Abstract
(EN)
The present invention relates to a wireless communication system and, particularly, to a method and a device therefor, the method comprising the steps of: monitoring a PDCCH candidate in an SS in units of sub-bands in a BWP including a plurality of sub-bands; and on the basis of the monitoring, detecting a PDCCH, wherein, in the BWP, the same CORESET is repeated per sub-band in a frequency domain, and a plurality of CORESETs included in the plurality of sub-bands are associated with the same SS.
(FR)
La présente invention porte sur un système de communication sans fil et, en particulier, sur un procédé et un dispositif associé, le procédé comprenant les étapes consistant à : surveiller un candidat de PDCCH dans un SS dans des unités de sous-bandes dans une BWP comprenant une pluralité de sous-bandes ; et détecter une PDCCH sur la base de la surveillance, le même CORESET, dans la BWP, étant répété par sous-bande dans un domaine de fréquence, et une pluralité de CORESET inclus dans la pluralité de sous-bandes étant associés au même SS.
(KO)
본 발명은 무선 통신 시스템에 관한 것으로서, 구체적으로 복수의 서브-밴드를 포함하는 BWP에서, 서브-밴드 단위로 SS에서 PDCCH 후보를 모니터링하는 단계; 및 상기 모니터링에 기반하여, PDCCH를 검출하는 단계를 포함하고, 상기 BWP에는 동일한 CORESET가 주파수 도메인에서 서브-밴드마다 반복되고, 상기 복수의 서브-밴드에 구성된 복수의 CORESET는 동일한 SS와 연관되는 방법 및 이를 위한 장치에 관한 것이다.
