Abstract:
(EN) Provided are a method for determining a valid subframe for cell in a non-licensed band in a wireless communication system, and a wireless apparatus using the method. The method comprises: determining whether all orthogonal frequency division multiplexing (OFDM) symbols of the cell are usable; and when all of the OFDM symbols of the subframe are usable, determining whether the subframe is a valid subframe based on whether a channel state information-reference signal (CSI-RS) resource is present in the subframe.
(FR) L’invention concerne un procédé pour déterminer une sous-trame valide pour une cellule dans une bande non autorisée dans un système de communication sans fil, et un appareil sans fil utilisant le procédé. Le procédé consiste à : déterminer si tous les symboles de multiplexage par répartition orthogonale de la fréquence (OFDM) de la cellule peuvent être utilisés ou non ; et, lorsque tous les symboles OFDM de la sous-trame peuvent être utilisés, déterminer si la sous-trame est une sous-trame valide sur la base du fait de savoir si une ressource de signal de référence d’informations d’état de canal (CSI-RS) est présente ou non dans la sous-trame.
(KO) 무선통신 시스템에서 비면허 대역(unlicensed band) 셀에 대한 유효 서브프레임 결정 방법 및 상기 방법을 이용하는 무선 장치를 제공한다. 상기 방법은 상기 셀의 서브프레임의 모든 OFDM(orthogonal frequency division multiplexing) 심벌들을 사용할 수 있는지 여부를 판단하고, 상기 서브프레임의 모든 OFDM 심벌들을 사용할 수 있는 경우, 상기 서브프레임에 채널 상태 정보-참조 신호(channel state information-reference signal: CSI-RS) 자원이 있는지 여부를 기반으로 상기 서브프레임이 유효 서브프레임인지 여부를 결정하는 것을 특징으로 한다.
