Abstract:
(EN) Disclosed is a method and device for transmitting or receiving control information in a wireless communication system supporting the narrowband-Internet of things (NB-IoT). Specifically, a method for receiving downlink control information (DCI) by a terminal may comprise the steps of: when the terminal is configured to monitor, in a search space, first DCI predefined for single-scheduling, and receives configuration information related to multi-scheduling through higher layer signaling from a base station, monitoring, in the search space, second DCI including, further to the first DCI, a specific field indicating whether to activate the multi-scheduling; and monitoring the second DCI or third DCI predefined for the multi-scheduling, in a subsequent search space according to a value indicated by the specific field, wherein a payload size of the first DCI and a payload size of the third DCI are configured differently.
(FR) La présente invention concerne un procédé et un dispositif d'émission ou de réception d’informations de commande dans un système de communication sans fil prenant en charge un Internet des objets à bande étroite (NB-IoT). Spécifiquement, un procédé de réception d'informations de commande de liaison descendante (DCI) par un terminal peut comprendre les étapes consistant : lorsque le terminal est configuré pour surveiller, dans un espace de recherche, des premières DCI prédéfinies pour une planification unique, et lorsqu’il reçoit des informations de configuration relatives à la planification multiple par l'intermédiaire d'une signalisation de couche supérieure à partir d'une station de base, à surveiller, dans l'espace de recherche, des deuxièmes DCI comprenant, en outre des premières DCI, un champ spécifique indiquant s'il faut oui ou non activer la multi-planification ; et à surveiller les deuxièmes DCI ou des troisièmes DCI prédéfinies pour la multi-planification, dans un espace de recherche ultérieur selon une valeur indiquée par le champ spécifique, une taille de charge utile des premières DCI et une taille de charge utile des troisièmes DCI étant configurées différemment.
(KO) 본 발명에서는 협대역 사물 인터넷(NarrowBand-Internet of Things, NB-IoT)을 지원하는 무선 통신 시스템에서 제어 정보를 송수신하는 방법 및 이를 위한 장치가 개시된다. 구체적으로, 단말이 하향링크 제어 정보(downlink control information, DCI)를 수신하는 방법은, 상기 단말은 탐색 공간에서, 단일 스케줄링을 위해 미리 정의된 제1 DCI를 모니터링하도록 설정되며, 기지국으로부터 상위 계층 시그널링을 통해 다중 스케줄링과 관련된 설정 정보를 수신하는 경우, 상기 탐색 공간에서, 상기 제1 DCI에 상기 다중 스케줄링의 활성화 여부를 나타내는 특정 필드가 포함된 제2 DCI를 모니터링하는 단계; 및 상기 특정 필드가 나타내는 값에 따라, 후속하는 탐색 공간에서, 상기 제2 DCI 또는 상기 다중 스케줄링을 위해 미리 정의된 제3 DCI를 모니터링하는 단계를 포함하되, 상기 제1 DCI의 페이로드 크기와 상기 제3 DCI의 페이로드 크기는 서로 다르게 설정될 수 있다.
