(KO) 자율 전송을 위한 방법 및 장치
Abstract:
(EN) A method and an apparatus for autonomous transmission in an unlicensed band are provided, the method and apparatus comprising: a wireless device receiving semi-persistent scheduling (SPS) configuration for first uplink transmission, wherein the SPS configuration includes information regarding an SPS window indicating a time section at which the first uplink transmission is allowed; the wireless device receiving on a DL channel downlink control information (DCI) having an uplink grant that instructs second uplink transmission, wherein the uplink grant includes a second hybrid automatic repeat request process identifier (HARQid) for the second uplink transmission; and the wireless device performing the first uplink transmission in the SPS window when it is confirmed that a wireless medium is in an idle state by performing a listen before talk (LBT) in the SPS window, wherein a first HARQid for the first uplink transmission is not the same as the second HARQid.
(FR) La présente invention concerne un procédé et un appareil pour une transmission autonome dans une bande sans licence, le procédé et l'appareil comprenant les étapes suivantes : un dispositif sans fil reçoit une configuration de planification semi-persistante (SPS pour Semi-Persistent Scheduling) pour une première transmission en liaison montante, la configuration de planification SPS comportant des informations concernant une fenêtre de planification SPS indiquant une section temporelle pendant laquelle la première transmission en liaison montante est autorisée ; le dispositif sans fil reçoit sur un canal de liaison descendante (DL pour DownLink) des informations de commande de liaison descendante (DCI pour Downlink Control Information) ayant une autorisation de liaison montante qui ordonne une seconde transmission en liaison montante, l'autorisation de liaison montante comprenant un second identifiant de processus de demande de répétition automatique hybride (HARQid pour Hybrid Automatic Repeat reQuest identifier) pour la seconde transmission en liaison montante ; et le dispositif sans fil effectue la première transmission en liaison montante dans la fenêtre de planification SPS lorsqu'il est confirmé qu'un support sans fil se trouve dans un état inactif en effectuant une écoute avant de parler (LBT pour Listen Before Talk) dans la fenêtre de planification SPS, un premier identifiant HARQid pour la première transmission en liaison montante n'étant pas le même que le second identifiant HARQid.
(KO) 무선기기가 제1 상향링크 전송을 위한 SPS(semi-persistent scheduling) 설정을 수신하되, 상기 SPS 설정은 상기 제1 상향링크 전송이 허용되는 시간 영역을 나타내는 SPS 윈도우에 관한 정보를 포함하고, 상기 무선기기가 제2 상향링크 전송을 지시하는 상향링크 그랜트를 갖는 DCI(downlink control information)을 DL 채널상으로 수신하되, 상기 상향링크 그랜트는 상기 제2 상향링크 전송을 위한 제2 HARQid(hybrid automatic repeat request process identifier)를 포함하고, 상기 무선기기가 상기 SPS 윈도우에서 LBT(listen before talk)를 수행하여 무선 매체가 아이들함을 확인하면, 상기 SPS 윈도우에서 상기 제1 상향링크 전송을 수행하는 것을 포함하되, 상기 제1 상향링크 전송을 위한 제1 HARQid는 상기 제2 HARQid와 동일하지 않은 것을 특징으로 하는, 비면허 대역에서 자율 전송을 위한 방법 및 장치가 제공된다.
