Abstract
(EN)
Various solutions for hybrid automatic repeat request (HARQ) feedback procedures for uplink transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive downlink control information (DCI) from a network node. The apparatus may determine whether the DCI is used to indicate HARQ feedback information corresponding to an uplink transmission. The apparatus may determine the HARQ feedback information according to the DCI in an event that the DCI is used to indicate the HARQ feedback information corresponding to the uplink transmission. The apparatus may determine whether to terminate the uplink transmission according to the HARQ feedback information.

L'invention concerne diverses solutions de procédures de rétroaction de demande de répétition automatique hybride (HARQ) relativement à un équipement d'utilisateur et un appareil de réseau dans des communications mobiles. Un appareil peut recevoir des informations de commande de liaison descendante (DCI) en provenance d'un nœud de réseau. L'appareil peut déterminer si les DCI sont utilisées afin d'indiquer des informations de rétroaction HARQ correspondant à une transmission en liaison montante. L'appareil peut déterminer les informations de rétroaction HARQ selon les DCI dans un cas où les DCI sont utilisées afin d'indiquer les informations de rétroaction HARQ correspondant à la transmission en liaison montante. L'appareil peut déterminer s'il faut mettre fin à la transmission en liaison montante selon les informations de rétroaction HARQ.
