Title (EN) METHOD FOR ADJUSTING CONTENTION WINDOW SIZE IN WIRELESS ACCESS SYSTEM SUPPORTING UNLICENSED BAND, AND DEVICE FOR SUPPORTING SAME
(FR) PROCÉDÉ PERMETTANT DE RÉGLER UNE TAILLE DE FENÊTRE DE CONTENTION DANS UN SYSTÈME D’ACCÈS SANS FIL PRENANT EN CHARGE UNE BANDE NON AUTORISÉE, ET DISPOSITIF PERMETTANT DE PRENDRE EN CHARGE CE PROCÉDÉ

Abstract: front page image
(EN)The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when, as a result of performing the channel access procedure, it is determined that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal; receiving HARQ-ACK information corresponding to the transmission burst; and adjusting the CWS on the basis of the HARQ-ACK information corresponding to the first subframe of the transmission burst.
(FR)La présente invention concerne un système d’accès sans fil qui prend en charge une bande non autorisée, et fournit différents procédés permettant de régler une taille de fenêtre de contention, et des dispositifs permettant de prendre en charge ces derniers. En tant que mode de réalisation de la présente invention, un procédé permettant de régler une taille de fenêtre de contention (CWS) dans un système d’accès sans fil prenant en charge une bande non autorisée peut comprendre les étapes consistant : à réaliser une procédure d’accès à un canal ; lorsque, en conséquence de la réalisation de la procédure d’accès à un canal, il est déterminé qu’une cellule de desserte (Scell) dans la bande non autorisée est dans un état au repos, à transmettre une salve d'émission comprenant un signal de liaison descendante ; à recevoir des informations d’accusé de réception de demande de répétition automatique hybride (HARQ-ACK) correspondant à la salve d'émission ; et à régler la CWS sur la base des informations de HARQ-ACK correspondant à la première sous-trame de la salve d'émission.
(KO)본 발명은 비면허 대역을 지원하는 무선 접속 시스템에 관한 것으로, 경쟁 윈도우 크기를 조정하는 다양한 방법들 및 이를 지원하는 장치들을 제공한다. 본 발명의 일 실시예로서 비면허대역을 지원하는 무선접속시스템에서 경쟁 윈도우 크기(CWS)를 조정하는 방법은 채널 접속 과정을 수행하는 단계와 채널 접속 과정을 수행한 결과 비면허대역의 서빙셀(S셀)이 유휴 상태로 판단되면, 하향링크 신호를 포함하는 전송 버스트를 전송하는 단계와 전송 버스트 대응되는 HARQ-ACK 정보를 수신하는 단계와 전송 버스트의 첫 번째 서브프레임에 대응되는 HARQ-ACK 정보를 기반으로 CWS를 조정하는 단계를 포함할 수 있다.
