Abstract:
(EN) The present invention relates to a wireless access system supporting an unlicensed band, various methods for adjusting a contention window size, methods for performing a carrier sensing process in a single engine and a multi-engine, and an apparatus supporting the same. As one embodiment of the invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise: a step of setting a contention window size (CWS) necessary for performing a channel access process for each of priority classes; a step of performing a channel access process for a particular priority class in a channel in an unlicensed band on the basis of the set CWS; a step of performing a downlink transmission related to the particular priority class if it is determined that the channel in the unlicensed band is in an idle state as a result of the channel access process; and a step of making adjustments for all CWS' of priority classes if a triggering event, which relates to a downlink transmission and increases or reduces the CWS for the particular priority class, occurs.
(FR) La présente invention concerne un système d'accès sans fil prenant en charge une bande sans licence, divers procédés permettant d'ajuster la taille d'une fenêtre de contention, des procédés permettant de mettre en œuvre un procédé de détection de porteuse dans un moteur unique et un moteur multiple, et un appareil prenant en charge lesdits procédés. Selon un mode de réalisation de l'invention, un procédé permettant d'ajuster la taille d'une fenêtre de contention (CWS) dans un système d'accès sans fil prenant en charge une bande sans licence peut comprendre : une étape consistant à définir une taille de fenêtre de contention (CWS) nécessaire pour l'exécution d'un processus d'accès au canal pour chacune des classes de priorité ; une étape consistant à exécuter un processus d'accès au canal pour une classe de priorité spécifique dans un canal dans une bande sans licence sur la base de la CWS définie ; une étape consistant à effectuer une transmission de liaison descendante associée à la classe de priorité spécifique s'il est déterminé que le canal dans la bande sans licence est dans un état inactif suite au processus d'accès au canal ; et une étape consistant à procéder à des ajustements pour toutes les CWS des classes de priorité s'il se produit un événement déclencheur qui concerne une transmission de liaison descendante et agrandit ou réduit la CWS pour la classe de priorité spécifique.
(KO) 본 발명은 비면허 대역을 지원하는 무선 접속 시스템에 관한 것으로, 경쟁 윈도우 크기를 조절하는 다양한 방법들과 단일 엔진 및 다중 엔진의 캐리어 센싱 과정을 수행하는 방법들 및 이를 지원하는 장치에 관한 것이다. 본 발명의 일 실시예로서 비면허대역을 지원하는 무선접속시스템에서 경쟁 윈도우 크기(CWS)를 조정하는 방법은, 우선순위 클래스들 각각에 대해서 채널 접속 과정을 수행하기 위해 필요한 경쟁 윈도우 크기(CWS)를 설정하는 단계와 설정된 CWS를 기반으로 비면허대역의 채널에서 특정 우선순위 클래스에 대한 채널 접속 과정을 수행하는 단계와 채널 접속 과정의 결과 비면허대역의 채널이 유휴 상태로 판단되면, 특정 우선순위 클래스와 관련된 하향링크 전송을 수행하는 단계와 하향링크 전송과 관련되고 특정 우선순위 클래스에 대한 CWS를 증가 또는 감소시키는 트리거링 이벤트가 발생하는 경우, 우선순위 클래스들의 모든 CWS에 대해서 조정하는 단계를 포함할 수 있다.
