Abstract
(EN)
Provided are a method and device for adjusting automatic retransmission, a base station, and a terminal. The method comprises: detecting uplink retransmission service information of at least two target terminals, i.e., UEs, wherein after the channel avoidance LBT detection on an unlicensed-band grant-free uplink transmission resource fails, the at least two target UEs can share a same original retransmission alternative resource to perform automatic uplink retransmission; determining, according to the uplink retransmission service information, whether the original retransmission alternative resource is overloaded; if the original retransmission alternative resource is overloaded, adjusting related configuration information of a retransmission alternative resource to obtain retransmission adjustment configuration information; and delivering the retransmission adjustment configuration information to the target UEs, such that the target UEs perform data retransmission according to the retransmission adjustment configuration information. The method for adjusting automatic retransmission provided by the present invention can dynamically adjust related configuration information of automatic retransmission according to a change of a retransmission service, thereby reducing signaling overheads for retransmission scheduling.

L'invention concerne un procédé et un dispositif de réglage de retransmission automatique, une station de base et un terminal. Le procédé comprend : la détection d'informations de service de retransmission de liaison montante d'au moins deux terminaux cibles, c.-à-d. des UE, et une fois que la détection LBT d'évitement de canal a échoué sur une ressource de transmission de liaison montante sans autorisation de bande sans licence, les au moins deux UE cibles peuvent partager une même ressource alternative de retransmission d'origine pour effectuer une retransmission automatique de liaison montante ; la détermination, selon les informations de service de retransmission de liaison montante, de l'éventuelle surcharge de la ressource alternative de retransmission d'origine ; si la ressource alternative de retransmission d'origine est surchargée, le réglage des informations associées de configuration d'une ressource alternative de retransmission pour obtenir des informations de configuration de réglage de retransmission ; et la fourniture des informations de configuration de réglage de retransmission aux UE cible, de sorte que les UE cibles réalisent une retransmission de données selon les informations de configuration de réglage de retransmission. Le procédé de réglage de retransmission automatique proposé par la présente invention peut régler dynamiquement des informations de configuration associées de retransmission automatique selon un changement de service de retransmission, ce qui permet de réduire les surdébits de signalisation pour la planification de retransmissions.
