Abstract:
(EN) Disclosed is a method for a terminal to receive system information in a wireless communication system. In particular, the method comprises: detecting, at a specific frequency position, a first synchronization signal block consisting of a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcasting channel (PBCH); determining, on the basis of a system information indicator included in the PBCH, whether system information corresponding to the first synchronization signal block is present within a first synchronization raster corresponding to the specific frequency position; and when it is determined that the system information corresponding to the first synchronization signal block is not present, determining, on the basis of the system information indicator, a second synchronization raster corresponding to a second synchronization signal block in which the system information is present.
(FR) L'invention concerne un procédé de réception, par un terminal, d'informations de système dans un système de communication sans fil. En particulier, le procédé consiste à : détecter, à une position de fréquence spécifique, un premier bloc de signal de synchronisation constitué d'un signal de synchronisation primaire (PSS), d'un signal de synchronisation secondaire (SSS) et d'un canal de diffusion physique (PBCH) ; déterminer, en fonction d'un indicateur d'informations de système inclus dans le PBCH, si des informations de système correspondant au premier bloc de signal de synchronisation sont présentes dans une première trame de synchronisation correspondant à la position de fréquence spécifique ; et lorsqu'il est déterminé que les informations de système correspondant au premier bloc de signal de synchronisation ne sont pas présentes, déterminer, en fonction de l'indicateur d'informations de système, une deuxième trame de synchronisation correspondant à un deuxième bloc de signal de synchronisation dans lequel les informations de système sont présentes.
(KO) 본 발명은, 무선 통신 시스템에서, 단말이 시스템 정보를 수신하는 방법을 개시한다. 특히, 상기 방법은, 특정 주파수 위치에서, 주 동기 신호(Primary Synchronization Signal; PSS), 부 동기 신호(Secondary Synchronization Signal; SSS) 및 PBCH(Physical Broadcasting Channel)로 구성된 제 1 동기 신호 블록을 검출하고, 상기 PBCH에 포함되는 시스템 정보 지시자를 기반으로, 상기 특정 주파수 위치에 대응하는 제 1 동기 래스터(Synchronization raster) 내에, 상기 제 1 동기 신호 블록에 대응하는 시스템 정보의 존재 여부를 결정하되, 상기 제 1 동기 신호 블록에 대응하는 시스템 정보가 존재하지 않는 것으로 결정된 경우, 상기 시스템 정보 지시자를 기반으로, 시스템 정보가 존재하는 제 2 동기 신호 블록에 대응하는 제 2 동기 래스터를 결정하는 것을 특징으로 한다.
