Title
(EN) METHOD AND APPARATUS FOR GROUP BASED PHYSICAL DOWNLINK SHARED CHANNEL (PDSCH) HYBRID AUTOMATIC REPEAT REQUEST (HARQ) -ACKNOWLEDGEMENT (ACK) FEEDBACK IN WIRELESS COMMUNICATION

Abstract
(EN) A user equipment (UE) is disclosed. The UE comprises a processor configured to perform operations comprising receiving a hybrid automatic repeat request process group (HPG) configuration signal from a base station associated therewith, wherein the HPG configuration signal comprises information of a plurality HARQ process groups (HPGs), each HPG comprising one or more HARQ processes of a set of HARQ processes configured for the UE. The operations further comprise receiving a downlink control information (DCI) from the base station, wherein the DCI comprises information that identifies one or more HPGs of the plurality of HPGs, the HARQ-ACK feedback information of which are to be included in a HARQ-ACK feedback signal that is triggered by the DCI. In addition, the operations comprise generating the HARQ-ACK feedback signal comprising the HARQ-ACK feedback information of HARQ processes associated with the one or more HPGs and sending the HARQ-ACK feedback signal to the base station.
(FR) L'invention concerne un équipement utilisateur (UE). L'UE comprend un processeur configuré pour effectuer des opérations consistant à recevoir un signal de configuration de groupe de processus de demande de répétition automatique hybride (HPG) en provenance d'une station de base (BS) qui lui est associée, le signal de configuration HPG comprenant des informations d'une pluralité de groupes de processus HARQ (HPG), chaque HPG comprenant un ou plusieurs processus HARQ d'un ensemble de processus HARQ configurés pour l'UE. Les opérations consistent en outre à recevoir des informations de commande de liaison descendante (DCI) en provenance de la station de base, les DCI comprenant des informations qui identifient un ou plusieurs HPG parmi la pluralité de HPG, dont les informations de rétroaction HARQ-ACK doivent être incluses dans un signal de rétroaction HARQ-ACK qui est déclenché par les DCI. De plus, les opérations consistent à générer le signal de rétroaction HARQ-ACK comprenant les informations de rétroaction HARQ-ACK des processus HARQ associés auxdits HPG, et à envoyer le signal de rétroaction HARQ-ACK à la station de base.
