Abstract
(EN)
The present document discloses a method for transmitting and receiving a downlink signal by a terminal and a base station in a wireless communication system supporting an unlicensed band, and devices supporting same. As one specific example, disclosed in the present document are various operation examples in which the terminal and the base station transmit and receive a downlink signal on the basis of a time point when the base station starts to occupy the unlicensed band for physical downlink shared channel (PDSCH) transmission on the unlicensed band.
(FR)
L'invention concerne un procédé d'émission et de réception d'un signal en liaison descendante par un terminal et une station de base dans un système de communication sans fil prenant en charge une bande sans licence, et des dispositifs prenant en charge ledit procédé. Dans un exemple spécifique, l'invention concerne divers exemples de fonctionnement dans lesquels le terminal et la station de base émettent et reçoivent un signal de liaison descendante sur la base d'un point temporel auquel la station de base commence à occuper la bande sans licence pour une transmission sur canal partagé de liaison descendante physique (PDSCH) sur la bande sans licence.
