Title (EN) METHOD AND DEVICE FOR TRANSMITTING/RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT DE TRANSMETTRE/RECEVOIR UN SIGNAL SANS FIL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선 통신 시스템에서 무선 신호 송수신 방법 및 장치
Abstract:
(EN) The present invention relates to a wireless communication system, and specifically, to a method and a device for the method which comprises the steps of: aggregating a LCell and a UCell in order to communicate with a base station; and transmitting a slotted uplink physical channel via only one slot among a plurality of slots of a subframe #m of the UCell, wherein the transmission of the slotted uplink physical channel includes performing a first CCA procedure X-time prior to a reference time point of the first slot of the subframe #m, and if the first CCA procedure fails, performing a second CCA procedure Y-time (Y>X) prior to a reference time point of the second slot of the subframe #m.
(FR) La présente invention se rapporte à un système de communication sans fil et, en particulier, à un procédé et à un dispositif pour le procédé qui comprend les étapes consistant : à rassembler une LCell et une UCell afin de communiquer avec une station de base; et à transmettre un canal physique de liaison montante à intervalles par le biais d'un seul intervalle parmi une pluralité d'intervalles d'une sous-trame (#m) de l'UCell, la transmission du canal physique de liaison montante à intervalle consiste à effectuer une première procédure d'évaluation de canal libéré (CCA pour Clear Channel Assessment) X fois avant un moment de référence du premier intervalle de la sous-trame (#m) et, si la première procédure d'évaluation CCA échoue, à effectuer une seconde procédure d'évaluation CCA Y fois (Y > X) avant un moment de référence du second intervalle de la sous-trame (#m).
(KO) 본 발명은 무선 통신 시스템에 관한 것으로서, 구체적으로 기지국과의 통신을 위해, LCell과 UCell을 병합하는 단계; 및 상기 UCell의 서브프레임 #m에서 복수의 슬롯 중 어느 하나의 슬롯에서만 슬롯화된(slotted) 상향링크 물리 채널을 전송하는 단계를 포함하고, 상기 슬롯화된 상향링크 물리 채널의 전송은, 서브프레임 #m의 첫째 슬롯의 기준 시점부터 X 시간 전에 제1 CCA 과정을 수행하고, 상기 제1 CCA 과정이 실패하면 상기 서브프레임 #m의 둘째 슬롯의 기준 시점부터 Y (Y > X) 시간 전에 제2 CCA 과정을 수행하는 것을 포함하는 방법 및 이를 위한 장치에 관한 것이다.
