Abstract
(EN)
A method by which a terminal transmits a signal in an unlicensed band and an apparatus using the method are provided. The method allows a terminal to receive, from a base station, configuration information for transmitting an uplink signal to the base station within a channel occupancy time (COT) acquired by the base station; and transmitting the uplink signal to the base station within the COT on the basis of the configuration information. The configuration information indicates the type of channel access procedure, which should be performed by the terminal before the uplink signal is transmitted, and a time gap.
(FR)
L'invention concerne un procédé par lequel un terminal transmet un signal dans une bande sans licence et un appareil utilisant le procédé. Le procédé permet à un terminal de recevoir, en provenance d'une station de base, des informations de configuration pour transmettre un signal de liaison montante à la station de base pendant une durée d'occupation de canal (COT) acquise par la station de base ; et transmettre le signal de liaison montante à la station de base pendant la COT en fonction des informations de configuration. Les informations de configuration indiquent le type de procédure d'accès au canal, qui doit être effectuée par le terminal avant que le signal de liaison montante ne soit transmis, et un intervalle de temps.
(KO)
비면허 대역에서 단말의 신호 전송 방법 및 상기 방법을 이용하는 장치를 제공한다. 상기 방법은, 기지국이 획득한 채널 점유 시간(channel occupancy time: COT) 내에서 상기 단말이 상기 기지국으로 상향링크 신호를 전송하기 위한 설정 정보를 상기 기지국으로부터 수신하고, 상기 설정 정보에 기반하여, 상기 COT 내에서 상기 기지국에게 상기 상향링크 신호를 전송한다. 상기 설정 정보는, 상기 단말이 상기 상향링크 신호를 전송하기 전에 수행해야 하는 채널 접속 절차(channel access procedure)의 타입 및 시간 갭(time gap)을 알려준다.
