comprises the steps of: receiving control information related to an uplink-downlink configuration from a base station; and transmitting the NPRACH preamble to the base station on the basis of parameters related to NPRACH preamble transmission related to the received control information.
(FR) La présente invention concerne un procédé de transmission d'un préambule de canal d'accès aléatoire physique à bande étroite (NPRACH) dans un système à bande étroite (NB)-Internet des objets (IoT) prenant en charge un type de structure de trame 2. Le procédé exécuté par un terminal comprend les étapes consistant à : recevoir les informations de contrôle d'une configuration montante-descendante d'une station de base; et transmettre le préambule NPRACH à celle-ci sur la base de paramètres liés à la transmission du préambule NPRACH en rapport à l'information de contrôle reçue.
(KO) 본 명세서는 프래임 구조 타입(frame structure type) 2를 지원하는 NB(Narrow Band)-IoT(Internet of Things) 시스템에서 NPRACH(Narrowband Physical Random Access Channel) 프리앰블(preamble)을 전송하는 방법을 제공한다. 구체적으로, 단말에 의해 수행되는 상기 방법은, 업링크-다운링크 구성(uplink-downlink configuration)과 관련된 제어 정보를 기지국으로부터 수신하는 단계; 및 상기 수신된 제어 정보와 관련된 NPRACH 프리앰블 전송과 관련된 파라미터들에 기초하여 상기 NPRACH 프리앰블을 상기 기지국으로 전송하는 단계를 포함하는 것을 특징으로 한다.
